The Impact

Rivers play a significant role in the human activities all over the world. Increasing demand of water for drinking & irrigation and hydroelectricity, numbers of impacts can be seen in the rivers environment. The present paper focuses on the impact of Supana Dam on the channel morphology of Alaknanda River in Srinagar valley Garhwal Himalaya. The field investigation approach has been adopted for the present study. The impact assessment has been carried out into three categories i.e. (i) Impact of dam on channel morphology, (ii) Impact of dam on human environment and (iii) Anthropogenic impact on channel Morphology. The results of the study show that after the construction of dam positive and negative impact have been assessed. Due to the blockage of water and sediment flow the entire riverine environment has been changed. Channel morphological features are well exposed for geomorphological study. Changing pattern of land and water relationship destroyed the previous ecosystem balance. Besides this, dam is supplying cheapest clean, efficient and reliable energy generated by hydroelectric power plant. Other impacts of dam are loss of fauna and flora, quality of drinking water supply and concentration of pollution in downstream. Out of these large numbers of sand and gravel extraction activities has been started on the exposed channel bed. Although some positive and negative impacts are observed by the construction of dams but several measures have been suggested to mitigate the adverse impacts of a hydropower project in the present study area.

Abstract Cypripedium calceolus is considered an endangered species in the territory of Poland. Population of this rare species, situated at Lake Kwiecko (Western Pomerania), was regularly monitored in the years 1986-2013. The studied population has been under the permanent influence of the nearby hydroelectric power plant for almost 45 years. The field observations showed that the power plant had no negative impact on the condition of Cypripedium calceolus population. An indication of its good condition was, among others, an increase in the size - from 150 to 350 specimens within the study period.

Abstract . Dynamic environment in coastal area, especially due to coastal erosion process, has negative impact on human environment. Sayung coastal area, located in Central Java-Indonesia, has experienced severe impact of coastal erosion. As the result of the coastal erosion, hundreds of settlement located in coastal area has been destructed. Moreover, fishponds as the land use dominated in the coastal area also has been severely destroyed. Besides the coastal erosion, increasing of inundated area due to sea level rise also threaten the local community. Although devastating impact suffering the coastal area, the people of Tambaksari, as the part of Sayung area, decided to live and adapt with the coastal erosion. This paper aims to identify the coastal erosion and understand adaptation strategies held by the local community related to reduce the impact of the coastal erosion. Based on this research, various adaptation strategies has been identified, namely (1) Planting mangrove alongside the shoreline, (2) elevating the ground level, (3) building staged house, (4) utilizing deep well for freshwater supply, (5), maintaining social interaction with mainland community, (6) Collecting fish from the mangrove as the food, and (7) changing work into the tourism sector.

The Impact

Increasing demand for gluten-free foods is driving restaurants to add gluten-free menu items. However, it remains unclear how gluten-free labels affect food consumption and overall evaluations of a dining experience. We conducted two studies to fill this gap. Results from Study 1 suggest that unrestrained eaters (i.e., people with low levels of dietary restraint) expect to decrease their food consumption when a menu item bears a gluten-free cue, whereas restrained eaters (i.e., people with high levels of dietary restraint) do not show such an effect. This negative impact of a gluten-free cue on consumption among unrestrained eaters is mediated by expected taste. Results from Study 2 show that when a gluten-free purchase is incentivized with immediate incentives (i.e., price discounts), an increase in dietary restraint leads to a heightened salience of a health goal. Such an effect is attenuated with delayed incentives (i.e., redeemable points). The health goal salience mediates the impact of dietary restraint on anticipated satisfaction with a gluten-free dining experience incentivized with immediate rewards. This research contributes to the hospitality literature and the broader literature on food consumption. Moreover, our findings suggest that managers need to focus on clearly communicating the appealing taste of gluten-free foods and aim at activating a health goal among unrestrained eaters.

