This dissertation consists of three essays that collectively address the importance of accounting for spatial heterogeneity and spatial dependence of environmental assets and natural resources in policy making. The first essay examines the value of different wetland ecosystem services using an expanded meta-dataset of valuation studies in North America. The...
We present the outlines of an integrated economic-ecological framework
designed to help assess the implementation of the ecosystem-based
management (EBM) of fisheries in New England. We develop the
framework by linking a computable general equilibrium (CGE) model of a
coastal economy to a bottom-up model of a marine food web...
Grazing of riparian forage by livestock may alter stream channel morphology in ways that impact nearby aquatic habitat, bank stability, vegetative cover and water quality. A number of grazing management practices have been proposed as a means to reduce the amount of time cattle spend in the riparian zone. The...
Wildlife managers are on the front lines of the effort to conserve wildlife and
are required to do so cost-effectively. This dissertation consists of three manuscripts
that integrate economics and ecology to inform cost-effective wildlife management.
The first and second manuscripts focus on identifying cost-effective wildlife
management plans. The third...
With growing concerns on environment impact of industrial product development, the product developers are seeking better solutions to achieve desired environmental benign requirements by the regulators and customers besides economic growth. During the last decade, some of the most successful product development companies (such as HP) have established their own...
This investigation was undertaken to characterize and evaluate
the forage production and utilization of the successional vegetation
of the mixed conifer forest.
Field studies were carried out during the summers of 1962
through 1964 at the Eastern Oregon Experiment Station Hall Ranch
which is located 12 miles southeast of Union,...
The last five decades of research in arid land ecology cites Invasive species as a source of imbalances in biodiversity through habitat destruction and reductions of native species through ecosystem alterations in favor of non-native species. Invasive species are known to damage not only the surrounding ecosystem but also cause...
This dissertation investigates livelihood and land use change dynamics in a community at the farm-forest periphery in highland Ethiopia. I use interviews and livelihood assessment data to compare the strategies used by members of different wealth groups to negotiate and maintain access to forest resources, and integrate socioeconomic, bio-physical and...
