Desertification is the process of land degradation in arid, semi-arid, and dry sub-humid regions, resulting in reduced biological productivity and loss of ecosystem services.

Desertification is caused by a combination of factors, including climate change, overgrazing, deforestation, and unsustainable agricultural practices.

Desertification can lead to poverty by reducing agricultural productivity and livelihoods, while poverty can lead to desertification through unsustainable land use practices.

Goal 7 of the MDGs aims to ensure environmental sustainability, including combating desertification and land degradation.

Desertification can reduce agricultural productivity, increase food prices, and lead to malnutrition and hunger.

Sustainable land management practices can help to improve soil fertility, reduce erosion, promote biodiversity, and enhance ecosystem services, all of which contribute to combating desertification.

The United Nations Convention to Combat Desertification (UNCCD) is the sole legally binding international agreement linking environment and development to sustainable land management.

The ultimate objective of the UNCCD is to achieve a land-degradation neutral world, where the amount of land restored is at least equal to the amount of land degraded.

Local communities play a crucial role in combating desertification by implementing sustainable land management practices, raising awareness, and holding governments accountable for their commitments.

Technology can play a significant role in combating desertification by providing data and information for monitoring and assessment, early warning systems, and support for sustainable land management practices.

International cooperation is essential for combating desertification by facilitating knowledge sharing, mobilizing financial resources, and promoting policy coherence and coordination.

Achieving the UNCCD's target of a land-degradation neutral world faces challenges such as climate change, poverty, inequality, and lack of political will and commitment.

There are several success stories in combating desertification, including the Great Green Wall in Africa, the Loess Plateau Restoration Project in China, and the Sahel Initiative.

Individuals can help combat desertification by reducing their carbon footprint, supporting sustainable agriculture and land management practices, and educating themselves and others about desertification.

Desertification can be reversed if we implement sustainable land management practices, restore degraded land, and address the underlying causes of land degradation.
