Land Use Changes Involving Forestry in the United States

Book Description
About two-thirds (504 million acres) of the Nation's forests are classed as timberland, productive forests capable of producing 20 cubic feet per acre of industrial wood annually and not legally reserved from timber harvest. The USDA's 1997 National Resource Inventory shows that, nationally, 11 million acres of forest, cropland, and open space were converted to urban and other developed uses from 1992 to 1997, as the national rate of urbanization increased notably compared to the 1982-92 period. Forest land was the largest source of land converted to developed uses such as urbanization. Urban and other developed areas are projected to continue to grow substantially, in line with a projected U.S. population increase of more than 120 million people over the next 50 years, with population growth occurring the fastest in the West and South. Projected increases in population and income will, in turn, increase demands for use of land for residential, urban, transportation, and related uses. An overall net loss in forest area in the United States since the early 1950s has been due to a combination of factors, but in more recent decades has been primarily due to conversion to urban and developed uses. Total forest area in the United States is projected to decrease by approximately 23 million acres by 2050, a 3-percent reduction from the 1997 forest area. Consistent with the projected slow net decline in U.S. forestland area, private timberland area is likewise projected to decline. Total area of U.S. private timberland is projected to decline by 4 percent by 2050. Industry timberland is projected to decrease by 3.0 percent by 2050, whereas timberland area on nonindustrial private lands is projected to decrease by 4.4 percent.

Cross-sectoral Policy Developments in Forestry
Author: Yves C. DubéPublisher: CABI
ISBN: 1845932501
Category : Technology & Engineering
Languages : en
Pages : 282
Book Description
This book, containing 31 chapters grouped into two parts, provides rich and multi-faceted documentation of current progress being made in creating the political, economic and social conditions indispensable for sustainable and multi-functional use of forest resources, and notes the obstacles that needs to be removed to reach this goal. The first part (chapters 1-9) introduces general and global aspects that have to be considered in the context of cross sectoral policy coordination. This include discussions on the impact of external shocks such as a sudden oil price increase on forest management, the impact of energy or trade policies on global wood markets and the role of decentralization in integrating multiple demands on forests. The second part of the book deals with regional, national and local issues of cross-sectoral policy linkages. The chapters on Africa (chapters 10-15) focus largely on the improvement of land management practices such as agroforestry, land tenure and gender issues, more integrative policies in promoting reforestation and afforestation, multiple stakeholder planning processes and external policy impacts in protecting and managing Miombo forests. In Asia (chapters 16-20), important subjects appearing in several chapters are the need to develop environmental and economic accounts for forestry, and to demonstrate more clearly the great importance of non-timber forest product linkages, road construction and population effects of forest conversion, community forest management contributions to the local and national economy, and cross-sectoral policy links in the development of mountainous areas are other issues addressed. In the Europe part (chapters 21-24); both environmental problems as well as strong trends towards developing a competitive forest and wood-processing sector determine public policy development to a considerable extent. This can be seen from leading policy scenarios that have been identified from the changes in perceptions with regard to the forest sector and from the policy issues at national level that are presented. A somewhat similar pattern of competing policy demands between resource use, industrial expansion and strong environmental demands emerges from the contributions dealing with the Americas (chapters 25-31). These chapters contain the experiences of the USA in cross-sectoral impact analysis, the lessons to be learned from the long and confliction history in managing the national forests, as well as from the resource conflicts described between forestry uses, oil and gas development and environmental protection in the boreal regions of Canada.

Book Description
"This conference brought together scientists and managers from federal, state, and local agencies, along with private-sector interests, to examine key concepts involving sustainable ecological systems, and ways in which to apply these concepts to ecosystem management. Session topics were: ecological consequences of land and water use changes, biology of rare and declining species and habitats, conservation biology and restoration ecology, developing and applying ecological theory to management of ecological systems and forest health, and sustainable ecosystems to respond to human needs. A plenary session established the philosophical and historical contexts for ecosystem management."--Title page verso.

Book Description
The private working land base of America's forests is being converted to developed uses, with implications for the condition and management of affected private forests and the watersheds in which they occur. The Forests on the Edge project seeks to improve understanding of the processes and thresholds associated with increases in housing density in private forests and likely effects on the contributions of those forests to timber, wildlife, and water resources. This report, the first in a series, displays and describes housing density projections on private forests, by watershed, across the conterminous United States. An interdisciplinary team used geographic information system (GIS) techniques to identify fourth-level watersheds containing private forests that are projected to experience increased housing density by 2030. Results indicate that some 44.2 million acres (over 11 percent) of private forests--particularly in the East, where most private forests occur--are likely to see dramatic increases in housing development in the next three decades, with consequent impacts on ecological, economic, and social services. Although conversion of forest land to other uses over time is inevitable, local jurisdictions and states can target efforts to prevent or reduce conversion of the most valuable forest lands to keep private working forests resilient and productive.
