New research compiled for the Africa Water Atlas by the United Nations Environment Programme (UNEP) showed that only five countries in Africa are expected to attain the Millennium Development Goals (MDGs) target of reducing by half the proportion of the population without sustainable access to basic sanitation by 2015. It showed that at present, only 26 of the continent's 53 countries are on track to attain the water-provision target.
The Atlas uses hundreds of 'before and after' shots, detailed new maps and satellite images from 53 countries to show the problems facing Africa's water supplies, such as the drying of Lake Chad and the erosion of the Nile Delta, as well as new, successful methods of conserving water. This included how rainwater conservation is improving food security in drought-prone regions.
Prepared in cooperation with the African Union, European Union, US Department of State and United States Geological Survey, the 326-page atlas gathers information about the role of water in Africa's economies and development, health, food security, transboundary cooperation, capacity building and environmental change in one comprehensive and accessible volume.
Achim Steiner, UN Under-Secretary-General and UNEP executive director, said: "The dramatic changes sweeping Africa linked with both positive and negative management of this continent's vital water resources is graphically brought home in this Atlas.
"From the dams triggering erosion on the Nile Delta to pollution in the Niger River Basin, the way infrastructure development or uncontrolled oil spills are impacting the lives and livelihoods of people are all brought into sharp relief," he said.

In BriefWastewater treatment plant in Saudi Arabia reaches completionA new 2,000 m³/day (approximately 0.5 million gallons per day) facility has been commissioned in Rabigh, Saudi Arabia and will serve the residents of the large community that supports the regional Petro-Rabigh oil refinery.
Parkson provided initial design responsibilities for the project which includes grit removal and screening, balancing tanks, denitrification, fine-bubble aeration, submerged hollow-fiber MBRs, and a permeate wet well.
The plant, with complete built-in redundancy, includes extensive process controls and 100% monitoring capabilities. Parkson will operate the facility under a six month operation and maintenance contract, with the possibility of longer-term operational responsibilities.
According to the firm, at least 70% of the wastewater flow will be used for landscaping irrigation throughout the residential community. It is hoped the plant will set the standard for water efficiency in oil production across the Middle East.
The MBR plant will need to remove 96-99% of the incoming BOD and be able to operate in an environment which can reach 50° C (122° F).
Nigerian-Switzerland Water PartnershipThe Federal Ministry of Water and Federal Government of Nigeria have signed an agreement to install several autonomous water filtration units, powered by solar and wind power, from Trunz Water Systems of Switzerland. It is hoped that the units will help to deal with the problem of contaminated water supplies and waterborne diseases. The company said the systems don't require chemicals or diesel for generators and are designed to provide a "green and sustainable solution for remote communities or pure, clean drinking water".
