Climate change wreaks havoc in Southern Africa

Climate change is a worldwide phenomenon that has expressed its disruptive impact in Southern Africa with exceptional vigor. As temperatures rise, weather patterns shift, and natural ecosystems transform, the repercussions for the nations that call this diverse and vibrant region home have been disastrous.

 

Climate change’s havoc in Southern Africa has become an urgent worry that requires both local and international attention, from prolonged droughts that cripple agriculture and water supplies to increasingly frequent and severe storms that destroy communities.

 

The region is the continent’s southernmost region, encompassing Angola, Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Zambia, and Zimbabwe. Seasonal climates in Southern Africa range from desert to semiarid and temperate to tropical. Seasonality is a key regulator of river flows and control of plant development.

 

Droughts are a typical occurrence across much of Southern Africa. Savanna woodlands which are known as miombo forests are found in the north, followed by several dry woodlands to the south, arid and semiarid grassland, scrubland, and bushland in the Namib and Kalahari deserts, and their surroundings and Mediterranean vegetation along the southern coast. As a result of climate change, the seasons have become more volatile.

 

Storms caused by climate change have devastated Southern Africa. Data from the World Weather Attribution demonstrates that severe rains are becoming more common, demolishing homes, creating power outages, and increasingly interfering with people’s daily lives, pushing them into extreme poverty.

 

This is not an instance of natural justice. According to the researchers, the study reveals that extreme weather in Southern Africa is brought on by human-induced global warming. In six weeks, the region was hit by three cyclones and two tropical storms.

 

How climate change is impacting Southern Africa

 

Southern Africa is a terrific site for tourists because of its outstanding biodiversity, but the countries are increasingly threatened by climate change, land use, and other factors.

Climate change is a severe threat to global biodiversity at all levels; population growth, urbanization, and a lack of other sources of income place further strain on natural resources and impede conservation efforts. These pressures have resulted in environmental deterioration in several regions of Southern Africa, increasing their sensitivity to climate change, the impact is in different areas such as:

 

Water: Most of the renewable water in Southern Africa is found in shared transboundary river basins. Water is already scarce in Botswana, Namibia, and South Africa’s south-western areas. Drier regions are predicted to expand with climate change scenarios with decreasing precipitation, eventually including nations such as Zambia, Zimbabwe, and southern Angola.

 

Extreme dry episodes in the Kalahari could cause the Kalahari Desert to expand eastward and northward. Even places that are not presently experiencing water shortage are at risk of experiencing per capita water scarcity as future climate, population, and development pressures increase demand for diminishing freshwater supplies. Water scarcity endangers human and political security on multiple levels. Water-related human security challenges present themselves as disputes at the individual, family, intra- and inter-village levels.

 

Household, intra-, and inter-village conflicts occur in Southern Africa because water resources are insufficient to support basic sanitation, drinking, food production, and livestock watering requirements. Human uses compete with cattle uses, and political tensions may be exacerbated by water scarcity. Instances like when Zimbabwe’s Matabeleland region is viewed as a war flash point if water constraint is not addressed.

 

Health: Extreme weather has a well-known influence on vulnerable people. Extreme changes in water supply and poor water quality are linked to human health in Southern Africa via several direct and indirect pathways. Water therefore represents the most important link between climate change and health. The risk of unanticipated disease outbreaks and disruptive illnesses is linked to water and climate.

 

Poverty-driven rural-to-urban migration results in congested peri-urban communities with inadequate water supplies, sewage systems, roads, and health facilities, as well as being highly susceptible to water-borne disease and a lack of readiness for climate shocks like floods.

 

Flooding exacerbates poor sanitation conditions, leading to epidemics of diseases such as cholera. Exposure to climate-related disasters is thus an important climate-health relationship. Temperature and humidity are also connected to a surge in the occurrence of tropical diseases like malaria, which some areas are experiencing. Malnutrition and food security-related diseases are frequent in Southern Africa’s rural communities, and forecasted climate change situations are likely to exacerbate this. Droughts, for instance, have already culminated in low crop yields.

 

Food insecurity: Climate change is hurting food security in Southern Africa, in addition to growing water scarcity. Even in the absence of climate change, the region’s agriculture is failing to satisfy its residents’ food security demands, and per capita food output has stalled, with some countries suffering decreased food production.

 

Climate change will add to the pressures on an already stressed industry. It will have an impact on most of the millions of people who rely on rain-fed agriculture and ecosystems for a living. While food production is dependent on rural land, there is a history of migration from rural to urban areas.

 

As a result, while rising populations rely on food purchases, income production through jobs suffers as economic growth stagnates. Food security and human health have been impacted by rising food prices over the previous decade, and the threat of climate change and rising food costs paints a grim picture of food security in the area.

 

Climate change’s catastrophic manifestations in Southern Africa serve as a sharp reminder of the urgent need for global action. The region’s vulnerability to extreme weather events, lengthy droughts, and shifting ecosystems has underlined our world’s interconnection and the far-reaching implications of environmental deterioration. As we see the devastation wreaked on communities, ecosystems, and economies, it becomes clear that addressing climate change is not only a moral imperative, but also a strategic need.
