Tapping The Sweet Spot: Predicting The Suitability Of A Woodlot’S Potential To Transition Into A Productive Sugarbush In Maine, Deven M. Teisl May 2020

Tapping The Sweet Spot: Predicting The Suitability Of A Woodlot’S Potential To Transition Into A Productive Sugarbush In Maine, Deven M. Teisl

Non-Thesis Student Work

Through conversations with Dr. Sara Velardi, a postdoctoral research associate who has been doing research on maple producers’ scale management decisions in Maine, most current owners and operators in the maple syrup industry have the common interest of expanding their current operations, but they are unsure of how to approach that problem. Due to these current issues, my research focused on creating a sugarbush assessment tool. This assessment tool consists of a set of guidelines which can be utilized by current or future producers and can be used to easily assess woodlots without having to hire a consulting forester to …

Northern Conifer Forest Management: Silvicultural, Economic, And Ecological Outcomes From 65 Years Of Study, Maren Granstrom Dec 2019

Northern Conifer Forest Management: Silvicultural, Economic, And Ecological Outcomes From 65 Years Of Study, Maren Granstrom

Electronic Theses and Dissertations

While forest managers once sought primarily to produce sustainable revenue from harvests, there is now growing value placed on non-timber outcomes like wildlife habitat, climate adaptability, and carbon storage. When deciding how to manage land for the future, foresters and landowners must assess the many outcomes of forestry activities and be aware of the tradeoffs inherent to achieving different goals. Given the slow growth of trees relative to other commercial crops, it is rare to have the continuity of land ownership, researchers, and funding needed to follow a stand for a full rotation or to observe a tree from recruitment …


The Role Of Cooperation And Prosocial Behavior In Food Buying Clubs: An Exploratory Study, Afton Hupper May 2017

The Role Of Cooperation And Prosocial Behavior In Food Buying Clubs: An Exploratory Study, Afton Hupper

Honors College

Buying clubs arise when a group of individuals convenes to use their collective purchasing power to obtain bulk quantities of items, in this case food, at per-unit prices lower than offered by traditional grocers, or specialty items that are difficult to find. As cooperatively-structured groups, it is hypothesized that they function on the core principles of cooperation, reciprocity and other prosocial behaviors which support the benefit of the group rather than individual benefit. This research aims to test this by observing, identifying and analyzing behaviors which are instrumental in the success or failure of buying clubs, and by measuring cooperation …


Planning For Sustainability In Small Municipalities: The Influence Of Interest Groups, Growth Patterns, And Institutional Characteristics, Vanessa R. Levesque, Kathleen P. Bell, Aram J K Calhoun Jul 2016

Planning For Sustainability In Small Municipalities: The Influence Of Interest Groups, Growth Patterns, And Institutional Characteristics, Vanessa R. Levesque, Kathleen P. Bell, Aram J K Calhoun

Publications

How and why small municipalities promote sustainability through planning efforts is poorly understood. We analyzed ordinances in 451 Maine municipalities and tested theories of policy adoption using regression analysis.We found that smaller communities do adopt programs that contribute to sustainability relevant to their scale and context. In line with the political market theory, we found that municipalities with strong environmental interests, higher growth, and more formal governments were more likely to adopt these policies. Consideration of context and capacity in planning for sustainability will help planners better identify and benefit from collaboration, training, and outreach opportunities.

Sustainability's Inconvenient Discourse, Christine Gilbert May 2014

Sustainability's Inconvenient Discourse, Christine Gilbert

Honors College

“Sustainability” has been used to indicate certain values, market a way of life, and possesses a prominent role in a number of different disciplines, yet a commonly accepted definition doesn’t seem to exist. This thesis does not aim in any sense to define this elusive term, rather it examines the themes that inform discussions of sustainability. A number of particular thematic elements are used consistently across almost all of the discourses of sustainability: generational time frames, renewable resources, as well as the relationship between sustainability and economic development. Each unique discourse handles these themes in a specific way. What’s valuable …


Biodegradation And Feasibility Of Three Pleurotus Species On Cigarette Filters, Raymond Updyke Apr 2014

Biodegradation And Feasibility Of Three Pleurotus Species On Cigarette Filters, Raymond Updyke

Honors College

This study was designed to evaluate the biodegradation and feasibility of growing three oyster mushroom species - Pleurotus ostreatus, Pleurotus citrinopileatus, and Pleurotus djamor - on three different cigarette filter waste substrates: intact cigarette filters, blended cigarette filters, and smoked, intact cigarette filters. Cigarette filters are a common waste and are made primarily of cellulose acetate. Oyster mushrooms (Pleurotus spp.) have been shown to degrade synthetic polymers similar to cellulose acetate. In the experiment, the substrates were inoculated with mushroom spawn and placed in a growth chamber maintained at 24° C. After a six-week period, mycelium …


