Environmental degradation is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. As indicated by the I=PAT equation, environmental impact (I) or degradation is caused by the combination of an already very large and increasing human population (P), continually increasing economic growth or per capita affluence (A), and the application of resource-depleting and polluting technology (T).
Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable. Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bush fires.
Land development is altering the landscape in any number of ways such as:
Environmentally, Colombia is a mega-diverse country from its natural land terrain to its biological wildlife. Its biodiversity is a result of its geographical location and elevation. It is the fourth largest South American country and only country in South America to have coasts on the Pacific and Caribbean Sea. Colombia's terrain can be divided into six main natural zones: The Caribbean, the Pacific, The Orinoco region, The Amazonia region, the Andean region, and the Insular region. 52.2% of the environment is predominately the Andes, Amazon, and Pacific Basins, followed by the Orinoco basin 13.9%, the Andes and the Caribbean. The Tropical Andes, Choco, and the Caribbean are considered biodiversity hotspots which puts these areas at high risk of concentration of colonizing activities. Colombia hosts over 1800 species and at least one new species is detected every year. Decades of civil war and political unrest has impeded biological and environmental research in Colombia. The political unrest in Colombia catalyzes the alteration of land patterns through the cultivation of coca and opium crops, the redirection of extractive activities, and land abandonment in some areas.
Environmental issues in Haiti include an historical deforestation problem, overpopulation, a lack of sanitation, natural disasters, and food insecurity. A major reason for these environmental issues is that there is not sufficient protection or management of the country's natural resources. Other environmental issues, such as decreases in precipitation and more severe natural disasters, will likely arise in Haiti as a result of climate change. Experts agree that Haiti needs to adopt new policies to address both the issues that already exist and to prepare for the effects of climate change.
Environmental issues in Kenya include deforestation, soil erosion, desertification, water shortage and degraded water quality, flooding, poaching, and domestic and industrial pollution.
Environmental pollution in Nepal include overpopulation, deforestation, energy and species conservation.
African environmental issues are caused by anthropogenic effects on the African natural environment and have major impacts on humans and nearly all forms of endemic life. Issues include desertification, problems with access to safe water supply, population explosion and fauna depletion. These issues are ultimately linked to over-population in Africa, as well as on a global scale. Nearly all of Africa's environmental problems are geographically variable and human induced, though not necessarily by Africans.
Kohalpur is a municipality in Banke District of province no 5 of Nepal. The municipality was established on 18 May 2014 merging the existing two Village Development Committees i.e. Rajhena and Kohalpur. The town is in East-West highway and one of the fastest developing places in Nepal. A neighboring city Nepalgunj is on South (16 km), with Ghorahi city (135 km) to west in Dang District and further 6 km is the Indian border. In fact it is a growing city in the western region of Nepal. It has a junction to diverse the roadway transport to east, west, north and south from the city.
Deforestation during the Roman period was a result of the geographical expansion of the Roman Empire, with its increased population, large-scale agriculture, and unprecedented economic development. Roman expansion marks the transition in the Mediterranean from prehistory to the historical period beginning around 500 BC. Earth sustained a few million people 8,000 years ago and was still fundamentally pristine, but Rome drove human development in Western Europe and was a leading contributor of the deforestation around the Mediterranean.
Deforestation is one of the most serious environmental issues in Sri Lanka. In the 1920s, the island had a 49 percent forest cover but by 2005 this had fallen by approximately 26 percent. Between 1990 and 2000, Sri Lanka lost an average of 26,800 ha of forests per year. This amounts to an average annual deforestation rate of 1.14%. Between 2000 and 2005 the rate accelerated to 1.43% per annum. However, with a long history of policy and laws towards environmental protection, deforestation rates of primary cover have actually decreased 35% since the end of the 1990s thanks to a strong history of conservation measures. The problem of deforestation in Sri Lanka is not as significant in the southern mountainous regions as it is in northern and lowland southern Sri Lanka, largely due to the nature of environmental protection.
The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. The environmental impact of agriculture varies based on the wide variety of agricultural practices employed around the world. Ultimately, the environmental impact depends on the production practices of the system used by farmers. The connection between emissions into the environment and the farming system is indirect, as it also depends on other climate variables such as rainfall and temperature.
Deforestation in Madagascar is an ongoing environmental issue. Deforestation creates agricultural or pastoral land but can also result in desertification, water resource degradation, biodiversity erosion and habitat loss, and soil loss.
Rudrasagar Lake, also known as Twijilikma, is a lake located in Melaghar, Tripura, India.
Cuba has an environment which includes very wide variety of different natural habitats and is home to large number of species, many of them endangered. Since the arrival of European settlers Cuba has suffered from deforestation as a result of more and more forest area being taken over by humans to use them for agricultural production. Also cutting down trees for firewood and to obtain materials for building has contributed to the loss of forests and extinction of some species. Environmental awareness has since increased in Cuba and in the late 1990s and in the 2000s Cuban government has started new programs to protect the environment and to increase forest coverage.
Deforestation is one of the main contributors to climate change. It comes in many forms: wildfire, agricultural clearcutting, livestock ranching, and logging for timber, among others. Forests cover 31% of the land area on Earth and annually 75,700 square kilometers of forest is lost. Mass deforestation continues to threaten tropical forests, their biodiversity and the ecosystem services they provide. The main area of concern of deforestation is in tropical rainforests, since it is home to the majority of the biodiversity. Organisations such as World Wildlife Fund focus on the preservation of nature and the reduction of the most pressing threats to the diversity of life on Earth.
Environmental issues in Sri Lanka include large-scale logging of forests and degradation of mangroves, coral reefs and soil. Air pollution and water pollution are challenges for Sri Lanka since both cause negative health impacts. Insufficient waste management, especially in rural areas, leads to environmental pollution. Sri Lanka is also vulnerable to climate change impacts such as extreme weather events and sea level rise.
