CORIGAP: Closing Rice Yield Gaps in Asia

SDC supports the International Rice Research Institute and national research and extension partners in six countries in Asia (China, Indonesia, Myanmar, Sri Lanka, Thailand, Vietnam) to develop quantitative tools and methods to optimize the sustainability of irrigated systems in order to enhance regional food security while minimizing the environmental footprint of rice production. Through this contribution, Switzerland has initiated the development of sustainable rice production indicators which are now adopted by more than 100 private and public organisations.

Rice is the staple food for some 4 billion people worldwide. The availability of low-priced rice is crucial for the food security of 400 million poor people who reside in rice-eating countries

The ‘’Closing Rice Yield Gaps in Asia with Reduced Environmental Footprint (CORIGAP) project’’ started in 2012 with the aim of improving food security and gender equity and alleviating poverty through optimizing productivity and sustainability of irrigated rice production systems.

The practices were integrated to not only increase yield but also increase resource-use efficiency (e.g., water, fertilizer) and reduce their related negative environmental impacts (e.g., soil and water pollution, water depletion, greenhouse gases). These changes were then embeded in a framework of sustainable rice value chain upgrading, linked to markets and policy guidelines. Moreover, in the second phase of CORIGAP, a special focus was put on specific social, economic conditions or constraints faced by smallholder men and women farmers as well as on knowledge factors that play a crucial role in the adoption of best practices.

Objectifs The main objective of CORIGAP is to improve food security and gender and youth equity, and alleviate poverty by optimizing the productivity, resource-use efficiency, and sustainability of irrigated rice production systems and rice value chains.
Groupes cibles Direct:
More than 800’000 farmers in the 6 targetted countries.
Effets à moyen terme

For this third, short phase (April 2021- December 2022), the specific Objectives are:

Outcome 1: Impact and outcomes of and lessons learned from previous phases of CORIGAP documented, published and disseminated.

Outcome 2: Pathways for the agroecological transition towards sustainable food systems designed

Outcome 3: Knowledge products and enhanced capacity used by donors, policy makers, other decision makers and project partners; further scaling of project outputs by partners and transfer of learnings to other regions

Outcome 4: National partners and other projects foster innovations that show positive impact on women and youth.

Principaux résultats antérieurs:  

By December 2020, the project’s efforts on promoting best management practices for lowland intensive rice reached more than 750,000 farmers across six Asian countries (CORIGAP target was 500,000 by 2020). About 120,000 farmers have adopted best practices and increased their rice yield by 11-20%, and profit by 15-25% (target 125,000 by 2022).

In Vietnam, farmers who followed the proposed Best Management Practices; yield were higher than control fields by 0.5 to 1.0 t/ha, pesticide use reduced by 50%, and net income increased by 7-9% in Winter-Spring and 7-18% in Summer-Autumn.

The Sustainable Rice Platform (SRP), which is a multi-stakeholder platform with representation from 100 private sector, government, NGO, and academic organizations haas released a new set of global standards and principles for sustainable rice production.
