Abstract:
Water security is a fairly new concept in the field of security studies. The global water crisis and human vulnerability as a result of water shortages have heightened the utility of the concept of water security. The Teesta River in Bangladesh has been experiencing water shortages over many years, water security has remained elusive. Recently, China has attempted to resolve the Teesta River water crisis in collaboration with Bangladesh in order to meet its water security challenges. This study attempts to examine the efficacy of the China-led Teesta project on the Teesta River in Bangladesh from the lens of water security.

Abstract:
Bangladesh is losing huge food production from the Teesta catchment area due to a lack of availability of irrigation water in the dry and lean period because of unilateral water withdrawal in the upstream country, India. The area, which is directly dependent on the irrigation water of the Teesta river, is the study area for this paper. The study reveals that rice production in Dalia, Nilphamari, Sayedpur and Rangpur regions is badly affected by the irrigation water scarcity. It appears that production is particularly severely affected in Rangpur, making it a relatively more food insecure area in the Teesta basin. The major finding of this study is that more than 4.45 million metric tons of rice production have been missed from the Teesta catchment area since 2006–07, triggered by the massive irrigation failure of the Teesta Barrage Irrigation Project (TBIP) due to reduced water flow in the Teesta river. The total rice production missed in the north-western region since 2006–07 is more than the country's total rice import during 2008/09–2013/14 fiscal years and nearly one quarter of the total boro production in the 2012/13 fiscal year. This reduced food production renders the north-western part of the country a food insecure region from its own production.

Abstract:
This study seeks to understand the socio-economic and ecological impacts of the hydroelectric power projects along the upper basin of the river Teesta in Sikkim. This study estimates the non-market benefits of restoring the Teesta riverine ecosystem and evaluates the transferability of welfare estimates. This study is a first of its kind undertaken in the Teesta basin which uses a unique dataset of 830 households obtained from the affected regions of the river basin. During the study, nine villages adjacent to the river Teesta, dams, and powerhouses were identified and surveyed. Double bounded dichotomous choice questions were used to elicit willingness to pay (WTP). Both the logistic and normal distribution models were fitted and the results were mostly similar. The median WTP was INR 373.00 and the variables that described the rating on dams, ownership of property, monthly expenditure of the household, informal employment status, and satisfaction about the state of the river Teesta were among the significant variables in the model. The benefit function value transfer estimated was INR 232.00 with the percentage transfer error (PTE) of 61.9%.

Abstract:
Abstract The article presents the role of the newly built reservoir in the formation of the hydrochemistry of water of the Teesta River (a tributary of the Brahmaputra) in its Himalayan course. Field research were performed in the post-monsoon season of the period 2013-2015. Sampling and measuring points were located in five points over 43 km of the Teesta River in the Darjeeling Himalaya. Analysis of water along of river longitudinal profile above and below the reservoir suggest that the reservoir caused decrease most of the basic ions concentrations (Cl−, K+, Na+, Mg2+, NO3− and PO43−). An inverse trend was observed only with respect to Ca2+, SO42− and NH4+. The dam does not influent on the F− concentration. The reservoir causes minor enrichment most of the heavy metals such Cu, Ni, Zn, Cr, Cd and Sr. The lower enrichment of Teesta water below the dam indicates the water self-purification processes for metals by the Teesta Reservoir. The changes of physicochemical properties and concentrations of ions caused by the reservoir are usually normalised by environmental factors before the Teesta River outlet from the Himalayas (within 15 km of the river).

Abstract:
The foreign policy of a country is shaped and influenced not only by the necessity of international environment but also by imperatives of domestic structures and processes. The focus area of the study is primarily Indo-Bangladesh Teesta water deal during UPA-II government. Teesta basin is confronted with a wide range of challenges covering economics, government, and politics to culture, the environment to gender issues to security issues to the health of riverine ecosystems. These concerns, while differing in degree and type, are all tied together by the Teesta, which functions as a common thread flowing through them all and connects them all together. Even though the basin is best known for the lack of a bilateral agreement between India and Bangladesh over water sharing, internal disputes such as the anti-dam motion in Sikkim and the 'Save the Buri Teesta' movement in Bangladesh are also big concerns tied to bilateral trade between the two riparian countries. The study concentrated on the geopolitics of water conflicts in the Teesta basin as well as the role that the TMC party as a domestic factor has played in water negotiations in recent years. The concern of the paper is to examine how a internal domestic considerations of a country act in shaping a country’s foreign policy.

