Supporting sustainable coastal development in Jakarta Bay
Jakarta Bay is a heavily utilised area for shipping, industry, fisheries and recreation. The coastline of the Bay is approximately 72 kilometres long and covers 13 cities in the Jakarta Metropolitan Area, giving home to approximately 28 million inhabitants, many of which rely on the Bay for their livelihood. Rapid recent economic development has heavily impacted the Bay and led to a number of land-use conflicts as well as environmental deterioration. Numerous coastal developments proposed or currently underway in the Bay add to the problem.
Therefore, the Indonesian Ministry of Environment (KLH) decided upon creating a policy for the future port and coastal development in Jakarta Bay to ensure its sustainability. Part of this process was the preparation of a Rapid Environmental Assessment (REA) for the Bay, which will provide critical input to the policy document and can be used as a scoping paper for a full Strategic Environmental Assessment (SEA) of the area.
On behalf of KLH, Danida – the Danish International Development Agency – engaged DHI to prepare the REA. To begin with, DHI determined the existing baseline conditions through site visits and available secondary data. Extensive consultations and focus groups served to identify key strategic issues for the Bay. Screening of these issues then helped to prioritise the key physical, chemical, biological and economic impact vectors for assessment in the REA. Finally, preliminary coastal and marine models of the Bay were used to identify critical environmental issues.
The REA highlights that the absence of a SEA and optimised development strategy has resulted in the following main areas of concern:
In addition to assessing these issues, the REA provided an assessment of the specific impacts associated with each proposed project. Generic terms of reference were also provided for:
Based on DHI’s assessment, the client was able to see which developments were in conflict, and what environmental issues needed to be addressed. The document provides critical input to the development of a policy for sustainable development in the Bay.
Making a difference for the people and the environment
Before commencing the REA project, KLH had halted all coastal developments in Jakarta Bay until the cumulative effects could be assessed and addressed. This included the delay of a number of major reclamation projects, including the much needed expansion of the Port of Tanjung Priok, Indonesia’s main port. Completion of the REA allowed some of these projects to proceed, and provided a clear indication of the issues that others needed to address before KLH would allow them to proceed. Significant land-use conflicts and short as well as long-term impacts on the Bay could thereby be avoided, and will be avoided in the future thanks to DHI’s clear listing of the issues and concerns.
Through its REA, DHI set new standards for the management of development projects in Jakarta Bay. For the first time, clear, practical and concrete recommendations were provided on how to fix the problems and allow the majority of the proposed reclamations to proceed without causing conflicts or further negative impacts to the environment. The project has also led to additional SEAs in the region as well as significant interest from several developers in Indonesia. Thereby, DHI is improving environmental outcomes of coastal developments and building the capacity of local environmental regulators to properly manage the environment. Ultimately, this will improve the environmental condition of the Bay while at the same time improving the quality of life of the bay’s residents and allowing for key developments to continue.
