2016 AGROFORESTRY FOR THE MANAGEMENT OF WATERLOGGED SALINE SOILS AND POOR-QUALITY WATERS 2016 13(卷), null(期), (109-120页)
Indira Gandhi Nahar Pariyojana/Project (IGNP) in the Thar Desert is one of the largest irrigation projects in the world. As a result of this initiative, 1.86 million hectare area has come under cultivation. Although irrigation has greatly increased the agricultural production potential, it has also rendered vast tracts of land under waterlogged category (leading to salinization as well) on account of seepage and deep percolation losses from the irrigation network and lack of a proper drainage system. The concept of biodrainage, removal of groundwater through evapotranspiration, has emerged as an effective way to tackle this problem. Such an approach is economical and eco-friendly. However, more research is required to fully understand the implications, especially at farm level. The policy to control the problems associated with waterlogging and salinization should include biodrainage, reduced water allowance, efficient irrigation, and conjunctive uses.
