As urbanization grows wildlife habitat is displaced and fragmented. Vegetative roofs offer an innovative alternative to provide animal food and habitat in urban environments. This research study investigates how wildlife needs in a green roof ecosystem are interpreted through children’s visual perception. A visual preference survey was administered to fourth-grade students in Starkville, Mississippi which offered paired photographs displaying basic vertebrate and invertebrate needs. The responses from 85 students (n=85) were compared to identify preferences for legible habitat components. The results of this survey showed that fourth-grade students could readily identify the basic habitat needs for birds but were less able to with insects. Students were intrigued with utilizing a green roof for learning and play. Green roofs have potential to be designed as innovative teaching tools to enhance science education in K-12 schools.

Traditional trails near backcountry stream corridors are often designed with disregard to their potential ecological impact. Ecological and trail related literature show that riparian landscapes are sensitive to recreation impacts. This thesis examines concepts for designing trails in ecologically compatible ways near backcountry stream corridors. The synthesis of the literature regarding the biophysical processes of stream corridors and the effects of trails on the environment is used to help develop principles and guidelines for locating trails near backcountry stream corridors. In turn, these principles and guidelines assisted in the development of a trail assessment manual useful to scientists, planners, and designers. Seven trail impacts are assessed: excessive soil erosion, wet trails, water on trails, excessive trail widths, multiple trails, root exposure, and stream sedimentation. Three backcountry study sites from the Appalachian Ridge and Valley Province of Virginia are evaluated. A ranking and measurement procedure is developed to characterize environmental, use, design/siting, construction, and maintenance factors because each of these influence the degree of impacts along studied trails. Results show that many steep trail segments, especially those without proper drainage features have incised or eroded trail treads. Likewise, many trail segments without drainage features located along flat adjacent landforms have wet soil and water on trail impacts. Overall results show that as use amount or type increase there is a parallel in trail and environmental degradation. Finally, a stream crossing and trail drainage concept is developed illustrating ways to reduce sediment inputs into nearby streams. / Master of Landscape Architecture

The loss of ecological integrity as a result of urban spread and construction threatens the overall biodiversity of urban areas and prompts us to consider means of better including ecological biodiversity within development projects. The UK’s best practice tool for ensuring the integration of ecology into such projects is the Building Research Establishments Environmental Assessment Method (BREEAM). This thesis seeks to identify the efficacy of the current approach to ecological integration within BREEAM, and enable development to foster biodiversity and ecology more positively in the urban environment. Qualitative and quantitative research techniques were used to develop a new approach to the integration of ecology within an existing and nationally recognised model. This began by exploring the efficacy of and the main flaws in the present system by a survey of ecologists with experience of the BREEAM process. This led to a new approach to establishing the ecological value of urban ecology utilising a new calculation methodology, adapting the current scheme to focus on land use change as a result of urban land use planning and development. This new approach utilises habitat changes at its core to measure positive and negative change and indicate potential design solutions in land use planning within a development. The innovative methodology was tested using an in depth case study to review and discuss its effective application. The outcome was a new way to address the important variables of habitat integration and linkages maintaining ecological integrity and provision of ecosystem services. It is considered that the outlined approach of the new Land Use and Ecology section of BREEAM is suitable for integration into the next iteration in 2010, which will enable development to positively foster biodiversity and ecology in the urban environment.

Organic waste management presents challenges and opportunities alike for community-based economic development. Waste-to-compost transformation can be socially and economically successful by employing ecological design principles, multi-stakeholder collaboration, and values-based supply chains (VCs). An analysis of commercial buyers' preferences for compost will inform approaches to forming effective partnerships of public, private and nonprofit stakeholders to develop a market for local waste resource products. The thesis summarizes the results of a consumer preferences survey of current and prospective bulk compost purchasers and discusses strategies for implementing new organic waste management policies that will strengthen a local market for compost, build social capital and share economic value. A conjoint analysis of bulk compost preferences in Vermont was conducted to identify the market's preference for quality-based attributes of bulk compost. The data was taken from a survey administered by mail to Vermont business professionals in various fields that use--or could potentially use--compost products in providing goods or services. In addition to price (81 percent of the relative importance buyers place on an attribute), local provenance (8 percent) and suitability for organic production (7.6 percent) were demonstrated as statistically significant determinants of the value buyers placed on compost. Willingness to pay for local provenance and suitability for organic production were measured at 15% and 14% above the baseline product price, respectively. Current and prospective compost producers can effectively market their products and retain a competitive edge in the marketplace by collaborating with other businesses. A viable market for Vermont compost could be achieved through cultivation of niche specialties, stable institutional buyers, more stringent regulation of food waste and nutrient management behavior, and a collaborative effort to construct a product narrative that emphasizes compost's role in a larger social-ecological system of nutrient management and sustainable agriculture.