Abstract:
Abstract The aim of this research is to examine the hydropower development potentials and identifying major hydropower projects along the Teesta river basin that is shared by Bangladesh and India. The upstream of Teesta river basin is located mostly in hilly areas of Sikkim where India plans to produce electricity of over 6,500 MW by developing the hydropower potential of the basin. The downstream basin is densely populated, mostly flat land and has no hydropower potential. As of today, Bangladesh and India have been unable to agree on an integrated development plan for the Teesta river basin. Previous negotiations on Teesta river basin management have focused only on sharing water rather than sharing the wide range of benefits from water resources including hydropower. This paper identified the existing, ongoing and upcoming hydropower development projects. The hydropower sharing opportunity exists between the two riparian countries and this type of natural resource development could reduce economic tensions and provide a platform for sustainable agreements.

Abstract:
This study was conducted to monitor the present condition of endangered fishes and productivity of Teesta river closest to Teesta barrage situated in the Lalmonirhat district of Bangladesh. Water and sediment samples were collected twice in a month during the study period from six different (3 upstream and 3 downstream) sites with three replications for each. Required information about threatened fishes was collected from the sampling region associated fishermen and fish markets. The study disclosed over 50 threatened fish species in Teesta river including several threatened fishes namely Bagarius bagarius, Sisor rabdophorus etc. The commonly available endangered fishes were Macrognathus aculiatus, Mastacembelus armatus, Barilius tileo, Raiamas bola, Botia dario, B. lohachata etc. which are rarely available in nationwide. Planktonic flora and fauna determination revealed that comparatively higher density of plankton (n >11500 per liter) as well as more number of planktonic flora (>21 nos.) and fauna (>9 nos.) were monitored in the early monsoon and monsoon season (April-September) and comparatively lower planktonic density (n<10000 per liter) and less number were found in premonsoon season (January-February). The investigation of benthic fauna showed that the riverine ecosystem near to barrage contained 16 species of macro-benthos from different groups. Lastly, it can be noticed that it is very essential to take all effective necessary actions to provide good productivity and conserve the ichthyo diversity of Teesta river that will help to conserve the commonly available endangered and critically endangered fishes of Teesta river.

Abstract:
Abstract The Himalayan rivers are recognized as a reliable source of water supply in the countries of the Hindu Kush Himalayan (HKH) region. Increasing need for food and energy for the growing population of the HKH region has stimulated water harvesting from the transboundary rivers and triggered water conflict, environmental degradation and socio-economic turmoil among the riparian nations. Teesta is one such mighty trans-Himalayan river flowing through India and Bangladesh and is recognized as a basin where there is increasing tension between these two nations. Due to upstream interventions including barrage, dam and hydropower construction, the lower riparian region of Bangladesh faces acute water stresses, which hamper the agricultural, fisheries and livelihood activities of the river-dependent communities and impede the economic prosperity of the greater north-west region. The study provides a robust outline of the transboundary nexus between India and Bangladesh, and identifies upstream intervention-induced economic loss and ecological deterioration in the lower Teesta basin. To encourage water collaboration between the riparian states, the study estimates the benefit of transboundary co-operation for the larger socio-economic prosperity and environmental sustainability in the Teesta basin of the Himalayan region, which is decidedly applicable to similar basins in the HKH region and the rest of the world.

