Restoring Our Lands: Combating Desertification, Land Degradation, and Drought

The crisis of desertification, land degradation, and drought is a pressing issue that affects billions of people worldwide. Desertification, which refers to the degradation of land in arid, semi-arid, and dry sub-humid areas, is exacerbated by human activities such as unsustainable land management practices and population growth. Droughts, characterized by prolonged periods of low precipitation, have become more frequent and severe due to climate change.

According to estimates, human-induced land degradation affects at least 1.6 billion hectares globally, directly impacting 3.2 billion people. The expansion of croplands, unsustainable land management practices, and population growth are major drivers of desertification. In turn, desertification exacerbates climate change through changes in vegetation cover and greenhouse gas fluxes.

Droughts pose a significant threat to sustainable development, affecting over 2.3 billion people worldwide. By 2050, droughts may impact over three-quarters of the global population, leading to water scarcity and forced migration. The African continent has been particularly affected by droughts, with projections indicating that up to 216 million people could be displaced by 2050 due to a combination of factors including drought and water scarcity.

Land degradation and restoration play a crucial role in addressing these challenges. Land restoration efforts can sequester atmospheric carbon, support climate change mitigation, and enhance soil productivity. Restoring just 15% of degraded land could prevent up to 60% of expected species extinctions. Additionally, land restoration can bring economic benefits, boost livelihoods, and improve resilience to extreme weather events.

A human rights-based approach to desertification, land degradation, and drought is essential to protect the rights of vulnerable populations, including women, Indigenous Peoples, and local communities. Gender inequalities in land ownership and access exacerbate the impacts of land degradation on women. Indigenous Peoples and local communities often experience a loss of cultural identity and traditional knowledge due to land degradation.

Global responses to desertification, land degradation, and drought include initiatives by the United Nations Convention to Combat Desertification (UNCCD), the UN Environment Assembly, and other international organizations. The UN Decade on Ecosystem Restoration aims to promote the protection and revival of ecosystems worldwide. World Environment Day 2024 will focus on land restoration, desertification, and drought resilience.

In conclusion, addressing the crisis of desertification, land degradation, and drought requires coordinated efforts at the global, regional, and local levels. By implementing sustainable land management practices, restoring degraded land, and adopting a human rights-based approach, we can mitigate the impacts of these environmental challenges and build a more resilient future for all.
