Analysis of Land Consumption Rates

Analysis of Land Consumption Rates CHAPTER ONE INTRODUCTION 1.1 Background to the Study Studies have shown that there remains only few landscapes on the Earth that are still in there natural state. Due to anthropogenic activities, the Earth surface is being significantly altered in some manner and mans presence on the Earth and his use of land has had a profound effect upon the natural environment thus resulting into an observable pattern in the land use/land cover over time. The land use/land cover pattern of a region is an outcome of natural and socio economic factors and their utilization by man in time and space. Land is becoming a scarce resource due to immense agricultural and demographic pressure. Hence, information on land use / land cover and possibilities for their optimal use is essential for the selection, planning and implementation of land use schemes to meet the increasing demands for basic human needs and welfare. This information also assists in monitoring the dynamics of land use resulting out of changing demands of increasing population. Land use and land cover change has become a central component in current strategies for managing natural resources and monitoring environmental changes. The advancement in the concept of vegetation mapping has greatly increased research on land use land cover change thus providing an accurate evaluation of the spread and health of the worlds forest, grassland, and agricultural resources has become an important priority. Viewing the Earth from space is now crucial to the understanding of the influence of mans activities on his natural resource base over time. In situations of rapid and often unrecorded land use change, observations of the earth from space provide objective information of human utilization of the landscape. Over the past years, data from Earth sensing satellites has become vital in mapping the Earths features and infrastructures, managing natural resources and studying environmental change. Remote Sensing (RS) and Geographic Information System (GIS) are now providing new tools for advanced ecosystem management. The collection of remotely sensed data facilitates the synoptic analyses of Earth system function, patterning, and change at local, regional and global scales over time; such data also provide an important link between intensive, localized ecological research and regional, national and international conservation and management of biological diversity (Wilkie and Finn, 1996). Therefore, attempt will be made in this study to map out the status of land use land cover of Ilorin between 1972 and 2001 with a view to detecting the land consumption rate and the changes that has taken place in this status particularly in the built-up land so as to predict possible changes that might take place in this status in the next 14 years using both Geographic Information System and Remote Sensing data. 1.2 Statement of the Problem Ilorin, the Kwara State, capital has witnessed remarkable expansion, growth and developmental activities such as building, road construction, deforestation and many other anthropogenic activities since its inception in 1967 just like many other state capitals in Nigeria. This has therefore resulted in increased land consumption and a modification and alterations in the status of her land use land cover over time without any detailed and comprehensive attempt (as provided by a Remote Sensing data and GIS) to evaluate this status as it changes over time with a view to detecting the land consumption rate and also make attempt to predict same and the possible changes that may occur in this status so that planners can have a basic tool for planning. It is therefore necessary for a study such as this to be carried out if Ilorin will avoid the associated problems of a growing and expanding city like many others in the world. 1.3 Justification for the Study Attempt has been made to document the growth of Ilorin in the past but that from an aerial photography (Olorunfemi, 1983). In recent times, the dynamics of Land use Land cover and particularly settlement expansion in the area requires a more powerful and sophisticated system such as GIS and Remote Sensing data which provides a general extensive synoptic coverage of large areas than area photography 1.4 Aim and Objectives 1.4.1 Aim The aim of this study is to produce a land use land cover map of Ilorin at different epochs in order to detect the changes that have taken place particularly in the built-up land and subsequently predict likely changes that might take place in the same over a given period. 1.4.2 Objectives The following specific objectives will be pursued in order to achieve the aim above. To create a land use land cover classification scheme To determine the trend, nature, rate, location and magnitude of land use land cover change. To forecast the future pattern of land use land cover in the area. To generate data on land consumption rate and land absorption coefficient  since more emphasis is placed on built-up land. To evaluate the socio economic implications of predicted change. 1.5 The Study Area The study area (Ilorin) is the capital of Kwara State. It is located on latitude 80 31 N and 40 35 E with an Area of about 100km square (Kwara State Diary1997). Being situated in the transitional zone; between the forest and the savanna region of Nigeria i.e. the North and the West coastal region, it therefore serves as a melting point between the northern and southern culture.(Oyebanji, 1993). Her geology consists of pre-Cambrian basement complex with an elevation which ranges between 273m to 333m in the West and 200m to 364m in the East. The landscape of the region (Ilorin) is relatively flat, this means it is located on a plain and is crested by two large rivers, the river Asa and Oyun which flows in North South direction divides the plain into two; Western and Eastern part (Oyebanji, 1993). The climate is humid tropical type and is characterized by wet and dry seasons (Ilorin Atlas 1981). The wet season begins towards the end of March and ends in October. A dry season in the town begins with the onset of tropical continental air mass commonly referred to as harmattan. This wind is usually predominant between the months of November and February (Olaniran 2002). The temperature is uniformly high throughout the year. The mean monthly temperature of the town for the period of 1991 2000 varies between 250 C and 29.50 C with the month of March having about 300C. Ilorin falls into the southern savanna zone. This zone is a transition between the high forest in the southern part of the country and the far North with woodland properties. (Osoba, 1980). Her vegetation is characterized by scattered tall tree shrubs of between the height of ten and twelve feet. Oyegun in 1993 described the vegetation to be predominantly covered by derived savannah found in East and West and are noted for their dry lowland rainforest vegetal cover. As noted by Oyegun in 1983, Ilorin is one of the fastest growing urban centers in Nigeria. Her rate of population growth is much higher than for other cities in the country (Oyegun, 1983). Ilorin city has grown in both population and areal extent at a fast pace since 1967 (Oyegun, 1983). The Enplan group (1977) puts the population at 400,000 which made it then the sixth largest town in Nigeria. The town had a population of 40, 990 in 1952 and 208, 546 in 1963 and was estimated as 474, 835 in 1982 (Oyegun, 1983). In 1984, the population was 480, 000 (Oyegun, 1985). This trend in population growth rate shows a rapid growth in population. The growth rate between 1952 and 1963 according to Oyebanji, 1983 is put at 16.0 which is higher than other cities in the country. The population as estimated by the 1991 population census was put at 570,000. 