In Bangladesh, pressures from population growth, acute food shortages and poverty mean that around 60% of the population suffers from undernutrition. The Expansion of Cereal Systems Initiative for South Asia (CSISA)  project brings together local partners, the International Rice Research Institute, the International Maize and Wheat Improvement Center and WorldFish to fight food insecurity through the creation of six regional hubs that promote technology innovation and improve agricultural and aquaculture productivity. The project aims to promote food and nutrition security through greater crop diversification. WorldFish focuses on the development small-scale pond aquaculture (fish farming) and gher agriculture.
