Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Book Description
National information needs on forests have grown considerably in recent years, evolving from forest area and growing stock information to key aspects of sustainable forest management, such as the role of forests in the conservation of biodiversity and the provision of other ecosystem services. More recently, information on changes in carbon stocks, socio-economic aspects including the contribution to livelihoods and poverty reduction, governance and broader land use issues has become critical for national planning.

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
Contrary to conventional wisdom that equates rural economies with agriculture, rural residents in developing countries often rely heavily on activities other than farming for their income. Indeed, nonfarm work accounts for between one-third and one-half of rural incomes in the developing world. In recent years, accelerating globalization, increasing competition from large businesses, expanding urban markets for rural goods and services, and greater availability of information and communication technology have combined to expose rural nonfarm businesses to new opportunities as well as new risks. By examining these rapid changes in the rural nonfarm economy, international experts explore how the rural nonfarm economy can contribute to overall economic growth in developing countries and how the poor can participate in this rapidly evolving segment of the economy. The authors review an array of recent studies of the rural nonfarm economy in order to summarize existing empirical evidence, explore policy implications, and identify future research priorities. They examine the varied scale, structure, and composition of the rural nonfarm economy, as well as its relationship with agricultural and urban enterprises. And they address key questions about the role of public intervention in the rural nonfarm economy and how the rural poor can participate in and navigate the rapid transition underway in rural areas. The contributors offer new insights to specialists in rural development and to others interested in overall economic development.
