Urban Vegetation Study of Kaduna Metropolis using GIS and Remotely sensed Data

Abstract

Kaduna metropolis is an example a careful urban planning by the colonialists in 1920’s which gradually deteriorated in quality due to poor development control and city management. This study on urban vegetation using Remote Sensing and GIS technique was a follow up on Al-Amin 2005 which used quadrant urban vegetation was studied by the quadrant method. The use of GIS technique has revealed several minute details that were not exposed by the quadrant study of 2005. The analysis shows that only 1.267km2 out of the total study area segmentation of 11.832km2 are covered with a regular pattern vegetation distribution. This only constituted about 10.72% vegetation area while 89.28% Lack vegetation. The study also shows that part of the study area that are without vegetation was (89.28%) equivalent to 10.56km2 is densely populated with high commercial activities and high traffic, while the area classified with vegetation cover (10.72%), equivalent to only 1.267km2 has scarcity population with very low commercial activities and low traffic. This situation is attributed to people’s adaptation to a city without vegetation and seems to lack or ignore its consequences.
