Fire And The Invasive Annual Grass Microstegium Vimineum In Eastern Deciduous Forests, S. Luke Flory, Keith Clay, Sarah Emery, Joseph Robb

JFSP Research Project Reports

Non-native plant invasions have the potential to change natural and prescribed fire regimes by increasing fuel loads, continuity of fuels, and fuel composition, which may alter fire intensity, damage native species, and promote further invasions. In this project we sought to evaluate the interaction between fire and the invasive annual grass Microstegium vimineum in eastern deciduous forests. Our goal was to determine if invasions enhance fire intensity, including fire temperatures, flame heights, and fire duration, and negatively affect tree regeneration, and stimulate further invasions. We also sought to determine how prescribed fires and the timing of fires affect the density …

Identification Of Necessary Conditions For Arctic Transport Of Smoke From United States Fires, Narasimhan K. Larkin, Jennifer L. Dewinter, Tara M. Strand, Steven G. Brown, Sean M. Brown, Sean M. Raffuse, Jonathan Callahan, Kenneth J. Craig, Robert C. Solomon, Hilary R. Hafner

JFSP Research Project Reports

The deposition of black carbon (BC), a dark absorbing aerosol, is a significant contributor to observed warming trends in the Arctic (Hansen and Nazarenko, 2004; Jacobson et al., 2007). Biomass burning outside of the Arctic, including wildland prescribed fires, is a major potential source of Arctic BC. Therefore, limiting or eliminating spring prescribed burning has been suggested to Congress as a BC reduction technique (e.g., Zender, 2007). However, there are large uncertainties in the current estimates of the sources, source regions, and transport and transformation pathways of BC transported to the Arctic region (Shindell et al., 2008; Hegg et al., …

Florin C MIHAI

This paper analyzes the expansion of sanitation services in rural areas after the closure and rehabilitation of rural dumpistes having as deadline July 16, 2009. Following this period local authorities are forced to collect and dispose the waste generated in urban landfills from proximity until the transfer stations will be operational. Most of the rural population has no access to waste collection services, waste generated and uncollected are uncontrolled disposed polluting the local environment. Development of sanitation services is a basic condition for an efficient implementation of integrated waste management system at county level.

David J. Muth

Economic analyses on the viability of corn (Zea mays, L.) stover harvest for bioenergy production have largely been based on simulation modeling. While some studies have utilized field research data, most field-based analyses have included a limited number of sites and a narrow geographic distribution. An Iowa case study is developed illustrating the use of data extracted from a database of geographically distributed field studies for a region-specific economic analysis. The analysis utilizes grain and residue yield and associated management information from two Iowa field research sites that are Sun Grant Regional Partnership locations associated with the Corn Stover Regional …

High Speed Rail In America: An Evaluation Of The Regulatory, Real Property, And Environmental Obstacles A Project Will Encounter, Darren A. Prum, Sarah L. Catz

Darren A. Prum

In 2009, President Barak Obama allocated $8 billion in stimulus funding for high speed rail projects across the United States. One year later, in 2010, an additional $2.5 billion was distributed to corridors with High Speed Rail Projects. Even though the most recent congressional budget eliminated high speed rail funding, many corridors are working diligently to break ground by the end of 2012. Before a high speed rail project can be fully implemented there are many legal and environmental issues and regulations to examine. This paper conducts a complete analysis of those issues and regulations and suggests how to apply …

Urban Ecosystem Services: Tree Diversity And Stability Of Tropospheric Ozone Removal, Fausto Manes, Guido Incerti, Elisabetta Salvatori, Marcello Vitale, Carlo Ricotta, Robert Costanza

Institute for Sustainable Solutions Publications and Presentations

Urban forests provide important ecosystem services, such as urban air quality improvement by removing pollutants. While robust evidence exists that plant physiology, abundance, and distribution within cities are basic parameters affecting the magnitude and efficiency of air pollution removal, little is known about effects of plant diversity on the stability of this ecosystem service. Here, by means of a spatial analysis integrating system dynamic modeling and geostatistics, we assessed the effects of tree diversity on the removal of tropospheric ozone (O3) in Rome, Italy, in two years (2003 and 2004) that were very different for climatic conditions and ozone levels. …

