Faustus and Conflict Essay Example for Free

Faustus and Conflict Essay Christopher Marlowes play Doctor Faustus presents a story that is filled with various forms of significant philosophical conflict. While, on the surface, the play is intended to focus on the form of Faustus fortunes, the scope of the play includes commentary on several other important themes (Prologue.8). Marlowe uses Faustuss position to demonstrate a sharp contrast between the values of the medieval time period with the developing values associated with the Renaissance movement. Faustuss story shows a direct conflict between the traditional and the modern in its form, its ideology, and its view of religion. Since Marlow maintains an ongoing struggle between these various elements throughout the play, a struggle also exists between the tragic and comedic elements of the story. Marlowes ambiguity toward the primary direction of the play creates a situation in which the ultimate purpose of the plays comedic scenes remains uncertain even after Faustuss final moments. The content of Faustuss story superficially focuses on Faustuss struggle to maintain control over the destiny of his own soul. Faustuss desire to become a mighty god leads him to make a deal with Lucifer, in which he exchanges his soul for twenty four years of demonic power (1.62). Throughout the play Faustus struggles with repentance and disbelief, and he is eventually condemned to Hell for his actions. Symbolically, Faustuss story is more appropriately a representation of the struggle, evident during Marlowes time period, between the traditional ideas of the medieval period and the modern ideas of the Renaissance. This conflict is evident within the first few lines of the play. Marlowe begins the play by having Faustus announce that he has given up on the traditional schools of thought, such as the study of religion, law, and medicine. Instead, he plans to study that damned art of necromancy or black magic (2.29). While traditional medieval thought encouraged the unquestioning acceptance of ancient philosophy, Renaissance thought encouraged experimentation and a rethinking of previously accepted beliefs. While Faustuss actions may show his support of these Renaissance beliefs, his ultimate demise suggests that Renaissance thought may also be imperfect because it does not include a belief in God. This dualism between modern and traditional thought is also evident in the structure of the play. Marlowe employs elements that would be common in most traditional plays, such as the use of a chorus. He also uses mythical comparisons, depicting Faustus as another Icarus, a man who will eventually mount above his reach (Prologue.21). Faustus is also depicted as a tragically flawed character. Faustus is portrayed by the Chorus as being swollen with cunning (Prologue.20). Like Achilles, Hercules, or other traditional Greek heroes, Faustus has a character flaw that will mostly likely lead to his demise, but the eternal damnation of Faustus, to the Elizabethan audience, would be the equivalent of damning great Greek heroes, and thus creates artificial traditional expectations of the play. Simultaneously, Marlowe also ignores many of the important characteristics of traditional tragedies. While most tragedies depict historically important characters, Faustuss story is a tale of an ordinary man, not of the courts of kings or the pomp of proud audacious deeds (Prologue.4-5). By focusing on the common man and also by writing in blank verse, a style that was uncommon during this period, Marlowe breaks away from the traditional expectations of a tragic play. Faustuss view of religion also constantly vacillates between a traditional acceptance of Christianity and a modern rejection of it. When Faustus initially reads that [t]he reward of sin is death, and that [i]f we say we that we have no sin, / We deceive ourselves, and there is no truth in us he suggests that Christianity is a futile endeavor and decides that What will be, shall be! Divinity, adieu! (1.40-43, 48). He mistakenly characterizes Christianity as being based on punishment rather than on forgiveness, a mistake that he repeats throughout the play. Later, he believes his heart has become so hardened that he cannot repent! (5.196). While he initially suggests that Hell is nothing but a fable, Faustuss religious convictions continue to grow. Upon seeing Lucifer and Mephistopheles, he cries out, O Faustus, they are come to fetch thy soul! and even murmurs Consummatum est, meaning it is finished, which were Christs dying words on the cross, after signing his deal with Lucifer (5.264, 74). In this manner, Marlowe remains ambiguous throughout most of the play as to his position on the various conflicts he has depicted. For the audience, Faustus position as a modern man and Marlowes portrayal of religion remain in doubt. For this reason, the comedic scenes also remain ambiguous throughout the play. The audience remains uncomfortably unsure as to whether the comedy is intended to garner support for Faustus as the ultimate hero of the story or to mock Faustus by foreshadowing his own demise. The conclusion of the play demonstrates that the comedy depicted in the play, in addition to its theatrical purpose of providing a comedic interlude, provides a critical depiction of Faustuss fall from grace. One of the first comedic scenes in the play occurs when Faustus asks the demon Mephistopheles to reappear in the habit of a friar since [t]hat holy shape becomes a devil best (3.26). While the depiction of a devil in the garb of a Catholic friar would have undoubtedly been hysterical to Marlowes staunchly Protestant audience, the scene also carries significant meaning. By having Mephistopheles disguise his true figure, Faustus, despite