abstract: 'Mining and quarrying provide the basic raw materials for sustaining
|
|
|
|
human well-being and are critical for achieving economic developments.
|
|
|
|
At the same time, environmental degradation and its associated social
|
|
|
|
impacts and inequalities have become a grave reality of mining sector
|
|
|
|
that affects all nations, individually and/or collectively. Assessment
|
|
|
|
of the environmental impacts arising from mining and quarrying is
|
|
|
|
critical to limit the environmental problems within the barest minimum
|
|
|
|
levels. Although many impact assessment studies are available on
|
|
|
|
mining/quarrying of different major and minor minerals, not many studies
|
|
|
|
exist on quarrying for laterite blocks which is being widespread in many
|
|
|
|
of the fast developing tropical and sub-tropical regions of the world
|
|
|
|
like India. Therefore, this paper evaluates the impact of laterite
|
|
|
|
quarrying for construction blocks, in one of the twin river basins in SW
|
|
|
|
India, the Netravati-Gurpur river basin, where the activity is
|
|
|
|
widespread. The Rapid Impact Assessment Matrix (RIAM) method was used to
|
|
|
|
evaluate the impacts of laterite quarrying as it allows a comprehensive
|
|
|
|
analysis of the results based on the individual environmental score
|
|
|
|
obtained for each component. RIAM is a valuable assessment tool, owing
|
|
|
|
to its capability in quick, collective and reliable evaluation of the
|
|
|
|
impacts that can aid decision making and minimization of environmental
|
|
|
|
impacts, especially at early planning stages. Data pertaining to
|
|
|
|
resource extraction, identification of impacting actions, mapping of
|
|
|
|
mining hotspots, etc., were collected from primary and secondary sources
|
|
|
|
through systematic field work and sample collection, questionnaire
|
|
|
|
surveys within the local community and other stakeholders such as mine
|
|
|
|
operators, labourers, officials of Government departments, etc. A total
|
|
|
|
of 21 laterite quarries are located in the basin with a total production
|
|
|
|
of 5.7 million laterite bricks/year (0.115 x 10(6) ty(-1)). The impact
|
|
|
|
assessment study revealed that the activity not only disturbs the
|
|
|
|
natural environment especially, hydrology, air quality and noise levels,
|
|
|
|
ecology, land use and soil stability but has profound influence on the
|
|
|
|
socio-economic factors of human health and immunity, displacement, etc.,
|
|
|
|
of the quarrying-hit areas. The activity also recorded both long-term
|
|
|
|
and short-term positive impacts as a source of employment and income
|
|
|
|
generation. Additionally, the activity favours groundwater replenishment
|
|
|
|
and agriculture productivity of the area where appropriate mine closure
|
|
|
|
measures were taken up. However, the positive impacts of the activity
|
|
|
|
are far outweighed by the fact that most impacts of laterite quarrying
|
|
|
|
are of class - C (moderate negative impact) and - D (significant
|
|
|
|
negative impact) owing to the long-term socio-environmental and
|
|
|
|
bio-ecological implications of the activity. Thus, it is imperative that
|
|
|
|
there is significant improvement in policy and regulatory framework and
|
|
|
|
its implementation for mining and quarrying of building materials which
|
|
|
|
is vital for meeting future development requirements.'
