Abstract

Wetlands perform functions that deliver benefits to society, often referred to as ecosystem services. These ecosystem services include water supply, flood regulation, water purification, climate regulation, biodiversity, agriculture (e.g. grazing land), and amenity. A functional approach to wetland assessment enables a holistic view to be taken of the wide range of services wetlands can provide. The functional assessment procedures (FAPs) in this volume translate best available scientific knowledge into reasonable predictions of how component parts of wetlands function in different landscape c

Abstract

The often impassioned nature of environmental conflicts can be attributed to the fact that they are bound up with our sense of personal and social identity. Environmental identity--how we orient ourselves to the natural world--leads us to personalize abstract global issues and take action (or not) according to our sense of who we are. We may know about the greenhouse effect--but can we give up our SUV for a more fuel-efficient car? Understanding this psychological connection can lead to more effective pro-environmental policymaking.Identity and the Natural Environment examines the ways in which our sense of who we are affects our relationship with nature, and vice versa. This book brings together cutting-edge work on the topic of identity and the environment, sampling the variety and energy of this emerging field but also placing it within a descriptive framework. These theory-based, empirical studies locate environmental identity on a continuum of social influence, and the book is divided into three sections reflecting minimal, moderate, or strong social influence. Throughout, the contributors focus on the interplay between social and environmental forces; as one local activist says, "We don't know if we're organizing communities to plant trees, or planting trees to organize communities."

Abstract

All phases of road development from construction and use by vehicles to maintenance affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.
