From Fail-Safe To Safe-To-Fail: Sustainability And Resilience In The New Urban World, Jack F. Ahern Apr 2011

From Fail-Safe To Safe-To-Fail: Sustainability And Resilience In The New Urban World, Jack F. Ahern

Landscape Architecture & Regional Planning Studio and Student Research and Creative Activity

Abstract: The extent to which the 21st Century world will be "sustainable" depends in large part on the sustainability of cities. Early ideas on implementing sustainability focused on concepts of achieving stability, practicing effective management and the control of change and growth-- a "fail-safe" mentality. More recent thinking about change, disturbance, uncertainty, and adaptability is fundamental to the emerging science of resilience, the capacity of systems to reorganize and recover from change and disturbance without changing to other states-- in other words, systems that are "safe to fail." While the concept of resilience is intellectually intriguing, it remains largely unpracticed …


Bioretention: Evaluating Their Effectiveness For Improving Water Quality In New England Urban Environments, Mary Dehais Jan 2011

Bioretention: Evaluating Their Effectiveness For Improving Water Quality In New England Urban Environments, Mary Dehais

Masters Theses 1911 - February 2014

Nonpoint source (NPS) pollution is one of the leading causes of water quality problems in the United States. Bioretention has become one of the more frequently used stormwater management practices for addressing NPS pollution in urbanized watersheds in New England. Yet despite increased acceptance, bioretention is not widely practiced. This study explores and evaluates the efficacy of bioretention for protecting urban water quality.

This research found that numerous monitoring methods are used by researchers and industry experts to assess the effectiveness of stormwater best management practices (BMPs) and low impact development (LID) practices that include bioretention. The two most common …


An Ecosystem Approach To The Sustainability Of Urbanizing Watersheds, Sarah L. Raposa Jan 2011

An Ecosystem Approach To The Sustainability Of Urbanizing Watersheds, Sarah L. Raposa

Masters Theses 1911 - February 2014

Political boundaries make watershed planning difficult despite the influence of many state and federal programs. Broad, top-down, watershed initiatives fail to reach many municipalities due to human resources, time and legalities. Thus, a watershed ecosystem based approach to city planning should be utilized in order to integrate a holistic and scientific foundation for land use decisions. However, there is a need for research for developing and applying a watershed approach to urbanizing watersheds.

The goal of this study is to provide a series of science based transferable recommendations upon which municipalities can make land use planning decisions. These recommendations are …


Building Integrated Aquaculture, Erik A. Woodin Jan 2011

Building Integrated Aquaculture, Erik A. Woodin

Masters Theses 1911 - February 2014

Exploratory research into a fresh concept, building integrated aquaculture, has found new information on the topic. Motives indicating building integrated aquaculture is important for sustainable development were identified. A review of the literature found relatively little in the way of experiments, aquaculture operations, and case studies which documented or demonstrated a deep understanding of the interactions between building and aquaculture systems. A simple experiment was conducted observing thermal energy and moisture interactions in simulated aquaculture facilities, some with tank covers and insulation. Two different retrofit programs were developed in a case study of building integrated aquaculture for an existing structure …

If landscape architecture can intertwine with the practice of social justice, how should academic training provide an atmosphere where this correlation is developed? In a professional degree program, such as landscape architecture, there are a plethora of skills among students that can be utilized no only in their future careers, but during their academic experience. By learning the tools while implementing them, there is a profound educational …
