Drylands and land degradation

Drylands are found in tropical and temperate latitudes and account for 41.3% of the global terrestrial area. Drylands can be classified into four types - dry sub-humid, semi-arid, arid and hyper-arid lands - and encompass a variety of ecosystems.聽

About drylands and land degradation

Drylands share one or several of the below characteristics:

  • scarcity of water, but not necessarily low rainfall.
  • not all suffer from water shortage, but all face high levels of potential water loss
  • the potential loss of water through evaporation and transpiration is significantly greater than the mean precipitation
  • high evapotranspiration rates and high uncertainty of precipitation.
  • Precipitation in drylands can be high

Drylands are tropical temperate regions that have an Aridity index of less than 0.65 Aridity Index

香港六合彩开奖结果现场直播 Definition, 2008

The real determinant of aridity is evapotranspiration, which is influenced by temperature, wind and vegetation among other factors.

Specifically, this Initiative聽has three strategic priorities:

  • Generate聽evidence聽for targeting and monitoring聽of dryland conditions and trends through adapted assessment approaches that operationalize current understanding on non-equilibrium dryland ecology.

  • Strengthen聽governance for sustainable land management聽by strengthening of resource rights, establishment of institutional mechanisms for ecosystem management, and development of enabling conditions for policy implementation and revision.

  • Promote policy implementation for dryland ecosystem management聽by enhancing the knowledge and capacity聽of various聽stakeholders to adapt policies and investments to the unique conditions of the drylands.

Further, as the 香港六合彩开奖结果现场直播 Focal Point to the United Nations Convention to Combat Desertification, the Global Drylands Initiative leads 香港六合彩开奖结果现场直播's efforts to influence the global discourse on Land Degradation and Sustainable Land Management. In this case, the Initiative supports聽countries to implement their commitments聽to the Convention by demonstrating good practices on the ground, influencing the science-policy interaction of the Convention itself and working with other stakeholders to achieve聽Land Degradation Neutrality.
