“…The congenial growth conditions prevailed because AWD under SRI method allowed the rice plant to have a greater number of phyllochrons, increased number of tillers, and highly developed roots, before the flowering phase ( Deb, 2020 ) and produced highest grain yield over all the rice production techniques evaluated. Our findings were in accordance with the findings of Chapagain and Yamaji (2010) ; Mishra and Salokhe (2011) , and Nazir et al.…”

IntroductionConventional rice production techniques are less economical and more vulnerable to sustainable utilization of farm resources as well as significantly contributed GHGs to atmosphere.MethodsIn order to assess the best rice production system for coastal areas, six rice production techniques were evaluated, including SRI-AWD (system of rice intensification with alternate wetting and drying (AWD)), DSR-CF (direct seeded rice with continuous flooding (CF)), DSR-AWD (direct seeded rice with AWD), TPR-CF (transplanted rice with CF), TPR-AWD (transplanted rice with AWD), and FPR-CF (farmer practice with CF). The performance of these technologies was assessed using indicators such as rice productivity, energy balance, GWP (global warming potential), soil health indicators, and profitability. Finally, using these indicators, a climate smartness index (CSI) was calculated.Results and discussionRice grown with SRI-AWD method had 54.8 % higher CSI over FPR-CF, and also give 24.5 to 28.3% higher CSI for DSR and TPR as well. There evaluations based on the climate smartness index can provide cleaner and more sustainable rice production and can be used as guiding principle for policy makers.

“…The higher IWP and EWP in the SRI method are due to the fact that farmers who adopt this approach generally save more water and produce more rice. SRI proponents suggest the use of cono-weeders for weeding and soil aeration, but poor farmers find the equipment to be too expensive and struggle to use it in field conditions [72].…”

Rice is a water-guzzling crop cultivated mostly through inefficient irrigation methods which leads to low water use efficiency and many environmental problems. Additionally, the export of virtual water through rice trading and the looming water crisis poses significant threats to the sustainability of rice production and food security. There are several alternative rice production methods to improve water use efficiency. These include aerobic rice, direct-seeded rice (DSR), alternate wetting and drying (AWD), saturated soil culture (SSC), drip-irrigated rice, a system of rice intensification (SRI), and smart irrigation with sensors and the Internet of Things (IoT). However, each method has its own advantages and disadvantages. For example, drip-irrigated rice and IoT-based automated irrigation are not feasible for poor farmers due to the high production costs associated with specialized machinery and tools. Similarly, aerobic rice, drip-irrigated rice, and the SRI are labor-intensive, making them unsuitable for areas with a shortage of labor. On the other hand, DSR is suitable for labor-scarce areas, provided herbicides are used to control weeds. In this article, the suitability of different water-saving rice production methods is reviewed based on factors such as climate, soil type, labor, energy, and greenhouse gas emissions, and their prospects and challenges are evaluated. Additionally, the article examines how cultural practices, such as seed treatment, weed control, and nutrition management, contribute to enhancing water use efficiency in rice production.

“…Several local landraces of aubergine, sesame, and mustard have become CR, grown in only a handful of small farms in the district (Table 3). The ancient practice of growing the mustard landraces, Jhanti and Tori, between rows of rice in the Rabi season (Deb 2020) has also become obsolete, owing to the prevalent practice of rice monoculture.…”

The decimation of biodiversity at the species, genetic, and ecosystem levels as a direct consequence of the industrial resource use mode is well documented in human ecology and conservation literature. Not only wild biota but also domesticated crop landraces have been pushed to extinction by industrial land-use systems. The process of biodiversity erosion impinges on, and is augmented by, the decimation of local cultural elements, such as food cultures, the vocabularies of local languages, house architecture, and an inchoate appreciation of the non-use value of biodiversity, i.e., beyond its instrumental value. This process of biocultural erosion is evident in the district of Bankura, West Bengal, India, and this article collates evidence from over two decades of my research on the biodiversity and cultural elements of the region. The replacement of a traditional eco-centric ethic with an industrial ethic, and its consequent impacts on biodiversity and local cultural traditions in this region, is illustrative of the global process of biodiversity loss.
