Birleşmiş Milletler Gıda ve Tarım Örgütü (FAO), beslenme, gıda ve tarımla ilgili bilgileri toplamak, analiz etmek, yorumlamak ve yaymakla görevlidir. Bu bağlamda, FAO'nun yetki alanıyla ilgili konularda bir dizi veritabanı yayınlar ve bunların bilimsel ve araştırma amaçlı kullanımını teşvik eder. Open Data Licensing For Statistical Databases (İstatistik Veritabanları İçin Açık Veri Lisanslama) kapsamında öngörülen açıklık ve paylaşım ilkeleriyle tutarlı olarak ve FAO'nun yetkisiyle uyumlu şekilde, AQUASTAT'ın (FAO'nun Su ve Tarım Konusundaki Küresel Bilgi Sistemi) bir parçası olan Water Productivity Open Access Portal (WaPOR)'daki (Su Verimliliği Açık Erişim Portalı) veriler, kullanıcı topluluğuna ücretsiz olarak sunulur.
