Abstract
The study was on the investigation of land-use changes between 1965 and 2003
in the northern part of Kaduna metropolis using remote sensing (RS) and
geographic information system (GIS) techniques. Sources of data were primarily
air-photos of 1965, 1977 and 1992. The air photos were of different scales but
the use of the “dot grid” method helped to consistently identify, sample and
estimate proportions of each air-photo year mosaic that had specific land-use
types model by model. Landuse changes between 1992 photo-year and 2003
were obtained through digital mapping techniques using Global Positioning
System instrumentation: GPS – “Magellan 315” because air photograph of the
area was not available for this period and Satellite imagery (strip or spot) was
very expensive.
The results of the study showed that between 1965 and 1977, and 1992
land-uses changed from rural features to those of urban development indices and
very rapidly. Urban residential land-uses for example leaped from 62.5ha. in 1965
to 202ha. in 1977 to 392ha., and from 1992 to 507ha. in 2003. Similarly
staggering rises were observed in government owned institutional lands and
commercial services land-uses. The rises were rapid and higher between 1992
photo year and the digital mapping of year 2003 than any previous successive
photo years and ranged from 84% for urban road/highway development; for
residential it was 122% to 268% for commercial services. The trend was clearly
from rural to urban land-use development. However, the increases were complex
and confused with ever threatening risks of high magnitude disaster on the
leading edge of urban land-uses
