Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage.
Desertification is a type of gradual land degradation of fertile land into arid desert due to a combination of natural processes and human activities.
Senegal, officially the Republic of Senegal, is the westernmost country in West Africa, situated on the Atlantic Ocean coastline. Senegal is bordered by Mauritania to the north, Mali to the east, Guinea to the southeast and Guinea-Bissau to the southwest. Senegal nearly surrounds The Gambia, a country occupying a narrow sliver of land along the banks of the Gambia River, which separates Senegal's southern region of Casamance from the rest of the country. Senegal also shares a maritime border with Cape Verde. Senegal's economic and political capital is Dakar.
Senegal is a coastal West African nation located 14 degrees north of the equator and 14 degrees west of the Prime Meridian. The country's total area is 196,190 km2 of which 192,000 km2 is land and 4,190 km2 is water.
The Global Environment Facility (GEF) is a multilateral environmental fund that provides grants and blended finance for projects related to biodiversity, climate change, international waters, land degradation, persistent organic pollutants (POPs), mercury, sustainable forest management, food security, and sustainable cities in developing countries and countries with economies in transition. It is the largest source of multilateral funding for biodiversity globally and distributes more than $1 billion a year on average to address inter-related environmental challenges.
Land degradation is a process in which the value of the or biophysical or biochemical environment is affected by a combination of natural or 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.
Environmental issues in Haiti include a historical deforestation problem, overpopulation, a lack of sanitation, natural disasters, and food insecurity. The major reasons for these environmental issues are corruption, human exploitation, and the embezzlement of taxpayers' funds for personal gains. In addition, 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.
African environmental problems are problems caused by the direct and indirect human impacts on the natural environment and affect humans and nearly all forms of life in Africa. Issues include deforestation, soil degradation, air pollution, water pollution, coastal erosion, garbage pollution, climate change, Oil spills, Biodiversity loss, and water scarcity. These issues result in environmental conflict and are connected to broader social struggles for democracy and sovereignty. The scarcity of climate adaptation techniques in Africa makes it the least resilient continent to climate change.
The extensive and rapid clearing of forests (deforestation) within the borders of Nigeria has significant impacts on both local and global scales.
Rates and causes of deforestation vary from region to region around the world. In 2009, two-thirds of the world's forests were located in just 10 countries: Russia, Brazil, Canada, the United States, China, Australia, the Democratic Republic of the Congo, Indonesia, India, and Peru.
Climate change in Africa is an increasingly serious threat as Africa is among the most vulnerable continents to the effects of climate change. Some sources even classify Africa as "the most vulnerable continent on Earth". Climate change and climate variability will likely reduce agricultural production, food security and water security. As a result, there will be negative consequences on people's lives and sustainable development in Africa.
There are many pressing environmental issues in Mongolia that are detrimental to both human and environmental wellness. These problems have arisen in part due to natural factors, but increasingly because of human actions. One of these issues is climate change, which will be responsible for an increase in desertification, natural disasters, and land degradation. Another is deforestation, which is expanding due to human activity, pests, disease, and fires. Mongolian lands are becoming more arid through desertification, a process that is being exacerbated due to irresponsible land use. Additionally, more and more species are disappearing and at risk for extinction. Moreover, especially in population centers, Mongolians deal with air and water pollution caused by industrialization.
Climate change in Senegal will have wide reaching impacts on many aspects of life in Senegal. Climate change will cause an increase in average temperatures over west Africa by between 1.5 and 4 °C by mid-century, relative to 1986–2005. Projections of rainfall indicate an overall decrease in rainfall and an increase in intense mega-storm events over the Sahel. The sea level is expected to rise faster in West Africa than the global average. Although Senegal is currently not a major contributor to global greenhouse gas emissions, it is one of the countries most vulnerable to climate change.
Due to its geographical and natural diversity, Indonesia is one of the countries most susceptible to the impacts of climate change. This is supported by the fact that Jakarta has been listed as the world's most vulnerable city, regarding climate change. It is also a major contributor as of the countries that has contributed most to greenhouse gas emissions due to its high rate of deforestation and reliance on coal power.
