Preamble
The International Council for Science (ICSU) is a non-governmental organization
with a global membership that includes 112 National Scientific Bodies (24 of
which are from sub-Saharan Africa), 29 International Scientific Unions, and
affiliated bodies.
The long-term ICSU strategic vision is for a world where science is used for the
benefit of all, excellence in science is valued, and scientific knowledge is linked
effectively to policy-making.
The ICSU Strategic Plan 2006–2011 shows its contribution in strengthening
international science for the benefit of society to be focused on three overlapping areas:
(i)     International research collaboration – ICSU plans and coordinates
        major research programmes in key areas such as (a) global environmental
        change; (b) monitoring and observation of the Earth System; (c) collection,
        preservation, and dissemination of scientific data and information.
(ii)    Science for policy – ICSU seeks to ensure that science is integrated into
        international policy development and that relevant policies take into
        account both scientific knowledge and the needs of science. Consequently,
        ICSU represents the science community in important intergovernmental
        forums, such as the (a) 2002 (Johannesburg) World Summit on Sustainable
        Development; (b) 2003 (Geneva) and 2005 (Tunis) World Summits on the
        Information Society; (c) UN Commission on Sustainable Development, and
        (d) Earth Observation Summits.
(iii)   The universality of science – The principle of the universality of science is
        embodied in ICSU’s statutes: “The practice of science should be equitable
        and without discrimination.” Thus the primary aim of ICSU is to enhance
        the pluralism of science and reach out to all countries, by (a) ensuring that
        scientists can associate and communicate freely; (b) providing equitable
        access to data and information; (c) enabling equitable access to research
        materials and facilities; (d) building scientific capacity; and (e) bringing
        nations and disciplines together.

The ICSU Regional Office for Africa (ICSU ROA) was inaugurated on
1 September 2005 for the purpose of promoting and coordinating the activities
of the ICSU family in sub-Saharan Africa. Such an undertaking will always
consider the priorities and the specific realities of this region. In April 2006, the
ICSU Regional Committee for Africa (ICSU RCA) selected four priority areas on
which its Regional Office would focus its activities in the period 2006–2011 (and
beyond). These are: (a) sustainable energy; (b) health and human well-being;
(c) natural and human-induced hazards and disasters; and (d) global change.
To address numerous challenges that are embodied in the above priority areas,
ICSU RCA established four Scoping Groups, consisting wholly of African experts,
to prepare four science plans that would be used to implement, with great success,
the objectives of each of the four selected priority areas in sub-Saharan Africa. Terms
of Reference (ToR) for this exercise were provided to all the Scoping Groups. They
include: reviewing the current status of each priority area on the African continent;
identifying capacity-building needs; and defining deliverables to be produced to
society. Details of the ToR may be found at the end of this science plan.

Executive Summary
According to a report submitted at the 28th General Assembly of the International
Council for Science in 2005 (ICSU, 2005), the risks posed by natural and human-
induced hazards and disasters are rapidly increasing worldwide. For example, the
frequency of recorded natural disasters rose markedly during the last century, from
about 100 per decade up to 1940, to nearly 2 800 per decade during the 1990s.
Africa is the only continent whose actual share of reported disasters has increased
over the past decade (OFDA-CRED, 2002). Several factors contribute to Africa’s
high vulnerability to disasters, including the high rate of population growth, food
insecurity, high levels of poverty, inappropriate use of natural resources, and failures
of policy and institutional frameworks. Despite the hugely damaging effect that
natural and man-made disasters have on Africa’s development, little is done to
prevent them. Effective strategies to prevent hazards from becoming disasters and
to manage those disasters that do occur would make a lasting contribution to the
quality of life and sustainable livelihoods of Africans (ICSU, 2005).
The ICSU Regional Office for Africa (ICSU ROA) Science Plan on Natural and
Human-induced Hazards and Disasters proposes the establishment of research,
capacity building, and outreach programmes, aimed at reducing the risk of disasters
and at increasing resilience. The main focus of the programme is the development
of a truly regional and interdisciplinary approach to the understanding, assessment,
prediction, and mitigation of hazards and disasters. This ambitious undertaking
needs the collaborative effort of the African scientific community and policy-makers
to develop a comprehensive long-term institutional and human capacity-building
initiative that will enable science to benefit society. In particular, it will require:
(i) Building strong research and training institutions in Africa at national and
    regional levels
(ii) Facilitating the exchange of scientific information and sharing of ideas across
     borders
(iii) Strengthening the link between scientific research and policy- and decision-making
(iv) Promoting outreach activities to build resilience to disaster risks




                                                                                                                   Natural and Human-induced Hazards and Disasters in sub-Saharan Africa
(v) Tapping the knowledge base of rural and urban communities.
(vi) International cooperation in monitoring and mitigating hazards and disasters.
ICSU ROA offers the opportunity to bring together existing institutions,
appropriate partners (such as universities, research institutions, development
agencies, humanitarian assistance agencies, and non-governmental organizations),
and policy-makers to develop and build further on the activities identified in this
strategy. Details of ways in which ICSU ROA intends to achieve these objectives are
outlined in this science plan.

