On-farm impact of the System of Rice Intensification (SRI): Evidence and knowledge gaps
The System of Rice Intensification (SRI) is being promoted worldwide, but relatively little is yet known about its impacts at farm level. This article reviews available evidence on the impact of SRI practices in terms of yield and productivity. Adoption of SRI practices necessarily changes the mix and allocation of inputs, in particular of water, […]
Comparing productivity of rice under system of rice intensification and conventional flooding: A switching regression approach
Rice (Oryza sativa L.) is one of the most important food crops for more than 50% of the world population (Atera et al., 2018). Globally, about 160 million hectares are estimated to be under rice production with an annual production of approximately 500 million metric tons (Kirby et al., 2017). The demand for rice has […]
SRI 2.0 and Beyond: Sequencing the Protean Evolution of the System of Rice Intensification
SRI has progressed well beyond what it was when first assembled some 40 years ago by Henri de Laulanié, SJ, in Madagascar [1]. It has changed considerably since becoming known outside that country after 2000. Initially, SRI was understood and presented in terms of certain practices, some quite counterintuitive, for improving smallholder production of irrigated […]
An analysis of the adoption of the “system of rice intensification” (SRI): why a homegrown technique has yet to take seed among rice farmers in Madagascar
To combat food insecurity in Madagascar, organizations have promoted the Système de Riziculture Intensifiée (SRI), or System of Rice Intensification, an agroecological rice-growing technique. However, despite its many benefits, adoption remains low (and disadoption remains high) in Madagascar. To better understand these dynamics, we use data from two surveys of 328 rice farming households in southeastern Madagascar […]
Economics of Rice Irrigation Technologies in Kilombero Sub-Basin: A Case of Farming Households from Kilombero in Morogoro, Tanzania
The System of Rice Intensification (SRI) is strongly emphasized by the Ministry of Agriculture in Tanzania to replace traditional flooding. SRI technologies have been scientifically proven to be more efficient in water use than traditional flooding (TFIT). SRI irrigation is therefore a good solution to approach climate change impacts that leads to water stresses, particularly […]
TANZANIA / GLOBAL: Comprehensive Review of the System of Rice Intensification (SRI) to Enhance Productivity and Environmental Sustainability in Rice-Producing Countries
Context The System of Rice Intensification (SRI) is a sustainable rice cultivation method designed to enhance productivity while minimizing resource inputs. It addresses global food security and environmental challenges by improving yield, reducing water use, and mitigating greenhouse gas emissions, particularly in resource-constrained agricultural systems. Objective This review aims to evaluate the core principles of […]
System of Rice Intensification (SRI) as a Sustainable Approach to Enhanced Rice Production
▸ abstract System of Rice Intensification (SRI) is a climate‑smart, input‑reducing and output‑increasing way of growing rice. It focuses on altering management of plants, soil, water and nutrients instead of using external inputs. Developed in Madagascar during the 1980s, SRI has become a worldwide phenomenon because it can help grow more rice by consuming less […]
Spreading the system of rice intensification across East and Southern Africa
SRI is an innovative concept. This new system cannot be considered a “technique”. SRI is more of a philosophy based on good management of the rice plant, the soil and the water conditions. N. Uphoff describes SRI as “an innovation that encourages further innovation”. It is also an ongoing innovation. The system is not a […]
Overview of System of Rice Intensification (SRI) Around the World
During the past several decades, the System of Rice Intensification (SRI) has been validated in 65+ countries in Asia, Africa, and the Americas, with support from NGOs, government agencies, and the private sector. This presentation includes SRI updates from various regions and countries, insights into SRI networks, and a discussion of future trends and directions. […]
SYSTEM OF RICE INTENSIFICATION (SRI) IN MALI
Communities located along the Niger River have very little rainfall—averaging only 150 to 200 mm annually (averages in coastal countries in West Africa are about 1600 mm1 ). Moreover, high climatic variability can significantly raise or lower these levels. Because rice and other crop production depends primarily on the recessional floodwater of the Niger and […]
System of Rice Intensification: Impacts on Crop Productivity and Saving Water in Africa
The System of Rice Intensification (SRI) is a package of practices that changes how rice is grown in paddies, which incredibly increases yields. Rather than fully flooded paddy systems, SRI involves among its practices, the alternate wetting and drying of paddies which saves water, use of less seeds, wider crop spacing, transplanting one seedling per […]
SYSTEM OF RICE INTENSIFICATION (SRI): GROWING MORE WITH LESS WATER Promoting the Adoption of SRI in Kenya
KENYANS WANT MORE RICE The demand for rice in Kenya continues soar as more Kenyans show progressive changes in their eating habits, coupled with urbanization. Rice is currently the third most important cereal crop after maize and wheat. The national rice consumption is estimated at 300,000 metric tons compared to an annual production range of […]
