South Platte Watershed Natural Capital Resource Assessment

South Platte Watershed Natural Capital Resource Assessment

The South Platte Natural Capital Assessment is a collaborative natural capital assessment involving over 50 public and private stakeholders. The goal of the partnership is to engage stakeholders in protecting and restoring the watershed's lands and waters. For this report the team catalogued existing data sources, identified the most important natural assets, mapped natural capital, and valued the ecosystem services produced throughout the watershed. A decision-support tool was produced to assist stakeholders with prioritizing future investments, whether for preservation or conservation.

This report suggests that the Watershed provides extensive value, approximately $7.4 billion per year in ecosystem services, to the economy and residents.

Flood Damage in the Skykomish Watershed

Flood Damage in the Skykomish Watershed

Benefit-cost analysis can be used to tie together various stakeholder interests and perspectives in a single comprehensive analysis. Snohomish County and the Sustainable Lands Strategy stakeholders are currently considering several courses of action that address floodplain management in the Lower Skykomish reach. Earth Economics has been asked to provide a holistic benefit-cost analysis framework that incorporates benefits and costs associated with economic, environmental, and social impacts to be used as a decision support tool. A holistic benefit-cost analysis is key to advancing the SLS goals of safeguarding the agricultural sector, restoring and protecting salmon habitat, and reducing flood damage.

Nature's Value in the Skykomish Watershed

Nature's Value in the Skykomish Watershed

This report values some of the ecosystem goods and services provided by the Lower Skykomish Reach and the Braided Reach, including their associated sub-basins, in the Snohomish Watershed in Western Washington State. Our analysis reveals that the combined ecosystems of the Lower Skykomish and Braided Reach provide between $888 million and $1.6 billion in economic value every year.  In present terms, the Lower Skykomish Reach and the Braided Reach are valued between $89 billion and $166 billion when considering a 100-year timeframe.   

The Value of Natural Capital in the Columbia River Basin: A Comprehensive Analysis

The Value of Natural Capital in the Columbia River Basin: A Comprehensive Analysis

The Columbia River Basin is an abundant watershed, supporting immense forests, the largest salmon runs in the world, and diverse and abundant wildlife. These natural resources benefit our region with sustainable food, jobs, recreation, clean water, and a healthier environment, among many others. Yet, these natural resources have been seriously degraded by dams and other developments in the basin. When assets, whether built or natural, are not managed sustainably, economic loss occurs.

The Value of Natural Capital in the Columbia River Basin report shows the immense economic value of the Columbia River Basin’s natural assets and provides clear evidence of the increased value that can be gained by addressing ecosystem-based function in the Columbia River Basin river management.

 

The Economic Impact of the 2016 Loma Fire

The Economic Impact of the 2016 Loma Fire

The Santa Clara Valley Open Space Authority (OSA) requested this comprehensive cost analysis of the September 2016 Loma Fire in Santa Clara County to better understand the challenge and to begin a discussion about changes in policy and stewardship that would reduce the scale and cost of future wildfire events.

Natural Capital Benefits of the San Juan Bay Estuary Watershed

Natural Capital Benefits of the San Juan Bay Estuary Watershed

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. 

Natural Resources Accounting: A Path Forward for the Governmental Accounting Standards Board

Natural Resources Accounting: A Path Forward for the Governmental Accounting Standards Board

Accurate accounting is essential for sound decision-making by the public, policymakers, and investors. High-quality accounting standards are also essential to the efficient functioning of our capital markets. Currently, accounting standards do not address natural assets such as watersheds, aquifers, or other green infrastructure, even though these can often be among an agency’s most important assets. Earth Economics prepared this report for the Governmental Accounting Standards Board (GASB) and their Advisory Council (GASAC), proposing a sequence of steps the GASB can take to address natural resources in accounting, ranging from clarifying existing accounting rules to developing new accounting rules.

Why We Continue to Develop Floodplains: Examining the Disincentives for Conservation in Federal Policy

Why We Continue to Develop Floodplains: Examining the Disincentives for Conservation in Federal Policy

This report explores the value of floodplains and attempts to explain how the nation's rivers and floodplains have become physically disconnected, leading to loss of floodplain functions. With federal agencies now incorporating the value of natural infrastructure into federal planning and decision-making, there are opportunities as never before to examine and change the disincentives for floodplain conservation.
