Ingrid Jacoba Visseren-Hamakers (born 3 February 1970) is a Dutch academic and politician of the Party for the Animals (PvdD). She is a professor of environmental policy at Radboud University Nijmegen. Her work focuses on global environmental governance, biodiversity, and sustainability transitions.[1] Since 2023, she has served as a member of the Senate.
Early life and education
Visseren-Hamakers was born on 3 February 1970 in Brummen, Gelderland.[2] She studied environmental and social sciences at Utrecht University, and business administration at Erasmus University Rotterdam.[2]
Career
Visseren-Hamakers held academic positions at Wageningen University and George Mason University in the United States, before joining Radboud University in 2019.[3] Between 2016 and 2019, she served as coordinating lead author for the global assessment report of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES).[3]
Her political career began in Rotterdam, where she was a member of the IJsselmonde borough council from 1998 to 2002, on behalf of GroenLinks.[3] From 2004 to 2007, she served in the party's executive board.[3] She later joined the Party for the Animals (PvdD), and was elected as a member of the Senate in the 2023 election. On 3 February 2025, she succeeded Niko Koffeman as leader of the PvdD Senate group.[4]
Visseren-Hamakers Group
On 10 November 2025, it was announced that Visseren-Hamakers had left the PvdD Senate group, forming her own independent group.[5] The split followed an internal dispute, after Niko Koffeman had resigned his party membership on 21 October 2025, citing dissatisfaction with the party's political direction.[6] He was supported by fellow senator Peter Nicolaï.[7] As a result, Koffeman and Nicolaï continued together under the party banner, while Visseren-Hamakers formed a separate group.[8] Despite the formal split, Visseren-Hamakers is regarded by the Party for the Animals as the sole legitimate representative of the party in the Senate.[8]