Human culture has recognized the damage being caused to our environment and is in the process of transitioning toward sustainable systems. Design disciplines and environmental studies are engaging in alternative ways to support a sustainable world and, to a large extent, on resolving the disconnection between humans and nature. The conceptualization of <i>Symbiotic Design</i> proposed in this research, facilitates theoretical-practical reflections and recognizes that learning through closer association with the natural world can trigger innate responses and enhance human creativity. Designers need to have an understanding of these concepts to allow them to design in an ecologically conscious way. Using biophilia, biomimicry and resilience thinking as core eco-techniques, the research develops a series of teaching/learning practices that aim to enhance the embodiment of design with-in nature. This <i>Symbiotic Design</i> Practice process was developed, tested and evaluated across a sample of undergraduate and postgraduate design students. Text, visuals and workshop activities evolved through a method of action-based cycles. In essence, the research proposes a new eco-pedagogical strategy that facilitates nature-based experiences and behavior change toward an ecologically conscious design culture.

This work is part of a wider personal and eco-cultural wondering about how to restore and conserve the pleasure of living aligned with the ecology of life. There is a growing concern that one of the biggest challenges we have is to generate sustainable communities. Based on this, the research particularly deals with the following two questions: What is ecological design? And, how does Ecological Design both emerge from, and contribute to, the constitution and conservation of human sustainable communities in our Western-European culture? The research proposes that the only way to understand the practice of ecological design is by dealing with the broader dynamics of human ecology—or, ultimately with what it means to be a human being. Based on a systemic, interdisciplinary and multidisciplinary approach, the research first explores the phenomenological and bio-cognitive dynamics that generate an ongoing, embodied–ecological epistemology of the human-Nature relationship, thereby overcoming the modern dualism of mind-body and man-nature. It suggests that design ineluctably takes place in this embodied-ecological domain—particularly, in an ongoing eco-cultural network of interactions. Then it explores the emotional basis of human intentionality and behaviour and, based on the work of the biologist Humberto Maturana, proposes that human beings exist in a dynamic interweaving of languaging and emotioning in an eco-cultural medium. This is synthesized through the notion of conversation. The research claims that to design is to converse. Based on this, the research then explores biological and philosophical accounts of the emotion of loving. By exploring basic elements of a synthesis of the ecology of loving, the research suggests that this emotion is the only one that allows the emergence and cultivation of intimate socio-ecological relationships. Accordingly, it also argues that loving is the foundation of environmental ethics and ultimately, the practice of ecological design. The research also explores the conscious sense and practice of homing (or home-making). It argues that homing and loving are interdependent; they form a circular causality—homing-in-love. The research suggests that homing-in-love is what we do when we design ecologically. Finally, the research explores a general framework that may contribute to the process of recovering the vital dynamics of homing-in-love in a global age. In a four-month ethnographic investigation of three Western-European ecovillages, the research explores particular designed platforms of conversation as examples of the practice of ecological design from which more sustainable manner of homing are emerging and being cultivated.

There has been a notable interest in landscape design in the recent years. Growing environmental consciousness and the deindustrialization process in cities have resulted in the new park design projects which have been created through recovery of waste lands. The thesis examines a number of selected park projects with two frameworks which are the reclamation methods and the design strategies. The reclamation methods constitute the ways of recovering wastelands / while, the design strategies constitute the design approaches and methods used in these projects at urban scale. The contemporary approaches to park design are studied in the thesis, in three parts which are &#039 / &#039 / the strategic design&#039 / &#039 / , &#039 / &#039 / the place-based design&#039 / &#039 / and &#039 / &#039 / the ecological design&#039 / &#039 / . Two proposals of the Parc de la Villette competition, Parc Andr&eacute / Citro&euml / n, Bercy, Invaliden, Downsview, Fresh Kills and High Line parks are the cases studied. A categorization of the approaches was done according to the design concepts of the projects. Strategic design comprises the projects conceived in a way that would adapt to future conditions / place-based design covers the projects designed by referring to the meanings derived from their sites with the aim to maintain or create a sense of place / and finally ecological design cover projects which were designed to sustain and diversify the ecological values of their sites. The examination of three types of park design approaches does not propose a strict categorization / but rather it displays continuities in the evolution of park designs. The design concepts, strategies and tools, besides the working principles and innovative aspects of these approaches are studied in a comparative way. The thesis is concluded with an evaluation of the new significances of landscape design.

The current human-created division between the natural and built environments has exacerbated environmental problems because nature has been designed as and, consequently, is seen as an Other to be utilized and manipulated at will. Exploring this disconnected relationship between humans and nature, as well as its origin and its effect on building occupants and the environment, is thus a necessary part of this project. The primary concern, however, centers on how we can establish a relationship with the natural environment through interior design to help foster ecological design practices and positive environmental behaviors that move beyond sustainability, resulting in a positive human-nature relation while supporting a coevolutionary perspective. Specifically, this investigation utilizes biophilic design as a solution to the division. The product is an adaptively reused structure that houses a mixed-use, multi-unit residential development, which explores the creation of human-nature connections through direct, indirect, and symbolic means.
