If cities could become regenerative and adaptive urban ecosystems, in which resource loops were closed and waste was obsolete, their ecological footprint would diminish. In addition, urban resource security would increase, the health of urban populations would improve and urban greenhouse gas emissions would be reduced. These are the principle goals under-pinning the circular city. Circular cities emerge through the process of circular development. Circular development alters cities’ systems of provision to enable circular practices of inhabitants to develop. This manifests as circular food systems and construction, water and nutrient recycling; adaptive reuse of spaces and pop-up activities; bioremediation of contaminated sites and integration of blue-green infrastructure throughout cities. To transform our cities will require significant investment, political support and public engagement. If the benefits of adopting such an approach can be identified, this will begin to make the case for support. The research presented in this paper draws on an inductive and deductive content analysis of relevant literature and interviews with those implementing circular projects in European cities (London, Paris, Amsterdam and Stockholm). It provides a clear definition of the normative concept of circular development. It creates a framework of benefits which are likely to accrue from adopting this approach. It points to the synergistic benefits emerging from circular development. It also highlights problems around valuation of those benefits, the unintended consequences of circular development and the inequalities in accessing benefits across society.

Chapter 3 sets out the key theories with which the book engages: food insecurity and the human right to food. Following on from a conceptualisation and definition of food insecurity, the right to food is introduced. Emphasis is placed on normative element of ‘adequacy and sustainability of food availability and access’ and on the state’s obligation to ‘respect, protect and fulfil the right to food’. Theories of ‘othering’ and ‘agency’ are employed to assess the social acceptability of emergency food systems as a means of acquiring food, and the power of providers to make sufficient food available through these systems and of potential recipients to access it. Theories of ‘care’ and ‘social protection’ are employed to explore the ways in which charitable providers are in practice taking responsibility for the duty to respect, protect and fulfil the right to food and how shifts in welfare policy are affecting need for this provision.

AbstractDramatic changes taking place locally, regionally, globally, demand that we rethink strategies to improve public health, especially in disadvantaged communities where the cumulative impacts of toxicant exposure and other environmental and social stressors are most damaging. The emergent field of Sustainability Science, including a new bioregionalism for the 21st Century, is giving rise to promising place-based (territorially rooted) approaches. Embedded in this bioregional approach is an integrated planning framework (IPF) that enables people to map and develop plans and strategies that cut across various scales (e.g. from regional to citywide to neighborhood scale) and various topical areas (e.g. urban land use planning, water resource planning, food systems planning and “green infrastructure” planning) with the specific intent of reducing the impacts of toxicants to public health and the natural environment. This paper describes a case of bioregionally inspired integrated planning in San Diego, California (USA). The paper highlights food-water-energy linkages and the importance of “rooted” community-university partnerships and knowledge-action collaboratives in creating healthy and just bioregions.

The  concept  of  Green  Infrastructure  (GI)  is  still  relatively  new  in  the  Czech Republic. When looking at the definition of GI, one can recognise a  relationship  with  the  Czech  Territorial  System  of  Ecological  Stability  (TSES),  which  is  defined  as  “an  interconnected  system  of  natural  as  well as modified semi-natural ecosystems keeping the natural balance”. TSES is a designed system and is an integral part of territorial plans. This article focuses on TSES and its relationship to GI, how it is implemented in  a  Czech  case  study  representing  intensively  used  agricultural  region  in  South  Moravia,  what  the  main  obstacles  are  to  its  implementation  and how TSES can contribute to the connectivity of the landscape. Our results show that nearly two thirds of the planned TSES in the case study area  already  exist  to  some  degree.  There  is  a  difference  between  the  number  and  the  area  of  existing  TSES  elements:  the  area  of  existing  elements  shows  higher  relative  values  than  the  number.  This  is  mainly  due to bio-centres that exist in large forest complexes and their pre-set minimal parameters. Creation of TSES elements increases connectivity of GI, especially those characterised as core areas and bridges

This study followed a chronological review of literature over the past 20 years. This was able to show relationship between inclusivity and physical development. A variety of discussions were looked into including dimension of inclusivity, definition of inclusivity, scales for measurement of inclusivity, methodology for appraising inclusivity, protagonists of inclusivity, and antagonists of inclusivity. The intricacy of the correlations between inclusive physical development and life expectations of residents are improved upon so as to show the similarities of these parameters. The analysis of the relevant literature indicated the process of enhancing the urban space and ensuring that all interest and strata of groups in the human composition are adequately cared for by employing the best parameters from the conceptualization of the city development, all the indicators of inclusiveness are well thought out.

While higher education has been considered as both an ‘engine’ for innovation and a ‘catalyst’ for sustainability development, the integration of both the ‘innovation engine’ and ‘sustainability catalyst’ roles is best reflected in higher education’s engagement in innovation ecosystems—the theme of this special issue, including 16 articles dealing with the topic from various perspectives. In this editorial, we outline an overarching framework about the relations between higher education and innovation ecosystem. When elaborating the framework, we provide a new definition of innovation ecosystem and identify three roles of university in innovation ecosystems, based on synthesizing relevant literature. The framework could facilitate readers to comprehend each of the collected articles and find synergy among them.

