Simulating urban encroachment upon Natura2000 sites using the MOLAND model : supporting appropriate assessment

The urban fabric of the Greater Dublin Area (GDA) has expanded rapidly over the past 20 years. This has lead to a decrease in environmental quality throughout the region and disturbance of protected areas. In an effort to guide development toward a more sustainable path in the region the “Strategic Planning Guidelines for the Greater Dublin Area” were introduced in 1999. These were updated in 2004 as the “Regional Planning Guidelines: Greater Dublin Area 2004-2016” and are currently in the process of another review to become the “Regional Planning Guidelines: Greater Dublin Area 2010-2022”. As part of the review an Appropriate Assessment was undertaken to evaluate the effect of
several potential settlement patterns on the region’s protected areas. The MOLAND model was used to simulate four scenarios of possible future settlement patterns for the GDA. These four scenarios were then evaluated in terms of the impact of development on protected areas within the region.
