Water supply and sanitation in Sub-Saharan Africa : ウィキペディア英語版 | Water supply and sanitation in Sub-Saharan Africa Although access to water supply and sanitation in Sub-Saharan Africa has been steadily improving over the past two decades, the region still lags behind all other developing regions. Access to improved water supply has increased from 49% in 1990 to 60% in 2008, while access to improved sanitation has only risen from 28% to 31%. Sub-Saharan Africa is unlikely to meet the Millennium Development Goals of halving the share of the population without access to safe drinking water and sanitation between 1990 and 2015.〔WHO/UNESCO (2010). Progress on Sanitation and Drinking-water: 2010 Update. Geneva: WHO press.(JMP 2010 Update )〕 There are, however, large disparities among Sub-Saharan countries, and between the urban and rural areas. Usually, water is provided by utilities in urban areas and municipalities or community groups in rural areas. Sewerage is not common and wastewater treatment is even less common. Sanitation is often in the form of individual pit latrines or shared toilets. 70% of investments in water supply and sanitation in Sub-Saharan Africa are financed internally and only 30% is financed externally (2001-2005 average). Most of the internal financing is household self-finance ($2.1bn), which is primarily for on-site sanitation such as latrines. Public sector financing ($1.2bn) is almost as high as external financing (US$1.4bn). The contribution of private commercial financing has been negligible at $10 million only.〔Sudeshnha Ghosh Banerjee and Elvira Morella:(Africa's Water and Sanitation Infrastructure. Access, Affordability, and Alternatives ), World Bank, 2011, p. 217-219〕 == Access ==
