- City–Region Food Systems (CRFS) is a cutting-edge concept and an emerging field of research. As a new analytical lens, it offers an integrated and multi-dimensional perspective on food’s origins, how it is grown and the path it follows to our plates and beyond. Building on this concept, this presentation reflects a prospective research project which seeks to explore opportunities for innovative and sustainable food systems in the Gothenburg region of Sweden by focusing on how rural and urban regions, food production and market can be integrated to promote regional food security. The project intends to: 1) develop scenarios with stakeholders for local food production in the region; 2) analyze the consequences of the scenarios on landscape change and biodiversity; 3) explore socio-economic consequences for producers and local communities; and 4) evaluate the sustainability and feasibility of scenarios with stakeholders. Five municipalities in Western Sweden (Gothenburg, Kungälv, Lerum, Alingsås and Essunga) will serve as study areas for the project, selected to reflect different kinds of potential for local food production in terms of dissimilar environmental conditions, prerequisites for farming and economic histories. The project responds to expressed interests and knowledge needs in the region and will be developed and implemented in direct cooperation with local and regional actors such as Västarvet, the Västra Götaland Region, the municipalities and various producer organizations. In sum, there are premises suggesting that recent urban food strategies and plans with sustainability ambitions are embracing several Sustainable Development Goals in the environmental, social, economic, and equity dimensions. This, in turn, is a characteristic of the Transition Movements pathway, in which the utility of food strategies in the work with sustainability transitions seems inevitable. The results are therefore likely to be transferable to other regions.

- Climate change increases the risk of damage caused by storms, insects and fungi in agriculture and forestry. Multifunctional sustainable land use, including a more diversified agriculture and forestry sector in terms of biodiversity, is one way to create resilience and meet these climate risks. For example, a forest with trees of different ages and of several species is more resistant to these risks. Multifunctional refers to how the same land can provide food and wood products, but also job creation, recreation and be a provider of ecosystem services such as pollination, erosion protection and biodiversity. Research shows that there is a large acceptance for a more varied forest sector and diversified agriculture. In recent years, urban farming has received widespread understanding on its many advantages, including a sense of belonging and meaning, other than food production. In this article the authors try to assess a scenario when these initiatives become commercial and when the urban farming trend meets traditional forms of agriculture and forestry. Furthermore, the large potential of developing public-private partnerships for multifunctional sustainable land use in peri-urban areas in the Swedish City of Gothenburg and its surrounding area is analysed, based on experiences from ongoing initiatives. Developed within the framework of Climate KIC Accelerator Project, a business model is presented allowing for a long-term sustainability of initiatives.

- The effects of reduced intercellular coupling in the sinus node were investigated by means of simulations. Coupling was reduced both uniformly, and by introducing localized interaction blocks. In either case, model sinus node element networks typically splitted into frequency domains. These were defined as groups of neighbour elements which all attained the same mean firing frequency. In systems, simulating the vicinity of an impulse outlet to the atrium, the sinus node elements often splitted into two domains, one slowly firing just inside the outlet, and one normally firing large domain in the sinus node interior. This two-domain situation was analysed using a two-element system. Wenckebach conduction and advanced (m:1) exit blocks were seen, together with more odd block patterns and slow chaotic rhythms. The two-domain situation appeared also when two discrete outlets were considered. The slow domains around each outlet synchronized via the atrium. However, if there were some degree of exit block through one of the outlets only, brady-tachy like rhythms could be simulated due to a re-entrant circuit including both sinus node and atrial tissue. In conclusion, poor coupling in the sinus node seems to be sufficient to produce most arrhythmias in the sick sinus syndrome.

- In an accompanying study, it was seen that most cardiac arrhythmias that were simulated during poor intercellular coupling in the sinus node, were the same as those obtained in a two-element system in which one element suffered from a strong leakage current. This element corresponds to the sinus node periphery and is thus the one which feeds the atrium. In this paper, the interior element was replaced by a periodic stimulator. The dynamics of the peripheral element is then determined by its phase response curve. Phase response curves for sinus node elements subject to leakage were simulated for many different amplitudes of depolarizing stimuli. Simulations with circle maps based on these curves produced the same sequence of progressing levels of exit block as stimulus strength decreased, as did the two-element system when coupling strength was reduced. The bifurcations of the circle maps leading to the observed rhythms were identified. We found that the essential qualities of the phase response curves were determined by generally accepted properties of membrane currents. This suggests that the observed rhythms and bifurcations are generic.
