This paper in Current Science deals with the use of biodrainage to combat waterlogging, increase farm productivity and sequester carbon in canal command areas of northwest India. The rise in groundwater table followed by waterlogging and secondary soil salinization is a serious problem in canal-irrigated areas of arid and semi-arid regions. To combat the problem, an agroforestry model for biodrainage was tested in waterlogged fields of Haryana (northwest India), where 10 per cent area (0.44 m ha) is waterlogged resulting in reduced crop yields and abandonment of agricultural lands.
