Valerie Esposito , University of Vermont. The importance and contribution of healthy ecosystems to human well-being and poverty reduction have gained increasing awareness and attention in recent years. Despite this wide-scale acknowledgement, the majority of the benefits yielded by ecosystem services are currently exogenous to the economic system, so their value is not equally weighted in decisions that directly impact their functioning and welfare. Public understanding of the importance of these contributions and the necessity of healthy ecosystems and sound management is vital for their conservation.

Mahir Demir , University of Tennessee Follow. This dissertation considers the use of food chain models coupled with optimal control theory as a new approach for the problem of implementing ecosystem-based fishery management EBFM strategies. Because of the availability of temporal data, we build our first food chain model using ordinary differential equations to describe the anchovy dynamics, and then build our second food chain model using partial differential equations to include spatial features of the anchovy dynamics. In the study, we use the harvest rate of the anchovy fishery as our control that corresponds to number of fishing fleets. In the first model, the Black Sea anchovy stock was coupled with a prey and a predator species, using a system of nonlinear differential equations. The objective for the problem is to find the ecosystem-based optimal harvesting strategy that maximizes the discounted net value of the anchovy population with seasonal harvesting. In our numerical simulations, we obtained more profitable harvesting strategies for the southern part of the Black Sea, and also obtained much better structure for the related food web in terms of population biomasses via the optimal control strategy.
The Ecosystem Management Decision Support EMDS system is an application framework for knowledge-based decision support of ecological analysis and planning at any geographic scale. EMDS integrates state-of-the-art geographic information system GIS as well as logic programming and decision modeling technologies on multiple platforms Windows, Linux, Mac OS X to provide decision support for a substantial portion of the adaptive management process of ecosystem management. The NetWeaver component performs logic-based evaluation of environmental data, and logically synthesizes evaluations to infer the state of landscape features such as watersheds e.
Evaluate the importance of ecosystem management and protection Every living thing on Earth belongs to an ecosystem. An ecosystem can be as small as a puddle or as large as an ocean. No matter its size, every ecosystem is vital to life on Earth, and requires human respect, support, management and protection.
