Nutrition

The ramifications of climate change on human health are vast: agriculture, nutrition, diets, and health as a whole are negatively affected. Climate is both a potential driver and outcome of changes in nutritional status. In addition to direct and indirect impacts on health as a whole, climate change influences nutritional status through the enabling, food, work and social, health, and living environments, which ultimately leads to disrupted health behaviors and biological status, disease, diminished productivity, and mortality. The intersection of climate change, food security and nutrition is critical given growing adverse climate change impacts that threaten the food security and nutrition outcomes of the most vulnerable in the Global South the most. A better understanding of the pathways linking climate change with nutrition is critical to develop effective interventions to ensure that the world’s population has access to sufficient, safe, and nutritious food.

Using natural areas and empowering women to buffer food security and nutrition from climate shocks: Evidence from Ghana, Zambia, and Bangladesh

As climate change makes precipitation shocks more common, policymakers are becoming increasingly interested in protecting food systems and nutrition outcomes from the damaging effects of droughts and floods (Wheeler and von Braun, 2013). Increasing the resilience of nutrition and food security outcomes is especially critical throughout agrarian parts of the developing world, where human subsistence and well-being are directly affected by local rainfall. In this study, we use data from Feed the Future datasets from Ghana, Zambia, and Bangladesh to examine the impact of precipitation extremes on food security as well as the role of natural land cover and women’s empowerment in creating resilience. We first model the effects of extreme rainfall on indicators of nutrition and food security, and then examine whether women’s empowerment and environmental land cover types can dampen the effects of rainfall shocks on these food security and nutrition outcomes. Our results find that there is a strong association between extreme precipitation and household hunger. Further, they suggest that in certain contexts land cover types providing ecosystem services can reduce household hunger scores, that empowering women can mitigate the effects of precipitation shocks, and that there may be an interactive effect between ecosystem service availability and women’s empowerment.

Call for Promising Practices to Advance Gender Equality, Nutrition Security, and Climate Resilience

Across sub-sectors of rural climate resilience – including social protection, disaster risk reduction, livelihood diversification, climate-smart agriculture, among others – what are promising approaches to address gender and nutrition in project design and evaluation?

Climate Change and Nutrition Linkages - Discussion Paper, Policy Note, Slide Deck

The intersection of climate change, food security, and nutrition is critical given growing adverse climate change impacts that threaten food security and nutrition outcomes, especially for the most vulnerable in the global South. The GCAN team put together a discussion paper which uses a food systems approach to analyze the bidirectional relationships between climate change and food and nutrition along the entire food value chain.
