As the financial mechanism of the Global Environment Facility, the Global Environment Facility has the responsibility to deal with land degradation, paying special attention to desertification and deforestation. The Global Environment Facility (GEF) defines land degradation as "any form of deterioration of the natural potential of land, which will affect the integrity of the ecosystem, manifested by reducing its sustainable ecological productivity or reducing its original biological richness and toughness."

Land degradation is the main threat to biodiversity, ecosystem stability and social function. Because cross-scale ecosystems are interrelated, the destructive process caused by land degradation can have a cascade effect in the whole biosphere. The depletion of vegetation has caused the loss of biomass. With the intensification of soil erosion, greenhouse gases have been produced, which has aggravated global warming and climate change.

Therefore, the impact of land degradation goes far beyond the local or regional scope. It is very important to invest in land management in order to maintain a large number of global environmental benefits obtained by human beings from the ecosystem.

Promote the realization of the objectives of the United Nations Convention to Combat Desertification.

In 2003, the Global Environment Facility (GEF) was designated as the financial mechanism of the United Nations Convention to Combat Desertification to ensure that GEF projects to combat desertification meet the objectives of the Convention. In this way, the Global Environment Facility (GEF) has played the role of a supplementary financial mechanism for this global mechanism and supported the implementation of the Convention.

The identification of key land degradation areas and the official designation of the Global Environment Facility as the financial mechanism of the United Nations Convention to Combat Desertification have greatly promoted the investment of the Global Environment Facility in sustainable land management projects.

As the financial mechanism of the United Nations Convention to Combat Desertification, the Global Environment Facility (GEF) has made a direct contribution to the realization of the ten-year strategic plan and framework (2008-2065-438+08) adopted by the eighth meeting of the Conference of the Parties. The strategic plan aims to "establish a global partnership to support poverty reduction and environmental sustainability, so as to reverse and prevent desertification/land degradation and alleviate drought in the affected areas".
