'No regret' mitigation strategies in rice production analyzes incentives for scaling up climate change mitigation based on highlighting co-benefits of mitigation options.
The project looks beyond simple water-saving benefits to identify the full range of impacts on smallholder farmers of low-emissions rice production. As such, the project seeks to overcome what has traditionally been one of the largest hurdles to widespread uptake of Alternate Wetting and Drying (AWD), an irrigated rice growing practice that significantly decreases methane production while keeping yields consistent: While the water-saving features of AWD are climate-friendly, these water-saving features do not provide enough incentive to motivate adoption for many smallholder farmers. This project addresses the problem of slow uptake of AWD and other mitigation options by providing an innovative methodology for assessing and strengthening research on all of the ancillary benefits of AWD – what is called ‘no-regret’ mitigation.
The ‘No regret’ project accelerates large-scale uptake of AWD by embracing a large range of stakeholders, from farmers and extension services to national policy makers. At the farm level, the project assesses agronomic impacts in crop performance through participatory field-testing in Climate-Smart Villages. Both women and men farmers – while recognizing their different roles and needs – have equal opportunity to be involved in field testing, evaluation of technologies, and trainings. Training materials are offered in local languages. At the farmer level, the project is exploring whether participatory mitigation selection (PMS) can help farmers decide fon low-emission crop management options that are locally suitable. This also allows quantitative evaluation of the co-benefits of mitigation techniques (agronomic and economic).
The project purposely analyzes gender- and socially differentiated knowledge and perceptions toward climate change to increase understanding about how households process decisions about whether to adopt a new technology. Gendered patterns of interaction and gender-disaggregated data on access to information and level of participation are collected and analyzed, then used to adjust training materials and support decision making. By recognizing that perceptions and attitude toward mitigation options vary across gender and social groups, participatory approaches to communicating information are modified to increase understanding in all of the gender and social groups.
The project also supports Vietnam’s National Action Plans (NAPs) and evaluates potential opportunities to scale-up Nationally Appropriate Mitigation Activities (NAMAs). Additionally, the agriculture sector may integrate mitigation objectives into its modernization campaigns and rehabilitation programs, e.g. for irrigation infrastructure. Distinct links to IRRI’s projects Policy Information and Response Platform on Climate Change and Rice in the ASEAN and its member countries (PIRCCA) and the Climate and Clean Air Coalition (CCAC) - funded Rice Paddy Component ensure well-established networks to be taken advantage of in order to reach out to policymakers. The ‘No regret’ project provides policy makers with field-based evidence on yield and emission changes and analyses of benefits to farmers. By strengthening extension services through trainings and workshops, local policymakers have the information they need to implement mitigation strategies.
Finally, this project also analyzes how synergy may be developed through adoption of mitigation technologies and modernization.
