451 Symposium on Remote Sensing for Resources Development and Environmental Management / Enschede / August 1986 Explorations of the enhanced FCC 1:100.000 for development planning Land-use identification in the Nairobi area F.Grootenhuis & H.Weeda Nairobi, Kenya K.Kalambo Landplan, Nairobi, Kenya The objective of this study was to explore the information content of the LANDSAT image at 1:100.000 scale regarding the existing land-use. The visual interpretation of the readily available LANDSAT image produced a land-cover map at 1:1M scale of the Nairobi area (Grooten- huis, Weeda & Kalambo 1986a). The zones of the land-cover map were transferred to the print photographically enlarged to scale 1:100.000. Fieldwork was carried out to establish the loca tion and the character of the mapping unit boundaries. Through field checks and background information, different land-use units were identified within the land-use zones. The relative distribution of the units was recorded. The representative cross-sections and block diagrams show the existing interaction between man and his environment. Comprehension of the spatial distribution and use of the existing land resources is essential to integrated planning for development. The land-use map at the scale of 1:100.000 overlain on the LANDSAT image provides an integrated data source which permits the planner to evaluate and assess field data in relation to visible bio-physical patterns. This is of great value in the formulation and implementation of landscape policies. 1 INTRODUCTION Planning for development will have to deal with two major problems: i.e. the need for more space and more production (Thimberlake 1985). The landscape planner's design ex presses a view on the balance between the impact of continuous changing needs and the "carrying capacity of nature" (McHarg 1969). This capacity can be defined as the level to which the environmental conditions allow the exploitation of natural resources (Tolba 1982) The interaction between the environmental factors is reflected in the way land is used at a particular moment. Therefor, a map of the existing situation is an important tool for landscape planning (Duchhart 1986) This paper describes the information that could be drawn from a photographic print of LANDSAT image at the 1:100.000 scale to com pile a land-use map at the same scale. The study has been undertaken as a follow up of the Extended Training Course on Remote Sensing and Rangeland at the Regional Remote Sensing Facility (RRSF) in Nairobi, Kenya (October 1983 to March 1984) The Nairobi region with its complex land scape was chosen as the area for the study, covering approximately 60 km x 60 km. The boundaries extend from Limuru to Athi River and from Ngong Hills to Thika excluding the Gregory Rift Valley (Figure 1). Nairobi is the capital city of Kenya and the fastest growing and most influential city in Eastern Africa. The population growth over the period 1984-1988 is expected to be 7,6% per annum,including 2,6% as a result of ru ral-urban migration (Government of Kenya 1983). This implies that the population will double in 10-12 years. The demands for hou sing, services, work, water, food and energy are increasing rapidly. Located on the edge of the slopes of the Aberdares and the Athi-Kapithi Plains, Nairo bi manifests a variety of land-use conflicts. Some of these are inherent in the location at the interface between the pastoral socie ties developed on the plains and the agri cultural societies developed in the highlands, others are more complex conflicts resulting from the many possible uses of productive land in a metropolitan area. 2 MATERIALS AND METHOD 2.1 Materials The study was limited to readily available materials. A photographic enlargement at 1:100.000 scale of LANDSAT false colour com posite (FCC) transparencies for the Nairobi area formed the basis for this study. The study area is shown on LANDSAT images 180/61 of January 24th, 1976 and 181/61 of January 25th, 1976. A black and white print of band Figure 1. Location of the study area.
