The 2006 South Africa Environmental Outlook (SAEO) document acknowledged that the “comprehensive and generally sound environmental regulatory regime is in place” and that “there has been a steady increase in the budget allocation for environmental management at both the national and provincial levels”. Yet…..: National Spatial Biodiversity Assessment (NSBA): Terrestrial systems, 34% of all 440 ecosystems are threatened Rivers - 82% of the main river signatures classified as threatened, 44% are critically endangered.

Failure is due to: • No holistic approach • No acknowledgement of the value of natural resources in development planning • Poor coordination • Increased delegation of responsibility to the local level, without the necessary capacity and support

Decrease in the rate of reduction in dam capacity Rate of decline in dam capacity measured as % of total capacity/per year. Change measured at frequency of 5 years (annual too small a period to note changes). Hydrographic survey undertaken by DWA Directorate: Spatial and Land Information Management (Reference: s.htm) Turbidity levels Decrease in annual average turbidity levels. Change in average annual turbidity levels (NTU). Change measured at 5 yearly interval (annual too short a period to account for natural variation) Measurement at inflow points to large dams using a clarity tube and measured in cm. Undertaken by DWA officials as part of daily management (this may be too onerous). Alternatively, a local resident living at the inflow is employed to take record.
