Desertification is a type of gradual land degradation of fertile land into arid desert due to a combination of natural processes and human activities.
Zimbabwe is a landlocked country in southern Africa lying north of the Tropic of Capricorn. During summer, the whole country experiences warm temperatures as a result of the sun being directly overhead. It straddles an extensive high inland plateau that drops northwards to the Zambezi valley where the border with Zambia is and similarly drops southwards to the Limpopo valley and the border with South Africa.
Mauritania, a country in the Western Region of the continent of Africa, is generally flat, its 1,030,700 square kilometres forming vast, arid plains broken by occasional ridges and clifflike outcroppings. Mauritania is the world’s largest country lying entirely below an altitude of 1,000 metres (3,300 ft). It borders the North Atlantic Ocean, between Senegal and Western Sahara, Mali and Algeria. It is considered part of both the Sahel and the Maghreb. A series of scarps face southwest, longitudinally bisecting these plains in the center of the country. The scarps also separate a series of sandstone plateaus, the highest of which is the Adrar Plateau, reaching an elevation of 500 metres or 1,640 feet. Spring-fed oases lie at the foot of some of the scarps. Isolated peaks, often rich in minerals, rise above the plateaus; the smaller peaks are called Guelbs and the larger ones Kedias. The concentric Guelb er Richat is a prominent feature of the north-central region. Kediet ej Jill, near the city of Zouîrât, has an elevation of 915 metres or 3,002 feet and is the highest peak.
The Hadejia-Nguru wetlands in Yobe State in northern Nigeria, which include Nguru Lake, are ecologically and economically important. They are threatened by reduced rainfall in recent years, a growing population and upstream dam construction.
The Kafin Zaki Dam is a controversial project to build a reservoir on the Jama'are River in Bauchi State in the Northeast of Nigeria.
The 2012–2013 North American drought, an expansion of the 2010–2013 Southern United States drought, originated in the midst of a record-breaking heat wave. Low snowfall amounts in winter, coupled with the intense summer heat from La Niña, caused drought-like conditions to migrate northward from the southern United States, wreaking havoc on crops and water supply. The drought inflicted significant economic ramifications for the affected states. It exceeded, in many measures, the 1988–1989 North American drought, the most recent comparable drought.
Fulani herdsmen or Fulani pastoralists are nomadic or semi-nomadic Fulani people whose primary occupation is raising livestock. The Fulani herdsmen are largely located in the Sahel and semi-arid parts of West Africa, but due to relatively recent changes in climate patterns, many herdsmen have moved further south into the savannah and tropical forest belt of West Africa. The herdsmen are found in countries such as Nigeria, Niger, Senegal, Guinea, Mauritania, Mali, Burkina Faso, Ghana, Benin, Côte d'Ivoire, and Cameroon. In Senegal, they inhabit northeastern Ferlo and the southeastern part of the country. In some of these countries the Fula constitute a minority group. They inhabit Northern Nigeria and some parts of the country.
Communal conflicts in Nigeria can be divided into two broad categories:
Herder–farmer conflicts in Nigeria are a series of disputes over arable land resources across Nigeria between the mostly-Muslim Fulani herders and the mostly-Christian non-Fulani farmers. The conflicts have been especially prominent in the Middle Belt since the return of democracy in 1999. More recently, they have deteriorated into attacks on farmers by Fulani herdsmen.
In Afghanistan, climate change has led to a temperature increase of 1.8 °C since 1950. This has caused far-reaching impacts on Afghanistan, culminating from overlapping interactions of natural disasters, conflict, agricultural dependency, and severe socio-economic hardship.
In Iraq, climate change has led to environmental impacts such as increasing temperatures, decreasing precipitation, land degradation, and water scarcity. Climate change poses numerous risks to human health, livelihoods, political stability, and the sustainable development of the nation. The combination of ecological factors, conflict, weak governance, and an impeded capacity to mitigate climate change, has made Iraq uniquely at risk to the negative effects of climate change, with the UN ranking them the 5th most vulnerable country to climate change. Rising temperatures, intensified droughts, declining precipitation, desertification, salinization, and the increasing prevalence of dust storms are challenges Iraq faces due in to the negative impacts of climate change. National and regional political instability and conflict have made it difficult to mitigate the effects of climate change, address transnational water management, and develop sustainably. Climate change has negatively impacted Iraq's population through loss of economic opportunity, food insecurity, water scarcity, and displacement.
Between 2008 and early 2010, Kenya, one of the countries of Eastern Africa, was affected by a severe drought, which put ten million people at risk of hunger and caused a large number of deaths to livestock in Kenyan Arid and Semi-Arid Lands (ASALs), constituting around 88% of the country.
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.
The Fulani refers to an ethnic group, the Fulani are group of people whose neighboring farmers are against them in various ethnicities. Nigeria is considered a “melting pot” of different cultural and ethnic groups. Ethnic identification in the country is a complicated amalgamation of primordial and constructivist approaches.
Nomadic conflict, also called farmer–herder conflict, is a type of environmental conflict where farming and herding communities overlap and has been used to refer to fighting among herding communities or fighting between herding and farming communities. This is sometimes referred to as conflict involving “pastoralists” or “nomadic” people and “agriculturalists” or “settled” people. The conflicts usually arise from destruction of crops by livestock and is exacerbated during times when water and lands to graze are scarce.
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 climate of Nigeria is mostly tropical. Nigeria has three distinct climatic zones, two seasons, and an average temperature ranging between 21 °C and 35 °C. Two major elements determine the temperature in Nigeria: the altitude of the sun and the atmosphere's transparency. Its rainfall is mediated by three distinct conditions including convectional, frontal, and orographical determinants. Statistics from the World Bank Group showed Nigeria's annual temperature and rainfall variations, the nation's highest average annual mean temperature was 28.1 °C in 1938, while its wettest year was 1957 with an annual mean rainfall of 1,441.45mm.
Lesotho is a country in southern Africa that is already experiencing the negative effects of climate change, including increased frequency of extreme weather, such as droughts, increased rates of soil erosion and desertification, and reduced soil fertility. Lesotho is a landlocked country that is particularly vulnerable to the negative impacts of climate variability and changes in water and food security, as well as adverse conditions to health, human settlements, and the energy sector.
The severity of desertification in the drylands of the world made the United Nations Organization to adopt a Convention to Combat Desertification (CCD) in 1994. Nigeria approved the National Action Programme (NAP) as a primary tool for the implementation of the Convention in 1997.
Agro-Climatic Resilience in Semi-Arid Landscapes (ACReSAL) is a six-year project funded by the World Bank, aimed at restoring degraded landscapes in Northern Nigeria. The region is marked by significant challenges, including high poverty rates, low literacy levels, and an environment of fragility, conflict, and violence. The degradation of natural resources, poor agricultural productivity, and climate risks like desertification further complicate the situation. Additionally, the area suffers from poor penetration of modern technology and weak institutional capacity.
