Persyaratan Penggunaan
Persyaratan Penggunaan
Food and Agriculture Organization of the United Nations (FAO) diberi mandat untuk mengumpulkan, menganalisis, menafsirkan, dan menyebarkan informasi terkait nutrisi, makanan, dan pertanian. Dalam hal ini, FAO memublikasikan sejumlah database tentang topik yang terkait dengan mandatnya, dan mendorong penggunaan database tersebut untuk tujuan ilmiah dan penelitian. Sesuai dengan prinsip keterbukaan dan berbagi yang diusulkan dalam Open Data Licensing For Statistical Databases, dan sesuai dengan mandat FAO, data dari Water Productivity Open Access Portal (WaPOR), sebagai bagian dari AQUASTAT - Sistem Informasi Global FAO tentang Air dan Pertanian, tersedia secara gratis untuk komunitas pengguna.
