Singh, V.P. | Tuong, T. P. and Kam, S. P.
The literature reveals that rainfed rice environments have been characterized for various purposes at differing scales using a range of techniques. This chapter reviews the biophysical aspects of characterization undertaken in rainfed rice environments, more specifically at sites of the Rainfed Lowland Rice Research Consortium. It presents the status of the work done; provides an inventory of techniques applied; discusses scale, variability, and accuracy pinpoints gaps in knowledge; and provides future directions for work from which these sites can benefit. The chapter brings out commonalities of characteristics across rainfed sites, provides insights into which issues new technological developments should focus on when addressing major limitations to production enhancement, and identifies opportunities for making future work more efficient and relevant to needs. Examples for each of these aspects are drawn from case studies in the rainfed rice regions, and specific cases where environmental characterization has made a significant impact on national systems are cited.
