ABSTRACT
Land cover alteration is major issue of global environmental change. This change is due to human
intervention for various activities. The change is a gradual process and it takes time depending on
the drivers. Basin level land cover dynamic has been supposed to be the most earliest of all human
that brought environmental changes. Thus, trends and drivers of land use land cover dynamics in
basin are the key considerations in the research. To detect the trends of the change, TM (1989),
ETM+ (2004) and ETM – OLI (2019) Land sats were used. The trends of land cover dynamics that
happened from 1989 to 2019 were analyzed using ERDAS 2015 and arc map 10.5. In addition, the
drivers that supposed to accelerate the changes were identified by questionnaire, focus group
discussion and interviews. In the period comparisons between 1989 and 2019, the farmlands &
settlements and bush & shrub lands are increased by 4684.36 and 10496.28 km2 with rate of 104.09
and 233.25 km2 per year respectively. In contrast, the forest areas and grasslands & degraded lands
are decreased 6770.20 and 8410.44km2 with rate change of 528.83 and 186.89 km2 per year
respectively. Regarding to the factors that accelerated the changes are population pressure, open
grazing activities, lack of professional natural resource managements, weak governmental regulations
on forest resources, effect of climate change, and increasing of unemployment. Thus, it is
recommended that strategies should be designed for the pastoralists sector due to decreasing trends
of forest and grassland in the basin.
Key words: Drivers, Dynamics, Land Cover, Land Use, River Basin, Trends
1. Introduction
1.1. Background of the Study
Land use and land cover alteration is major issues of global environmental change (Parksam, 2010)
due to human intervention as a driver for various processes (Batar et al., 2017; Meneseset al., 2017;
Baral et al., 2009; Woldeamlak, 2004). Such as for agricultural, settlement, transportation,

infrastructure and manufacturing, park recreation uses, mining and fishery (Ellis 2011). Starting from
the domestication of plant, animals and control of fire, humans have been changing the topography
in an irreversible state (Bone et al., 2017; Lambin et al., 2003). Nonetheless, in the world history, an
abrupt and huge land use change has been begun in the 17th century related with agricultural
expansion and industrial revolution (Goldewijk & Ramankutty, 2003).
Land use land cover change in the river basin has been supposed to be the most earliest of all
human that brought environmental changes (Solomon et al., 2017; Thapa-Magar and Shrestha, 2015;
Gebresamuel et al., 2010). In the globe, land use land cover history in the river basin is quite
dynamic (Nejadhashemi et al., 2011) both temporally and spatially with respect to the sustainable
socio economic development of human beings (Koch et al., 2012). For example the developed
countries, land use land cover change in river basin level had been become stable before fifty years
ago (Wang, 2006). Ironically, the land use land cover change process in the river basin in the
developing world is still in progress, which devastated their natural resource, facing a challenge on
their sustainability (Goldewijk & Ramankutty, 2003).
In Ethiopia, land degradation and deforestation are the most agents for land use land cover change
(Moges and Holden, 2009; Gebresamuel et al., 2010; Zeleke and Hurni, 2001; Alemayehuet al.,
2009). Empirically, deforestation rate is guessed to be between the range of 150,000 and 200,000
hectare per year (Zeleke and Hurni, 2001). This makes the average annual rate of deforestation in
the country 0.8 up to 1.05 % per year (Earths Trend, 2003). In the Ethiopian highlands, because of
population growth and shortage of agricultural land, encroachment of farm lands (Woldeamlak,
2004) has been shifted to semi marginal and marginal lands in the last fifteen years than ever before
(McKee, 2000; Tesfaye, 1999). For instance, in southern Ethiopian, in the Abaya-Chemo sub-basin
of the study conducted by Mengistu (2009) showed that a significant rate of change from forest land
into farmland. The farmland and settlement had increased by about 72% while the forest cover
decreased by 17% within less than a decade. Land cover changes are caused by a number of human
driving forces (Meyer and Turner, 1994), which is also true for southern Ethiopia (Mengistu 2008;
Genene and Ramachandra, 2015). In relation to this, traditional and modern way of mining
exploration becomes one of the driver of land use land cover dynamic in southern Ethiopia (Reid et
al. 2000). In addition, the rate of deforestation in southern parts of Ethiopia is by far reaching climax
point at the moment time due to encroachment of farm lands, firewood, lumbering and home
construction (Mengistu 2008; Dessie & Christiansson, 2008). Thus, an understanding of the trends
and drivers of land use land cover change is essential for tackling future prospect of land use and

