Book Description
The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.

Book Description
This text is a history of the world's oldest global conservation body - the World Conservation Union, established in 1948 as a forum for governments, non-governmental organizations and individual conservationists. The author draws on unpublished archives to reveal the often turbulent story of the IUCN and its achievements in, and influence on, conservation and environmental policy worldwide - establishing national parks and protected areas and defending threatened species.

Defending the Land of the Jaguar
Author: Lane Simonian
Publisher: University of Texas Press
ISBN: 0292776918
Category : Nature
Languages : en
Pages : 343
Book Description
Mexican conservationists have sometimes observed that it is difficult to find a country less interested in the conservation of its natural resources than is Mexico. Yet, despite a long history dedicated to the pursuit of development regardless of its environmental consequences, Mexico has an equally long, though much less developed and appreciated, tradition of environmental conservation. Lane Simonian here offers the first panoramic history of conservation in Mexico from pre-contact times to the current Mexican environmental movement. He explores the origins of conservation and environmental concerns in Mexico, the philosophies and endeavors of Mexican conservationists, and the enactment of important conservation laws and programs. This heretofore untold story, drawn from interviews with leading Mexican conservationists as well as archival research, will be important reading throughout the international community of activists, researchers, and concerned citizens interested in the intertwined issues of conservation and development.

Diseases of Banana, Abacá, and Enset
Author: David Robert Jones
Publisher: Oxford University Press, USA
ISBN: 9780851993553
Category : Abaca (Plant)
Languages : en
Pages : 0
Book Description
This book provides a comprehensive guide to the large number of diseases, disorders and injuries that can cause severe economic losses to banana, plantain, abaca and enset crops. Most of the diseases are described and illustrated in color, making the book valuable as a diagnostic tool. It also provides information on the fungi, bacteria, viruses, nematodes and abiotic factors involved in the diseases/disorders described. Information is provided on the origin and classification of banana, the safe movement of Musa germplasm and banana breeding, including possibilities for genetic engineering for disease resistance.

Nutrient Cycling in Forest Ecosystems
Author: Robert G. Qualls
Publisher:
ISBN: 9783039368013
Category :
Languages : en
Pages : 218
Book Description
The long-term productivity of forest ecosystems depends on the cycling of nutrients. The effect of carbon dioxide fertilization on forest productivity may ultimately be limited by the rate of nutrient cycling. Contemporary and future disturbances such as climatic warming, N-deposition, deforestation, short rotation sylviculture, fire (both wild and controlled), and the invasion of exotic species all place strains on the integrity of ecosystem nutrient cycling. Global differences in climate, soils, and species make it difficult to extrapolate even a single important study worldwide. Despite advances in the understanding of nutrient cycling and carbon production in forests, many questions remain. The chapters in this volume reflect many contemporary research priorities. The thirteen studies in this volume are arranged in the following subject groups: • N and P resorption from foliage worldwide, along chronosequences and along elevation gradients; • Litter production and decomposition; • N and P stoichiometry as affected by N deposition, geographic gradients, species changes, and ecosystem restoration; • Effects of N and P addition on understory biomass, litter, and soil; • Effects of burning on soil nutrients; • Effects of N addition on soil fauna.
