Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become arid. It is the spread of arid areas caused by a variety of factors, such as overexploitation of soil as a result of human activity and the effects of climate change. Geographic areas most affected include the Sahel region in Africa, the Gobi Desert and Mongolia in Asia as well as parts of South America. Drylands occupy approximately 40–41% of Earth's land area and are home to more than 2 billion people.
The International Organization for Migration (IOM) is the principal United Nations Related Organization working in the field of migration. The organization implements operational assistance programmes for migrants, including internally displaced persons, refugees, and migrant workers.
"Human migration is the movement of people from one place in the world to another.".
An internally displaced person (IDP) is someone who is forced to leave their home but who remains within their country's borders. They are often referred to as refugees, although they do not fall within the legal definitions of a refugee.
Forced displacement is an involuntary or coerced movement of a person or people away from their home or home region. The UNHCR defines 'forced displacement' as follows: displaced "as a result of persecution, conflict, generalized violence or human rights violations".
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of 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. Environmental degradation process amplify the impact of environmental issues leave lasting impacts on the environment.
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.
Development-induced displacement and resettlement (DIDR) occurs when people are forced to leave their homes in a development-driven form of forced migration. Historically, it has been associated with the construction of dams for hydroelectric power and irrigation, but it can also result from various development projects such as mining, agriculture, the creation of military installations, airports, industrial plants, weapon testing grounds, railways, road developments, urbanization, conservation projects, and forestry.
Norman Myers was a British environmentalist specialising in biodiversity and also noted for his work on environmental refugees.
The Kampala Convention is a treaty of the African Union (AU) that addresses internal displacement caused by armed conflict, natural disasters and large-scale development projects in Africa.
Sudanese refugees are persons originating from the country of Sudan, but seeking refuge outside the borders of their native country. In recent history, Sudan has been the stage for prolonged conflicts and civil wars, as well as environmental changes, namely desertification. These forces have resulted not only in violence and famine but also the forced migration of large numbers of the Sudanese population, both inside and outside the country's borders. Given the expansive geographic territory of Sudan, and the regional and ethnic tensions and conflicts, much of the forced migration in Sudan has been internal. Yet, these populations are not immune to similar issues that typically accompany refugeedom, including economic hardship and providing themselves and their families with sustenance and basic needs. With the creation of a South Sudanese state, questions surrounding southern Sudanese IDPs may become questions of South Sudanese refugees.
Climate change is a critical issue in Bangladesh as the country is one of the most vulnerable to the effects of climate change. In the 2020 edition of Germanwatch's Climate Risk Index, it ranked seventh in the list of countries most affected by climate calamities during the period 1999–2018. Bangladesh's vulnerability to the effects of climate change is due to a combination of geographical factors, such as its flat, low-lying, and delta-exposed topography, and socio-economic factors, including its high population density, levels of poverty, and dependence on agriculture. The impacts and potential threats include sea level rise, temperature rise, food crises, droughts, floods, and cyclones.
Human rights and climate change is a conceptual and legal framework under which international human rights and their relationship to global warming are studied, analyzed, and addressed. The framework has been employed by governments, United Nations organizations, intergovernmental and non-governmental organizations, human rights and environmental advocates, and academics to guide national and international policy on climate change under the United Nations Framework Convention on Climate Change (UNFCCC) and the core international human rights instruments. In 2022 Working Group II of the IPCC suggested that "climate justice comprises justice that links development and human rights to achieve a rights-based approach to addressing climate change".
A refugee crisis can refer to difficulties and dangerous situations in the reception of large groups of forcibly displaced persons. These could be either internally displaced, refugees, asylum seekers or any other huge groups of migrants.
Ulysses syndrome is an atypical set of depressive, anxious, dissociative, and somatoform symptoms that results from being exposed to extreme levels of stress unique to the process of modern migration. Rather than a mental disorder, this syndrome is a natural reaction to toxic levels of stress seen in migrants who are otherwise in normal mental health.
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.
The flagship publication series of the International Organization for Migration, the World Migration Report presents data and information on human migration together with analysis of complex and emerging migration issues.
Climate migration is a subset of climate-related mobility that refers to movement driven by the impact of sudden or gradual climate-exacerbated disasters, such as "abnormally heavy rainfalls, prolonged droughts, desertification, environmental degradation, or sea-level rise and cyclones". Gradual shifts in the environment tend to impact more people than sudden disasters. The majority of climate migrants move internally within their own countries, though a smaller number of climate-displaced people also move across national borders.
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.
Jane Alexandra McAdam is an Australian legal scholar, and expert in climate change and refugees.
