This article explores policy options for water-stressed states in the Middle East and Southern Africa, considering stress versus absolute scarcity, resource constraints, implications for cooperation or conflict, and the progress in Southern Africa.

Some thoughts on Policy options in water stressed states :Middle East vs Southern Africa Mike Muller Director General Department of Water Affairsand Forestry
Stress versus absolute scarcity Resource constraints - natural or financial Implications for cooperation or conflict Southern African progress - any implications for Middle East ? Policy options in water stressed states : Department of Water Affairsand Forestry

The Southern African challenge:Less water “shortage” than natural variability and financial constraintsMiddle East – some face absolute scarcity Department of Water Affairsand Forestry

Southern Africa - not water shortage The “shortage” is mainly of the financial and related resources to manage the water that is available, to capture and store it, transport it to where it is required for use and then to use it efficiently to maximise its potential social and economic contributions.

Extreme Variability : Africa’s Burden Kenya: Annual Rainfall Variation about the Average 160% 140% 120% 100% 80% 60% 1956 1958 1960 1962 1964 1966 1968 1970 1972 1974 1976 1978 1980 Department of Water Affairsand Forestry
Natural legacy Extreme climatic variability (+/- 35%), recurrent floods and droughts n Department of Water Affairsand Forestry
Key Southern African Issues • Resource greatly under- developed & exploited • Variability needs storage and imposes costs • (Aggravated by impact of climate change) • Poor Countries lack public funding capacity & incomes to support higher levels of activity • Lumpy, long investments, aggravate situation • Global trade & investment environment critical Department of Water Affairsand Forestry

Regional Cooperation • Approaches to mitigate stress: • store the water, • transport it to where it is needed • use it efficiently • focus on areas of “water advantage” • All cost money • Need for integrated approach • (rivers know no boundaries) • Cooperation may offer efficiencies Department of Water Affairsand Forestry
Regional Cooperation Water’s co-operative advantage: Unlike minerals (and related energy) resources water is a renewable resource – If you mess it up one year, you get a chance to start again the next. Provides “learning context” for cooperation. Department of Water Affairsand Forestry
Regional Cooperation Non-cooperation ? reduced early warning capacity reduced water availability reduced production flexibility increased risk (perceived & real) …….dispute & even conflict Department of Water Affairsand Forestry
Regional Cooperation Cooperation/integration enhanced monitoring /early warning diversified water storage & economic production (power, food, etc) mobility of labor and commodities diversification of political & economic risk Department of Water Affairsand Forestry

Southern African Progress • Some examples • Mozambique (Zambesi): • power generation and flood control • Lesotho (Highlands): • income generation and supply security • Swaziland/Mozambique (Komati) • supply security, cost effective supply and improved management efficiencies Department of Water Affairsand Forestry
Southern African Progress • Implications for Mid-East ? • Geopolitics are different (regional growth and development is a SA priority) • Southern African scarcity not comparable (Palestine/Israel/Lebanon) • Some opportunities are present (notably Iraq/Syria/Turkey) • Could water be a vehicle for cooperation ?

Policy Options Department of Water Affairsand Forestry
Water and Regional Integration • Climate variability: manage through mobility of production & trade regional integration • International waters: enhance regional security through joint management regional integration Department of Water Affairsand Forestry
New burdens : climate variability (change?)index of rainfall in Sahel 1941-1990 Departure from standard deviation; Climate Prediction Center 1991 Department of Water Affairsand Forestry
Drought…. Southern Africa drought (1991/2) • 20 million affected; $2b relief Zimbabwe drought (1991/2) • 45% decline in agricultural production • 11% decline in GDP • 62% decline in stock market • 9% decline in manufacturing output • 15% reduction in power generation Department of Water Affairsand Forestry
The case of Kenya (Mogacha, Gichere, Davis, Hirji) • Economic shock: 97/98 El Nino flood; 99/00 drought: $4b (45% of GDP); • Direct recurring annual cost: catchment degradation/deteriorating water quality $120m/a • BUT: indirect costs of perceived risk of variability?? Department of Water Affairsand Forestry
Economic impacts of variability • Massive shock of extreme events • Agrarian incomes amplified through economy • Investment disincentives / risk averse behavior • Economies trapped in low level equilibrium • Pervasive impacts in all years Department of Water Affairsand Forestry
International rivers: economic impacts? • Tensions -> economic fragmentation / limited integration • Perverse policy responses (eg self sufficiency) • Diversion: economic development -> security? Department of Water Affairsand Forestry
Climate variability impacts & some solutions Factors exacerbating climate variability impacts • International rivers without cooperation • Lack of information >> no early warning • Lack of control options>>flexible storage • Expanding extensive agriculture (Africa’s growth strategy…) • Watershed degradation>>flashy rivers>>more floods/droughts Mitigating the Risk of Rainfall Variability • Storage Investments • Structural: reservoirs, groundwater recharge • Non-structural: watershed management, wetlands conservation • Policies (ag. intensification, zoning, pricing, insurance...) • International cooperation Department of Water Affairsand Forestry
Southern Africa Regional Challenge • If you are poor, you have to be clever • Cooperation can pay dividends through added efficiencies • “go it alone” policies will be penalised Department of Water Affairsand Forestry
