Reduced tillage, permanent ground cover and crop diversification are the three core pillars of Conservation Agriculture (CA).We assess and compare on-farm effects of different practices related to the three pillars ofCA on maize yields under ENSO-driven rainfall variability in Kenya and Malawi. R...

Can smallholder farmers buffer rainfall variability through conservation agriculture? On-farm practices and maize yields in Kenya and Malawi
Efforts to increase agricultural productivity, adapt to climate change, and reduce the carbon footprint of agriculture are reflected in a growing interest in climate-smart agriculture (CSA). Specific indicators of productivity, adaptation and mitigation are commonly used in support of claims abou...

A Climate Smartness Index (CSI) Based on Greenhouse Gas Intensity and Water Productivity: Application to Irrigated Rice
Eradicating hunger is a complex and multifaceted challenge, requiring evidence bases that can inform wide scale action, but that are also participatory and grounded to have local relevance and effectiveness. The Rural Household Multi-Indicator Surveys (RHoMIS) provides a broad assessment of house...

Experiences and drivers of food insecurity in Guatemala's dry corridor: insights from the integration of ethnographic and household survey data
Food systems, from the local to the global, face a complex set of challenges in the twenty-first century. As recognized in the latest round of the United National Framework Convention on Climate Change talks, it is clear that global targets for mitigating greenhouse gas emissions cannot be met wi...

Crop models are used for an increasingly broad range of applications, with a commensurate proliferation of methods. Careful framing of research questions and development of targeted and appropriate methods are therefore increasingly important. In conjunction with the other authors in this special...

Improving the use of crop models for risk assessment and climate change adaptation
The development of crop varieties that are better suited to new climatic conditions is vital for future food production1, 2. Increases in mean temperature accelerate crop development, resulting in shorter crop durations and reduced time to accumulate biomass and yield3, 4. The process of breeding...