land cover dynamics driven impacts on socio-economic development (Pullanikkatil et al., 2016;
Bhattarai et al., 2012; Schreier et al., 2003; Rechard, 2005).
Having derived by these views, this study assesses the drivers, trends, patterns and, extents of land
use land cover dynamics in the south eastern Ethiopia with particular reference to Dawa river basin.
The study area is one of the drought prone areas where land use and land cover change is reaching
of a critical stage due to drivers. As the result of the existing driving forces of land use land cover
change in the study area, forest coverage and grass land areas are greatly decreased and imposed
critical influences for grazing on the pastoralist (Dessie and Kleman, 2007; Dereje, 2007; Mengistu,
2008; Dessie & Christiansson 2008).Furthermore, the area is marked by diverse topographic
conditions, which provides an opportunity to analyze trends and drivers of land use land cover
dynamics in Dawa river basin since 1989.
2. Materials and Methods
2.1. Location and Descriptions of the Study Area
The study lies between 405’8’’ to 60 27’ 18’’N and 3802’ 48’’ to 4102’ 34’’E. In administrative term, it
covers 11 Woreda from both Oromia and Ethio-Somali Regional states. These are Uraga, Bule
Hora, Yabelo, Arero, Odoshakiso, Liben, Filtu, Moyale, Dire, Bore and Adolana Wadera Woreda.
The study area has special coverage of 42,202km2 and the basin is located around 567km southwest
of Addis Ababa and forms the parts of the southeast highlands of Ethiopia. The following Map
helps clearly to show the location of the study area.
The study area is consisting of different topographic conditions. The elevation ranges from 323 to
3011 m.a.s.l. The study area is characterized by mountainous and highly dissected stretches of land
with steep slopes at the upper stream part while an undulating terrain and gentle slopes at the
downstream part. Mixed types agriculture on subsistence scale is the major livelihood of the people
in the study area. Land and livestock are the most important assets of the people, with which they
lead a sedentary life. A Variety of crops are produced by a house hold.
According to the National Meteorological Agency as measured at Negele town (5019’ 58’’N and
39019’ 27’’E with elevation 1496m), the climate condition of Dawa basin is generally characterized
by sub-tropical and tropical agro ecology with the mean rainfall of 600mm to 1250mm (for the year
between 1989 and 2019) and the average temperature of the study area is 15 to 22.80c (for the year
between 1989 and 2019). The study has four seasons. These are summer, winter, autumn and spring.
Summer is the main rain rainy season while winter is a dry season in the study area.

The study area is consist of different topographic conditions, which is characterized by mountainous
and highly dissected stretches of land with steep slopes at the upper stream part while an undulating
terrain and gentle to level slopes at the surface part. The elevation ranges from 323m to 3011 meter
above sea level. According to FAO, 1999 classification the topography of the study area consists of
level slope 19822.36km2 (46.97%), very gently slope 9483.16km2 (22.47%), gentle sloping
6902.92km2(16.35%), sloping 4148.44km2(9.83%), strongly slope 1611.64km2(3.82%), moderate
steep 221.16km2(0.53%) and very steep 12.16km2 (0.03%). Most parts of the study area are found
within level slope while small parts of the study area are just found in very steep slope.
The livelihoods of the majority of the settlers in the study area are mainly depending on pastoral
practices. In addition, mixed types agriculture on subsistence scale is the major livelihood of the
people in the study area. Land and livestock are the most important assets of the people, with which
they lead a sedentary life. A Variety of crops like Maize, Enset, Coffee, banana and etc. are produced
by house hold. Moreover, settles who live in urban areas depend on trade.

