<Technology Needs for Lake Management in Indonesia-
Investigation of Rawa Danau and Rawa Pening>
All over the world, lakes and reservoirs are suffering from degradation due to
the lack of management and appropriate technologies to facilitate their proper
use and preservation. Indonesia is a country in South East Asia with a number of
lakes that are utilized for different purposes, and that require the development
and implementation of sound management plans, including the use of appropriate
technologies. The Government of Indonesia, through the Agency for the Assessment
and Applications of Technology (BPP Teknologi), is making efforts to ensure that
environmentally sound technologies are used in the planning and management of
resources including freshwater bodies. It is in this context that the
International Environmental Technology Centre of UNEP collaborated with BPPT in
implementing the project Technology Needs for Lake Management in Indonesia.
Originally the project considered six major lakes, but, due to technical and
budgetary considerations, the focus had to be given to lakes Rawa Danau and Rawa
Penning, both in the island of Java. The past and present characteristics of
these water bodies, the organizational structure of the Government Agencies
involved in their management, and the difficulty in accessing existing data made
this project quite complicated but challenging. In addition, the majority of the
field work was done in the haze caused by the smoke from the forest fires, with
consequent adverse health effects for one of the members of our research team.
This publication provides a general diagnostic analysis of Rawa Danau and
Rawa Penning. It describes and discusses environmentally sound technologies and
management practices that are appropriate for the preservation of both water
bodies in Indonesia. It is hoped that the project has been beneficial to
Indonesian and that this publication will be helpful to the national agency in
charge of the assessment and application of technology as well as to other
related agencies responsible for the environmental management of Rawa Danau and
Rawa Penning.
The information gathered for this project was collected from a number of
sources, i.e., journals, archives, publications and other library materials and
information materials provided directly by government agencies as well as by
experts. The final revision of the present publication was undertaken by V.
Santiago from UNEP IETC.
