Influence Of Psychological Factors On Climate Change Perceptions Held By Local Farmers In The Northeast Of Thailand, Suthirat Kittipongvises, Takashi Mino

Applied Environmental Research

Global climate change is considered one of the most critical socio-ecological challenges of the 21st century. In recent years extreme weather events have increased significantly in Thailand asin other parts of the world. In most cases, climatic variability has always been associated with its implications for agriculture. To date, however, there has been inconclusive understanding of farmers' capacity to detect climate change and its potential impact. This study therefore explores how Thai farmers perceive global climate change and, further, to examine the influence of psy-chological factors on these perceptions. The study used mixed research methods, with both quali-tative and quantitative …

The Human And Environmental Health Impacts Of Food Quality Among Emergency Food Providers, Alexina Cather

Master's Projects and Capstones

Abstract

Human health and environmental health are inextricably entwined, and the ways in which we grow, process, package, transport, market, and consume food are critical factors for both human and environmental health. The current industrial food system in the United States has numerous adverse effects on environmental and human health, which significantly impact the millions of food insecure Americans who receive their nutritional needs from emergency food providers (American Public Health Association, 2007). The widespread food insecurity in the United States and the increasing prevalence of obesity among adults and children have drawn attention to the role that emergency food …

Protecting Ecosystems, Culture, And Human Rights In Chile Through Indigenous And Community-Conserved Territories And Areas, William G. Crowley

Capstone Collection

In environmental conservation circles around the world, the contributions of indigenous peoples and local communities to the sustainable maintenance of ecosystems and natural resources are being given increased attention. Whether for cultural, spiritual, economic, or other purposes, the use of traditional and local knowledge of habitat and resource management is slowly making its way into the modern environmental movement, and is being incorporated into the dominant conservation paradigms. These managed areas, known as Indigenous and Community-Conserved Territories and Areas, or ICCAs, are defined by the International Union for Conservation of Nature as “natural and/or modified ecosystems containing significant biodiversity …

Simulating And Animating The Spatial Dynamics Of Interacting Species Living On A Torus, Boyan Kostadinov

Publications and Research

The goal of this talk is to present a student research project in computational population biology, which aims at creating a computer simulation and animation of the spatial dynamics of interactions between two kinds of species living on a torus-shaped universe. The habitat for spatial interactions is modeled by a 2D lattice with periodic boundary conditions, which wrap the rectangular grid into a torus. The spatial interactions between the species have two components: 1. Population dynamics modeled by the classical Nicholson-Bailey two-parameter family of models for coupled interactions between species, extended to incorporate space and 2. Two-parameter migration dynamics, modeled …

The Price Of Snow: Albedo Valuation And A Case Study For Forest Management, David A. Lutz, Richard B. Howarth

Dartmouth Scholarship

Several climate frameworks have included the role of carbon storage in natural landscapes as a potential mechanism for climate change mitigation. This has resulted in an incentive to grow and maintain intact long-lived forest ecosystems. However, recent research has suggested that the influence of albedo-related radiative forcing can impart equal and in some cases greater magnitudes of climate mitigation compared to carbon storage in forests where snowfall is common and biomass is slow-growing. While several methodologies exist for relating albedo-associated radiative forcing to carbon storage for the analysis of the tradeoffs of these ecosystem services, they are varied, and they …

Using An Obcd Approach And Landsat Tm Data To Detect Harvesting On Nonindustrial Private Property In Upper Michigan, Riccardo Tortini, Audrey L. Mayer, Pieralberto Maianti

College of Forest Resources and Environmental Science Publications

Forest dynamics influence climate, biodiversity, and livelihoods at multiple scales, yet current resource policy addressing these dynamics is ineffective without reliable land use land cover change data. The collective impact of harvest decisions by many small forest owners can be substantial at the landscape scale, yet monitoring harvests and regrowth in these forests is challenging. Remote sensing is an obvious route to detect and monitor small-scale land use dynamics over large areas. Using an annual series of Landsat-5 Thematic Mapper (TM) images and a GIS shapefile of property boundaries, we identified units where harvests occurred from 2005 to 2011 using …
