This map, published with the original MacDonald, et.al., study, depicts potential ground water resources on the African continent. Areas in blue represent the most water-abundant areas.
Not long ago, the BBC reported (here)
on vast reservoirs of ground water resources underlying the African
continent and the critical use that this water could have for
populations now and in the future. While the so-called “discovery” of
this water wealth may be questionable (see WaterWired’s Michael Campana
explaining what we already knew here),
the resurgence in interest in fresh water for Africa is a critical
development in itself. The MacDonald, et.al., study that started this
latest brouhaha can be found here.
Africa remains one of the poorest regions in the world in terms of
access to fresh water resources. A recent report by UNICEF and the World
Health Organization (here)
indicates that approximately 300 million people in sub-Saharan Africa
are without access to safe and clean drinking water. Of the countries
reported to have less than fifty-percent coverage in water supply,
almost all are located in sub-Saharan Africa. Additionally, only some
thirty-percent of the population in sub-Saharan Africa is blessed with
improved sanitation coverage, making the region one of the most
underserved in the world.
In the year 2000, the world’s major leaders came together at the
United Nations Headquarters in New York to adopt the United Nations
Millennium Declaration (here).
The Declaration was intended to create a global partnership aimed at
reducing extreme poverty throughout the world. Targets, known as the
Millennium Development Goals, were set to achieve the Declaration’s aim,
with a deadline for the year 2015 (see here).
In sub-Saharan Africa, where some of the worst poverty and water
scarcity conditions exist, only nineteen of the fifty existing countries
are expected to meet the Goals’ drinking water targets by the year
2015.
This UNECA chart compares water availability for countries
throughout Africa from 1990 to 2025. By 2025, all countries in the
region are expected to be in a state of water vulnerability, with most
being in states of water stress or water scarcity.
Given the troubled state of Africa’s water circumstances, a renewed
focus on the significant sources of ground water underlying much of the
continent comes at a very important time. In addition to concentrating
attention on a dire situation, it provides opportunities for the region
and the global community to explore means of overcoming the water
challenges facing Africa and for sustainably developing and managing
these underground resources. One of these opportunities is directly tied
to the fact that many of Africa’s aquifers are transboundary,
underlying two or more nations. The Nubian Sandstone Aquifer System, for
example, is situated below Chad, Egypt, Libya, and Sudan; the
Iullemeden Aquifer System underlays Mali, Niger and Nigeria; and the
Baggara Basin aquifer is underneath Central African Republic, Sudan, and
South Sudan, including the parched and war-ravaged Darfur region.
As the availability of fresh water decreases across the continent,
competition and tensions over transboundary resources are likely to
rise. To date, however, none of the transboundary aquifer countries in
Africa have entered into an aquifer sharing or management arrangement.
The only transboundary aquifer-related arrangements on the continent are
two rudimentary consultative and data-sharing agreements formulated for
the Nubian Sandstone and Northwestern Sahara aquifers in North Africa
(you can find the texts for these arrangements here and here).
More than seventy aquifers and aquifer systems in Africa
have been identified as “transboundary” by the United Nations’
International Groundwater Resources Assessment Center. IGRAC’s
Transboundary Aquifers of the World 2012 map is available here.
Given the levels of water stress and scarcity that African countries
are currently experiencing, and which are predicted to increase rapidly,
the need for action is immediate. Although ground water resources in
Africa are vast and provide great opportunities for overcoming the
continent’s water scarcity problems, the lack of information, technical
capacity, adequate funding, and cooperation prevents many African
nations from overcoming the water challenges facing them. Accordingly,
it is crucial that all of Africa – from the national level to the most
local community – develop programs that will expand the exploration of
water resources, push for data-generation and sharing, and encourage
cross-border cooperative and sustainable management initiatives. It is
also critical that the United Nations, as well as the developed world,
offer their assistance for this worthwhile effort.
The mere discovery of a new source of fresh water underlying one of
another nation will not ensure it a future free of water scarcity. Only
by cooperating and carefully and sustainably managing such resources
will Africa’s nations be able to secure the much needed water for its
communities and environment.
