Assessing environmental awareness activism to river decay and recurring pollution using parallel multiple mediator model
No full textThe decay of rivers coupled with its escalated pollution is a concern worldwide. The present study intends to assess the agony of the riverine people due to the contamination of the Churni River and the transformation of their grievance into environmental activism at individual and community levels for rejuvenating the river and for a secured livelihood. The study observed an enriched concentration of biological oxygen demand, nitrate, and phosphate and a reduced concentration of dissolved oxygen during 2011–2020 due to the release of untreated industrial wastewater, sewage from urban areas, and agricultural runoff into the river. A systematic investigation reveals pollution-induced socio-psychological trauma and community awareness leading to the active involvement of the people in the environmental awareness movement, which was mediated by self-efficacy, self-responsibility, self-identity, and community value. A parallel multiple mediator model was employed, which included 29 parameters for exploring the key-mediated factors for the environmental movement. The model-based results identified that self-responsibility and community-value for upper stretch villages and self-efficacy and community-value for the lower stretch villages are significant mediators of environmental activism. A canonical component analysis predicted socio-demographic factors (e.g. age, dependency ratio female-male ratio, etc.) as intrinsically linked to environmental activism. This study is significant because it reveals how pollution and river degradation affect riverine people. It also clarifies how local grievances turned into environmental activism as a result of the documented socio-psychological trauma and growing community awareness. This study would thus play a pivotal role in understanding the human-nature complex to better planning and river restoration.</p
Assessing the Community Capacity for Environmental Stewardship (in Langkawi Malaysia)
No full textThe structure of tourism has the potential to create numerous opportunities, beneficial effects and conservation incentives for island communities. However, its negative impacts can gradually destroy the resources upon which it depends. Hence, it is essential for the local community to take responsibility, address problems, act effectively and lead the roles to protect their living area while exploiting tourism industry. The main purpose of this study is to assess the level of community capacity for environmental stewardship from tourism negative impacts in Langkawi Island, Malaysia. This study employed a quantitative method. The outcomes provide the current level of community capacity for environmental stewardship as well as general characteristics of Langkawi local community. The results may give a better insight toward achieving systematic change in local communities regarding conserving and protecting natural environment from tourism environmental costs. It may also help to obtain further tourism development while minimizing negative environmental impacts

Soil erosion and sediment yield estimation in a tropical monsoon dominated river basin using GIS-based models
No full textThe increasing soil erosion (SE) and the associated problems for society, economy, and environment sparked a lot of interest in estimating and mapping SE at different basin scales. The estimation of SE exhibits that SE ranges from 10 to 50 t ha−1 yr−1, with a mean SE of 20 t ha−1 yr−1. The very steep slopes account for 54.21% of total soil loss. The SRB areas where soil loss rates are >10 t ha−1 yr−1 are considered the target areas which account for 27% of the study area and 96% of the soil loss). The high SY is concentrated only in the first-order basins located in a higher slope zone in the northern part of the river. Besides, basin morphometry (basin shape, relative relief) and anthropogenic activities (agricultural land) are retained in the PSLR model as significant factors contributing to SY in the entire river basin.</p
