What the study found
The review found that the ten catchment models commonly used in Aotearoa New Zealand could simulate one or more ecological criteria, but social-system coverage was much more limited.
Why the authors say this matters
The authors say these models are used for research and management of social–ecological systems, such as lakes and their catchments, and that advancing more holistic models could provide a basis for more integrated and effective management in the years to come.
What the researchers tested
The researchers conducted a literature review of ten catchment models commonly applied in Aotearoa New Zealand. They assessed the models against criteria for the ecological system (hydrology, sediment transport, contaminants) and the social system (economics, cultural values) in lake catchments.
What worked and what didn't
All of the reviewed models demonstrated capacity to simulate one or more ecological criteria. Only three of the models addressed the economics criteria within the social system, and the abstract does not report any models addressing cultural values.
What to keep in mind
The abstract does not describe detailed model-by-model results, and it does not provide specific limitations beyond noting trade-offs among models and the need for more holistic incorporation of the social system.
Key points
