Given the realities of climate change and sea level rise, coastal
cities around the world are struggling with questions of
resilience. Resilience, at its core, is about desirable states of
the urban social-ecological system and understanding how to sustain
those states in an uncertain and tumultuous future. How do physical
conditions ecological processes, social objectives, human politics,
and history shape the prospects for resilience? Most books set out
"the answer." This book sets out a process of grappling with
holistic resilience from multiple perspectives, drawing on the
insights and experiences of more than fifty Scholars and
practitioners working together to make Jamaica Bay in New York-City
an example for the world. Prospects for Resilience establishes a
framework for understanding resilience practice in urban
watersheds. Using Jamaica Bay, the largest contiguous natural area
in New York, home to millions of New Yorkers, and a hub of global
air travel with John F.Kennedy International Airport, the authors
demonstrate how various components of social ecological systems
interact, ranging from climatic factors to plant populations to
human demographics. They also highlight essential tools for
creating resilient Watersheds, including monitoring and identifying
system indicators; computer modelling; green infrastructure; and
decision science methods. Finally, they look at the role and
importance of a "boundary organisation" like the new Science and
Resilience Institute at Jamaica Bay in coordinating and
facilitating resilience work, and consider significant research
questions and prospects for the future-of urban watersheds.
Prospects for Resilience sets forth an essential foundation of
information and advice for researchers, urban planners, students
and others who need to create more resilient cities that work with,
not against, nature.
The Hudson River Estuary is a comprehensive look at the physical,
chemical, biological and environmental management issues that are
important to our understanding of the Hudson River. Chapters cover
the entire range of fields necessary to understanding the workings
of the Hudson River estuary; the physics, bedrock geological
setting and sedimentological processes of the estuary;
ecosystem-level processes and biological interactions; and
environmental issues such as fisheries, toxic substances, and the
effect of nutrient input from densely populated areas. This 2006
book places special emphasis on important issues specific to the
Hudson, such as the effect of power plants and high concentrations
of PCBs. The chapters are written by specialists at a level that is
accessible to students, teachers and the interested layperson. The
Hudson River Estuary is a fascinating scientific biography of a
major estuary, with relevance to the study of any similar natural
system in the world.
