The CRC Handbook of Alternative Cash Crops describes 128 crop plants that can be grown as alternatives to cultivated crops, such as tobacco, and narcotic crops, such as opium poppy. Material is presented in alphabetical order by genus and species and includes information on ecology, cultivation, harvesting, economics, and biotic factors. This book will be valuable to AID agents, domestic agricultural extension agents, and soil and crop professionals worldwide.

The bulk of the world’s tobacco is produced in low- and middle-income countries. In order to dissuade these countries from implementing policies aimed at curbing tobacco consumption (such as increased taxes, health warnings, advertising bans and smoke-free environments), the tobacco industry claims that tobacco farmers will be negatively affected and that no viable, sustainable alternatives exist. This book, based on original research from three continents, exposes the myths behind these claims.

This book presents the basic model of an agricultural household that underlies most of the case studies undertaken so far. The model assumes that households are price-takers and is therefore recursive. The decisions modeled include those affecting production and the demand for inputs and those affecting consumption and the supply of labor. Comparative results on selected elasticities are presented for a number of economies. The empirical significance of the approach is demonstrated in a comparison of models that treat production and consumption decisions separately and those in which the decisionmaking process is recursive. The book summarizes the implications of agricultural pricing policy for the welfare of farm households, marketed surplus, the demand for nonagricultural goods and services, the rural labor market, budget revenues, and foreign exchange earnings. In addition, it is shown that the basic model can be extended in order to explore the effects of government policy on crop composition, nutritional status, health, saving, and investment and to provide a more comprehensive analysis of the effects on budget revenues and foreign exchange earnings. Methodological topics, primarily the data requirements of the basic model and its extensions, along with aggregation, market interaction, uncertainty, and market imperfections are discussed. The most important methodological issues - the question of the recursive property of these models - is also discussed.

This publication capitalizes on the experience of scientists from the North Africa and Near East countries, in collaboration with experts from around the world, specialized in the different aspects of greenhouse crop production. It provides a comprehensive description and assessment of the greenhouse production practices in use in Mediterranean climate areas that have helped diversify vegetable production and increase productivity. The publication is also meant to be used as a reference and tool for trainers and growers as well as other actors in the greenhouse vegetables value chain in this region.
