For centuries the Dutch have focused on the drainage of water. As the population grew, more and more land got drained to increase the landscape. Amsterdam was originally a peat land just like the rest of our country. However, due to the increasing drought, the focus has shifted to retaining water in our landscapes. After all, peatlands preserve great biodiversity and store Co2 for both longer and larger quantities than a forest does.

Otterdam explores how the (city) ecology and water management can look like, and how we can re-welcome the otter to Amsterdam. Which design interventions are necessary in order for the animal to enter the city again? In the first phase of the research, Karelse started a conversation with city ecologists and otter experts. From there, he explored in what ways we can prepare for the arrival of the otter. In order for the otter to thrive in Otterdam, we need to include specific water plants and insects and propose infrastructural changes, like corridors and buffers.

The floating allotment is partly inspired by the floating gardens of Asian and South American cultures, like the Chinampa’s from the Aztecs. If the otter can thrive in these floating gardens, that indicates that the whole biome is also flourishing: the fish, the water plants, frogs, and other beings who are ecologically connected to the otter. In some cities in the Netherlands, some animals are seen as ‘guides’ to indicate the development of a nature-inclusive city. Take, for example, Almere where the otter is treated as an indication of healthy water connections in the city.

The otter is knocking on the doors of Amsterdam, which faces us with the challenge of looking at the water biotopes of our city differently. Water plants are placed on the island to induce the ecology. The garden exists of small islands of plants which induce the ecology of the Waternatuurtuin in Westerpark. On the waterside new plants will grow and visitors are encouraged to take care of them or to give them a new home as well.
