Deciding the optimal after-use direction (e. g. forest, water body, meadow, arable land) after excavation should take into account several restrictive criteria. Those can be derived from legislation (for example need to preserve habitats for endangered species), environmental conditions after land resource extraction (e. g. (ground) water table height), and socio-economical and political criteria (possibilities for real-estate development, acceptance of maintenance costs after recultivation and so on). Do define and organise such criteria we cooperated with various experts from universities, governmental agencies and also practitioners (mining operators). Now we could move on to develop comparison criteria system in cooperation with wider community of stakeholders engaged in after-use of quarries.