his fearless speech, seems unable to stomach the true nature of Hell. Even when Mephistopheles seems to warn Faustus that his own pride and insolence have forever barred him from the face of heaven and that he is now tormented with ten thousand hells, Faust clings to his own diluted version of Hell (3.67-68, 79). He delusionally envisions Hell as a continuation of an earthly existence, and criticizes Mephistopheles for his lack of manly fortitude (3.85). The comedy within the play is continued by the antics of the characters Wagner, Robin, Rafe, and the Clown. Most of these comedic actions seem to foreshadow Faustuss own downfall. The first depiction of Wagner and the Clown mirrors Faustus signing his soul over to Lucifer. During this scene, Wagner convinces the Clown to become his servant for seven years, and the Clown jokes about how he would sell his soul for a shoulder of well-seasoned mutton. While represented in a comedic fashion, this scene foreshadowing the triviality of the power Faustus has obtained in exchange for his soul. As suggested by Mephistopheless unwillingness to discuss things that are against our kingdom, Faustus soon discovers that there are severe limitations placed upon the power wielded by Lucifer and his minions (5.247). In another comedic scene involving these characters, Robin, the stable hand, and Rafe steal a cup from a tavern and are pursued by the tavern wine-maker. Robin summons Mephistopheles to frighten the vintner, and is chastised by the demon for being summoned for a practical joke. Mephistopheles threatens to turn the two men into a dog and an ape. While Mephistopheles is obviously angered by the triviality of Robins request, his anger also reflects his own suggestion that Faustus abandon his frivolous demands (3.81). This scene foreshadows how Faustus will eventually abandon his own lofty goals and will also use his power primarily to play practical jokes. Much of the comedy in the play is related to the digression of Faustuss goals and the ways in which he employs his power. Faustus begins the play with many lofty goals. With his powers, Faustus plans to have spirits bring him jewels from around the world, teach him vast secrets of the universe, and make him king of Germany. He planed to change the course of the Rhine River and remake the entire map of Europe. Initially, Faustus appears to be on the path toward reaching these goals. Wagner tells how Faustus has ridden through the cosmos on the back of a dragon learning the secrets of astronomy from Mephistopheles. But Faustus quickly losses momentum, and, upon reaching Rome, decides to use his power to play practical jokes on the Pope. While this idea would, once again, be extremely funny to Marlowes Protestant audience, it represents the beginning of Faustuss digression. As time progresses, Faustuss audiences also decrease in their level of importance. Following his time with the Pope, one of the most influential figures during this time period, Faustus meets the German Emperor Charles V, who is also an important figure but not as important as the Pope. During this meeting, Faustus, unable to fulfill the requests made by Charles due to more limitations on his powers, embarrasses a disrespectful knight in the Kings court by placing antlers on his head. This digression continues as Faustus final audience is with a simple nobleman and his wife. Faustuss display of power consists of fetching out of season grapes for the noblemans wife. The comedy during these scenes primarily includes a practical joke Faustus plays on a horse-courser. Like Robin and Rafes practical joke, Faustus now uses his power to play jokes on people his has already angered. Like many other aspects of the play, the comedy depicted by Faustuss gradual demise also remains ambiguous. For many, this demise can be seen as a failure in Renaissance thought. Faustuss search for power and knowledge has left him disconnected from God, the ultimate source of both. By not including God or morality in his search for truth, Faustus has become corrupted by the influences of power and no longer retains his somewhat nobler purposes. But Faustus also simultaneously fails in his attempts to incorporate a more traditional view of religion into his life. He recalls that Christ did call the thief upon the cross, believing that he too will be brought into paradise. Faustus, particularly during his last hours on Earth, seems to exhaust every possibility of incorporating religion into his life. He offers to make deals with God, begs for mercy if not redemption, and even turns to Helen of Troy, a representation of feminine virtue or Mother Mary, for reprieve. Faustuss condemnation demonstrates how Faustus has been simultaneously failed both by traditional religion and by the beliefs held by modern Renaissance thinkers. In conclusion, the comedy within this play serves a variety of purposes. Like many of the other elements in the play, the comic and tragic elements seem to struggle with one another throughout the play. This struggle is also seen in Faustuss struggle between Renaissance thought and form and a more traditional view of life and religion. When coupled with these various forms of conflict, the comedic scenes within Doctor Faustus cause the play to constantly waver between tragedy and comedy, leaving the audience without any knowledge of how the play will ultimately end or of the true meaning of the play. Most of the comedy seems to mock Faustuss decision to embrace a modern philosophy toward life, but, when religion ultimately fails him as well, Faustus seems to be a completely hopeless representation of man. The plays comedic scenes are another method, employed by Marlowe, to create confusion and veil the true significance of the play.

