“…If surface storage of rainwater in dugout ponds is encouraged, dependence on withdrawing groundwater might decrease. The conjunctive use of surface water and groundwater is an important strategy to mitigate climate change (Chauhan et al 2014 ). Temperature changes may cause an expansion of weeds, with some species moving to higher latitudes and altitudes (Mahajan et al 2012 ).…”

“…The planting of multipurpose trees on degraded lands helps in C sequestration and reduce the effects of extremely high temperatures (Cannell et al 1996 ). Biochar is another approach to sequester C in terrestrial ecosystems; several associated products are in the process of being manufactured (Chauhan et al 2014 ). Climate change can increase the vulnerability of crops to pest and weed.…”

The emerging uncertainties due to climate change and climatic variability are likely to aggravate the problems of future food security by exerting pressure on agriculture. Simulation models project an increase of 1.8-4.0 °C in global surface air temperatures in the next few decades that will result in large yield reductions in many regions. These increases in temperature will probably offset the likely benefi ts of increasing atmospheric concentrations of carbon dioxide on crop plants. The researchers face an immense challenge of meeting the needs of future generations in the face of both population growth and climate change. The development of climate smart crops needs to be considered on priority as it will make researchers and farmers proactive for the impending adversaries. However, the development of improved cultivars raised to improve yields and enhance adaptation to climate change will have to be complemented by improved crop and agronomic practices. This chapter focuses on the impact of climate change on growth and yield of the food security crops, viz., rice and wheat. Sustainable agronomic and resource management practices that can contribute to climate change mitigation have also been discussed.

“…There is a great concern that Indian rice growers will probably have inadequate access to irrigation water in the future (Mahajan et al, 2013). Hence, shortage of irrigation water, threatens the sustainability of rice production in irrigated conditions (Chauhan et al, , 2014. Rice is mainly cultivated in 38 district of Bihar.…”

“…Higher concentrations of CO2 will increase the yields of C3 crops (e.g., wheat, rice, barley, sugarbeets, and cotton) in some areas, while higher ozone concentrations will have an offsetting, negative impact in others [57]. In large countries such as China and India, the impacts of climate change and the appropriate policy responses and investments could vary substantially across production regions [56,[58][59][60].…”

Food production in 2050 will be sufficient, globally, but many of the poor will remain food insecure. The primary cause of food insecurity will continue to be poverty, rather than inadequate food production. Thus, policies and investments that increase the incomes of the poor will remain the best ways to extend food security to all. Investments that promote growth in sustainable agriculture and provide non-farm employment opportunities in rural areas of lower income countries will be most helpful. There will be sufficient water, globally, to achieve food production goals and sustain rural and urban livelihoods, if we allocate and manage the resource wisely. Yet, water shortages will constrain agricultural production and limit incomes and livelihood opportunities in many areas. Policies and investments are needed to extend and ensure access to water for household use and agricultural production. Challenges requiring the attention of policy makers and investors include increasing urbanization and increasing demands for land and water resources. Policy makers must ensure that farmers retain access to the water they need for producing food and sustaining livelihoods, and they must create greater opportunities for women in agriculture. They must also motivate investments in new technologies that will enhance crop and livestock production, particularly for smallholders, and encourage the private sector to invest in activities that create employment opportunities in rural areas.
