Food and Water Security Post-2015: The Role of Experts, Private Sector and Policy Makers
- 1. ….FOOD AND WATER SECURITY POST 2015- THE ROLE OF EXPERTS, PRIVATE SECTOR ND POLICY MAKERS…. Some slides by Prof. Mati

- 4. Africa is Endowed with Abundant Water Resources • Africa has about 4,000 cu km of freshwater. • There are 17 rivers with catchments areas >100 000 km2 • There are 160 lakes >27 km2, • Mean annual rainfall 670 mm/yr • Highly variable rainfall ranging <100 mm in deserts to over 2,000 mm in rainforests & highlands • Huge hydropower potential of about 1,750 TWh (12% of the global capacity) • Vast ground water resources • The continent is surrounded by three oceans (vast marine water)
- 5. • About 65% of Africa’s land area comprises drylands (annual rainfall 100-800 mm) • Rainfall is erratic, droughts, floods & high runoff losses • High evaporation losses (up to x 10 annual rainfall) • Poorly distributed water resources (rivers, lakes) • High runoff losses (over 50% of rainfall is lost) • Renewable water resources constitute only about 20% of total rainfall. But Africa Suffers from Extensive Water Scarcity

- 8. INCREASING WATER DEMAND • Africa’s average population growth rate between 2005 and 2010 was 2.3%, the highest in the world (UNFPA 2009). • The growth in water demand is not matched by a corresponding development of water resources • Africa has the world’s lowest per capita water withdrawal at about 170 m3, due not only to poor water resource availability but also underdeveloped water infrastructure and inefficient water management. • Less than 25% of Africa’s average annual river runoff is being utilized for human developmental activities (Couet and Maurer 2009) • Total annual withdrawals for the three major water-use sectors of agriculture, municipalities and industries is only 5.5% of internal renewable resources. • Agriculture is mostly rain-fed and less than 10% of the continent’s cultivated land of 185 million ha or 6% of the total land area is irrigated.

- 19. Issues to tackle in addressing Sustainable Water Use Declining water availability/ increasing demand Inefficient technologies and practices Policy enforcement disconnect Declining arable land area and soil health How to bring to scale inputs of science in SWU Capacity of SWU sector across the value chain SWU should not get lost in the “missing middle” Smallholder agriculture in transition Climate change, floods and droughts
- 20. Making Use of Partnerships Typologies of Partnerships • Official partnerships set up by a number of organisations. • More bottom-up partnerships initiated by non-profit organisations or groups. • Short-term alliances created around a particular project or programme. • Informal partnerships to support ongoing delivery of services and aims. • Other forms of collaboration to share information and offer mutual support that may be better seen as networks Research Partners – for synergies, economies of scale and cross-learning. Financing and investment partners - to leverage finances through collaborative activities, e.g. PPP, matching funds Implementation Partners- at national, region & international levels e.g. Govts, NGOs Policy partners – to facilitate policies, legal & institutional support
- 21. Water Dev issues of focus (as identified by AMCOW) – Closing the gap in attaining the MDGs and ‘unserved’ communities – Integrating water as key to poverty reduction and socio-economic development – Expanding Africa’s water infrastructure assets to achieve this. – Fostering transboundary cooperation – Mobilising the financial resources needed to build the infrastructure – Build and strengthen institutional and technical capacity and skills; the water data base, information knowledge and monitoring capacity – Fostering partnership with stakeholders for full participation – Closing the implementation gap between Africa’s agenda and the policies of Development Partners – Tackling the climate change challenges and building resilient adaptation systems The Targets for Africa are aimed at:
