Introducing winter rice cropping by using non-saline tidal water influx in western basins of South 24 Parganas, India

Abstract A population exceeding 3.8 million people in the western region of 24-Parganas (South) is directly or indirectly reliant on agriculture as their primary source of livelihood. The agricultural trend shows a clear lack of multi-cropping with a drop of nearly 30% in rice cultivation during the...
