According to a report, a new project that aims to maximize rainfed rice production through efficient natural resource management based on seasonal climate prediction was launched under the IRRI-Japan Collaborative Research Project (IJRCP) on 1 October. Climate Change Adaptation through Development of a Decision Support tool to guide Rainfed Rice production (CCADS-RR) will address existing constraints in local rice production in Southeast Asia through the Weather-Rice-Nutrient integrated Decision Support System (WeRise).
It was informed by Dr. Sarah Beebout, deputy division head of the Crop and Environmental Sciences Division that throughout human history, predicting, understanding and responding to weather have been farmers’ biggest challenges. But now, we have the technology to significantly help the farmers. The application that also gives farmers options on the optimum planting times, which variety to plant, and the timing of fertilizer application under current and future climate conditions. One hundred fourteen trainers in Indonesia and Laos have attended training on using WeRise to facilitate technology dissemination.
In a workshop, subject matter was discussed on the importance of impact pathway for WeRise, its various adoption pathways, and what needs to be done to create outcomes, impacts, and benefits. Further, it was also explained the importance of a dynamic rice production, potential area map and the methodology for the development of the map. A researcher of the agro-meteorology division of the National Institute of Agro-Environmental Sciences presented evaluating weather indices during key phase of rice production derived from seasonal climate forecast. It was narrated that since rice is most susceptible to heat stress at the flowering stage, shifting the time of flowering to early morning, when the temperature is cooler, can mitigate the effect of heat stress.
The workshop was organized by IRRI and JIRCAS, 35 collaborators and observers from Indonesia, Japan, Laos, and the Philippines attended the workshop. A stakeholders meeting was also held on 10 September in ICRR, Sukamandi, Indonesia.
