Salinity intrusion in soil caused by climate-induced hazards, especially cyclones and sea level rise, is adversely affecting rice production - a key staple food - in coastal Bangladesh. The southwest coastal district of Satkhira is one of the most vulnerable areas because of its high exposure to salinity intrusion and widespread poverty. This paper, published in the International Journal of Global Warming, explores how salinity intrusion affects rice production in the district, and whether existing coping and adaptation measures are sufficient to address the issue. The paper is composed of four sections: a very brief overview of the major climate change events affecting coastal Bangladesh, the concept of loss and damage, and a short description of the case study area; a description of the tools and techniques used to collect field data, including a survey of 360 farming households in four villages, focus group discussions, in-depth interviews, and community consultations; discussion on the salinity levels in the soil and its associated impacts, current adaptation practices, an estimation of loss and damage in the study villages, and potential adaptation measures; and finally concluding remarks. This research demonstrates that salinity levels in the soil have increased sharply over the last 20 years, with respondents claiming rapidly increasing salinity within the last five years in particular. Meanwhile, the proportion of salinity-free farmland has gone down over the past two decades, from more than 60% to nil, severely impacting agricultural productivity. This has resulted in food crisis in the villages; a majority (63%) of the study households were found to be facing a food crisis at some time of the year. The introduction of saline-tolerant rice cultivars has been the most important adaptation measure being practised, while other adaptation measures include washing rice fields periodically to reduce salinity, and non-farming measures such as financial loans and migrating to find alternative incomes. However, these adaptation measures have not been enough to deal with the sudden increase in salinity after cyclone Aila in 2009, a year in which the study areas lost their entire potential yield of aman rice production. The paper concludes that a future cyclone with a higher level of storm surge could cause saline intrusion further into the landmass, thus threatening the whole coastal region and its 33 million people (though disproportionately impacting the very poorest). Low-lying agricultural land needs to be securely protected, and innovative and context specific practices, including climate-resilient rice cultivation, must be researched and implemented.
