Policy Implementation for Water Resources Protection: Assessing Spatio-Temporal Trends of Results from Process-Based Outcomes of Resource-Directed Measures Projects in South Africa

Governments are continuously developing strategies for policy implementation toward water resource protection. However, little is known about the practical application of such plans to test their effectiveness in policy practice. This study focused on resource-directed measures (RDMs) in South Africa to assess progress made on policy implementation for water resource protection. The study included document surveys and content analysis of the publicly available reports and documents sourced from state departments and government websites. The findings of the study indicated that water resource-directed measures are used as policy implementation strategies for water resource protection in the country. Furthermore, the study revealed that significant progress has been made in this regard, when a multi-sectorial policy implementation practice approach through public-private partnerships ensured that 69% of the catchments have process-based RDM projects completed, while 18% are in progress, and only 13% are outstanding. In addition, it was found that water resource classes (WRC), numerical limits and ecological conditions for water resource reserve, and numerical limits and narrative statements for resource quality objectives (RQOs) are intermediate outputs originating from RDMs projects. The study recommends that outputs derived from process-based policy implementation plans must be applied at the water resource level and monitored to assess the effectiveness of policies for their effects on the status of water resources.
