At County of Dubrovnik-Neretva area of geological potential for dimensional stone aggregate amount 562 km², but implementing MPA-a, 239 km² or 43% geological potential zone , cannot be used for investigestion and exploitation. According to authors of strategy of managment of mineral resources of Republic of Croatia (Krasić et al.,2008), restriction gave to mining activities implementation of MPA-a are results inherited weaknesses in the field of activity as well as unknown opurtunities designed and used of enviroment.

ARHITEKTONSKO-GRAĐEVNI KAMEN

With strategy of managment of mineral resources of Republic of Croatia within MPA-a recommend admission of mining activities of mineral resources in function of recovery and useful design abundand mining objects. Consenquently proposal which changes will be requested, extraordinary status of same areas for exploatation dimensional stone aggregate within MPA-a, like in case of island Brač. We need initiative from local self-goverment, county department, county economic council, professional group owner of quarries, Croatia economic council county Dubrovnik, Ministry of economy, Labour and Entrepreneurship, Department of mining.

Management of mineral resources – effects of exploitation Management of mineral resources – effects of exploitation

Certainly, therefore emphasis should put on rarely amount dimensional stone quarries, like economic possibilities, and tradition construction with stone like part of cultural identity all region, and little influence on enviroment exploatation of dimensional stone aggregate. How strategy needs to serve like expert basic for established policy of managment of mineral resources, local self-goverment is the one of the most significant subject in entire system. The main problems connected with exploatation of mineral resources are:

•destruction of public local road infrastucture•loudness•dust•negative enviromental influence•non-recovery pits

Management of mineral resources Management of mineral resources Ministry of Economy, Labour and

Entrepreneurship, still from 2001.suggets increassing fee for exploitation from 2,6 % at variac amount toward type of mineral resources, wherefore 50% goes to local self-goverment, and 50% goes to state budget of Republic of Croatia, so debate is possible just after proposal new Mining law. For abunded pits and sites is need to create a posibility for natural recovery, and priority list of abunded pits. The spacing of present investigestion area and exploitation fields of mineral resources is results of intesive construction in county.

However,certain number of present fields are in area which are defined like unfavourbly for exploitation in spatial plans of county. Inclusive, all locations of mineral resources need to locate in new law order. In that effect the authors of strategy of management of mineral resources of Republic of Croatia suggest that under basis of geological study, study of effects on mining activities at enviroment, as well as spatial-plans criteria to provide the locations for investigestion and exploitation of mineral resources is needed to establish the zone of exploitation.

SARMa - Sustainable Aggregates Resource Managementhttp://www.sarmaproject.eu/

Project summaryAggregates (crushed stone, sand and gravel) are crucial for infrastructure and construction. SEE countries are rich in aggregates, but supply is not coordinated within or across the area. Challenges are illegal and damaging quarries, unreclaimed sites, limited recycling and community opposition. Fulfilling demand requires efficient and sustainable supply chain (planning, extraction, transport, use and recycling), and socio-eco friendly quarrying, to preclude opposition to extraction, supply bottlenecks, and restricted growth. Main objectives of the project are to develop common approach to sustainable aggregate resource management (SARM) and sustainable supply mix (SSM) planning, at three scales, to ensure efficient and secure supply in SEE. Specific objectives include capacity building, information infrastructure creation, and planning for a Regional Centre on SARM and SSM. Local, site-level activities will focus on environmentally friendly extraction through best practices, reducing illegal quarrying, and recycling to reducing use of primary aggregates. Region/national activities will create a SARM framework for effective management, and define SSM, as well as recommend how to integrate SSM into planning and legislation. Transnational activities focus on harmonization of relevant policies and legislation across SEE, information transfer, and creation of an Aggregates Intelligence System. The project builds the foundation for a Regional Centre on sustainable aggregates management and supply. Main outputs will include capacity building materials: printed materials (manuals) on (1) local level aggregate operation improvements, (2) regional, national and transnational policy, legislation, management and supply mix, (3) C & D waste management, tools, methods (e.g. life cycle analysis); and regional, national and transnational events. Results will include use of best practices, adoption of SARM and SSM, harmonized policies, and ongoing collaboration among partners.
