409 Symposium on Remote Sensing for Resources Development and Environmental Management / Enschede / August 1986 Development of a regional mapping system for the sahelian region of west Africa using medium scale aerial photography Steven J.Daus, Mamane Guero, François Sesso Codjo, Cecilia Polansky & Joseph Tabor Resources Inventory and Monitoring section, Forestry and Land Use Planning project, Niamey, Niger ABSTRACT: In response to an expressed need by the government of the Republic of Niger, a systematic mapping procedure was developed to determine the surface area of forest lands in Niger. The objective was to develope an approach suitable to: 1) the nature and value of the resources to be mapped and evaluated, 2) the available source, or base, data, and 3) the technical capability of the Nigérien forestry personnel. The approach included, regional stratification using LANDSAT MSS imagery, collection of ground data, and extrapolation of this point specific data to the entire study area with the aid of a photo interpretation key developed for the region. RESUME: Selon des besoins precise par le governement de la Republique du Niger une procedure de la cartographie systématique a était develope afin de determiner la superficie des terrains forestier au Niger. L’objective était de établir et mis en oeuvre un system adapte a: la nature et valeur des ressources dresse, les données de base disponible, et les capacitees techniques des cadres forestiers du Niger. L'approache compris d'une delimitation regionelle a partir des images satellites LANDSAT, collection des données de terrain et extrapolation des données des sites jusqu'au niveau de la zone d'etude entire aide par une clef standard d'interpretation des photos aeriennes. 1.0 INTRODUCTION The results presented in this paper are those from work completed at the Resource Inventory and Monitoring (RIMS) section of the Forestry and Land Use Planning (FLUP) project. This project is funded under the cooperative agreement #683-0230, between the United States Agency for International Development (USAID) and the government of the Republic of Niger (GON). The primary aim of this bilateral project is to establish within the National Forest Service (NFS) of the GON a unit capable of conducting resource inventories and provide technical assistance regarding forest management practices. This unit, the Office of Technical Assistance (OTA), would contribute information and technical assistance primarily at the planning level within the GON. The RIM section was established within the structure of the FLUP project in order to: 1) develop and implement resource inventory methods appropriate to the various information needs of the GON, and 2) train GON forestry personnel in the planning and conduct of such inventories. It is intended that the developed capability of the RIM section, both the procedures instituted and the personnel trained, will become an integral part of the OTA. 2.0 SURFACE AREA OF FOREST LANDS: A PRIMARY INFORMATION REQUIREMENT IN NATURAL RESOURCE PLANNING AND POLICY A primary information requirement when conducting forest resource use and management planning is the total area covered by forest vegetation, and it's distribution within the area of interest. An estimate of 14,000,000 hectares of forested land has been put forward, but, this estimate was not based on a systematic mapping or estimation procedure and, as such, has not been incorporated in specific forestry policy or management decisions. The provision of this information was identified as one of the tasks to be addressed by the FLUP project and the RIM section, specifically. 3.0 DETERMINING THE SURFACE AREA OF FOREST LANDS 3.1 Selection of the basic approach When considering the various alternative procedures for determining the surface area of forest lands in the Republic of Niger several aspects are important. First of all there has been very little precedential application of large area inventories in the Sahel. Therefore, few results exist with which to compare one approach with another. A second consideration is the combination of the relatively low economic value of the resource and it's low concentrations. This eliminates from consideration approaches which have high costs per unit of area inventoried. A third is the appropriateness of the approach in the context of the capabilities of the GON forestry personnel being trained. The approach cannot include or utilize procedures which are highly complicated, rely heavily on the judgement and experience of the inventory specialists, or require equipment which is difficult to operate and/or maintain in conditions found in developing countries. Lastly, the approach must maximize the use of work and/or source data in existence and available. The best approach to furnishing this information to planning specialists is to produce a map which shows geographical distribution, extent and condition of forest lands. In arid land conditions, were the subject resource is in a very low density and widely distributed, and accessibility is a problem, a proven method for generating such maps is to interpret information from several levels of remotely sensed data and combine it with limited but highly representative, ground data. This approach was used in Mali (PIRT, 1982) and successfully produced terrain condition maps over the very large study area. The specific approach selected for application in the Nigérien situation is characterized by the following elements: - general stratification of the entire zone, creating units of a certain minimum size and homogeneity using LANDSAT satellite multispectral scanner (MSS) data.
