Ecological infrastructure: landscape features that support ecosystem services. Their functions: Buffering the system against disturbances, e.g. riparian and wetland vegetation;
soils; floodplains; coastal dunes. Nature’s infrastructure has a positive impact on human resilience by :
Protecting human lives
Protecting engineered infrastructure
Enabling multiple land uses
When EI is degraded, land use options reduced, resulting lock-ins into single land use options
Navigating a new, sustainable future for the catchment
Developing a shared vision with stakeholders
Supported by good science
Developing and implementing a local management plan
Collaborative governance through a Catchment Forum
Adaptive co-management: learning, experimentation, reflection, adaptation
“Getting our act together for sustainable catchment management for resilient ecological infrastructure”
Christo Fabricius: Ecological Infrastructure and its implications for catchment management
1. Nature’s Infrastructure and its
implications for the management of
our Wilderness catchments

3. Nature’s Infrastructure
• The physical structures in the
landscape that support ecosystem
services:
– Riparian and wetland vegetation
– Soils
– Floodplains
• Functions:
– Buffering the system against
disturbances
– Regulating sediments and nutrients
4. People and Ecological Infrastructure
• Nature’s infrastructure has a positive impact
on human resilience by :
– Protecting human lives
– Protecting engineered infrastructure
– Enabling multiple land uses
• When EI is degraded, land use options
reduced, resulting lock-ins into single land use
options
12. Degradation of Ecological Infrastructure
• Development decisions use mostly social and
financial considerations
• Responses may result in short term
‘maladaptations’
• Unintended consequences