Case Study Of The Akosombo Hydroelectric Dam Environmental Sciences Essay

Case Study Of The Akosombo Hydroelectric Dam Environmental Sciences Essay The construction of Akosombo dam on the Volta river basin in Ghana created Volta Lake the largest man-made lake by surface area in the World. The purpose of this study was to examine the benefit and consequences of the dam on social, environmental and health issues. Critical analyses of primary literature over five decades were reviewed and some management solutions were outlined. The Akosombo hydroelectric project (HEP) contributed to accelerating of Ghanas economic development through industrial and mining sectors as well as for providing cheap electricity for domestic and commercial consumer. Fishing, transportation and tourism were positive benefit from the dam. However, negative impacts like the resettlement of 80 000 people, increase in health problem like the high rate of HIV, socio economic deprivation and injustice and destruction of the ecosystem. The greatest challenge facing Akosombo is management and lack of research on the aquatic systems at the basin. Key recommendatio n includes environmental compensatory approach and research into environmental flows of the Volta River. Ultimately, it is important for future HEP in Ghana be precede and adheres to EIA reports and involves stakeholders from planning to post construction stage to maximize overall development benefits, encompassing economic, social, and environmental impacts INTRODUCTION Hydro-electric power is an important source of energy for many countries especially in the tropical countries without advance technological development. In 2007, 3.2 % of global energy consumption and 20% of electricity generated came from hydropower (IEA, 2010). In many countries especially in Central America and Sub-Sahara Africa over half of all electricity generated comes from HEP (Anderson et al. 2006a and Gyau-Boakye 2001). The major advantages of HEP which makes it a preferred renewable energy sources are cost, zero air pollution, longer life span of plant, the low level of expertise for running and maintenance of HEP and lack of post production storage problems. Perhaps the biggest advantage hydropower enjoys over other sources is the fact that the cost per unit of electricity generated from hydro is cheaper than any other source. Globally, the trend of newly constructed hydropower has shifted from the temperate region to the tropical regions in the last two decades (Pringle et al., 2000). Dams construction is expected to double in developing countries due to expanding human populations, increasing rural electrification, and growing demands for electricity in the developing countries (Anderson et al. 2006a). Although the bulk of hydrodams constructed recently have been in the developing countries with China leading the number of newly constructed dams, the recent announcement of a major dam to be constructed in Alaska indicate the pull of hydro even as undaming of major rivers is taking place. It is projected that hydropower production would grow by nearly 60% in 2050 if the current rate of construction is maintained.(dams.org, 2010) Despite the numerous advantages, hydro-electric power (HEP) causes more ecological damage than all the rest of the renewable energy put together. The damage done to the natural flow system of rivers and associated impact on the ecosystem are documented in many studies (Anderson et al., 2006b; Pingle et al., 2000; Craig, 2000). They include natural flow alteration of a river, destruction of hydrologic connectivity, impeding the migration of fish and other aquatic biota effects. Asides the ecological impact, there is also the issue of social impact on the communities which includes changes in the landscape leading to flooding, displacement of local residents, increase in health risk factors as a result of the dam and reported deaths from dam failures. The Volta River Basin is located in West Africa and covers an estimated area of 400,000 km2 and is spread over six West African riparian countries (Burkina Faso, Ghana, Togo, Benin, Cote dIvoire and Mali). There are a number of dams located within the Basin of which three large ones, Akosombo, Bagre and Kompienga, are solely for hydropower purposes. The Akosombo dam, which was constructed from 1962 to 1966 in Ghana, is by far the most significant structure built in the basin since the resulting lake is the one of the largest man-made lake in the world (Barry et al., 2005) and covers 4% of the surface area in Ghana however, the actual reservoir only has a surface area of about 8500 km2, an average depth of about 18.8m and a shoreline of about 5,500 km (Barry et al., 2005). The formation of the lake led to the generation of economic activities like transportation, fishing and tourism along the lake (Kumi, 1973). Although the primary purpose of the Akosombo hydrodam was to supply electricity for Volta Aluminum Smelting Company (VALCO) located 80km from the dam at Tema, Ghana, it contributed to accelerating of Ghanas economic development through industrial and mining sectors after its construction as well as for domestic and commercial consumers. Currently the dam supplies around 85% of Ghanas electricity need providing an average annual output of 6100 GWh. Despite the benefit of the dam to the country the long term environmental and social cost has been staggering. This paper seeks to review the impact of hydrodams in the Volta Basin with primary focus on the Akosombo dam. The aim of this study explores the biodiversity challenges facing the basin as a result of the HEP construction and review the impact on the social and the ecological aspects of the basin. Primary literature would be used to assess how the dam has positively or negatively affected the socio-environment aspects [the ecosystem (physical components, the biological community and water quality), social, health and economic impacts] of the basin. The study would focus specifically on the Akosombo but inference would be drawn from other dams across the basin in the analysis. Based on the study, outlined recommendations and solutions would be made for existing and future dams that might be constructed on the Volta River THE AKOSOMBO HYDROELECTRIC PROJECT The Volta Basin lies within latitudes 5 °.30 N and 14 °.30 N and longitudes 2 °.00 E and 5 °.30W. It is located in West Africa with six riparian countries (Ghana (42%) and Burkina Faso (43%) and the remaining 15% in Mali, Cà ´te dIvoire, Togo, and Benin) with Ghana occupying the downstream of the basin (figure 1). The building of the Akosombo dam follows almost a period of two decades of planning which began in 1947 when the first feasibility studies were conducted on the potential for volta river as a hydropower source. The bulk of the funding for the project estimated $ 260 million. was secured