As Chisholm (1979) pi40 says "Any technical change creates conditions of disequilibrium which may be of long or short duration according as the innovation in question is or is not major, and also according to the nature of the adjustment mechanism". One technical change that certainly started to occur between the chose dates is the increase in accessibility of most areas due to better roads and the introduction of small vehicles. These show up in the correlation between the proportion of woodland in a particular area and its distance from its potential consumers, mainly in Kaduna. Accessibility correlates in a strong negative way with the percentage of woodland in 1972, while in 1950 the relationship was in the opposite sense. 10.2 Farmland, as would be expected, is more plentiful near to a road or a railway station, significantly correlated in 1972, less so in 1950. Other factors are at work here. As with respect to Kaduna, the correlation is significantly high in both years with time. This shows that topographical and soil factors in the S.E. of the test area may restrict farming activities. 11. CONCLUSION Using sample from aerial photographs and dot grids it is possible to estimate land use changes in savannah areas with acceptable precision. Studies of this nature could provide a useful inexpensive way of obtaining land resources information in developing countries.
