Zeroing-in on drought-stressed rice areas
Tageting our breeding and extension work on severely affected drought areas in rainfed rice ecosystems has just become easier!
IRRI scientists, Dr. Murali Krishna Gumma, Dr. Andy Nelson, and Dr. Samarendu Mohanty used the case of Odisha, India to identify stress-prone villages using time series satellite imagery.
Using satellite data from 2000-01 to 2010-11, the information generated will guide rice scientists and planners in developing technologies suited to rainfed conditions and other rice ecosystems as well as in targeting technologies adapted to local needs. Moreover, the information could be used to develop stress-adaptive measures and technologies focusing on the most vulnerable areas where drought is most severe and where rainfed rice production is the major livelihood of farmers.
This technology will help farmers often vulnerable to drought and flood reduce their losses by using improved varieties and appropriate crop management technologies.
