Contemporary conversations about climate change and development in Africa suffer from a scale problem. Generally speaking, these conversations go one of two ways. Some talk about “African climate change”, speaking in sweeping terms about such impacts as lost agricultural production or increased disease burden. Others focus on potential local impacts, sometimes scaling to national impacts. Neither of these foci facilitates thinking about climate change as an integration issue for Africa.

Others focus on potential local impacts, sometimes scaling to national impacts. Neither of these foci facilitates thinking about climate change as an integration issue for Africa.
Discussions of “African climate change” fail to characterize
the different ways in which the climate is expected to change in different
parts of the continent, and therefore the different challenges and
opportunities that will arise in different places. Nationally or locally
focused discussions, while bringing nuance to the African climate change
conversation, tend not to illuminate the differences between the places under
consideration and other places in the country or region. In both cases, these
conversations miss the regional scale, where opportunities for integration
abound.
Take, for example, food security and agricultural
development. In a given year and a given region of Africa, there are areas
producing food surpluses, and other areas experiencing food deficits. A
variable and changing climate often plays a role in both outcomes. Critically,
however, weather and climate do not cause food insecurity. Weather and climate
can serve as a trigger for food insecurity, but an extensive literature has demonstrated
that markets and institutions have much more do with food outcomes than the
weather. Integration provides an opportunity to address both, by building the
infrastructure, food production capacity, and international agreements
necessary to allow for the movement of food from sites of food surplus to sites
of food deficit in the course of normal trade, instead of the exigency of
emergency.
If integration is a key means of addressing this climate
change challenge, we must also recognize that climate change poses a critical
challenge to integration itself. While building better infrastructure and
agreements are necessary to address the current and future challenges presented
by climate-related food insecurity, the future trajectories of climate change will
also shape where roads will be most useful, where food production investments
will yield the greatest returns, and between whom to create agreements. We
should not presume that current subregions of food surplus and deficit will
play the same roles over the next two or three decades. In most parts of
Africa, when and were the rain falls will change and temperatures will shift
unevenly, even within subregions. What farmers do to address these challenges
will vary between subregions, countries, and even communities as the strength
of extension services, the quality and accessibility of inputs, and the
idiosyncrasies of local innovation generate differentiated indigenous
adaptation pathways. In short, the future is one of changes that will be
complex and difficult to predict.
When we connect climate change conversations that currently
focus on the poles of the continental or subnational/national scale to more
regional thinking, the information gaps that impede integration efforts become
clear. We have only parts of the information that we need to plan integrated
responses to climate change impacts. Most of this information exists in the
form of climate models whose reliability decreases the further we move into the
future, and whose spatial resolution is often too coarse to fully inform
planning decisions. Policy studies tend to provide little predictive resolution
with regard to what policies and budgets will exist in the future. And we know
next to nothing about local community- and household-level livelihoods
decision-making that will inform the sorts of innovations and adaptation
pathways that emerge in different places as the changing climate stresses
existing activities.
All we have the outlines of a changing future in Africa tied
to climate change. This outline provides hints of what is to come, without any
of the details needed to connect these hints into a reliable narrative of
response. The missing details point us to the steps we need to take if we are
to respond effectively.
- There needs to be a concerted
effort to create a transparent policy environment in which the potential
impacts of climate change might be used as a lever to bring parties to the
table in productive discussions about trade. While this will not
resolve all of the uncertainties about the policy future with regard to
climate change, it will create an environment in which the impacts of
climate change, whatever they might be, can be productively addressed.
- More
serious attention needs to be paid to existing climate science in policy
discussions. While the policymaker need not be an expert in climate
science, the long-range future of nearly every development sector will be
impacted by a changing climate. Policymakers need to understand the scope
and nature of these impacts, as well as the uncertainties associated with
the science.
- A
significant investment in basic research on indigenous livelihoods and
adaptation decision-making is needed. The broad panel surveys of
livelihoods activities that exist for much of the continent are often very
unreliable. Further, the information they contain merely catalogues what
people are doing, not why. Without a serious push to better understand why
people do what they do, we cannot productively imagine what they will be
doing under possible climate futures.
Getting the scale of discussion right is the first step in
building adaptation strategies that can harness opportunities beyond the
national, without resorting to the near-meaningless generalities of the
continental. If African responses to climate change impacts are to be more than
mere efforts to hang on to current activities, as opposed to efforts to harness
the opportunities created by climate change, integration will be a key
component of this effort.
