Subject Rankings
National Institute of Water & Atmospheric Research Ltd (NIWA) Subject Rankings 2025
Agriculture and Forestry, Architecture and Design, Business and Management, Economics and Econometrics, Education, Engineering and Technology, History, Philosophy, Theology, Law, Medicine and Health Sciences, Natural Sciences, Social Sciences, Art and Humanities Scientist Rankings and Social Sciences and Humanities Scientist Rankings along with their 197 sub-branches, can be analyzed at global, national, and regional levels. You can also evaluate them based on the i10 index and citation numbers. As of Sep 21, 2024, rankings are according to the Total H Index. BETA VERSION: The subject field rankings for the world, regions, countries, and universities are currently in beta. This is due to the exclusion of (1.014.186) scientists categorized under 'others,' whose profiles cannot yet be determined, edited, or classified. As these fields are updated, the rankings will adjust accordingly. Please keep this in mind. See Also: [University Subject Rankings]
