“…The larger, more robust root systems of CA crops and SRI-grown rice plants can better tolerate some water stress and they benefit from the absence of soil compaction and hard pans under CA management. Extended root systems are able to access water in lower soil profiles while reducing the lodging of plants by wind or rain due to stronger anchorage in the soil [34,35]. The combination of SRI and CA can increase benefits from more complex root systems that thrive in aerobic soil with increased moisture retention, resulting in a more efficient use of water and in greater resilience of all crop plants against water stresses.…”

Conservation Agriculture (CA) and the System of Rice Intensification (SRI) are both agroecologically-oriented production systems that support more productive, sustainable, and resource-conserving farming, with synergies arising from their respective assemblages of reinforcing agronomic methods. This review article examines the compatibility between CA and SRI, considering examples of their being utilized in complementary ways. The application of CA principles enhances the growth, yield, and performance of the crops grown under the cropping system as well as the health and resilience of the whole ecosystem. SRI practices create more favorable conditions for the development of crop plants below- and above-ground, including conditions that can be enhanced by CA management. SRI practices such as reduced plant density m−2 can elicit a better phenotypic expression of the genetic potentials of crops grown with CA. For these two agronomic systems to converge at the field level, some of their respective practices for plant, soil, water, and nutrient management need to be modified or aligned. One such adaptation is to practice SRI in CA systems on permanent, no-till, mulch-covered raised beds, with rainfall or irrigation water in the furrows between the beds furnishing and controlling water and providing weed suppression and improved nutrient recycling. SRI rice cropping can benefit from the CA practices of no-tillage, mulch soil cover, and diversified cropping, both in paddies and on raised beds. Several examples have shown that this convergence of cropping systems is feasible for smallholding farmers as well as for larger-scale producers and also that SRI practices within a CA system are amenable to considerable mechanization. Further research and experimentation are needed to identify and assess appropriate practices for capitalizing upon their synergies.

“…The average yields reported from farmers' fields after the FPAR training was in the range of 7-18% more, and average net economic return ranged from 15% to three times more. In comparison to male farmers, women farmers reported higher yields and higher economic returns (Mishra et al, 2019).…”

Given the challenges presented by climate change, water shortage, and land degradation, sustainable agriculture strategies that increase farming systems’ resilience are needed more than ever. This is especially true for sustaining rice production which is the staple food for hundreds of millions of people. Agroecology-based System of Rice Intensification (SRI) is seen as a way forward in transforming food and agriculture systems, especially for the smallholder farmers to build an inclusive, safe, sustainable and resilient society. The findings reported here are based on the engagement that the Asian Center of Innovation for Sustainable Agriculture Intensification (ACISAI), Asian Institute of Technology (AIT), Thailand had in the Lower Mekong River (LMB) basin countries (Cambodia, Laos, Thailand, and Vietnam) using a regional project commonly known as “SRI-LMB”. Using a local, national and regional innovation platform that was designed to systematize engagement and strengthen communication for fuelling innovation, more than 15 institutions were involved in the six-year-long farmers’ participatory action research (FPAR) trial located in the 33 districts of 11 provinces in the LMB. The SRI was used as an ‘entry point’ for such engagement-led-transition. Average yield along with factor productivity increased by more than 50% with a significant reduction in cultivation costs, energy use, and greenhouse gas emission. The purpose of this paper is to share results, and also to detail three key processes that led to innovations in different areas for better adoption: 1. the multi-stakeholder platforms used for action; 2. The FPAR that led to community development; the evidence-based policy and strategies that can support the sustainability of rural livelihoods.
