Desertification, along with climate change and the loss of biodiversity, were identified as the greatest challenges to sustainable development during the Rio Earth Summit in 1992. Two years later, the General Assembly established the United Nations Convention to Combat Desertification (UNCCD), a legally binding international agreement linking environment and development to sustainable land management, and declared 17 June “World Day to Combat Desertification and Drought” (A/RES/49/115).
Desertification, land degradation, and drought are among the most pressing environmental challenges of our time, with up to 40% of all land area worldwide already considered degraded.
Healthy land not only provides us with almost 95% of our food but so much more: it clothes and shelters us, provides jobs and livelihoods, and protects us from the worsening droughts, floods and wildfires.
At the same time, growing populations coupled with unsustainable production and consumption patterns fuel demand for natural resources, putting excessive pressure on land to the point of degradation. Desertification and drought are driving forced migration, putting tens of millions of people each year at risk of displacement.
