The Effects of Dam Construction on the Environment, A...
Literature Review Many developed and developing countries worldwide depend on hydroelectric dams as a major source of their electricity power. Due to increase in population size and economic related activities, the demand for more electricity continues to rise (International Energy Agency, 2006). To meet such demand, government and energy providers in many developing countries are likely to turn to hydroelectric dams as a promising source of renewable electric power (Ledec Quintero, 2003). Dam construction has its effects towards the surrounding areas. The environmental impacts may include the flooding of the natural habitats, loss of terrestrial wildlife, deterioration of water quality due to the reduced oxygenation and dilution of pollutants, spreading water-related diseases, drop in waterââ¬â¢s level including involuntary displacement just to name a few (Ledec Quintero, 2003). McDowell, too, argues that involuntary population displacement or transfers may lead to irreversible social and cultural impoverishment (McDowell, 1996). Forced population displacement may lead to eight forms of impoverishment: unemployment, homelessness, landlessness, marginalization, food insecurity, loss of access to common property, erosion of health status and social disarticulation (Cernea, 1990). In identifying the potential adverse environmental, social and economic impact and increased positive outcomes related to hydropower development appropriate initiatives are normally taken intoShow MoreRelatedWhy Is Beaver Activity Is A Public Nuisance Or Beneficial Ecological Restoration?1749 Words à |à 7 Pagespublic nuisance or beneficial ecological restoration has much to do with peopleââ¬â¢s understanding of beavers. The abundant geomorphic and ecologic literature on beaver processes seem to have been generally overlooked in the debate of public policy.

We found that natural and beaver-dammedRead MoreThe Socio-Economic Effects of Spring Grove Dam in the Midlands Area2369 Words à |à 10 Pagessocio-economic effects of Spring Grove Dam in the Midland s area [Source: www.springgrovedam.co.za] Table of Contents Page Introduction: Aims and Objectives 3 Location Aim Hypothesis Factors of Investigation Review of Literature 5 Data/Information Gathering and Presentation of Findings 7 Analysis, Interpretation and Discussion of Findings Conclusion and Evaluation Referencing INTRODUCTION Location and information about Spring Grove Dam: Spring GroveRead MoreThe Effects Of Water Related Climate Change Adaptation Interventions On The Local Communities Essay1285 Words à |à 6 PagesIn order to explore the impacts of water-related climate change adaptation interventions on the local communities, the research should clarify the main concepts and theoretical frames for the key concepts and related literature review on these concepts. a) Relevant literature i.
