“Population
growth is increasing water demand, over exploitation of natural resources and
environmental degradation has significantly degraded the world’s freshwater
resources. In sub-Saharan Africa (SSA), the number of countries where water
demand outstrips available resources is increasing and many African countries
experience either water stress (less than 1,700 m3 per capita per annum) or
water scarcity (less than 1,000 m3 per capita per annum) or both. Moreover,
food insecurity remains endemic throughout much of Africa, with climatic
factors such as rainfall variability a major cause. If we look back in 2006, 25
African countries required food aid, largely due to recurring drought. Poverty
and food insecurity are linked to low agricultural productivity aggravated by
climate change and variability. 45 years
ago the Nobel Peace Prize Laureate Norman Borlaug stated, “Humankind in the 21st century
will need to bring about a Blue Revolution to complement the Asian Green
Revolution of the 20th century… New science and technology must lead the way.”

BACKGROUND
African smallholder farmers have no alternative
but to adapt to climate change and climate variability. This will require an
unprecedented level of political commitment, increased investments and
financial resources, and enhanced local and national capacity. Fortunately,
several practical options for adaptation exist, and these must be refined,
augmented and deployed appropriately as a matter of urgency.
Following is a list of some of these options:
Ø Intensification of food production by smallholders
through better access to improved seed, soil fertility management (eg,
fertilizer application) and reliable water supply
Ø Improved agricultural water management
(smallholder irrigation, rainwater harvesting, sustainable extraction of
groundwater and other underutilized water resources), conservation
agriculture and improved on-farm water use efficiency Shifts towards crop and
livestock types/varieties/breeds with greater drought and heat tolerance and
improved pest and disease resistance
Ø Enterprise
diversification towards higher value crops, value adding (processing),
off-farm employment, and marketing infrastructure
Ø Grain storage improvements (from household to
national levels) to ensure security of carryover stocks and access to
surpluses
Ø Climate forecasting and provision of timely advice
to governments, private sector (agro-dealers), extension services and farmers
Weather-related crop and livestock insurance

CLIMATE
CHANGE AND WATER RESOURCES
Agriculture and climate change are inextricably
linked, this was stated in one of the meeting after the horn Africa food
crisis that “Agriculture is part of the climate change problem, contributing
about 13.5% of annual greenhouse gas emissions (with forestry contributing an
additional 19%), compared with 13.1% from transportation. Agriculture is,
however, also part of the solution, offering promising opportunities for
mitigating emissions through carbon sequestration, soil and land use
management, and biomass production. Climate change threatens agricultural
production through higher and more variable temperatures, changes in
precipitation patterns and increased occurrences of extreme events like
droughts and floods”. The challenges of water resources development in SSA
will be aggravated by ensuing climate change, with serious implications on
socio-economic development. The intergovernmental Panel on Climate Change in
2007 noted that “these challenges include population pressure, problems
associated with land use such as erosion/siltation and possible ecological
consequences of land use change on the hydrological cycle. Climate change –
especially changes in climate variability through droughts and flooding –
will make addressing these problems more complex. The greatest impact will
continue to be felt by the poor, who have the most limited access to water
resources”. In the savanna regions, the incidence of seasonal flow cessation
may be on the increase, as shown by some streams in Zimbabwe. Southern Africa
has experienced more recurrent drought and flood episodes in recent times.
Drought periods now translate into periods of critical water shortages for
industrial and urban domestic supplies. The frequent droughts and floods in
most parts of SSA – leading to severe food shortages, food insecurity, water
scarcity, hunger/famine and acute shortage of hydro power – signify the
region’s vulnerability to climate change. Reduced hydro power also affects
energy supply for pumping water. There is a general consensus that the
African continent is particularly susceptible to the onset of climate change.
A variety of factors exacerbate susceptibility to the effects of climate
variability but, in focusing on strictly physical elements, the range of
ecosystems present on the continent poses particular challenges in developing
mitigation and adaptation mechanisms.

GENDER
PERCEPTIVE VS CLIMATE CHANGE
Emerging evidence shows that women and girls will
experience even greater inequality through the impacts of climate change. It
is evident that women suffer disproportionately in nearly all disasters. In
2011 in the Horn of Africa according YOUNG research “disasters shortened
women’s life expectancy significantly more than men’s but encouragingly, this
association was reduced where women’s status was more equal. Many women are
made vulnerable by their reduced access to sources of emergency information,
as well as their lack of decision-making power in disaster prevention and
preparedness programs; they are also often excluded from disaster recovery
operations and from planning at the national level”. I realized that “the
unequal impact on women is not only evident in major disaster events – it
also affects everyday life and opportunities, since in many low income
countries, women already work more hours each day than men. Additionally, in
Africa, women are more involved in agriculture than men – an estimated 80% of
smallholder farmers are women”. It’s estimated that women produce 60-80% of
food grown in the developing world – often small-scale crops critical to
sustenance. In SSA, women are responsible for 65% of farming activity in the
smallholder irrigation sector In addition; women and girls are responsible
for collecting and carrying water, among many other domestic activities. I
think “as communities cope with the effects of changes in climate, demands on
women’s time and workloads are likely to increase. To compensate for
increased demands on their time, poor families may pull girls out of school”.
The added stresses incurred by a changing climate compound the many risks
already faced by women in developing countries. Consideration and integration
of gender issues is therefore important in any assessment of how smallholder
water resources management relates to climate change in Africa. The equal
inclusion of men and women in all aspects of water resources management is
imperative. Gender mainstreaming must focus on a holistic approach to ensure
sustainability of climate change adaptation strategies and programs in
Africa. Gender-sensitive water governance should address the institutions,
policies, legal frameworks and technologies that perpetuate gender inequalities.
A gender approach in governance should be an integral part of setting up
broader governance structures and mechanisms. This means promoting the
involvement of both women and men in consultation and decision making from
the community level to the highest management levels. Gender-focused
approaches in water governance depend on the skills, knowledge and commitment
of staff involved in implementation and management.

POLICY
RECOMMENDATIONS
The predicted impacts of climate change must be
introduced into development planning, including land-use planning, natural
resources management, infrastructure design and measures to reduce
vulnerability in disaster reduction strategies, the array of adaptation options
is very large, ranging from purely technological measures to managerial
adaptation and policy reform. For developing countries, availability of
resources and adaptive capacity building are particularly important. Based on
anticipated climate change and impacts on water resources in Africa, the
intergovernmental Panel on Climate Change identified four necessary adaptive
strategies.
Ø Adaptive measures. Measures should be adopted that
would enhance flexibility, resulting in net benefits in water resources
(irrigation and water reuse, aquifer and groundwater management,
desalinization), agriculture (crop changes, technology, irrigation,
husbandry), and forestry (regeneration of local species, energy-efficient
cook stoves, sustainable community management).
Ø Risk sharing. A risk-sharing approach between
countries will strengthen adaptation strategies, including disaster
management, risk communication, emergency evacuation, and cooperative water
resources management.
Ø Enhancement of adaptive capacity. Local
empowerment is essential in decision-making in order to incorporate climate
adaptation within broader sustainable development strategies. Most countries
in Africa are particularly vulnerable to climate change because of limited
adaptive capacity as a result of widespread poverty, recurrent droughts,
inequitable land distribution and dependence on rain fed agriculture.
Ø Diversification. To minimize sensitivity to
climate change, African economies should be more diversified, and
agricultural technology should optimize water usage through efficient irrigation
and crop development.
