Cultural landscapes are created by people, and used by people, but still decidedly rich in biodiversity, and in harmony with nature. The landscapes of fairy tales, without dragons. Socio-economic complexity on top of biological diversity is the challenge nature conservation faces in the context of cultural landscape. This book is an attempt to approach this complexity and provide a theoretical background as well as guidelines and examples for hands-on solutions. It draws on inputs from scientists, administrators, independent consultants and politicians from Europe and the United States. With a particular emphasis on agriculture it attempts to merge disciplines such as philosophy, law, planning, economics and conservation biology toward a common goal: nature conservation and the preservation of biological diversity in landscapes under the pressure of human usage.
There can be little doubt that there are truly colossal challenges associated with providing food, fibre and energy for an expanding world population without further accelerating already rapid rates of biodiversity loss and undermining the ecosystem processes on which we all depend. These challenges are further complicated by rapid changes in climate and its additional direct impacts on agriculture, biodiversity and ecological processes. There are many different viewpoints about the best way to deal with the myriad issues associated with land use intensification and this book canvasses a number of these from different parts of the tropical and temperate world. Chapters focus on whether science can suggest new and improved approaches to reducing the conflict between productive land use and biodiversity conservation. Who should read this book? Policy makers in regional, state and federal governments, as well as scientists and the interested lay public.
These proceedings contain papers on insect conservation biology that are classified under 3 themes: (1) the current status of insect conservation, and major avenues for progress and hindrances (6 papers); (2) insects as model organisms in conservation biology (6 papers); and (3) future directions in insect conservation biology (6 papers).
Seeking Sustainability in an Age of Complexity explains the difficulties of sustainability and why 'collapse' can occur. In the last twenty years the theory of complexity has been developed - complex systems science (CSS) speaks to natural systems and particularly to ecological, social and economic systems and their interaction. Due to the growing concern over the huge changes occurring in the global environment, such as climate change, deforestation, habitat fragmentation and loss of biodiversity, Graham Harris sets out what has been learned in an attempt to understand the implications of these changes and suggests ways to move forward. This book discusses a number of emerging tools for the management of 'unruly' complexity which facilitate stronger regional dialogues about knowledge and values, which will be of interest to ecologists, sociologists, economists, natural resource managers and scientists in State and local governments and those involved in water and landscape management.
In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.
Sustainable Life on Land, the fifteenth UN Sustainable Development Goal (SDG 15), calls for the protection, restoration and promotion of the sustainable use of terrestrial ecosystems. Among others, it requires societies to sustainably manage forests, halt and reverse land degradation, combat desertification, and halt biodiversity loss. Despite the fact that protection of terrestrial ecosystems is on the rise worldwide and forest loss has slowed, the recent IPBES report concluded that “nature is declining globally at rates unprecedented in human history”. Consequently, the United Nations General Assembly recently declared 2021–2030 the UN Decade on Ecosystem Restoration. There is no dou...
Thoroughly updated new edition of this undergraduate textbook examines environmental pollution from our homes to the global environment.
Mutualisms, interactions between two species that benefit both of them, have long captured the public imagination. Their influence transcends levels of biological organization from cells to populations, communities, and ecosystems. Mutualistic symbioses were crucial to the origin of eukaryotic cells, and perhaps to the invasion of land. Mutualisms occur in every terrestrial and aquatic habitat; indeed, ecologists now believe that almost every species on Earth is involved directly or indirectly in one or more of these interactions. Mutualisms are essential to the reproduction and survival of virtually all organisms, as well as to nutrient cycles in ecosystems. Furthermore, the key ecosystem s...
This publication contains a number of reports prepared for a high-level conference on issues relating to biological and landscape diversity in European agricultural policies, held in Paris in June 2002. The conference made recommendations to states and relevant organisations and provided input to policy work and programmes within the framework of the Convention on Biological Diversity, the Ministerial Conference on Environment for Europe , the Convention to Combat Desertification and the EU's Common Agricultural Policy and national policy developments.
This book is the first comprehensive, global treatment of landesque capital, a widespread concept used to understand anthropogenic landscapes that serve important economic, social, and ritual purposes. Spanning the disciplines of anthropology, human ecology, geography, archaeology, and history, chapters combine theoretical rigor with in-depth empirical studies of major landscape modifications from ancient to contemporary times. They assess not only degradation but also the social, political, and economic institutions and contexts that make sustainability possible. Offering tightly edited, original contributions from leading scholars, this book will have a lasting influence on the study long-term human-environment relations in the human and natural sciences.
