Desertification and agriculture

Briefing 10-02-2020

Desertification is a land degradation process that occurs in drylands. It affects the land's capacity to supply ecosystem services, such as producing food or hosting biodiversity, to mention the most well known ones. Its drivers are related to both human activity and the climate, and depend on the specific context. More than 1 billion people in some 100 countries face some level of risk related to the effects of desertification. Climate change can further increase the risk of desertification for ...

Das Ziel dieser Studie besteht darin, die derzeitige Lage in Bezug auf die europäischen Süßwasserressourcen zu veranschaulichen und zukünftige Herausforderungen aufzuzeigen. Zunächst wird die aktuelle Wasserverfügbarkeit und -qualität mit den Aspekten Klimawandel, Energie, Finanzierung und Naturschutz verknüpft. Im Anschluss daran werden derzeitige Probleme und Herausforderungen in Bezug auf Wassereffizienz, Landnutzung, wirtschaftspolitische Instrumente, Kenntnisstand, staatliches Handeln, globale ...

China is facing a plethora of environmental challenges, most a result of rapid economic development, which is linked to heavy industrialisation. These challenges include air pollution, contamination and scarcity of water, desertification, and acid rain. The public lacks information on environmental hazards or contentious projects. Recognising many of these problems, Beijing has taken various measures since the mid-2000s, for instance on energy efficiency, renewable energy, pollution and water scarcity ...

Executive summary This report sets out to provide an integrated picture of land degradation issues and actions within the EU. Findings from literature, academic research and policy analysis are brought together within this study, in order to explain: the extent of degradation to date in Europe and globally; the drivers and pressures leading to this; the impacts of degradation both directly upon the land and indirectly in relation to inter alia water resources, climate change, food production, biodiversity ...

Climate plays a major role in determining the yield levels, the year-to-year variability and the spatial patterns of global agriculture. Agriculture is sensitive to short term changes in weather and to seasonal, annual and longer term variations in climate. Over the long term, agriculture is able to tolerate moderate variations about the climatic mean. Longterm marked changes in temperature, precipitation, and solar radiation will have an effect on the productivity of crop and livestock agriculture ...
