This study conducted a questionnaire-led survey to explore the financial feasibility and socio-environmental impacts of stand-alone solar home systems (SHS) through stratified random sampling. Based on the above consideration, fifteen cases of studies of various watt peak (Wp) capacities have been investigated to evaluate the economic viability of solar home systems. The results revealed that most of the cases have positive net present value (NPV) and low payback periods, with an internal rate of return (IRR) value ranging from 16% to 131%, which signifies a high rate of investment exchange. Solar home systems are economically profitable for micro-enterprises and households with low-income generation activities as opposed to the households using it only for lighting. The study found that solar home systems with a capacity above 30 Wp are the most economically viable option, which can also avoid 6.15 to 7.34 tonnes of CO2 emissions during the 20 years of life-cycle, while providing different applications including lighting, recreation, information, health, and economic benefits.

After ratifying the Framework Convention for Tobacco Control in 2004, Bangladesh enacted anti-tobacco laws, policies, and administrative measures. Evidence suggests that the progress so far has not been significant, and Bangladesh will most likely fail to meet its target to become tobacco-free by 2040. This study undertakes a national-level political economy analysis to explore the dynamics that affect the processes of required tobacco policy reforms and implementation. Based on a desk review of pertinent pieces of literature and key informant interviews, this research examines the political behavior of key individuals, institutional reform initiatives, and the government’s commitment to the tobacco control agenda. The findings indicate that the political will of becoming tobacco-free is explicitly present in key narratives. However, intra-government conflict of interests and incentives, the skewed commitment of government bodies, state-business nexus, incapacity of vital organizations, and the dubious role of key individuals and committees fail to translate this will into active implementation. The article concludes that the idea of tobacco control remains a strategic accommodation, and its implementation requires genuine commitment and wider public support. The government must confer adequate authority and resources to the national tobacco control cell and call for agencies to convene to the common of creating a tobacco-free Bangladesh.
