Ecological economics is a multidisciplinary endeavour to connect the social sciences and nature in general. It also connects aspects of ecology and economics to a particular understanding. The created concept centred on the mission to acquire a more advanced albeit better scientific understanding of the complex interconnections between humans, animals and the rest of nature. This is driven towards utilising the obtained knowledge to establish policies that will lead to a more environmentally sustainable world, with a fair resource distribution (both across human groups and generations, as well as between humans, the environment and other species), and also efficiently allocates limited resources such as ‘natural’ and ‘social’ capital. This practice necessitates the development of new methodologies that are comprehensive, adaptive, integrative, multi-scale, pluralistic and evolutionary, while also acknowledging the enormous uncertainties involved.

Environmental justice activism is increasingly globalized, multi-faceted and multi-scaled (Bickerstaff & Agyeman, 2009; Walker, 2009a, 2009b). The existence or perception of injustice triggers the development of social activism in increasingly diverse contexts. The present contribution seeks to assess the explanatory value of resources in understanding activism (Freeman, 1979). In place of justice, the under-studied social movement theory of resource mobilization is explored as a complementary and partly oppositional account of justice activism. The highly controversial anti-GMO movement in France is selected as an invigorating context for evaluating activism. The perceived injustice of lifting restrictions on the importation of GM maize into France inspired the mobilization of a nationwide movement. In sharp contrast to existing literature, ideology is considered as a resource that effectively promotes or hinders social activism. Significant conclusions are developed for environmental justice activism research around emphasizing instability, heterogeneity, cultural sensitivity and above all, the limitations of agency-centric arguments.

The aim of this section is to develop a model of the linkage between the macro-dynamics of price and the micro-dynamics of individual buyers and sellers, drawing on classical micro-economic theory (Jehle & Reny, 2001). Jehle and Reny's book is in three parts. The first part discusses economic agents, namely consumers and firms. The second part discusses markets, in other words what happens when the economic agents interact; and welfare, namely the social value of the outcome. The third part is on strategic behaviour, covering game theory, information economics and auctions and mechanism design. Here, the emphasis will be on the core concepts rather than on the mathematical details. In emphasising the core concepts, attention will be drawn to the fact that these core concepts have a much wider range than simply micro-economics.

The earth’s carrying capacity cannot withstand the pace of consumption resulting from current economic models, mainly the linear economy (LE) built on a throwaway culture. In the last few decades, the concept of a circular economy (CE), aiming to design waste out of the economy and mimic ecosystems, emerged as a strong alternative to LE. Being at the heart of the economic landscape, supply chains (SCs) need to respond to the necessary shift to CE. In so doing, the planning and execution of circular supply chains (CSCs) require a broader comprehension of CE and more sophisticated and large-scale analytical decision models. This chapter surveys extant literature on available best practices and quantitative models for sustainable supply chains (SSCs) and offers a new definition of CSC. Mapping on the knowledge extracted from this classification, potential gaps and strengths in the literature are identified. Key research papers on the “closed-loop” and “open-loop” ends of CSCs are highlighted. Challenges in developing CSC performance indicators and prescriptive models are emphasized.

This chapter discussed the implementation of the digital twin (DT) idea into construction. Through the adoption of DTs into construction practices, construction professionals have been able to project an identical virtual concept of sections of the project execution right from the onset. In the introduction and discussing of its origin, the DT was further assessed about its applications in construction beneficial in enhancing project delivery. Other sections like barriers, drivers and benefits of the DT in construction summarised what this chapter represents in terms of discussing the new involvement of digital tools in construction execution, management and sustainability.
