Zero food waste city 2049: Identifying barriers to transition pathways Daniel Black, Ian Roderick, Adina Paytan, Sue Charlesworth and Joy Carey from an Urban Living Lab in the UK have tested newly integrated systems approaches and valuation methods to understand how to reduce the city's food waste. Food waste costs the UK billions of pounds each year and much of it is avoidable. The challenge for the WASTE FEW ULL research project was to produce and test methods for identifying inefficiencies in the food-energy-water (FEW) nexus in urban settings. Looking in particular at Bristol city, which throws away 48,000 tonnes of food waste each year, the team looked into how they could transform Bristol into a sustainable food city. Stakeholder concerns arose including the nutrient overload problem in water systems and the economic recovery of phosphate; the large amount of food waste from the city linked to food security issues; the energy and carbon footprint of the digestate produced from the anaerobic digestors; the economic challenges of reducing food waste; the plastic contamination of waste streams; sewage system blockages; and the difficulties of recycling sewage and wastewater. This research looks at the challenge of phosphorous recapture from sewage through extensive discussions agreed to shift the project focus to residential food waste reduction and processing (and the associated plastic contamination). The team eventually began looking at the critical concept of resilience and economic efficiency, working to substantially reduce inefficiencies in a city-regions FEW nexuses.

Sustainable urban systems and just FEW nexus transitions
Sustainable urban systems and just FEW nexus transitions Water, food, and energy systems are providing fundamental services for human wellbeing. However, the current management of these systems is often wasteful, creating inefficiencies that need to be urgently addressed to reduce the over-consumption of our limited natural resources. Here, Jana Fried, Adina Paytan and Waste FEW ULL project participants look at lessons from the Waste FEW ULL project for reducing waste and increasing efficiency in the FEW nexus.

Abstract The Urban Living Lab (ULL) approach has the potential to create enabling environments for social learning and to be a successful arena for innovative local collaboration in knowledge co-creation and experimentation in the context of research and practice in sustainability transitions. Nevertheless, complex issues such as the urban Food-Water-Energy (FWE) Nexus present a challenge to the realization of such ULL, especially regarding their inclusiveness. We present ULL as a frame for a local knowledge co-creation and participation approach based on the project "Creating Interfaces - Building capacity for integrated governance at the Food-Water-Energy-nexus in cities on the water". This project aims at making FWE Nexus linkages better understandable to the stakeholders (citizens and associations, city government, science, businesses), and to facilitate cooperation and knowledge exchange among them. This paper focuses on and discusses inclusiveness as a key aspect and challenge of ULLs and on what literature and our experiences in this regard suggest for the advancement of the concept of ULL towards ULL 2.0. These findings often also relate to framing transdisciplinary research in a wider sense.more » « less

Interdisciplinary environmental and sustainability (IES) programs are different from other fields because they focus on a complex integration of humanities, social, and natural sciences concepts centered on the interactions of coupled human and natural systems. The interdisciplinary nature of IES programs does not lend itself to traditional discipline-specific concept inventory frameworks for critically evaluating preconceptions and learning. We discuss the results of the first phase of a research project to develop a next generation concept inventory for evaluating interdisciplinary concepts important for introductory IES courses. Using the Food-Energy-Water (FEW) Nexus (the intersections/interdependencies of food, energy, and water sectors) as our focus, we conducted a content analysis of eight representative college-level introductory environmental course syllabi and course materials (e.g., textbooks, journal articles, print media) to identify common interdisciplinary FEW Nexus concepts taught in introductory IES courses. Results demonstrate that all IES introductory course materials reference the FEW Nexus. Food, energy, and/or water resources as individual elements of the FEW Nexus are frequently described, but connections between these resource systems are included less often. Biology, energy systems, waste and pollution in the natural environment, agriculture, earth sciences and geology, climate change, behavioral social sciences, and economics concepts are most associated with FEW concepts, hinting at commonalities across IES topics that anchor systems thinking. Despite differences in IES programs, there appears to be some alignment between core concepts being taught at the FEW Nexus in introductory courses.more » « less

Solutions to waste management in informal settlements in South Africa South Africa has retained some of the unjust laws following the Apartheid system, but rapid urbanisation has resulted in burgeoning informal settlements, often situated on the periphery of major cities and towns, where clean water is often inaccessible and waste management is limited. Clean water is the main catalyst for the projects conducted by the Waste FEW ULL team, Kevin Winter, Adina Paytan, Sue Charlesworth, and Jana Fried. The motivation for developing the ULL arose out of concern about the contaminated water and its impact on human health and the environment. Rising demand for land and houses has made people struggle to overcome existing income and wealth disparities, with high levels of unemployment and poverty remaining, leaving many only able to live in so-called informal settlements. The concept of Urban Living Labs (ULLs) has advanced from centres that were largely seen as test beds of innovation to become sites of learning and places where stakeholders can co-create solutions to address critical issues and challenges.more » « less

Food, energy and water (FEW) systems are inextricably linked, and thus, solutions to FEW nexus challenges, including water and food insecurity, require an interconnected science and policy approach framed in systems thinking. To drive these solutions, we developed an interdisciplinary, experiential graduate education program focused on innovations at the FEW nexus. As part of our program, PhD students complete a two-course sequence: (1) an experiential introduction to innovations at the FEW nexus and (2) a data practicum. The two courses are linked through an interdisciplinary FEW systems research project that begins during the first course and is completed at the end of the second course. Project deliverables include research manuscripts, grant proposals, policy memos, and outreach materials. Topics addressed in these projects include building electrification to reduce reliance on fossil fuels for heating, agrivoltaic farming to combat FEW vulnerabilities in the southwestern United States, assessment of food choices to influence sustainable dining practices, and understanding the complexities of FEW nexus research and training at the university level. Evaluation data were generated from our first three student cohorts (
n = 33 students) using a mixed method, multi-informant evaluation approach, including the administration of an adapted version of a validated pre-post-survey to collect baseline and end-of-semester data. The survey assessed student confidence in the following example areas: communication, collaboration, and interdisciplinary research skills. Overall, students reported confidence growth in utilizing interdisciplinary research methods (e.g., synthesize the approaches and tools from multiple disciplines to evaluate and address a research problem), collaborating with range of professionals and communicating their research results to diverse audience. The growth in confidence in the surveyed areas aligned with the learning objectives for the two-course sequence, and the interdisciplinary project experience was continually improved based on student feedback. This two-course sequence represents one successful approach for educators to rethink the traditional siloed approach of training doctoral students working at the FEW nexus.
