In previous chapters, attention focused upon the nature of complex social-ecological systems, visions for the future, characteristics of an ecosystem or holistic approach, issues related to governance, the nature of adaptive environmental management, attributes of partnerships and stakeholders, and alternative ways to resolving disputes. For all of these matters, alternative approaches exist and choices must be made. This chapter focuses on three methods for identifying and assessing alternatives: benefit-cost analysis; environmental impact assessment, including strategic environmental assessment; and life-cycle assessment, including ISO 14001 and the European Union’s eco-management and audit scheme (EMAS). Case studies are provided from China, the Republic of Kiribati in the Pacific Ocean, Thailand, Indonesia and Malaysia, and Italy. Bram Noble, in his guest statement, examines alternative ways to address uncertainty in environmental impact assessments in the context of Canada.
