This title was first published in 2002. The concept of sustainable development has increasingly gained currency as a policy determination tool, yet its interpretation and application is widely contested, especially with respect to the role of economics in the facilitation of environmentally and socially sustainable outcomes. Sarah Lumley assesses some of the fundamental assumptions of mainstream economic theory as part of an analysis of farmers' motives in adopting soil conservation on degraded lands in the Philippines. The text has a strong focus on the theoretical and practical interactions between environmental, economic and social aspects of sustainable development; it is both multidisciplinary and transdisciplinary, and draws on conceptually important points of each discipline that it encompasses.
