With a population over 156 million people, 80 percent of whom live in rural areas, an average density of 940 persons per km2 (the 9th most densely populated country in the world) and 70 percent of land area five meters or less above sea level, environmental hazards such as floods, cyclones, salt water intrusion and river erosion are expected to have massive destructive impacts in Bangladesh. In effect it is estimated that 30 to 50 percent of the country is affected by severe climatic shocks every year (WFP 2012a). These events have killed hundreds of people and injured thousands, ruined thousands of hectares of crops and washed away large areas of cultivable land, homes, and productive assets, amounting to huge human and economic losses. In Bangladesh, undernutrition has long been recognized as a problem of significant magnitude, with 24% of women underweight and 13% of short stature, 41% of children under five years of age stunted in 2011, and 36% underweight (BDHS 2011). Undernutrition rates in Bangladesh are already among the highest in the world (NDRI 2010). In this context, a legitimate question is whether these described extreme events that are continuously affecting Bangladesh contribute significantly to the situation of undernutrition. One hypothesis is that the impact of climate related shocks and stresses on food security and nutrition in Bangladesh could be particularly severe given the reliance of a majority of poor rural households on agricultural livelihoods.
