Climate change mitigation and adaptation
Rice production has been threatened by climate change, with effects of higher temperatures, more frequent droughts and flooding, and sea-level water rise that affects mega-deltas and coastal zones. Rice-based farming systems are now driven to develop and test innovations that adapt to changing climates and mitigate greenhouse gas emissions.
An achievement of RICE Phase I is the dissemination of climate-smart technologies in Asia that can reduce methane emissions by 50%. By 2022, RICE aims to extend technologies to more households for increased adoption of improved rice varieties and farming practices that reduce agriculture-related greenhouse gas emissions in rice-based farming systems.
More than two years after Typhoon Haiyan devastated the island of Leyte in the Philippines, the survivors, especially the farmers, are still struggling to rebuild their lives. Green Super Rice (GSR) is giving them a fighting chance.
Climate-smart rice varieties developed at IRRI and multiplied and distributed under the Stress-Tolerant Rice for Africa and South Asia (STRASA) project, are already creating a major impact and have improved the lives of 10 million farmers in South Asia and Africa.
CGIAR scientists wielding big data tools to blunt the impacts of climate change on Latin America’s rice production have been named one of two winners of the Big Data Climate Challenge at the recent United Nations Climate Summit held in New York City, U.S.A.
Two new cold-tolerant varieties, FOFIFA 183 and FOFIFA 184, were released for the high-altitude rainfed lowland rice ecosystem through activities of the Africa Rice Center component of the Stress-tolerant Rice for Africa and South Asia (STRASA) project, which is funded by the Bill & Melinda Gates Foundation.
Aiming to help farmers adapt their rice farming practices to climate change, the CLUES project (Climate change affecting land use in the Mekong Delta: Adaptation of rice cropping systems) could not have come at a better time.
A growing number of subsistence farmers as well as seed growers are now planting “climate-change-ready” rice in the rice bowl state of Uttar Pradesh and the speedy uptake is unprecedented.
In mitigating and adapting to climate change, RICE aims to:
- Help at least 17 million more households to adopt improved rice varieties and/or farming practices by 2022 and a further 19 million by 2030.
- Increase water- and nutrient-use efficiency in rice-based farming systems by at least 5% by 2022, rising to 11% by 2030.
- Help reduce agriculture-related greenhouse gas emissions in rice-based farming systems by at least 28.4 megatons carbon dioxide (CO2) equivalent/year by 2022 and by a further 28.4 megatons CO2 equivalent/year by 2030, compared to business-as-usual scenarios.
