The reclamation of hardstone quarries in the Maltese archipelago

Abstract

Quarrying has been a feature on the Maltese landscape for approximately 6000 years. In the past two decades increased quarrying practices, particularly in the hardstone sector, have been threatening the existence of our diminishing countryside. This priceless resource, so important for both leisure activity and in promoting the islands in the sphere of international tourism, is being progressively degraded. This dissertation examines the reclamation potential for quarries in terms of agriculture, fish-farming, land filling, built development, water storage, forestry and general amenity. There is no hard-and-fast rule as to the suitability of one form of afteruse over another. It all depends on the location, size and intended afteruse for any one particular site. One promising solution would entail the use of specialised blasting techniques which are giving optimal results elsewhere. This study also focuses on the reclamation potential of a number of disused hardstone quarries located in the Maghlaq area, part of which is expected to be incorporated into an archeological heritage park. Given the unique natural setting of the area, a nature conservation type of reclamation seems to be the most appropriate. However, the active quarry nearest to the proposed park could be utilised to house all the related facilities without further degrading the natural landscape. Specifically, this dissertation lays out the technical, ecological, and geographical considerations necessary for successful quarry reclamation.
