from Part Two - Exploring images of the future
Published online by Cambridge University Press: 06 July 2010
This chapter synthesises the insights gained from the model experiments made in the previous five chapters. The hierarchist utopia examined in Chapter 11 is only one possible future. We now explore the consequences of two other utopian futures: the egalitarian and the individualist. A selection of conditional forecasts from integrated simulation experiments with population, food, water and energy supplies, land use, global temperature and sea-level rise are presented. One way of looking at the model outcomes is by focusing on the various transitions which characterise the development of the human-environment system. Extending the time horizon of the model simulations into the 22nd century yields additional insights into the relation between the human and the environmental system.
Introduction
The main goal of the TARGETS 1.0 model is to place possible developments within the subsystems of the world in an integrated perspective. In Chapters 12 to 16, simulation results of experiments with the TARGETS 1.0 submodels are discussed in isolation, while in Chapter 11 the results of an integrated simulation experiment for the hierarchist utopia are presented. In this chapter, we pursue this analysis further and include the other two perspectives. In this way we elaborate on the various controversies which have been raised in the preceding chapters: can a large population be maintained at an adequate health level and will there be enough energy, water and food without overburdening the natural environment? We start with the integrated utopias which are based on assumptions about world view and management style taken from a single perspective for all submodels (see Table 11.1).
