The increase in tourism in the area along with all the improvements in infrastructure around the area will help develop the local economy and benefit all surrounding communities. The subject of dam construction has been a hotly debated issue especially since the 1960’s when the environmental impact of dam construction started to be considered and analyzed. To start with constructing a new dam is an incredibly expensive and complex undertaking, usually with total project costs running into the billions and taking numerous years to complete (Pottinger, 1996). When a dam is constructed in a river system the whole balance of the ecosystem upstream and downstream of the newly constructed dam will be negatively affected or even completely destroyed as a direct consequence of disrupting the natural seasonal flow of the river system. Prior to the construction of the dam, the river has a natural flow that responds to the seasonal changes and brings a constant flow of debris and sedimentation that helps bring food and nutrients for all the natural wildlife living in the river system. After a dam is constructed the flow of the water is artificially limited and c ontrolled so the flow is usually constant and very restricted and only increased to decrease water levels or increase power production and does not correlate natural seasonal fluctuations. Furthermore all the sedimentation and the necessary food and nutrients carried with it will now be deposited in the impoundment upstream of the dam, destroying the ecosystem and killing most of the natural wildlife downstream. The evaporation rate of the river system will be significantly higher because of the vastly greater surface area

Description of Christo and Jeanne Claude`s Installation The Gates - Essay Example It is all about altering the space and thus altering the eye. ‘The Gates’ have a rare quality that combines an open invitation with an exciting sense of mystery at every step into it. The saffron clothe hung at each gate just like a half-curtain had a function of masking the view ahead, for a few moments, when a person passes through it (Christo and Jeanne Claude â€Å"The Gates†). The gates masked the panoramic view at each step but also revealed a new vision also at every step (Christo and Jeanne Claude â€Å"The Gates†). The saffron wardrobe in which Christo and Claude had dressed up the classic elegance of the park provided a contrast beyond comparisons so as to make the onlooker feel as if he/she was entering a surreal world (Christo and Jeanne Claude â€Å"The Gates†). The monotony of visual experience caused by the repetition of the gates has a purpose to serve. It hides the contours of the park and gives out a monolithic experience where even when a visitor walks miles and miles, she would feel she had not moved at all. By repeating the space and expanding it, thus the artists had manipulated time as well, by instilling a feeling of eternity. The equal distance that is kept between the gates is yet another artistic technique to enrich the feeling of infinity. The very material presence of the textile is suggestive of the time-limited nature of this work of art. It is evident to the visitor to this work of art that it is not going to last forever just like a painting or a sculpture. Yet it has a unique value as a spectacle, a value that a painting or a sculpture cannot command. It is the time-constraint that imparted it a value as a spectacle. The installation also offered the onlookers, a side view, from the road, which was equal to an outside v iew. From this viewpoint, the gates transformed into a neat row of big women legs clad in saffron skirts (Christo and Jeanne Claude â€Å"The Gates†).