Abstract:
Considering the linkages between climate change and water management, a lack of effort has been observed in analyzing the imprints of climate change over the transboundary Teesta river basin, where the changing climatic conditions can trigger substantial changes in eco-hydrological and socio-politico-economic setups. Therefore, to stimulate effective basin management, we investigated the trends in temperature, precipitation, potential evapotranspiration, and water availability under 1.5 and 2 °C warming levels across the transboundary Teesta river basin. The ensemble median of five bias-corrected model outputs from the Coupled Model Intercomparison Project Phase 6 (CMIP6) was used for this purpose. The results indicate that the temperature is expected to significantly increase (decrease) in the near (far) future, along with an overall significant increasing trend in monsoon precipitation. The evaporation paradox is found in the near future, and the water availability is likely to increase, with some exceptions for the pre-monsoon season. The perpetuation of such changes might result in environmental degradation through snow melting, glacial recession, and floods. Anticipating the changing climatic scenarios and their possible impacts, in this study, we recommend a variety of short- and long-term strategies for the concerned stakeholders to implement the Sustainable Development Goal 13, i.e., “Climate Action”, over the Teesta river basin.

Abstract:
This article describes a hydrologic–economic optimization model for allocating available river flow between competing off- and in-stream demands, based on the marginal benefits (MBs) of sectoral water uses in a segment of the Teesta River in Bangladesh. Irrigation, capture fishery and navigation are the main direct water uses considered. The value of irrigation water was estimated using the residual imputation method. Losses in yield caused by lowered irrigation supply, resulting from reduced river flow, formed the basis for establishing the total and MB functions for off-stream river water use (irrigation). Total and MB functions for in-stream water use (capture fishery, navigation) were developed using field survey data of beneficiaries' income as a function of river flow. Analysis was enhanced by applying AQUARIUS, which allocates water between users to maximize consumer surplus based on MB functions. Model results show that in-stream uses could not compete with off-stream uses in the case of the Teesta, as substantial benefit was obtained from irrigation. Environmental flow to safeguard river health and in-stream use was considered to be a constraint in the optimization, which results in a sizeable reduction in irrigation benefit with a small increase in in-stream benefit. The necessary trade-offs between economic efficiency and environmental protection are depicted, providing insight into a justifiable water allocation strategy for the Teesta.

Abstract:
Heavy rainfall (HRF) forecasting in hilly region is always a challenge to the operational forecasters. Synoptic Analogue Model (SAM) is considered as one of the useful tools for HRF forecasting in topographically influenced hilly regions. In every monsoon season, the Teesta river catchment and its adjoining areas in Sub-Himalayan West Bengal and Sikkim (SHWB-S) generally receive several events of HRF. With the primary objective to find the method to issue HRF warning over Teesta river catchment and adjoining areas in SHWB-S, a SAM has been developed by analyzing 18 years (1998-2015) data comprising prevailing synoptic situations affecting the area and daily rainfall data of subsequent day of HRF. In addition, impact of different synoptic systems on the distribution of HRF has also been studied. The results revealed that there exists a good agreement between daily HRF warnings issued with the corresponding HRF event observed over this region on the next day.

This study anticipates identifying how does climate change affect the livelihood and ecosystem of char land of Teesta River basin char land. Structured questionnaire and related documents were used for both primary and secondary data collection. Survey was conducted in two districts (Rangpur and Nilphamari) and four unions (Lakhitari, Topa Madhupur, Shatibari, Gulmund) of four upazilas (Gangachara, Kaunia, Dimla, Jaldhaka). A total of 50 respondents from each selected char union was selected following a multistage random sampling procedure. Thus, there was altogether 200 respondents selected for this study. Data related to age, education level, occupation, knowledge about climate change of char inhabitants and perception of char dwellers regarding climate change was measured. A total number of 93% of the respondents clearly grasp that climate change refers to changes in long-term typical weather. It was observed that ongoing climate change has 78% impact on agriculture followed by health of peoples and other animals that is 20%. In the rainy season they observed increase in lightning from sun as the highest effect of climate change that has a WAI of 1.77. Teesta river basin people perceived dry spell frequency as the second highest extent of climate change that had a WAI of 1.74 followed by timing of rain offset, uneven distribution of rainfall and timing of rain onset. According to their perception it was found that great extent of loss was found in skills of char peoples (48.35%) followed by knowledge of char peoples (44.27%). It was also observed that a third great extent of loss was found in char peoples good health (41.67%) followed by ability to work (39.06%). Out of all the respondents 166 (43.2%) observed that soil is becoming dry day by day due to climate change followed by rivers becoming dry (37.8%) (Table 8). They found that growing trees have become difficult (45.1%), due to drought underground water is decreasing (61.7%) and air became dry due to climate change, and these are small extent of loss. Char inhabitants observed that climate change impact on physical capital and great extent impact was perceived on people's migration to another place (41.4%). Teesta River basin char dwellers opined about 24 adaptation strategies to reduce the impact of climate change on livelihood and ecosystem in that area.

