What is Marxan with Zones?

Marxan with Zones is based on the same principles standard Marxan, but allows for multiple zones, zoning contributions, costs, and the spatial relationships between zones to all be considered in spatial optimization. This tool can be applied in various contexts to help identify configurations of sites (or ‘planning units’) that contribute to a wide range of ecological, social, cultural, and economic objectives. This makes Marxan with Zones well placed to support local and regional planning across marine, freshwater and terrestrial areas, where the goal is often to achieve a balance across a range of competing objectives.


WHAT IS THE DIFFERENCE BETWEEN MARXAN AND MARXAN WITH ZONES?  

Standard Marxan is essentially a one zone problem. It identifies priorities based on input data and parameters. Planning units are either selected or not selected. Marxan with zones solves the same problem as standard Marxan for each zone, as well as accounting for the relationships between different zones.
