“…The model results show that water information transparency has a significant positive effect on online consumers’ competence trust ( β = 0.453, p < 0.01), thus, H2a is supported. As Mullick and Das (2021) showed that irrigated Boro rice in Bangladesh has the greatest potential to meet sustainability needs and that people measure food security in terms of water resources (water quantity and quality) and believe that only an environment with few pollutants can have the capacity to provide high quality green agricultural products. Meanwhile, water information transparency also has a significant positive effect on online consumer benevolence trust ( β = 0.368, p < 0.01), and H2b is supported.…”

“…This study concludes that the greater the transparency of information on water sources, the greater the consumer’s trust in the online seller’s ability to deliver. Using rice as an example, research suggests that producers can contribute to food security by growing rice with more efficient irrigation techniques and higher quality water ( Mullick and Das, 2021 ). Online sellers who disclose information about these water sources will encourage consumers to believe that the seller is able to provide quality green agricultural products, the ability to achieve environmental protection, which in turn increases consumers’ trust in the ability of online sellers.…”

IntroductionIn 2020, the outbreak of COVID-19 has forced consumers to shift their consumption patterns online. However, the problem of online fraud in green agricultural products seriously undermines consumer trust and is detrimental to the sustainable consumption of green agricultural products. Therefore, it is particularly important to enhance consumers’ trust in online sellers. This study aims to investigate how the product environmental information transparency(soil information transparency and water information transparency) affects online consumers’ purchasing behavior of green agricultural products.MethodsThis study constructs a theoretical framework of “product environmental information transparency - online consumer trust - online purchase behavior”.We conducted an online randomized questionnaire to collect data from a sample of 512 consumers who had experience buying green agricultural products online fitted a structural equation model (SEM).ResultsThe results show that (1) the two dimensions of product environmental information transparency have different effects on different dimensions of online consumer trust. Among them, soil information transparency has a significant positive effect on competence trust, while it does not have a significant positive effect on benevolence trust. Water information transparency has a significant positive effect on both dimensions of online consumer trust, (2) online consumer trust has a significant positive effect on online consumer purchase behavior, and (3) competence trust has a significant positive effect on benevolence trust.DiscussionOur study shows that consumer trust in merchants is significantly enhanced by increasing the transparency of environmental information about green agricultural products. different dimensions of environmental information transparency have different effects on different dimensions of online consumer trust. Product information transparency is proposed as a tool for producers to use in the online marketing of green agricultural products. Consumers’ access to information can be improved through online public disclosure of environmental quality indicators in the production process of green agricultural products, and ultimately enhance online consumption of green agricultural products.

“…Moreover, cultivating two rice crops per year, particularly with high agrochemical use in the boro season, resulted in the highest GHG emissions per unit of energy input. At the national level, boro season rice has the greatest total water consumption and grey water footprint, an indicator of pollution, despite it occupying lower cropped area than aman season rice, contributing to significant concerns about the sustainability of water resources (Mullick and Das, 2021). These findings underscore the cropping system intensification challenges facing Bangladesh, where prominent trade-offs exist between food production and environmental goals, particularly related to water use and GHG emissions for rice production (Pandey et al 2020;Sapkota et al 2021).…”

Diversification of smallholder rice-based cropping systems has the potential to increase cropping system intensity and boost food security. However, impacts on resource use efficiencies (e.g., nutrients, energy, and labor) remain poorly understood, highlighting the need to quantify synergies and trade-offs among different sustainability indicators under on-farm conditions. In southern coastal Bangladesh, aman season rice is characterized by low inputs and low productivity. We evaluated the farm-level impacts of cropping system intensification (adding irrigated boro season rice) and diversification (adding chili, groundnut, mungbean, or lathyrus) on seven performance indicators (rice equivalent yield, energy efficiency, partial nitrogen productivity, partial potassium productivity, partial greenhouse gas footprint, benefit-cost ratio, and hired labor energy productivity) based on a comprehensive survey of 501 households. Indicators were combined into a multi-criteria performance index, and their scope for improvement was calculated by comparing an individual farmer’s performance to top-performing farmers (highest 20%). Results indicate that the baseline system (single-crop aman season rice) was the least productive, while double cropped systems increased rice equivalent yield 72–217%. Despite gains in productivity, higher cropping intensity reduced resource use efficiencies due to higher inputs of fertilizer and energy, which also increased production costs, particularly for boro season rice. However, trade-offs were smaller for diversified systems including legumes, largely owing to lower N fertilizer inputs. Aman season rice had the highest multi-criteria performance index, followed by systems with mungbean and lathyrus, indicating the latter are promising options to boost food production and profitability without compromising sustainability. Large gaps between individual and top-performing farmers existed for each indicator, suggesting significant scope for improvement. By targeting indicators contributing most to the multi-criteria performance index (partial nitrogen productivity, energy efficiency, hired labor energy productivity), results suggest further sustainability gains can be achieved through future field research studies focused on optimizing management within diversified systems.

“…According to the United States Department of Agriculture (USDA) (2016), 7.21% of the world's rice production amounting to 34.5 million tons has been supplied by Bangladesh alone, and in the future, prolonged dry‐season rice (locally called Boro rice) cultivation is probably expected to represent a considerable part of this enhanced output (Mullick & Das, 2021). During the dry season, the soil water content rapidly decreases, and the water shortage for crop production is primarily met by increased water extraction from the underlying aquifers (Rahman & Hasan, 2016).…”

Climate variability and change significantly influence crop water demand by affecting crop coefficient (K c ), reference crop evapotranspiration (ET o , a grass reference) and potential crop evapotranspiration (ET c ). The climatic effects on these hydroclimatic parameters were investigated in the past mostly for the entire crop growth period, but little or no information is available on their variation over different growth stages of the crops, specifically in Bangladesh. Therefore, this study intended to evaluate the climatic effects on these hydroclimatic parameters at the initial, development, midseason and late-season growth stages of two rice varieties (Bangladesh Rice Research Institute [BRRI] dhan28 and BRRI dhan29) dominantly grown in the dry season in two northeast districts/subdistricts (Sylhet and Srimongal) as well as many other districts of Bangladesh. K c , ET 0 and ET c were analysed for the period from 1994 to 2015 using the analytical approach of the Food and Agriculture Organization (FAO) Penman-Monteith method. The results revealed that the K c of the rice varieties increased in all growth stages over time, with the maximum K c (1.247) in the mid-season stage in Srimongal. ET o and ET c were found to be maximum in the mid-season and late-season stages, respectively. The potential crop water demand (CWR pot ) greatly varied among the initial and development stages and between the two rice varieties. The initial and mid-season growth stages of rice required more water than the other growth stages. The results on the growth stagewise variation of the hydroclimatic parameters pertinent to rice cultivation may greatly contribute to irrigation scheduling for dry-season rice cultivation and planning water resources in the study region.