The objectives of the study were to (i) assess the extent of water shortage in the downstream of Teesta River Basin (TRB) areas; (ii) explore the problems associated with crop production due to water shortage in TRB areas and (iii) examine the impact of water shortage on crop production in TRB areas. The study was conducted in four villages under Nilphmari district during April, 2015. By secondary data analysis and farmers’ perception it was clear that water flow and discharge of Teesta river was decreasing significantly during the last 15 years. The major impact was the dramatic increase in costs of irrigation of major crops and ultimately rise in the costs of production and less profit from farming. All of the farmers (100%) opined that the irrigation costs of major crops have been increasing due to shortage of water. The cultivation of LWRC due to water shortage was also a major impact of water shortage on crop production. Farmers were concentrating more on cultivating maize, tobacco, wheat, different types of vegetables etc. compared to rice particularly in dry season. Different types of problems like increased amount of heavy metal in crop land due to continuous uplifting of ground water, decrease soil fertility, increase pests and diseases to crops, fallowing of high and medium high land, increase of fertilizer and pesticide costs etc. were affecting farmers severely in crop production.SAARC J.

Abstract:
As the world's largest delta, Bangladesh possesses distinctive geomorphology dominated by transboundary rivers, making it vulnerable to climatic hazards such as river erosion that causes severe loss of land and other resources. Using four Landsat imageries of 1991, 2001, 2011 and 2021 the current study analyzed the amount and trend of river erosion and accretion on the Teesta Floodplain of Bangladesh for three decades. Findings indicate that the Teesta River experiences severe bank erosion and accretion regularly, causing bank line shifting and thus significant affecting the land-use/land-cover (LULC) change of the area. Between 1991 and 2021, approximately 194 square kilometers of land were eroded, while an equivalent area of land was accreted. Approximately 1072 km2 of agricultural land was converted into other categories, with the settlement area gradually increasing. This trend of changes shows that agricultural land and water-bodies will reduce in the next two decades while barren land and settlement areas will increase. The agricultural lands and barren lands have a greater chance of being occupied by settlement areas. At the same time, crop production patterns will move to those crops that require less water due to the reduction of water-bodies. Reduced flow during the dry season and massive discharge during the monsoon from India's Gajoldoba barrage caused massive siltation and erosion. Comprehensive river management and restoration with an intergovernmental treaty or understanding between India and Bangladesh is required to resolve this crisis in the long run.

Abstract. The Himalayan region are home to the world’s youngest and largest mountains, and origins of major rivers systems of South Asia. The present work highlight the importance of remote sensing (RS) data based precipitation and terrain products such as digital elevation models, glacier lakes, drainage morphology along with limited ground data for improving the accuracy of hydrological and hydrodynamic (HD) models in various Himalayan river basins such as Upper Ganga, Beas, Sutlej, Teesta, Koshi etc. The satellite based rainfall have mostly shown under prediction in the study area and few places have are also showing over estimation of rainfall. Hydrological modeling results were most accurate for Beas basin, followed by Upper Ganga basin and were least matching for Sutlej basin. Limited ground truth using GNSS measurements showed that digital elevation model (DEM) for carto version 3.1 is most accurate, followed by ALOS-PALSAR 12.5 DEM as compared to other open source DEMs. Major erosion and deposition was found in Rivers Bhagirathi, Alakhnanda, Gori Ganga and Yamuna in Uttarakhand state and Beas and Sutlej Rivers in Himachal Pradesh using pre and post flood DEM datasets. The terrain data and river cross section data showed that river cross sections and water carrying capacity before and after 2013 floods have changed drastically in many river stretches of upper Ganga and parts of Sutlej river basins.

