“…In addition, the abandonment of the actual itinerary of cultivation techniques by farmers, as popularized by the technicians who are responsible for monitoring the farms, is confirmed by at the level of the managed lowlands in Dano. In Benin, rice farmers believe that rice intensification systems (RIS) should be adapted to local production conditions to increase yields (Gbenou and al., 2016).…”

In terms of irrigated agricultural production in Burkina Faso, rice is the second most important crop after maize. This rice production is supposed to satisfy domestic demand and reduce imports, which has an impact on the country's trade balance. However, the rice sector is faced with climatic and technical productivity constraints. Indeed, the variability of temperatures and rainfall over the period 1988-2018, with its corollaries of drought and flooding episodes, has an impact on agricultural activity. The objective of this study is to analyze the effect of the dynamics of climatic parameters as well as the effectiveness of technological packages on rice productivity in Sissili Province. To this end, a methodology based on the quantitative approach was adopted. It is based on the collection, processing, and analysis of numerical data on key climatic parameters from the Pô synoptic station from 1988 to 2018. These data were correlated with those available on rice production over the same period. The analyses show that Sissili Province is marked by alternating rainfall deficits and surpluses, which have an impact on rice production, the evolution of which is out of phase with the increase in planted areas. This suggests that increasing the area planted seems to be an alternative way of compensating for a possible drop in rainfall. Under these conditions, the development of lowlands and water reservoirs represents opportunities for the diversification of production systems.

This meta‐analysis evaluated the impact of agro‐ecological practices and water management techniques on lowland rice yield and water productivity (WP). A total of 573 observations were collected from 56 articles that met specific criteria from 445 publications. Five water management practices were assessed: continuous flooding (CF), soil saturation (SS), moderate (AWDm) and severe (AWDs) alternate wetting and drying, and the aerobic rice system (ARS). The response ratios (RRs) of yield and WP were compared for crop management, soil fertility, weed control and evaporation. The integration of agro‐ecological practices such as short‐cycle rice varieties, crop rotation, organic nutrient application and mechanical weeding with water management led to similar yields across CF, SS, AWDm and AWDs, with ARS consistently yielding the lowest yields. However, medium‐ and long‐cycle varieties under AWDs experienced yield losses of 11 and 13%, respectively. Mineral fertilizer combined with AWDs resulted in a 14% lower yield than did CF. Mechanical weeding increased the rice yield and WP by 10 and 10% in SS, and only WP by 35% in AWDs, whereas chemical weeding decreased the yield by 13% in AWDs. Crop rotation enhanced yield and WP by 13 and 12%, respectively, under AWDm compared to that under CF. WP was greater under AWDs (36%) and AWDm (12%) than under CF.

Core Ideas System of rice intensification increases crop productivity with lesser inputs. System of rice intensification yields more productive and robust rice phenotypes from given plant genotypes. System of rice intensification crops are tolerant to biotic/abiotic stresses and it reduces GHGs from rice fields. System of rice intensification enables farmers to adapt to and mitigate climate change. This paper reviews how and why SRI can be considered as climate‐smart agriculture. Although there has been controversy over some of the high yields reported with the System of Rice (Oryza sativa L.) Intensification (SRI), an agroecological crop management system developed in Madagascar, substantial increases in average rice yields have been reported from more than 50 countries when these methods are used, not even necessarily fully. Most attention thus far has focused on yield and little on whether or how SRI methods can help farmers adapt to and buffer the adverse stresses of climate change as well as reduce their rice paddies’ contribution to global warming. According to FAO criteria, achieving all three impacts would qualify SRI as “climate‐smart agriculture” (CSA).This paper reviews how making SRI modifications in agronomic practices can elicit plant phenotypes from given rice genotypes that are more robust and adaptive as well as more productive. This effect appears to result from SRI's inducing larger, healthier root systems and enhancing beneficial soil biota. These effects are associated with improvements in a variety of morphological and physiological characteristics in rice plants. Cross‐national meta‐analysis has documented reductions in crop water requirements and increased water productivity under SRI management. These methods are also seen to contribute to greater drought‐tolerance, resistance to storm damage, cold‐temperature hardiness, shortened crop cycles that reduce crops’ exposure to biotic and abiotic stresses, less susceptibility to insect pest and disease damage, and diminished net emissions of greenhouse gases from paddy fields. The efficacy of SRI management methods is increasingly accepted by governments, donor agencies and farmers, but more remains to be researched and evaluated.
