Nature : Trees & Forests

Over the last five decades pesticides have undoubtedly helped to increase agricultural production and control vectors of disease, however the environmental impact of long term agro-chemical use has been cause for concern along with the effects on human health. In Pesticides; Health, Safety and the Environment, Graham Matthews begins by looking at the developmental history of pesticides, and how crop protection was achieved before they were in use, how pesticides are registered for use and what happens to pesticides in food and the environment. Pesticide application and operator safety is investigated and the future of pesticides in light of the development of genetically modified crops is explored. Collecting together the most recent research in the area in a single volume, Pesticides: Health, Safety and the Environment is a vital resource for agricultural scientists, agronomists, plant scientists, plant pathologists, entomologists, environmental scientists, public health personnel, toxicologists, crop protection personnel and all those involved in the agrochemical industry and government pesticide registration and legislation. more...

The root system is a vital part of the plant and therefore understanding roots and their functioning is key to agricultural, plant and soil scientists.In Plant Roots Professor Peter Gregory brings together recent developments in techniques and an improved understanding of plant and soil interactions to present a comprehensive look at this important relationship, covering:. Root response to, and modification of, soils. Genetic control of roots' responses to the environment. Use of modern techniques in imaging, molecular biology and analytical chemistry. Practical exploitation of root characters. This book will be a vital tool for plant, crop, soil and agricultural scientists, plant physiologists, environmental scientists, ecologists and hydrologists. It will be a valuable addition to libraries in universities, agricultural colleges and research establishments where these subjects are studied and taught. more...

Long-range models that include product and resource detail are essential to meaningful analysis of both industry and resource sustainability. Taking this as its central argument, this book provides essential reading to anyone interested in projecting the future of either the forest products market and/or the forest resource conditions. It is aimed at policy makers, model builders, researchers and graduate students who are building or using forest sector models, as well as at forest industry managers and analysts. While focusing on a specific modeling system ??? the US Timber Assessment models ??? the authors highlight the general elements that might comprise a forest-sector market model of any country or region. Approaches to policy analysis are also general and equally applicable to both national and multi-national forest policy development outside the US ??? particularly in relation to on-going efforts to formulate national programs of sustainable forestry. The text provides literature surveys on relevant modeling issues and policy concerns, and demonstrates the application of the modeling system using a ???base case??? 50 year projection and a small set of scenarios to illustrate, for example, the effects of changes in public harvest policies, global change, variations in investments in silviculture, and globalization. Darius Adams and Richard Haynes are widely recognized as leading experts in the forest sector modeling field. more...
