Multispecies fisheries pose a considerable management difficulty with respect to quota allocation between species. Externalities of direct control over the harvest may include, among others, creation of unbalanced predator‐prey relationships in the environment. That, in turn, may affect the individual economic incentives of fishing vessels. Combining economic and ecological factors...
Maryland, Pennsylvania, Virginia, and West Virginia have all developed nutrient trading programs to defray the cost of achieving mandated nitrogen load reductions in Chesapeake Bay, and there is increasing interest in the role oysters can play in generating credits. A number of bioeconomic models highlight the impact these credits have...
The literature on ecosystem service valuation has grown considerably in the past decade as nations around the world have moved towards adopting more holistic, systems-level frameworks to managing both marine and terrestrial resources, ones recognizing and accounting for the interconnectedness of all parts of the ecosystem. In these frameworks, economic...
This fact sheet series highlights innovative ways that family forest and ranch owners are prospering from protecting and enhancing ecosystem services on their land. Ecosystem services are the benefits people receive from nature like water quality, wildlife habitat, and carbon sequestration.
Payments for ecosystem services (PES) are positive incentives offered to producers or resource owners in exchange for the provision of a given ecosystem service, such as biodiversity, water regulation, food, recreation and tourism. Interest in applying this economic instrument within the aquatic ecosystems has increased alongside a growing interest in...
We define the notion of sustainable yields for ecosystem, with particular
emphasis on long-run consistency between ecological and economic conflicting
objectives. We provide a way to compute sustainable yields by means of
a viability analysis of generic ecosystem models with harvesting. We apply
our approach to a Lotka–Volterra model of...
The project focuses on nonequilibrium ecosystem dynamics, a body of scientific research that characterizes and interprets ecosystem change. INR summarizes knowledge from this field, describes ways in which the current management framework may be inconsistent with scientific findings, and helps identify options for future management. This paper is designed to...
This literature review is the result of numerous searches via academic, and both governmental and non-governmental avenues including ISI Web of Science, the National Agricultural Library of the Agricultural Research Service (USDA), website of the Environmental Protection Agency, The U.S. Department of Energy, Agricola, J-stor, ArticleFirst, Academic Elite, National Academies...
By 1992, the Canadian cod populations collapsed and
a moratorium on fishing was declared, which
remains in place until today. Ecologists suspect that the marine ecosystem at the Canadian east coast
has
shifted towards a new regime, where cod stocks remain at a low level while other species biomass levels,...
Payments for Ecosystem Services (PES) is a relatively new tool for fisheries and aquaculture. Being part of the broader incentive- or market-based incentives, PES is a positive and voluntary incentive mechanism that compensates actors for increasing or maintaining the provision of ecosystem services. Our investigation considers potential and actual PES...
