Sheep and wheat are the staples of dryland farms in the Mediterranean zone of the Northern Hemisphere. The commonly used dryland farming system introduced in the 1950s, however, is proving unsustainable. What is needed is an alternative system that is both environmentally sustainable and within the means of most farmers in the region. This book analyzes the quagmire of development on dryland farms to try to find some answers to these issues for scientists in agriculture and economics. | Sustainable Dryland Farming by Lynne Chatterton, Hardcover | Indigo Chapters