1.6 Definition of Terms (i) Remote sensing: Can be defined as any process whereby information is gathered about an object, area or phenomenon without being in contact with it. Given this rather general definition, the term has come to be associated more specifically with the gauging of interactions between earth surface materials and electromagnetic energy. (Idrisi 32 guide to GIS and Image processing, volume 1). (ii) Geographic Information system: A computer assisted system for the acquisition, storage, analysis and display of geographic data (Idrisi 32 guide to GIS and Image processing, volume 1). (iii) Land use: This is the manner in which human beings employ the land and its resources. (iv) Land cover: Implies the physical or natural state of the Eaths surface. CHAPTER TWO 2.1 LITERATURE REVIEW According to Meyer, 1999 every parcel of land on the Earths surface is unique in the cover it possesses. Land use and land cover are distinct yet closely linked characteristics of the Earths surface. The use to which we put land could be grazing, agriculture, urban development, logging, and mining among many others. While land cover categories could be cropland, forest, wetland, pasture, roads, urban areas among others. The term land cover originally referred to the kind and state of vegetation, such as forest or grass cover but it has broadened in subsequent usage to include other things such as human structures, soil type, biodiversity, surface and ground water (Meyer, 1995). Land use affects land cover and changes in land cover affect land use. A change in either however is not necessarily the product of the other. Changes in land cover by land use do not necessarily imply degradation of the land. However, many shifting land use patterns driven by a variety of social causes, result in land cover changes that affects biodiversity, water and radiation budgets, trace gas emissions and other processes that come together to affect climate and biosphere (Riebsame, Meyer, and Turner, 1994). Land cover can be altered by forces other than anthropogenic. Natural events such as weather, flooding, fire, climate fluctuations, and ecosystem dynamics may also initiate modifications upon land cover. Globally, land cover today is altered principally by direct human use: by agriculture and livestock raising, forest harvesting and management and urban and suburban construction and development. There are also incidental impacts on land cover from other human activities such as forest and lakes damaged by acid rain from fossil fuel combustion and crops near cities damaged by tropospheric ozone resulting from automobile exhaust (Meyer, 1995). Hence, in order to use land optimally, it is not only necessary to have the information on existing land use land cover but also the capability to monitor the dynamics of land use resulting out of both changing demands of increasing population and forces of nature acting to shape the landscape. Conventional ground methods of land use mapping are labor intensive, time consuming and are done relatively infrequently. These maps soon become outdated with the passage of time, particularly in a rapid changing environment. In fact according to Olorunfemi (1983), monitoring changes and time series analysis is quite difficult with traditional method of surveying. In recent years, satellite remote sensing techniques have been developed, which have proved to be of immense value for preparing accurate land use land cover maps and monitoring changes at regular intervals of time. In case of inaccessible region, this technique is perhaps the only method of obtaining the required data on a cost and time effective basis. A remote sensing device records response which is based on many characteristics of the land surface, including natural and artificial cover. An interpreter uses the element of tone, texture, pattern, shape, size, shadow, site and association to derive information about land cover. The generation of remotely sensed data/images by various types of sensor flown aboard different platforms at varying heights above the terrain and at different times of the day and the year does not lead to a simple classification system. It is often believed that no single classification could be used with all types of imagery and all scales. To date, the most successful attempt in developing a general purpose classification scheme compatible with remote sensing data has been by Anderson et al which is also referred to as USGS classification scheme. Other classification schemes available for use with remotely sensed data are basically modification of the above classification scheme. Ever since the launch of the first remote sensing satellite (Landsat-1) in 1972, land use land cover studies were carried out on different scales for different users. For instance, waste land mapping of India was carried out on 1:1 million scales by NRSA using 1980 82 landsat multi spectral scanner data. About 16.2% of waste lands were estimated based on the study. Xiaomei Y, and Rong Qing L.Q.Y in 1999 noted that information about change is necessary for updating land cover maps and the management of natural resources. The information may be obtained by visiting sites on the ground and or extracting it from remotely sensed data. Change detection is the process of identifying differences in the state of an object or phenomenon by observing it at different times (Singh, 1989). Change detection is an important process in monitoring and managing natural resources and urban development because it provides quantitative analysis of the spatial distribution of the population of interest. Macleod and Congation (1998) list four aspects of change detection which are important when monitoring natural resources: i. Detecting the changes that have occurred ii. Identifying the nature of the change iii. Measuring the area extent of the change iv. Assessing the spatial pattern of the change The basis of using remote sensing data for change detection is that changes in land cover result in changes in radiance values which can be remotely sensed. Techniques to perform change detection with satellite imagery have become numerous as a result of increasing versatility in manipulating digital data and increasing computer power. A wide variety of digital change detection techniques have been developed over the last two decades. Singh (1989) and Coppin Bauer (1996) summarize eleven different change detection algorithms that were found to be documented in the literature by 1995. These include: 1. Mono-temporal change delineation. 2. Delta or post classification comparisons. 3. Multidimensional temporal feature space analysis. 4. Composite analysis. 5. Image differencing. 6. Multitemporal linear data transformation. 7. Change vector analysis. 8. Image regression. 9. Multitemporal biomass index 10. Background subtraction. 11. Image ratioing In some instances, land use land cover change may result in environmental, social and economic impacts of greater damage than benefit to the area (Moshen A, 1999). Therefore data on land use change are of great importance to planners in monitoring the consequences of land use change on the area. Such data are of value to resources management and agencies that plan and assess land use patterns and in modeling and predicting future changes. Shosheng and Kutiel (1994) investigated the advantages of remote sensing techniques in relation to field surveys in providing a regional description of vegetation cover. The results of their research were used to produce four vegetation cover maps that provided new information on spatial and temporal distributions of vegetation in this area and allowed regional quantitative assessment of the vegetation cover. Arvind C. Pandy and M. S. Nathawat (2006) carried out a study on land use land cover mapping of Panchkula, Ambala and Yamunanger districts, Hangana State in India. They observed that the heterogeneous climate and physiographic conditions in these districts has resulted in the development of different land use land cover in these districts, an evaluation by digital analysis of satellite data indicates that majority of areas in these districts are used for agricultural purpose. The hilly regions exhibit fair development of reserved forests. It is inferred that land use land cover pattern in the area are generally controlled by agro climatic conditions, ground water potential and a host of other factors. It has been noted over time through series of studies that Landsat Thematic Mapper is adequate for general extensive synoptic coverage of large areas. As a result, this reduces the need for expensive and time consuming ground surveys conducted for validation of data. Generally, satellite imagery is able to provide more frequent data collection on a regular basis unlike aerial photographs which although may provide more geometrically accurate maps, is limited in respect to its extent of coverage and expensive; which