“…For each of the jetties that were built, a boat association was established that manages the operation of the tourist boats [12,33]. Association membership is only available to people from Siltation refers to the contamination of water due to the presence of fine particles of soil or sediment, mostly consisting of silt or clay [43] b Eutrophication is the condition when there is an overabundance of plant and algal development caused by an increase in the availability of one or more growth elements that are essential for photosynthesis, such as sunshine, carbon dioxide, and nutritional fertilizers [44] that village and to those who own boats. Many of the communities don't own boats.…”

Ecotourism, over time, has emerged as a preferred strategy for resource utilization within protected areas of developing nations, as it effectively bridges the gap between ecological conservation imperatives and the imperative for local economic development. This study aims to comprehensively analyze the multifaceted impacts of ecotourism on local communities, with due consideration given to its environmental, social, and economic dimensions. Furthermore, the research endeavors to evaluate the degree of stakeholder engagement in fostering sustainable tourism practices within ecotourism initiatives. Thematic content analysis has been used and the data for the analysis has been sourced through field observations, key informant discussions and different secondary sources. This research examines the dynamic interaction between local communities and ecotourism aspects in the Chilika Wetland in India, using the DPSIR (Driver-Pressure-State-Impact-Response) framework. It promotes a comprehensive decision-making method that considers the Triple Bottom Line and Community-oriented Collaborative approach. Findings underscore the potential for Chilika’s ecosystem restoration and mitigating adverse tourist impacts with effective ecotourism governance. The need for collaboration among stakeholders becomes crucial for the effective administration of ecotourism, as shown by the instance of Mangalajodi, which exemplifies the successful outcome of community-led ecotourism. Nevertheless, certain prerequisites, such as knowledge dissemination, training, financial support, cultural promotion, eco-friendly infrastructure, and a commitment to conservation, have been recognized as necessary for ensuring long-term community involvement in ecotourism initiatives.

“…Additionally, tree debris may be an important component of the floods and debris flows in forested watersheds. Regardless of the sediment production mechanism, deposition occurs when the transport capacity of the flow is not sufficient to transport the material due to changes in velocity, which itself is caused by changes in slope, resistance to flow, or presence of obstacles [28][29][30][31].…”

Floods are frequent hydro-meteorological hazards which cause losses in many parts of the world. In hilly and mountainous environments, floods often contain sediments which are derived from mass movements and soil erosion. The deposited sediments cause significant direct damage, and indirect costs of clean-up and sediment removal. The quantification of these sediment-related costs is still a major challenge and few multi-hazard risk studies take this into account. This research is an attempt to quantify sediment deposition caused by extreme weather events in tropical regions. The research was carried out on the heavily forested volcanic island of Dominica, which was impacted by Hurricane Maria in September 2017. The intense rainfall caused soil erosion, landslides, debris flows, and flash floods resulting in a massive amount of sediments being deposited in the river channels and alluvial fan, where most settlements are located. The overall damages and losses were approximately USD 1.3 billion, USD 92 million of which relates to the cost for removing sediments. The deposition height and extent were determined by calculating the difference in elevation using pre- and post-event Unmanned Aerial Vehicle (UAV) data and additional Light Detection and Raging (LiDAR) data. This provided deposition volumes of approximately 41 and 21 (103 m3) for the two study sites. For verification, the maximum flood level was simulated using trend interpolation of the flood margins and the Digital Terrain Model (DTM) was subtracted from it to obtain flooding depth, which indicates the maximum deposition height. The sediment deposition height was also measured in the field for a number of points for verification. The methods were applied in two sites and the results were compared. We investigated the strengths and weaknesses of direct sediment observations, and analyzed the uncertainty of sediment volume estimates by DTM/DSM differencing. The study concludes that the use of pre- and post-event UAV data in heavily vegetated tropical areas leads to a high level of uncertainty in the estimated volume of sediments.

“…The weathering of rocks is an ongoing common process that shapes the earth's surface and controls the biogeochemical cycles, and thereby regulates monsoon patterns. Although Dal Lake has been subjected to many studies by several workers (Jeelani and Shah 2006 and references there in), few investigations on Wular Lake are available which were mainly focused on hydrogeology and environmental aspects (Kulkarni et al 2009). The present work is a maiden attempt on the geochemistry of lake sediments by authors.…”

Major and trace element geochemistry of lake sediments, India: implications for weathering and climate control

et al. 2014

Climate plays an essential role in weathering of rocks, and a rich record of climatic change is preserved in rocks and sediments. The physical and chemical weathering also largely depend on climate prevailing in the area, apart from other factors. In an attempt to understand the dominance of physical over chemical weathering processes, the textural and geochemical studies of Wular Lake sediments from Jammu and Kashmir, northern India, have been taken up in the present study. These sediments documented several attentiongrabbing processes that operated during weathering, transportation, and deposition. Investigations have revealed that physical weathering dominated over chemical weathering, resulting in enhanced rates of erosion and consequent deposition of large detritus into the lake. Lake sediments and source rock chemistry are comparable, indicating low to moderate chemical weathering history of the source region which is consistent with cold regions and steep slope areas. Unusual enrichment of Cr values in sediments compared with source rocks signify a process of sediment-water interaction where Cr is removed from water and preferentially adsorbed onto clay fraction of sediments.