Abstract:
Based on research findings, Bangladesh’s river water, crucial for domestic, agricultural, and industrial use, has long been in a terrible situation. There have been numerous instances of significant contamination in the waterways surrounding Dhaka city, including the Buriganga River, and in Chattogram city, including the Karnaphuli River, over the past 40 years. The existing data demonstrate that other urban rivers, particularly Karatoa, Teesta, Rupsa, Pasur, and Padma, are also in severe condition due to the disposition of huge pollutants. Contaminants flowing with the water have severely polluted the downstream areas of the rivers. High metal concentrations are frequently observed in river water during the dry season. In the Buriganga River and at certain locations in the Turag, Balu, Sitalakhya, and Karnaphuli Rivers, the presence of dissolvable oxygen (DO) is nearly zero. NO3, NO2, and PO4-3 pollution has also occurred in many rivers. Most rivers have Cr, Zn, Fe, Pb, Cu, Cd, Mn, As, and Ni concentrations beyond the legal limit for drinking water. In contrast, some rivers have metal concentrations above the legal irrigation water limit. The majority of the rivers, particularly the peri-urban rivers in Dhaka city, Teesta, Korotoa, Rupsha, Karnaphuli, and Meghna Rivers, have significantly higher metal concentrations, according to sediment data. Metal concentrations in sediment are generally higher than USEPA standards in most rivers. Metal concentrations in fish and crops demonstrate metal bioaccumulation. The trend in metal concentration follows the order of water, fish, and sediment. It has been shown that crops irrigated with tainted water contain dangerous metals. The analysis of daily intake data on carcinogenic and noncarcinogenic substances reveals that consuming contaminated food can seriously impact human health.

Abstract:
Abstract Amblyceps mangois or the “Indian torrent catfish” is a tropical, freshwater, hill-stream species that has ornamental-commercial value and has been included within the “Endangered” category in the list of threatened freshwater fishes of India. A total fourteen populations from the Terai and Dooars region of northern West Bengal, India were analyzed to study the genetic architecture of this species with the help of RAPD and ISSR markers. The observed number of alleles (S), Nei’s gene diversity (H) and Shannon’s information index (H´ or I) showed the highest values in the Teesta river system and the lowest values in the Mahananda river system. The UPGMA-based dendrogram and PCoA, based on RAPD and ISSR fingerprints, showed that the Mahananda and the Teesta river populations formed a group distinct from the remaining Jaldhaka river population. We further considered the fourteen riverine populations into nine groups according to the continuity of the water flow for SHE analysis. It was found that the three components, i.e. the pattern of diversity (H´), richness (S) and evenness (E), have varied and fluctuated across all fourteen populations from higher to lower altitude as the river flows downstream. AMOVA, PhiPT and genetic hierarchical analyses showed that a distinct hierarchical structure is present in Amblyceps populations in the study region. Low levels of genetic diversity/variation and genetic hierarchical structure with high genetic divergence were found in the present study as an indicator of the recent picture of threatened status of this species. This study is the initial attempt to characterize and evaluate the genetic architecture of the species from this region and there is a scope to manage the evolutionary significant units (ESU) for conservation purpose.

Abstract:
In many scientific studies, the r-estimates were widely used to know the spatial distribution of daily rainfall in various weather situations. In this present paper, the cross - correlation analysis has been performed to understand the variability of daily rainfall during monsoon months over Teesta catchment. For the purpose of study, ten station's daily rainfall data for the period 1995-2000 has been utilized. The analysis of estimated cross-correlation field entirely for four months of monsoon suggested that the rainfall area during the monsoon months extends up to 60-80 km distance in north-south, northnortheast-southsouthwest and 50 km in the remaining directions. The pattern of daily rainfall can best be represented as intersection of two ellipses, one with major axis in the direction of northnortheast-southsouthwest (75° N-80° N/115° S-100° S) and another with major axis in northnorthwest-southsoutheast (110° N-120° N/70° S-60° S) direction and are seen traversing in the directions of major uplands. It is also found that the estimated correlation coefficients decreased with distance in all the directions other than in the directions major axes of elliptical patterns of spatial distribution of correlation coefficients and became insignificant beyond 50 km. It is also seen that in hilly regions of the catchment, the moisture feed is blocked further in northnortheast direction (65° N) due to presence of uplands southsouthwest of it.