means, it is not often used. In 1985, the U.S Geological Survey carried out a research program to produce 1:250,000 scale land cover maps for Alaska using Landsat MSS data (Fitz Patrick et al, 1987).The State of Maryland Health Resources Planning Commission also used Landsat TM data to create a land cover data set for inclusion in their Maryland Geographic Information (MAGI) database. All seven TM bands were used to produce a 21 class land cover map (EOSAT 1992). Also, in 1992, the Georgia Department of Natural Resources completed mapping the entire State of Georgia to identify and quantify wetlands and other land cover types using Landsat Thematic Mapper â„ ¢ data (ERDAS, 1992). The State of southern Carolina Lands Resources Conservation Commission developed a detailed land cover map composed of 19 classes from TM data (EOSAT, 1994). This mapping effort employed multi-temporal imagery as well as multi-spectral data during classification. An analysis of land use and land cover changes using the combination of MSS Landsat and land use map of Indonesia (Dimyati, 1995) reveals that land use land cover change were evaluated by using remote sensing to calculate the index of changes which was done by the superimposition of land use land cover images of 1972, 1984 and land use maps of 1990. This was done to analyze the pattern of change in the area, which was rather difficult with the traditional method of surveying as noted by Olorunfemi in 1983 when he was using aerial photographic approach to monitor urban land use in developing countries with Ilorin in Nigeria as the case study. Daniel et al, 2002 in their comparison of land use land cover change detection methods, made use of 5 methods viz; traditional post classification cross tabulation, cross correlation analysis, neural networks, knowledge based expert systems, and image segmentation and object oriented classification. A combination of direct T1 and T2 change detection as well as post classification analysis was employed. Nine land use land cover classes were selected for analysis. They observed that there are merits to each of the five methods examined, and that, at the point of their research, no single approach can solve the land use change detection problem. Also, Adeniyi and Omojola, (1999) in their land use land cover change evaluation in Sokoto Rima Basin of North Western Nigeria based on Archival Remote Sensing and GIS techniques, used aerial photographs, Landsat MSS, SPOT XS/Panchromatic image Transparency and Topographic map sheets to study changes in the two dams (Sokoto and Guronyo) between 1962 and 1986. The work revealed that land use land cover of both areas was unchanged before the construction while settlement alone covered most part of the area. However, during the post dam era, land use /land cover classes changed but with settlement still remaining the largest. CHAPTER THREE RESEARCH METHODOLOGY 3.1 Introduction The procedure adopted in this research work forms the basis for deriving statistics of land use dynamics and subsequently in the overall, the findings. 3.2 Data Acquired and Source For the study, Landsat satellite images of Kwara State were acquired for three Epochs; 1972, 1986 and 2001. Both 1972 and 1986 were obtained from Global Land Cover Facility (GLCF) an Earth Science Data Interface, while that of 2001 was obtained from National Space Research and Development Agency in Abuja (NASRDA). 0n both 2001 and 1986 images, a notable feature can be observed which is the Asa dam which was not yet constructed as of 1972. It is also important to state that Ilorin and its environs which were carved out using the local government boundary map and Nigerian Administrative map was also obtained from NASRDA. These were brought to Universal Transverse Marcator projection in zone 31. Table 3.1 Data Source 3.2.1 Geo-referencing Properties of the Images The geo-referencing properties of both 1986 2001 are the same while image thinning was applied to the 1972 imagery which has a resolution of 80m using a factor of two to modify its properties and resolution to conform to the other two has given below; Data type: rgb8 File type: binary Columns: 535 Rows: 552 Referencing system: utm-31 Reference units: m Unit distance: 1 Minimum X: 657046.848948 Maximum X: 687541.848948 Minimum Y: 921714.403281 Maximum Y: 953178.403281 Min Value: 0 Max Value: 215 Display Minimum: 0 Display Maximum: 215 Image thinning was carried out through contract; contract generalizes an image by reducing the number of rows and columns while simultaneously decreasing the cell resolution. Contraction may take place by pixel thinning or pixel aggregation with the contracting factors in X and Y being independently defined. With pixel thinning, every nth pixel is kept while the remaining is thrown away. 3.3 Software Used Basically, five software were used for this project viz; (a) ArcView 3.2a this was used for displaying and subsequent processing and enhancement of the image. It was also used for the carving out of Ilorin region from the whole Kwara State imagery using both the admin and local government maps. (b) ArcGIS This was also used to compliment the display and processing of the data (c) Idrisi32 This was used for the development of land use land cover classes and subsequently for change detection analysis of the study area. (d) Microsoft word was used basically for the presentation of the research. (e) Microsoft Excel was used in producing the bar graph. 3.4 Development of a Classification Scheme Based on the priori knowledge of the study area for over 20 years and a brief reconnaissance survey with additional information from previous research in the study area, a classification scheme was developed for the study area after Anderson et al (1967). The classification scheme developed gives a rather broad classification where the land use land cover was identified by a single digit. Table 3.2 Land use land cover classification scheme The classification scheme given in table 3.2 is a modification of Andersons in 1967 The definition of waste land as used in this research work denotes land without scrub, sandy areas, dry grasses, rocky areas and other human induced barren lands. 3.5 Limitation(s) in the Study There was a major limitation as a result of resolution difference. Landsat image of 1972 was acquired with the multi spectral scanner (MSS) which has a spatial resolution of 80 meters, whilst the images of 1986 and 2001 were acquired with Thematic Mapper â„ ¢ and Enhanced Thematic Mapper (ETM) respectively. These both have a spatial resolution of 30 meters. Although this limitation was corrected for through image thinning of the 1972, it still prevented its use for projecting into the future so as to have a consistent result. Apart from this, it produced an arbitrary classification of water body for the 1972 classification. 3.6 Methods of Data Analysis Six main methods of data analysis were adopted in this study. (i) Calculation of the Area in hectares of the resulting land use/land cover types for each study year and subsequently comparing the results. (ii) Markov Chain and Cellular Automata Analysis for predicting change (iii) Overlay Operations (iv) Image thinning (v) Maximum Likelihood Classification (vi) Land Consumption Rate and Absorption Coefficient The fist three methods above were used for identifying change in the land use types. Therefore, they have been combined in this study. The comparison of the land use land cover statistics assisted in identifying the percentage change, trend and rate of change between 1972 and 2001. In achieving this, the first task was to develop a table showing the area in hectares and the percentage change for each year (1972, 1986 and 2001) measured against each land use land cover type. Percentage change to determine the trend of change can then be calculated by dividing observed change by sum of changes multiplied by 100 (trend) percentage change = observed change * 100 Sum of change In obtaining annual rate of change, the percentage change is divided by 100 and multiplied by the number of study year 1972 1986 (14years) 1986 2001 (15years) Going by the second method (Markov Chain Analysis and Cellular Automata Analysis), Markov Chain Analysis is a convenient tool for modeling land use change when changes and processes in the landscape are difficult to describe. A Markovian process is one in which the future