Definition of evironmental degredation
Environmental degradation is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems and the extinction of wildlife or the decline in the production value of the available renewable and non renewable resources.
The importance of addressing environmental degredation lies is safe guarding biodiversity, mitigating climate change and ensuring clean air and water for future generation. For secure and sustainable future, it is essential to understand the causes and effect of environmental degredation and work collectively to stop it.
Causes of environmental degradation in Uganda
Population growth is one of the major causes of environmental degredation. Population growth is the increase in the number of people living in a particular region or world as whole. The population of the world in september 2021 was about 8 billion people. The annual growth rate about 1.05% or 83 million people annually. This high population directly affects environmental degredation because it puts high demand on environmental resources such as water, food and energy leading to overexploitation and depletion of nature resources. Secondly, larger population growth contributes to expansion of cities and natural areas are converted into residental and industrial areas. Lastly Large population generally generate more wastes and pollutants leading to air and water polution.
Urbanization is another cause of environemental degredation. Urbanization is a process of increasing proportion of the population that live in towns and cities. Typically urban areas have high population densities and greater population development. Urbanization has significant impact on the environment such as habitat destruction including forests, wetlands and green spaces resulting in the loss of biodiversity.and destruction of ecosystems. Urbanization also lead to land use changes converting agricultural land and open spaces into built up areas. This can lead to soil degredation and decreased agricultural productivity. Urbarnization also lead to pollution due to increased inductrialization,regular motar activities
Waste generation is another cause of environmental degredation. High popuation in urban areas resut in increased waste generation straining waste management systems leading land pollution.
Industrialization is another cause of pollution. Industrialization is development and growth of manufacturing industries characterised by adoption and advercement of industrial processes and increased production capacities. Industrialization constribute to environmental degredation through release of poisonous industrial wastes that end up and polute land,water and air. It also leads to over exploitation and depletion of natural resources such fossil fuel and other minerals. This often lead to destruction of ecosystem, deforestation and loss of biodiversity.
Improved health care has lead to population growth and cosequently overexploitation and depletion of natural resources of natural resource such deforestation
Corruption in government which fail to impose laws that protect the environment. This leads to cases such deforestation, overfishing and use of harmful fishing method and deplete the lake of fish. Also Poaching has led to extinction of valuable wildlife species such as Rhinos in Murchison National Park.
Natural phenomenoa such as natural fires, flooding, overgrazing by wildlife, pests and dieases and volcanic eraption have led to environmental degradation
Mining and quarrying is another factor that leads to environmental degredation. These not only deplete the nonrenewable natural resources but also h leave deep hollows that may harbor disease causing vectors e.g. Kilembe mine.
Political instability such as in Kasese and other parts of the worl lead environmental due to destruction of vegetation and natural habitals by explosives
Effects of environmental degredation in Uganda
Ozone depressio is one of the effects of invironmental degredation. The ozone layer protects the Earth against most utraviolet (UV) radiations coming from the sun. Too much exposure to UV rays can cause sunburn, skin cancer, and glaucoma.
Green house gas emission such as carbon dioxide lead to global warming or gradual increase in the earth’s temperature. This leads to melting of ice from the mountains where wateris stored causing flooding of rivers and lakes which leads to death and displacement of people and wildlife.
Environmental degredation has an economic impact because decreased soil productivity in agriculture and depletion of non renewable nature resources leads to increased costs of production and consequently inflation
Environmental degredation leads to loss of biodiversity through destruction of natural habitats such forests and water and air pollution.
Environmental degredation leads to losses for tourist industry through destruction of natural tourist attractions such as forests, glaciers, snow on the top mountains like Mountain Rwenzori. It also leads to extinction of
Environmental degredation impact on human health because pollution leads to high prevalence of diseases like asthema and infections such as cholera. There is also diappearance of forests that natural sources of herbs that would treat diseases like malaria
Environmental degredation has led to shortage of fuel such wood and fossil fuel and potable water.
Environmental degredation leads to Loss of water catchment areas leading to the disappearence of stream, shallow wells and swamps in places in Arua, Nakasogola and so on.
Solution to environmental degredation in Uganda
Whole ecosystems might be wiped out in long run the causes of environmental degradation are not addressed effectively. Some of the suggested solutions are
Use alternative forms of energy such as solar energy and hydroelectricity to reduce pressures on forests nd fossil fuel.
Plant trees more trees to reverse deforestation and to reverse the effects of green house emission
Alternative use of massive modes of transport such as electric trains and buses to reduce on the number of vehicle on the road and hence carbon dioxide emission
Energy conservation strategies
Dispose of our wastes appropriately
Use of fuel efficient vehicles to reduce fuel consumption
Education of the masses and children in school to understand the fundemental principle.
Recycling of wastes
Fine and purnishment for illegal dumping
Reduce and reused waste generation
In conclution it is every one obligation toconserve the environment for the future generation.
