Based on his stewardship work, for which he was awarded the 2019 Volvo Environment Prize, he wrote “Grassroots Stewardship: Sustainability Within Our Reach” to explore stewardship with a general audience. Stuart Chapin III, known to his friends as “Terry,” is an Alaskan ecologist who has written leading textbooks in ecosystem stewardship, ecosystem ecology, and plant physiological ecology. This book synthesizes advances in ecology with established theory to offer a complete survey of ecosystem pattern and process in the terrestrial environment.moreį. As human activity becomes an increasingly dominant factor in natural processes around the globe, landscape dynamics over time and space have become the focus of attention. This textbook outlines the central processes that characterize terrestrial ecosystems, tracing the flow of water, carbon, and nutrients from their abiotic origins to their cycles through plants, animals, and decomposer organisms. A The ecosystem approach to ecology treats organisms and the physical elements of their environment as components of a single, integrated system.
