Abstract: Accurate information on the extent and condition of agricultural crops is critical to the formulation and monitoring of food security policies. Remote sensing offers decision makers the ability to look "wide and often", yet in many areas, persistent cloud cover during the growing season reduces the utility of traditional optical remote sensing techniques. This talk presents recent work on the use of Synthetic Aperture Radar (SAR) to map changes in floodplain vegetation in the Tana River Basin in Kenya as well as rice paddy cultivation in Southeast Asia. The increased availability of free and/or low cost images and processing software is finally putting SAR technology "on the radar" of researchers and decision makers around the world.
