Achieving societal impact, as opposed to academic impact, is a growing area of focus for the research community globally. Central to this changing mission is the focus on multiple interconnected complex systems and the need for research that is not just interdisciplinary, but also transdisciplinary and grounded in stakeholder co-production. This document compares multiple approaches to impact planning and evaluation across four newly formed urban living labs in Sao Paolo (Brazil), Western Cape (South Africa), Bristol (UK) and Rotterdam (Netherlands), each of which sought to address societal issues linked to the food-energy-water nexus. A comparison matrix and a disaggregated impact table are derived from a comprehensive review of key definitions. These new tools were completed by each ULL alongside a post hoc pathway to impact statements. Comparisons are presented and discussed, the strengths and weaknesses of this approach are considered and opportunities for improvement in societal impact planning and evaluation are provided. Our main findings include the importance of establishing clear shared definitions while accepting plural understandings, the need to acknowledge resource as a critical factor in impact delivery and the headline need for far greater focus in this area from both funders and research groups. 

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. 

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. 

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. 

This study analyzes the impact of corruption on the elasticity of R&D investments in sales per worker by firms. In this sense, it built a model of Schumpeterian growth using optimal control theory relating the effects of corruption on demand for R&D. The model results show that corruption negatively affects the R&D demand and long-term rate of technical progress. However, this cost attributes different 'weights' as firms approach the technological frontier. To empirically test this relationship, it was built partial order-฀ frontiers on a sample of 2,000 firms from 40 sectors and 46 countries. Interacting efficiency scores with the corruption index, the less-efficient firms are disadvantaged with corruption in relation to the frontier firms. This pattern is observed in the coefficient of elasticity of R&D investments indicating that corruption leads to different costs, 'favoring' the most efficient firms in relation to the most backward firms.
