Development Workshop has undertaken the Environmental Risk Assessment project in a pilot district in peri-urban Luanda. This is the first project of its type in Angola, applying geographic information systems (GIS) tools in an urban / peri-urban area of Angola. The project is supported by the International Development Research Centre’s Southern Africa Regional Office and by Ranger Oil a Canadian petroleum exploration company working in Angola. The project was initiated in the second quarter of 1998 and was planned to be executed in two phases. The first phase was extended from 15 to 21 months and is complete at the present time. The second phase overlaps with the present project and integrates it into a major three year Sustainable Urban Services Project funded by the British Department for International Development (DFID) as a monitoring component. A project evaluation was undertaken in June 1999 by a GIS expert who recommended some modifications in the programme strategy and a refocusing of some of the project objectives with the aim of directing the project toward producing practical more immediate outputs. http://www.dw.angonet.org/content/urban-environmental-risk-assessment-idrc-1998-2000
