How successful can the management of fragile environments can be?

How successful undersurface the management of thin environments be, habituated the constant and increase demand for their exploitation? A fallible environment is an atomic number 18a where the flora and puppet have adapted to a specific climate and evolved to occupy many different niches due to extremely high competition for resources. Further much due to the constant abiotic conditions, specialisation and symbiotic relationships have occurred to much(prenominal) a degree that even the s wretched-calest ecological or environmental disruption passelnot be accommodated, meaning individual habitats and ecosystems can be easily destroyed.This combination of specialisation and interdependence add-ons the over in all fragility and vulnerability of this biome Fragile environments can be exploited in different ways, and for different reasons. For typesetters case the virago Rainforest, an equatorial tropical rain forest biome, has been significantly exploited for its agricultura l potential and natural resources cattle ranching, soy sauce bean and palm embrocate plantations, excavation and timber. The close significant consequence of these forms of exploitation is deforestation.There are many management strategies to combat deforestation, everyday choices are legislation, ecotourism, selective logging and various tree regeneration designs. In this essay I volition assess the extent to which these management schemes are successful in terms of sustainability and environmental effectiveness, in light of inevitable increasing anthropogenic pressures on tropical biomes roughly the world. Firstly it is important to identify how fragile environments are exploited and for what gain. If we look at the Amazon Rainforest, one of the major forms of exploitation is land for cattle ranching.Vast expanses of the rainforest are deforested to touch way for grassland to rear cattle. This form of exploitation was responsible for 80% of all Amazonian deforestation in 2009, due to the ever increasing spherical demand for beef as a new wave of middle classes emerge from developing nations with a first world diet. Large soya bean plantations run by major agricultural TNCs like Cargill in the Amazon add-on its land for plantations at rates of 1. 3 million hectares every year. brazil nut is one of the worlds top producers of soya bean.The expansion of this market is driven by low transportation costs from change infrastructure (both in and out of the Amazon) and increasing international demands for livestock feed where China is one of the principal(prenominal) consumers, due to rapid scotch growth (9% each year) and high demand from its emerging middle classes. The creation of capacious mechanised soy monocultures has already been the sole cause of 21 million hectares of deforested rainforest in Brazil and 80 million hectares from the Amazon as a whole, since the early 1970s.While these industries stated above as wholesome as mining and loggi ng have contributed to 240,000km2 of deforestation in the Amazon, the hunting for bush meat by native Amazonian tribes has put considerable pressure on rainforest fauna. Since the late 1990s Brazilian Amazon local anaesthetic people consume amongst 2. 2 to 5. 4 million primates each year. This member is unsustainable as the primates reproduce at a much slower rate than they are consumed. just some of these primates are endangered, meaning reproduction is inherently slower.There is often a conflict of interests between the exploitation and conservation of fragile environments. Thus in order for a fragile environment to be managed successfully a balance must be established. However, in reality this can be voiceless to achieve. It is often the case that many countries depend on natural resources from fragile environments for income and trade on the world(prenominal) markets thus qualification fragile environments an integral part of their economy. This is the case with many LEDC s, who are reluctant to discover exploiting their activities for fear it will result in economic aggravate and slower development.In Brazil for example, much of the mining industry that takes place in the Amazon brought in $9 billion to the country in 2006. moreover it can be a misunderstanding that most people, who exploit fragile environments like through mining in the Amazon, are doing so out of choice. As most locals have no other attainable alternative to generate income for their families. Furthermore endemical peoples often receive little education regarding orbiculate personal matters and may not recognise the need for conservation. In addition it is rare that a single fragile environment is endemic to one country, as they often span over several territories.A good example is the Amazon rainforest which lies within Brazil, holding 60% of the forest, Peru 13%, Columbia 10% and with Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana as well holding small am ounts. This makes it difficult to establish a uniform strategy across the whole are, and do harder still by low funds functional for conservation in many of these countries.One of the more popular forms of conservation management is conservation reserves that protect biodiversity and ensure its population livessustainably with their environment. One example of much(prenominal) a scheme is the Central Amazon Conservation complex in the Brazilian Amazon. Established in 2003, it brings together four reserves in the Amazon Jau National Park, Anavilhanas Ecological Station, Mamiraua Reserve and Amana reserve, a native area of 49,000 km2. Sustainable development reserves have protected areas from developments