“…Rice production is moderately susceptible to damage from climate change. Rising temperatures and changes in the amount and timing of rainfall can impair plant growth and reduce crop yields [6][7][8]. The increasing atmospheric concentration of CO 2 will enhance plant growth in some areas, with positive implications for crop yield, but the net impact of climate change will be negative in areas where the yield impairment due to rising temperatures or changing rainfall patterns is substantial.…”

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.

“…This will alter the habitat specification of many insect pests, which may find suitable alternative habitats at greater latitudes. Many species may have their diapause strategies disrupted as the linkages between temperatures or moisture regimes and day lengths are altered [2,30]. Genetic variation and multi-factor inheritance of innate recognition of environmental signals may mean that many species can adapt readily to such disruption.…”

“…Evidences suggest that anthropogenic activities lead to an increase in greenhouse gas concentrations especially of carbon dioxide which ultimately leads to climate change. Plant physiological processes directly respond to the various climatic factors such as air and soil temperature, solar radiation, precipitation, relative humidity and wind speed [2,3]. Climate change exerts maximum influence on pests, diseases and weeds [2,[4][5][6][7][8].…”

Impact of climate change on insect pests, plant chemical ecology, tritrophic interactions and food production

Climate change is a major concern for agriculture globally. Dynamic climatic parameters including increased temperature and carbon dioxide have greatly affected crop production. As a consequence of climatic uncertainties, new insect pests have emerged, the crop cultivation practices have changed, and drought and floods have created havoc around the globe. Besides, plant and insecticidal resistance against insects and diseases has got compromised, the diversity and abundance of arthropods has changed, geographical ranges of insect pests have extended far beyond their existing limits and new biotypes have evolved. All these have led to the reduced efficacy of crop protection technologies, huge crop losses, thereby, food insecurity. Although concerted efforts have been made and simulation models have been developed to mitigate the climate change effects on plants, still, most simulation models fail to account for losses due to pests, weeds and diseases. In addition, the monitoring data of insect pests are not available in most of the developing countries and the software models developed for prediction analysis are not effective against insect-pests. This review highlights the possible impacts of climate change on phytophagous insects, chemical ecology, and plant pest interactions leading to food insecurity and the strategies thereof.
