The group around the South African Research Chair in Marine Ecology and Fisheries (SARCHI ME&F) is concerned with developing methodology for the implementation of an ecosystem approach to fisheries (EAF) in the Benguela large marine ecosystem, and more generally, methodology for a systems approach to managing human interactions with the ocean. This includes coping with, and adapting to, climate change in marine social-ecological systems.
The interdisciplinary team is led by Associate Professor Astrid Jarre and Dr Lynne Shannon.
We are affiliated with UCT’s Marine Research (MA-RE) Institute and UCT’s Centre for Statistics in Environment, Ecology and Conservation (SEEC). We are grateful for core funding by the DST/NRF South African Research Chair Initiative, and additional funding from the CEC, UCT, the NRF and UKRI/GCRF. Our professional network includes colleagues in South Africa, southern Africa and world-wide.
Assessing risks to marine ecosystems is critical due to their biological and economic importance, and because many have recently undergone regime shifts due to overfishing and environmental change. Yet defining
Ecological indicators used to monitor fishing effects in the context of climate change and variability need to be informative to enable effective ecosystem-based fisheries management. We evaluated the specificity of the response of ecosystem indicators to different fishing and environmental pressure levels using Ecosim and Atlantis ecosystem models for the southern Benguela ecosystem.
Ecological indicators are widely used to characterise ecosystem health. In the marine environment, indicators have been developed to assess the ecosystem effects of fishing to support an ecosystem approach to fisheries. However, very little work on the performance and robustness of ecological indicators has been carried out.
