ABSTRACT
Changing economic activity and
patterns of human habitation have long been a cause of concern for the
ecological health of the Hudson River and its
tributaries. Today, economic development
in the Hudson River Valley
is often characterized as a battle between proponents of economy-wide growth
and citizen groups concerned about the cumulative impact of incremental
development on the watershed. Current
development trends in the Hudson River
Valley are driving the conversion
of rural, agricultural and forestland to urban or industrial uses. This thesis is part of a larger study of the
economic changes that lead to land use and environmental changes. It focuses specifically on the economic
drivers of development in Dutchess
County, an area of the lower
watershed on the east bank of the Hudson,
midway between New York City and
the state capital of Albany. The objective was to engage the Dutchess County
planning community in developing a planning model, the economic portion of
which characterizes the economy with a Social Accounting Matrix (SAM)
referenced to a Geographical Information System (GIS). The model was used to assess economic impacts
of locally relevant development scenarios including a new IBM semiconductor
plant, agro-tourism, and commuting behavior.
These scenarios each discuss economic changes that have land use
consequences. For example, a new IBM
plant will likely instigate new residential development, agro-tourism offers a
way to keep land in agricultural use, and the study of commuting behavior leads
to insights on how residential growth may depend on commuting patterns, as well
as information on the effects of second home communities.
The final model will help
stakeholders to visualize not only how economic shocks will change their
communities, but also how these changes may lead to land use and cumulative
environmental impact. Stakeholders will
be able to visualize the trade-off between new economic growth and the possible
loss of environmental character in the county, and implement appropriate
policies to plan for a shared community vision of economic, social and
environmental goals.