by Kaiser Aluminum from a US bank under persuasion from President Eisenhower in face saving from public relation disaster (GW 2010) The HEP was directly linked to efforts made to develop the huge Ghanas integrated bauxite to aluminium industry. The actual construction of the dam took place within1962-1972 under the management of the Volta River Authority (VRA) who were legally manda ted by the Act 46 to be caretakers of all Volta River related activities in Ghana. The Volta River Authority (VRA), a government owned utility, is largely responsible for electricity generation and transmission in Ghana. There were three phases of the project, phase one was the installation of 588MW unit of electricity which was completed in 1966m. The second phase involved an addition of 304MW electricity which resulted in total of 912 MW at the Akosombo dam. The last phase of the project was the setting up of a smaller HEP dam, 21km downstream, at Kpong. In terms of dam classification, the Akosombo dam is often classified as large dam whiles that of Kpong is classified as small hydro dam. Today a total of 1072MW of electricity is generated by the Akosombo HEP (VRA, 2010). The first phase of the projected resulted in the creation of Lake Volta (man-made lake) which is the most significant water body in the Volta basin. The lake covers an estimated area of 8500 km2, a length of 400 km and a shoreline of 5500km (Gyau-Boakye 2001) but rather shallow with a maximum depth of 113m. It receives flows from three rivers Oti, Black Volta and White Volta and discharges into the lower Volta river and then the Atlantic Ocean. The maximum capacity is around 150,000 million m3 of water at its peak of 278 feet. (VRA 2010) The main objective of HEP production is to make VALCO energy sufficient so that its activity which is mainly aluminum smelting would be proceed without interruption. The other objectives were to supply electricity for both domestic and industrial use and also export to the basin sharing countries (Benin and Togo). The Volta River Authority (VRA) a government owned entity was established in 1961 under the Volta River Development Act 46 and tasked with the management, maintenance and sustainability of the Volta River and HEP production. The act also gave the VRA the responsibility to generate and transmit electricity as well as safe-guarding the health and socio-economic well being of the inhabitants of the communities alongside the lake. Prior to the flooding stage of the dam, the VRA had to relocate people inhabiting traditional, administrative and all other lands that were to be inundated. BENEFITS OF HYDROPOWER FOR GHANA The construction of the Akosombo HEP and the creation of the Volta Lake have provided several positive benefits. The Akosombo HEP provides over 85% of all electricity generated in Ghana (Winston et al., 2006). The electricity generated has encouraged economic and industrial development in Ghana. Prior to the construction of the Akosombo HEP, Ghanas total power usage was around 70MW and this was isolated with individual standalone power supply system which was owned by industrial establishment such as the mines, factories and other major institutions (Aryeetey, 2005).and assess to electricity was restricted to less than 3% of the population. Today an estimated 60% of the population has access to electricity including 20% of the rural communities (ECG, 2008). Over two-thirds of all the electricity generated goes to industries and commercial entities; this led to rapid expansion and immigration of industries into Ghana from other West African countries to take advantage of the cheap ele ctricity available from the HEP. As a result Ghanas economy is twice the average of the West African sub region (IMF, 2010). In years of drought where HEP energy generation has been poor, unemployment rate rises exponential attesting to a positive externality of the Akosombo dam. The creation of the Volta Lake led to increase in fishing stock thereby making fishing a lucrative business to the inhabitants along the lake. Similarly, farming activities also intensified along the 5500 km shoreline especially locations downstream of the lake as a result of water availability for the purposes of irrigation and more importantly alluvium sediment deposition which is very fertile and has high content of organic matter. Also the navigation on the Volta river has changed significantly serving as a mean for transportation for goods and people across the lake where road are poor or unavailable. To the inhabitants creation of the transportation route on the lake which stretches from south to north has been one of the important benefits to the communities. The direct tourism impact resulting from the lake includes opening up part of hitherto inaccessible attractions (because of the location of the dam, the sight of the lake the environment, etc.) to both local and internati onal travelers. The lake and its designated national park Digya located at the west shore of Lake Volta and the resort island have provided a popular holiday destination. CONSEQUENCES OF AKOSOMBO HYDROPOWER Like all hydropower dams constructed the Akosombo HEP have had a social, environmental and physical impact on the communities upstream, downstream, the project site and even beyond the extent of the dam. On the social front the most prominent problem that is directly linked to the HEP is the displacement of 80,000 people across 700 villages in low lying areas and resettle them into 52 new villages (Kalitsi,2000). The lost of the original communities resulted in many socio-physiological problems in the communities including high death rate among the aged, breakdown of cultural practices and breakdown of traditional law and order (Gyau-Boakye, 2001). The higher death rate is attributed to the grieving for the lost land syndrome (Okoh, 1986). The Volta lake creation leads to a loss of 3.6% of the total land surface of Ghana including forest land to the reservoir.(Fobil et al. 2001) The lost land lead to decline in the primary economic activities of crop and livestock farming for most of the communities both downstream and upstream of the dam. As a result of less arable land to farm the men switch to fishing while most of the women (a taboo for women to fish in Ghana) were involved in pr ostitution as a profession to satisfy the male workers whom were building the dam. (Suave et al. 2002) In terms of the standards of living the inhabitant of the project site Akosombo enjoy the best living condition not only in the entire Volta basin but better than the major urban centers in Ghana. Surprisingly, the upstream communities and downstream communities are among the poorest in the country lacking access to basic necessities like hospital, roads, proper sanitation and water facilities. Perhaps the most ironic social injustice to the communities upstream and downstream is that it took three decades to be connected to the national electricity grids. The HEP have increased the health related issues among the communities living around lake except in the town of Akosombo (Zakhary, 1997). Sam (1993), in his survey concluded increases in diseases such as schistosomiasis (bilharzia), malaria, onchocerciasis are directly due to Akosombo HEP. This is dues to the presence of aquatic weeds and increase in the population of water-born vectors like mosquitoes, black fly and snails.