Assignment 1: Project Topic Interests and Spatial Questions
Topic 1: Assessing a community’s vulnerability to climate change as seen in rising sea
levels and increased severity and frequency of natural disasters
Summary: In light of Hurricane Irene’s impact on the East Coast, I’d like to assess the
vulnerability of different communities in their capacity to mitigate any damage from
issues associated with climate change, including greater frequency and severity of natural
disasters and rising sea levels. Most likely, I’ll focus on a coastal community that is
facing rising sea levels and associated problems such as erosion. Socio-economic and
physical variations among coastal communities may have two important effects on their
capacity to deal with climate change. Greater development may increase the monetary
damage from rising sea levels while also increasing a community’s financial capacity
(and motivation) to deal with and perhaps prevent coastal damage from climate change.
Thus, this issue represents an important facet of climate and environmental justice, two
movements that seek equity in terms of environmental “goods” and “bads”.
Questions
- What are the variables that make a community more or less vulnerable to major damage
from rising sea levels and other climate change-related problems?
- Variables to measure could include income, occupation (dependency on coastal
location or access to water), population demographics (elderly? educated?
temporary vs. permanent residents?), type and amount of shore development,
weather patterns, and access to social services, land cover
- What is the relationship between recent trends in these variables (increased or decreased
development, for example) and the growing threat of sea-level rise? Furthermore is there
a relationship between certain types of development and the impact of economic growth
on a community’s ability to adapt to climate change (which may counteract the negative
impacts of shore development)?
This assessment could provide useful information on how best to locate and plan future
coastal communities to prevent or limit damage from rising sea levels.

it relates to dealing with storm surges from major weather events. It could be helpful in
connecting my research on the vulnerability of East Coast communities to storms like
Hurricane Irene.

Topic 2: Childhood obesity and access to athletic organizations, clubs, and classes
Summary: According to the CDC, no state had a prevalence of obesity less than 20% in
2010 and many states had rates of 30% or higher. Childhood obesity has become an
alarming trend in the United States with over 15% of all children and adolescents
affected, a threefold increase from twenty years ago. I’m interested in looking at the
prevalence of childhood obesity in the Boston area and determining if a relationship
exists between access to athletic activity (physical education classes, after-school sports,
gyms and public courts/field) and obesity rates. This is especially crucial given the major
cuts seen in funding for public community-based recreational opportunities for children
such as sports leagues and open-access parks and fields.
Questions
- What is the relationship between access to athletic activity opportunities
(measured in terms of proximity to parks, support of physical education and after
school sports programs) and childhood obesity? How does access incentivize
activity in children and adolescents?
- Are children of certain socio-economic levels more vulnerable (do they already
exhibit less healthy eating habits and greater exposure to other health-impairing
-
toxins) to cuts in physical education programs that could undermine their overall
health and well-being?
How effective have community-based campaigns been in promoting a more active
lifestyle and reducing childhood obesity?
These questions (and their answers) could support reinstating or increasing
funding for physical education and after school sports programs and could help
identify the most effective ways to increase physical activity in children and
adolescents and combat childhood obesity.

This analysis reveals many of the challenges of using GIS to study access to
parks, such as the pitfalls of the “container” approach, but also provides good
background information on layering parks data with demographic data and analyzing for
significant relationships.

This project (and the associated website) provides a lot of useful information on
the relationships between city planning and public health, especially as it relates to
eating habits and physical activity. The project also references studies that focus on the
relationship between one’s environment (access to athletics facilities, safety of
community, transportation use, food choices) and one’s level of physical activity.

This paper focuses on the different methods for determining access to parks which
can better demonstrate “true” levels of access. Using the street network buffer method
will be important as I analyze the relationship between accessibility and childhood
obesity.
