Food Security and Climate Change in the Asia-Pacific Region: Evaluating Mismatch between Crop Development and Water Availability

This paper looks at how climate change could affect the rate of phenological development — biological events related to climate, such as flowering — and rainfall patterns during the growing season. The authors suggest that these changes may result in mismatch between water demand by crops and water availability from rainfall.

The paper describes a project that combines a new analysis of meteorological data with previously published data on climatic changes to assess the expected consequences of this mismatch for food security.

The authors illustrate how understanding how key crops might be affected by climate change in the Asia-Pacific region can help farmers, community workers and policymakers to prepare and adapt. Strategies include timing of planting, managing rainwater resources, use of new varieties, alternate crops and shifts in geographic distribution of crops.
