To improve the prediction of crop yields at an aggregate scale, we developed a data assimilation-crop modeling framework that incorporates remotely sensed soil moisture and leaf area index (LAI) into a crop model using sequential data assimilation. The core of the framework is an Ensemble Kalman ...

Assimilation of remotely sensed soil moisture and vegetation with a crop simulation model for maize yield prediction
Climate prediction on decadal time scales is currently an active area of research. Although there are indications that predictions from dynamical models may have skill in some regions, assessment of this skill is still underway, and reliable model-based predictions of regional ‘near-term’ climate...

The CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) is using theory of change (TOC) planning to specify research outputs, partnerships needed to produce outputs, and a plausible hypothesis on how these outputs will contribute to development outcomes. This learning ...

Lessons in Theory of Change from a Series of Regional Planning Workshops
Growing awareness of how development outcomes are dependent on our variable and changing climate is focusing increasing attention on the role of climate information in agricultural development. Much of this attention is driven by the growing acceptance that human activity is altering the Earth’s ...
Our project explaining seasonal forecasting to farmers in central Senegal built common ground between scientific forecasting and traditional knowledge. It helped farmers understand and use seasonal forecasts to improve crop strategies, and let farmers explain to meteorologists what seasonal clima...
