The PIRCCA project stems from the recognition of the important role of rice for food security in the ASEAN and the specific vulnerabilities of rice production to climate change.
The diverse nature and wide geographic spread of rainfed environments make it essential that research be carried out in partnership with NARES, drawing on local scientific expertise and farmers’ indigenous knowledge. We are a platform within which NARES and IRRI researchers can partner together with farmers and extension workers to tackle key problems at sites representative of the diverse ecosystems.
Rice thrives in hot and dry to humid climates. However, extreme heat episodes can irreversibly damage rice yield, grain quality, and plant processes such as germination and fertilization.
Rice is highly susceptible to heat stress, particularly during the reproductive and ripening stages. Extremely high temperatures, even for a few hours, during flowering can cause complete sterility, while high temperatures during ripening can lead to reduced grain filling and poor milling quality (i.e., more broken grains). And, in combination with other constraints such as lack of water, canopy temperatures can increase even further.
The Mekong Delta is Vietnam's main rice area and accounts for half of annual rice production.Use of rice land in the Delta is divided into agro-hydrological zones controlled by flood duration and depth, water availability, and salinity regimes.
The global rice information gateway aims to provide real-time crop information, medium-term supply and demand outlook, policy briefs, and comprehensive rice data sets at the national, subnational, and household level.
