World fisheries are currently largely depleted across the globe. Despite the intent of governments and international organisations to effectively manage fisheries—and thereby reduce adverse impacts on marine ecosystems, it appears that oceans are evermore under threat. One option to reverse this accelerating depletion of marine resources is to seek to authorise only those fishing practices and policies that have a positive societal benefit. However, in order to do this, one needs to measure the societal costs and revenues of each fishing practice and each fishery policy, compare them, and then use the findings to inform public policy. The novelty of this approach, presently being developed in an international research project (ECOST, 2006/2010), is the way in which ecological, economic and social costs are combined to give a true value of the real cost of fishing activity—a cost that is not captured by current market mechanisms. The modelling work in process that supports this approach seeks to integrate different values (market values and non market values) in a holistic manner. Nevertheless, non market values are very difficult to incorporate into the model and there is a risk that attempts to do so (as in the case of option values) may simply undermine the strength and meaning of factors possessing non-market values. Therefore, a parallel aspect of the research demands a deep study of the characteristics of the human valuing processes in order to grasp the epistemès embedding them, the values that society gives to the sea and the entities therein. In the last analysis, these values, in a sense, function as underpinnings to our modelling activity—and bring a more profound meaning to the measurement of the societal costs of fishing practices and fishery policies. This chapter lays down the foundations of this modelling approach on the interactions between ecology, economy and society and examines briefly its significance for policy implementation.
Current Trends in Human Ecology Anthropology, sociology, and ecology come together in this book, where the unifying goal of theorizing and practising interdisciplinarity in human ecology is shown by, closely tracking examples of current trends and developments. This book is a harvest from the XV International Meeting of the Society for Human Ecology, held in Rio de Janeiro, Brazil, October 4-7, 2007. This volume ends by indicating several lines of thought and of analyses on current subjects, as follows: sustainability in different cultural contexts and perspectives, methods towards approaching sustainable systems, and current global concerns. Those include agriculture in tropical areas (slash-and-burn practices), climate change, and nature and human behavioural patterns, among others.
