Book Description
As the world transitions from an industrial society to an information society, agriculture has undergone a dramatic transformation. Food production in the 20th century was transformed by three revolutions: first mechanical, then genetic, and finally chemical. Now, in the 21st century, agriculture is going through at least two more revolutions: an information technology revolution leading to precision farming, and a biotechnology revolution leading to genetically engineered crops. Organized by Harvard University's David Rockefeller Center for Latin American Studies with the collaboration of the Scientific Committee for Problems of the Environment, this interdisciplinary volume examines the impact of a variety of new technological, social, and economic trends on the rural environment.

Book Description
Tropical areas present ecological, cultural, and political problems that demand analysis that is distinct from general ecological analysis. The tropical environment is special in many ways, from the lack of a biological down season (winter), to generally poor soil conditions, to a reliance on traditional methods of agriculture in an undeveloped society. Presenting a broad range of approaches to agroecosystem analysis, this book addresses specific ecological issues associated with agricultural production, examines two case studies of agricultural transformation and its effect on biodiversity, and discusses key landscape relationships between agroecosystems, wildlife, and human disease.

Book Description
Describing all of Colombia's birds, Steven Hilty and William Brown bring together information on one of the world's largest avifaunas-nearly 1,700 species. Over half of all the species of birds in South America are included, thus making the book useful in regions adjacent to Colombia, as well as in the country itself. The primary purpose of the work is to enable observers to identify the birds of the region, but it also provides detailed species accounts and will serve as an important handbook and reference volume. Fifty-six lavish color plates, thirteen halftone plates, and ninety-nine line drawings in the text illustrate over 85% of the species, including most of the resident birds. Notes on the facing-page of each place, and range maps of 1,475 species, facilitate identification. Written with the field observer in mind, the text gives special attention to comparisons of similar species, transcriptions of voices, and comments on behavior, status, and habitat. It also provides ranges, breeding data, and references. Notes outline taxonomic problems and briefly describe species that eventually may be found in Colombia. Introductory chapters and photographs highlight Colombia's geography, climate, and vegetation, and discuss migration and conservation questions, and the history of Colombian ornithology. Appendices contain a large bibliography, a section on birding locations, and coverage of two of Colombia's far-flung island territories, Isla San Andr s and Providencia. Maps depicting vegetation zones, political boundaries, national parks, and the most text localities are included.

Book Description
The conventional approach to river protection has focused on water quality and maintaining some "minimum" flow that was thought necessary to ensure the viability of a river. In recent years, however, scientific research has underscored the idea that the ecological health of a river system depends not on a minimum amount of water at any one time but on the naturally variable quantity and timing of flows throughout the year. In Rivers for Life, leading water experts Sandra Postel and Brian Richter explain why restoring and preserving more natural river flows are key to sustaining freshwater biodiversity and healthy river systems, and describe innovative policies, scientific approaches, and management reforms for achieving those goals. Sandra Postel and Brian Richter: explain the value of healthy rivers to human and ecosystem health; describe the ecological processes that support river ecosystems and how they have been disrupted by dams, diversions, and other alterations; consider the scientific basis for determining how much water a river needs; examine new management paradigms focused on restoring flow patterns and sustaining ecological health; assess the policy options available for managing rivers and other freshwater systems; explore building blocks for better river governance. Sandra Postel and Brian Richter offer case studies of river management from the United States (the San Pedro, Green, and Missouri), Australia (the Brisbane), and South Africa (the Sabie), along with numerous examples of new and innovative policy approaches that are being implemented in those and other countries. Rivers for Life presents a global perspective on the challenges of managing water for people and nature, with a concise yet comprehensive overview of the relevant science, policy, and management issues. It presents exciting and inspirational information for anyone concerned with water policy, planning and management, river conservation, freshwater biodiversity, or related topics.

Book Description
Twenty years after the Convention on Biological Diversity (CBD) entered into force, the founding of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) in 2012 was the outcome of a long process of setting biodiversity issues at the top of the global environmental agenda. With contributions from more than a dozen well-renowned researchers in political science, law and sociology, this book analyzes IPBES functioning and challenges in terms of the knowledge selection process and actors involved. The book reveals that, through its conceptual framework, IPBES promotes a pluralistic view of nature that calls for a broadening of the disciplinary frontiers. It combines natural science and social science research and also includes indigenous and local knowledge. IPBES is considered to represent the institutionalization of a permanent knowledge assessment on biodiversity and is often referred to as an IPCC success story, constituting a new stage in global environmental governance. In analyzing the knowledge selection process for IPBES decision making, the book better situates IPBES within the biodiversity and global governance domain. It ultimately argues that the establishment of IPBES provides a new opportunity to coordinate the different international conventions (CBD, RAMSAR, CITES, etc.) and initiatives (international assessment of marine biology, scientific programs, funding, etc.).