Africa’s preparedness for monitoring proximal volcanic
hazards and for responding to future disasters is
inadequate. Systems have been installed to monitor
seismic, thermal, and gas emissions. These need to be
complemented with satellite-based monitoring systems
such as global navigation satellite systems and radar
imagery for better mitigation strategies. Remote sensing
data (temperature, gases, geodetic, infrared) as well as
telemetered monitoring of magnetic and electric fields,
gases, and temperature are essential in so far as monitoring
of volcanoes is concerned. An ongoing project at the
Royal Museum of Central Africa in Tervuren (Belgium)
is studying and monitoring African active volcanoes
(SAMAAV), using radar interferometry to examine the
recent evolution and assess the risks associated with four
active volcanoes (Mount Nyiragongo, Mount Cameroon,
Mount Fogo, and Mount Oldoinyo Lengai). This work is
being done in collaboration with African volcanologists,             2.3 Biological Hazards

3. KEY CHALLENGES

3.1 Knowledge, Technology, and Capacity Gaps
With a few exceptions, countries in sub-Saharan Africa
lack the capacity to conduct research on natural and
human-induced hazards and disasters, or to apply the
knowledge and deploy technologies to mitigate disasters.
Compared to the developed world, sub-Saharan Africa
lacks data, information, knowledge, skills, and human
resources in this field. Furthermore, there are many
other competing claims to limited resources, and the
proportion of GDP devoted to scientific research lags far
behind that of developed regions. Governments in Africa
tend to rely on international donors rather than to build
indigenous research capacity; that is, rather than investing
in research they more often depend on donor funding
for research projects in their countries. There is therefore
                                                                    types of system could clearly be developed. During

5. STRATEGIC PARTNERS
Several organizations and institutions carry out disaster
mitigation in Africa. It is necessary to link and work
together with these bodies so that the activities of ICSU
ROA complement (not duplicate) existing activities in the
region. Some of the institutions that conduct research and
capacity building activities are listed below.

5.1 United Nations (UN)
The United Nations (UN) promotes global sustainable
development and poverty reduction through Agenda 21.
Reduction in vulnerabilities to disasters is essential to
achieve the Millennium Development Goals (MDGs).

   activities of several development partners such as the
   World Bank, SIDA/SAREC (Sweden), DFID (UK),
   and CIDA (Canada), in capacity building and needs
   assessment.

7.2 Partnerships
i. This science plan needs the support of African scientific
   institutions as well as regional and international partners
   for its successful implementation. The African Diaspora
   should be involved in the implementation of the four
   science plans of ICSU ROA. Work should be done
   by ICSU ROA to strengthen national, regional, and
   international institutional frameworks to facilitate disaster
   risk-related information management and sharing.
   Coordination of different hazard and disaster research
   initiatives at regional levels should be facilitated.
ii. Information regarding research activities (that is,
    scientific data, reports, publications) and skills
    should be disseminated through existing networks
    such as AU/NEPAD, SADC, ECOWAS, IGAD,
    CEMAC, IOC, and other pan-African structures and
    establishments.

7.3 Capacity Building and Outreach
i. Centres of excellence should be supported in efforts
   to offer specialized courses to practitioners and to
   involve postgraduate students in research projects.
                                                                    8. CONCLUSIONS

Hydro-meteorological hazards   Natural processes or phenomena of an atmospheric, hydrological, or oceanographic
                               nature, which can cause loss of life or injury, damage to property, social and economic
                               disruption, or environmental degradation.
                               Hydro-meteorological hazards include floods, debris and mud floods, tropical cyclones,
                               storm surges, thunder/hailstorms, rain and wind storms, blizzards and other severe
                               storms, drought, desertification, wildland fires, temperature extremes, sand or dust
                               storms, permafrost, and snow or ice avalanches. Hydro-meteorological hazards can be
                               single, sequential, or combined in their origin and effects.

Mitigation                     Structural and non-structural measures undertaken to limit the adverse impact of
                               natural hazards, environmental degradation, and technological hazards.

Natural hazards                Natural processes or phenomena occurring in the biosphere that can constitute a
                               damaging event.
                               Natural hazards can be classified by origin, namely: geological, hydro-meteorological,
                               or biological. Hazardous events can vary in magnitude or intensity, frequency, duration,
                               area of extent, speed of onset, spatial dispersion, and temporal spacing.

Natural disaster               An extreme event in which a natural hazard interacts with individual and community
                               exposure and vulnerabilities to trigger negative social and economic impacts on a scale
                               that is beyond the coping capacity of the affected population.

Resilience                     The capacity of a system, community, or society that is potentially exposed to hazards,
                               to adapt by resisting or changing so as to reach and maintain an acceptable level of
                               functioning and structure.




                                                                                                                                                      Natural and Human-induced Hazards and Disasters in sub-Saharan Africa
                               Resilience is determined by the extent to which the social system is capable of
                               organizing itself to increase its capacity for learning from past disasters so as to protect
                               itself better in future, and to improve its risk reduction measures.

Risk                           The probability of harmful consequences, or expected losses (deaths, injuries, damage
                               to property, threats to livelihoods, disruption of economic activity, or damage to the
                               environment) resulting from interactions between natural or human-induced hazards
                               and vulnerable conditions.
                               Conventionally, risk is expressed by the following notation:
                               Risk = Hazards × Vulnerability. Some disciplines also include the concept of exposure
                               to risk with particular reference to the physical aspects of vulnerability.
                               Beyond expressing the possibility of physical harm, it is crucial to recognize that risks
                               are inherent or can be created or exist within social systems. It is therefore important
                               to consider the social contexts in which risks occur, and the fact that people do not
                               necessarily share the same perceptions of risks and their underlying causes.
                                                                                                                              ICSU	ROA	Science	Plan




Vulnerability                  The conditions determined by physical, social, economic, and environmental factors or
                               processes that increase the susceptibility of a community to the impact of hazards.
                               For factors that increase the ability of people to cope with hazards, see the definition of
                               ‘capacity’.
