... Over a period of four years (2016–2019), we quantify the benefits accrued to the uptake of SRI among smallholder farmers in Oluch irrigation scheme western Kenya. Our comparisons are in reference to a baseline study conducted prior to the full-scale promotion of SRI in the study area. Our study findings reveal that the uptake of specific SRI practices increased by at least 30–80%, and acreage under rice farming increased by 50%. Although SRI required more production costs per acre (as much as 63% increase), SRI had at least 28.6% higher return per shilling invested. Our findings underscore previous results in the literature that SRI is associated with not only productivity but also economic benefits justifying the need for scaling especially among smallholder farmers.

Black farmers in Jubilee Justice’s program grow the crop using SRI. They’re also reclaiming rice farming as their foodways in the heart of Louisiana, about 100 miles north of Baton Rouge, lies the rain-soaked farm that lured Konda Mason is the founder of Jubilee Justice, a nonprofit that helps small-holder Black farmers in the South grow specialty rice with the System of Rice Intensification (SRI), a “dry-land” method developed in the 1970s and 1980s. Instead of growing rice in flooded paddies to prevent weeds from overtaking the crop, SRI farmers treat rice like a vegetable, irrigating it as needed and using other weed control methods.
For Mason, rice represents a way to transform lives and reclaim the past, offering a path toward racial, economic, and climate justice.Jubilee Justice’s rice program, called the Black Farmers Cohort, currently consists of 10 farmers from Louisiana, Alabama, Georgia, South Carolina, North Carolina, and Kentucky
Identifying rice management interventions to reduce methane emissions while improving productivity is critical for climate change mitigation, adaptation, and food security. We leverage site-based data to model combined rice yields, methane emissions, and water productivity for 83 sites across the Red River Delta, Vietnam. We test three rice management interventions with our coupled crop-soil model, characterized by Alternate Wetting and Drying (AWD) and other System of Rice Intensification (SRI) principles. Our simulations are forced with historical as well as future climate conditions, for a high-emission climate scenario centered on 2050.
We evaluate the efficacy of these interventions for combined climate change mitigation and adaptation under historical and future climate change. Two SRI interventions significantly increased yields (one by over 50%) under historical climate conditions while also reducing (or not increasing) methane emissions. These interventions also increase yields under future climate conditions although climate change decreases absolute yields across all management practices. Generally, where yield improved, so did crop water-use efficiency. However, impacts on methane emissions were mixed under future climate conditions. SRI principles combined with high-yielding varieties, implemented for site-specific conditions, can serve climate change adaptation and mitigation goals.

Periodic rice health inspections are an essential part of agricultural production management in Vietnam, especially in advanced models like high-quality, low-emission rice. For the model in Cần Thơ, periodic inspections ensure rice meets high-quality standards as well as helping optimize cultivation practices to minimize emissions. This approach not only brings economic benefits but also contributes to environmental protection. Thanks to advanced techniques such as the System of Rice Intensification (SRI), efficient water management, and the use of organic fertilizers, the rice is not only thriving but also helping to reduce harmful emissions. The 1 Million Hectare Rice Program in Cần Thơ promises to bring about positive changes and create new opportunities for farmers and Vietnam’s agricultural sector. -- Vijafarm Limited Company

The Community of Hope Agriculture Project (CHAP) is implementing Climate Smart Agriculture under the Livelihood Innovation Food Security Entrepreneurship (LIFE) Project with funding from Irish Aid through Concern Worldwide Liberia. The project, which began in Grand Bassa, Liberia, during 2023 and extended to Rivercess in February 2024, is currently working with 25 smallholder farmers per community, which comprises a total of 214 smallholder farmers who are being introduced to the System of Rice Intensification (SRI) for rice cultivation.
Since the introduction of the SRI in Grand Bassa County, farmer groups like the one in Crayton Estate, have been able to grow rice twice in a year with less external inputs. The resulting SRI adoption has proven sustainable for farming thus far and is achieving high yields. In addition to SRI methods for production, CHAP has created a market for the SRI farmers’ out-grower scheme across the country in support of the “I love Liberian rice” domestic rice production in keeping with the Ministry of Agriculture’s National Agriculture Development Plan (NADP), which includes cultivation of 50,000 ha of lowland rice across the country from 2023 to 2030.

