Climate and environmental migrations are a phenomenon discussed at the various environmental forums. However, each context brings with it differences in causes and consequences. In the meantime, a response on both fronts is becoming gradually urgent, while at the international level there are increasing difficulties in reaching agreement.
Environmental and climate migrations
Climate migration in Africa is an increasingly central topic in migration debate. As early as 1990, the Intergovernmental Panel on Climate Change (IPCC), the United Nations’ scientific forum for studying global warming and its effects, noted that the greatest impact could be on human migration. Therefore, it is necessary to remember the subtle difference between environmental migration, due to direct human action (e.g. caused by environmental damage such as oil spills), and climate migration: migration caused by the meteorological impact of climate change. To clarify, it should be recalled that the scientific community has long recognised the anthropogenic origin of climate change. However, it should be specified that it is not easy to distinguish between the two types of migration and they often move in parallel, adding up in their effects on human mobility.
At the same time, the meteorological impact of climate change can be divided into two distinct migration factors: climatic processes and non-climatic factors. To the one hand, climate processes include phenomena such as rising sea levels, salinisation of agricultural land, salinisation of water and soil, desertification and increasing water scarcity, as well as climatic events such as floods and irregularities (as well as violence) in rainfall. To the other hand, non-climatic factors are political instability, population growth or community resilience to natural disasters. Finally, all these factors contribute to the degree of vulnerability that people and societies experience.
Rainfallsโ effects in Africa and climate migration
With regard to climatic migrations in Africa, an increasing irregularity of rainfall is observed in large parts of sub-Saharan Africa, particularly in arid and semi-arid areas. Certainly, this leads to an increasingly unpredictable start and early end of the rainy season, prolonged phases of seasonal drought, and more intense rainfall. In addition, the trend seems to be towards a reduction in the general level of rainfall and an increase in occasional heavy rainfall. This means increasing difficulties for agricultural systems dependent on rainfall for irrigation. Consequently, these dynamics pose a persistent threat to food security as they result in the loss of large crops and staple foods such as maize and millet. In addition, changes in rainfall are accompanied by flooding, river overflows and flooding caused by cyclone activity in coastal areas.
In Africa, from the point of view of climate migration, we have different effects depending on the area affected. On the highlands of East Africa, floods destroy settlements and agricultural fields, often forcing farmers to abandon their cultivated areas. In the lowlands, river floods and large-scale flooding mainly affect livestock farmers operating in arid and semi-arid areas, threatening also urban workers. In southern Africa, land near large river basins and coastal areas (particularly in southeastern Africa and Madagascar) are affected by high intensity flooding, triggering temporary or permanent migration. In conclusion, it must be said that the high dependence on agriculture and livestock forces small-scale farmers and pastoral communities to diversify their sources of income. This leads to an increase in circular and seasonal migration flows within the African continent, which represents a fundamental adaptation and resilience strategy.
Climate Migration and forms of mobility within Africa
In Africa we can see rural-urban and rural-rural circular labour mobility flows that are a common reaction in all regions of the continent. In this case we speak about ‘migration as adaptation’ to climate change. Often, individuals migrate for a certain period of time in order to earn money and employ it to mitigate the difficulties of their households. However, it must be remembered that there are the so-called ‘trapped populations’, i.e. those many households that are affected by the consequences of climate change but do not have enough resources to move. In addition, there is no ‘automaticity’ to displacement because of labour exploitation, unavailability of employment. Hence, harsh living and working conditions for migrants sometimes weaken the positive potential of migration.
The most mobile communities in terms of climate migration are pastoral and semi-pastoral communities. Firstly, these are forced to move or temporarily relocate due to drought. Secondly, such displacements can take two different forms: processes of local sedentarisation or migration to urban contexts. Both of these two forms can have negative implications. For instance, communities often settle along rivers to allow livestock to drink and thus increase their vulnerability to flooding. Meanwhile, migration to urban contexts often leads newcomers to live in the slums of mega-cities. Here, in addition to the sanitation problems they may face, they may be subject to increasing violence.
Environmental and political risks
While environmental changes and their potential consequences are the key agents of climate migration, they are also linked to political, social, economic and cultural factors. In other words, the risk of climate migration is particularly serious in the presence of a generally unstable socio-political framework and prolonged armed conflicts. Letโs take an example of a fragile context with water scarcity caused by drought. In this case we are in a context with limited access to resources. First, we may have an increased likelihood of conflict over access to water between farmers and herders. Secondly, the materialisation of conflict or resource scarcity itself may lead to climate migration. Thirdly, the element of terrorism should not be overlooked. Africa is the continent that suffers most from the violence of terrorism. Often the choice to pick up a gun and serve the cause of a terrorist group is linked to a kind of law of the strongest: ‘I have the weapons, I can grab that resource’. Often the resource we are talking about is water, other times it may be the very management of a portion of territory. So, the choice of affiliation to a terrorist group is always more tied to the capacity of sustenance and nourishment.
In conclusion this article may understand that when we talk about the environment, we are also talking about society. Hence, we cannot distinguish environment between man. The fight against climate change, as well as environmental protection, are increasingly necessary to bring stability to all our societies. Finally, it must be borne in mind that each context lives with its own fragilities and that any slight change in a system (in this case we have spoken of environmental changes) can have tragic consequences.
