Regional climate reports

Background

As background for a wide variety of subsequent activities, including agricultural impacts modelling, the CCAFS program requires information about what is currently known about recent climatic trends in the three initial target regions, the current state-of-the-art with regard to projections from existing climate models for these regions to the end of the current century, and developments in climate modelling in the next five years that may increase our knowledge of how climate may change in these regions in the coming decades.

Objectives

Objectives of the work are reviews that accomplish the following:

1. An outline of current trends in climate and extreme events (such as the frequency of hot and cold days and nights, heavy rainfall events, and droughts) in each region, from the middle of the twentieth century onwards, as far as this is possible.

2. An evaluation of the CMIP coupled climate models’ climatologies for the three regions, and assessment of their projections from the 2030s to the 2090s, in the light of indicators and diagnostics that are related to agricultural production impacts and food security considerations.

3. A brief indication of how the science of climate modelling may develop in the next five years that could increase knowledge of changes in climate and climate variability in the three regions in the decades leading up to the middle of the century.
