Proper nourishment is fundamental for satisfactory crop growth and production. However, for efficient crop production, it is important to understand the soil environment, to recognize the limitations of that environment, and to ameliorate them where possible without damaging the soil quality. Soil testing and fertilizer recommendation facilities (STFRF) can help farmers to achieve environmental and economic sustainability by assisting them in recognizing their soil condition, reducing agrochemicals usage, using an appropriate amount of fertilizer, minimizing input costs, and achieving higher yield. These facilities are not new in the context of Bangladesh, yet the adoption rate among farmers is low and its determinants have rarely been empirically tested based on microlevel data. Therefore, this study examined those factors underlying the adoption of soil testing and fertilizer recommendation facilities using field surveyed data of 176 individual farmers. Our evidence shows that young farmers with less farming experience are more likely to adopt these facilities. Additionally, being small-scale farmers, having higher education, having more farming income, and having more knowledge about these facilities and the fees of these facilities were found to have a significant effect on the adoption. On the other hand, gender, land ownership, and secondary income were found to be insignificant with regard to the adoption of soil testing and fertilizer recommendation facilities. Our results also revealed that most adopter farmers not only focused on profitability, but were additionally concerned with environmental well-being.

Insufficient rainfall in the dry season and scarcity of surface water has resulted in firms’ reliance on groundwater for agriculture in the northern part of Bangladesh. Most irrigation systems in the country are diesel or electric, which raises the cost and demand for energy and pollutes the environment. Utilizing the abundant sunshine and disseminating solar-based irrigation systems is expected to be a fittingly rewarding experience for irrigation purposes. Therefore, this study identifies the factors influencing the adoption of solar irrigation facilities (SIFs) and the impacts of their adoption on irrigation cost, return on investment (ROI), and production costs, using survey data collected from 405 rice farmers of Dinajpur district. The study employed three treatment effect estimators, namely inverse probability weighting (IPW), regression adjustment (RA), and inverse probability weighted regression adjustment (IPWRA), to address the potential selection bias issue. The results revealed that farming experience, knowledge, environmental awareness, soil fertility, and irrigation machinery ownership significantly influenced adoption decisions. The treatment effect model result indicated that farmers who adopted this method could minimize irrigation costs by 1.88 to 2.22%, obtain 4.48 to 8.16% higher ROI, and reduce total production cost by 0.06 to 0.98% compared to non-adopters. Our findings suggested that policy interventions targeting scaling up SIFs should consider focusing on government and stakeholders’ greater attention on designing more appropriate schemes through experimentation and multiple iterations.

This study explores the pivotal role of theories of economics in shaping the multifaceted concept of sustainable development and integrates economic, social, and environmental dimensions. It traces the intellectual trajectory of classical, neoclassical, and contemporary economic paradigms, analysing their contributions to sustainability-oriented policies and practices. The study critically analyses key concepts, including equitable income redistribution, resource stewardship, and ecological preservation. It contrasts liberal and dependency theories while also comparing insights from environmental and ecological economics. Employing a rigorous literature review and comparative analytical methodology, the study bridges the theoretical foundations with real-world applications, illustrating the dynamic interplay between theories of economics and sustainability imperatives. The findings elucidate the dichotomy between weak and strong sustainability frameworks, advocating for ethical and interdisciplinary approaches to policymaking. By offering a comprehensive synthesis of the most influential theories of economics and sustainable development practices, this study provides profound insights for policymakers, academics, and practitioners seeking to address pressing global challenges through informed and integrative strategies.

Due to the combined effect of biotic and abiotic constraints, rising population pressure, and inelastic demand in the crop and horticulture sector, Bangladesh has had to adopt heavily subsidized and intensified fertilizer policies to enhance crop productivity, achieve and sustain self-sufficiency in food production, and food security provision. Although the initiative has played a vital role in boosting production, it has also invigorated the unbalanced amount of fertilizer application practices raising questions about maintaining biodiversity and ecosystem services while feeding the nation’s population. Further research in this area must thus be applied to monitor and improve this sector. This study attempts to understand the issue by investigating the factors influencing Boro rice farmers’ adoption decisions of recommended fertilizer doses. The study employs an ordered probit model with a sample selection approach. The investigation is based on collected data from 405 randomly selected farmers using a face-to-face interview method. The farmers were classified into low, middle, high and non-adopter groups. The study revealed that farmers’ age, land typology, soil water retention, knowledge, and availability of cow dung significantly influenced farmers’ decision to apply fertilizers. However, farmers’ carry an aversion to following recommendations for fertilizer application due to their ambiguity about the whole system, their current fertilizer application-seeking behavior, and the lack of understanding of the environmental benefits of adoption. These issues urge policy interventions to initiate village-based demonstration programs that synthesize better synergies between recommended dose adoption, yield amelioration, sustainable soil care, and economics.

To achieve the coveted objectives of sustainable development, the Bangladesh government has devised a comprehensive strategy to promote the adoption of innovative agricultural practices capable of addressing the critical challenges at the inte...
