Strong feedback between global biodiversity loss and persistent, extreme rural poverty are major challenges in the face of concurrent food, energy, and environmental crises. This paper examines the role of industrial agricultural intensification and market integration as exogenous socio-ecological drivers of biodiversity loss and poverty traps in Latin America. We then analyze the potential of a food sovereignty framework, based on protecting the viability of a diverse agroecological matrix while supporting rural livelihoods and global food production. We review several successful examples of this approach, including ecological land reform in Brazil, agroforestry, milpa, and the uses of wild varieties in …

Confronting Uncertainty In Wildlife Management: Performance Of Grizzly Bear Management, Kyle A. Artelle, Sean C. Anderson, Andrew B. Cooper, Paul C. Paquet, John D. Reynolds, Chris T. Darimont

Wildlife Population Management Collection

Scientific management of wildlife requires confronting the complexities of natural and social systems. Uncertainty poses a central problem. Whereas the importance of considering uncertainty has been widely discussed, studies of the effects of unaddressed uncertainty on real management systems have been rare. We examined the effects of outcome uncertainty and components of biological uncertainty on hunt management performance, illustrated with grizzly bears (Ursus arctos horribilis) in British Columbia, Canada. We found that both forms of uncertainty can have serious impacts on management performance. Outcome uncertainty alone – discrepancy between expected and realized mortality levels – led to excess mortality in …

Coupling Self-Organizing Maps With A Naïve Bayesian Classifier: Stream Classification Studies Using Multiple Assessment Data, Nikolaos Fytilis, Donna M. Rizzo

College of Engineering and Mathematical Sciences Faculty Publications

Organizing or clustering data into natural groups is one of the most fundamental aspects of understanding and mining information. The recent explosion in sensor networks and data storage associated with hydrological monitoring has created a huge potential for automating data analysis and classification of large, high-dimensional data sets. In this work, we develop a new classification tool that couples a Naïve Bayesian classifier with a neural network clustering algorithm (i.e., Kohonen Self-Organizing Map (SOM)). The combined Bayesian-SOM algorithm reduces classification error by leveraging the Bayesian's ability to accommodate parameter uncertainty with the SOM's ability to reduce high-dimensional data to lower …

Estimations Of Flood Waste From Rural Dumpsites Located On Floodplains From Neamţ, County, Romania, Florin C. Mihai

Florin C MIHAI

Waste dumping is a serious environmental threat to major rivers from extra- Carpathian Region of Neamţ county in the proximity of villages because the lack of waste collection services. In this context, floodplains are frequently susceptible to such bad practices, these areas being also exposed to stronger floods. The paper aims to calculate the potential waste taken from these areas in order to assess a quantitative impact of these bad practices.

Early Humboldtian Influences On Alfred Russel Wallace's Scheme Of Nature [Presented At The Alfred Russel Wallace And His Legacy Royal Society Of London Meeting, 21 October 2013], Charles H. Smith

DLPS Faculty Publications

Alfred Russel Wallace’s 1858 Ternate paper on natural selection is a famous work in the history of science. Beyond his co-discovery of the principle, moreover, Wallace is known for a large number of early applications of the idea, both to biological and biogeographical subjects. Yet how much do we really know about Wallace’s own evolution of thought, and his actual intentions before his views were swallowed up by the inertia of Darwin’s revolution? A number of differences between Wallace’s and Darwin’s views are apparent and have been much treated over the years, but related discussions dwell more on effects than …

A Framework To Evaluate Wildlife Feeding In Research, Wildlife Management, Tourism And Recreation, Sara Dubois, David Fraser

Wildlife Population Management Collection

Feeding of wildlife occurs in the context of research, wildlife management, tourism and in opportunistic ways. A review of examples shows that although feeding is often motivated by good intentions, it can lead to problems of public safety and conservation and be detrimental to the welfare of the animals. Examples from British Columbia illustrate the problems (nuisance animal activity, public safety risk) and consequences (culling, translocation) that often arise from uncontrolled feeding. Three features of wildlife feeding can be distinguished: the feasibility of control, the effects on conservation and the effects on animal welfare. An evaluative framework incorporating these three …

