Mapping geological potential
The administrative restrictions for exploitation of
mineral resources are based on master spatial
plans of the County and as well as conditions of
land use, water supply protection, soil and cultural
well.
The results of theb integration a map of geological
potential and spatial restrictions is a map of
restricted geological potential of mineral
resources.
The final map of a restricted geological potential
display a certain raw materials, including
administrative restrictions in context of mineral
exploitation (central and local government
agencies):
•road infrastruture
• protected area ( nature park)
• distance from settlements ( ½ km – 200 m)
• nature reserve
• tourist resorts
• valunable land
• water resources protection
• protected landscapes
• archeology zones
• marine protected area (1km to the land; 300m to
the sea-ZOP)

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

Management of mineral resources – effects of exploitation
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.
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
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 Management
http://www.sarmaproject.eu/
Project summary
Aggregates (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.
