Agricultural development has historically focused on poverty reduction and food security but is now increasingly asked to help improve nutrition. Despite this strengthened nutritional mandate, agricultural policies and programs have struggled to develop effective, scalable and cost-effective approaches for reducing undernutrition.

This research was undertaken in order to understand what factors have been driving stunting reduction in Tanzania over the recent past (2005-2015), and what can further accelerate progress against undernutrition in the near future (2015-2025).

Water, sanitation and hygiene (WASH) investments are widely seen as essential for improving health in early childhood.

This brief examines estimates produced by several recent model simulations and frameworks that focus on the cost of ending hunger as well as progress toward other development goals—estimates that range from US$7 billion to US$265 billion per year.
