Innovation applied to the recovery of degraded areas by clay extraction through the installation of fish culture activity in the region of the sub basin of the upper region of the Machado River, Rondônia, Brazil

The ceramics industry is one of
the main impacting activities regarding the
conservation and watershed management
with the extraction of clay, the raw material
for manufactured goods such as tiles,
bricks, hollow elements among others.
The Pimenta Bueno region located in the
southern cone of Rondônia state is characterized
by a geology named intercalated
shale of the Cacoal Formation, displaying
layered deposits related to this activity. The
existing environmental liabilities, although
being the responsibility of mining companies,
causes conflicts with environmental
managers, generating pressures from society
to restore and establish the compatibility
of the mineral extraction activity and
the environment. Generally, pits originated
from clay extraction are abandoned and
end up being flooded by rainwater or
groundwater, result in small ponds with
depths ranging from 1.5 to 5.0 meters.
The objective of this study is to determine
the feasibility of fish culture as an
alternative activity for the recovery of the
degraded areas in intensive system, as
well as an alternative for income generation,
food safety, in addition to the reuse
of areas previously left as environmental
liabilities. It was used as method the descriptive
research with periodic observation
visits, interviews with questionnaires
prepared with managers and officials of
the studied ceramics industry. As a result
it was observed that the fish culture consists
of an alternative that allows areas to
mitigate environmental liabilities generated
by the extraction of clay. And yet, it
offers a competitive advantage for companies
in this sector since it becomes a
profitable alternative.
