“…Yet assigning value to these "intangibles" and, more specifically, linking those valuations to critical decision-making, is not straightforward [11,12,35]. There are many parts of the decision-making "system and systems" that need recalibrating in order to better understand and promote urban health and the sustained functioning of socioecological systems [70][71][72]. As underlined above, the uncertainties inherent in this exercise are significant (e.g., much will depend on changing patterns of behaviour), and are open to critique.…”

Bristol, one of the United Kingdom’s (UK) nine Core Cities, is seeking to achieve Zero Waste City status by 2049. This study combines macro-economic valuation with transition pathway mapping and adapted participatory scenario planning to stress test the city’s ambitious food waste targets. The primary aim is to enable better understanding of who might be affected by achieving these targets, both locally and nationally, the potential scale of impacts, and therefore the potential barriers and policy opportunities. The valuation focuses on household and commercial food waste, combining available site and city data with national level proxies. Impact areas include changes in sectoral income, employee income, capital owner income, tax revenue, and carbon emissions. Four scenarios, based on two extreme cases, are modelled to consider food waste reduction and potential shifts in consumption patterns. Results indicate that current market and governance failures incentivise waste, and suggest potential routes to transition, including trade-offs and resource reallocation, alongside the need to acknowledge and respond to these profound structural barriers. With further development and testing, the approach may contribute to a better understanding of how to achieve city socioenvironmental targets.

Complexity and stability of ecological networks: a review of the theory

et al. 2018

Our planet is changing at paces never observed before. Species extinction is happening at faster rates than ever, greatly exceeding the five mass extinctions in the fossil record. Nevertheless, our lives are strongly based on services provided by ecosystems, thus the responses to global change of our natural heritage are of immediate concern. Understanding the relationship between complexity and stability of ecosystems is of key importance for the maintenance of the balance of human growth and the conservation of all the natural services that ecosystems provide. Mathematical network models can be used to simplify the vast complexity of the real world, to formally describe and investigate ecological phenomena, and to understand ecosystems propensity of returning to its functioning regime after a stress or a perturbation. The use of ecological-network models to study the relationship between complexity and stability of natural ecosystems is the focus of this review. The concept of ecological networks and their characteristics are first introduced, followed by central and occasionally contrasting definitions of complexity and stability. The literature on the relationship between complexity and stability in different types of models and in real ecosystems is then reviewed, highlighting the theoretical debate and the lack of consensual agreement. The summary of the importance of this line of research for the successful management and conservation of biodiversity and ecosystem services concludes the review.