state of a system can be modeled purely on the basis of the immediately preceding state. Markovian chain analysis will describe land use change from one period to another and use this as the basis to project future changes. This is achieved by developing a transition probability matrix of land use change from time one to time two, which shows the nature of change while still serving as the basis for projecting to a later time period .The transition probability may be accurate on a per category basis, but there is no knowledge of the spatial distribution of occurrences within each land use category. Hence, Cellular Automata (CA) was used to add spatial character to the model. CA_Markov uses the output from the Markov Chain Analysis particularly Transition Area file to apply a contiguity filter to grow out land use from time two to a later time period. In essence, the CA will develop a spatially explicit weighting more heavily areas that proximate to existing land uses. This will ensure that land use change occurs proximate to existing like land use classes, and not wholly random. Overlay operations which is the last method of the three, identifies the actual location and magnitude of change although this was limited to the built-up land. Boolean logic was applied to the result through the reclass module of idrisi32 which assisted in mapping out separately areas of change for which magnitude was later calculated for. The Land consumption rate and absorption coefficient formula are give below; L.C.R = A P A = areal extent of the city in hectares P = population L.A.C = A2 A1 P2 P1 A1 and A2 are the areal extents (in hectares) for the early and later years, and P1 and P2 are population figure for the early and later years respectively (Yeates and Garner, 1976) L.C.R = A measure of compactness which indicates a progressive spatial expansion of a city. L.A.C = A measure of change in consumption of new urban land by each unit increase in urban population Both the 2001 and 2015 population figures were estimated from the 1991 and the estimated 2001 population figures of Ilorin respectively using the recommended National Population Commission (NPC) 2.1% growth rate as obtained from the 1963/1991 censuses. The first task to estimating the population figures was to multiply the growth rate by the census figures of Ilorin in both years (1991, 2001) while subsequently dividing same by 100. The result was then multiplied by the number of years being projected for, the result of which was then added to the base year population (1991, 2001). This is represented in the formula below; n = r/100 * Po (1) Pn = Po + (n * t) (2) Pn = estimated population (2001, 2015) Po = base year population (1991 2001 population figure) r = growth rate (2.1%) n = annual population growth t = number of years projecting for *The formula given for the population estimate was developed by the researcher In evaluating the socio economic implications of change, the effect of observed changes in the land use and land cover between 1972 and 2001 were used as major criteria. CHAPTER FOUR DATA ANALYSIS 4.0 Introduction The objective of this study forms the basis of all the analysis carried out in this chapter. The results are presented inform of maps, charts and statistical tables. They include the static, change and projected land use land cover of each class. 4.1 Land Use Land Cover Distribution The static land use land cover distribution for each study year as derived from the maps are presented in the table below LANDUSE/LAND COVER CATEGORIES 1972 1986 2001 AREA (Ha.)

Analysing The Power Crisis In Pakistan Environmental Sciences Essay

Energy production of a state is the premier index of its economic system. For a state to be economically stable and comfortable, it needs to hold sufficient energy at its disposal. No state can get high economic growing without bring forthing sufficient energy. Energy production reflects the industrial end product, transit and agricultural end product etc. restricting energy supply to an industry adversely affect its end product, ensuing in higher production cost, due to which many industries shutdown go forthing labor unemployed. In Pakistan, the electricity burden casting is an alarming issue. The rush of rising prices is due to energy deficit in the state. Number of people populating below poorness line is increasing due to unemployment and rising prices, both of which are the byproducts of energy crisis. From the last few old ages, Pakistan has been confronting an unprecedented energy crisis. The ground being that it ‘s energy substructure is non to the full developed, deficient and ill managed. Despite of important addition over the last few old ages in the disposable incomes, increasing usage of power intensive contraptions, urbanisation and industrialisation which has caused the power demand to outpace supply, no serious stairss have been made to put in new coevals capacity. Consequently, burden sloughing has been seen as the common phenomena in Pakistan. During the last 10 old ages, Pakistan ‘s power demand has risen by CAGR ( Compound Annual Growth Rate ) of 5.2 % , while supply has grown by merely 2.2 % ( Pakistan Power Sector, 2009 ) . Presently, state ‘s entire electricity demand stands at around 19,000MW. Demand supply shortfall ranges 2500-4500MW depending on peak clip and season, ensuing in burden sloughing of 4-8 hours day-to-day and 8-12 hours during th e extremum summer season. In Pakistan, entire installed coevals capacity is about 19,754MW ( Exhibit 1 ) , of which thermal is about 12,500MW i.e. 64 % of state ‘s entire coevals capacity, but the existent available capacity is limited to 16,500MW due to several grounds: power losingss during distribution stage due to poor-quality transmittal lines, electricity ‘s larceny, low works burden factors due to aging generators and hapless care at KESC and WAPDA workss, lessening in hydel coevals capableness due to fluctuation in the reservoir degrees particularly in winter season ensuing in the deficit of 2500MW to 4500MW depending on peak clip and season.Reasons of power crisis in Pakistan:Lack of large dikes in the state. Decline in hydro beginnings of energy ( a cheap resource ) and over trust on the expansive beginning of electricity i.e. Thermal based power coevals. Soon, oil and Gas-based thermic workss histories for 68 % of bring forthing capacity, hydroelectric workss for 30 % and atomic workss for merely 2 % ( Exhibit 2 ) . Rise in the oil and gas monetary values pushes the electricity duty really high. Consequently, leads to high coevals costs, which in bend adversely impact the economic system. Lack of strong political leading in Pakistan, to convert and safeguard the reserves of people on the building of one of the controversial dams- Kala Bagh Dam and other non-controversial dikes like Kohistan dike and Basha dike. To bridge the demand supply spread, around 5,000MW of IPPs and rental workss are expected to come online between 2009-2012 ( Pakistan Power Sector, 2009 ) . Though the state is endowed with huge hydel and coal based power potency, it is yet to to the full work these resources and cut down dependance on oil based coevals.Coal as an alternate energy resource:Coal is presently the universe ‘s fastest turning fuel around the Earth. Estimates show that around 40 % of universe power supply and 26 % of primary energy comes from the coal entirely. China, being the universe ‘s largest manufacturer of coal, fulfil 78 % its entire energy demands through coal which ranks it as the universe ‘s largest consumer as good. Similarly, USA stands at 2nd place in utilizing coal, 60 % of its energy demands comes coal. Many states like UK, USA, Germany, India, Indonesia and Australia have embarked upon the new coal based power workss. But, unluckily, Pakistan holding the 6th largest coal militias in the universe, with over 185 billion metric tons of proved coal militias, has non been successful in using coal as an alternate energy beginning. It is estimated that 100,000 MW of electricity could be generated from merely half of these resources, for 30 old ages, if exploited decently and the Energy contents of these resources are more than the energy contents of Saudi Arabia and Iran ‘s joint oil resources ( Pakistan ‘s Thar Coal Power Potential, 2008 ) .Why Coal can be an of import beginning of energy?Some of the grounds why coal