“…It is important to identify integrated options that create synergies between food systems and public health, and reduce trade-offs between food and climate mitigation such as reducing food loss and food waste (Beddington et al, 2012;Watts et al, 2015Watts et al, , 2020. Governments ought to develop the appropriate policy and strategies, and provide technical and institutional support and incentives to farmers and community to adopt the right, sustainable solutions including appropriate cropping patterns, agronomic management, and sustainable use of resources, including conservation of ecosystems and reduction of fossil fuels (Meybeck et al, 2012;Shepon et al, 2018;Bhatt et al, 2019;Everard et al, 2020).…”

“…The excessive use of agrochemicals and the unsustainable use of groundwater and energy have contributed to high GHG emissions, water pollution, air pollution, water scarcity, energy scarcity, the loss of biodiversity, and grave impacts to human health (Dholakia et al, 2013;Gould, 2018;Pretty et al, 2018;Aryal et al, 2020;Hussain and Qamer, 2020;Fan et al, 2021). It is critical to enhance sustainability in agriculture and build resilience in the production, processing, and trading of food to minimize GHG emissions and optimize the management of water, air, soil, and ecosystems essential for production of food in sustainable manner and supplying of healthy nutritious food for public health (Pretty et al, 2018;Bhatt et al, 2019;Barbier and Burgess, 2020).…”

“…Governments in South Asia ought to increase investment in agriculture and the food system in general to improve efficiencies, including resource use efficiency, in every aspect of the food system to increase productivity, reduce yield gaps, and conserve resources (Beddington et al, 2012;Pretty et al, 2018). Choosing locationally suitable cropping patterns and appropriate agronomic measures, including crop rotation and multi-cropping practices can improve land-use efficiency and crop productivity while generating environmental co-benefits by decreasing dependence on chemical fertilizers and fossil fuels (Bhatt et al, 2019;Tenzin et al, 2019).…”

Climate change has begun to ravage agriculture and threaten food security in many parts of the world. The novel coronavirus pandemic (COVID-19) has further disrupted agricultural activities and supply chains and has become a serious threat for public health. Like in many developing countries, South Asian farmers are now facing the double challenge of addressing the impacts of a changing climate and managing the disruptions caused by COVID-19. Despite growing concern, there is limited understanding of how climate change, public health, and COVID-19 interact, and of the possible pathways to achieving a climate-friendly recovery from COVID-19 to achieve food and nutrition security. In view of this, this paper explores the multifaceted challenges that farmers are now facing in South Asia due to climate change and the disruption caused by COVID-19 from the agricultural and food security lens. The analysis reveals that the complex interactions of COVID-19 and climate change have impacted all dimensions of food security. These interlinkages demand an integrated approach in dealing with food, public health, and climate change to harness synergies and minimize trade-offs between food production, public health, and climate mitigation. I present a framework to address the immediate challenge of COVID-19 and the longer-term challenge of anthropogenic climate change. Key elements of the framework include the strengthening health sector response capacities, strengthening of local and regional food systems, making agriculture resilient to pandemics, adopting flexible and smart approaches—including the implementation of climate-smart agricultural interventions on different scales, promotion of appropriate research and innovation, and the integration of short-term support to address the challenges of COVID-19 to build long-term productivity, and resilience of food systems by investing on natural capital. This framework would enable policy makers to choose the appropriate policy responses at different scales, to address these twin challenges of COVID-19 and climate change.

“…The new contexts that appeared around the world in the recent years changed the paradigm of the economic sector organization and call for novel ways of farm management [151]. The rice-wheat cropping systems concern particularly the researchers [152], specifically in South Asia [51], because of its importance for the food security [153] and the problems associated with the soil quality, water scarcity, and availability of some production factors, such as labor [154].…”

The innovative technologies developed in the different fields of science (nanotechnology, artificial intelligence, genetic modification, etc.) opened new and infinite possibilities for the several stakeholders that carry out their activities in the different economic sectors. For agriculture, these new approaches are particularly relevant and may bring interesting contributions, considering the specificities of the sector, often dealing with contexts of land abandonment and narrow profit margins. Nonetheless, the question in these unstopped evolutions is about the interlinkages with sustainability. In this context, the objectives of this study are to highlight the main insights from the available scientific literature about the interrelationships between the new trends in the agriculture and the sustainability. To achieve these aims, a search on the Web of Science Core Collection (WoS) and Scopus databases was carried out, on 15 May 2021, for the topics ‘smart agriculture’ and ‘sustainability’. A total of 231 documents (102 from WoS and 129 from Scopus) were obtained, remaining 155 documents after removing the duplicated, which were surveyed through systematic review following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approach. As main insights, the concerns of the researchers with the impacts on the sustainability from the transformations in the farming organization are highlighted. On the other hand, it was shown the relevance and the new opportunities, including in terms of food supply, arising from the precision agriculture, agricultural intelligence, vertical/urban farming, circular economy, internet of things, and crowdfarming. We suggest the new and wider concept of ‘integrated-smart agriculture’, better than ‘climate-smart agriculture’.

“…Crop yields are generally lower due to higher salt contents but now requires attention for feeding the ever increasing population (Lal, 2015;Wang et al, 2020). For which soil testing and scheduling fertilization thereof, is the only way towards judicious use of fertilizers, thereby increasing fertilizer use efficiency (Bhatt et al, 2020;Singh et al, 2019) and sustainable agriculture (Bhatt and Singh, 2020a,b). Degradation of soil health, lowering down of water table, diminishing soil organic matter status, increase in insect-pest and diseases attack and deficiency of micro-nutrients are some of the sustainability issues (Bhatt et al, 2016).…”

Aim: To delineates micro and macro nutrients along with physico-chemical properties of Ratte-Khera farm of Punjab Agricultural University (PAU), Ludhiana, Punjab, India for effective use of nutrients. Methodology: Thirty two soil samples were collected during 2019 from eight different location using GPS from different soils depths viz.? 0-15,15-30, 30-60 and 60-90 cm in the problematic water logged soils of Ratte-khera farm. Further, GPS maps were also prepared pertaining to different depths for the judicious use of fertilizers in the region.? Parker nutrient index was also evaluated for different nutrients for the region. Results: Around 87.5% of the samples had normal pH (6.5 -8.7) and 12.5% soils were with pH on higher side with higher range of EC, lower range of SOC, higher and potassium. About 87.5 % samples were in higher available-phosphorus. Further, lower and higher range of DTPA zinc and copper observed in samples while 25 and 37.5% recorded with lower range of DTPA iron (Fe) and manganese (Mn). Correlation analysis revealed? availability of Fe is positively associated with Mn, P, Cu and Zn in the soil. Interpretation: Soils of Ratte-Khera farm reported to be saline (white alkali soils) with normal range of pH (no need to add any gypsum or lime). Final recommendation is to apply 25% higher dose of nitrogenous (N) and phosphatic (P) fertilizers with no need for potassic fertilizers. Further, micro-nutrients should be applied as and when symptoms observed on the field crops.
