Abstract
LULCC is the quantitative changes in the area extent that is increase or decrease of a given type
of LU and LC. In Ethiopia LULCC has been recognized as an important driver of environmental
change in the country. Therefore a systematic analysis of LULCC is so crucial in order to
understand the extent of the change and take necessary measures. The main objective of this
study was to understand the LULC dynamics of Chi/alo Mountain and its environs. More
specifically, the study analyzed the LULCC over the past 38 years, assess the impact of LULCC
on biophysical and socioeconomic factors and identifY drivers of LULCC in the study areas. The
study has made use of sequential satellite images (1973, 1986, 2000 and 2011) and the analysis
" carried out using RS and (GIS) in conjunction with field verifications. Moreover socio-economic
surveys were also used to interpret the drivers of LULCC and associated negative impact
occurring on both biophysical and local community. Accordingly the LULCC analysis showed
forestland is continuously decrease during the three comparison period i.e. (1973-1986), (1986-
2000) and (2000-2011) with (20.54 %), (19.61%), and (28.24%) re;pectively. On the other hand
crop land showed continuous increment by (9.87 %), (5.92 %), and (59.86%) during the three
period. The remaining LUiLC class showedjluctuation, thus increased one period and decreased
on other period. The major causes of LULCC in the study area are; deforestation, agricultural
expansion, scarcity of farm land, demand for wood, population growth, and fire hazard. These
leads to distraction of natural resources such as reduce the availability jlora andfauna, soil
degradation, climate change and decline of water resources. It also negatively affects the local
:l community through decline livestock number; increase reliance on chemical fertilizer, shortage
of water, wood and medicinal plants. Thus in order 10 alleviate the problem possible measure
must be taken such as control rale of population growth, agro-forestry, aforestation &
reforestation, creating off farm job opportunity etc must be undertake.
