yellowing and finally harvesting. Figure 2 gives an outline of the proposed system. An initial data base of potential rice producing units has to be assembled. The irrigation unit, with its uniform irrigation and vegetation timescale, could be used as a base unit. This database will be filled by data from satellite imagery, aerial photography and fieldwork. The accuracy of this database is therefore not exclusively depending on the geometrical accuracy and resolution of satellite imagery. The operational system will then use the satellite data to identify whether the fields are actually irrigated and wether rice is growing and being harvested. 4.3 Assessment of yield and detection of pests and diseases Apart from the identification of rice fields, remote sensing can also be used to detect the ratio between the high yielding varieties and the convential varie ties. Possibly a further detailed subdivision in these varieties could be made, but this has to be studied. In areas where crop diseases or pests are occurring, crop development monitoring can be used to determine the spread of the disease. To make disease and pest monitoring possible, the effect of the disease should be such that crop colour and associated structure have changed to such a degree, that the image interpreter can conclude that the cause of the change in crop appearance and associated patterns, should be attributed to the outbreak of a disease or pest. This information could be used to improve the efficiency of field surveys and of the measures to bring the diseases and pests under control. It is expected that the high repetition of obser vation in combination with the high spatial resolution and the spectral band selection optimized for vegetation monitoring, can provide an excellent tool for crop disease and pest control. The information on the extent of pests and diseases, in combination with the information on the distribution of the different rice varieties, can improve the yield forecasts and estimates. The related benefits are the reduction of production losses and the improved efficiency of pest control by a reduced usage of pesticides. On the basis of remote sensing data an early warning system could be established in order to minimize economic losses due to pests and diseases. 5 UTILISATION PREPARATION PLAN Remote sensing as a source of information is already used by a number of organizations in Indonesia (e.g. Public Works, Transmigration, Forestry, Environment, Central Bureau of Statistics, Bakosurtanal). The projects of these organisations will benefit from the direct reception of Landsat images by the LAPAN groundstation, which will be operational in the near future. In the past these images arrived with long delays (and often too late) from foreign stations. By upgrading the station in the future, it will be possible to receive also the high resolution images from Landsat 5 and Spot and lateron possibly TERS. A requirement exists for an overall approach to the application of remote sensing techniques in Indonesia. Part of this should be an inventory of the present practical applications of remote sensing in Indonesia. In a large number of projects remote sensing methods are already used as an important source of information, especially in those cases where other sources of data, like topographic maps are outdated. In a stepwise development of remote sensing all the different available sources of data should be used in an integrative approach. Important steps are designated by the present Landsat station, for the reception of MSS data, becoming fully operational and the updating of this station to X-band for the acquisition of high resolution data like Landsat Thematic Mapper (TM) and Spot. On the one hand this station will supply data for applications (and research) and on the other hand it will produce on the job training in the handling of large datastreams as will be provided by most future satellites. Although no requirement exists for a centralized remote sensing institute, a coordinated national effort is required to develop the remote sensing techniques into operational tools for the Indonesian development programs. The platform for such a national program for the development of remote sensing is already available in the different organisations involved in the research and development as well as in the practical use of remote sensing. 6 CONCLUSIONS Preliminary analysis of potential benefits of a satellite remote sensing system with the capability to monitor crops and forests indicates that multi million dollar benefits may be expected. Such a system is not yet in existence, but from imagery of present satellites the feasibility of realising these benefits can be demonstrated. Further studies are pursued in order to substantiate these findings and to arrive at conclusions, if and when such a multi million dollar investment for a dedicated equatorial earth observation system for the monitoring of renewable resources is justified.
