The Globally Important Agricultural Heritage Systems (GIAHS) are living heritage systems inhabited by communities that maintain an intricate relationship with their territory. These evolving and resilient systems are characterized by remarkable agrobiodiversity, traditional knowledge, invaluable cultures, and landscapes, sustainably managed by farmers, herders, fisherfolk, and forest people in ways that support their livelihoods and food security. Through the Globally Important Agricultural Heritage Systems Programme, the Food and Agriculture Organization of the United Nations has designated 99 systems in 29 countries.
