Green Solutions: Analyzing Financial and Environmental Benefits of Solar Irrigation Pumps in Drought-Affected Regions of Bangladesh

This study aims to evaluate the economic and environmental advantages of solar irrigation pumps (SIPs) in drought-impacted regions of Bangladesh, utilizing primary data gathered from the northern districts of Rajshahi and Bogura. For analysis, this study assessed economic feasibility, examined cost effectiveness, and identified environmental benefits of adopting SIPs in the study area. Using the problem confrontation index approach, the study also identified the key barriers to SIP adoption. Estimated results indicated that the shift from diesel to SIPs has led to considerable fuel savings and cost reductions, demonstrating that SIPs are financially viable with high returns on investment and net present value. Environmental advantages encompass a substantial reduction in greenhouse gas emissions, as well as decreases in carbon monoxide, particulate matter, and black carbon emissions. This study indicates that obstacles such as elevated installation prices, substandard and insufficient equipment, absence of financial and institutional support, lack of awareness, and risk of severe climatic events hinder the adoption of SIPs in the drought-affected regions of Bangladesh. This paper proposes that solar irrigation system as a climate-smart and environmentally sustainable irrigation technique should receive substantial subsidies. Private investors ought to engage in promoting solar irrigation and increasing incentives.