Le Nature Degli American Studies, Cindi Katz

Publications and Research

Al “Futures of American Studies Institute” di Dartmouth del 2003 lanciai una provocazione sulle “geografie immaginate” dell’americanistica. Volevo mettere in discussione sia le celebrazioni romantiche del “luogo” in quanto elemento in qualche modo autentico e particolare, minacciato da un mondo sempre più globalizzato e controllato dalle multinazionali, sia l’esaltazione della “delocalizzazione” nelle società in rete, negli “spazi di flusso”, nella mobilità senza attrito. Suggerivo che queste, come altre geografie poco studiate, si sposano troppo facilmente con molte correnti dell’eccezionalismo americano.

Plant Community Composition And Structure Monitoring In Scotts Bluff National Monument, 2013 Annual Report, Isabel Ashton, Michael Prowatzke

United States National Park Service: Publications

Introduction

During the last century, much of the prairie within the Northern Great Plains has been plowed for cropland, planted with non-natives to maximize livestock production, or otherwise developed, making it one of the most threatened ecosystems in the United States. Within Nebraska, greater than 77% of the area of native mixed grass prairie has been lost since European settlement (Samson and Knopf 1994). The National Park Service (NPS) plays an important role in preserving and restoring some of the last pieces of intact prairies within its boundaries. The stewardship goal of the NPS is to “preserve ecological integrity and …

Evaluating Emergency Management After An Event: Gaps And Suggestions, Neil Dufty

Neil Dufty

Post-event evaluations of emergency management are critical to help emergency service providers and communities learn to build disaster resilience. This paper identifies five main types of formal post-event evaluations of emergency management that are used in Australia. It argues that these evaluations should be more consistent in their conduct and approach, more comprehensive in scope, and better timed. The paper also suggests that post-event evaluation reports should be released particularly to the affected communities.

Local Attitudes Towards Bear Management After Illegal Feeding And Problem Bear Activity, Sara Dubois, David Fraser

Wildlife Population Management Collection

The “pot bears” received international media attention in 2010 after police discovered the intentional feeding of over 20 black bears during the investigation of an alleged marijuana-growing operation in Christina Lake, British Columbia, Canada. A two-phase random digit dialing survey of the community was conducted in 2011 to understand local perspectives on bear policy and management, before and after a summer of problem bear activity and government interventions. Of the 159 households surveyed in February 2011, most had neutral or positive attitudes towards bears in general, and supported the initial decision to feed the food-conditioned bears until the autumn hibernation. …

Unnatural Disasters: Rethinking The Distinction Between Natural And Man-Made Catastrophe, Michael D. Cooper, Esq.

Michael D. Cooper, Esq.

The distinction between “natural” and “man-made” disaster has grown increasingly difficult to defend. Our current conception conflates extreme natural events with the notion of disaster—an exclusively human construct. We define our cultural perception of “natural” disaster through three “man-made” constructs. First, our values alone characterize the scope and scale of loss. Second, our volition exacerbates otherwise benign natural hazards, exposes us to otherwise avoidable hazards, and, through technology, generates new and otherwise non-existent hazards. Finally, when natural hazards do unleash their destructive powers, pre-existing socio-economic inequalities manifest as vulnerabilities that ultimately determine both absolute and relative social outcomes and impacts. …

Parental Environments And Interactions With Conspecifics Alter Salinity Tolerance Of Offspring In The Annual Medicago Truncatula, Brenna M. Castro, Ken S. Moriuchi, Maren L. Friesen, Mounawer Badri, Sergey V. Nuzhdin, Sharon Y. Strauss, Douglas R. Cook, Eric Von Wettberg

