The New England Sustainability Consortium
The New England SusTainability Consortium (NEST) is a regional research partnership focused on strengthening the scientific basis for decision-making for sustainability challenges where economic and community development goals need to be balanced with environmental protection.
NEST researchers from Maine, New Hampshire, and Rhode Island come together to use sustainability science that focuses on producing knowledge and linking it to actions that improve human well-being and preserve our planet’s life-support systems.
The Future of Dams Project
There are more than 14,000 dams on New England’s rivers, and many are small, aging, or derelict. The number of potential options for aging dams make decisions about their future complex, and the important human and ecological dimensions of dams bring a wide range of stakeholders to the table when considering their fate. The Future of Dams project aims to empower stakeholders with scientific knowledge to make difficult decisions about aging or failing dams.
NH Residents Surveyed on Options for Aging Mill Dams
Old dams present a policy dilemma. If nothing is done, they will continue to deteriorate, potentially with bad results. Yet maintenance and upgrades are expensive. A new study by Future of Dams researchers and the Carsey School of Public Policy sheds light on NH residents' preferences about these dams.
NH Public Radio: UNH Survey: Most N.H. Residents Prefer Dam Removal
Dam decision makers try to balance competing uses and management objectives when making decisions about the future of a dam. MCDA is a structured decision making framework, useful for addressing such complexity.
We monitored fish passage on the Pawcatuck River in Rhode Island after a series of dam removals and construction of technical fishways and nature-like fishways, documenting the extent of diadromous fish migration up the river.
Small unmanned aerial systems (sUAS, a.k.a. “drones”) may provide new effective ways of studying river systems and how they physically change with restoration efforts.
Using Remote Sensing to Estimate Impounded Sediment Volume and Dominant Grain Size at Dams in New England
A comparison between surveyed New England dams to examine how the volume and grain size of impounded sediment is related to sediment supply, sediment transport in streams and rivers, and dam trap efficiency.
Geospatial data is an essential tool in determining the fate of dams in New England and beyond. Having these resources available in one place can be helpful to land managers, stakeholders, and researchers.
Understanding the consequences of dam passage on migrating eels is critical for managing populations and informing decision making for current and future hydroelectric operations.
MDA is a useful tool in understanding how news media characterize dam decisions, which is important because the public record can inform the meanings that can be made about dams and rivers.
Because dams often create reservoirs that may retain nitrogen, we explored the implications of dam removals on nitrogen flux from New England watersheds.
Using citation analysis methods and a structured survey of federal and state resource agency stakeholders to investigate the use of best available science in relicensing decisions.
This study aims to give a detailed analysis of a dam removal’s impact on housing prices to give policy makers and homeowners more information when faced with dam removal decisions.
Public Preferences for Ecosystem Services from Dam Removals: A Nonmarket Valuation Approach to Improve Decision-Making
Lacking reliable price information, values of ecosystem services are omitted from cost-benefit analyses, but nonmarket valuation allows us to uncover those prices so that decisions about dams can more easily incorporate a wider range of impacts.