is of import for Pakistan future energy state of affairs are as under: Current Energy Crisiss: Demand for electricity has outpaced its supply ; the state is presently confronting power deficits ranges between 4500 to 5,000 MW and it is expected that demand would transcend supply by beyond 5,500 MW. World-Renowned Companies Already Operating in Pakistan: Around twelve Independent Power Producers ( IPPs ) are runing in the power sector of the state. Predictable Multi-Year & A ; Long-run Duty: Typically, the authorities allows a long-run duty of 25 – 30 old ages with the power buyer. The IPPs, therefore, are non subjected to market hazard for their end product. The undertakings are expected to gain an attractive / competitory and stable return on investing. Abundant Coal Potential: Pakistan is blessed with big coal sedimentations peculiarly in its Sindh Province. The Thar brown coal militias, which are suited for power coevals, in the Province of Sindh are estimated to be about 175 billion metric tons.Research Aims:The chief aims of this research are, foremost to analyze the development of coal based power undertakings in Pakistan, learn about the deepness and comprehensiveness of this country and seek to foreground the key challenges and hazards associated with the investing in power sector of Pakistan in-terms of environmental restraints ( both locally and globally ) , security issues, authorities and regulative restraints etc. And secondly the research will take to analyse the power coevals sector of Pakistan utilizing Porter ‘s five forces analysis tool and place the function of Coal fired works in this sector. Such analysis of industrial profitableness will enable us to place the countries that need to be addressed to do the industry more attractive.Personal Claim:The grounds of taking this research are, foremost the research worker personally has a acute involvement in energy sector of Pakistan. Second, the demanding state of affairs in the energy sector of state, particularly power sector is the premier incentive to make research on the subject ‘Development of Coal Based Power Projects in Pakistan ‘ . And in conclusion, the chosen country is new one as non much has been done in the coal-based power coevals sector of Pakistan.Outline of the Undertaking:Chapter 2- Research Methodology3.1 IntroductionThis chapter will look at the necessary research methods required to transport out the research in order to accomplish the research aims. In order to accomplish this I have looked at the counsel given in ( Saunders et al 2003 ) .3.2 Aims and JustificationThe aim of this research methodological analysis is to place the agencies of roll uping valid and dependable primary and secondary informations. It analyses all facets of the research methodological analysis.3.3 Research ApproachInductive and deductive are two types of attacks that can be used whilst carry oning the research ( Saunders et al 2003 ) . This research will utilize the deductive attack where the findings of the research will be used to look into the literature sing the fiscal state of affairs of Jessops. The deductive attack will let roll uping quantitative informations, and will besides help in making a hypothesis and a research scheme to prove the hypothesis. As in the instance of this survey fiscal theoretical accounts will be used. The inductive attack is where, from the findings and analysis a theory is proposed ( Saunders et Al, 2003 ) , therefore this attack will be used to prove the hereafter of Jessops.3.4 Research DoctrineSaunders ( et al 2003 ) , indicates there are three types of research doctrines that are interpretivism, positivism, and pragmatism. Positivism is where ‘the theory generates a hypothesis that can be tested and thereby will let account of Torahs to be assessed ‘ ( Bryman & A ; Bell, 2007 ) . The function of this research is to prove the theories from the literature, hence positivism will be used. Positivism besides strongly links with the deductive attack that will be used. Interpretivism considers that the universe of concern is excessively complex and is ever changing where definite Torahs can non be defined. Hence this method is irrelevant for this survey.3.5 Research StrategyI will choose the study method for my research. I will utilize a questionnaire which will let more in depth comparings. It is besides seen good to utilize this method as it is easy understood by people, other benefits of utilizing such a method are that it is most efficient in clip, cost, and flexibleness and will let consequences to be analysed with easiness, which is extremely applicable for this survey. The usage of a study will besides supply greater response rates from participants ( Bryman & A ; Bell, 2007 ) . The questionnaire will let me to place from the directors and fiscal departmental workers at Jessops to why gross revenues at Jessop have plummeted and will supply grounds for premises to look at the hereafter of Jessops.3.6 Data Collection and Sample3.6.1 Sample The sample size will be in entire 30 participants selected indiscriminately. All participants will be employees of Jessops, as this will let the research worker to derive valued informations because employees will hold a better penetration into the company. However the response was non a coveted 1 as merely 17 participants completed the questionnaire. However due to clip restraints non much could be done to get the better of this issue, even though the position of 17 participants was still considered of import due to their functions within the company. 3.6.2 Primary Data This research uses both primary and secondary informations. Primary research as mentioned above we be collected via questionnaires. The questionnaire will be aimed at current employees of Jessops of who are shop directors and the remainder of who work within the fiscal section. This is a critical sample for the research as the positions and remarks of the proposed participants will supply important penetration into what is go oning within Jessops, and will assist analyze their fiscal public presentation. 3.6.3 Secondary Data Secondary informations will be taken from literature ( i.e. diaries, books, articles etc. ) ; nevertheless another facet of secondary research will be company histories and studies. This will be critical as utilizing company histories and studies will let the research worker to to the full analyze the state of affairs of Jessops and will assist organize a footing in the hereafter of Jessops. The histories will besides enable the research worker to utilize the fiscal theoretical accounts such as Altman ‘s z-score theoretical account.3.7 Questionnaire DesignThe questionnaire is seen to be an of import tool for research harmonizing to ( Naftali, 2001 ) , therefore the questionnaire needs to be precise, accurate and good designed. Naftali ( 2001 ) was used as guidelines for the design of the questionnaire. The questionnaire was designed to achieve relevant informations required for the primary aims of this research. Hence the questionnaire was designed to maintain inquiries simple and to the point to have the coveted consequences. A transcript of the questionnaire can be viewed in Appendix B.3.8 Data AnalysisThe information from primary and secondary research will be analysed in many ways. The quantitative consequences from the primary research will be analysed utilizing Excel, whereas SPSS will besides be used to place relationships and correlativities between responses of participants to supply a clearer position on the research. The above methods including secondary informations will be presented diagrammatically where necessary utilizing graphs, tabular arraies and charts.3.9 Reliability and ValidityThe information was collected after with planning and due attention. The informations collected can be considered dependable hence the specified beginning of information was chosen. However the primary informations to an extent may non be dependable as participants may confabulate replies with each other. The secondary research can be identified as dependable and valid as all information was collected via company histories and studies.3.10 Research RestrictionsTime was a cardinal restriction within this survey as designing and administering the questionnaire ‘s required a batch of clip. Receiving all consequences was besides clip devouring as it did non give a clear