College of Agriculture and Life Sciences Faculty Publications

Summary: Based on expectations of the stress-gradient hypothesis for conspecific interactions, stress-sensitive genotypes may be able to persist in stressful environments when positive interactions between individuals occur under stressful environments. Additionally, we test how parental environmental effects alter responses to stress and outcomes of conspecific interactions in stress. While the stress-gradient hypothesis focuses on plant growth, earlier flowering may provide stress avoidance in short-lived organisms. We studied responses to soil salinity and conspecific neighbour using genotypes of Medicago truncatula (Fabaceae) originating from saline or non-saline environments, utilizing seeds from parental plants grown in saline or non-saline environments. During the early …

Asphalt Developments: From Road Construction To Environmental Governance And Citizenship In Peru, Sonja Pieck

Sonja Pieck

Peru today is one of the main staging grounds for a continent-wide integration effort. Launched in 2000, the Initiative for the Integration of Regional Infrastructure in South America (IIRSA) calls for an enormous expansion of the continent's transport and energy networks and an effort to increase the region's economic competitiveness. Among its most controversial projects is the Interoceanic Highway linking western Brazil with the Pacific coast of Peru. The highway has attracted fierce criticism from NGOs who point to major environmental impacts, an inadequate mitigation process, and a lack of transparency in funding flows and decision making. In an effort …

Beyond Climate-Smart Agriculture: Toward Safe Operating Spaces For Global Food Systems, Henry Neufeldt, Molly Jahn, Bruce M. Campbell, John R. Beddington, Fabrice Declerck, Alessandro De Pinto, Jay Gulledge, Jonathan Hellin, Mario Herrero, Andy Jarvis, David Lezaks, Holger Meinke, Todd Rosenstock, Mary Scholes, Robert Scholes, Sonja Vermeulen, Eva Wollenberg, Robert Zougmoré

Rubenstein School of Environment and Natural Resources Faculty Publications

Agriculture is considered to be "climate-smart" when it contributes to increasing food security, adaptation and mitigation in a sustainable way. This new concept now dominates current discussions in agricultural development because of its capacity to unite the agendas of the agriculture, development and climate change communities under one brand. In this opinion piece authored by scientists from a variety of international agricultural and climate research communities, we argue that the concept needs to be evaluated critically because the relationship between the three dimensions is poorly understood, such that practically any improved agricultural practice can be considered climate-smart. This lack of …

《跨边界资源管理》书评, Luc Changlei Guo

Luc Changlei Guo

In discussing theoretical and analytical issues relating to cross-border resource management, this book explores a group of geographical, political, legal, economic and cultural factors that arise when political units (such as sovereign countries, dependent states and other administrative units) seek to maximize their political and economic interests while minimizing the resultant damage (e.g. resource degradation and preservation of the physical environment). The book is organized into three parts. Part one discusses the theoretical issues relating to cross-border development and the cross-border management of natural and environmental resources. Part two provides a variety of alternatives to advancing cross-border development as well …

Climate Change And Human Rights: A Case Study Of Vulnerability And Adaptation In Coastal Communities In Lagos, Nigeria., Idowu M. Ajibade

Electronic Thesis and Dissertation Repository

Lagos, Nigeria is one the world’s megacities at risk from climate change. Communities along the coast have been hit hard by floods, storm surges, and rising seas, due to the city’s geographic location, inadequate infrastructures, and poor urban governance. These factors together with social inequality have been known to shape vulnerability to climatic hazards but less understood is the role of human rights.

The objective of this thesis is to develop a grounded understanding of the links between human rights and the vulnerability of people to climate change impacts (i.e. floods and storm surges). The study combined qualitative and quantitative …

Plain & Simple: The Will To Live Sustainably In An Unsustainable World, Brandi Nichole Button

Masters Theses & Specialist Projects

Sustainability is a buzzword covering a variety of fields and subjects. For the purposes of my research sustainability is “the ability to keep going over the long haul. As a value, it refers to giving equal weight in your decisions to the future as well as the present” (Gilman 1). The sustainability movement refers to activists, educators and researchers who are dedicated to finding high quality ways of living in the world that are environmentally benign for all who are now living as well future generations to come (Gilman 1). This research focuses on three women who engage in voluntary …
