DOWNLOAD EBOOKProvides a complete guide to the study, design, construction and management of landslide and slope engineering measures for mountain roads, with emphasis on low-cost. The geographical focus is on the tropics and sub-tropics, but is also highly relevant to other regions where heavy rain, steep slopes and weak soils and rocks combine to create slope instability. The causes and mechanisms of landslides are described, and the hazards they pose to mountain roads are illustrated. Methods of desk study, field mapping and ground investigation are reviewed and illustrated, with emphasis on geomorphological and engineering geological techniques. The design and construction of alignments, earthworks, drainage, retaining structures, the stabilization of soil slopes and rock slopes, and the control of erosion on slopes and in streams covered. Slope management as part of road maintenance and operation is reviewed, and procedures for risk assessment and works prioritization are described.

DOWNLOAD EBOOKThe purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

DOWNLOAD EBOOKAll phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.

DOWNLOAD EBOOKSince the 1980s, and especially since the Rio Earth Summit in 1992, there has been a substantial extension in the adoption and use of Environmental Assessment (EA) procedures in developing countries and countries in transition (low and middle income countries). However, few existing texts in environmental assessment or development studies have reflected this trend sufficiently, until this publication. Divided into two main parts: * EA Principles, Processes and Practice. * Country and Institutional Studies of EA Procedures and Practice. This book explains the essentials of environmental impact association in the context of developing countries and assesses its importance to both developed and developing countries.

DOWNLOAD EBOOKWhen the going gets rough, the rough . . . start raising their own food. In the first full-color guide of its kind, author and small farm owner Laura Childs reveals exactly what it takes to start raising your own animals, including chickens, geese, goats, sheep, pigs, and cows. Childs discusses what you can expect to harvest from your animals—from eggs to milk to meat to wool—based on her own real-life experiences. Whether you want to raise a few chickens for eggs alone, try your hand at a few goats with the aim to make your own cheese, or are looking to sustain your family and make some extra money from raising and selling beef, this is the book for you. Childs offers general information for each breed and animal, from how to get started to what to feed and where to house the animals. This invaluable guide is the perfect first book for anyone interested in starting a backyard barnyard or a small farm—or simply dreaming about the idea.
