AT-7 :: Restoration and re-cultivation of land

As soil and land are finite resources, the restoration or re-cultivation of unused or polluted areas is essential. Open questions regard benefits of re-cultivation, soil quality, liability of pollution and assessment of the pollution source and extent. Abandoned land should be re-purposed to be able to fulfil other necessary functions.
• How can sealed areas be re-cultivated to fulfil soil functions and improve land sparing elsewhere?
Natural Capital
• How can re-cultivation of soil be achieved in a way to save the most resources? (challenge: to achieve this for large construction sites as well as for small gardens; assess the added value for spatial planning)
• Develop a guideline to assess the soil quality on large construction sites in view of resilience.
• Assessment of pollutants (e.g. long-term impact of heavy metals or pesticides in soil; pollution load of high current masts, wood impregnation)
Land management
• What are the possibilities for re-cultivation of abandoned land and what are the benefits for sustainable land management?
Net impacts
• How can funds or incentives for re-cultivation support sustainable land use?
• Is it beneficial and implementable to let revitalisation costs be paid by the polluter or the user?
