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.
Measurement of riverine biota, particularly benthic macroinvertebrates (such as crustaceans and aquatic insects) and fish, has become a widely accepted method of identifying the structural or functional integrity and the overall health of a riverine system. This manual from the Kerala State Biodiversity Board (KSBB), describes in detail the field procedures to be followed in such fish monitoring/measurement surveys, conducted for riverine ecological systems.
KSBB has taken up this manual publication effort, in the conxtet of a state-wide fish monitoring programme, that aims to survey all the 44 rivers of Kerala with the involvement of resource persons from local colleges, research institutes, experts and fisherpeople community.Read More
Climate change will affect everyone but developing countries will be hit hardest, soonest and have the least capacity to respond. South East Asia is particularly vulnerable to the impacts of climate change with its extensive, heavily populated coastlines, large agricultural sectors and large sections of the population living under $2 or even $1 a day.
