For example, it is easier to measure the quantity of sediment in a stream near the intake for a water treatment • Non-market valuation estimates value in cases where plant than to observe the interaction between the sediment in an ecosystem service has no market price or satisfactory the water and the plant’s equipment, particularly as it is difficult market proxy. [...] Economic activity: The ecological value of a hectare of land depends on its • The more economic activity nearby, the higher the value of surroundings ecosystem services.38 Many studies give a single estimate of the ecosystem services • Studies often use “gross cell product,” a spatially provided by one hectare of a healthy ecosystem. [...] In this equation, L is the have diminishing returns to scale in providing ecosystem pollutant load remaining after the water has gone through the services, ecosystem services have diminishing returns to scale in buffer; W is the width of the buffer; and ●w is the fraction of the generating economic value. [...] The former is better for demonstrating the magnitude of impacts, while the latter is better for demonstrating the potential • Be aware of the study’s approach and data sources. [...] rate of 3%, in line with average values for the region’s capital projects, the project would have the following annualized cost: For conservation and restoration projects where economic values are not available for the area conserved or restored, some ecological data is needed to establish how valuable the project site is as a fishing spot compared to the site at which the economic values were cal.
