Viability and Resilience of Complex Systems
by Nigel Gilbert Guillaume DeffuantOne common characteristics of a complex system is its ability to withstand major disturbances and the capacity to rebuild itself. Understanding how such systems demonstrate resilience by absorbing or recovering from major external perturbations requires both quantitative foundations and a multidisciplinary view on the topic. This book demonstrates how new methods can be used to identify the actions favouring the recovery from perturbations. Examples discussed include bacterial biofilms resisting detachment, grassland savannahs recovering from fire, the dynamics of language competition and Internet social networking sites overcoming vandalism. The reader is taken through an introduction to the idea of resilience and viability and shown the mathematical basis of the techniques used to analyse systems. The idea of individual or agent-based modelling of complex systems is introduced and related to analytically tractable approximations of such models. A set of case studies illustrates the use of the techniques in real applications, and the final section describes how one can use new and elaborate software tools for carrying out the necessary calculations. The book is intended for a general scientific audience of readers from the natural and social sciences, yet requires some mathematics to gain a full understanding of the more theoretical chapters. It is an essential point of reference for those interested in the practical application of the concepts of resilience and viability
Viability and Sustainability of Small-Scale Fisheries in Latin America and The Caribbean (MARE Publication Series #19)
by Ratana Chuenpagdee María José Barragán-Paladines Silvia SalasOne of the main goals in fisheries governance is to promote viability and sustainability in small-scale fishing communities. This is not an easy task given external and internal pressure, including environmental change and competition with other economic sectors searching for development in the coastal region. A comprehensive understanding of small-scale fisheries in their own context, and from a regional perspective, is an important step in supporting the implementation of the Voluntary Guidelines on Securing Sustainable Small-Scale Fisheries (SSF Guidelines). This book contributes to the global effort by offering knowledge, insights and lessons about small-scale fisheries in Latin America and the Caribbean. The 20 case studies included in the book make explicit the various dimensions that are intrinsic to small-scale fisheries in the region, and identify conditions and situations that affect the wellbeing of fishing communities. The book offers insights regarding the challenges faced by small-scale fisheries in the region, and, aligning with the objectives of the SSF Guidelines, provides lessons and experiences about how to make small-scale fishing communities viable while maintaining sustainable fisheries. This important book illustrates the complexity, diversity, and dynamics of small-scale fisheries in the Latin American and Caribbean region and presents experiences, tools, and approaches to lead towards sustainable and viable fisheries. The reader will gain a new understanding on the range of actions, approaches, and information needed for their successful management. John F. Caddy, International Fisheries ExpertThis book, prepared by the Too Big To Ignore partnership, constitutes a very valuable resource for policy makers, fisheries scientists, non-governmental organizations, civil society organizations, and fishing communities interested in putting in place sound management strategies, research, and actions to contribute to the sustainability of small-scale fisheries and food security in Latin America and the Caribbean region.
