Communication for Rural Innovation

Rethinking Agricultural Extension

By: Cees Leeuwis

This important book is the re-titled third edition of the extremely well received and widely used Agricultural Extension (van den Ban & Hawkins, 1988, 1996). Building on the previous editions, Communication for Rural Innovation maintains and adapts the insights and conceptual models of value today, while reflecting many new ideas, angles and modes of thinking concerning how agricultural extension is taught and carried through today. Since the previous edition of the book, the number and type of organisations that apply communicative strategies to foster change and development in agriculture and resource management has become much more varied and this book is aimed at those who use communication to facilitate change in agriculture and resource management. Communication for Rural Innovation is essential reading for process facilitators, communication division personnel, knowledge managers, training officers, consultants, policy makers, extension specialists and managers of agricultural extension or research organisations. The book can also be used as an advanced introduction into issues of communicative intervention at BSc or MSc level.

The Ethics of Cyberspace

By: Cees J Hamelink

In this book, Cees J Hamelink proposes an answer to - how should democratic societies organize cyberspace? - that puts human-rights, rather than profit, at the top of the agenda. He argues that conventional ethical approaches are all seriously flawed. There is a growing volume of moral rules, netiquettes and codes of conduct, but they are of little help in solving the moral dilemmas raised by the new technologies. In this book the author analyzes the inadeqacies of current global governance policies and structures that underpin them, and argues for standards which put justice, human security and freedom first.

Plant Nutrition of Greenhouse Crops

By: Cees Sonneveld,Wim Voogt

Greenhouse cultivation is noted for its high uptake of minerals, consistent climatic conditions, exclusion of natural precipitation and control of salt accumulation. Acknowledging that plant nutrition in greenhouse cultivation differs in many essentials from field production, this volume details specific information about testing methods for soils and substrates in a greenhouse environment. It does so while offering a universally applicable analysis. This is based on the composition of the soil and substrate solutions, methods for the interpretation of tissue tests, and crop responses on salinity and water supply in relation to fertilizer application. Fertilizer additions, related to analytical data of soil and substrate samples, are presented for a wide range of vegetable and ornamental crops. The subject is especially apt now as substrate growing offers excellent possibilities for the optimal use of water and nutrients, as well as the potential for sustainable production methods for greenhouse crops.
