Information about appropriate technology available to developing countries is common. What is not often achieved is a flow of the actual technologies themselves between countries - and the IDEA Awards aim to stimulate this transfer of useful technology between needy people in different environments. This book consists of profiles of over 80 technical innovations in the field of development, which represent technologies submitted to the Innovation for Development Association for their 1990 awards. Five main subject areas are covered: water, energy, forestry, farming and fishing, and the criteria for judging the nominations were sustainability, self-reliance and socio-economic acceptance. The main purpose of this book is to disseminate knowledge of innovations which have been developed and tested in real environments with real needs, and in close contact with end-users. Most of the innovations presented have a full page each, some are illustrated, and all are accompanied by contacts of people and addresses. These 80 plus innovations will undoubtedly be as useful as the original hundred ("100 innovations for development") and having already proved their value once, should prove their use around the world.