Abstract:
Abrupt and powerful downpours known as "cloudbursts" can cause disastrous flash floods, landslides, and damage to infrastructure. Twenty-three army troops were washed away and five people killed as a result of the recent flood in Sikkim triggered by a cloudburst over Lhonak Lake in north Sikkim, which overflowed and raised the water levels in the Teesta River. Researchers have created a system based on Convolutional Neural Networks (CNN), weather forecasting, and data mining approaches for weather prediction by modeling meteorological data in order to address the urgent challenge of anticipating and managing cloudburst incidents. The suggested approach in this research describes a real-time cloudburst prediction system that makes use of sophisticated anomaly detection techniques and is based on a machine learning model.

Abstract:
Water resource is rapidly falling short to meet the needs of the population worldwide. The unjust anthropogenic activities have led countries to water stressed/scarce conditions, higher number of hydrological disasters such as floods, droughts and descending levels of groundwater. Being an alpine region, the trans Himalayan region is among the most susceptible regions of the world to the climate change. In this study, the comparative morphometric assessment was made of the eastern and western regions of the alpine zones of the Himalayas. Morphometry of the river basin is a step towards water resource management which provides baseline statistical data about river water. Both river basins were compared using morphometric parameters and further on the basis of 4th order watersheds. The study revealed significant differences in both the basins where the upper Chenab basin has a comparatively higher water discharge, more powerful geological control and lesser basin lag time. The upper Teesta basin demands more management strategies to cope up with higher soil erosion and floods.

Hypoestes phyllostachya Baker (“Polka dot Plant”) is an exotic species that is quite problematic weed of Madagascar origin in Darjeeling and Kalimpong regions of Eastern Himalayan Vegetation. Present study was carried out in 26 different localities covering a vertical distribution from an altitude of 90 msl (Teesta Bazar) to 2,478 msl (Senchal Lake) and horizontal distribution from Rimbik (27.1182° N, 88.1084° E) to Bindu (27.0977° N, 88.8713° E), which revealed its very high invasive potential and ecological amplitude. Its presence in agricultural land together with forest and open land has been a matter of concern as it is creating a threat to the local floras. It was strongly felt that its control measure has to be implemented immediately in order to restore the ecological balance in these local areas.

Abstract:
Energy is crucial for any nation's economic growth and development, as well as poverty eradication and livelihood security. However, hydropower projects require significant expanses of land for construction and also affects people's lives and social structures. Sikkim is a growing economy that is pursuing modernization through economic growth. In Sikkim, the forest department administers 82.31% of the land, while agricultural accounts for 11.1% of the overall geographical area, with agriculture employing 65% of the population. People's livelihoods are adversely affected when agricultural and forest land is diverted for project-related activities. This paper studies the post-project livelihood situations of the affected people of Teesta hydro power project. Field study has been carried out in six affected villages. Total of 334 sample household has been surveyed through pre-structured questionnaire. To assess the levels of various livelihood capital assets, all the five capitals i.e., natural, physical, financial, human and social capitals has been studied at household level by grouping the calculated data into three class intervals (i.e., high, medium and low). Index has been prepared to evaluate livelihood security and the livelihood diversification (Simpson Diversification Index) of the affected villages.

Abstract:
Desilting basins play an important role in run-of-river hydro power projects on Himalayan Rivers. These rivers carry huge amount of sediment with them, due to steep slopes and fragile geology of the region. The suspended sediment enters through the power intake and ultimately the power house. This causes heavy damage to the turbines and other under water parts. Therefore, desilting basins are provided to eliminate suspended sediment from the water conductor system. The design of desilting basin is verified on a physical model for 90% removal of suspended sediment coarser than 0.2 or 0.3 mm and efficacy of flushing tunnel below in transporting the settled sediment. Central Water and Power Research Station, Pune has conducted physical model studies for desilting basin for various hydro power projects in India and neighbouring countries. One such study, Hydraulic model studies for desilting basin for 500 MW Teesta-VI Hydro Electric Project, Sikkim is presented in this paper. Various design parameters such as length of desilting basin, length and bed slope of inlet transition, outlet transition, size of silt flushing tunnel, size and spacing of openings connecting main basin with silt flushing tunnel etc. were tested during the model studies. The results in terms of settling efficiency for 0.3 mm size particles were obtained.

