Why do we need immediate actions in drylands? Climate change, food insecurity, and biodiversity loss are becoming increasingly important drivers of land degradation.The process of land degradation is particularly acute in the drylands, which are home to more than 2 billion people and contain 44 percent of the world's agriculturally productive land.
15 de may. de 2023 · Drylands. Drylands, characterized by water scarcity, comprise 83% of DOI-managed lands. Drylands are highly vulnerable to erosion by wind and water and are affected by land use (e.g., grazing) and disturbance (e.g., fire). The Climate R&D Program conducts research to understand the primary climatic and non-climatic drivers of change in dryland ...
Drylands play a vital role in local, but also global climate regulation. Land use change releases greenhouse gases into the atmosphere, while soil improvement is essentially the reverse process.
19 de jul. de 2017 · Over drylands, the air is almost always “thirsty” for water, but precipitation is not enough to meet this demand. A term associated with drylands is aridity, which implies a permanent water deficiency closely related to strong insolation, high temperature, strong PET, and low humidity [Mainguet, 1999].
Cropping systems are designed and managed to achieve human goals so they are purposeful systems. 2. Like all purposeful systems, a cropping system has generic properties that are useful to assess how it functions and how effective it is. The most relevant properties here are sustainability and productivity (efficiency).

8 de sept. de 2012 · Although drylands were implicitly recognised, there continues to be inadequate attention to this major biome that covers such a vast part of our world’s terrestrial surface. Yet, as this book conveys, conservation and sustainable management of drylands biodiversity offers a viable pathway to deliver international conservation and development targets.
