There have been significant changes in sea level over the past two million years, and a complete understanding of natural cycles of change as well as anthropogenic effects is imperative for future global development. This book reviews the history of research into these sea-level changes and summarises the methods and analytical approaches used to interpret evidence for sea-level changes. It provides an overview of changing climates during the Quaternary, examines processes responsible for global variability of sea-level records, and presents detailed reviews of sea-level changes for the Pleistocene and Holocene. The book concludes by discussing current trends in sea levels and likely future sea-level changes. This is an important and authoritative resource for academic researchers and graduate and advanced undergraduate students working in tectonics, stratigraphy, geomorphology, physical geography, environmental science and other aspects of Quaternary studies.
This innovative interdisciplinary study focuses on the history, science, and policy of tree planting and water conservation in South Africa. South Africa’s forestry sector has sat—often controversially—at the crossroads of policy and scientific debates regarding water conservation, economic development, and biodiversity protection. Bennett and Kruger show how debates about the hydrological impact of exotic tree planting in South Africa shaped the development of modern scientific ideas and state policies relating to timber plantations, water conservation, invasive species control, and biodiversity management within South Africa as well as elsewhere in the world. Forestry and Water Conservation in South Africa shows how scientific research on the impact of exotic and native vegetation led to the development of a comprehensive national policy for conserving water, producing timber, and protecting indigenous species from invasive alien plants. Policies and laws relating to forests and water began to change in the late 1980s and early 1990s as a result of political and administrative changes within South Africa. This book suggests that the country’s contemporary policies towards timber plantations, guided by the National Water Act of 1998, need to be reconsidered in light of the authors’ findings. Bennett and Kruger also call for more interdisciplinary research and greater emphasis on integrated policies and management plans for forestry, invasive alien plants, water conservation, and biodiversity preservation.
