Waterlogging and secondary salinisation have become serious problems in canal irrigated areas of arid and semi-arid regions. This study examined hydrology and estimated the seasonal net groundwater recharge of an irrigated semi-arid region located in the Haryana State of India where about 500 000 ha area are waterlogged and unproductive, and the size of the waterlogged area is increasing, causing a threat to agricultural sustainability.

This new study of nine coastal cities around the world published in the latest edition of journal Natural Hazards, says that Kolkata is among the most flood vulnerable cities in world and could experience coastal flooding as the city is built on river delta.

Despite being dotted with industries, Gujarat's rich coastline is plagued by voices of dissent. Coastal communities have of late realised that the fruits of industrialisation were either too sour, or not for them at all.

The growth and plant water relations of Eucalyptus tereticornis Sm. and E. camaldulensis Dehnh. in relation to soil salinity were studied by transplanting one and half month old seedlings in the pots filled with eight levels of artificially created soil salinity levels.