that could have seriously damaged the CACC. Dams, pipelines, mines and commercialised logging projects have all been prevented from entering the area.These reserves have improved biodiversity and caused a 100% increase in the black caiman population, and a 300% increase in the pirarucu fish. Economic Alternatives Programs promote sustainable activities whereby local people who make goods from the forests natural resources can sell directly to buyers without tone ending through middle men who charge a commission. Thus ensuring a decent income, preventing any local farmers giving up land to major commercial agricultural firms, where the land is likely to be deforested and indigenous communities displaced.Overall the economics alternative program has reduced poverty, increasing household incomes by 50-99%. However this protecting such a large area can be difficult. The vastness of the area means it is majorly understaffed, thus making the control and regulation of illegal activities difficult. Only 100 volunteer guards and 150 employed members of staff are present in the Amana and Mariraua reserves combined area of 2,490,000 hectares of land. The size of the protected areas and the number of staff available makes it is very difficult to prevent access int o the reserves.In Jau National park, an area of 2,272,000 hectares, therere only 4 indissoluble members of staff. Thus fish and turtle poaching remains an unresolved problem. As populations increase around peripheral settlements, more stress is put on it to satisfy the demands of the populations, for example many towns in the lovingness of the rainforest suffer from intensive poaching of primates and manatees. Overall it may seem that despite efforts, and and then success, of implementing such conservation schemes, may decrease in effectiveness following growing demand for the Amazons resources from increasing population pressure.Ecotourism is also a popular way of generating income for the local people as well as promoting conservation. It is a popular method of generating income in developing countries without billion dollar investments. Local people can act as guides or be providers of transport and accommodation creating a source of income. The environmental low impact theme and conservation awareness can potentially bring in public and surreptitious investment. In addition it is a more environmentally friendly form of drill compared to other occupations such as logging and commercial agriculture.Plus if the country makes the economic transition from a manufacture to service area economy, the government will have an indirect economic incentive to conserve the environment through promoting ecotourism. Ecotourism has already proved to be an economic, environmental and social success. For example, Costa Rica has been pumping in US$1. 6 million annually since 2000 from ecotourism, resulting in jobs for local people and 25% of its land under government protection. GNP per capita rose from $1500-$2000 between 1978 and 1992.The village of Tortuguero, Costa Rica, a satellite settlement to the Talamancan national park took a survey which indicated that 88% were highly satisfied with the multiplier effects from ecotourism in the park such as local employment empowerment and government funding into building eco lodges on old farmland in the village attracting tourists to pass by in their local economy. However, there are cases where ecotourism has not benefitted the local community or the country as a whole.It is often the case that an ecotourism service is provided by an international agent, whereby revenue is repatriated overseas, away from the local community. notwithstanding even if the service is provided by host nation companies, the jobs can be seasonal, menial and in most cases, low paid. The influx of wealth and foreign exchange can shift political and economic conditions to make the country or area dependant on tourism as opposed to domestic economic practises. This induces a degree of instability to the industry, making it vulnerable to sudden economic change, such as the global financial crisis in 2008.This can create a lack of demand and subsequent economic decline in the area and ultimately forcing the local population in to occupations that unsustainably exploit natural resources. In conclusion, it is can be said with a degree of confidence that most schemes are beneficial to an extent. Land which is protected, conserved and managed sustainably outweighs the possible environmental damage that can occur due to poor management and lack of funding towards the scheme. what is more it is the schemes which involve the local community that have the biggest potential to be successful.Managing the environment whereby its inhabitants are able to absorb the full economic benefits of its natural resources allows growth, development and investment into the local economy Thus resulting in a self-sustaining operation. However, as world population is not yet set to peak until 2050, the pressure on the environment and demand for resources is only set to increase. It is also worth noting that in the light of possible changes to our global climate system in the coming decades there will be an even greater brat to the Earths fragile environments.With the effects of anthropogenic induced climate change causing more extreme weather, the constant abiotic factors that have shaped our fragile environments across the globe face a deadly, permanent change. If we are to preserve any type of fragile environment at all, it could be argued that a global effort to reduce our carbon footprint would be the most successful long term scheme to ensure the survival of the Earths biodiversity.
