Over the past two decades a quiet revolution has been taking place in the countryside of China where hundreds of millions of people have been lifted out of poverty. This book focuses on some of the practical actions and clever use of appropriate technologies which have been at the heart of this positive grassroots-driven change in rural Gansu Province. Key to this has been mobilizing the population and their expeditious use of rainwater harvesting both to dramatically improve crop yields and provide households with reliable domestic water supplies. Challenges such as lack of fuelwood have been overcome by the development of simple low-cost solar cookers; the construction of low-cost greenhouses allows for the collection of rainwater and its use in efficient drip irrigation systems. The real significance of this case study is that most of the approaches described are based on universal principles of sustainable development.This book is recommended reading for engineers, planners, staff of NGOs, academics and students in the water, energy, and agriculture sectors.
