"Evaluation (or assessment) of impact is generally regarded as an essential part of the project cycle, and is already well known and widely used in many disciplines - for example, environmental and social sciences, social psychology - and there is increasing evidence of its application to agricultur ... al research. The same pressures as are being felt in agricultural research apply in agricultural information: new technology, in the form of information and communication technologies (ICTs) is increasing the ability to access, collect, process and generate information, but there is also pressure to justify investment, and to demonstrate results (benefits). However, while the 'information/knowledge' culture may be burgeoning due to new ICTs, neither the methodology nor the culture of information impact studies is yet fully developed. There are as yet few methodologies and applications relating to information management in developing countries, and even fewer which have been or could be applied specifically to agricultural information management. This selective review seeks to engender wider knowledge, acceptance and application of evaluation in the field of agricultural information management by showing how it has been approached in other disciplines, in agricultural research, and most recently in information science and management, with some key examples relating to information management in developing countries. Finally, to give some indication of how it works in practice, some recent examples as applied to information management in developing countries are summarised as case studies."
