The world's population increased drastically and forced people to migrate from rural area to major cities in search of basic amenities. The majority of the World's population are already living in the major cities and it is continuously increasing. The increase in population forced the major cities to expand. Expansion of cities acclaimed more unplanned settlement that leads unplanned growth. This is a global phenomenon that has a direct impact on natural resources. It is the biggest challenge for urban planners to achieve sustainable development. Developing countries like India, where the population is increasing at an alarming pace, require more attention towards this problem. In this study, an attempt has been made to measure and monitor urban sprawl in Jaipur (Capital, State of Rajasthan, India). Built-up area with corresponding population has been analysed over a period of 41 years (1972-2013). Remotely sensed images of 1972-2013 (MSS, TM and ETM+) have been classified using Supervised Maximum Likelihood Classification (MLC) for digital image processing. Shannon's entropy has been used to quantify the degree of urban sprawl, and eight landscape metrics have also been used to quantify urban sprawl and its pattern.

Abstract Development is an innate manifestation on earth. It is not even surprising that the world has developed tremendously over the past decade considering the development in the previous decades. That is, development precipitates development. Therefore, even though everybody can see what risks it brings to the earth, we cannot simply restrain it. Of course, we cannot restrain it. The bottomline is that we have no choice but to be part of the development and be one of those who assist in the ever spontaneous development by trying to minimize its unwanted effects to the planet and its inhabitantants, the humans. Even looking at the ‘development’ from one’s own microcosm, we can perceive that as we go through life and gain some of what this world can offer, we produce tons and tons of wastes. These wastes, which are naturally not part of the earth, pollute and disrupt the natural processes of the planet. It is also simple to notice that the fundamental cause of the depletion of the earth’s natural resources was definitely proportional to the increase in population and to the development itself. Here lies one of the underlying global problems at hand aside from poverty, hunger, low access to education, and other socio-anthropological issues we have, this is the issue on natural resources depletion. Even to worldleaders from well-developed countries can recognize that they will also be the ones at the receiving end of this problem. It is basic that living organisms rely on their environment or the abiotic factors, to live sustainably. Considering these problems, the United Nations, with the worldleaders as its composition, has come up with strategies that advocate development while keeping the earth’s natural resources from depletion or the earth’s natural processes from disruption. This advocacy is called Sustainable Development. Sustainable Development is the development that meets the need of the present generation without compromising the ability of the next generation to meet their own needs. It is, at its core, an advocacy for futurism and the next generation. Sustainable Development is primarily anchored with the case of the “carrying capacity” of the planet Earth. It was already implied by several natural scientists as well as social scientists that indeed the Planet Earth increasingly finds it hard to sustain the needs of the human races because of overpopulation. These things result to poverty and hunger around the world. On the otherhand, it is increasing implied that most of the Natural Resources of the planet goes to the well-developed countries, leaving the developing and underdeveloped countries with meager resources. This further increases cases of hunger and poverty. Although it is deceptive that the call for a sustainable development should take its toll on the countries with bigger economy since they consume the most and pollute the most, it is very definite that there should be a much more intensive application in developing countries since we are just about to experience what the rest of the developed countries have already experienced. More importantly, developing countries should advocate Sustainable Development since it is a common knowledge that even if they contribute least to the causes of natural resource depletion and disruption of natural processes, they are the ones who suffer most from the devastating effects of unsustainable development. As citizens of the Republic of the Philippines, we are one of those who suffer most.
