Africa most vulnerable to the effects of climate change

Africa, the world's second-largest continent, is inhabited by almost a billion people. Because of the interaction of climate change with other stresses in Africa—such as widespread poverty, population growth, acquired immunodeficiency syndrome (AIDS), the current COVID19 pandemic and overgrazing and other ecosystem damage—it is considered to be the continent most vulnerable to the effects of climate change.

Projected impacts of climate change on Africa include biodiversity loss (extinction of plant and animal species), diminished agriculture with increased hunger, increased disease, forced migration of populations (especially out of the Sahel), and more. About 70% of Africa's population lives by farming, often subsistence farming, with the poorest members of society tending to be most dependent on agriculture.

Climate change represents a major threat for the coming decades, particularly in Africa which has more climate sensitive economies than any other continent. Some regions in Africa have become drier during the last century (e.g. the Sahel) and it is projected that the continent will experience a stronger temperature increase trend than the global average.

Africa has often been identified as one of the most vulnerable regions to climate variability and change because of multiple stresses and low resilience, arising from endemic poverty, weak institutions, as well as recurrent droughts and associated complex emergencies and conflicts.

Climate-related risks have significant impacts on African populations and economies and drive large allocations to emergency resources. Under nutrition in turn undermines the resilience of vulnerable populations decreasing their ability to cope and adapt to the consequences of climate change and their ability grow economically.

Climate variability and change considerably influence shocks, trends and seasonality that observed and predicted in Sub-Saharan African countries, and that represent sources of stresses in the lives and livelihoods of exposed communities. Increased temperatures deplete land of its moisture more rapidly and can lead to regional water scarcity, salinization of agricultural lands, and to the destruction of crops. As temperatures increase, precipitation is becoming more variable over most of Africa.

For some regions, rainfall variability and unpredictability has been substantial in the past forty to fifty years,there has been an overall annual decline in rainfall observed since the end of the 1960s over Africa with some regions experiencing greater declines than others. For instance, the Sahel and Southern Africa have become drier during the twentieth century

There can be no single best approach or sets of approaches to climate change adaptation for a continent as large and diverse as Africa. However, there are a number of considerations that can help frame particular strategies and tactics. i outline here some of them.

Greater understanding of African climate and climate change – Science to understand climate in Africa is woefully lacking compared to much of the rest of the world. Simply put, substantially more investment is needed to improve our understanding African climate and its relationship to global climate processes.

More research by Africans for Africa – The impact of science investment will be greater if it is driven to a much greater extent by African researchers responsible to their own constituencies and governments than is currently the case. For example, African farmers are rightly more interested in knowledge on current rainfall variability that can inform planting decisions than multi-decadal trends in average temperature that may be more of interest to the international community.

More investment in agricultural research and new approaches to water investment – With or without additional Africa-centric climate research, the worldwide biotechnology revolution now unfolding holds tremendous promise for agricultural adaptation in Africa’s heterogeneous landscapes. Capitalizing on the opportunity will require a new prioritization of agricultural research in general and new approaches to national, international, and private research partnerships. For much of the continent, adaptation will be further facilitated by investments emphasizing improved on-farm soil and water management rather than expansion of large-scale irrigation.

Broadened approaches to food security – Better adapted seeds and agricultural practices are important to food security in Africa under climate change but so too is investment in supporting storage and transportation infrastructure as well as market access within and between African states. In many cases though, food security will only be assured if both physical and economic access to international agricultural markets is assured. This requires international regimes that support predictable and reliable trade flows as well as economic environments that support national income growth.

Urbanization and migration as adaptation strategies – Urbanization can be a source for income growth and a positive adaptive response to climate change. But only if it is driven at least as much by the pull of opportunity as the push from worsening rural conditions. National economic policy and its relation to urban growth is thus critical to rural adaption options.

Climate change is unlikely to drive migration out of the continent at rates significant to African populations. However, the political implications of these “small” numbers will still be high, giving Europe and the rest of the international community incentive to ensure an international system fair to African trade and investment.

Health systems preparedness – Strong health systems arguably provide the single best pathway for livelihood improvement with or without climate change. The global threat of climate change-related emerging infectious disease draws international attention, but it cannot be addressed without strengthening underlying national health systems.

Conflict and cooperation – Climate change will increase stress on resources as well as existing formal and informal institutions to manage them at local, national, and international levels. But climate change will also bring new impetus for cooperation. As important as it is to focus on conflict mitigation, we should not miss the opportunity to use the threats from climate change as a chance to foster new cooperation.
Finally, the situation is even further compounded by the fact that in most African countries, climate change remains a marginal issue to the pressing issue of food availability and security, political crises, poverty, natural resource management, energy access and social infrastructure. 

With more than 7.7 billion people on the planet, it’s easy to assume someone else will tackle and solve the issue of the mother earth. Yet it is an issue that affects us all. The Climate Change Phenomenon is indeed a big challenge; concerted efforts must be geared towards reducing our vulnerability as a people and as a continent.

Leaders across the continent must recognize a common set of interests in promoting global policies that will mitigate the human behaviors contributing to climate change and allow Africa to adapt to the effects which are already being felt, and as such we’re all responsible for working towards a sustainable future in which everyone is able to enjoy a good quality of life without destroying the very things we rely on to survive. #ClimateChange #Adaptation #ClimateAction #SDG13 #Sustainability #UrgentActions
