Introduction to the Session 6 - Theme 4 – on “Water Resources Management and Governance”
2
Integrated Water Resources Management implies three main elements: The Concept of Integrated Water Resources Management Economic Equity Environmental Sustainability Management Instruments Assessment Information Allocation Instruments Enabling Environment Policies Legislation Institutional Framework Central - Local River Basin Public - Private Balance “water for livelihood” and “water as a resource”
3
IWRM: A cross-sectoral approach Water for people Water for food Water for nature Water for other uses Cross-sectoral integration Enabling environment Institutions Management tools
4
Implementation frameworks For IWRM Framework for water governance Framework for water infrastructure development Framework for water and sanitation service delivery Framework for water efficiency improvements
5
Addressing vulnerability: “Vulnerability of Water Resources to Environmental Change in Africa” Aim: Aim: Managing vulnerability risks at transboundary, national and local, river/lake/groundwater basin and catchment levels Action: Action: Assessment of effects of environmental and human driven changes on water resources Impact: Impact: Management and long-term conservation of ecosystems – Strategy and policy development - Awareness creation… Where are water resources most at risk? Africa’s high dependence on natural resources makes people vulnerable to environmental change Where are water resources most at risk? Background
6
We don‘t know yet Vulnerability is multifaceted: Climate variability; Pollution; Population growth; Competition over water; Data availability and quality; Knowledge gaps… Why we need vulnerability assessments People already live on the threshold Ecosystems are at high risk For whom it is important Government, Policy and decision-makers and affected communities... Where are water resources most at risk?
7
The river, lake, groundwater basin approach Basin approach supposes: Balances resource protection and utilization Considers all components hydrological cycle Incorporates IWRM principles (equity / efficiency / sustainability) Seeks to maintain a balance between competing pressures Resource integrity in the long-term Social upliftment and advancement Economic growth and use of environmental resources

Physiography Climate Extreme events and impacts Ecosystems Impacts of land use changes Surface Water Distribution, quantity and quality Storage and supply infrastructure Groundwater Socio-Economy Demography Population growth and urbanisation Water related diseases and HIV/Aids Access to safe water and sanitation services Water use Water related conflicts Economy Management Legislation Governance of water resources Implementation and adaptive capacity (finances, human res.) Institutional Knowledge Data availability and quality Knowledge gaps (climate change, water pollution, water res.) Key issues, adaptation and mitigation
11
Northern Africa Nile River Basin Nubian Groundwater Basin
12
Nile River and Nubian Groundwater Basins Vulnerable: high aridity, low water availability, high poverty and moderate management
13
Western Africa Senegal and Niger River Basins
14
High aridity, low water availability, water scarcity Vulnerable: high poverty, delayed sector reform, very low adaptive capacity
15
Southern Africa Zambezi and Orange River Basins
16
High aridity, low water availability, water scarcity Vulnerable: inadequate access, management and poverty
17
Key Issues – 1 Physiography Climate change & variability Increased frequency of droughts and floods Small reduction in Rainfall Large reduction in river flow …Persistent drought in the Sahel since 1970s… (includes largest part of Niger River Basin) Ecosystems Biodiversity Desertification Wetland degradation …Deteriorating ecosystem integrity Lake Victoria Basin… Surface Water Limited resources, unevenly distributed & over-exploited …Nubian Sst Aquifer Basin: non-renewable water resource… Pollution …Industrial & municipal effluent loading Orange River Basin… Groundwater Key Issues
18
Key Issues – 2 Socio-Economy Demography High population growth rate in urban areas Water related diseases and HIV/Aids …Southern Africa has the highest incidence of HIV/AIDS… Poor water and sanitation coverage and service delivery …Inadequate access to clean water and sanitation in peri-urban and rural areas… Agriculture most important economic activity and biggest water consumer (80%) Competition for water …High competition between irrigators and hydropower in Rufiji Basin… Economy
19
Key Issues – 3 Management Legislation Water legislation Inadequate institutional strength and capacity..Establishment of Co-operative Frameworks for Managing Shared Waters in the context of IWRM.. Institutional Knowledge Data access, sharing, reliability and standardisation Monitoring Knowledge Gaps - Insufficient insight into climate change and variability - Water pollution inadequately addressed - Groundwater recharge largely unknown - Environmental Flow Requirements largely unknown Water Scarcity Water Scarcity Water resources are at risk and water stress is expected to increase…
20
Adaptation and Mitigation Options Institutional & Legislative Framework Water Sector Reforms Managing (shared) waters and ecosystems Communities' responses to water stress Capacity Building Capacity enhancement programmes Data & Monitoring Data rescue Standardized assessments Monitoring for improved early warning systems and effective water management Technologies Surface / groundwater storage and use Rainwater harvesting Improvement urban water supply Investment in wastewater treatment Improvements in agricultural techniques Water Trade
