The Western Cape of South Africa is experiencing severe threats from increasing flooding. In the Drakenstein municipality, flooding from the Berg River and its tributaries has caused severe damage to housing, transportation, and health infrastructure. Resulting from a combination of climate-related extreme rainfall, human encroachment on floodplains, and degraded river and wetland systems, severe flooding is threatening the health and safety of communities, the local economy and biodiversity.
River restoration has the potential to absorb some of these impacts. Just 10% of rivers in the Western Cape are considered ecologically healthy, with the remainder classified as degraded. Well-functioning rivers provide essential ecosystem services such as flood protection, water supply for agriculture, domestic use, recreation, and industry, while also functioning as valuable assets for tourism and culture.
To address the climate risks and improve water management, Drakenstein is exploring the use of Nature Based Infrastructure (NBI). As part of the project “Transformative Adaptation in the Berg River Catchment through Nature-Based Solutions” it aims to strengthen existing riverine management initiatives and identify pilot NBI projects measures based on climate change vulnerability analysis. The goal is to increase flood resilience and water retention by rehabilitating riverbanks, riparian areas, and floodplains.
The Sustainable Asset Valuation (SAVI) report will explore the outcomes of investing in NBI in river sub-catchments between the cities of Paarl and Wellington. We will assess two scenarios:
The NBI Global Resource Centre aims to bring together key partners to establish a business case for Nature-Based Infrastructure (NBI).
