    Mitigation of environmental impacts in ornamental rock and limestone aggregate quarries in arid and semi-arid areas by M.A. Peñaranda Barba, V. Alarcón Martínez, I. Gómez Lucas, J. Navarro Pedreño

    Published 2021-10-01
    “…In the Region of Murcia, in Spain, as well as other Mediterranean areas with similar climatic conditions, there is a great deal of mining activity linked to the building sector, in which mainly ornamental rock (marble and marble limestone) and limestone aggregates are used. All of this has given rise to numerous active and abandoned mines, where no restoration process has been carried out, generating strong impacts on the environment.METHODS: In this study, 8 environmental impact assessments studies of ornamental rock and aggregate quarries in the Region of Murcia were analysed to identify the negative impacts on the abiotic and biotic environment, landscape, socio-economic and socio-cultural environment, and infrastructures and analysing preventive and control measures. …”
