“…The construction of the barrage on this river across the border to divert its flow of water has badly affected the efficacy of the Teesta Barrage Project. According to Water Development Board, Bangladesh got only about two per cent of the required quantum of water from the border last year [7]. The release of such low quantum of water was adversely affecting navigation, irrigation, fishery and ecology of the lower Teesta riparian area of Bangladesh [8].…”

People repeatedly confronted by natural catastrophe in almost every year such as drought and flood in the lower Teesta Basin area. After the construction of two barrages in Gozaldoba and Dalia on Teesta River drought and flood occurs almost every year. Intensity and frequency of these calamities are also increasing in an alarming rate, which caused serious damage to livelihoods and economy of this area. The objective of this paper is to find out the drought and flood induced vulnerability in the study area through Strength Weakness Opportunities Threat (SWOT) analysis. By this we can summarize the current state of a space and helping to devise a plan for the future, one that employs the existing strengths, redresses existing weaknesses, exploits opportunities and defends against threats. The study is conducted in Charkharibari village of Tepakharibari union of Dimla upazilla in Nilphamary district and Jigabari village of Tepamadhupur union of Kaunia upazilla in Rangpur district, taking the locational advantage, flood and drought proneness, topographic nature and population diversity under consideration. The study population is finite and sample size was determined by using Kothari’s formula. Sample size for Charkharibari and Jigabari is 200 and 85 respectively; samples were drawn through Simple Random Sampling (SRS) procedure. The relevant data and information used in this study have been collected from both primary and secondary sources. Primary data has been collected through a questionnaire survey and couple of Focus Group Discussions (FGD’s) with a view to collect quantitative as well as qualitative data. Results from Strength Weakness Opportunities Threat (SWOT) analysis shows that, between the two villages severity of drought and flood is higher in Charkharibari village. After comparing the strengths Jigabari is ahead; comparing weakness, opportunities and threat Charkharibari is ahead. Based on the analysis and the findings, it is evident that in terms of vulnerability Charkharibari is more vulnerable than Jigabari. But there are more opportunities for Charkharibari than Jigabari. However, it is evident that proper dissemination of information regarding early warning and assistance from government as well as non-government organizations can significantly improve the coping capacity of people.

The Teesta basin, shared by Bangladesh and India, undergoes profound changes due to land use and land cover (LULC) dynamics combined with climate change, significantly impacting its water balance. This comprehensive study aims to analyze the combined effects of future LULC changes and climate change on basin runoff. Employing a cellular-automata model, we accurately predicted LULC for 2020 and projected scenarios for 2050 and 2080. We utilized the semi-distributed Soil Water Assessment Tool (SWAT) hydrological model for the base period (1995–2014) and two future periods: 2050s (2035–2064) and 2080s (2071–2100). SWAT model is forced by 8 General Circulation Models (GCMs) under two Socioeconomic Pathways (SSPs): SSP245 and SSP585. The study reveals notable LULC changes, with substantial increases in agricultural (0.49%) and settlement areas (1.67%) from 2000 to 2010, followed by changes from 2010 to 2020. The CA-Markov prediction indicates significant future increases in settlements and agricultural land by 2050 and 2080, coupled with reductions in forest, water, and snow cover. The calibrated and validated SWAT model effectively simulated discharge, yielding satisfactory results. Projected changes in discharge during the monsoon and winter periods were examined under different scenarios. Monsoon discharge is predicted to increase by 26–38% in the 2050s and 30–45% in the 2080s. Conversely, the winter/dry period may experience a decrease of 46–49% in the 2050s and 38% in the 2080s for SSP245 and SSP585 scenarios, respectively. Considering LULC changes to account, additional discharge increases during the monsoon are projected, with slight increases in the dry period during the 2050s and decreases during the 2080s. This study anticipates an increasing trend in peak flow during the monsoon and a declining trend in mean flow during winter without further upstream water control. Understanding and managing the combined effects of LULC changes and climate change on the hydrological dynamics of the basin is of utmost importance for sustainable water resource management in the region.
