Arjan is passionate about people and nature. He believes man is part of nature and likes to work towards a future where man and nature coincide. He started his career studying business administration and working for shipping multinational P&O Nedlloyd. After years of working as an expat he followed his heart for nature and changed course by doing a Masters in environmental management. As such he became a lobbyist for a Dutch non profit organisation aimed at greening the EU agricultural policies. After several years in Brussels he started as head of the water programme of WWF NL, where he focussed on restoration and protection of estuaries worldwide. He started a programme in the Netherlands, restoring natural dynamics in the delta and bringing back the sturgeon in the Netherlands. As delta advisor he managed several projects worldwide, for example leading to the reintroduction of Chinese river deer close to Shanghai. Arjan became director of the Waddenvereniging, a Dutch NGO protecting the Unesco Worldheritage Waddensea. Together with local population the Waddenvereniging managed to stop gas exploration plans in the area and Arjan had a successful lobby for changing the governance of the area. Arjan is particularly proud to have started the innovative Fish Migration River project on the lower Rhine. Implementation has been approved in Europe at a cost of 50 million euros. A big solution for a big problem, with the goal of restoring the great and crucial Rhine Swimway routes. The project made him so enthusiastic on the issue of fish migration that he did not hesitate when he was asked to manage the new World Fish Migration Foundation.
