“…Ecosystem engineers can alter an ecosystem through biomanipulation (Triest et al, 2016) and can have a significant impact on the landscape of an area. Although widely accepted as a cost-effective environmental restoration technology (Biswas, 2021), phytoremediation is still an emerging technology that has to prove its effectiveness on a field scale. However, risk-based pilot projects on bank stabilization in a small, vulnerable river stretch may be demonstrated by planting soil binding, ecologically suitable species (McGregor et al, 2018; Wollny et al, 2019; Oberhagemann et al, 2020).…”

The Gangetic Dolphin (Platanista gangetica) was once found in tens of thousands in the rivers of the Indian sub-continent, but the numbers have now dwindled abysmally throughout its geographical distribution. In northeastern India too, dolphins were seen in all the major rivers and also in certain wetlands during monsoon months till the early 1980s. However, the sighting of dolphins is rare now due to natural and human-induced factors. Three factors - adequate water cover, water quality, and abundance of prey food either individually or in combination- relate to River Dolphins’ existence. Variability of meteorological parameters also severely impacts on the limno-biological parameters of riverine habitats. Restoration of Gangetic Dolphins in their traditional habitats can boost ecotourism in the region. An extensive study is necessary to assess the cumulative impact of the proposed hydroelectric projects on the aquatic biodiversity of the entire eastern Himalayan region. The need of the hour is to adopt a holistic and participatory approach for maintaining riverine health and the prey base of the Barak and the Brahmaputra systems.

“…Arcenas (2017) [70] showed several ways for stakeholder engagement and community involvement including turning the monitoring process into communication products for the relevant stakeholders, helping them to be engaged and involved in basin management. Biswas (2021) [71] mentioned that a collective approach that involves stakeholders in the joint management of the watershed is considered the best option to ensure livelihood sustainability and the eco-restoration of the catchment areas. Gilman et al (2004) [72] stated that the basic premise of IRBM is that the stakeholder should participate in the process and the conservationist can benefit from the lessons shared by the IRBM's practitioners based on their history of stakeholder engagement.…”

To address water-related issues of river pollution, floods, droughts, and ecological water allocations, there is a need for an integrated river basin management (IRBM) plan for the successful management of all the river basins in the country. Stakeholder engagement is one of the important elements for the effective implementation of IRBM. In this study, a systematic bibliometric analysis has been successfully carried out to identify the trends, patterns, and research gaps in the establishment of stakeholder engagement frameworks in IRBM. Three renowned scientific databases were used to quantitatively assess the published literature on stakeholder engagement. The search contributed by providing a clear understanding and mechanisms for an effective stakeholder engagement, thus highlighting the research gap, whereby there is a lack of an effective stakeholder engagement framework for IRBM. Based on the analysis results, it was found that many pieces of literature have been written about the implementation of IRBM, including the importance of stakeholder engagement or participation. However, there is very limited study on how effective stakeholder engagement could be carried out to enhance water management at the river basin level. The findings also recorded that stakeholder engagement can serve as a form of social learning, and leadership plays a significant role in ensuring the effectiveness of stakeholder engagement in IRBM. From the review analysis, it was concluded that further research studies need to be carried out at the river basin level to formulate an effective stakeholder engagement framework for the sustainable management of water.

“…Streambank erosion and channel planform dynamics are two important hydrogeomorphic processes that play a significant role in the evolution of fluvial landforms 1 – 3 . Large sediment pulses generated by hillslope processes, bank incision and channel migration have been considered a potential threat to the aquatic and terrestrial biota 4 , 5 . As a result, the high concentration of heavy metals and nutrients in streams and river sediments, which occur via accelerated bank erosion and hillslope processes in many fluvial systems, has been attributed to an increase in urbanisation and intensified agricultural activities 4 , 6 , 7 .…”

Bank erosion is an important source of sediment and phosphorus to inland fluvial systems and is generally responsible for more than half of the total watershed sediment export. Numerous studies have quantified bank erosion and the spatio-temporal variation of sediment flux in different watersheds. However, there is sparse research to date on the linkages between bank erosion/accretion and sediment export under different land uses, especially in rapidly evolving peri-urban watersheds. This research, therefore, integrated remote sensing techniques and repeated field survey of erosion pin plots to quantify bank erosion and sediment flux in the 80 km2 Nkisi River watershed (NRW), southeast Nigeria, over a three-year period. The impact of land use change on streambank erosion was evaluated by utilising remotely sensed Landsat datasets of 2003, 2010, 2016 and 2019. Geotechnical tests were used to characterise the lithologic properties of the banks, while the Bank Stability and Toe Erosion Model (BSTEM) was used to determine the stability of the banks under various hydrological conditions and mechanical properties of the riparian vegetation. Mean bank recession rates increased from 10.7 cm during the 2017–2018 monitoring period to 17.5 cm for the 2019–2020 monitoring period. The percentage of total watershed export ascribed to bank erosion in the three stream reaches varied from 6.6 to 44.9%. The high rates of bank erosion and accretion within the NRW were attributed to rapid changes in land use, which evolved from grassland and woodland to cropland, built-up and bare land. The BSTEM accurately predicted the high erosion rates of the streambanks and showed that riparian vegetation has a mechanical effect on bank stability. However, the mechanical effect diminishes as the depth to water table rises during high streamflow events.
