This Massachusetts Division of Ecological Restoration (DER) study evaluates the effectiveness of dam removal along waterways. Findings show that dam removal is less expensive than repairing and maintaining dams, reduces flood risk to surrounding properties, and creates better stream habitat.
This resource offers an extensive list of studies, papers, and articles on the economic benefits of river conservation, with summaries of their content.
Wetlands filter and clean water, which decreases the costs of drinking water treatment, and they reduce the frequency and intensity of floods. They support the life cycle of 75% of the fish and shellfish commercially harvested in the U.S., and up to 90% of the recreational fish catch. For example, in South Carolina it would require a $5 million treatment plant to remove the pollutants filtered by the Congaree Bottomland Hardwood Swamp.
Study shows that annual sport fishing activity in this Alaska municipality generates more than $63 million in spending on goods and services, accounting for over 900 jobs. Fishing also produces over $6 million in state and local taxes.
The destruction of mangroves has a strong economic impact on local fishing communities and on food production in the region. Mangrove-related fish and crab species account for 32% of the small-scale fisheries landings in the region. The annual economic median value of these fisheries is $37,500 per hectare of mangrove fringe, falling within the higher end of values previously calculated worldwide for all mangrove services together.
A first-ever analysis released by the Chesapeake Bay Foundation finds that the economic benefits provided by nature in the Chesapeake Bay watershed will total $130 billion annually when the Chesapeake Clean Water Blueprint, the regional plan to restore the Bay, is fully implemented. The Economic Benefits of Cleaning up the Chesapeake also reveals that in Pennsylvania, those annual benefits will approach $40 billion.
This report provides an in-depth look at the declining environmental health of the Jersey shore and an examination of the impact this has on New Jersey’s economy. New Jersey’s tourism, municipal water supplies and coastal fisheries depend on the health of the Jersey Shore. The declining health has caused a 20% decrease in total commercial fishery revenues and the need to install a $5 million desalination plant in Cape May.
Study shows that coastal wetlands reduce the damaging effects of hurricanes on coastal communities, saving lives and minimizing property damage.