(Gyau-Boakye, 2001) Specifically, Urinary schistosomiasis (Bilharzia) has seen the increase of the incidence from 2% to 32% at Mepe,( downstream) and 0.5% to 27.4% at Adawso/ Okradjei, (upstream) along the lake (Zakhary,1997). Malaria has increased by an average of 10% both upstream and downstream since the construction of the dam. The fly, Simulium damnosum which cause Onchocerciasis (river blindness) also increased downstream in Kpong between 1970 to 1980 due to the new breading grounds created by the Akosombo dam, however the fly was not found again after compl etion of the smaller dam in Kpong in 1982 (Gyau-Boakye, 2001). As stated earlier The period between after the construction of the dam (1970-1980) coincide with the worst economic period in Ghana and the associated political uncertainty forcing the migration of the young women whom were inducted into prostitution during the dam construction to the various neighboring countries. Sauve ´ et al 2002 concluded that the high HIV prevalence rate (14.1% compare to 3% for the country) in Manya Krobo and Yilo Krobo districts located west and south of the Akosombo dam to a greater extent, a consequence of construction of the Akosombo dam in the 1960s prompted economically driven migration, specially to Cà ´te dIvoire, where many migrants became infected with HIV. This is surprising and rather peculiar to find a prevalence of HIV in semi-urban area that is much higher than those found in the countrys major cities. (Sauve ´ et al 2002). In terms of the physical geomorphology, the dam have created physical environmental problem. The most obvious is the increase in seismic activities around the dam since the construction of the lake. 4 major earthquakes of magnitude 5 or higher have been recorded in the area. Since there is no geological fault zone present in the lake, it is believe the earthquakes are due to the overloading of the geological bedrock underlying the lake with which is triggering the active Akwapim fault (Gyau-Boakye, 2001). Kumi (1973) concluded that the earthquakes might be due to readjustment associated with the lake in-filling. Another physical observation is that, sediments load have decrease by about 60mg/l downstream of the dam as a result of the impoundment (Barry, 2005). The lack of sediment has lead to the erosion of the coastline in the neighboring Togo and Benin at a rate of 10-15m/y (Gyau-Boakye, 2001). Another evidence of change is that the morphology of the delta have shifted 12 km eastwa rd from the original lower Volta entre point to the sea leading to coastal erosion at Ada.(Arp and Baumgaertel, 2005). In accordance with the behavior of tropical dam microclimate the temperature and rainfall in the south eastern part of Ghana is higher than the average in other parts of the basin and this is squarely attributed to the Akosombo HEP (Kumi, 1973, Rosenberg et al., 1990 .Opoku-Ankomah and Amisah 1998). The Akosombo HEP impact on the ecosystem unlike social and health issues have not been fully investigated and well. Fish and other aquatic biota are very sensitive to the hydropower operation due to the ability of the dam to alter and or blocking the migration resulting in genetic disconnect between species population (Baxter, 1977 and Pringle et al., 2000). The first compressive study sixteen (16) months after the construction of the dam by Petr (1967) showed that relative abundance of fish in the Lake were compared with those obtained from fish landings on the Black Volta and from the Niger river survey (Petr 1967). However the study did indicate an increase in plankton feeders, shell fish, Tilapia and a decrease Mormydiad and Alestes along the north-south axis of the river (Petr 1967). In 2000, about 87,500 metric tons of fish catch were recorded from the lake representing 98 % of the inland fresh water fish in Ghana (Braimah, 2001).Current fish estimated yield are 42-52 kg/ha/yea r based on catch statistics with Tilapia dominating the catch. However, the current trend of removal of standing timber in the forest which became part of the lake, in conjunction with overfishing, has negatively impacted the fish stocks especially in shell fish. Recent studies involving 165 fish sample covering 9 species in both the Akosombo and Kpong dam with Lake Bosomtwe (a pristine lake in Ghana) for mercury concentration showed levels below World Health Organization limit of 0.5 ÃŽÂ ¼g gà ¢Ã‹â€ Ã¢â‚¬â„¢1.suggesting no mercury in the HEP lakes mercury (Agorku et.al. 2009). Unlike newer dams constructed with EIA both the Akosombo and the Kpong dams do not have any fish ladders available for fish migration. In terms of the damage done to the ecosystem are unique and site-specific but generally the impacts invariably affect biota and biodiversity (Anderson 2006a). The Akosombo HEP is ranked in the top ten in terms of both social and environmental damage index (dams.2010). Flooding in the downstream communities is an annual event. The Afraim plain is a low lying rich farm land area suffers annually from the flow of the spillway river. A river flow is highly circumvented leading break in river connectivity. Although not unique to Akosombo, studies have shown that the large-scale impoundment may eliminate unique wildlife habitats and affect populations of endangered species. The Dibgya National Park close to the lake is a wildlife refuge site and it would be interesting to know how the lakes have affected wildlife in the park. Contrary to popular belief that HEP are emission free, scientific fact indicates that large dam projects and their reservoirs produces very significant greenhouse gas es (carbon dioxide, methane and nitrous oxide ) from the rotting of organic matter. The advocacy group International Rivers (formerly known as International Rivers Network concluded from their study Figure 2 that tropical dams in some case might be dirtier then fossil fuel in terms of GHG emission (IR, 2008) .Takeuchi (1997) concluded from his global survey of dams that the damage done to the ecosystem and electricity generated from Akosombo is very disproportionate. These impacts include loss of the actual wetlands as they are modified to suit particular irrigation practices and associated losses in biodiversity. (Takeuchi (1997) CRITICAL ASSESSMENT OF THE AKOSOMBO DAM50 YEARS LATER The Akosombo dam in 50 year of operation