Abstract. We propose an innovative methodology to estimate the formative discharge of alluvial rivers from remote sensing images. This procedure involves automatic extraction of the width of a channel from Landsat Thematic Mapper, Landsat 8, and Sentinel-1 satellite images. We translate the channel width extracted from satellite images to discharge using a width–discharge regime curve established previously by us for the Himalayan rivers. This regime curve is based on the threshold theory, a simple physical force balance that explains the first-order geometry of alluvial channels. Using this procedure, we estimate the formative discharge of six major rivers of the Himalayan foreland: the Brahmaputra, Chenab, Ganga, Indus, Kosi, and Teesta rivers. Except highly regulated rivers (Indus and Chenab), our estimates of the discharge from satellite images can be compared with the mean annual discharge obtained from historical records of gauging stations. We have shown that this procedure applies both to braided and single-thread rivers over a large territory. Furthermore, our methodology to estimate discharge from remote sensing images does not rely on continuous ground calibration.

Katsauksessa käydään läpi suomalainen, matkailuilmiön menneisyyteen kohdistuva tutkimus ja tutkimuksellinen kirjallisuus vuosilta 2004–2023. Tutkimuksia etsittiin tekemällä hakuja Finnassa, Google Scholarissa ja tiedejatutkimus.fi-tietokannassa. Tuloksista suodatettiin pois aihealueeseen liittymättömät hakutulokset. Viimeisen vajaan kahdenkymmenen Suomessa on tehty suhteellisen vähän suoraan matkailun historiaan liittyvää tutkimusta. Esimerkiksi Matkailututkimus-lehden olemassaolon ajalta matkailun historiaa koskevia artikkelia on kaikkiaan kuusi. Määrällisesti suurin yksittäinen matkailun historiantutkimuksen teema-alue viimeisen kahdenkymmenen vuoden ajalta on matkakertomusten ja -kuvausten tutkimus, jolla on muutenkin pitkä traditio. Muita esiinnousseita tutkimusteemoja olivat muun muassa matkailun kehittämisen historia; identifikaatiot, kansallisvaltio ja kulttuuriperintö matkailussa. Lisäksi Suomessa on tehty muuta, teemoiltaan hyvin vaihtelevaa matkailun historian tutkimusta monella eri tieteenalalla. Katsauksen valossa suomalaisessa matkailun historiantutkimuksessa ei ole yhtä dominoivaa teemaa. Esimerkiksi tutkijoiden eläköityminen tai tutkimusintressien vaihtuminen rahoitusinstrumenttien vaateiden tai yhteiskunnan tarpeiden muuttuessa voi näkyä nopeasti matkailuun liittyvän historiantutkimuksen määrässä ja aihevalinnoissa. Matkailun historiasta tehtyjen opinnäytteiden määrä näyttää aikakaudella hieman laskeneen. Uusille matkailun historian tutkimusavauksille olisi Suomessa hyvin tilaa: esimerkiksi ajankohtaiset teemat, kuten kestävyys tai vähemmistökysymykset, huomioivalle matkailun historian yleisesitykselle olisi tarvetta. Lisäksi historiantutkimuksessa yleisesti tapahtuneet muutokset, kuten ylirajainen käänne tai digihistorian nousu, tarjoavat mahdollisuuksia uusille tulkinnoille koko matkailun historiasta.

