The agricultural crop system depends on a few major staple crops such as rice, maize, wheat, sorghum, soybeans, amongst others for food production, leaving certain crops underutilized. Even though these underutilized crops have the potentials of diversifying and sustaining the food and nutrition systems while presenting different resilience to climatic conditions. As the world’s population continues to increase and climate change keeps occurring, these major staple crops are being...

Projected changes in temperature and rainfall directly threaten the overall agricultural crop production system in Zambia where 75% of agricultural production is rainfed. This study investigates the effects of future climate on maize (Zea mays L.) and soybean [Glycine max (L.) Merr.] yields using relatively high spatial resolution downscaled climate data in Central and Eastern Zambia. The Agrometshell model was applied to simulate historical and future crop yields. To account for the effects...

Anthropogenic climate change likely influences the beginning of 2020 growing season's water deficit in parts of southern Africa, with severe consequences to food security. The failure of early (October–December) rains, amidst a multiyear drought, has raised concerns of a potential emerging food security crisis in parts of southern Africa, with an estimated 45 million people at risk of severe food insecurity (WFP (World Food Programme), 2019). Here, we evaluate recent climate data to assess...

Abstract Decision makers need accurate information to address climate variability and change and accelerate transformation to sustainability. A stakeholder-driven, science-based multi-model approach has been developed and used by the Agricultural Model Intercomparison and Improvement Project (AgMIP) to generate actionable information for adaptation planning processes. For a range of mid-century climate projections—likely to be hotter, drier, and more variable—contrasting future...

This study provides a unique contribution to improving agricultural systems in the face of changing climate and socio-economic conditions, integratingmulti-modeling research with stakeholder engagement to inform future-oriented decision processes. In areas like semi-aridZimbabwe, rural communities are highly vulnerable to climate variability. Climate risk is not a future issue, but constitutes a current threat to food security, if no improvement actions are taken. This study therefore...

Agriculture in South Africa sustains about 70% of the region’s population for food, income and employment, playing an important role for food security and the local economy. The focus of the study was the commercial maize farms of the Free State Province given their importance in the National economy. The Regional Integrated Assessment (phase I) was implemented to assess climate change and adaptation that links climate, crops, economic data and tools developed by the Agricultural Model...