The United Nations Decade on Ecosystem Restoration runs from 2021 to 2030. Similar to other nature related international decades, its purpose is to promote the United Nation's environmental goals. Specifically, to facilitate global cooperation for the restoration of degraded and destroyed ecosystems. Along with fostering efforts to combat climate change, safeguard biodiversity, food security, and water supply. While much focus is on promoting restoration activity by national governments, the UN also wishes to promote such efforts from other actors, ranging from the private sector and NGOs to regular individuals.
Climate Change in Nigeria is evident from temperature increase, rainfall variability. It is also reflected in drought, desertification, rising sea levels, erosion, floods, thunderstorms, bush fires, landslides, land degradation, more frequent, extreme weather conditions and loss of biodiversity. All of which continues to negatively affect human and animal life and also the ecosystems in Nigeria. Although, depending on the location, regions experience climate change with significant higher temperatures during the dry seasons while rainfalls during rainy seasons help keep the temperature at milder levels. The Effects of Climate Change prompted the World Meteorological Organization, in its 40th Executive Council 1988, to establish a new international scientific assessment panel to be called the International Panel on Climate Change (IPCC). The 2007 IPCC's fourth and final Assessment Report (AR4) revealed that there is a considerable threat of Climate Change that requires urgent global attention. The report further attributed the present global warming to largely anthropogenic practices. The Earth is almost at a point of no return as it faces environmental threats which include atmospheric and marine pollution, global warming, ozone depletion, the dangers of pollution by nuclear and other hazardous substances, and the extinction of various wildlife species.
Natural disasters in Nigeria are mainly related to the climate of Nigeria, which has been reported to cause loss of lives and properties. A natural disaster might be caused by flooding, landslides, and insect infestation, among others. To be classified as a disaster, there is needs to be a profound environmental effect or human loss which must lead to financial loss. This occurrence has become an issue of concern, threatening large populations living in diverse environments in recent years.
The Algerian Green Dam refers to a project initiated in Algeria in the 1960s to plant millions of trees to stop desertification, specifically to prevent the northward advancement of the Sahara Desert.
Desertification in Africa is a form of land degradation that involves the conversion of productive land into desert or arid areas. This issue is a pressing environmental concern that poses a significant threat to the livelihoods of millions of people in Africa who depend on the land for subsistence. Geographical and environmental studies have recently coined the term desertification. Desertification is the process by which a piece of land becomes a desert, as the word desert implies. The loss or destruction of the biological potential of the land is referred to as desertification. It reduces or eliminates the potential for plant and animal production on the land and is a component of the widespread ecosystem degradation. Additionally, the term desertification is specifically used to describe the deterioration of the world's drylands, or its arid, semi-arid, and sub-humid climates. These regions may be far from the so-called natural or climatic deserts, but they still experience irregular water stress due to their low and variable rainfall. They are especially susceptible to damage from excessive human land use pressure. The causes of desertification are a combination of natural and human factors, with climate change exacerbating the problem. Despite this, there is a common misconception that desertification in Africa is solely the result of natural causes like climate change and soil erosion. In reality, human activities like deforestation, overgrazing, and unsustainable agricultural practices contribute significantly to the issue. Another misconception is that, desertification is irreversible, and that degraded land will forever remain barren wastelands. However, it is possible to restore degraded land through sustainable land management practices like reforestation and soil conservation. A 10.3 million km2 area, or 34.2% of the continent's surface, is at risk of desertification. If the deserts are taken into account, the affected and potentially affected area is roughly 16.5 million km2 or 54.6% of all of Africa. 5.7 percent of the continent's surface is made up of very severe regions, 16.2 percent by severe regions, and 12.3 percent by moderate to mild regions.
The majority of Ghana's income and jobs are produced directly and indirectly by the land, which is a vital resource for our nation's prosperity. It sustains the provision of ecosystem services as well as the agricultural, forestry, and fishing livelihoods of the vast majority of people, particularly those living in rural areas. Despite these advantages, there are a number of temporal and spatial factors contributing to the degradation of our land resources, such as deforestation, erosion, declining soil fertility and productivity, deterioration of rangelands, desertification, and deterioration of water bodies.
