Groundwater Utilization Must Observe Environmental Balance
MINISTRY OF ENERGY AND MINERAL RESOURCES REPUBLIC OF INDONESIA
PRESS RELEASE
NUMBER: 683.Pers/04/SJI/2019
Date: 28 November 2019
Groundwater Utilization Must Observe Environmental Balance
Groundwater
is a renewable resource, but if we don't manage it properly by observing the
balance between its absorption and extraction, it will be depleted.
"Groundwater plays an important role in a
variety of purposes, thus its utilization must observe the balance and the
conservation of resources, something we call 'environmentally friendly'," said
Advisor to Minister of EMR for Economy and Natural Resources, Sampe L. Purba, in
his remarks at the Groundwater Talk Show titled "Well-Conserved Groundwater,
Well-Off Farmers " in Surabaya, Thursday (28/11).
Through this talk show, Center for Groundwater
and Environmental Geology, Geological Agency, Ministry of EMR, wants to disseminate
the policy on groundwater utilization for farming and to find the solutions to deal
with the issue of groundwater utilization for irrigation in East Java Province.
On the same occasion, Head of EMR Service Office
of East Java Province, Setiajit, raise the subject of decreasing volume of
surface groundwater. "For example, several water springs in Malang were
initially quite large, but the volume is now decreasing. This means we have to
conserve the environment, we also have to guard our forests," he said.
The water resource, including groundwater, is
used for various human activities, such as daily household need, industrial
activities, farming, fishery, and the service sector support.
In farming, the majority of water used is from rain
water, river/reservoir water, and groundwater obtained by making bore wells.
Demand for groundwater is currently huge, for
basic needs, households, industries, and farming. In the past, surface water
was quite abundant and in good quality; rivers even flew steadily throughout
the year.
Presently, most Indonesian farmers water their
fields by using irrigation water from surface/reservoir water.
In a number of Indonesia areas where surface
water is lacking, farmers use water from bore wells.
The over-extraction of groundwater more than its
replenishment will lead to groundwater decreases. In Madiun--in particular in Balerejo
area--the level of groundwater decreases by 20 m within a 12 year period (between
2007 and 2019).
Meanwhile in Sragen Regency--within a three year
observation period (2016-2019)--the groundwater does not decrease although many
farmers use groundwater.
Besides the huge consumption of groundwater, the
resources of groundwater has also been degraded. Water comes down from the sky directly
into the ground. Now, only little water is absorbed by the soil, and thus, only
limited volume of it becomes great surface water.
This indicates that the water potential in each
area is different, so the policy on groundwater utilization for irrigation must
be regulated according to the groundwater potential. This way, groundwater will
be conserved for the current and future generations. (IY)
