This document presents a value chain study with an integrated gender lens of the aquaculture sector in Rajshahi and Rangpur in northwestern Bangladesh. The study forms part of the contextual knowledge foundation for the IDEA project, which works in all 16 districts of Rangpur and Rajshahi divisions. Its ultimate goal is to reach 1 million households for its aquaculture production outcomes and 2 million households for the nutrition outcomes. The aim of the value chain study was to generate a knowledge base for designing project interventions. These focus specifically on inclusive aquaculture value chains that are both more productive and contribute to poverty reduction, and in which women and youths can be equitably included and benefit in safe and dignified manners.