Abstract:
Although recurrent floods cause detrimental impact for the people living in riverine floodplains, households are taking up various risks management strategies to deal with them. This paper examined household’s post-disaster coping strategies to respond and recover from riverine floods in 2017. Data were collected through a questionnaire survey from 377 households from the right bank of Teesta River in Bangladesh. Households employed different coping strategies including borrowing money, assets disposal, consumption reduction, temporary migration, and grants from external sources, to cope with flood. Results from logistic regression models suggested that increasing severity of flood reduced households’ consumption. Exposed households were more likely to borrow money. Consumption reduction and temporary migration were mostly adopted by agricultural landless households. Income from nonfarm sources was found to be an important factor influencing household’s decisions on coping. Furthermore, households that recovered from the last flood disaster seek insurance through their own savings and available physical assets, highlighting the role of disaster preparedness in resilient recovery. This study calls for the policy intervention at the household-level to enhance the adaptive capacity of riverine households so that people at risk can cope better and recover from flood disaster using their resources.

AbstractDisaster risk perception and risk appraisal are essential in formulating an appropriate disaster risk reduction policy. This study examines the actual vs perceived drought risks by constructing risk indices at the household and expert levels using survey data from the lower Teesta River Basin in northern Bangladesh. The survey data were collected from 450 farmers using a structured questionnaire conducted between August and September 2019. A composite drought risk index was developed to understand households’ perceived and actual risks in the designated areas. The results show that the actual and perceived risk values differ significantly among the three case study sites locally known as Ganai, Ismail, and Par Sekh Sundar. The risk levels also differ significantly across the households’ gender, income, occupation, and educational attainment. People with insolvent socioeconomic status are more prone to drought risk compared to others. Results also reveal that the mean level of perceived risk agrees well with the actual risk, whereas females perceive comparatively higher risk than their male counterparts. Expert views on drought risk are similar to the individual household level perceived risk. The outcomes of this study would assist the policymakers and disaster managers to understand the concrete risk scenarios and take timely disaster risk reduction actions for ensuring a drought-resistant society.

Abstract Here, a regional climate model (RCM) RegCM4 and Coupled Model Intercomparison Project phase 5 (CMIP5) global climate models (GCMs) such as Coupled Physical Model (CM3), Coupled Climate Model phase 1 (CM2P1) and Earth System Model (ESM-2M) with their representative concentration pathway (RCP) datasets were utilized in projecting hydro-climatological variables such as precipitation, temperature, and streamflow in Teesta River basin in north Sikkim, eastern Himalaya, India. For downscaling, a ‘predictor selection analysis’ was performed utilizing a statistical downscaling model. The precision and applicability of RCM and GCM datasets were assessed using several statistical evaluation functions. The downscaled temperature and precipitation datasets were used in the Soil and Water Assessment Tool (SWAT) model for projecting the water yield and streamflow. A Sequential Uncertainty Parameter Fitting 2 optimization algorithm was used for optimizing the coefficient parameter values. The Mann–Kendall test results showed increasing trend in projected temperature and precipitation for future time. A significant increase in minimum temperature was found for the projected scenarios. The SWAT model-based projected outcomes showed a substantial increase in the streamflow and water yield. The results provide an understanding about the hydro-climatological data uncertainties and future changes associated with hydrological components that could be expected because of climate change.

Abstract:
The Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement 2013 Act (RFCTLARR Act) ensures that the ‘public’ is an integral part of the Social Impact Assessment (SIA) process. The law now mandates thattheir opinions would be considered in the report through a public hearing of the affected families. However, the inclusion of the affected people is often questioned in developmental projects such as hydropower projects, especially in hilly areas where the local people whose land is acquired are completely dependent upon it for their livelihood. Their resistance is also depicted through collective social action as aresult of their former experiences with the outcomes of public projects, due to which the public and private companies conducting the SIA studytend to neglect their views. The aim of this paper is to examine the role of public and its inclusion in the SIA process in India, using a case study methodology focusing on the SIA report of Teesta-IV hydroelectricproject submitted in 2018. Following a secondary data based approach, this study will argue that the local tribal communities do not equate the construction of dams with the concept of sustainable development. However, this does not cease the construction of those projects, thereby, questioning the notion of inclusionofthe local people. It is,therefore,recommended that the agencies involved in conducting the process of SIA must take into consideration the conflicting views of the affected families and train theirconsultants to be responsible legally and ethically for project approvals, thereby fostering accountability in the process of development.
