Societal scenarios in deephousehold

Abstract

In this chapter, the societal scenarios in the DeepHousehold model and their results are presented. The Baseline societal scenario describes the continuation of existing conditions with respect to the distribution of milieus and their characteristics. The values thus directly stem from the current milieu properties and from empirical studies within the project. In the Performance scenario, the deregulation of society has diverse direct and indirect effects on the modelled households. As water is viewed as a commodity which has to be purchased, price is becoming more important. Also, insurance, e.g. against flood risks, plays a more important role. In the “Public Interest”� scenario however, the state is seen to have greater obligations compared to the other scenarios. This also means a focus on sustainability in terms of both the water supply and a sustainable consumption by households. The model results that are presented refer to the role of the so-called drinking water quantity flags as a mediator between natural science variables and actor variables, their impact on the activation of actors and on their behaviour (e.g. the adoption of water-saving technologies).