The Impact

Biodiversity loss is accelerating rapidly in response to increasing human influence on the Earth’s natural ecosystems. One way to overcome this problem is by focusing on places of human interest and monitoring the changes and impacts on the biodiversity. This study was conducted at six sites within the influence area of the Santo Antônio Hydroelectric Power Plant in the margins of the Madeira River in Rondônia State. The sites cover a latitudinal gradient of approximately 100 km in the Brazilian Amazon Basin. The sampling design included six sampling modules with six plots (transects) each, totaling 30 sampling plots. The transects were distributed with 0 km, 0.5 km, 1 km, 2 km, 3 km and 4 km, measured perpendicularly from the river margin towards the interior of the forest. For sampling the ground-dwelling ants, the study used the ALL (ants of the leaf litter) protocol, which is standardized globally in the inventories of ant fauna. For the purpose of impact indicators, the first two campaigns (September 2011 to November 2011) were carried out in the pre-filling period, while campaigns 3 to 10 (February 2012 to November 2014) were carried out during and after the filling of the hydroelectric reservoir. A total of 253 events with a total of 9,165 occurrences were accounted during the monitoring. The ants were distributed in 10 subfamilies, 68 genera and 324 species/morphospecies. The impact on ant biodiversity during the periods before and after filling was measured by ecological indicators and by the presence and absence of some species/morphospecies. This is the first study, as far as we know, including taxonomic and ecological treatment to monitor the impact of a hydroelectric power plant on ant fauna. Until recently, most studies conducted on hydroelectric plants, located in the Amazon Basin, were carried out after the implementation of dams in order to assess their impacts on the environment and biodiversity (Benchimol and Peres 2015, Latrubesse et al. 2017, Sá-Oliveira et al. 2015). Recent studies on dam impacts have begun to be conducted prior to dam implementation (e.g. Bobrowiec and Tavares 2017, Fraga et al. 2014, Moser et al. 2014), thus providing a better overview of the impact and a better assessment of its magnitude.

Declining water resources and increasing demand of water for agricultural, industrial, and domestic sector and potential climate change has posed a major challenge to maintain water sustainability of a nation. There is a need to adopt long-term perspective for assessment and policy design for sustainability of primary resources like water. It is also argued that virtual water trade has raised issues of water sustainability as even small but continuous net virtual water trade may influence the water sustainability through irreversible losses. With the constraints for water sustainability, virtual water trade has received much attention in the recent years. While the impact of virtual water trade on water sustainability of virtual water exporter country is less explored and assessed. India is a major water exporting country resulted tremendous pressure on water resources that has serious threat to food security and the negative impact on development of economy and other sectors.

The Impact

The continuous interference of human activities in continental aquatic systems results in direct and indirect impacts, with consequences for water quality, aquatic biota and the dynamics of water resources. In this context, the Tucuruí Hydroelectric Power Plant (HPP) acquired relatively importance, as it was the first large dam carried out in the Amazon, in the 1980s, presenting important technical/economic results to justify the environmental costs associated with the project. The objective of this study was to apply a new methodology to represent through maps georeferencing biological information and evaluate the impact of the dam on the following fish species, which have different physiologies and taxonomies, in addition to not having much biological information about the species: Botinho (Hassar wilderi, Doradidae), Mandubé (Ageneiosus ucayalensis, Auchenipteridae), Sardinha Papuda (Triportheus trifurcatus, Characidae) and Uéua Cachorrinho (Acestrorhynchus falcirostris, Acestrorhynchidae). The condition factor related to the relationship between the individual's weight and body length, which derives from an expansion of the cubic law of living beings, being very important in ecological studies, even though they depend on simple to the most complex scientific methods, to estimate this bodily condition. Furthermore, this biological parameter influenced by environmental conditions and characteristics, due to food availability and ecological relationships in the environment. This information can support an adequate fisheries management, as there is an integration of fisheries biology and the characteristics of the environment in which they live. Thus, the methodology applied in this study was successful in its application proposal.

Debris Floods

Abstract Winongo River originates from small rivers on the slopes of Mount Merapi. This creates potential debris floods that will carry material such as sand and gravel, which can cause erosion and sedimentation in rivers. Riverbed erosion is the process of transporting materials on the riverbed that causing the elevation on the riverbed to fall. If the riverbed elevation decreases, it will cause the retaining wall building to become unstable and collaps. If this happens, it will have a negative impact on the people who live along the riverbanks. The impact of erosion and erosion analysis at the bottom of Winongo River is carried out using HEC-RAS 5.0.7. There are 200 cross-sections that had been analyzed. The analysis reveals that the locations have the potential of erosion on the riverbed and the damage that can occur in the riverbank. From the results of the analysis that have been carried out using the 2-year return period (Q2), there are erosion in 9 cross-sections on Winongo River which is located in Bambanglipuro District and Jl. Parangtritis. The depth of erosion that occurs reaches 0.96 m in the cross-section WN 173. The erosion causes damage to the retaining wall, such as cracks, flattening, and collaps.