thought on how many consequences would be attained. A longer clip frame would hold allowed countering this job.3.11 Research Ethical motivesAll research was conducted within the Lcmit University Research Ethics guidelines. The moralss declaration can be viewed in Appendix A. All participants opted by pick to take portion in finishing questionnaires and participant individualities were kept anon. to the highest degree.3.12 Alternate MethodsA possible method of deriving primary research that could hold been used was an interview. The interview method would hold allowed for elaborate analysis to inquiries and more preci se responses from the interviewee. The research worker did non utilize this method due to clip restraints, and besides the research worker felt the usage of interviews may hold resulted in more colored consequences.3.13 DrumheadThis chapter takes into consideration the methodological analysis that will be conducted in order to transport out the research for this survey. The following chapter will exemplify the existent findings of the primary and secondary research.Literature reappraisal:Introduction:Pakistan is blessed with big coal sedimentations peculiarly in its Sindh Province. The entire coal resources of Pakistan are over 185 billion metric tons out of which about184 billion metric tons exist in Sindh entirely ( Exhibit 3 ) . The coal sedimentations of Sindh are of Lignite which is suited for power coevals. The reported one-year coal production in 2003 was around 3.3 million tones ( Exhibit 4 ) . The immense coal potency of Pakistan can good be utilized in power coevals for su stainable socio-economic development of the state.Constitutional Position on CoalCoal is considered as mineral and under the ‘Constitution of Pakistan ( 1973 ) ‘ mineral is a provincial topic. The Provincial Governments are responsible for the development of coal. The ‘National Mineral Policy 1995 ( revised in 2002 ) ‘ focal points all activities and determination at Provincial degree while the Federation would supply needed support and advice to the Provinces to take up the challenge of accomplishing benefits from the development of coal resources. Some of the Fiscal & A ; Financial Incentives for Coal Development are discussed in Appendix 2.Why Coal neglected so far?Pakistan ‘s power sector is chiefly dependent on the thermal based power workss. Thermal coevals dissolution shows that gas fuel histories for 55 % of thermal-based bring forthing capacity, furnace Oil for 44 % and Diesel Oil for merely 1 % and Coal 0 % ( Exhibit 2 ) . It is a known fact t hat Pakistan has the 6th universe largest coal militias, but unluckily, coal has non been developed for power coevals. The research conducted by Tipoo Sultan ( 2008 ) indicates that in the past, many powerful transnational oil companies and trusts have been involved in understating the use of coal as an energy beginning in the development states, as they do non desire to see coal as the replacing of oil that they sell. Miss-perceptions about the coal public-service corporation have affected the authorities policies. The quality of coal and big sum of capital demand has make coal addition less importance in the development precedences. Second, the authorities has been failed to pull the foreign investors to put in coal based power undertakings. Few of the investors after being confronting immense losingss were forced by the authorities to discontinue their undertakings. For case, Zafar Bhutta ( 2008 ) , in his article â€Å" Sino Coal, Engro Pakistan to work on Thar coal undertaking † , reported that â€Å" Chinese Company, Shenhua was ready to construct the integrated excavation and power coevals composite at a guaranteed power duty of 5.75cents per unit but NEPRA refused to pay more than 5.34 cents. Chinese company packed its operations in Pakistan and went back to China go forthing no good mark for the investors interested in coal based power workss. † There are other factors, besides those stated above, that has added to the investor ‘s reluctance in the development of Pakistan coal resources. These are as follows: The foremost barrier to foreign investing is the provincial liberty over the coal excavation. A recent illustration indicated by Aftab Channa ( 2010 ) in his article: â€Å" Power workss at Thar Coal: Czech Republic unlikely to put 500 million euros † , is the WTC group of Czech democracy who are interested in puting atleast 500 million Euros at Thar Coal for coal-burning power workss of 300 to 600 MW but unluckily the response of Sindh authorities is non overpowering ‘yet ‘ . The Technical Director, WTC Group, Karel Galuska forwarded a missive to Secretary Coal and Energy Development Department Aijaz Khan on June 21, 2010 stating that: â€Å" We would wish to inform you that therefore far we have non received any information from you. We are get downing to believe that the authorities of Sindh is non taking ‘coal ‘ as a serious plus for its state and for work outing energy crisis in Pakistan. â€Å" ( Karel Galuska ) . Lack of needed substructure like roads, railroad lines, communicating webs, H2O supply, life support systems, community services and etc The policies of the authorities are non consistent. They alter with the changed authorities. There is Political uncertainness in the state. The Law and order state of affairs in the state was non favorable and still its a questionable fact. absence of modern coal excavation proficient expertness deficient fundss There is a quality concerns as good with the coal deposits found at Thar.Current SituationPakistan is a coal-rich state, but, unluckily, coal has non been developed for power coevals for more than three decennaries due to miss of substructure, deficient funding and absence of modern coal excavation proficient expertness. The Government is now seeking to advance and ease private investors in developing and advancing autochthonal coal for power coevals. The demand/supply projection indicates that power deficits appeared from the twelvemonth 2006, and has increased to 4,500 MW in the twelvemonth 2010 will increase farther if no steps are taken to convey in new capacity. In order to turn to these deficits, the GOP announced Power Policy 2002 which provided a set of inducements to pull the much needed investing in power coevals. The cardinal points of the new policy are International Competitive Bidding ( ICB ) and an accent on puting up power undertakings based on autochthonal fuel resources such as coal, hydal power and renewable energies.General Regulations sing coal-based Power Undertakings:The power policy 2002 lays major accent on the development of power undertakings based on autochthonal coal. Merely Provincial Governments are authorized to allow rentals and licences for coal prospecting and coal excavation to Private Sector and Public Sector companies or organisations. There is no function of Federal Government and Public Sect or to allow rentals and licences for coal excavation. Coal is considered as mineral and mineral is a Provincial Subject harmonizing to the Constitution of Pakistan. There was a job that when prospective investors got a excavation rental and had signed a MoU with the several provincial authorities, so such unasked natural site had to be considered. On designation of a natural site by the provincial governments, PPIB advertises coal natural sites for seeking proposals from investors ( see appendix-2 ) . PPIB can besides transport out International Competitive Bidding ( ICB ) after acquiring a bankable feasibleness survey completed. The GOP guarantees the footings and conditions of executed understandings, i.e. IA, PPA, including payment footings, which are maintained for the continuance of the Agreements for undertakings. The coal power bring forthing companies would be allowed to import works, equipment and machinery non manufactured locally, at concessionary rates. The power companies would besides be wholly exempted from the payment of income revenue enhancement and keep backing revenue enhancement on imports. In order to advance indigenization, the local technology industry will be encouraged to organize joint ventures with foreign companies to develop incorporate undertakings of coal-mine and coal-burning power workss with a cumulative capacity of at least 2000 MW by the twelvemonth 2015. The inducements for puting in coal based power workss in Pakistan