From: Scenario planning from the bottom up: supporting inclusive and ecosystem-based approaches to marine spatial planning

Fig. 3

Aggregation index (ranging from 0–100, disaggregated to aggregated, respectively) and total cost of zoning PUs to a zone for each zone for four zoning scenarios with (a, b) and without (c, d) mandatory allocation of PUs to a zone, respectively. Cost is explained in the ‘Methods’ section: development of scenarios and Cost layer, and refers to the user-defined cost of assigning each planning unit to a zone.
