For centuries, farmers, herders, fishers and foresters have developed diverse and locally adapted agricultural systems managed with time tested, ingenious techniques. These practices have resulted in a vital combination of social, cultural, ecological and economic services to humankind. “Globally Important Agricultural Heritage Systems” (GIAHS) are outstanding landscapes of aesthetic beauty that combine agricultural biodiversity, resilient ecosystems and a valuable cultural heritage. Located in specific sites around the world, they sustainably provide multiple goods and services, food and livelihood security for millions of small-scale farmers.
