Celebrate life with Cradle to Cradle Islands

Rechten: Alle rechten voorbehouden

Samenvatting

As a part of the European "Cradle to Cradle Island' program, a marina with artificial islands and floating houses will be constructed at the area of Middelplaathaven in Lake Grevelingen, The Netherlands. The "Sustainable Marina of the Future' (Figure 1) will be a showroom for sustainable developing and thinking, innovation, and celebrating life. This part of the project shows concepts for increasing biological diversity at the aquatic-, shore line- and terrestrial area. All designs are based on the "Cradle to Cradle' principle, following the idea of being eco-effective. Ecoeffectiveness incorporates social and economic benefits, while supporting the environment of every life form. Visitors and vacationists become part of the environment, enjoying biodiversity and life while spending time on land and water.

Actually, in addition to climate change is the loss of biodiversity one of the biggest global concerns. It is important to realize that the requirements and needs of the global society derive from nature's diversity. Therefore, the limiting factors of a species, their distribution and abundance need to be understand. What determines a favorable habitat of a population, and how can an unfavorable habitat turned into a good one to guarantee stabilization?

In the last years, water quality and ecological conditions at Lake Grevelingen degraded. The lake has to deal with high retention times, stratification, and anaerobic conditions. These problems were taken into consideration for all designs.

After construction of the "Sustainable Marina of the Future', mobile organisms are able to resettle, experiencing their new environment. But, it is most likely that stagnant water will develop at the inner aquatic area of the islands which makes
resettling and accumulation more difficult.

All designs focus on the support and development of new sustainable environments that have human and ecological values. The establishment of gradients plays a significant role, going from saline to freshwater and wet to dry areas. Each design is provided with materials following the Cradle to Cradle product cycles. Freshwater lenses will develop under the islands through natural and directed rainwater catchment. They offer the possibility to supply residents with freshwater over the whole year. House, garden, and street designs can be experienced on the terrestrial
area. Wetland-ponds create a freshwater environment. The rocky shore and the sandy shore offer a habitat for terrestrial and saline aquatic organisms while bathers can enjoy beach life. Sustainable designs for the marina, including moorages, mooring
posts and sheet pile walls are not influencing water quality and offer an extra environment. An innovation for aquaculture is the design of a floating garden for the cultivation of halophytes. The garden will create an aquatic habitat surrounded by an artificial reef for benthos. Other parts of the aquatic area function additionally as small artificial reefs using different sizes of boulders or reef balls.

All designs support the development of biological diversity. Materials do not contain any toxics, are biodegradable or recyclable. Construction activities and shading of the water column are the only negative impacts. The problem of low water dynamics can be solved.

The "Sustainable Marina of the Future' celebrates life. Designs offer an environment for recreation, conserving and increasing the diversity of species, inspire in the field of sustainable thinking and development.
