Some priorities for Water Management in Sub- Saharan Africa View points from FARA Alain L. ANGE Technical Adviser to FARA
What happened so far - what challenges • Food security is a burning issue • Food production could not face demand for food • Huge expected population and food demand growth • Farmers did better while farm size stagnated • Very low pace of intensification • Poor development of irrigated areas • Poor water productivity in agriculture • Climate change will exacerbate risks in farming
Food security risk index – 2011 (FAO) A sensitivity issue Africa is the largest food insecure area and has the largest population of hungry people. Food security = highest ranking component in development agenda
Food production could not match demand for food Huge changes happened in production to consumption systems in last 30 years. The cropped area doubled, production per capita dropped, imports soared The deficit of support to agriculture created a food deficit
Population and Food demand growth An Exposure For the next 30 years • Food availability per capita should increase by 30% while food import per capita should decrease; • The average production by every agricultural people should increase by 90% for maintaining food imports at present level; • Degraded land should be restored and land degradation controlled. A potential adaptive capacity
Farmers did better while farm size stagnated Small size of farm holdings is a factor of sensitiveness
Very low pace for intensification in SSA In spite of considerable development efforts, intensification of farming is coming at very low pace in SSA: • Crop productivity increased by less than 15 % in last 20 years • Livestock productivity did not changed Only 15% of farmers are using improved crop varieties Fertilizer consumption increased less than the cropped area: 6kg nutrients/ha Acreage of fully irrigated areas progressed less than total cropped areas Mechanization/ motorization progressed less than number of rural people Venues for supporting accelerated intensification of farming • Improved natural resource management /access at community level • Settling rural youth into enlarged / mechanized farming units • Improving access to water for agriculture • Developing effective production chains well connected to markets • Develop affordable agricultural credit and insurance systems • Organize farmers for resource management, mechanization, marketing
Poor development of irrigated areas - FAO In 20 years fully irrigated areas + 41% - cropped area + 47% - Population + 67% Cultivated humid lowlands ►+11% in 20 years but swallowed by irrigated schemes # = estimated projection
Climate Change will exacerbate risks in farming Climate change in Sub Saharan Africa will affect water balances: • Substantially increase temperature and evaporation of water; • Generate heat waves that may wilt crops; • Increase rainfall variability - more showers and drought spells; • Destabilize run-off regimes – more floods and low waters; • Increase the energy of gales, hurricanes and typhoons; • Generate high tides in mangrove areas and related rice fields. Climate change will also generate: • Geographical shifts of natural vegetation and animal species; • Changes in distribution of pests and diseases in agriculture; • Changes in distribution and intensity of human diseases; • Increased risks for wild fires.
Sensitivity and potentials for solutions • Poverty is the overwhelming constraint • Lack of institutional development is limiting response • Low public commitment for agriculture is hampering • Land development potentials are huge • Irrigation potentials are significant • Green and blue water available – blue water is short • Farming systems and livelihoods are diversified • Increasing energy and food prices, price volatility generate potentials and new limiting conditions as well
World distribution of poor people - 2010 Poverty = The most important component of sensitivity Source FAO Poverty reduction is key to development and a product from development With 24% of poor people, Sub Saharan Africa is the most affected continent by poverty. In relation to population growth, poor people could be 350 millions by 2030 if MDG are only partially reached.
Lack of institutional development and policy commitment Deficit of institutional development • No significant development of farmers’ unions in most countries; • Collapse of most cooperative movements • Very limited development of out-growers schemes and agreements in production chains supporting intensification Deficit of policy commitment • Dar Es Salaam Declaration in March 2003 = 10% of budget for agriculture • In 2013, 7 countries out of 53 have increased agricultural budgets • Within CAADP, in 7 years, 11 countries have developed Investment Plans • No significant change in budget for irrigation in most Investment Plans • Regulations on water access, water pricing and water quality not available Very good progress on the joint management of shared water basins
Land development potentials A D A P T I V E C A P A C I T Y Sub – Saharan Africa has huge arable land available – 800 million ha Million ha 1200 1000 800 600 400 200 0 Suitable for rain-fed crops Arable land use 1997-99 Latin America – Sub Saharan – East – South – Near East – Industrialized – Transition and Caribbean Africa Asia Asia North Africa Countries Economies 1066 1031 366 220 99 874 497 203 228 232 207 86 387 215 Extending cropped area for larger farms with adequate mechanization
Irrigation Potentials A D A P T I V E C A P A C I T Y Huge expansion potential for irrigation But potential is 1/3 of potential in South Asia for 3 fold more landmass. • Plans for irrigation development at national and watershed level; • Budget for irrigation infrastructure agreed upon; • Water-users associations promoted; • Water pricing regulated.
Farming/ livelihood systems in Africa The diversity of farming conditions and agro-biodiversity are composing a capital for adaptation to increasing markets and to climate change Extremely diverse and tightly natural resource depending farming systems/ livelihoods generate adequate local responses.
Increasing energy and food prices Energy price tripled in 10 years – Food prices increased by 80% Both trends compose a major exposure to African economies Energy cost will hit cost of irrigation Food prices are only partially reflected in producers’ price
Priorities for improved water management • Improve the productivity of green water ensuring 90% of food production so far; • Promote land use planning and water harvesting where possible • Develop irrigated rice production while sharply reducing water consumption • Rationalize traditional water use for irrigated vegetables and fruits and improve safety of waste water recycling • Promote wherever economically viable complementary irrigation, in particular for maize production • Organize the recharge of ground water bodies • Address water pricing issues to improve efficient water use • Address by regulations and enforcement water pollution from agricultural/ non agricultural activities
Conclusions Investments for irrigation have been high in few countries only; In most cases, the expansion of the cropped area has been at least as high as the expansion of irrigated areas; A large proportion of irrigation takes place in humid lowlands, taping surface and shallow ground waters through archaic systems; Irrigation is developed for rice production in modern irrigation schemes and in humid lowlands and for vegetable production in humid lowlands; Only in South Africa irrigation is largely developed for maize, soybeans and eventually canola production and for intensive fruit production. Irrigation has more impact on nutrition quality than on food security in most countries, while in the Sahel zone, it significantly contributes to the supply of grains. Increasing public and private investments for irrigation should be combined with improved water efficiency and water productivity
