The collateral materials came frem the following sources: extracts iron the periodic economic survey reports convering the Northern Region (CBS 1979-1981); annual reports of agronomic and farm mechanization trials in agricultural stations and on-farm projects; technical reports on forestry, fisheries crop deve lopment, livestock and wildlife potentials of the Northern Region (NORRIP Tech. Reports, 1983). Frcm the daily newspapers and radio forum came those relevant nieces Q f news about land development and the environment. Also a special aerial surveillance flight was organized primarily to match the 1975 FCC information with the 1984 terrain details in order to estimate the general trend of the land use situa tion over the ten year period. The effectiveness of this last activity was however hampered by the lateness of the recce flight which came four weeks after the imagery date. This interval of time spelt so much changes in the landscape due to early on-set of the dry season and the'rapidspread of bush fires. There was also overcast of harmattan fog which redu ced visibility considerably. Notwithstanding the problemsencountered in the aerial recce flight,it was possible to have impressions of those broad changes that had occured, though these could not be mapped on the basis of the data at hand. Finally the 1970 and 1984 population census figures were integrated with landsat data. A supportive stere oscopic interpretation of the existing, though out dated aerial photographs, of the 1960's situation, was carried out to verify the landform characteris tics of the photcmorphic units which were delineated with the FCC.

Upland range terrain Mainly woodland with hebaceous undergrowth Dominantly red to reddish orange and sandy texture Mainly covered with shurb savannah Balanced mixture of green and orange mott- lings on yellowish background PHOTCMORPHIC ANALYSIS OF LAND OCCUPATION ZONES In the FCC imagery, one could discern a number of descriptive landscape elements. These and their FCC characteristics of tone, colour ranae, texture and pattern were photo-keyed (Table 1) and applied to differentiate the landscapes into photographically hemogenious units. The interpretative elements, when they were taken simultaneously together, defined those fairly homogenous unit areas into photcmorphic unit (Leighly, 1965, MaccPhail, 1971) These units on the FCC imaaery were delineated into four broad intensity levels of land occupation.
