Landscape Boundaries

The emergence of landscape ecology during the 1980s represents an impor tant maturation of ecological theory. Once enamored with the conceptual beauty of well-balanced, homogeneous ecosystems, ecologists now assert that much of the essence of ecological systems lies in their lumpiness. Patches with differing properties and behaviors lie strewn across the land scape, products of the complex interactions of climate, disturbance, and biotic processes. It is the collective behavior of this patchwork of eco systems that drives pattern and process of the landscape. is not an end point This realization of the importance of patch dynamics in itself, however. Rather, it is a passage to a new conceptual framework, the internal workings of which remain obscure. The next tier of questions includes: What are the fundamental pieces that compose a landscape? How are these pieces bounded? To what extent do these boundaries influence communication and interaction among patches of the landscape? Will con sideration of the interactions among landscape elements help us to under stand the workings of landscapes? At the core of these questions lies the notion of the ecotone, a term with a lineage that even predates ecosystem. Late in the nineteenth century, F. E. Clements realized that the transition zones between plant communi ties had properties distinct from either of the adjacent communities. Not until the emergence of patch dynamics theory, however, has central signif icance of the ecotone concept become apparent.

What have cultural anthropologists, historical geographers, landscape ecologists and environmental artists got in common? Along with eight other disciplines, from domains as diverse as planning and design, the arts and humanities as well as the social and natural sciences, they are all fields of importance to the theory and practice of landscape architecture. In the context of the EU funded LE:NOTRE Project, carried out under the auspices of ECLAS, the European Council of Landscape Architecture Schools, international experts from a wide range of related fields were asked to reflect, each from their own perspective, on the interface between their discipline and landscape architecture. The resulting insights presented in this book represent an important contribution to the development the discipline of landscape architecture, as well as suggesting new ways in which future collaboration can help to create a greater interdisciplinary richness at a time when the awareness of the importance of the landscape is growing across a wide range of disciplines. Exploring the Boundaries of Landscape Architecture is the first systematic attempt to explore the territory at the boundaries of landscape architecture. It addresses academics, professionals and students, not just from landscape architecture but also from its neighbouring discipline, all of whom will benefit from a better understanding their areas of shared interest and the chance to develop a common language with which to converse.

If the body of knowledge of a profession is a living landscape of practice, then our personal experience of learning can be thought of as a journey through this landscape. Within Learning in Landscapes of Practice, this metaphor is further developed in order to start an important conversation about the nature of practice knowledge, identity and the experience of practitioners and their learning. In doing so, this book is a pioneering and timely exploration of the future of professional development and higher education. The book combines a strong theoretical perspective grounded in social learning theories with stories from a broad range of contributors who occupy different locations in their own landscapes of practice. These narratives locate the book within different contemporary concerns such as social media, multi-agency, multi-disciplinary and multi-national partnerships, and the integration of academic study and workplace practice. Both scholarly, in the sense that it builds on prior research to extend and locate the concept of landscapes of practice, and practical because of the way in which it draws on multiple voices from different landscapes. Learning in Landscapes of Practice will be of particular relevance to people concerned with the design of professional or vocational learning. It will also be a valuable resource for students engaged in higher education courses with work-based elements.

We live in a changing world; one in which there is much concern and discussion about the topics of global change, loss of biodiversity, and increasing threats to the sustainability of ecosystems. The effects these changes may have on the environment have lead governments and sCientists to make predictions as to how soon changes might occur, where, and with what impact for large and small regions of the Earth. Along with this concern for change in various regions has come the need to understand the role of boundaries between these regions and between landscape elements. Much previous ecological research has dealt with processes within relatively homogeneous landscape units or even the collective characteristics of a composite landscape. Now, however, there is an appreciation that abiotic and biotic components move across heterogeneous landscapes and that the boundaries between these units take on important control functions in this dynamic spatial system. Furthermore, landscape boundaries (or ecotones) are important not only in satisfying life-cycle needs of many organisms, but generally are characterized by high biological diversity.

Every piece of land, no matter how remote or untrammeled, has a boundary. While sometimes boundary lines follow topographic or biological features, more often they follow the straight lines of political dictate and compromise. Administrative boundaries nearly always fragment a landscape, resulting in loss of species that must disperse or migrate across borders, increased likelihood of threats such as alien species or pollutants, and disruption of natural processes such as fire. Despite the importance and ubiquity of boundary issues, remarkably little has been written on the subject.Stewardship Across Boundaries fills that gap in the literature, addressing the complex biological and socioeconomic impacts of both public and private land boundaries in the United States. With contributions from natural resource managers, historians, environmentalists, political scientists, and legal scholars, the book:develops a framework for understanding administrative boundaries and their effects on the land and on human behavior examines issues related to different types of boundaries -- wilderness, commodity, recreation, private-public presents a series of case studies illustrating the efforts of those who have cooperated to promote stewardship across boundaries synthesizes the broad complexity of boundary-related issues and offers an integrated strategy for achieving regional stewardshi.Stewardship Across Boundaries should spur open discussion among students, scientists, managers, and activists on this important topic. It demonstrates how legal, social, and ecological conditions interact in causing boundary impacts and why those factors must be integrated to improve land management. It also discusses research needs and will help facilitate critical thinking within the scientific community that could result in new strategies for managing boundaries and their impacts.

This classic work is a comprehensive treatment of the world’s political frontiers and boundaries, and includes sections on boundaries in the air as well as chapters treating the subject in a regional manner, covering the continents in terms of the evolution of boundaries.

International frontiers and boundaries separate land, rivers and lakes subject to different sovereignties. Frontiers are zones of varying widths and they were common many centuries ago. By 1900 frontiers had almost disappeared and had been replaced by boundaries that are lines. The divisive nature of frontiers and boundaries has formed the focus of inter-disciplinary studies by economists, geographers, historians, lawyers and political scientists. Scholars from these disciplines have produced a rich literature dealing with frontiers and boundaries. The authors surveyed this extensive literature and the introduction reveals the themes which have attracted most attention. Following the introduction the book falls into three sections. The first section deals systematically with frontiers, boundary evolution and boundary disputes. The second section considers aspects of international law related to boundaries. It includes chapters dealing with international law and territorial boundaries, maps as evidence of international boundaries and river boundaries and international law. The third section consists of seven regional chapters that examine the evolution of boundaries in the Americas, the Middle East, Africa, Asia, Europe, islands off Southeast Asia and Antarctica.
