The abundant natural capital of the watershed of San Juan Bay Estuary is a critical part of the regional ecosystem and economy. The wetlands and mangroves of the coastline around the city of San Juan support rich biodiversity, erosion control, and moderate flood events. This first-ever Ecosystem Services Valuation of the watershed finds that its natural capital contributes $14 million to $61 million in ecosystem service benefits each year, around 33 percent of which are provided within San Juan’s municipal jurisdiction. Over a 100 year period at a three percent discount rate, this amounts to an annual asset value of between $447 million and $1.9 billion. With stewardship to maintain the health and function of that natural capital, this annual economic contribution can continue in perpetuity.
In collaboration with the USFS, Earth Economics presents a measurable framework for ecosystem goods and services, cultural services, and human well-being concepts. Cultural services often go unrecognized in land management and decision making for development plans, and thus risk degradation and loss. This report offers an approach to measure ecosystem services alongside cultural, social, and health benefits across the urban to rural gradient. The Green-Duwamish Watershed is highlighted to represent diverse land-use cases, from rural,indigenous groups to South Seattle's urban city dwellers.
This report evaluates the effect that calculating environmental benefits could have in two flood and stormwater mitigation case studies in Wisconsin: the first, a partially-funded property acquisition project in Jefferson County; the second, a stormwater mitigation project in the City of Portage. Integrating environmental benefits into hazard planning will enable local and state floodplain and emergency management professionals and stakeholder groups to use FEMA policy updates on benefit-cost analyses to fund innovative flood-risk reduction projects.
This report explores the importance of outdoor recreation in Whatcom County. The County's recreation-related businesses form an important hub of regional economic activity and contribute to the local tax base. This report includes an economic contribution analysis of outdoor recreation and further illustrates the value of Whatcom County's recreational lands through an ecosystem services valuation.
Pacific County’s nearshore ecosystems are valued at approximately $313 million to $3.1 billion dollars per year. This report offers recommendations for the preservation of ecosystems that contribute tangibly to the local economy. Furthermore, the report is aimed to support public and county decision-makers in understanding the economic context of project planning, policy choices, and other requirements particular to shoreline ecosystems and critical areas throughout the county.
This economic analysis estimates the value of the ecosystem services provided by natural assets in Pacific County’s nearshore environment. Pacific County’s nearshore ecosystems value at approximately $985 million to $4.4 billion dollars per year. Recommendations are offered for the preservation of ecosystems that contribute tangibly to the local economy. This report aims to support public and county decision-makers in understanding the economic context of project planning, policy choices and other requirements particular to shoreline ecosystems and critical areas throughout the county.
This report identifies several funding mechanisms that generate revenue of approximately $3 million. These resources are needed, in addition to existing sources of funding, to fully implement watershed maintenance and natural asset improvement projects to meet restoration goals of the Nisqually Watershed Recovery Program by 2055.
This report presents a technical valuation of the damages from dumping accumulated dam sediments in the Anchicaya River on Colombia's Pacific Coast. The unplanned discharge of more than 500,000 cubic meters of sludge in 2001 resulted in shocks to vulnerable ecosystems, severe damage to fish and shellfish, and harm to water supply, crops, and riverine and coastal mangroves. Earth Economics partnered with Fundacion Neotropica to conduct an economic valuation of the damages, emphasizing ecosystem connectivity and both market and non-market environmental impacts.
