The United Nations Convention to Combat Desertification in Those Countries Experiencing Serious Drought and/or Desertification, Particularly in Africa (UNCCD) is a Convention to combat desertification and mitigate the effects of drought through national action programs that incorporate long-term strategies supported by international cooperation and partnership arrangements.

Displaying 311 - 315 of 586PowerPoint Presentation: Land Degradation Neutrality (LDN)
Over the last three decades the issues of sustainability have been addressed and policy options have been proposed at the global, regional and sometimes at the national level to revert the negative trends on the social, economic and environmental aspects of development. But still, we are in front of a scenario that indicates that if land resources are not managed in a sustainable manner, the inter-generational issue of sustainable development will not be achieved.
Climate change and desertification: Anticipating, assessing and adapting to future change in drylands
Drylands have always been the subject to intra- and inter-annul fluctuations of climate conditions, with important consequences for ecosystem function and productivity.
Land Matters for Climate Reducing the Gap and Approaching the Target
The land use sector represents almost 25% of total global emissions. These emissions can be reduced. There is also great potential for carbon sequestration through the scaling up, and scaling out, of proven and effective practices. Improved land use and management, such as low-emissions agriculture, agro-forestry and ecosystem conservation and restoration could, under certain circumstances, further reduce the remaining emissions gap by up to 25%. These climate-smart land management practices nearly always come with adaptation co-benefits.

Land degradation and desertification reduce the provision of ecosystem services by lands and soils. This constrains development, reduces water, food, and energy security, and triggers resource conflicts. Although biophysical processes and economic impacts are increasingly understood, efforts to combat degradation have been failing thus far to prevent further losses of land productivity, a cost estimated at 42 billion USD/year (Dregne & Chou, 1992; Requier-Desjardins, 2007).
Land and Bioenergy (Chapter 9 from "Bioenergy and sustainability: Bridging the gaps")
Projected land demands for bioenergy fall well within conservative estimates of current and future land availability (240 to 905 Mha). Estimates for the amount of modern bioenergy needed to meaningfully mitigate climate change range from 80 to 200 EJ in the 2050 timeframe. At the upper end of this range, we estimate that about 200 million hectares would be required. This may be compared to most estimates for the amount of land available for bioenergy, which exceed 500 million hectares.
