Relative values for open space proximity source, use, and flows source, under alternative urban growth scenarios Green-Duwamish watershed, WA, USA.

<p>Relative values for open space proximity source, use, and flows source, under alternative urban growth scenarios Green-Duwamish watershed, WA, USA.</p

Open space proximity flows in the Green-Duwamish watershed under baseline conditions and constrained and open urban-growth scenarios.

<p>Theoretical values are in relative rankings, ranging from 0 to 100 for each cell. When multiple users have access to one source of proximity value, the value for this non-rival service is multiplied by the number of users, so total flow values can exceed 100.</p

A simplified image of a small part of the ARIES knowledge base.

<p>The MEA ES categories on the left are broken down into the benefits in the middle, only some of which (in blue) are directly connected to beneficiaries. Dashed lines exemplify indirect relationships that, when taken as the description of legitimate ecosystem services, have the potential of causing “double counting” by identifying benefits that are “intermediate” and not “final”, i.e., not directly linked to beneficiaries. Beneficiaries are depicted on the right, with non-rival benefits in green and rival benefits in orange.</p

Water supply and quality in the CAZ area of Madagascar.

<p>From the left: total water demand across sectors, surface-water flow that is used by beneficiaries, and amount of sediment that is transported by hydrologic flows. Regions 1 and 2 (outlined in red) show the areas selected for comparison; the CAZ boundary is shown in black.</p
