Product Stewardship In Health Care: The Importance Of Minimising The Environmental And Health Impacts Of Plastic Products, Kerstin Wyssusek, Mahalakshmi Avudainayagam, Jayne Paramor, Leonie Barner

Journal of Perioperative Nursing

Increased waste in health care is a widespread problem. Currently, modern clinical practices favour single-use products and pre-packaged supply kits. Many of these consist of various types of plastics. By weight, up to 25 per cent of total hospital waste is plastics. Common plastics used are polyethylene terephthalate, polypropylene, polyethylene, polyvinylchloride and polyurethane. Polyethylene terephthalate represents the highest volume, and accounts for 40 per cent of the plastics used in operating rooms.

Health care has an enormous ecological footprint. Around the world, health care waste management strategies and clinician activities are starting to address how health care affects our planet …

Purchasing Choices That Reduce Climate Change: An Exploratory Factor Analysis, Yuhan Bi, Kimberly Barchard

Spectra Undergraduate Research Journal

Household consumption is a primary source of green-house gas emissions. Individuals can substantially reduce their climate impact by making sustainable purchasing choices, such as choosing products that are made locally and have less packaging, buying used, repairing items rather than replacing them, supporting libraries and bike-share programs, encouraging others to buy less, and donating to charity in someone’s name rather than buying gifts. The Climate Change Action Inventory measures the frequency of 77 daily behaviors, including 14 items regarding Climate-Friendly Purchasing Choices. The purpose of this research was to determine if purchasing choices could be divided into meaningful factors. We …

Objective Indicators For Monitoring Drought In Grasslands, D H. White, S M. Howden

IGC Proceedings (1997-2023)

Australia’s National Drought Policy was ratified by the Commonwealth (Federal), State and Territory governments in 1992. However, a sequence of El Niño-based events that started in Queensland in 1991 culminated in much of Australia experiencing abnormally low rainfall throughout 1994 and into 1995. Many farmers experienced substantial loss of income. The Commonwealth government therefore devised measures to determine which areas had been exposed to exceptional drought so that financial assistance could be directed as effectively as possible. In this paper we discuss progress in developing regionally-sensitive indicators and methodologies to aid in future assessments of drought exceptional circumstances.

Production V Conservation: A Policy Dilemma In The Tree Clearing Debate In Queensland, Australia, J C. Scanlan, E J. Turner

IGC Proceedings (1997-2023)

A process for developing policy for tree clearing that meets the competing goals of conservation and production has been followed. There were two levels at which policy was developed. An overall Statewide policy outlined general targets to meet commitments of the Queensland Government. Local guidelines were developed by a large number of groups containing representatives of government and interested conservation movement and industry representatives. The policy and the local guidelines are an important part of the process used to assess applications for permits to clear woody vegetation.

Sustainable Grazing Systems- A Program To Develop And Deliver Improved Temperate Pastures In Australia, W K. Mason, G Kay, G Lodge

IGC Proceedings (1997-2023)

The Sustainable Grazing Systems Program aims to combine the efforts of producers, researchers and extension agents into a focused partnership to develop, manage and implement grazing systems that are more profitable and more sustainable. Rather than the traditional approach of undertaking the research and then developing extension packages for livestock producers, this Program has set up a network with producers, researchers and extension agents to collectively develop and test improved systems. The process is described as colearning. Compared with more traditional approaches, producer input is greatly increased as the role of researchers and extension agents is modified, but not decreased. …

Legume-Legume Complementary For Sustainable Pasture Development In The Tropics, M Peters, S A. Tarawali, R Schultze-Kraft, A Musa

IGC Proceedings (1997-2023)

The use of legume-legume mixtures to alleviate limitations of individual species in legume based technologies was investigated in subhumid Nigeria. The results indicate the potential of legume mixtures, through processes of complementation and compensation, to reduce the risk of legume establishment and survival and thus ensure sustainable legume yields and percentages. The implications for on-farm adoption of forage legumes are discussed.

Principles Of Tree Management In The Grazing Lands Of Queensland, Australia, J C. Scanlan, E J. Turner

IGC Proceedings (1997-2023)

The key factors that influenced the appropriateness of clearing were identified for Queensland. The first stage was to identify endangered and vulnerable vegetation types, with final agreement being that clearing would not be undertaken in these regional ecosystem types. For other regional ecosystems, the degree of clearing that was appropriate was determined from the original and current extent of that ecosystem type, the sustainability of any development and any off-site effects of clearing. The maximum slope suitable for clearing, the width of riparian buffers and other corridors were also determined. These local guidelines for tree clearing became a central part …

Long Term Benefits Of Diversified Forage-Oriented Cropping Systems As Compared To Rotations Based Mainly On Cereals Or Maize, E Meister, V Mediavilla, P Weisskopf

IGC Proceedings (1997-2023)

The aim of this study is to assess the long term effects of a forageoriented, versus a maize- and a cereal-oriented crop rotation on the yield potential and soil fertility, as well as the weed, disease and pest development. We report the results after four cropping cycles using silage maize (Zea mays L.) in 1994 and winter wheat (Triticum aestivum L.) in 1995 as reference crops for all three rotations. Two years of a grass-clover mixture in a five-year rotation showed positive effects with respect to most soil and plant parameters.

