Resource trade-off models

Resource trade-off models are spatial models that use biological, environmental and socio-economic data to optimise management (protected area designation) across potentially conflicting uses, or across different ecosystem services.

Software used includes Zonation (Moilanen et al. 2009) and Marxan (Ball et al. 2009).

Model summary

Recent applications of the resource trade-off model include Chatham Rock Phosphate Environment Protection Authority application; the Ross Sea, Antarctica MPA application; South Pacific Regional Fisheries Management Organization Vulnerable Marine Ecosystem taxa analysis.
