“…In mitigating impacts, it is important to strengthen crop resilience (Walia et al, 2018). Some authors have suggested that conservation agriculture and diversified crop rotation can help preserve food security, restore soil health and thereby minimize the potential effects of global warming (Parihar et al, 2018;Necpalova et al, 2018;Angulo et al, 2013;Burney et al, 2010;Chadwick et al, 2011). These benefits rely on the increased global potential for CO 2 sequestration of soils containing large amounts of organic C. Carbon sequestration appears to be an efficient strategy to boost agricultural production, and to purify surface and underground waters (Lal, 2004;Autret et al, 2016;de Gryze et al, 2011;Tribouillois et al, 2018).…”

Crops, livestock and seafood are major contributors to global economy. Agriculture and fisheries are especially dependent on climate. Thus, elevated temperatures and carbon dioxide levels can have large impacts on appropriate nutrient levels, soil moisture, water availability and various other critical performance conditions. Changes in drought and flood frequency and severity can pose severe challenges to farmers and threaten food safety. In addition, increasingly warmer water temperatures are likely to shift the habitat ranges of many fish and shellfish species, ultimately disrupting ecosystems. In general, climate change will probably have negative implications for farming, animal husbandry and fishing. The effects of climate change must be taken into account as a key aspect along with other evolving factors with a potential impact on agricultural production, such as changes in agricultural practices and technology; all of them with a serious impact on food availability and price. This review is intended to provide critical and timely information on climate change and its implications in the food production/consumption system, paying special attention to the available mitigation strategies.

“…The increasing scarcity of human labor has increased the pressure for the adoption of the machine-driven operations like tillage, sowing/transplanting, harvesting, and threshing (Jat et al 2013). The adverse impact of mechanization and input-intensive agricultural practices on soil quality and environmental pollution are becoming the major current concerns (Parihar et al 2018), demonstrating the need for developing alternative crop management strategies that could minimize the energy use, protect the environment, and maintain comparable or even higher crop productivity over current practices. For such strategic change in production techniques targeting to elevate energy productivity, a detailed input-output energy budgeting is the prerequisite (Tuti et al 2012).…”

Rice-based cropping systems are the most energy-intensive production systems in South Asia. Sustainability of the rice-based cropping systems is nowadays questioned with declining natural resource base, soil degradation, environmental pollution, and declining factor productivity. As a consequence, the search for energy and resource conservation agro-techniques is increasing for sustainable and cleaner production. Conservation agriculture (CA) practices have been recommended for resource conservation, soil health restoration and sustaining crop productivity. The present study aimed to assess the different CA modules in rice-based cropping systems for energy conservation, energy productivity, and to define energy-economic relations. A field experiment consisted of four different tillage-based crop establishment practices (puddled-transplanted rice followed by (fb) conventional-till maize/wheat (CTTPR-CT), non-puddled transplanted rice fb zero-till maize/wheat (NPTPR-ZT), zero-till transplanted rice fb zero-till maize/wheat (ZTTPR-ZT), zero-till direct-seeded rice fb zero-till maize/wheat (ZTDSR-ZT)), with two residue management treatments (residue removal, residue retention) in rice-wheat and rice-maize rotations were evaluated for energy budgeting and energy-economic relations. Conservation-tillage treatments (NPTPR-ZT, ZTTPR-ZT, and ZTDSR-ZT) reduced the energy requirements over conventional tillage treatments, with the greater reduction in ZTTPR-ZT and ZTDSR-ZT treatments. Savings of energy in conservation-tillage treatments were attributed to reduced energy use in land preparation (69-100%) and irrigation (23-27%), which consumed a large amount of fuel energy. Conservation-tillage treatments increased grain and straw/stover yields of crops, eventually increased the output energy (6-16%), net energy (14-26%), energy ratio (25-33%), and energy productivity (23-34%) as compared with CTTPR-CT. For these energy parameters, the treatment order was ZTDSR-ZT ≥ ZTTPR-ZT > NPTPR-ZT > CTTPR-CT (p < 0.05). Crop residue retention reduced net energy, energy ratio, and energy productivity when compared with residue removal. Our results of energy-economic relations favored the "conservative hypothesis," which envisages that energy and monetary investments are not essentially the determinants of crop productivity. Thus, zero tillage-based crop establishments (ZTTPR-ZT, ZTDSR-ZT) in rice-based production systems could be the sustainable alternative to conventional tillage-based agriculture (CTTPR-CT) as they conserved non-renewable energy sources, reduced water requirement, and increased crop productivity.

“…Efficient use of nitrogenous fertilizers saves energy (SDG 7) due to reduction in application of fossil fuel-dependent synthetic fertilizer (Kritee et al, 2015) and also reduces leaching, thereby reducing water pollution (SDG 6 and 14), and hence aids in sustainable production (SDG 12). CSA practices sustain soil health (SDG 2 and 12) (Parihar et al, 2018), save water and increase water productivity (SDG 6) and improve energy use efficiency and energy productivity compared to traditional practices (SDG 7) (Groot et al, 2019). Therefore, to pave the path towards sustainable development of Indian agriculture, scaling up these new activities is a must.…”