has been the cornerstone of Ghanas economic and industrial development. Likewise the HEP has cause and continues to remind us daily of the socio-environmental negative impact of living with dam. The original goal of the project in addition to the generation of electric power for industry urban and rural household was to provide opportunities for large-scale irrigation, modernization of agriculture, promotion of factories and industries, and the establishment of tourist facilities. Fifty (50) years later, it appears that the need at the time for the country to have a cheap source of electricity did have overriding priority over other considerations (Arp and Baumgaertel, 2005). The generation of electricity as stated earlier lead to the positive economic and industrial development along the eastern coast of Ghana. Analysis of the project goal and the implementation of the original blue print indicated that the VRA woefully mismanage the dams activities starting from the original resettlement scheme to their inability to meet the electricity need of the country. The resettlement of the communities and the compensation promised to the inhabitants were not fully paid, farming lan ds were insufficient for the villages while a lot of communities downstream whom were not accounted for were ultimately affected by the dam. According to the available data (ECG 2010) and personal observation the VRA after 50 years of operation have failed to meet its goal of providing electricity to the citizenry especially the social injustice that the majority of the affected people by the project were not connected to the national grid until recently .This undoubtedly showed that the authorities neglected the majority of the people affected by the dam to the benefited of the urban dwellers (Girmay, 2002). To their credit VRA undertook some activities towards the fulfillment of non-generation goals like the creation of the Akosombo Textiles Company, Kpong Farms Limited, the Akosombo Hotel Limited and Volta Lake Transport Company Limited (VLTC) to boast jobs and economic activity within the region. The downside to these projects is that inhabitants did not have the specialized ski lls and education levels required to take advantage of working in textiles industries or operating advanced machinery in the 1960s. The VRA irrigation and modernization of agriculture programs collapsed after at the implementation stage. Such program would have been more beneficial to the communities living along the dam since prior to the construction of the dam the majority of the people were into farming. The Akosombo dam and many others constructed in the developing countries before the 1972 Stockholm Conference on the Human Environment were without any environmental impact assessment (EIA) plan. In 1974, Ghana was the first country in Africa to establish an environmental governing body to deal with all environmental issues under one agency known as Environmental Protection Council (Appiah-Opoku, 2001). Ironically, the Kpong dam whose construction began in 1976 did not have EIA in place. In order to combat some of the negative environmental impacts of the project the VRA introduce numerous cut and fix approaches. These programs include afforestation program along the banks of the lakes, weed controlling measures to control bilharzia., dredging activities at Volta estuary and the creation of Resettlement Trust Fund for remediation some of the socio-economic impact mitigation (Girmay, 2002, Fobil et.al. 2003,). The success of these programs is difficult to measure since most of them we re subjective in nature. The VRA did have some environmental management programs and policies but they suffered from implementation and enforcement (Girmay, 2002). The question often asked in the view of the social and environmental damage done by the HEP is if this cost is justifiable. To address these issue in the context of Akosombo HEP present a dilemma. Ghana until recently discovery of oil along it shore did not have any fossil fuel or expertise in nuclear energy to produce electricity from these sources. Hence, the HEP project was the lifeline in meeting part of its energy demand. As stated earlier studies have shown that the amount of greenhouse gasses produces by hydropower is lower than the corresponding fossil electricity (Anderson 2006a). Although critics point to the fact that Ghanas overreliance on HEP have hamper the development of alternative renewable energy sources which have affected the country in times of drought. The supply of cheap electricity to neighboring countries like Togo and Benin mitigate their coastline erosion by the project. Ultimately, the amount of electricity produced from the Akosombo/Kpong HEP and the social and environmental damage to the basin is not acceptable. The major destruction of the ecosystem habitats and the negative health and social impact on the upstream/downstream communities is much bigger than comparable dams elsewhere. For example Japan produces 2300MW of electricity from HEP and the damage is a tenth of what occurs in Akosombo (Takeuchi, 1997). Although the HEP have been helpful to the country economically, with proper management and sustainable planning; the level of success would have been higher and the environmental impact greatly reduced. With benefit of time the original proposal should have been implemented and enforced effectively. This would have reversed the trend today which has led to the communities upstream and downstream been among the poorest in the country. RECOMMENDATIONS The positive impacts and the negative effects of the Akosombo have been highlighted in this paper. In view of the negative socio-environmental factors like downstream flooding, resettlement of communities, ecosystem destruction among others it is important strategies are put in place to mitigates these effects and protects the ecosystem from current and future HEP. One way of mitigating the environmental and social cost is through environmental compensatory project approach or offsets. For example, the recent plan of the Brazilian government to build a third world largest dam requires the company who wins for the bid to pay an excess of $800 million to offset environmental damage and relocation. Also in India there is a legal requirement that forests flooded by reservoirs must be replanted elsewhere. Introducing such concepts in the planning stages of the dam would really help ensure that significant and unavoidable adverse environmental impacts are counterbalanced by a positive environmental gain, with an inspirational goal of achieving a net environmental benefit. This approach must be fused with properly developed policies for resettlement and compensation prior to the construction of dam so that all stakeholders know the detail and what to expect or contribute toward the compensated package in