Climate variability has a profound influence on fisheries and aquaculture in Bangladesh, including service industry and value chains. Progress in weather and sub-seasonal or seasonal forecasting has significantly increased the information available to reduce the exposure to extreme climatic events and also to manage day to day operations of fish farmers for reducing climate variability (like high temperatures, cold spell, heavy rain and dry spell) induced risks. Timely, reliable and contextualized climate information will profoundly change the climate risk equation in the aquaculture sector that underpin food security of millions. However, climate services research and projects addressing food security in Bangladesh have largely focused on land-based agriculture. Information about the specific needs for climate services in the aquaculture sector remains scarce. Consequently, World Fish jointly with CIMMYT and ICRISAT; and IRI (Columbia University) as a CAFFSA unfunded partner; and with kind support from BMD, have been working on identifying climate sensitive aquaculture management decisions and on developing a decision support tool to enhance climate services for aquaculture in Bangladesh under the Climate Change Agriculture and Food Security (CCAFS) programme funded project entitled “Capacitating Farmers and Fishers to manage climate risks in South Asia (CaFFSA)”. While climate services for agriculture have been explored and developed around the world, there has been very little focus so far on fisheries and aquaculture. This session video discusses the very new and emerging field of climate services for aquaculture. It will highlight how climate impacts are affecting the aquaculture sector, leading to fish loss that are detrimental to nutrition and food security, and will present the state of the research on climate products to support this sector.
