Book Description
This publication deals with key issues in land tenure, especially as they relate to food insecurity and rural development situations. Land tenure issues are frequently ignored in rural development interventions, with often long-lasting, negative results. This guide is designed to assist technical officers in governments and civil society in understanding why and how land tenure issues should be considered in rural development projects. It analyses important contexts such as environmental degradation, gender discrimination, and conflicts, where land tenure is currently of critical concern.

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.