cash and in kind. The resettlement costs must c over all inundated properties as well as emotional and psychological cost which is often ignored. The package aside covering individual cost could also be extended to cover basic facilities and infrastructure development such as roads, health centers, schools, potable water, etc. On the other hand environmental damage could always be factored into the price of electricity through ecological tax in order to reflect the true cost of power. This tax revenue could go into a standing trust fund which would be essential to sustain the programs needed to ensure the effective mitigation and compensation of environmental effects of the hydro development. To protect the integrity of the lake, measures should be taken to check deforestation by protecting the original forests. Additional compensatory measures may include either trust fund established through grants from developers (for example Harvey Basin Restoration Trust, Australia) or trust funds that manage parts of the revenue stream and for environmental purposes. This latter model was proposed for the planned Nam Theun II dam in Laos, with the intention of creating and managing a National Park in the catchment. The plan has the potential to benefit both forest ecosystems and the lifespan of the dam through reduce d sedimentation. This approach could certainly benefit Ghanas fight against deforestation. In the planning stages of a dam construction, is very important project teams realize the need to maintain adequate water flows and other habitat conditions to sustain river health and associated ecosystem services in river reaches located downstream of dams. When ecosystem services valued by local communities are fully considered and integrated along with all other management objectives, the prospects for optimizing both dam- and ecosystem-related objectives would be greatly enhanced. Project teams can help avoid the loss of ecosystem services by considering environmental flow needs at the very earliest stages of hydropower dam as part of the EIA development. The specification and provision of environmental flows is key to sustainable hydropower development and water management (Scudder, 2005). When environmental flow needs are assessed scientifically, water managers and hydropower dam planners and operators will understand the extent to which historical water flow patterns can be a ltered by hydropower operations without compromising a rivers health and associated social benefits. Active and early engagement of relevant water managers and dam planners, scientists, and other stakeholders in the planning process will help build a strong and influential constituency and foster a coordinated and consistent vision for the protection and management of a river. (Pingle et al., 2000; Craig, 2000, Anderson et al., 2006a, b Raschid-Sally et.al 2008) With proper input from stakeholders and attention to the needs and values of diverse interests, a tradeoff analysis can be undertaken to explore the optimal balancing of interests (Raschid-Sally et.al 2008) One current approach the VRA and other operator of dams on the Volta basin is the management of flood to limit its impact. New Dams and even old ones must can be designed or altered for multiple purposes such as flood control and HEP generation. By storing some portion of floodwaters on the floodplain instead of a reservoir, the total volume of necessary flood storage space in the reservoir can be reduced. By protecting or reactivating downstream floodplain areas or allowing agricultural areas to be flooded occasionally, the flood storage requirement in the upstream reservoir can often be reduced substantially. The excess water can be reallocated for hydropower use, water supply, or improved environmental flows downstream of the dam. Reflooding of natural floodplains can bring substantial ecological benefits, such as providing additional spawning and feeding opportunities for fish and enabling the floodwaters to fertilize and moisten floodplain areas used for agriculture or grazing.( Craig, 2000) Likewise , the coordinated operations of cascades of dams: on the Volta river can maximize power generation at upstream dams to enable lower dams to serve more of a re-regulating function, thereby minimizing flow alterations in the downstream river. Currently this approach is been developed by the transboundary water management Volta Basin Authority (VBA) and it is hope the implementation of such approach would be beneficial to the basin communities. The VBA IWMR policies would be the key to protecting the ecosystem in the basin. In terms of operational mode management The VRA can increase its generation of electricity from its Thermal plant in Aboase to ease the pressure on operating

Marc Reisners Coming Undammed :: Environmental Ecology Essays

Marc Reisner's Coming Undammed A dam is a barrier constructed across a waterway to control the flow or raise the level of water. (Dictionary 1) They are put in place with much care and patience. A dam is very carefully planned out. Where they are going to be placed? What type of soil it is going to be constructed in? When the plans are drawn out, every detail is gone over with a fine tooth comb. Marc Reisner has written an essay titled Coming Undammed, is an essay about him talking how he supports dam removals across the country. He has made some ideas about why he sustains his opinion, some of which I agree with, but mainly I oppose. He starts off by talking about a dam that he had visited on the Elwha River, which has two dams within it. In the upper part of the river, the Glines Canyon dam, and in the lower dam just called the Elwha. His first point against the building of dams is how the silt in the ground surrounding this dam has begun to leak into the dam. Which he says will lead to big slurrying of the water and will eventually â€Å"add millions of dollars to the cost of decommissioning.† (Reisner 382) This may be the case, but is only the case in this instance that he has come across. The ground of all other dams is not made up of the same material as every other dam in the nation. The dirt in New York doesn’t have the same makeup as the dirt of the Hoover dam in Nevada. The next idea that he had for opposing dams are the expunging of fisheries where the dams are. He gave the example of how â€Å"before the dams went in, the Elwha River churned out salmon as the Chesapeake Bay did crabs.† (Reisner 382) He also goes on to say that the fish were large and there were several types of fish with in the river. He concludes this point by saying that when the dams were built up, it shut off the fish habitation within the river and reducing the fish numbers. I agree that with him that the number of fish would be decreased with a dam being built. I think that the amount wouldn’t be that high to cause a major problem.

