Generate evidence of increased farmer profitability through integrated and adaptive research on crop and natural resource management
Optimize integrated, environmentally sustainable rice production systems
Reduce rice yield gaps in lowland rice cropping systems by combining outputs from (1) and (2)
Involve the formal development of Learning Alliances (LA)
The first phase (2012-2016) aimed to sustainably increase rice yields in three major granaries by conducting the following activities:
During Phase II (2017-2020), the project achieved substantial progress through science-based quantitative tools and participatory methods that:
The expected outcomes of CORIGAP Phase III (2021-2022) are as follows:
Environmental/Ecological footprint indicators
Case Study: On-farm assessment of different rice crop management practices in the Mekong Delta (MKD), Vietnam, using sustainability performance indicators
As part of an adaptive research platform, we conducted a household survey of GAP (VietGAP and GlobalGAP), Small Farmer, Large Field (SFLF), and conventional (CNV) farmers in Can Tho province in the Mekong Delta and established replicated production-scale field trials of One Must Do, Five Reductions (1M5R) integrated technology package, with an emphasis on further reducing seed and pesticide inputs by applying limits on their use. We assessed the sustainability performance of 1M5R and the three different management approaches for rice production (i.e. GAP, SFLF, and CNV) over two rice cropping seasons using eight farm-level Sustainable Rice Platform (SRP) performance indicators.

Ecologically-based pest management
A review: Integrated pest management: good intentions, hard realities
In this review, IRRI scientist Rica Joy Flor, co-examined how integrated pest management (IPM) has developed over time and assessed whether this concept remains suited to present-day challenges. The authors believe that despite many good intentions, hard realities need to be faced. They identified the following major weaknesses:
a multitude of IPM definitions that generate unnecessary confusion;
inconsistencies between IPM concepts, practice, and policies; and
insufficient engagement of farmers in IPM technology development and frequent lack of basic understanding of its underlying ecological concepts.
Rice yield gaps
Case study: Sustainable rice production in the Mekong River Delta: Factors influencing farmers’ adoption of the integrated technology package “One Must Do, Five Reductions” (1M5R)
The study aimed to investigate the factors affecting the adoption of sustainable rice farming practices combined in the national program “One Must Do, Five Reductions” (1M5R). Furthermore, a special focus was placed on identifying adoption constraints. Adoption was investigated by means of a survey questionnaire with 465 farmers in An Giang and Can Tho Province. Overall, results show that almost all farmers followed the requirements of pesticide reduction, post-harvest loss reduction, and the use of certified seeds. However, farmers had problems reducing their fertilizer use, water use, and seed rate.
Postharvest loss reduction
Case study: Assessment of post‐harvest losses and carbon footprint in intensive lowland rice production in Myanmar
This paper examines how a move from traditional post-harvest operations of smallholder rice farms in the Ayeyarwady Delta, Myanmar, to improved post-harvest operations affected income, energy efficiency, and greenhouse gas emissions (GHGE). Harvest and post-harvest losses were investigated in a field experiment with 5 replications per scenario. A comparative analysis of energy efficiency and cost-benefits was conducted for different practices of rice production from cultivation to milling.
Case study: Adaptive Research with and without a Learning Alliance in Myanmar: Differences in learning process and agenda for participatory research
The main challenge for researchers and project staff when implementing inclusive approaches in agricultural innovation is how learning and technology adaptation interact and how to reach jointly set targets. We provide a comparative analysis of the learning process induced by adaptive research (AR) in one case and a combined AR with Learning Alliance (LA) approach in another. The AR approach bridged farmers and researchers, but its implementation where researchers controlled experimentation, was not optimally conducive to experiential and discovery learning. The combined AR and LA approach expanded the number of stakeholders with whom farmers interact.

Helena is a Ph.D. Geography student from the University of Basel, Switzerland. Her research focuses on the impact analysis of CORIGAP regarding the environmental and social footprint of rice farmers in Myanmar and Vietnam.
She was under the supervision of Dr. Rita Schneider-Sliwa (University of Basel) and Melanie Connor (IRRI).
Helena is a PhD Geography student from the University of Basel, Switzerland. Her research focuses on the impact analysis of CORIGAP regarding the environmental and social footprint of rice farmers in Myanmar and Vietnam. For the analysis, she is looking at the farmers' socioeconomic structure to connect the dots between the reduction of yield gaps and geographic, economic, as well as demographic factors. The objective is to examine if socioeconomic structure matters to a successful adoption of best management practices and sustainable farming methods. These shall eventually increase yields and hence reduce yield gaps.
