  Desertification is a serious form of land degradation that results in the destruction of natural ecosystems and the end of services they provide for us. This includes natural filtration of water for drinking, climate regulation, recycling of nutrients, carbon sequestration, soil regeneration. Global environmental change. Large-scale and global environmental hazards to human health include climate change, stratospheric ozone depletion, changes in ecosystems due to loss of biodiversity, changes in hydrological systems and the supplies of freshwater, land degradation, urbanization, and stresses on food-producing systems.

The End of Desertification. Disputing Environmental Change in the Drylands.

This book takes issue. Biological and Environmental Hazards, Risks, and Disasters provides an integrated look at major impacts to the Earth’s biosphere. Many of these are caused by diseases, algal blooms, insects, animals, species extinction, deforestation, land degradation, and comet and asteroid strikes that have important implications for humans.

  Arid ecosystems cover about 40% of Earth's land area and are home to over two billion people, yet they remain vulnerable to climate change and Cited by:   An exhaustive guide to the management, suppression, and ecological significance of forest fires. Debut author Gboloo begins the first installment in his four volume series by outlining the destructiveness of global warming as attested by the most recent scientific findings.

It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. This book is an effort to critically examine that experience and accelerate the learning process in other parts of the world. Read moreRead less.

Environmental Issues - Desertification. As science over many decades has shown, and this book emphasizes again, non-equilibrium ecology is a useful way of thinking about complex, highly variable dryland ecosystems - especially in the context of climate change (Scoones ).

In particular, it provides a useful basis for challenging simplistic, linear desertification : Ian Scoones. rows  Desertification - the spread of desert-like conditions in arid or semi-arid areas, due to. Desertification is the process of ecological degradation by which economically productive land becomes less productive, in some cases leading to the development of a desert-like landscape.

There is a huge literature on the nature and causes of desertification, some of which indicates that human impacts arising from overstocking, overcultivation, and deforestation are primarily responsible for the process; some lays the blame on the impact of extended droughts.

Activities resulting in global climate change are expected to trigger droughts with a substantial impact on agriculture throughout the world, and especially in developing nations Figure 5 is a detailed mind map as to how desertification occurs.

This book will change. Disputing environmental change in the drylands is a landmark book about the concept of desertification, featuring contributions from a global team of experts on dryland issues.

The second chapter, entitled 'Desertification in the Sahel: local practice meets global narrative', is written by Toulmin and Karen Brock. ECOLOGICAL CHANGE AND DESERTIFICATION Desertification, defined as a persistent decline in the production of dry ecosys- tems, may be a pragmatic concept, but it is hard to pin down.

For, if there is little evidence to suggest a secular change in climate as the causal mechan- ism in desertification Cited by: Desertification has occurred worldwide.

The biophysical and socio-economic complexity of this phenomenon has challenged our ability to categorize, inventory, monitor and repair the condition of degraded lands. One of the most important distinctions to be made in relation to land degradation is between cultivated land used for annual crop production and `rangelands'.Reviews: 1.

Climate change: Climate change manifests in the form of failure of monsoons, irregular monsoons and frequent droughts thereby leading to desertification Pollution: Excessive use of fertilizers and pesticides to increase yield and disposal of toxic wastes into land leads to : Mrinal Gour.

This book identifies key vulnerabilities to the combined effects of climate change and land degradation around the world. It identifies triple-win adaptations that can tackle both climate change and land degradation, whilst supporting biodiversity and ecosystem services.

Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly more arid.

It is the spread of arid areas caused by a variety of factors, such as through climate change (particularly the current global warming) and through the overexploitation of soil through. While interpretations of the term desertification vary, the concern centers on human-caused land degradation in areas with low or variable rainfall known as drylands: arid, semi-arid, and sub.

Desertification, the process by which natural or human causes reduce the biological productivity of drylands. Such declines may be the result of climate change, deforestation, overgrazing, poverty, political instability, unsustainable irrigation practices, or combinations of these factors.