The Cons of Factory Farming :: Factory Farming

What if you were born to die and live a miserable, torturous life in between? This is everyday life for animals on factory farms. Factory Farming is a system of rearing livestock using intensive methods, by which poultry, pigs or cattle are confined indoors under strictly controlled conditions. [add in citation for definition] Factory farming isn’t only inhumane, but it’s also hurting our health, and we don’t even have the slightest clue. With our culture today, we believe whatever the media tells us; we trust them. Each and every year, the meat industries put mounds of money into advertising, brainwashing us and telling us what food we should eat. They run their advertisements on the television, radio, and Internet ads, and have even partnered with schools in exchange for free educational resources. We like to imagine that the meat we are eating was once free, happy, and had a fast death. But that is a lie. If we don’t do anything, who will? Did you kno w that more than 19 million animals are killed every hour? That means 19,011 animals are killed per minute (2013d). Animals in factory farms are born, raised, and slaughtered in confined buildings. They are never allowed out to run, to enjoy life. They are born to be killed and tortured in-between. This isn’t just about one farm animal, but a variety of them. +++ Last sentence is unnecessary, include in other sentences to tie in what different animals AND how it’s effecting humans. ++THESIS STATEMENT. ☠º Chickens are one of the top most tortured animals in factory farms. Farmers get the most money for chickens that are heavier and have enlarged thighs and breasts. Like most factory farmed animals, broiler chickens are raised in overcrowded cages their entire life, and become very aggressive. Because of this aggressiveness the employees of the farms cut of their beaks and toes without any type of painkiller or an anesthetic just to keep them from fighting. After being â€Å"debeaked† some chickens are then not able to eat and starve. Layer chickens lay 90-95% of the eggs sold in the U.S. (2013b) The torture starts the day they are born. Chicks are placed on a belt, where an employee than picks up each chick to see if it is a male or female. Newborn male chicks are thrown into trash bags, ground up alive, crushed, and killed many other inhumane ways.

Principles of Transportation Economics

All through the phase of airline regulation, the government set airline faires and regulated an air carrier's entry into and exit from particular markets. Assuming that the incumbent airlines made economic profits while they were regulated, what impact, if any, did the government's regulation of routes have upon air carrier's ability to make profits?Transportation economics is considered as the analysis of the share of carrying wherewithals so as to come across the necessities of the general public (Encyclopà ¦dia Britannica Online, 2007). In a broader sense, delivery pursuits create a segment of a state’s entire trade and industry items for consumption and take part in the responsibility of constructing or intensification of a countrywide or local economy and as a stimulus in the progress of assets.With the hauling precautions direction, there is a constraint that the travelers must hand over a boarding documentation ahead of going through zones outside safekeeping checkpoin ts. Numerous airlines recently proffer passengers the means of departing through the net and producing lodging permits or licenses prior to leaving.Due to government intervention, the imposition of government faires will consequentially affect the fees of airline carriers’ consumers. They will be compelled of taxes, charges, and additional costs on matters such as fuel, airport rents, aircraft financing, which will be reflective and increase the prices that they will be paying for (Hardisty, 2003). And therefore, will have a lower demand for the airline services.This may indeed affect the income of the incumbent airlines since their transactions are regulated. Consumers of their service will eventually hold back their use of the airline service since there are a lot of barriers to entry as stated by Palmby (1995). The former ease of access was lessened. For these reason, people will not be able to bring some things that they usually carry or transport.Additionally as discusse d by the Federal Aviation Administration (FAA) and Optimal Solutions and Technologies (OST) in 1999, on account of the government intervention, the administration of airline carriers will have fewer opportunities to improve their systems and just depend on the established government regulation of airlines. Significant losses can be incurred by the managing airlines and they tend to stay extremely susceptible to drop in airline interchange. Their pecuniary chances have gone through noteworthy stumbling blocks.However, although the government regulation of routes has a negative impact upon the air carrier’s ability to make profits, it has also a positive impact in return.Some terrorist attacks through air carriers may be prevented, hence, the management of air carriers does not have to spend money on possible damages that terrorism may have caused (Potter, 2006). Aside from that, together with the cooperation that the management of air carriers is receiving from the government, the running institution may have a directory or catalog of legal persons who may possibly avail of their services. Therefore, the management of air carriers does not have to spend their resources on tracking some unauthorized and illegal passengers. Furthermore, because of authority supervision, there will be more convenient gate assignments (and less reassignments); as a result, more people may eventually avail of the airline services despite higher costs of transport. These sets of incidences cyclically may contribute to beneficial return of earnings to the airline managements.Even though there is a prevailing acquisition and implementation of government regulation in airline carriers, with proper and appropriate administration of their managements, they will be more likely to have a good return in the running government regulation or will be able to have better accumulation of profits.References:FAA/OST Task Force Study (1999).

Perfect competition Essay

Monopoly is the final type of market structure in which a single seller dominates trade in a good or service for which buyers can find no close substitutes. A monopoly is distringuished from a monospony, in which there is only one buyer of a product or service. It can also have a monopsony control of a sector of a market. All types of Monopolies can be established by a government, form by integration. The way Monopoly derive their market power is from a berrier to entry. There are three major tpes of barriers to entry which are the economic, legal, and deliberate. Im going to tell you how each one works and what it is helpful more. First, the economic barriers include economies of scale, capital requirements, cost advantages, and the technological superiority. Secondly, are the Legal barriers. It can provide opportunity to monopolise the marker of a good. Lastly, is the Deliberate actions whivh a company has been wanting to monopolise a market may engage in various types of deliberate action to exclude competitos or eliminate competition. Market structures are very important in Monopoly. It provides he basis topics such as industrial organization and economics of regulation. Traditional economic analysis, perect competition, monopolictic competition, oligololy, and monopoly are the four types of market structures. Monopoly versus competitive markets is a challenge. They are similar due to the fact that they both minimize costs and maximize profit. Presiding over eachothers territory can cost millions. Many governments regulate monopolies because a monopoly market lacks the benefts of competition. The U. S. Governement appiles laws against monopoly behavior by Microsoft not allowing big companies in some industries. The Government permits certain monoplies in exchange for regulating their activites. A pure monopoly has the same exact economic retionailty of perfectly competitive companies. Total revenue and total cost maximizes a monopol over a chose of the cost.
