Abstract

Agricultural resources, such as nutrients and water, are significant limiting factors to productivity. Resource-use efficiency is thus crucial for a better and more stable rainfed rice production, now and in the future, especially with anticipated changes in climate. A third of the world’s rice-growing area is rainfed and are greatly affected by abiotic stresses. To increase rainfed rice production, weather forecasts will be useful to farmers so they can plan ahead.

Since 2010, the IRRI-Japan Collaborative Project has been developing the Weather-Rice-Nutrient Integrated Decision Support System (WeRise) as a decision-support tool for climate change adaptation in rainfed rice areas. The tool interfaces IRRI’s crop- and nutrient-management models with the Japan Agency for Marine-Earth Science and Technology (JAMSTEC)’s global seasonal weather forecast (SINTEX-F) model.

In the seminar, Keiichi will present and discuss the progress made and challenges encountered in developing WeRise.