are given in Appendix-2.How to continue frontward with coal-based power workss?The ordinance and processing of the applications by investors takes topographic point at the provincial every bit good as federal degrees. The measure by measure process is given in Appendix-3 ( Courtesy: PPIB ) and subsequent appendices.Requests for Proposal ( RFP )It is mentioned that the Request for Proposal ( RFP ) for an autochthonal coal-burning undertaking with capacity above 50 MW will be for an incorporate coal excavation and/or power coevals works composite. The particulars required for a undertaking offered for competitory command in a typical RFP ar e mentioned in appendix-4.Feasibility StudyFor integrated coal-mine and power coevals workss, the feasibleness survey will cover all facets of coal excavation and power coevals, including, but non limited to, coal militias, mine ability, hazards involved in excavation, legal facets of excavation etc. , besides storage/transportation of coal to the power works, operations of the power works on coal, necessary inside informations about the power coevals works itself and, above all, the commercial viability of the undertaking. The feasibleness survey may or may non propose a ‘Coal Supply Agreement ( CSA ) ‘ in such instance. For a stand-alone coal-based power coevals works, the excavation subdivision would non be covered in item. However, handiness of a sufficient and dependable coal supply for power coevals would be considered, besides other necessary facets. The feasibleness survey may necessitate a CSA even if the coal provider is sister concern of the power generator. S ome farther demands are as mentioned in Appendix-6.Evaluation of CommandsThe process is given in Appendix-6. PPIB will reserve the right to reject any or all commands without delegating ground therefore, and will non presume any liabilities or claims for compensation in connexion therewith. Once the command is accepted and tariff approved by PPIB, the successful bidder will be issued an LOS by PPIB against bringing of a Performance Guarantee ( PG ) in favour of PPIB, in the needed sum valid up to three months beyond the Financial Closing day of the month specified in the LOS and upon payment of the cost of the feasibleness survey to PPIB. Further stairss to be taken are given in Appendix-8.Power Duty:The development of a coalmine, constitution of coal-burning power works and transit installations to provide dependable coal for the incorporate undertaking of power works and mine, require significant investing. These disbursals are to be accounted for in the power duty in the signifie r of capacity and energy charges. The duty will be denominated in Pakistan Rupees Bidders will be asked to cite their duty in two parts: ( 1 ) Energy Purchase Price ( EPP ) and ( 2 ) Capacity Purchase Price ( CPP ) The RFP may stipulate the maximal per centum of overall duty for the capacity constituent The CPP will be paid provided the works is available for dispatched to criterions specified in the PPA. The EPP will be paid upon the sum of kWh of energy dispatched In order to guarantee sustained involvement of the patron during the full life of the undertaking, the amount of the EPP and non-debt related CPP ( computed on a kWh footing at the mention works factor specified in the RFP ) will stay changeless or increase over clip. The debt-related CPP watercourse may fit the loan refund watercourseEnvironmental issues and Pakistan ‘s coal based developmentFossil fuel power coevals is non environment friendly as its CO2 emanation contributes to air pollution and it has been connected with planetary heating. Soon, the emanation of gases like C dioxide, S dioxide, and N oxides, into the air is the lone pollution caused from coal-burning power workss. The chief ground for increasing usage of coal burning is because it is inexpensive and it plays major function in carry throughing energy demands. Since 1950, planetary concern over impact of nursery gasses has emerged into international ordinances for restricting CO2 emanation in ambiance. First international regulation pact in this respect was Kyoto protocol ( 1997 ) . It obliges 37 industrialised states to run into binding CO2 emanations marks. Footings of the dainty are such that globally there is bound to how much CO2 can be produced, and some states produce more CO2 than others. Those who use more than their bound can borrow C credits from states non utilizing their quota. Interestingly, USA recognizes the pact but it has non agreed to follow with the C emanation marks although it is a major dodo fuel consumer. Carbon recognition system under Kyoto Protocol requires single corporations to countervail their C emanation by either retrofitting the works to cut down its C emanations or put ining carbon-capture equipment to cut its emanations by a million ton, or purchase carbon beginnings from a C bargainer for a undertaking in a underdeveloped state like Pakistan. ( Exhibit 5 ) The issue of emanations control has to be decently addressed under Kyoto protocol. In the longer term one must besides maintain in head that CO2 extenuation initiatives down the route may go mandatary for the states like Pakistan excessively. This will add to the cost of coal power coevals as has happened in the developed universe. One must maintain in head that a typical power coal works generates 3 million dozenss of CO2 or 17 dozenss of C per megawatt and draws approximately 2.3 billion gallons of H2O per annum from nearby beginning while on land, whereas Sind which has 90 % of Pakistan ‘s coal modesty is earnestly lacking in the supply of H2O ; produces quicksilver which non merely renders H2O useless for human ingestion but besides for irrigation intent as good. Area of chance is that C beginning market is existent and major Bankss involved are involved in it. Entire C beginning market is about $ 6 billion ( Jan 2010 ) , and it is projected to transcend 50 billion dollars after the US joins C trading so Pakistan can profit from any C recognition potency in different industries. In 2008 Pak-Arab Fertilizers ( Pvt. ) Ltd. , earned $ 13 million through selling CER ( The Nation newspaper ) . Islamabad is establishing C recognition undertakings from beginnings runing from landfills to vehicles. Asiatic states have several CDM undertakings registeredChapter-3Proposed Strategy continue with the development of coal-based power undertakingsScheme is driven by lacks and chances inherent in a peculiar industry. To unearth these two variables the industry has to be scrutinized utilizing a scientifically established tool. In our instance we will be utilizing Porter ‘s five forces to analyse the power coevals sector of Pakistan and place the functio n of Coal fired workss in this sector. Such analysis of industrial profitableness will enable us to place the countries that need to be addressed to do the industry more attractive.What is an Ideal Industry?An ideal industry would be one where ; The dialogue power with buyer/suppliers is low. The competition is minimum. Substitutes do non be or even if they exist they are excessively expensive to move as replacements. Entry barriers are comparatively low. It will be interesting to see if the power sector of Pakistan has all the above mentioned factors to do it attractive for investors.Power Sector of Pakistan ( Analysis utilizing Porter ‘s Five Forces Model )Buyer PowerBefore we embark upon discoursing the magnitude of the power held by the purchasers in the power sector it is of import to first place the purchasers in the industry. Chiefly the purchasers of the power in Pakistan are authorities organisations such as WAPDA which has sole distribution rights of electricity in the state. WAPDA, KESC etc service as the jobbers between the concluding consumer and the power manufacturers. This means that though there are merely a few purchasers and logically talking the lower the figure of purchasers the greater their power but kineticss of the industry in Pakistan are such that the purchaser is vulnerable and power providers are at a much more powerful place. To authenticate this statement we need to look into the per unit monetary value addition of electricity in Pakistan over the last few old ages.Electricity Price InflationThe past four old ages data indicate that there has been a stable addition of 13 % -14 % in electricity duties on one-year