<Technology Needs for Lake Management in Indonesia-
Investigation of Rawa Danau and Rawa Pening>


picture 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.
