Working the Sahel
Drawing on four years of field research, the authors look at how farmers manage biological resources, crop and non-crop biodiversity, soil fertility, and transform the landscape through agricultural intensification.
Fuzzy Database Modeling
Some recent fuzzy database modeling advances for the non-traditional applications are introduced in this book. The focus is on database models for modeling complex information and uncertainty at the conceptual, logical, physical design levels and from integrity constraints defined on the fuzzy relations. The database models addressed here are; the conceptual data models, including the ExIFO and ExIFO2 data models, the logical database models, including the extended NF2 database model, fuzzy object-oriented database model, and the fuzzy deductive object-oriented database model. Integrity constraints are defined on the fuzzy relations are also addressed. A continuing reason for the limited adoption of fuzzy database systems has been performance. There have been few efforts at defining physical structures that accomodate fuzzy information. A new access structure and data organization for fuzzy information is introduced in this book.
Anthropology and Development
This book re-establishes the relevance of mainstream anthropological (and sociological) approaches to development processes and simultaneously recognizes that contemporary development ought to be anthropology‘s principal area of study. Professor de Sardan argues for a socio-anthropology of change and development that is a deeply empirical, multidimensional, diachronic study of social groups and their interactions. The Introduction provides a thought-provoking examination of the principal new approaches that have emerged in the discipline during the 1990s. Part I then makes clear the complexity of social change and development, and the ways in which socio-anthropology can measure up to the challenge of this complexity. Part II looks more closely at some of the leading variables involved in the development process, including relations of production; the logics of social action; the nature of knowledge; forms of mediation; and ‘political‘ strategies.
Agroforestry - The Future of Global Land Use
This volume contains a solid body of the current state of knowledge on the various themes and activities in agroforestry worldwide. It is organized into three sections: the Introduction section consists of the summaries of six keynote speeches at the 2nd World Congress of Agroforestry held in Nairobi, Kenya, in 2009; that is followed by two sections of peer-reviewed thematic chapters grouped as “Global Perspectives” (seven chapters) and “Regional Perspectives” (eleven chapters), authored by professional leaders in their respective agroforestry-related fields worldwide. A total of 130 professionals from institutions in 33 countries in both developing and the industrialized temperate regions of the world contributed to the book as chapter authors and/or reviewers. Thus, the book presents a comprehensive and authoritative account of the global picture of agroforestry today.

Producer organisations and market chains
"The role of producer organizations in market chains has received increasing attention in recent years, both from governments and donors. In order to lower transaction costs, markets demand that smallholder farmers operate in an organized manner. However, though the policy openings for support seem promising, smallholder market access through farmer-led economic organisations is not easy. This book presents various approaches to support producer organisations in terms of providing economic services to their members, with a focus on developing countries. Markets are increasingly fragmented in value chains that link farmers with specific processors, retailers and consumer segments. Several con...

Uncertainty in Knowledge Bases
One out of every two men over eigthy suffers from carcinoma of the prostate.It is discovered incidentally in many patients with an alleged benign prostatic hyperplasia. In treating patients, the authors make clear that primary radical prostatectomy is preferred over transurethral resection due to the lower complication rate.
