Coastal Research Library 27 Lynn Donelson Wright C. Reid Nichols Editors Tomorrow’s Coasts: Complex and Impermanent Coastal Research Library Volume 27 Series editor Charles W. Finkl, Coastal Education and Research Foundation Boca Raton, FL, USA The aim of this book series is to disseminate information to the coastal research community. The Series covers all aspects of coastal research including but not limited to relevant aspects of geological sciences, biology (incl. ecology and coastal marine ecosystems), geomorphology (physical geography), climate, littoral oceanography, coastal hydraulics, environmental (resource) management, engi- neering, and remote sensing. Policy, coastal law, and relevant issues such as conflict resolution and risk management would also be covered by the Series. The scope of the Series is broad and with a unique cross-disciplinary nature. The Series would tend to focus on topics that are of current interest and which carry some import as opposed to traditional titles that are esoteric and non-controversial. Monographs as well as contributed volumes are welcomed. Charles W.

Climate change, sea level rise, ecosystem evolution, altered river discharge, and changes in the size, intensity, and duration of storms will accelerate the degradation of coastal realms over the decades ahead. The coastal systems and coastal communities of the future will be different from those of today. Foreword In no environment is the connection between people and nature stronger than in coastal systems. Climate change, sea level rise, ecosystem evolution, hydrologic modifications of river discharge to the coasts, and changes in the intensity and duration of storms and attendant coastal erosion are likely to accelerate the alter- ation of coastal realms over the decades ahead. In concert with these changes, the socioeconomic environment that underpins human coastal communities is also impermanent and dynamic. The interdependence of environmental and socioeco- nomic processes in the Anthropocene is already giving rise to suites of highly complex and nonlinear feedbacks, many of which are counterintuitive. Improved abilities to predict, communicate, mitigate, and respond to the outcomes of future coastal processes, gradual as well as abrupt, on both long-term and event timescales are essential to the welfare of coastal communities and to the sustainability of coastal ecosystems and built infrastructures. Those interested in understanding the complex nature of coastal processes must take an interdisciplinary approach to Earth system problems, and international collaborations to strengthen the rela- tionships between the physical and social sciences must be nurtured. The changes that are underway can be slowed, with a global commitment to do so, but most cannot be stopped. The coastal systems of the future will be different from those of today. Preparation of this general literature synthesis was undertaken as an initiative of the Southeastern Universities Research Association’s Coastal and Environmental Research Committee to lay a foundation for future collaborations aimed at improving predictions and strategies for responding to the complex changes that are occurring, and are expected to occur in the future, within the world’s diverse coastal systems. Strategies for ensuring the joint resilience of humans and nature will rely heavily on understanding how the many complex facets of the system interconnect and how they might evolve in the foreseeable future. This understanding must extend well beyond the scientific community to include decision-makers, politicians, and the general public. This synthesis is intended to contribute to that broad understanding and stimulate pursuit of forward-looking solutions. This is not a technical or specialized treatise. The intent is to provide a conceptual roadmap to show how some of the numerous pieces of vii viii Foreword complex coastal systems intersect and might interact under changing future envi- ronmental regimes. The book is addressed to a nontechnical but environmentally literate audience that includes the lay public, policy-makers, planners, engineers, environmental scientists, and academics interested in the causes and consequences of global environmental change and its effects on coastal systems. The book also outlines some strategies for anticipating and responding to the challenges that lie ahead. It is hoped that as future changes unfold, our understandings and abilities to predict will also evolve. Starkville, MS, USA David R.
