Data-Driven Agriculture For Rural Smallholdings, Kerry Taylor, Martin Amidy Jul 2021

Data-Driven Agriculture For Rural Smallholdings, Kerry Taylor, Martin Amidy

Journal of Spatial Information Science

Spatial information science has a critical role to play in meeting the major challenges facing society in the coming decades, including feeding a population of 10 billion by 2050, addressing environmental degradation, and acting on climate change. Agriculture and agri-food value-chains, dependent on spatial information, are also central. Due to agriculture's dual role as not only a producer of food, fibre and fuel, but also as a major land, water and energy consumer, agriculture is at the centre of both the food-water-energy-environment nexus and resource security debates. The recent confluence of a number of advances in data analytics, cloud computing, …


A Climate Chronology, Sharon S. Tisher Mar 2021

A Climate Chronology, Sharon S. Tisher

School of Economics Faculty Scholarship

The most challenging of all endeavors in human history will likely be that of understanding the impact of our industrial and technological enterprises on the planet’s climate and ecosystems, and responding effectively to the threats posed by that impact. I began writing this chronology while developing a climate policy course at the University of Maine. It has grown substantially during the ensuing nine years, and continues to grow.

By juxtaposing developments in climate science, U.S. policy, and international policy over the previous two centuries, I hope to give the reader new insights into where we have been, where we are …


Ecological And Economic Implications Of Increased Storm Frequency And Severity For Boreal Lakes, Kathryn Warner May 2019

Ecological And Economic Implications Of Increased Storm Frequency And Severity For Boreal Lakes, Kathryn Warner

Electronic Theses and Dissertations

In boreal regions, increased precipitation events have been linked to increased concentrations of dissolved organic carbon (DOC), however less is known about the extent and implications of these events on lakes. We assessed the effects of precipitation events on six drinking water lakes in Maine, USA to better understand how DOC concentration and quality change in response to precipitation events. Our results revealed three types of responses: (1) an initial spike in DOC concentrations and quality metrics; (2) a sustained increase in DOC concentrations and quality metrics and; (3) no change during all sampling periods. Lake residence time was a …


Forecasting Labor Force Participation At The Regional Level In The United States: The Case Of Maine, Maryam Kashkooli May 2018

Forecasting Labor Force Participation At The Regional Level In The United States: The Case Of Maine, Maryam Kashkooli

Honors College

This project attempts to investigate the future of labor force participation in Maine using an econometric forecasting approach. Forecasting has become an increasingly popular form of statistical analysis which uses historical distributions to help estimate future distributions of econometric models. There exists extensive literature on forecasting employment, however the literature on forecasting labor force participation is relatively small. I adapt existing econometric models and make use of time series information on sociodemographic factors such as age and net migration in order to determine how Maine’s changing demographic structure is affecting its labor force and how these effects will carry on …


Sustainability Science: A Call To Collaborative Action, David D. Hart, Kathleen P. Bell Apr 2013

Sustainability Science: A Call To Collaborative Action, David D. Hart, Kathleen P. Bell

Publications

Sustainability science is an emerging field directed at advancing sustainable development. Informed by recent scholarship and institutional experiments, we identify key roles for economists and encourage their greater participation in this research. Our call to collaborative action comes from positive experiences with the Sustainability Solutions Initiative based at the University of Maine, where economists collaborate with other experts and diverse stakeholders on real-world problems involving interactions between natural and human systems. We articulate a mutually beneficial setting where economists’ methods, skills, and norms add value to the problem-focused, interdisciplinary research of sustainability science and where resources, opportunities, and challenges from …


Saltwater Fishing In Cobscook Bay: Angler Profile And Economic Impact, Christopher Bartlett, Kevin Athearn Ph.D Nov 2008

Saltwater Fishing In Cobscook Bay: Angler Profile And Economic Impact, Christopher Bartlett, Kevin Athearn Ph.D

Maine Sea Grant Publications

This Research in Focus fact sheet profiles the economic impact of recreational fishing in Downeast Maine. Extension associate Chris Bartlett worked with University of Maine-Machias researcher Kevin Athearn to survey recreational fishers in the Cobscook Bay region. This research is informing sustainable development initiatives in Washington County.


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 …
