Book Description
Community-oriented conservation of natural resources and promotion and protection of trees in drylands are examples to deal with climatic adversities. This book provides knowledge on climatic, ecological, social and economic condition of dry areas and lay out approaches and strategies to restore degraded lands. There are 15 chapters and first five deals with physiography of Rajasthan, drylands ecology, problems of land degradation, its economic evaluation and the approaches and strategies of restoration and rehabilitation. Next two chapters describe the problems of sand drift, salinity, water logging and effluent inflicted areas and strategies to control them. Chapters 8-10 deal with seed production, quality planting materials, genetic improvement, propagation and planting techniques. Chapters 11-12 describe methods of rain water harvesting and irrigation, and resources conservation for seed sowing and favouring regeneration and successions. Effective management of pests/diseases in nurseries and plantation, growth and yield prediction equations and models, and people's perception and participation in managing forest resources have been described in last 3 chapters. Purpose of this publication is to strengthen the forest functionaries and readers with wide ranging knowledge on land degradation, desertification and eco-biology of drylands; and methods to restore and rehabilitate degrading forest (lands) to increase forest cover, enhance resilience and people livelihoods and improve environmental conditions. Academician, researchers, forest managers, non-government organizations, extension agents and environmentalists can use it in developing, conserving and managing drylands ecosystems for its long lasting beneficial effects. This book is also useful to policy makers in effective planning of restoring, protecting and conserving dryland's ecological and socioeconomic services.

Book Description
The Wind River Experimental Forest has been called the cradle of forestry in the Pacific Northwest. Located in the Gifford Pinchot National Forest in southwest Washington, the forest is a nexus of groundbreaking discoveries in forest genetics and ecology, and is one of more than seventyfive Forest Service landscapes across the U.S. devoted to forest and range research. Forest of Time follows one hundred years of forest science at Wind River, as social and scientific changes transformed the twentieth century and the Pacific Northwest forest itself. The Forest Service began research at Wind River in 1908 to learn the secrets of the giant Douglas fir. During the course of the century, generations of scientists studied the forest from different angles, and their conclusions changed through time. Initially, Wind River scientists saw the region in need of protec tion from fire and careless logging. They saw scorched, cutover land that required replanting. Later they saw the forest in need of improvement, needing to be freed from pests and unprofitable s pecies and replaced with thrifty, fastgrowing plantations. Wind River soon became a laboratory where foresters from around the world came to learn how to grow the best possible lumber in the shortest amount of time. As plantations replaced natural forest stands, scientists came to Wind River to explore the complexity of oldgrowth forest ecosystems. And today, Wind River is the center of a twentyfirst century exploration of forest canopies and the global connec tion between forests and atmos phere. In Forest of Time, Margaret Herring and Sarah Greene show readers how science grows and changes in unexpec ted ways, much like a forest through time. It is a story of discovery and blindness, of opportunities taken and missed, in a forest dedicated to longterm research.

Book Description
Principles of Soil and Plant Water Relations, 2e describes the principles of water relations within soils, followed by the uptake of water and its subsequent movement throughout and from the plant body. This is presented as a progressive series of physical and biological interrelations, even though each topic is treated in detail on its own. The book also describes equipment used to measure water in the soil-plant-atmosphere system. At the end of each chapter is a biography of a scientist whose principles are discussed in the chapter. In addition to new information on the concept of celestial time, this new edition also includes new chapters on methods to determine sap flow in plants dual-probe heat-pulse technique to monitor water in the root zone. - Provides the necessary understanding to address advancing problems in water availability for meeting ecological requirements at local, regional and global scales - Covers plant anatomy: an essential component to understanding soil and plant water relations
