Breeding and seed systems must be adapted to survive projected climate change if major loss of maize yields is to be avoided, a new report shows.

Tools that forecast the response of crops to different weather and climate conditions, coupled with crop yield modeling have enabled agricultural scientists to predict and formulate plans for potential future climate change.

Maize seed systems in Africa: Understanding the basics

Maize is not only a staple in diets across sub-Saharan Africa (SSA) – it is a cash crop that supports millions of farmer households. Maize is grown on over 33 million hectares in just 13 of 48 SSA countries – accounting for 72% of all maize produced in the region. This crop, without a doubt, is king.

However, rising temperatures and erratic rainfall patterns threaten maize production across the continent. Total crop loss occurs if there’s little or no rainfall at the flowering stage, when maize is most vulnerable. And when temperatures increase, soil moisture is quickly depleted and farmers have to resort to prolonged irrigation, a costly undertaking for smallholders.

Drought-tolerant (DT) maize varieties produce better yields both in good and bad seasons compared to most commercial varieties available in the region. Since 2006, CIMMYT has developed 200 drought-tolerant varieties and hybrids, many of which also possess desirable traits such as resistance to major diseases.

IWD 2016: Super women of Africa

For International Women’s Day 2016, CIMMYT and MAIZE celebrate women farmers in Africa, who through their resilience, bravery and commitment have weathered challenges in maize farming to put food on the table. These women contribute to enhancing agricultural growth and food security.

Participatory approaches to gender in agricultural development.

When designing and implementing agricultural development projects, it is difficult to ensure that they are responsive to gender dynamics. For Mulunesh Tsegaye, a gender specialist attached to two projects working on the areas of nutrition and mechanization in Ethiopia, participatory approaches are the best way forward.

“I have lived and worked with communities. If you want to help a community, they know best how to do things for themselves. There are also issues of sustainability when you are not there forever. You need to make communities own what has been done in an effective participatory approach,” she said.
