Over the past five years, the project has explored the conceptual and philosophical basis for investing in Ecological Infrastructure (EI) and through this report, demonstrates how EI can be utilised to secure water for the benefit of society through research focused on selected case studies in the uMngeni Catchment.
There is an interdependent and co-constitutive relationship between EI, society and water security. Through the study, we identify approaches in the uMngeni Catchment where investment into the maintenance and/or rehabilitation of EI can produce long-term and sustainable returns for the delivery of water-related ecosystem services. The study inherently addresses aspects of water quantity and quality, economics, societal interactions, environmental systems and the governance of natural resources. It highlights that ensuring availability and sustainable management of water resources requires both transdisciplinary and detailed biophysical, economic, social and development studies of both formal and informal socio-ecological systems. It also argues that the human resources capacity to support these studies is critical to sustainable and transformative outcomes.
