Director Digna Sinke, author of several fascinating documentaries about her native Zeeland, in the southwest of the Netherlands (Tiengemeten, Nature and Nostalgia), returns in this film to his favorite subject: the complex relations between economic and environmental interests in a country where nature is scarce. In 2005, the Netherlands and Belgium signed the so-called Western Scheldt Treaty, making it possible to deepen this arm of the sea, which is vital for the economy of Antwerp. At the same time, on the Dutch side, the Hedwigepolder had to be “de-polderized” and thus returned to nature. Ten years later, the treaty is still not implemented. Sinke reveals the political and economic interests of this case.
