Book excerpt: This timely two-volume compendium, Sustainable Horticulture, addresses the most important topics facing horticulture around the world today. The volumes cover a wide range of topical issues and trends in sustainable horticulture today: Volume 1: Diversity, Production, and Crop Improvements, and Volume 2: Food, Health, and Nutrition. Global food demand is expected to be double by 2050, while at the same time the production environment and natural resources are continually shrinking and deteriorating due to many complex factors. Horticulture, a major sector of agriculture, is vital to enhancing crop production and productivity in parity with agricultural crops to meet the emerging food demand. Implementing sustainable models of crop production is really an enormous endeavor. Promising technologies and management options are needed to increase productivity to meet the growing food demand despite deteriorating production environments.
