To address these questions, we analyze the implementation of Massachusetts’
Wetlands Protection Act (MWPA), which has existed as a “natural
experiment” in community-based efforts to protect the environment for
over 20 years. We examine two
contrasting forms of community-based environmental protection (CBEP): (non-bylaw)
communities versus (bylaw) communities.
The non-bylaw approach is a “weak” form of CBEP in which town
(volunteer) conservation commissions act as an implementing agents for the
state Department of Environmental Protection, where state regulations and
oversight strongly proscribe local environmental decision-making (189
towns) in protecting wetlands. In
contrast the bylaw approach is a “strong” form of CBEP where town
(volunteer) conservation commissions act to protect wetlands under their
own locally-produced bylaws and rules, independent of state regulations
and oversight (161 towns).
It is the comparison of these two forms that interests us. In a
broad-based statistical analysis we are examining the record of wetlands
protection across all 351 Massachusetts
towns. Combining graphic
information system (GIS) data, site-specific wetlands permitting data, and
community socio-economic data we address the questions posed above in the
specific context of wetlands protection.
Our analytic approach involves four innovations over existing
studies. First and foremost we
devise a set of consistent, reliable, and substantively meaningful
measures of environmental performance across communities. Second, we set
up a design that controls for the many confounding influences and
characteristics that have plagued the analytic utility of prior
scholarship on CBEP. Third,
and derived from the above, we devise consistent and rigorous measures for
categorizing communities most directly relevant to evaluating
environmental decision-making. Fourth
we study a single environmental domain – wetlands – that is broadly
salient to community development policy and politics.
