Perhaps less than 10 percent of the world's sheep have hair coats instead of wool fleeces, but as an animal resource, these sheep are important far out of proportion to their numbers. Hair coats provide an advantage in the face of the heat, humidity, and other stresses of the tropics. Small in body size, early to mature, and often highly prolific,

African Ethnobotany in the Americas provides the first comprehensive examination of ethnobotanical knowledge and skills among the African Diaspora in the Americas. Leading scholars on the subject explore the complex relationship between plant use and meaning among the descendants of Africans in the New World. With the aid of archival and field research carried out in North America, South America, and the Caribbean, contributors explore the historical, environmental, and political-ecological factors that facilitated/hindered transatlantic ethnobotanical diffusion; the role of Africans as active agents of plant and plant knowledge transfer during the period of plantation slavery in the Americas; the significance of cultural resistance in refining and redefining plant-based traditions; the principal categories of plant use that resulted; the exchange of knowledge among Amerindian, European and other African peoples; and the changing significance of African-American ethnobotanical traditions in the 21st century. Bolstered by abundant visual content and contributions from renowned experts in the field, African Ethnobotany in the Americas is an invaluable resource for students, scientists, and researchers in the field of ethnobotany and African Diaspora studies.

Sustainable management of the world's livestock genetic diversity is of vital importance to agriculture, food production, rural development and the environment. "The State of the World's Animal Genetic Resources for Food and Agriculture" is the first global assessment of these resources. Drawing on 169 Country Reports, contributions from a number of international organizations and 12 specially commissioned thematic studies, it presents an analysis of the state of agricultural biodiversity in the livestock sector - origins and development, uses and values, distribution and exchange, risk status and threats - and of capacity to manage these resources - institutions, policies and legal frameworks, structured breeding activities and conservation programmes. Needs and challenges are assessed in the context of the forces driving change in livestock production systems. Tools and methods to enhance the use and development of animal genetic resources are explored in sections on the state of the art in characterization, genetic improvement, economic evaluation and conservation. The main findings of the report are summarized in "The State of the World's Animal Genetic Resources for Food and Agriculture - in brief," of which the Arabic, Chinese, English, French, Russian and Spanish versions can be found on the attached CD-ROM and are also available separately in printed form. As well providing a technical reference document, the country-based preparation of "The State of the World" has led to a process of policy development and a "Global Plan of Action for Animal Genetic Resources," which once adopted, will provide an agenda for action by the international community. Published also in French.
