Biases and environmental risks in urban Africa: household solid waste decision-making

Abstract

We argue in this paper that the urban environmental planning and management literature has paid insufficient attention to the nexus of risk and human psychology in urban dynamics, particularly for the rapidly urbanizing areas of the Global South. We then draw on two household surveys in Dar es Salaam, Tanzania to present two empirical examples that incorporate these dimensions, using solid waste management as a contemporary urban environmental challenge. These examples illustrate the sensitivity of behavioral preferences to the framing of risks, and the influence of risk preferences on solid waste behavior. Incorporating such concepts into environmental planning and management research offers the potential to increase understanding of urban dynamics and to improve the environmental quality of life in urban Africa and elsewhere in both developing and developed country settings.
