No results found.Drainage of agricultural land is one of the most critical water management tools for the sustainability of productive cropping systems, as frequently this sustainability is extremely dependent on the control of waterlogging and soil salinization in the rootzone of most crops. On some agricultural lands, the natural drainage is sufficient to maintain high productivity. However, many others require improvements in surface and subsurface drainage in order to optimize land productivity, wh ile maintaining the quality of soil resources. As time passes, drainage requirements may change because of changes in the general socio-economic conditions, such as input and output prices, and more intensive crop rotations. -

Clearly it has an emphasis on agricultural water use and management. But in addition it contains the relevant tables and maps, and a regional synopsis emphasizing the particular characteristics of this large and diverse region. It also analyses the changes that have occurred since the first survey in 1999. Finally it gives a more detail ed description of four transboundary river basins in the region, highlighting the different levels of cooperation and the agreements between countries located in the same river basin: the Ganges?Brahmaputra?Meghna basin, the Indus basin, the Mekong basin and the Salween basin.