Building A Sustainable And Desirable Economy-In-Society-In-Nature, Robert Costanza, Gar Alperovitz, Herman E. Daly, Joshua C. Farley, Carol Franco, Tim Jackson, Ida Kubiszewski, Juliet Schor, Peter A. Victor

Institute for Sustainable Solutions Publications and Presentations

This report is a synthesis of ideas about what this new economy-in-society-innature could look like and how we might get there. Most of the ideas presented here are not new. The coauthors of this report have published them in various forms over the last several decades, and many others have expressed similar ideas in venues too numerous to mention. What is new is the timing and the situation. The time has come when we must make a transition. We have no choice. Our present path is clearly unsustainable. As Paul Raskin has said, "Contrary to the conventional wisdom, it is …

Institutions For Managing Ecosystem Services, Jennifer H. Allen, Jenny Duvander, Ida Kubiszewski, Elinor Ostrom

Institute for Sustainable Solutions Publications and Presentations

Two decades of research into the management of what economists call common-pool resources suggests that, under the right conditions, local communities can manage shared resources sustainably and successfully. These revolutionary findings challenge the long-held belief in the "tragedy of the commons." Instead, we have found that tragedy is not inevitable when a shared resource is at stake, provided that people communicate. In many places—from Swiss pastures to Japanese forests—communities have come together for the sake of the environment and their own long-term well-being. Common-pool resources have two features: first, they are shared resources whose use by one person makes them …

Institute for Sustainable Solutions Publications and Presentations

Iowa is a leader in crop and livestock production, but its high productivity has had concomitant negative environmental and societal impacts and large requirements for fossil-fuel-derived inputs. Maintaining agricultural productivity, economic prosperity and environmental integrity will become ever more challenging as the global demand for agricultural products increases and the resources needed become increasingly limited. Here we present four scenarios for Iowa in 2100, based on combinations of differing goals for the economy and differing energy availability. In scenarios focused on high material throughput, environmental degradation and social unrest will increase. In scenarios with a focus on human and environmental …

Ecosystem Health And Ecological Engineering, Robert Costanza

Institute for Sustainable Solutions Publications and Presentations

Ecosystem health is a desired endpoint of environmental management and should be a primary design goal for ecological engineering. This paper describes ecosystem health as a comprehensive, multiscale, measure of system vigor, organization and resilience. Ecosystem health is thus closely linked to the idea of sustainability,whichimplies theabilityofthesystemtomaintainits structure(organization)andfunction (vigor) over time in the face of external stress (resilience). To be truly successful, ecological engineering should pursue the broader goal of designing healthy ecosystems, which may be novel assemblages of species that perform desired functions and produce a range of valuable ecosystem services. In this way ecological engineering can achieve its …

This article analyzes the institutional framework that undergirds efforts in Seattle, Washington to normalize the production and use of edible landscapes. We focus attention on the role of grassroots fruit gleaning groups and highlight their bridging function between Seattle's agriculture and forestry policy …

Corporate Accountability: A Path-Goal Perspective, Nancy E. Landrum, Cynthia M. Daily

School of Environmental Sustainability: Faculty Publications and Other Works

Corporations are increasingly seeking corporate accountability. There have been a growing number of principles, standards, measurement tools, and guides for reporting, stakeholder engagement, and assurance to aid corporations; many of which are discussed here. Yet corporations are faced with a confusing array of competing protocols and a complex challenge in defining how to navigate the process to improve accountability. Path-goal theory offers a perspective which allows us to present a simplified 3-step path to guide corporations. However, path-goal theory also reveals problems inherent in the current approach, namely, an ambiguous situational context and lack of leadership that is directive, task-oriented, …

An Integral Theory Perspective On The Firm, Nancy E. Landrum, Carolyn L. Gardner

School of Environmental Sustainability: Faculty Publications and Other Works

We propose that Ken Wilber’s (2000) integral theory can serve as a new paradigm by which to view the organization and present a broader view of the roles and responsibilities of business. Through an integral theory of the firm, we see individual desires, capabilities and limitations, economic profit and humanitarian interest working in synergy to maximize firm performance. This holistic approach is innovative and is presented as a way to redefine the existence, boundaries, and organization of the firm and to show how organizations can become more ecologically sustainable, socially responsible, and economically competitive. An integral theory of the firm …
