A 3-year research-for-development initiative in the Barotse floodplain, Zambia, supported by the CGIAR research programs Aquatic Agricultural Systems and Agriculture for Nutrition and Health, brought scientists and community members together to improve food and nutrition security all year round.

In recent years, export bans on staple crops have become more and more common as countries attempt to safeguard their domestic food supplies and protect their populations from international food price spikes. Research has shown, however, that such policies often do more harm than good, reducing the prices that local producers receive for their goods and increasing uncertainty in the market for both farmers and traders.

As drought continues throughout southern Africa, the latest FEWS.net alert estimates that 2.5 million people are currently in Crisis food insecurity levels and in need of urgent humanitarian aid across Malawi, Zimbabwe, Mozambique, Madagascar, and Lesotho. The organization is also anticipating that the region’s food-insecure population in 2016-2017 will be at least two times higher than current levels.

The surge in digital technologies available over the past few decades has transformed virtually every sector of the global economy, and agriculture is no exception. Information and communications technologies (ICTs) such as mobile phones and SMS messaging are changing the way farmers track weather patterns, access market information, interact with traders and government agencies, and get paid for their crops.

The impacts of climate change on agriculture can differ widely depending on a variety of factors, including the region of production, crop variety, and availability and use of inputs like fertilizers and irrigation. Gender can also play a large role in how individuals both experience and respond to climate change. Since gender norms often at least partially establish individuals’ social status, rights, and responsibilities, it is likely that men and women face different constraints and opportunities and will make different decisions when it comes to adapting to climate change.
