The Climate of coastal lowlands of Andaman Islands is not conducive for agriculture due to various environmental factors. Fewer rainy days, increasing length of dry spell along with soil salinity during the dry season makes agriculture highly vulnerable in this area. It is vital to manage the threat emanating from the rising mean global temperature and sea level to ensure the sustainable livelihood of people inhabiting these areas. In addition, after the 2004 tsunami, seawater is gushing into the land more often, inundating paddy fields.
Realizing that agriculture and livelihood are being severely affected by saline water intrusion and climate change, the ICAR-Central Island Agricultural Research Institute, Port Blair, under the National Agricultural Innovation Project, demonstrated a raised bed and furrow system in the field of Mr. Ranjit Baroi and ten other farmers at Collinpur Village, South Andaman Island. Since then, life has dramatically changed for Mr. Baroi in a span of three years from 2012.