footing. Two grounds seem to confirm this rising prices in duties ;Demand/Supply DynamicsOver the past few old ages the state has been bring forthing power at a steady rate without taking into consideration the one-year population growing rate of 2 % . This has led to a 4000MW deficit of electricity in 2009-10. ( Exhibit 7 ) This shortage in supply has led to a demand supply instability taking to hyperbolic duties. Similarly we may see the same scenario from a different angle. Harmonizing to the per capita power ingestion rates Pakistan ‘s rate is 464KWh which is 41 % lower than Asia and significantly lower than the mean rates of the universe. ( Exhibit 8 ) . The low per capita power ingestion rate is due to the fact that installed power is less than the needed power.Raw Material Price InflationThe 2nd most important ground for the uninterrupted rush in electricity monetary values has been increase in oil monetary values. ( Exhibit 9 ) . The above chart indicates that most of the power workss in Pakistan are thermic based and fueled by furnace oil. Similarly if we look at the tendency of furnace oil monetary values in Pakistan we see that the monetary values have been systematically on the rise. This addition in monetary values is reflected in the hyperbolic duties that are being charged by the pow er manufacturers. ( Exhibit 10 )Deductions of Low Buyer PowerMade the industry attractive for new investors. High costs to consumers have made the authorities incentives the power sector so as to pull to more investors. ( Appendix-9 ) New window of chances for workss based alternate fuels ( such as coal ) so that the consumer gets cheaper electricity. Since a larger ball of electricity is being used by industrial and commercial units the burden casting entirely in 2009 led to $ 210 billion losingss to the national economic system. ( Exhibit 11 )Barriers to EntryBarriers to entry be given to do the industry unattractive for new entrants. In stead of the power crisis being presently faced by Pakistan the authorities in its capacity should and it must get the better of any entry barriers to the industry. Three barriers to entry have been identified ;Capital Intensive SectorThe authorities is concentrating on promoting power workss that are based on alternate fuels such as coal. But the sum of capital required to put up a coal fired works is really high. ( Exhibit 11 ) Investors may be encouraged to put in capital intensive undertakings by supplying them with inexpensive entree to capital and high rate of return.Government RegulationsThe whole procedure of using for a coal rental country and so acquiring an blessing from the relevant governments for puting up a works is highly boring and clip consuming. The patrons have to take blessing from both provincial ( in instance of renting mine country ) and federal authorities ( LOI, LOS, PPA, IA etc ) . The authorities can cut down the elaboratenesss in application procedure by giving authorization to one organisation which could be PPIB to function as a interface between the authorities and the investors.Infrastructural Issues ( Coal power workss )Coal excavation sector of Pakistan is extremely developing. Right of manner to most mines is under developed. Most countries that have been advertised by PPIB are devoid of H2O. To get the better of these issues the authorities has to work manus in manus with the prospective investors. Some remedial actions that can be taken by both the parties are ; Use belowground H2O as a beginning of H2O. The authorities should supply grapevines to transport the H2O to the sites. Increased use of belowground H2O will do the excavation of coal easier. Bucket wheel excavators alternatively of shovels and trucks could be used to retain higher net incomes and achieve better efficiencies. ( Appendix-10 )3- Intensity of RivalrySome factors that contribute to the strength of competition have been listed in Exhibit-5. By analysing the nature of the power sector we see that about all the factors that must be at that place in an industry with intense competition are non applicable to the power sector of Pakistan. One major lending factor that reduces the competition is the intensely regulated environment of the power sector.4- Supplier Power ( Coal )As mentioned before since the authorities is be aftering on working alternate beginnings of energy to supply cheaper electricity to the consumer ; so an in depth analysis of coal supply in the state reveals the fact that about 185 billion dozenss of coal militias are still untapped ( Exhibit-1 ) . This is adequate coal to supply 100,000 MW of energy for 300 old ages. Since there are barely any constituted coal houses in Pakistan that can function as exclusive providers of coal to the power workss, therefore most of the workss will hold to backward integrate in to char excavation. Soon there are certain hurdlings in back ward integrating as the ordinances refering to char excavation have yet to be established by the authorities of Pakistan. Though our suggestion would be to border ordinances that encourage back ward integrating.5- Substitutes ( w.r.t Coal )There are several utility beginnings of energy available to char, nevertheless most of them require greater capital outgo as compared to char based power undertakings ( Exhibit-6 ) . Handiness of the replacements is besides limited as compared to the handiness of coal therefore doing the replacements unattractive for investings.

Descartes And Nietzsche s View On The Mind And Body...

â€Å"I am thinking, therefore I exist† (Discourse on Method 15) In his Discourse on Method, Rene Descartes offers the above proposition, in response to the radical doubt (Discourse on Method 15)This implies that, even the human ability to doubt one’s existence is proof that humans are thinking beings, and therefore must exist in the universe, despite all else. Nietzsche has written in contrast to this statement, discussing the contradictions and assumptions surrounding the proposition. Stemming from this initial premise, both Descartes and Nietzsche go on to discuss the mind/body problem. Descartes argues for the separation of mind and body, while Nietzsche offers a premise based on a deep connection between the two. I seek to compare the writings of both philosophers, and explore holes in judgment and scope on the part of Descartes, and prove as to why Nietzsche’s discussions are superior of the two. Descartes discusses the existence of the human mind as a separate entity from the human body, including the a passage confirming his own existence as nothing but a thinking entity, in his writing Principles of Philosophy (I. 63-65). Following his rejection of all knowledge, in order to divide what was false from what could be proven, Descartes strives to prove the existence of his own mind, as a basis from which to prove the existence of the rest of the universe.

Art As A Vehicle For Social Commentary - 1410 Words

Art became a vehicle for social commentary in the 1900’s largely due to the work of Andy Warhol. It was during a time where media were playing a huge role in the desensitising of violence, in encouraging the consumerism mind state, and in its treatment of celebrities. Warhol brought his own pop art style of art making to these ideas, creating works of art that make strong comments about the world he was living in. The paintings of his that I will be discussing alongside these ideas are; Campbell’s Soup Cans, Marilyn Diptych, Race Riot and Little Electric Chairs. Andy Warhol made many works opposing the violence culture in America. His many versions of Race Riot paintings were based on photographs taken by Charles Moore. Shot during a riot in Alabama, 1963, at a time when racial conflict was reaching a climax, with the arrest of political activist Martin Luther King Jr. In the Race Riot paintings, Warhol showcases scenes of horror that have been published, and removes them from their context of an informative source, such as newspapers. By multiplying and altering these raw images, and presenting them in a new light, Warhol successfully changes how the audience perceives these images. Although they are sometimes graphic, disturbing images, seeing them repeated and multiplied reduces the shock of the violence . In a way these works allude to societies’ desensitising to violence, due to media’s constant stream of violent and graphic material.
