This study assesses whether multifunctional edible landscaping business models provide a sufficient business case at enterprise and city scales to justify widespread implementation. First, semi-structured interviews were conducted with four landscaping entrepreneurs, and the information obtained from the interviews was utilized to carry out a business model comparison with the Business Model Canvas framework. The comparison showed that the landscaping enterprises using multifunctional edible landscaping methods possessed a greater range of value propositions and revenue streams, enhancing their competitive advantage. Second, a GIS landscape analysis of seven Phoenix metro area cities was carried out to identify landscapes that were suited for becoming multifunctional edible landscapes. The GIS analysis identified single family residential, residential recreational open space, municipal parks, and municipal schools as being suitable landscapes, and that the area of these landscapes in the seven cities exceeded 180,000 acres. Third, scenarios were created using interview and GIS data to estimate potential value creation and return on investment of implementing multifunctional edible landscaping in the cities of interest. The scenarios found that the potential value creation of edible landscaping ranged between $3.9 and $66 billion, and that positive return on investment (ROI) could be achieved in 11 out of 12 scenarios within one to five years. Finally, the paper concludes by discussing potential long-term implications of implementing multifunctional edible urban landscaping, as well as possible future directions for multifunctional landscaping business model development and research.
Marine harvesters face significant livelihood challenges due to the impacts of climate change on marine ecosystems, and due to economic fluctuations that influence their incomes. In this study, we demonstrate vulnerability as a product of the interactions among marine harvesters, government and buyers. We combined Elinor Ostrom's attention to the influence of institutions on resource exploitation, with political ecology's attention to perceptions of agency, and the contribution of justice and equity to measuring the success of institutions. We demonstrate the benefits of this approach by examining the multi-species fishery of Barrington, Nova Scotia. We conducted 31 semi-structured interviews and 113 surveys in the summer of 2012 with buyers, harvesters, and local experts. We used Ostrom's SES framework to pinpoint system elements that were salient to respondents, with attention to household vulnerability outcomes.
Based on an analysis of these themes, we outline three processes affecting vulnerability outcomes: 1) Harvesters preferred individual over collective action due to low procedural justice and social cohesion in decision-making, 2) agents with greater political and economic power gained control over fishing access-rights while others became more dependent on lobster, and 3) economic and ecological conditions, combined with increased dependence, incentivized harvesters to catch more lobsters as prices declined. The case suggests that actors sense of control over their resource base and perception of justice in the process of institutional design may be as significant in vulnerability as the exogenous drivers of change that affect livelihood outcomes. We suggest interventions that may improve these interactions among government, harvesters and buyers, and improve the livelihoods in coastal communities.
Just prior to the green revolution, Indian wheat scientists adopted Borlaug’s new plant breeding philosophy—that varieties should have as wide an adaptation as possible. But Borlaug and Indian wheat scientists also argued that wide adaptation could be achieved by selecting only plants that did well in high fertility and irrigated environments. Scientists claimed, in many cases erroneously, that widely adapted varieties still produced high yields in marginal, or resource poor, areas. Many people have criticized the green revolution for its unequal spread of benefits, but none of these critiques address wide adaptation—the core tenant held by Indian wheat scientists to justify their focus on highly productive land while ignoring marginal and rainfed agriculture. My dissertation describes Borlaug and the RF's research program in wide adaptation, Borlaug's involvement in the Indian wheat program, and internal debates about wide adaptation and selection under favorable environments among Indian scientists. It argues that scientists leveraged the concept of wide adaptation to justify a particular regime of research focused on high production agriculture, and that the footprints of this regime are still present in Indian agriculture.
The widespread environmental degradation characterizing the Anthropocene is a call to address a deteriorating human-nature relationship. For much of history, humans have been deeply connected with and in respect of nature both physically and psychologically, and this bond can be renewed. Doing so is especially important for future generations, as modern youth have less opportunities to experience the natural world and more opportunities to experience the virtual world. A lack of nature connectedness in our youth has clear implications for sustainability and underscores the need for interventions aimed at reconnecting youth with nature. Primary and secondary education is a particularly valuable leverage point for such interventions, and nature-based school landscapes may be a valuable tool in strengthening the human-nature relationship and reconnecting youth with nature. While studies have indirectly linked garden-based learning and connection with nature in youth, research has not yet directly explored the relationship between the two.
My research explores 12th grade students attending Desert Marigold School in South Phoenix. Desert Marigold practices Waldorf educational philosophy with the school’s garden as a primary teaching tool and recreational space. I used arts-based methods to give students an opportunity to visually communicate their perspectives of the school’s landscape through photography and artistic renderings. Students then verbally described and discussed their media in a series of group interviews. Data were then coded and analyzed for themes of connection with nature expressed in the literature. The results illustrate that students connect with nature in a variety ways through the school’s landscape, demonstrating potential for enhanced sustainability outcomes in education.
Globally we are struggling to match the need for development with the available resources. Kate Raworth’s (2012) developed the idea of a “safe and just space” as a balance between the planetary boundary approach and ensuring a level of basic needs satisfaction for everyone. O’Neill et al. (2018) argue that countries are currently not able to provide their populations with basic needs without concurrently exceeding planetary boundary measures. While attempts have been made to get people to change their habits through moral self-sacrifice, this has not been successful. Kate Soper (2008) argues that a change towards sustainability will only be possible if an alternative to high consumption is offered, without trade-offs in well-being. Technological improvements are often thought to end up providing solutions to the problem of overconsumption, but as Jackson (2005) shows convincingly, this is highly unlikely due to the overwhelming scale of changes required.
‘Alternative hedonism’ (Soper 2008) is a philosophical approach that has been proposed to solve this dilemma. By changing what humanity pursues to be less focused on consumption and more linked to community interaction and living healthy, fulfilling lives, we would simultaneously reduce stress on the globally limited resources and sinks. By developing and understanding satiation points – the point beyond which well-being no longer increases because of increased consumption - affluence that wastes resources without improving well-being could be reduced. This paper explores how ‘alternative hedonism’ and the development of ‘satiation points’ could be helpful in getting humanity closer to the ‘safe and just space’. The paper concludes with a discussion of some of the challenges that taking up of ‘alternative hedonism’ would entail.
Most urban agriculture sites experience challenges related to sustainability, but in the Sonoran Desert, even more challenges arise as a result of a unique climate, soil conditions, intense storms, and water scarcity. The objective of this project was to obtain information on common barriers to urban agriculture in the Sonoran Desert, as well as ways to overcome these barriers that will be made public for the purpose of improving sustainability of similar agriculture projects. I used interviews with gardeners and farm staff as my primary research method to gain insight to these barriers and solutions, and I coded their responses relating to challenges according to frequency mentioned. Using my findings, I compiled a thorough list of recommendations that urban agriculture projects in the Sonoran Desert or in similar climatic areas can use to achieve greater success and sustainable outcomes.
