Quarrying and impacts on the environment:

……. One of the most important environmental problems is thedereliction of abandoned pits or quarries. The reclamation of mined-out

land contributes to the reduction of environmental impacts of aggregate

extraction (Šolar et al, 2009).

Quarrying and impacts on communities:

…….. Although the aggregate industry has a positive regionalimportance as a source of employment and the benefits of aggregate

utilization are dispersed over very large areas, it is common for thecommunity where extraction occurs, to suffer most of the adverse

consequences of resource development. Clearly a balance is needed

and a balance should be sought (Langer, 2009).

Quarrying and Sustainable Development



SNAP-SEE

• Concerns over resource scarcity and limits to economic

development posed by the capacities of natural

environments go back about 200 years (Morgan, 2008)• Since Earth has finite resources (arable land, energy,

mineral resources and pollution carrying capacity), the

depletion of non-renewable resources such as minerals,

there must be limits to exponential economic growth,

population and pollution• These and similar concerns led to the “Sustainable

Development” concept




SNAP-SEE

• Sustainable Development:

"development that meets the needs of the present without compromising the ability of future generations to meet their own needs" (Commission on

Environment and Development, 1987)

This statement incorporates:1. The concept of needs, in particular the essential needs of the world's poor

2. The idea of limitations imposed by the state of technology and social

organization on the environment's ability to meet present and future needs

Sustainable development:1. environmental sustainability

2. economic sustainability

3. Socio-political sustainability




SNAP-SEE

It is a culture that addresses terms how mining and quarrying

can contribute to sustainable development

It is a concept of needs, an idea of limitations, a future orientedparadigm, and a process of change

The goal of sustainability with respect to minerals is to maintain

the stream of benefits that minerals provide in such a manner

that the net contribution of the resource is positive over the life

cycle of a mine or quarry, and product




SNAP-SEE

In order to achieve sustainable development, as far as

quarrying is concerned, certain changes need to take place:

• in the way exploitation is perceived,• in the exploitation itself

This includes both institutional changes by the authorities as

well as application of novel exploitation techniques by theoperator , which should be consistent with the future as well

as the present needs

Best Practices

Terms:

1. A method or technique that has consistently shown results superior to

those achieved with other means, and that is used as a benchmark

(http://www.businessdictionary.com/definition/best-practice.html)

2. A technique or methodology that, through experience and research,

has proven to reliably lead to a desired result . A commitment to usingthe best practices in any field is a commitment to using all the knowledge

and technology at one's disposal to ensure success (http://searchsoftwarequality.techtarget.com/definition/best-practice)

3. A set of guidelines, ethics or ideas that represent the most efficient or

prudent course of action. Best practices are often set forth by an

authority, such as a governing body or management, depending on the

circumstances. While best practices generally dictate the recommended

course of action, some situations require that such practices be followed.

• The development of best practices in quarrying is highly

related to the principles of sustainable development

• Certain practices should be followed in order to:1. preserve natural resources

2. avoid reverse impacts on society

3. provide aggregates to the market, and

4. contribute to economic growth

• “Best practices” are all the activities, actions, practices

that may be the means and conditions for the attainment

of sustainable development in quarrying

Best Practices incorporated in Laws and Regulations

and Codes of Practice



SNAP-SEE



• Best practices can be viewed as a bridge between quarrying and Sustainable

Development.

• In this sense, best practices have served as a tool to manage sustainability.

Examples

1. The Department of Primary Industries in Victoria, Australia, published in 2010 a

code of practice for small quarries: It is stated that the purpose of the code is

for operations to implement best practices

2. The Department of Primary Industries, Water and Environment and the

Department of Infrastructure, Energy and Resources in Tasmania, Australia

has published in 1999 a code of practice for quarries: “Best methods” of achieving results are mentioned

3. The Economic Commission of Africa published the ”Compendium on best

practices in small scale mining in Africa”: Best practices for mining are listedand references to quarry operations are given as examples of specific best

practices

These are some of the first steps to incorporate best practices into

official documents by public authorities monitoring / supervising

quarry operations.



SNAP-SEE

Indicative list of Best Practices in Quarrying

Definite guidelines for the application of best practices do not exist,

so each quarry may apply different procedures that can be termed “BestPractices” or “Sustainable Environmental Management”

A number of technical and non-technical issues that contribute to sustainable

environmental management may be used as the foundation for a code of “bestpractices”

Air Pollution Quarry Fines and Waste

Blasting Restoration and Rehabilitation

Ecology and Biodiversity Social Issues and Community

Nature Conservation Transport and Traffic

Noise Visual Issues and Landscape



SNAP-SEE

Indicative list of Best Practices in Quarrying

Grouping issues within each pillar of sustainability (environment, society,

economy) shows that all issues interact with all pillars

All issues may be related

to all pillars.Interaction between

separate issues is also

expected



SNAP-SEE

Doing our best

The concept of a “best practice” has evolved through the years, in aeffort to document successful procedures and processes undertaken

by operators and/or authorities and/or regulatory agencies to achieve

a “good result” with respect to Sustainable Development

It is well known that no two operations are the same and conditions

usually vary from quarry to quarry and from mine to mine

Hence the “best” concept has evolved where methods and procedures

are given more in the form of “develop your own control plan based onstate-of- the art technologies and adhere to it” than in the form of

absolute numbers and formulas



SNAP-SEE

Doing our best

Environmentally, for a mine to contribute to sustainable development, it

must abandon ad hoc approaches to environmental management, and

adopt a more proactive, preventative stance

A mine should develop its own environmental control and socialacceptance plan based on conditions termed important for the specific

operation and then successfully apply this plan

Successful plans, therefore, require a commitment towards continuous

environmental and socio-economic improvement, from mineralexploration, through operation, to closure



SNAP-SEE

Summary and Conclusions

• Best practices in quarrying should be viewed as procedures and processes

adopted by a quarrying operation that may provide a framework for the

development and application of science and technology to enhance the

industry's environmental stewardship

• In this respect, operators and authorities should develop control plans thatwill cover all issues pertinent to the specific operation to ensure

sustainability

• Quarrying by itself will never be a sustainable operation, since non-

renewable resources are depleted

• However, if quarrying is performed by adhering to sustainable development

principles and thus by applying best practices as identified for the specific

operation, then quarrying can be viewed as provided the needed materials

for development in a sustainable manner
