This paper details a system dynamics model developed to simulate proposed changes to water governance through the integration of supply, demand and asset management processes. To effectively accomplish this, interconnected feedback loops in tariff structures, demand levels and financing capacity are included in the model design, representing the fi...
Article
Full-text available
Water supply and demand planning is often conducted independently of social and economic strategies. There are presently no comprehensive life-cycle approaches to modelling urban water balances that incorporate economic feedbacks, such as tariff adjustment, which can in turn create a financing capacity for investment responses to low reservoir leve...

The exponential uptake of solar energy systems raises a concern on the looming waste problems once the panels and batteries reach the end-of-life. It was projected that residential solar panel waste will increase exponentially to 1,532 kT, whereas end-of-life battery energy storage will rise to 99.1 kT in 2050. An appropriate scheme to manage these...
