4 BACKGROUND - NAMIBIA GENERAL INFORMATION Population: 2.1 million (2011 census) Population density: 2.55 people / square kilometer (for 824,000 km 2 ) Population growth: 1.8 % / year Gross Domestic Product (GDP): 12,300 million US$ GDP per capita: 5,850 US$ GDP growth: 3.2 % / year (2006-2011) Life expectancy at birth: 62.1 years Infant mortality rate: 29.3 ‰ Literacy rate: 94.9 % (ages 15-24) HIV prevalence: 13.1 % (ages 15-49) POPULATION CONCENTRATIONS Overall and rural: northern areas Urban:central area (Windhoek) west coast (Walvis Bay, Swakopmund) OVERVIEW OF THE WATER AND SANITATION SITUATION IN NAMIBIA

5 BACKGROUND - NAMIBIA CLIMATIC CONDITIONS Geographical latitude (tropic of Capricorn passes Namibia) -> sub-tropical climate Cold Benguela current creates permanent low pressure zone in front of coast and prevents direct influx of moisture -> dry climate Seasonal movement of Inter Tropical Convergence Zone (ITCZ) creates low pressure in interior that draws in moisture from east and north -> seasonal climate annual cycle of dry and wet seasons (rainy season from October to April) OVERVIEW OF THE WATER AND SANITATION SITUATION IN NAMIBIA

7 WATER AND SANITATION VISIONS FOR NAMIBIA The Water Sector Vision is “To have achieved equitable access to sufficient, appropriate, safe, sustainable and affordable water for all Namibian users for improved quality of life.” The Sanitation Sector Vision is “A healthy environment and improved quality of life for 65% of the population having adequate sanitation services with a high level of hygiene by 2015.” OVERVIEW OF THE WATER AND SANITATION SITUATION IN NAMIBIA

8 POLICIES (1) WATER AND SANITATION POLICIES FOR NAMIBIA 2000 National Water Policy (NWP) 2008 (Revised) Water Supply and Sanitation Sector Policy (WASSSP) WATER POLICY PRINCIPLES Equitable access Cost recovery vs. affordability – tariffs and subsidization Water as economic good Community management Sustainable use – future generations Due consideration for environment and aquatic eco-systems Stakeholders involvement – basin management committees “Polluter pays” principle Integrated Water Resources Management – holistic approach Priorities for allocation (WASSSP) 1.Provision of water for domestic needs 2.Provision of water for economic activities OVERVIEW OF THE WATER AND SANITATION SITUATION IN NAMIBIA

9 POLICIES (2) GUIDING PRINCIPLES FOR SANITATION Sanitation services to communities will be provided based on the following principles and guidelines: A Water Supply, Sanitation and Hygiene (WASH) approach will be used. Community-based management (CBM) principles will be the preferred method. All households will be provided with improved sanitation facilities using the UN definition of “improved” and including hand washing facilities. Facilities should be affordable for individual households where contributions will be expected from the beneficiaries to ensure ownership and achieve long term operational and maintenance sustainability. The choice of sanitation technology by community members will be guided by the Sector Decision-Making Planning tool for rural sanitation service provision. It is expected that in most cases, dry sanitation technologies will be the likely outcome for rural community members. Collective community decisions will be required where community collection and treatment systems are proposed. OVERVIEW OF THE WATER AND SANITATION SITUATION IN NAMIBIA

29 SANITATION CHALLENGES FOR NAMIBIA CHALLENGES Need for capacity to meet MDG, Vision 2030 and NDP’s Skill gap and deficit Coordination among stakeholders DWSSC - provide overhaul coordination, regional advisory functions,inspect and monitor functions related to sanitation RWS- provide sanitation services to rural areas Fragmentation of the sanitation function Choice of technologies, codes of practice, user guides and standard designs Situation in informal settlements and rural towns Situation at schools and clinics OVERVIEW OF THE WATER AND SANITATION SITUATION IN NAMIBIA

30 CHALLENGES FOR WATER AND SANITATION (WATSAN) SERVICES IN NAMIBIA Namibia being an arid country with very limited water resources and uneven spatial distributed, faces challenges to ensure sufficient WATSAN services to all end users: Limited water for effective supply to all end users given rainfall pattern and water resources available; Rural –urban migration: high demand of WATSAN services; Income level disparity as related to cost recovery; Sanitation Technology Options not well explored, developed and adapted; Limited Human resources especially in the field of sanitation Lack of data on safe hygiene practices; Population projection vs provision of WATSAN services and facilities; Budget required for the provision of identified infrastructures gap; Lack of the monitoring system to measure WATSAN progress. OVERVIEW OF THE WATER AND SANITATION SITUATION IN NAMIBIA

31 CONCLUSION Namibia is faced with limited water resources and inadequate sanitation services. In order to meet the Millennium Development Goals, Vision 2030 and the National Development Plans, there is a need and opportunity for investment in: human resources development new and adapted technologies innovative ideas in the water and sanitation sectors.
