DESERTIFICATION

What is desertification? Desertification is the persistent degradation of dryland ecosystems by climatic variations and human activities. Approximately, 41% of the world’s landscape is covered by drylands. The drylands are home to about 2 billion people on earth. Desertification threatens these drylands that we call home. It is thought that some 10% to 20% of drylands, or some six to twelve million square kilometres may already have been degraded. Most drylands are in developing countries in which the people are behind in reference to well-being and human development. The mortality rate are very high in these lands, typically around 54 per 1000 in some areas. Expanding populations have brought the need to produce more food. About 5 million km that were once grassland are now converted to crop land. Globally more than 2 million km of this rain-fed cropland has been moderately or severely degraded and each year about one per cent is abandoned to become desert. Furthermore, the irrigation projects used in these areas has caused inland waters to become infested with salt (salinity) and caused a huge decline in biodiversity. This only leads to more land loss. In the years to come desertification is expected to increase. The driven factors for the increase in desertification are poverty and the unsustainable use of land. Climate change is also a factor in desertification but the impact depends upon the area and region.
To change the drastic effects of desertification, nations would have to improve agricultural and grazing practices in a sustainable way. The concept of creating a “cultural of prevention” must be implemented by both government and humans alike.
Possible actions include: * Integrating land and water management * Protecting vegetative cover * Integrating the use of land for grazing and agricultural purposes * Combining traditional practices with land use technologies * Giving local communities the capacity to manage their resources effectively * Developing alternative livelihoods that don't depend on traditional land use * Creating economic opportunities in dryland urban areas.

Environmental Reporting

...CHAPTER ONE INTRODUCTION 1.1 Background to the Study The need for Environmental Accounting has become the concern and focus of nations and responsible corporate managements. It became one of the foremost issues on the agenda of nations and businesses earlier in the 1990s and the reasons for this were varied emanating from both within and outside of the firm and particularly at the global level (Okoye and Ngwakwe:2004:220-235). A lot of government enactments, laws and regulations on environmental protection have been made in several nations of the world. In the light of the awakening to environment protection, various laws and regulations such as the Environmental Impact Assessment Act, 1992 have been enacted. These require corporate managements to consider the environmental implications of all internal decisions of their managements. Also, all organizations monitored by environmental policy agencies in Kenya are expected to demonstrate much consideration in decision making. Environmentalists agree that it could be more cost effective and beneficial for companies to acquire pollution prevention or clean technology than those of pollution clean-up. It is also observed that in environmental regulations, there is a shift from the ‘command and control’ approach to market-driven forms in which pollution prevention alternatives are replacing pollution cleaning approach. It follows therefore, that determining the appropriate pollution prevention approach may lead to additional decisions...

Environmental Awareness

...the world, environmental education has been included as a part of the curriculum in schools and colleges. This project attempts to study whether and to what extent has the formal method of imparting environment education in schools has been effective by studying the status of environmental awareness of school children. Many new townships and cities have sprung up during the last fifty years. Urbanization has had its impact on the previously uninhabited areas and the natural resources therein. The neglect of the masses has resulted in environmental degradation. To reverse this trend there is a need to convince the people about the importance of nature conservation and adoption of eco-friendly practices. The first step towards this is the creation of environmental awareness among the people. However, this should begin at the school level when the children’s minds are impressionable. ‘CATCHING THEM YOUNG’, is the most effective way of creating environment awareness and thus preparing the children to become ‘eco-soldiers’ in their later lives. Though environmental education is currently imparted by giving information on related topics through subjects like science, geography, civics and community living; there is a need to ascertain the effectiveness of this formal method by studying the level of environmental awareness. Realizing the importance of this fact, an attempt is made through this study to determine the level of environmental awareness...

Environmental Law

...Everywhere in the world, the issue of climate change presents an archetypal environmental problem. Communities often fight governments, both at the state and national levels in a bid to protect the environment they have known for ages. Governments, on the other hand, protect these natural settings by formulating laws and policies that ensure the society does not lose its treasures[1]. However, some seek to use the protected spaces as a means of developing projects that will provide the state or nation with more resources, revenues and products. These may be good developmental projects, but they ought to protect the environment first before they can sell such ideas to a conservative society. As in all other nations, Australia has also been engulfed in a fight to save the environment as the government looks at creating developmental projects that will necessary block any advantages that the local community has enjoyed since time immemorial[2]. By seeking to repeal at least 60% of protection that the New South Wales Far North Coast’s forests, wetlands and wildlife habitant, the government is slowly seeking to destroy the local community. Conservatives will agree that the best way of protecting the environment is by setting aside a portion of some indigenous scenery and protect it from encroachment[3]. However, encroachment is still a biting problem and the recent statements by the authorities only heighten the environmental issues at hand. Legal processes and issues have arisen with groups...

Environmental Issues

...Environmental Issues Carissa Gilson Soc 120 introduction to Ethics & Social Responsibility Ms. Soard 8/12/2010 History of environmental ethics: It started in the late 60’s with the publications of Lynn White’s “The Historical Roots of our Ecologic Crisis” (March1967) and Garret Hardin’s “The Tragedy of the Commons” (December 1968). These publications and others started the debate into environmental issues. The first thing they needed to do was to decide what” the field of environmental ethics might look like”. There were many philosophers who got into the mix and started writing publications as well. Then in the 1990’s the International Society for Environmental Ethics was founded through the efforts of Laura Westra and Holmes Rolston, III (www.cep.unt.edu/novice). This started today’s various organizations such as Greenpeace, the earth charter initiative, the environmental protection society, friends of the earth to mention just a few. These organizations are designed to create an awareness of today’s environmental issues. Some of the issues we are facing in the future seem to have to do with global warming and its impact on the earth’s environment. The issue here seems to be our use of gas and oil and the need for an alternate energy source. There are so many thoughts as to what should be done in this area; it makes your head spin. I’m all for green technology provided it really works. It is very hard to sort out what green really means to the average person. One...
