Though no single answer exists, there are some arguments to sketch an answer. Undoubtedly the inherent complexity of the desertification phenomenon hampers almost every phase of the sequence leading to the mitigation or control of an environmental problem i. These advances show that vegetation dynamics in drylands may remain seemingly unaffected by an increase in land use pressure until there is a sudden shift to a lower-productivity stable state, with stochastic climate events, such as severe droughts, acting as triggers.
Additionally, incomplete or inadequate scientific knowledge, together with the urgent need of integrative solutions for the Sahelian drama, may have driven actors to resort to the first workable options, leading to erroneous regulations at that time. However, regulations of this kind are not dependent on scientific knowledge alone but also on political pressure mechanisms. Thus an explanation of the failure to achieve sound regulation needs to consider political issues as well.
National governments benefit not only from foreign financial aid but also from the use of desertification as the basis for severely repressive social control. International donors and institutions find the problem of desertification a reason unto itself for their involvement, whereas scientists may highlight the global nature and severity of the desertification problem as a means to obtain research funds.
On the contrary, the bottom-up approaches promoted by the populist discourse do not fit the terms and conditions of bilateral and multilateral funding and instead stress the principles of participation and decentralization. It is apparent that the progress achieved in our comprehension of desertification has not been matched by an improvement in the regulations aimed at mitigating its consequences.
Future contributions to the solution of the desertification problem require the synthesis of recent social and ecological advances into a new synthetic framework that overcomes the constraints upon the solutions imposed by the GEM and populist discourses. Social scientists hope that a new desertification paradigm—that is, the dryland development paradigm, which represents a convergence of insights from both discourses—is emerging.

Farmland to Deserts A lot of arable land is increasingly turning into deserts nowadays. Many reasons are attributed to this tendency. According to UNESCO in a new technique to halt desert encroachment, taking a close look at China for instance, the rate of desertification has risen to world environmental organizations concern.
This is because the rate of farmland deterioration has risen in china to km2 per year. Among the causes of farmland deterioration to deserts are: Intensive agriculture; overproduction from the same land is causing arable farmlands to convert to deserts as a result of nutrients in the soil being exhausted and not being replenished.
The ultimate result has been the farmland becoming unproductive thus explaining desertification is on the increase. Population pressure; UNESCO points out one this as one of the causes and effects of desert encroachment, too many people in a small piece of land results…… [Read More]. Water Legislation Origins of Environmental. The Leblanc alkali production processes were especially pernicious, but they followed along the lines of previous industrial processes.
In other words, the first British environmental legislation was a response not so much to a qualitative change in industrial processes and their environmental impact but more to a quantitative increase in sources of pollution that had up to that point been if only barely tolerable. Legislation Arising From Public Anger At the center of the first British environmental legislation was the Leblanc process, an industrial process that produced of soda ash which is chemically sodium carbonate that came into use in the first decades of the 19th century.
Named after its inventor, Nicolas Leblanc, it replaced an older process in which soda ash had been produced from wood ash. However, as the availability of wood ash declined because of deforestation, a process that was occuring both in Great Britain and across…… [Read More]. Multicriteria Analysis Model of Land.

Water in Sub-Saharan Africa is of special interest because of my background but water is a fascinating issue in general, one that I think will play an increasingly large role in the 21st century, as the effects of population growth and climate change bring about significant changes to our water usage and availability.
A lack of water in particular has a substantial destabilizing effect. Water as a social issue combines a lot of different elements. As an issue, water sits at the intersection of social justice, politics, economics and agriculture are all areas weather.
This is probably because water is so essential to human life. We drink it, we use in for domestic purposes, agricultural, industrial, transportation. Yet clean water is not always easy to come by. Some feel that access to clean water is a human right.

Marketing Water Fans, India Industry outlook The market in India for water fans or misting fans as they are also called is problematical at best.
Without doubt, the climate except in the northern mountains is hot; the problem is, it is also quite humid. Still, the Indian people have been looking for ways to stay cool for centuries. It was India that gave the world the slatted shutter; when air comes in through small spaces as in shutters, adopted in the American South before air conditioning, or in lattice-work walls as in parts of India , it is cooled. Still, they did not develop a cooling system like that of that ancient omans, which did use water running through channels to create condensation.
The reason, of course, is the problem of water quality. While industrial pollution has now added immeasurably to the water quality problems in India, the sluggish flow of…… [Read More]. Technology and Global Exosystem.
Technology and Global Ecosystem An Analysis of the Implications of Technology and the Global Ecosystem The 21st century promises to usher in innovations in technology that cannot yet be imagined, and the advancements to date have provided many in the world with unprecedented standards of living.
Improved methods of transportation and communication, combined with more leisure time than ever in which to spend it has resulted in many people developing a keen appreciation for technology and what it promises for mankind; an unfortunate concomitant of these innovations in many parts of the world, though, has been an intensive assault on the globe's ecosystem in an effort to bring emerging nations into line with the productivity being experienced in the developed nations of the world.

According to owett , despite the growing body of research into the history and purpose of international public unions, the authorities have not reached a consensus on their classification; however, the constitutional developments and innovations made by the public unions are important considerations for policymakers today because they presaged those made by contemporary inter-governmental organizations owett, In the first instance, the trend towards permanence of association was distinct, no matter whether…… [Read More].

Country of Sudan Dependency Theory. However, in the case of Sudan, it may be said that none of the above theories applies. This is largely due to the fact that there are specific internal factors which determine the orientation of the economy in a certain direction.
These are most of the times related to the historical evolution of the country under discussion. In the Sudanese case, the end of the war and the independence from the British rule marked the slow evolution of an autonomous economic system. However, the lack of experienced personal and the poor investment plans made these attempts fail.

If you are stuck with writing or missing ideas, scroll down and find inspiration in the best samples. Desertification is quite a rare and popular topic for writing an essay, but it certainly is in our database.
Desertification is the process by which fertile land becomes desert, typically as a result of drought, deforestation, or inappropriate agriculture. One major setback that leads to desertification is overgrazing. Desertification Essay Of all the global environmental problems, desertification is, perhaps, the most threatening for poor rural people. The most accepted definition of desertification states that it is land degradation in arid, semiarid, and dry subhumid areas (hereafter called “drylands”) resulting from various factors, including climatic variations and .
