<p>Global change is a growing problem, governed by demographic, economic and climatological drivers. Such developments are leading to an increasing demand for natural resources. Traditionally, management of products and services from water, energy, and food sectors has been addressed with a sectoral policy approach (siloes) or through thematic modeling within individual sectors. However, this led to neglecting potential impacts of policy or resource changes in one sector on other sectors. A novel way to address this complexity is the nexus approach, which attempts to identify synergies and trade-offs between sectors. The water-energy-food (WEF) nexus approach offers opportunities to consider holistic policy integration and the nexus-wide impacts of adopted policies on physical interactions. In addition to the traditional WEF sectors, we believe that the climate and land sector are also of particular importance, because of their large potential influence on water, energy and food.</p><p>Consequently, in the present study, we adopted a multi-centric nexus approach to systematically investigate synergies, conflicts and trade-offs between the five nexus sectors of water, land, energy, food and climate in Sweden, that emerge both in interactions between physical resources and between different policy goals. This was done by combining a policy coherence analysis and system dynamics modelling. The policy analysis enabled us to identify key nexus-relevant policies, assess the coherence between them, and reveal the most important synergies and conflicts, while the system dynamics modelling allowed for the exploration of the physical interactions in this complex system. We here present the results of this extensive analysis, which was based on expert judgement, literature reviews, quantitative modelling and multi-stakeholder engagement at all stages of the project. The value of multi-stakeholder involvement is highlighted, and critical lessons learned for exploring nexus interactions are presented.</p>

Modelling Task

AbstractTo pursue business innovation with PSS, many different PSS concepts are designed and evaluated. Various business models of a PSS design concept are devised and evaluated as well. Evaluation of the economic sustainability of PSS business models is critical. This paper presents a systematic method to evaluate the economic sustainability of PSS business models using a system dynamics modelling template. System dynamics modelling task is challenging for practitioners due to the variety of variables comprising business model strategies and their complex interrelationships. To enable the modelling task, a system dynamics modelling template composed of six modules of customer acquisition, channel acquisition, profit creation, resource acquisition, PSS provision, and partnership pattern has been devised. The PSS business model evaluation method has been illustrated using a smart study experience management service system design case to demonstrate the proposed system dynamics modelling template can reflect the case-specific business model which consists of the particular business model strategies.
