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

C. Methods of Investigation

Some consideration was given to the best method by which to proceed in investigation of the technological needs for management of the two lakes. Clearly, it was not possible to define the requirements from the available literature without a great many assumptions.

The following general procedures were adopted.

1 Collection of literature

All available literature and data on the two lakes were to be collected, usually by photocopies, compared, and evaluated.

2 On-site visual investigations

Both lakes were to be inspected to determine whether there were any apparent discrepancies between the reports and the observed state of the lakes at present.

3 Discussions

Discussions would be held with staff of all interested Government Departments, instrumentalities and organisations. These would be used to enable definition of any perceived problems, ecological issues, or conflicts of interest over the lakes. An attempt would be made to extrapolate such issues from the present to the future.

4 Management options

A full range of management options for the lakes would be formulated. These would be based on the existing data and information unless that could be shown to be unsound, inappropriate or inaccurate. The management options would be based on ecological sustainability, as well as optimisation of resource use.

5 Ranking management options

The options for management would then be ranked with reasons. It is recognised that this involves a high degree of value judgement. As far as possible, the values would be stated.

6 Relevant technologies for preferred options

Relevant soft and hard technologies which might be employed in management of the lakes would then be listed and their relevance explained.

7 Assessment and evaluation of results

The results of the investigation would be assessed to determine whether there were any general conclusions which could be drawn. In retrospect, it proved to be impossible to determine which Government Departments were involved to a greater or lesser extent with the management of the lakes. Probably most Departments would be able to claim involvement in some way. Equally, it proved to be impossible within the constraints of time and finance to speak to a wide spectrum of the local populations. Because of the organisational arrangements and the distances involved in travel to the lakes, it was not possible to have discussions with staff of many Departments after investigators had reached definite conclusions about the lakes. Meetings were arranged immediately after the visits to the lakes and prior to any assessment of findings. Ideally, one would have preferred to have been able to have two meetings with Government staff dealing with each lake. The first meeting should be after the first inspection of the lake and should be aimed to obtain information from Government officials. The second meeting should be later and should provide information to Government officials about the findings of the investigation.
