Challenges in Sustainability

Abstract: The existing economics literature neglects the important role of capacity in the production of renewable energy. To fill this gap, we construct a model in which renewable energy production is tied to renewable energy capacity, which then becomes a form of capital. This capacity capital can be increased through investment, which we interpret as arising from the allocation of energy, and which therefore comes at the cost of reduced general production. Requiring societal well-being to never decline—the notion of sustainability favored by economists—we describe how society could optimally elect to split energy in this fashion, the use of non-renewable energy resources, the use of renewable energy resources, and the implied time path of societal well-being. Our model delivers an empirically satisfactory explanation for simultaneous use of non-renewable and renewable energy. We also discuss the optimality of ceasing use of non-renewable energy before the non-renewable resource stock is fully exhausted.

Abstract: Public participation is a common element in state-of-the-art urban development projects. Tailoring the public participation process to the local context is a popular strategy for ensuring sufficient turnout and meaningful engagement, but this strategy faces several challenges. Through a review of case studies of public participation in urban development projects, we identify ten typical misalignments between the public participation process and the local context, including the lack of policy maker support, adverse personal circumstances of participants, low collaborative capacity, and mistrust, among others. When a public participation process is not aligned to the local context, the process may generate outcomes that compromise public interests, inequitably distribute benefits among stakeholders, or favor powerful private interests. This study offers caution and guidance to planning practitioners and researchers on how to contextualize public participation in urban development projects through the categorization of common misalignments that ought to be avoided.
