Cover artArmando Paez says that scarcity is not inherent to nature, but it has emerged from the tendency of looking at everything in terms of domination and submission, from the misunderstanding of the relations between humanity and the rest of nature. This cover expresses how close humans are to nature, even when they insist on distancing themselves from it. The reticulate patterns in this leaf resemble the streets and waterways of a city. In nature, this structure works in a way that ensures that every single cell has access to water and nutrients. Cities are places for everyone and they should work in the same way, providing everything their inhabitants need: clean air, water and soil, food, spaces for social interaction, and security. The foundations for more sustainable cities are laid; perhaps we need to improve our cities' ability to adapt to the nature that supports them.
AbstractThe aim of this thesis is to analyze the role that environmental technology plays in the solution of environmental problems in cities, and discuss models and conditions that can facilitate the processes of selection, implementation and use of environmental technologies in and by cities.The technological component is perhaps one of the most important characteristics of modern cities. The dependence of humans on technology is in most cases a given, something that is not ignored in the sustainability debate. The development and implementation of new, "better" technologies is however hindered by the inertia that modern societies have and the influence of the dominant systems (e.g. economic systems based on growth, extraction of natural resources and environmental disturbance). So-called environmental technologies are not always able to efficiently compete against other technologies that are embedded in societies by lock-in mechanisms, e.g. learning by doing and using, scale economies, subsidies, and network externalities.Even with the "right" technologies, an exclusively techno-centered approach to sustainability can result in other problems, and it might reduce the sustainability debate and the cities' role in it to discussions of an administrative nature. The actual role of local actors and their agency must be also considered in the models and frameworks directed at understanding sustainability transition processes. It is thus important to analyze the dynamics of technology selection, implementation, use and diffusion in cities from a stakeholders' perspective as well.Not only is the availability of technology of interest for understanding the impact it has on the environment, but also the intensity of its use. This has resulted in increased attention from politicians and scholars on the so-called global cities (e.g. London, New York, Tokyo), which are characterized by their intense use of e.g. transport, security and surveillance, and information and communication. Paradigmatic models of sustainability can however be contested when the role of local actors, power and agency are considered in detail and not isolated from ...