Wicked Tools: The Value Of Scientific Models For Solving Maine’S Wicked Problems, Tim Waring Jan 2012

Wicked Tools: The Value Of Scientific Models For Solving Maine’S Wicked Problems, Tim Waring

Maine Policy Review

“Wicked problems” are urgent, high-stake socioeconomic-environmental challenges that often involve ideological conflict and have no “best solutions.” Using examples from Maine’s Sustainability Solutions Initiative projects, Tim Waring describes how scientific models can be used to address these kinds of problems. When well-constructed and tested models are used to address policy-relevant issues, include input from stakeholders, and integrate social, economic and environmental dynamics, they can become “wicked tools” to address some of society’s biggest challenges.

Sustainability And Workforce Development In Maine, Catherine S. Renault, Linda Silka, James (Jake) S. Ward

Maine Policy Review

Maine is facing challenges in terms of its work­force: education levels lag behind those in the other New England states; population growth is slow; and the economy is undergoing a change that has shifted from manufacturing to more knowledge-based jobs. Catherine Renault, Linda Silka and Jake Ward discuss these challenges, looking at what employers want in their employees and at the kinds of jobs the state is likely to see in the future. They point out that the Sustainability Solutions Initiative, with its emphasis on a boundary-crossing approach to educa­tion, is an example of a way to train today’s students …


Economic Development And Maine’S Sustainability Solutions Initiative, Caroline L. Noblet, Kathleen P. Bell, Charles Colgan, Mario Teisl Jan 2012

Economic Development And Maine’S Sustainability Solutions Initiative, Caroline L. Noblet, Kathleen P. Bell, Charles Colgan, Mario Teisl

Maine Policy Review

The authors discuss how Maine’s Sustainability Solu­tions Initiative (SSI) can contribute to economic devel­opment in the state. SSI research is covering five of the seven targeted technology areas identified in recent reports as being important for economic development in the state (forestry and agriculture, environmental, information, composites, marine and aquaculture). The authors note how the broad scope of research carried out through SSI provides opportunities to catalyze new commercial opportunities. As important, SSI is providing many students with a unique learn­ing environment that will prepare them for the new knowledge-based economy.

Advancing Science And Improving Quality Of Place: Linking Knowledge With Action In Maine’S Sustainability Solutions Initiative, Damon Hall, Linda Silka, Laura Lindenfeld

Maine Policy Review

The authors give an overview of how research carried out through Maine’s Sustainabilty Solutions Initiative (SSI) improves traditional models of science by providing a fuller picture of the interaction between social and ecological systems. They provide examples of university-community research partnerships, where there is a continuous communication and feedback process that identifies problems and develops projects with a solutions-oriented focus. SSI projects, they argue, “focus on issues that may make lasting improvements to Maine’s quality of place.”

Sustainable Tourism Along Maine's Coast, Natalie Springuel Jan 2005

Sustainable Tourism Along Maine's Coast, Natalie Springuel

Maine Sea Grant Publications

Tourism is Maine's largest industry. In 2003, tourism generated $ 13.4 billion in sales of goods and services. In 2004, tourism provided for 176,633 jobs, generated $3.8 billion in wages, and $530 million in tax revenues. Governor John Baldacci formally recognized the economic and ecological importance of tourism by highlighting it as one of the five primary industries at the Governor's 2003 Conference on Natural Resource-based Industries. Access to the natural resource base, and the need to collaborate with other resource-dependent industries, were identified at the conference as cutting across multiple industries, including tourism. Since the Governor's Conference, several studies …


People In Nature: Environmental History Of The Kennebec River, Maine, Daniel J. Michor Jan 2003

People In Nature: Environmental History Of The Kennebec River, Maine, Daniel J. Michor

Electronic Theses and Dissertations

The quality of a river affects the tributaries, lakes, and estuary it feeds; it affects the wildlife and vegetation that depend on the river for energy, nutrients, and habitat, and also affects the human community in the form of use, access, pride, and sustainability. In an age of mass consumerism and materialism, dwindling natural resources and wild spaces, and advanced technology, the ability to make a living and at the same time enjoy the benefits of rural living is increasingly difficult. Using the entire Kennebec River watershed as the scale of investigation with particular focus on the river corridor itself, …
