Connectivity

26 April, 2011

Scientists are seeing the first effects of climate change primarily in natural phenomena. Migratory birds are returning earlier or they do not migrate at all. Butterflies are being seen in completely new habitats. Plants are growing at higher altitudes. Biologists investigating these phenomena conclude that many species will die out simply because there is a limit to their ability to adapt. A bird may return from its migration early, but if the caterpillar which is its main food source does not appear as expected, then the bird will not survive. And mountains are only so tall: plants cannot grow beyond the summit! Scientists are impressing upon policymakers the need for large, interlinked nature reserves. This will give plants and animals space to migrate to new, suitable habitats.

'Connectivity' is a hot topic in Australia, as it is in many other countries. Several initiatives have been put forward to create natural corridors between current nature preserves crossing through agricultural areas and towns and cities. By developing clever projects with the close involvement of private parties and local communities, natural corridors stretching for thousands of kilometers can be created, such as the 'great eastern ranges corridor' that stretches along the entire eastern Australian coast. Despite the call for greater connectivity, the current cabinet in the Netherlands is phasing out the 'ecological main structure', mainly to save money and because of opposition from the agricultural sector. The 'great eastern ranges project' does not have many financial resources. Rather, a local, project-based approach is used that offers small financial incentives to emphasize the ecological and economic benefits and to encourage landowners to get on board. The way in which the Netherlands' policy on ecology is currently being communicated and implemented pales into insignificance when one compares it with the enthusiasm and passion displayed by Australian politicians who are active in this policy area at the state and local levels.