Island-Wide Characterization Of Agricultural Production Challenges The Demographic Collapse Hypothesis For Rapa Nui (Easter Island), Dylan S. Davis, Robert Dinapoli, Gina Pakarati, Carl P. Lipo

Anthropology Faculty Scholarship

Communities in resource-poor areas face health, food production, sustainability, and overall survival challenges. Consequently, they are commonly featured in global debates surrounding societal collapse. Rapa Nui (Easter Is- land) is often used as an example of how overexploitation of limited resources resulted in a catastrophic popula- tion collapse. A vital component of this narrative is that the rapid rise and fall of pre-contact Rapanui population growth rates was driven by the construction and overexploitation of once extensive rock gardens. However, the extent of island-wide rock gardening, while key for understanding food systems and demography, must be better understood. Here, we …

Grassland Management For Geese: Sustainable Use For Conservation And Agriculture, S M. Percival, R Lilley

IGC Proceedings (1997-2023)

Increasing numbers of overwintering wild geese have caused considerable problems to agriculture but are often also of conservation concern as their populations are relatively small. Islay, Scotland, is one site where this problem is particularly acute. We studied the two goose species which use this site, the barnacle goose, Branta leucopsis, and the white-fronted goose, Anser albifrons flavirostris, and found that they preferred younger pastures located closer to their roost sites. These preferred areas could be important in developing a sustainable strategy for future goose management. Further non-sustainable population increases might be avoided by increasing disturbance in these areas.

The Middle East: From An Inflammable Region To A Resilient Land Of Opportunities–A Case Study Of Ecopeace Middle East's Approach To Conflict And Environmental Action, Yana Abu Taleb, Thalsa-Thiziri Mekaouche

New England Journal of Public Policy

The Middle East is an inflammable region on multiple levels. The ongoing war between Israel and Hamas, with its overwhelming loss of human lives, has further disrupted the already fragile prospect of peace in the region. It is also ‘inflammable’ from an environmental perspective, insofar as it is considered the most climate vulnerable region on Earth, with an expected 4°C increase in average temperature over the next decades. Yet, through the example of EcoPeace Middle East, an environmental and peacebuilding regional organization working in Jordan, Israel, and Palestine, this article sheds light on a theory of change that seeks to …

The Relationship Between Culture, Sustainable Use Of Resources, And Financial Performance: An Institutional And Natural-Resource-Based Perspective, Deon H. Engelke, Noel J. Pearse, Fabio M. Correa, Frederick O. Skae

Economic and Business Review

Modelling a dataset of 5230 globally listed firms through two statistical approaches reflecting the primary principles of Natural-Resource-Based Theory and Institutional Theory, respectively, this study provides evidence that sustainability initiatives developed by firms are being rewarded in the form of improved Corporate Financial Performance (CFP). Culture has a significant influence on both firm sustainability performance, captured in ESG ratings, and CFP and also interacts with other variables, including industry sector and socio-economic development of a firm’s markets. This study is unique in hypothesising and statistically proving that sustainability is a mechanism that activates the potential of culture to produce CFP. …

Product Design For Repairability: Identifying Failure Modes With Topic Modeling And Designing For Electronic Waste Reuse, Claire J. Franz

Master's Theses

Design for repairability is imperative to making products that last long enough to justify the resources they consume and the pollution they generate. While design for repairability has been gaining steady momentum, especially with recent advances in Right to Repair legislation, there is still work to be done. There are gaps in both the tools available for repair-conscious designers and the products coming onto store shelves. This thesis work aims to help set sails in the right direction on both fronts.

This research explores the use of topic modeling (a natural language processing technique) to extract repairability design insights from …

How Reuse Rooms Can Reduce Waste On University And College Campuses, Zoe Slabodnik

University Honors Theses

This undergraduate honors thesis discusses the importance of how reuse rooms on university and college campuses can reduce waste by providing an alternative method of disposal other than landfills. There is currently no definition in use that exists for the term reuse room. This thesis defines a reuse room as a community room where anyone with access can donate and take free items that can be reused, recycled, repurposed, repaired and reworn. The goal of a reuse room is to encourage waste reduction, promote and destigmatize the use of second-hand materials, and save money and items from going to landfills. …

Repair Rolodex: Exchanges, Changes, And Patchwork Parables, Ethan Howard

Masters Theses

This book is an index of nine exchanges with strangers whom I met online through email Listservs or by word of mouth. In these transactions, I offered to repair broken things for a trade-in-kind payment. Through the brief relationship between owner and designer, each interaction suggests that an object is almost never entirely obsolete despite its perceived obsolescence.

At the core of these trades is a grassroots protest of the landfill and a critique of our global capitalist commerce system. The apparent desire for and nature of these trades demonstrates that stories make our objects meaningful. Each interplay studies peoples’ …

Bikeability Disparities In Orange County, California: Intersection Of Place And Demographics, Jeanette Gritton, Maria Cristina Martinez, Georgiana Bostean, Megan Thiele Strong

Sociology Faculty Articles and Research

Active transportation modes such as walking and biking are gaining popularity for their extensive health and environmental benefits, yet scholars know little about how place-based accessibility varies by area sociodemographic composition. This study is among the first to examine sociodemographic disparities (by both race and socioeconomic status) in bikeability while allowing for heterogeneity in disparities. Consideration of bikeability disparities is particularly critical within the framework of urban planning concepts that promote equitable accessibility and reduced dependency on automobiles, such as the 15-minute city. Geographically Weighted Regressions examined associations between census tract-level bikeability (using an index that combines five components), socioeconomic …
