“…Many agricultural management practices have been developed for mitigating CH 4 and N 2 O emissions from paddy fields[54–56]. Ali et al[57] reported that intermittent irrigation of rice paddies significantly decreased CH 4 emission but stimulated N 2 O emission.…”

“…Ali et al[57] reported that intermittent irrigation of rice paddies significantly decreased CH 4 emission but stimulated N 2 O emission. Kudo et al[56] also reported that mid-season drainage successfully mitigated CH 4 emissions from paddy fields but led to a sharp increase in N 2 O emissions. The results from these studies suggest a trade-off between mitigating CH 4 and N 2 O fluxes from paddy fields.…”

Paddy fields are major sources of global atmospheric greenhouse gases, including methane (CH4) and nitrous oxide (N2O). The different phases previous to emission (production, transport, diffusion, dissolution in pore water and ebullition) despite well-established have rarely been measured in field conditions. We examined them and their relationships with temperature, soil traits and plant biomass in a paddy field in Fujian, southeastern China. CH4 emission was positively correlated with CH4 production, plant-mediated transport, ebullition, diffusion, and concentration of dissolved CH4 in porewater and negatively correlated with sulfate concentration, suggesting the potential use of sulfate fertilizers to mitigate CH4 release. Air temperature and humidity, plant stem biomass, and concentrations of soil sulfate, available N, and DOC together accounted for 92% of the variance in CH4 emission, and Eh, pH, and the concentrations of available N and Fe3+, leaf biomass, and air temperature 95% of the N2O emission. Given the positive correlations between CH4 emission and DOC content and plant biomass, reduce the addition of a carbon substrate such as straw and the development of smaller but higher yielding rice genotypes could be viable options for reducing the release of greenhouse gases from paddy fields to the atmosphere.

“…The largest rice producers are China, India, and Indonesia (FAO 2015). Consequently, they have a higher potential to reduce CH 4 emissions from rice cultivation (FAO 2015) by measures such as optimized drainage (Kudo et al 2014). In sub-Saharan Africa where technological development is low, food losses from agricultural production and postharvest handling and storage can be reduced.…”

Climate change and food security are two of humanity's greatest challenges and are highly interlinked. On the one hand, climate change puts pressure on food security. On the other hand, farming significantly contributes to anthropogenic greenhouse gas emissions. This calls for climate-smart agriculture-agriculture that helps to mitigate and adapt to climate change. Climate-smart agriculture measures are diverse and include emission reductions, sink enhancements, and fossil fuel offsets for mitigation. Adaptation measures include technological advancements, adaptive farming practices, and financial management. Here, we review the potentials and trade-offs of climate-smart agricultural measures by producers and consumers. Our two main findings are as follows: (1) The benefits of measures are often site-dependent and differ according to agricultural practices (e.g., fertilizer use), environmental conditions (e.g., carbon sequestration potential), or the production and consumption of specific products (e.g., rice and meat). (2) Climate-smart agricultural measures on the supply side are likely to be insufficient or ineffective if not accompanied by changes in consumer behavior, as climate-smart agriculture will affect the supply of agricultural commodities and require changes on the demand side in response. Such linkages between demand and supply require simultaneous policy and market incentives. It, therefore, requires interdisciplinary cooperation to meet the twin challenge of climate change and food security. The link to consumer behavior is often neglected in research but regarded as an essential component of climate-smart agriculture. We argue for not solely focusing research and implementation on one-sided measures but designing good, sitespecific combinations of both demand-and supply-side measures to use the potential of agriculture more effectively to mitigate and adapt to climate change.

“…Small reductions in the time during which rice paddies are inundated can substantially reduce methane emissions. However, switching from anaerobic to aerobic production can create the conditions that support nitrification and denitrification, such that nitrous oxide emissions can increase with the change in water management strategy [174,175]. The degree to which methane emissions are reduced and nitrous oxide emissions are increased is largely an empirical issue, which is influenced by soil characteristics and the history of soil and water management in a given location [176].…”

“…The degree to which methane emissions are reduced and nitrous oxide emissions are increased is largely an empirical issue, which is influenced by soil characteristics and the history of soil and water management in a given location [176]. The timing of irrigation and drainage events in rice paddies also can influence methane and nitrous oxide emissions, while also impacting rice yields [174].…”

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.
