The findings show rising dry-season water demand, severe groundwater decline, weakening aquifer recovery, and an approximately three-quarter reduction in Teesta River flow from the 1979 baseline, increasing dependence on groundwater and energy for irrigation. The study estimates substantial annual economic losses from water scarcity and argues that continued depletion will become increasingly costly. It proposes the Basin Bankruptcy-Adjusted Allocation (BBAA) framework and recommends managed aquifer recharge, ecological-flow protection, demand management, drought-tolerant agriculture, improved monitoring, transboundary cooperation, and climate financing to address water scarcity and prevent further depletion.

The findings confirm a long-run cointegrating relationship among the variables, with an error correction term of −0.916, indicating a 92% annual speed of adjustment. Investment is statistically significant in both the short and long run, while trade openness is significant only in its contemporaneous short-run form. Remittances, however, have no statistically significant impact on GDP per capita growth in either the short run or the long run.

Hadi, Kazi Shawon This study examines the relationship between consumer purchase intention and spending capacity in Bangladesh’s domestic tourism sector. Data were collected from 330 domestic tourists using a structured questionnaire and analyzed through several statistical methods, including factor analysis, OLS, and GLM regression. The findings show that destination preference, destination satisfaction, purchasing power, and previous visit experience significantly affect tourists’ total expenditure. Tourists with higher education, older age, and higher income also tend to spend more on trips. The study suggests that improving tourism infrastructure, destination quality, facilities, and marketing strategies could help increase domestic tourist spending. Overall, the research connects consumer behavioral factors with economic spending behavior in Bangladesh’s emerging tourism market.
