Few
people would dream of the Ciliwung River corridor becoming a place of leisure
like Central Park in New York City. What if you knew that some 150 years ago,
Central Park was built on top of the old slums of Upper Manhattan, conceived
then principally to store and manage the water resources of Manhattan.
If
so, is it inconceivable that together, Jakarta and West Java could create its
very own “Central Park” by transforming the flood-prone Ciliwung River into a
water resource and open park for the city?
What
is needed to make this a reality is a strong vision to transform the river to
the first public green corridor of cities and regions in its watershed.
Indeed,
the Ciliwung that runs through the cities of Bogor, Depok and Jakarta, offers
a unique possibility of creating a liveable river corridor. With
approximately 5 million people residing within the Ciliwung River’s
384-square-kilometer catchment, the benefits and urgency of making this
vision a reality should not be understated.
The
Ciliwung is however heavily polluted as a result of industrial and
agricultural waste discharge occurring primarily in the middle stream.
Untreated
domestic waste also dumped into the river and untreated urban runoff from
Bogor, Depok and Jakarta worsen the problem.
Not
surprisingly, the river is in no way a raw water source for Jakarta, which
has, instead, been relying on groundwater as its main source. Studies,
however, showed that the shallow groundwater system in Jakarta is highly
polluted with contaminants.
The
city needs a better source of water and a better environment, it is,
therefore, worthwhile to invest in a long term vision for Ciliwung.
Can
we change the identity of the entire Ciliwung River Valley in Jakarta and
West Java into an exemplary and productive landscape, where the improved
quality of life adds value to the society within a healthier and economically
sustainable environment for Jakarta?
Transforming
the highly degraded Ciliwung into an exemplary landscape that promotes the
sustainable and equitable use of water for the regions requires not only time
and resources, but more importantly, continued political support and
expertise through strategic partnerships with civil society, research
institutions and industry.
The
Ciliwung offers a unique possibility of creating a liveable river corridor.
Five
years ago, the Future Cities Laboratory based in Singapore initiated a
collaborative research project on the Ciliwung, bringing together ETH Zurich
— the Swiss Federal Institute of Technology in Zurich — and Indonesian
institutions including the University of Indonesia (UI), Bandung Institute of
Technology (ITB) and Bogor Agricultural University (IPB).
With
local involvement, the project aimed to develop solutions to address
flooding, water quality, and ecology that meet the needs of the local
population, while responding to pressures of a growing megacity.
More
importantly, the team offers “river rehabilitation” as a holistic and
sustainable alternative to “normalization”. Indeed, the river cannot be
understood in isolation.
A
multidisciplinary approach is necessary to study a complex system such as a
119-kilometer river with 5 million people residing within its catchment.
Moreover,
a multi-scale framework puts the spotlight not just on settlements inhabited
by the local community, but also the river corridor and the entire river
catchment.
Focusing
on the natural and engineered environment, the integrated framework links
urban fabric and river dynamics, prioritizing ecosystem services, integrating
the river and the people, and finally developing river corridor
rehabilitation scenarios.
The
guiding principles of river rehabilitation are to restore the ecosystem
services that the catchment and the river are capable of.
While
“ecosystem service” is widely understood among scholars, it may not mean
anything to the community along the riverbank.
The
survey results showed that the economic benefits of a more ecological
approach to the rehabilitation of the Ciliwung extends beyond the areas along
the river corridor.
During
fieldwork along the river, researchers found that integrating local knowledge
into the river rehabilitation plan goes a long way in creating a more
sustainable and ecologically sound design.
The
outcome was a proposal for the site level, enhanced with local knowledge,
that covers a wider range of social and ecological goals beyond flood
protection and mitigation.
At
the scale of the river corridor, catchment management and localized site
interventions can be integrated as a holistic proposal for the river system.
At
this scale, the merits of this integrated approach, compared to the
“normalization” approach, become even more apparent.
The
Ciliwung River Project is driven by the vision that combined efforts of
research institutions, hydrologists and hydraulic engineers, landscape
architects, urban planners and developers can improve the landscape and water
quality of the urban river while mitigating flood risk.
More
importantly, stakeholders must be strongly committed to implementing these
innovative solutions. Recognizing the Ciliwung River as a public space and
natural corridor presents an important opportunity for the region, and could
well be the “tipping point” in taking the plunge towards a long term
commitment for environmental improvement.
Many
Asian cities, such as Seoul and Singapore, have improved their urban river
landscapes considerably in recent decades.
This
has boosted their global image and enabled them to reap economic benefits
that far surpass the investment in river rehabilitation. The Ciliwung River
park could become the bearer of such a strong landscape vision for Jakarta.
Research
by the Future Cities Laboratory shows that beyond solving immediate
engineering challenges and improving risk management, the Ciliwung River
Project is as much about the reinvention of the river as a brand for Jakarta
and West Java — a brand capable of projecting a strong and positive environmental
image with sustainable goals.
The
rehabilitation of the Ciliwung would not only contribute to Greater Jakarta’s
nature-friendly image, but would invite the population of West Java and
Jakarta to reconsider an appreciation of their other rivers as a dignified
part of their urban landscape.
If
becoming the Central Park of the East seems far-fetched for the Ciliwung at
this stage, taking the first step towards river rehabilitation could put
Jakarta in the league of other major Asian cities that dared to engage for
the change.
But
first, someone needs to take the first political step towards a long term
commitment, to take the first plunge towards a better environment for all. ●
