Présentation

Given the current demographic trends and global warming, as much as 60% of the global population may suffer serious water scarcity by the year 2025. Agriculture is likely to suffer the most unless more efficient water management is practiced, particularly in drylands. Mulching is an efficient method controlling evaporation. Reducing evaporation loss helps to conserve soil moisture and control salt accumulation. Since saline water resources are more abundant than fresh water, the careful use of saline or diluted seawater is important for agriculture. Irrigation scheduling also plays an important role in developing water-saving agriculture. Determination of threshold value at which irrigation should be scheduled is necessary for water-use-efficient production. This study was carried out from 2005 to 2008 at the Arid Land Research Center, to evaluate mulching effect for sustainable agriculture and establish irrigation threshold for water-saving production.
