World Day to Combat Desertification and Drought , june 17

The Decay of the Land

Desertification is the degradation of land in arid, semi-arid and dry sub-humid areas. It is caused primarily by human activities and climatic variations. Desertification does not refer to the expansion of existing deserts. It occurs because dryland ecosystems, which cover over one third of the world‘s land area, are extremely vulnerable to overexploitation and inappropriate land use. Poverty, political instability, deforestation, overgrazing and bad irrigation practices can all undermine the productivity of the land.
The World Day to Combat Desertification and Drought is observed every year to promote public awareness of international efforts to combat desertification. The day is a unique moment to remind everyone that land degradation neutrality is achievable through problem-solving, strong community involvement and co-operation at all levels.

Key Issues

• Land & Drought — "By 2025, 1.8 billion people will experience absolute water scarcity, and 2/3 of the world will be living under water-stressed conditions."
  A complex and slowly encroaching natural hazard with significant and pervasive socio-economic and environmental impacts that to cause more deaths and displace more people than any other natural disaster.
• Land & Human Security — "By 2045 some 135 million people may be displaced as a result of desertification."
  Achieving land degradation neutrality -by rehabilitating already degraded land, scaling up sustainable land management and accelerating restoration initiatives- is a pathway to greater resilience and security for all.
• Land & Climate — "Restoring the soils of degraded ecosystems has the potential to store up to 3 billion tons of carbon annually."
  The land use sector represents almost 25% of total global emissions. Its rehabilitation and sustainable management is critical to combating climate change .