Abstract A central dilemma in human rights law is how to reconcile the government’s duty to respect freedom with its obligation to protect individuals that might be harmed by the exercise of said freedom. Intolerance toward the dissemination of certain illiberal positions may have adverse social and political unintended results. One central concern is that such a policy would create a common culture that does not appreciate the critical importance of a vibrant public discourse. As such, it might enable governments, in terms of popular legitimacy, to curtail speech beyond the limits of justifiable infringements. Recent developments in Israel illustrate this concern. In recent years, normatively legitimate antiracism legislation was unjustifiably expanded by imposing sanctions on expressions that were deemed harmful to national sentiments or questioning the legitimacy of Israel’s Constitutional Identity as a Jewish state. Similarly, laws against the support of terrorism were followed by prohibitions on advocating boycotts against Israel. This Article proposes to halt the sociological slippery-slope trend of curtailing speech far and beyond the permissible scope of such a policy, by implementing rules-based legal doctrines that may foster a stronger public pressure on the government to protect free speech; restricting the scope of “harm-in-one-step” approach; and providing a clearer definition of the requirement of state neutrality in the context of regulating speech.

Abstract Research and practice during the last 20 years has shown that urban agriculture can contribute to minimising the effects of climate change by, at the same time, improving quality of life in urban areas. In order to do so most effectively, land use and spatial planning are crucial so as to obtain and maintain a supportive green infrastructure and to secure citizens' healthy living conditions. As people today trend more towards living in green and sustainable city centres that can offer fresh and locally produced food, cities become again places for growing food. The scope of urban agriculture thereby is to establish food production sites within the city's sphere; for example, through building-integrated agriculture including concepts such as aquaponics, indoor agriculture, vertical farming, rooftop production, edible walls, as well as through urban farms, edible landscapes, school gardens and community gardens. Embedded in changing urban food systems, the contribution of urban agriculture to creating sustainable and climate-friendly cities is pivotal as it has the capacity to integrate other resource streams such as water, waste and energy. This article describes some of the current aspects of the circular city debate where urban agriculture is pushing forward the development of material and resource cycling in cities.

Purpose: In this paper, we begin to set out language defining sustainable food systems (SFS) in Canada, through the voices of dietitians, and identify leverage points where dietitians can affect change. Methods: Dietitians of Canada members were invited to a Delphi Inquiry process; questions explored a vision of SFS in Canada, barriers to that vision, and actions. Results were independently analysed by 2 members of the research team who used the Framework for Strategic Sustainable Development to structure the data. Results: Fifty-eight members participated. The resultant vision describes a future food system in 15 thematic areas of the social and ecological systems. Barriers are described according to how they undermine sustainability. High-leverage actions areas included: (i) facilitating knowledge development within the profession and public, (ii) influencing organizational policy to support SFS, and (iii) and influencing public policy. Approaches to such action included: (i) facilitating cross-sectoral collaboration and (ii) applying reflexive approaches. Conclusions: This research suggests a multidimensional understanding of food systems sustainability among dietitians. The vision provides some language to describe what dietitians mean by SFS and can be used as a compass point to orient action. Action areas and approaches have the potential to drive systemic change while avoiding unintended consequences.

AbstractConventional failure analysis ignores a growing challenge in the responsible implementation of novel technologies into engineered systems - unintended consequences, which impact the engineered system itself and other systems including social and environmental systems. In this paper, a theory for unintended consequences is developed. The paper proposes a new definition of unintended consequences as behaviors that are not intentionally designed-into an engineered system yet occur even when a system is operating nominally, that is, not in a failure state as conventionally understood. It is argued that the primary cause for this difference is the bounded rationality of human designers. The formation of unintended consequences is modeled with system dynamics, using a specific real-world example, and bifurcation analysis. The paper develops propositions to guide research in the development of new design methods that could mitigate or control the occurrence and impact of unintended consequences. The end goal of the research is to create a new class of failure analysis tools to manage unintended consequences responsibly to facilitate engineering design for a more sustainable future.

Five years ago, with the editorial board of Frontiers in Nutrition, we took a leap of faith to outline the Goals for Nutrition Science – the way we see it (1). Now, in 2020, we can put ourselves to the test and take a look back. Without a doubt we got it right with several of the key directions. To name a few, Sustainable Development Goals (SDGs) for Food and Nutrition are part of the global public agenda, and the SDGs contribute to the structuring of international science and research. Nutritional Science has become a critical element in strengthening work on the SDGs, and the development of appropriate methodologies is built on the groundwork of acquiring and analyzing big datasets. Investigation of the Human Microbiome is providing novel insight on the interrelationship between nutrition, the immune system and disease. Finally, with an advanced definition of the gut-brain-axis we are getting a glimpse into the potential for Nutrition and Brain Health. Various milestones have been achieved, and any look into the future will have to consider the lessons learned from Covid-19 and the sobering awareness about the frailty of our food systems in ensuring global food security. With a view into the coming 5 years from 2020 to 2025, the editorial board has taken a slightly different approach as compared to the previous Goals article. A mind map has been created to outline the key topics in nutrition science. Not surprisingly, when looking ahead, the majority of scientific investigation required will be in the areas of health and sustainability.Johannes le Coutre, Field Chief Editor, Frontiers in Nutrition.
