“…Furthermore, the traditional method of growing rice involves flooding of rice fields with water and this has been documented to cause anaerobic decomposition of organic matter in the soil, which results in the release of methane, the second major greenhouse gas (USEPA 2006; Khosa et al 2011). Given its low use of water without flooding of rice fields, SRI has been documented to reduce methane emission by 22%-64% (Gathorne-Hardy et al 2013;Suryavanshi et al 2013;Choi et al 2014), making it a useful agricultural practice to mitigate climate change. Studies (Gathorne-Hardy et al 2013;Suryavanshi et al 2013) also show that the global warming potential of traditional rice fields is reduced by 20%-30% trough application of SRI.…”

Improving Welfare Through Climate-Friendly Agriculture: The Case of the System of Rice Intensification

We use rich survey data to investigate the impact of a climate-friendly rice farming method known as the system of rice intensification (SRI) on the welfare of rain-dependent small-holder farmers in Tanzania. SRI reduces water consumption by half, which makes it a promising farming system in the adaptation to climate change in moisture-constrained areas, and it does not require flooding of rice fields, resulting in reduced methane emissions. Endogenous switching regression results suggest that SRI indeed improves yield in rain-dependent areas, but its profitability hinges on the actual market price farmers face. SRI becomes profitable only when the rice variety sells at the same market price as that of traditional varieties, but results in loss when SRI rice sells at a lower price. We argue that the effort of promoting adoption of such types of climate-friendly agricultural practices requires complementary institutional reform and support in order to ensure their profitability to small-holder farmers.JEL Classification: D13, J32, O33, Q12.

Rice production is susceptible to damage from the changes in temperature and rainfall patterns, and in the frequency of major storm events that will accompany climate change. Deltaic areas, in which millions of farmers cultivate from one to three crops of rice per year, are susceptible also to the impacts of a rising sea level, submergence during major storm events, and saline intrusion into groundwater and surface water resources. In this paper, I review the current state of knowledge regarding the potential impacts of climate change on rice production and I describe adaptation measures that involve soil and water management. In many areas, farmers will need to modify crop choices, crop calendars, and soil and water management practices as they adapt to climate change. Adaptation measures at the local, regional, and international levels also will be helpful in moderating the potential impacts of climate change on aggregate rice production and on household food security in many countries. Some of the changes in soil and water management and other production practices that will be implemented in response to climate change also will reduce methane generation and release from rice fields. Some of the measures also will reduce the uptake of arsenic in rice plants, thus addressing an important public health issue in portions of South and Southeast Asia. Where feasible, replacing continuously flooded rice production with some form of aerobic rice production, will contribute to achieving adaptation objectives, while also reducing global warming potential and minimizing the risk of negative health impacts due to consumption of arsenic contaminated rice.

“…1). En el Tolima el 68 % de los municipios (32) presentan un IUA mayor a 0.5, donde el 81.5% de agua es consumida por el sector agrícola y la mayor demanda hídrica está concentrada alrededor de los distritos de riego para el cultivo de arroz (6). Es importante tener en cuenta que el IUA se afecta por: a) la falta de educación ambiental (EA); b) la deficiente aplicación normativa (DAN); c) la poca adopción de tecnologías (AT); d) la contaminación hídrica (CH), y e) la deforestación y la ampliación de la frontera agrícola y pecuaria (DAFAP).…”

El uso eficiente del agua determina el futuro del cultivo de arroz en Colombia frente a los tratados de libre comercio, ya que es un factor que condiciona el área sembrada, el rendimiento de la cosecha y los costos de producción, además de su sostenibilidad en el tiempo. Por lo tanto, se presenta una revisión de las tecnologías desarrolladas a nivel mundial enfocadas al ahorro del agua en el cultivo de arroz en condiciones aeróbicas y anaeróbicas. Se resaltan tecnologías alternativas que superan al sistema convencional en rendimiento y en la cantidad de arroz cosechado por metro cúbico de agua invertido. En la reflexión para Colombia, se destacan aspectos importantes para la construcción de la agenda de investigación y la apropiación social de las tecnologías alternativas con miras a la optimización del recurso hídrico en el cultivo de arroz; se recomienda priorizar el arroz aeróbico y la medición efectiva del consumo de agua, indispensable para controlar su uso, planear, dirigir y entender cómo estas tecnologías alternativas conducen a la recuperación de la inversión de los agricultores y a la rentabilidad del cultivo.Palabras clave: Arroz, tecnologías, uso eficiente del agua, aeróbico, campo inundado. AbstractWater use efficiency, given that it conditions the sown areas, yield and production costs, as well as its sustainability, determines the future of rice production in Colombia against the FDA. This paper presents a review of the globally developed technologies for water saving in rice production under aerobic and anaerobic conditions. The authors highlight alternative technologies that surpass the conventional system in terms of yield and harvest per cubic meter of water used. In the reflection for Colombia, the authors highlight important features for the research agenda and the social appropriation of alternative technologies with a view to optimizing water resources usage for rice production. Recommendations include the prioritizing of aerobic rice and the effective measurement of water consumption, which is indispensable for its use, and for planning, directing, and understanding how these alternative technologies can lead to the recovery of the investment made by agricultural workers and crop profitability.
