In early 2012, the Strengthening Partnerships, Results, and Innovations in Nutrition Globally (SPRING) project began to develop a model for improving nutrition and food security that could be quickly scaled up across its Feed the Future zone of influence along the coastal belt of Bangladesh. This guide is meant to accompany and supplement the broader collection of materials produced for the program and provides practical information on the evidence and foundations of the farmer nutrition schools approach and SPRING’s experience implementing it in Bangladesh. It also explains how to adapt the approach to other countries and settings and suggests monitoring and sustainability tools that can make the program more successful.
