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), 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 Climate Change Phenomenon is indeed a big challenge before Africa and concerted efforts must be geared towards reducing our vulnerability as a people and as a continent.
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.
Leaders across the continent must recognize a common set of interests in promoting global policies that will mitigate the human behaviours contributing to climate change and allow Africa to adapt to the effects which are already being felt #ClimateChange #Adaptation #ClimateAction #SDG13 #Sustainability #UrgentActions