Understanding the System of Rice Intensification (SRI) begins with a distinction between its principles, which are general, and the practices that give effect to these principles when applied, which are and adapted for particular situations. This makes SRI more like a menu than a recipe. It is not something to be promoted by rote learning, glossing over the reasons for its principles and practices of SRI, but rather something that emerges from an understanding of agronomic processes.
Put in simple straightforward terms, SRI management elicits the growth of more robust and more productive plants, i.e., phenotypes, from a given crop variety, i.e., genotype. Application of SRI’s principles and practices evokes the fuller expression of plants’ genetic potential than do most currently prevailing practices, such as high plant density, continuous flooding, and ignoring the contributions of the soil biota and the implications of profuse root growth. This paper enumerates and elucidates the agronomic principles and practices of SRI, considering how and why they achieve the effects that are widely and consistently observed.

The Directorate of Environment has introduced the System of Rice Intensification (SRI) to reduce GHG emissions and improve agricultural productivity in Phayeng village where a project to transform the village to a carbon-positive eco model village is in progress. Twenty-one farmers covering about 12 hectares of land were selected based on their interest and field conditions for a pilot study of SRI. Recent changes in the climate are affecting the Phayeng ecosystem services in terms of agricultural sectors and food insecurities.
A high potential is seen in SRI to help secure livelihoods and to enhance resilience to expected adverse impacts of climate change. SRI can be applied with both irrigated and rain-fed rice systems. The most vulnerable people and vulnerable economic sectors like agriculture will be given attention on priority basis.

This study assesses the impact of three cultivation methods (wetland, SRI, and direct seeding) on the biochemical properties and bacterial communities within the rice rhizosphere across three key growth stages: tillering, flowering, and maturity. The results deepened our understanding of how different cultivation practices influence plant-microbe interactions and their implications for overall rice productivity and soil health. Soil organic carbon (SOC), microbial biomass carbon (MBC), dehydrogenase, substrate-induced respiration (SIR), and metabolic quotient (MQ) were assessed along with high-throughput 16S rRNA sequencing of rice rhizosphere soils.
The rice rhizosphere soil under the SRI registered the highest SOC, MBC, and dehydrogenase followed by wetland and least in direct seeded aerobic cultivation. Cultivation methods caused notable shifts in the abundance of Proteobacteria, Bacteroidetes, and Chloroflexi, while crop growth stages affected the abundance of Proteobacteria, Actinobacteria, Cyanobacteria, Firmicutes, Chloroflexi, and Bacteroidetes. Based on these results, the SRI method brings higher diversification to the rhizosphere bacteriobiota, as well as greater incorporation of carbon into the soil and increased dehydrogenase activity compared to the wetland and aerobic rice.
The impact of climate change on methane (CH4) emissions from rice production in the Coimbatore region of Tamil Nadu was studied utilizing the closed-chamber method for gas collection and gas chromatography analysis. This study identified differences in CH4 emissions between conventional cultivation methods and the system of rice intensification (SRI). Experimental data were subsequently used to guide parametrization and validation of the DeNitrification–DeComposition (DNDC) model.
The validated model was then used to develop future CH4 emissions projections under various shared socio-economic pathways for the mid- (2021–2050) and late (2051–2080) century. The analysis revealed a potential increase in CH4 emissions for the simulated scenarios, which was dependent on specific soil and irrigation management practices. Conventional cultivation produced the highest CH4 emissions. The findings underscored an urgency to develop climate-smart location-specific mitigation strategies focused on simultaneously improving current water and nutrient management practices. This research also highlighted the critical interaction that exists between agricultural practices and climate change, and emphasized the need to implement adaptive crop management strategies that can sustain productivity and mitigate the environmental impacts of rice-based systems in southern India.

Thanks to Khidhir Abbas Hameed, a long-time member of the global SRI community, for continuing to expand the borders of the SRI world.
Rice consumption in Angola, like in many other African nations, is rising due to shifts in eating habits and population growth. The surge in consumption combined with low domestic production and productivity has led to a consistent rise in rice imports. In 2021 the State Treasury of Angola spent over US$260 million on rice imports.
During a February 2024 African Paddy Rice Greenhouse Gas Mitigation workshop, Eng. Carlos Francisco Canza, Angola's focal point within the Coalition for African Rice Development (CARD) from the Rural Extension Department at the Ministry of Agriculture and Forestry, learned about SRI. Elielda Lopes Fernandes, the Tony Blair Institute (TBI) Manager for Food and Agriculture in Angola, was also interested in SRI, and with SRI-2030 knowledge materials, they transplanted the rice seedlings in early July 2024 following SRI principles, marking the first known experimentation of SRI methods in Angola.