2.2. Data Sources and Methods of Collection
2.2.1. Satellite Data
The data used to create the spatial data base used for this study were obtained from the Ethiopia
Map Agency which were taken in 1989 (TM landsat-5), 2004 (ETM+ Landsat-7) and 2019 (ETM
landsat-8 OLI) during February months. These years and months were selected in order to have a
clear difference with in each land use and land cover categories of the area for supervised

classification. ASTER DEM 30 m*30 m resolution was downloaded from USGS website and was
used for basin delineation and slope generation. Even though all the land sat images are freely found
in the website addresses, due to lack of experience and internet access to extract and down load the
images, the necessarily data were directly purchased from EMA.
2.2.2. Field Data Measurements and Observations
The field data collection were done randomly to verify the classified image and to collect the
necessary land use and land cover data for accuracy assessment. In addition, random field data,
ground control points, were collected to validate the pour points of the streams in the basin.
Ground control points were collected using Garmin Global Position System model 72 devices.
2.2.3. Sampling Techniques and Size Determination
The intended objective was achieved from the result of focus group discussion, interview and
questionnaire. Focus group discussion and interview were selected than other methods of obtaining
information because the researcher strived to lead the discussion by moderator. Thus, to identify the
possible deriving factors of land use land cover change in the earlier times, elders of the local areas
(kebele leaders, administrative officials, illiterate farmers who have changed their crop land to other
land use types and the like), were planned to discuss and interviewed. The main reason that the only
elders of the local areas were selected for the discussion and interview than other social group was
that they have lived a long periods of time and have a chance to observe a significant temporary land
use land cover change starting from earlier time within a given study time interval in the study area.
Questionnaire also distributed to the target population in the study area. This was to gather
additional causative factors of LULCC from the social groups in the study area and the
questionnaires were distributed in the selected districts. Hence, in the process of selecting sample
population for the purpose of questionnaire, purposive sampling technique was considered. In the
study area there were 11 Woredas. From 11 Woredas in the study area, 6 districts were selected
purposefully based on the strength of the LULCC exhibited in the study area.

The study area has a total of 843,343 populations. Hence, the sample size was 100 (Table 1). Finally,
In order to determine the weight of sample size in each Woreda, the total sample populations were
distributed proportionally in to the respective Woreda’s by using proportionality scientific formula
(Cochran, 1977) given below.
Finally, the number of population for each district was collected from the respective Woreda’s
administrative offices. In order to determine the sample size in each district, the total sample
populations were distributed proportionally in to the respective districts by using proportionality
scientific formula given below (Cochran, 1977).

Where, ni=the number of sample population on each sample district.
Ni=the number of population in each district.

Thus, the possible Drivers land covers land change in the study area identified by the selected
sample size populations. Finally, the results of the group discussion, interview and questionnaire
were become an input for the identification of possible drivers of Land use land cover change
performed in the Dawa river basin.

The questionnaires were pretested and administered by the researcher, extension workers (DA’s)
and high school teachers who were recruited from each sample districts and a total of 25 individuals
involved in answering the pretest questionnaires.
2.2.4. Methods of Data Analysis
2.2.4.1. Satellite Data and Image Classification
Pre-processing: The pre-processing activities such as layer stacking, haze correction and
topographic correction were carried out on the satellite images using ERDAS IMAGINE 2015. The
land sat images were extracted by mask with the study area DEM by arc map 10.5.
Image Classification: Supervised image classification systems were carried out using ERDAS
IMAGINE 2015 after preprocessing activities. Finally, farmland and settlements, forest, grassland
and degraded land, bush and shrub lands were produced corresponding to the three reference years
and the result sent to Arc GIS 10.5 software to display, quantify and interpret. The cultivated land
and settlements were merged in to one category because it was awkward to recognize the scattered
rural settlements as a separate land cover type. Also, cultivated land exists around homesteads and
would have to be recognized as such. Hence, for practical reasons, the two land cover types were
merged in to one category. In addition, grassland and degraded land includes both open grazing
lands and exposed lands. It was difficult to distinguish because the bare lands were identical with
grazing lands, which were heavily degraded in the study area. As a result, they were categorized
together (Table 2).

2.2.4.2. Field Data Analysis
Ground control points were collected for the purpose of undertaking accuracy assessment to
validate and compare the classified images with the true geographical phenomena. After the ground

of geographic phenomena. Finally, after land use and land cover change of the study area processed,
analyzed and interpreted, the drivers of the land use land cover changes supported with the result
obtained from questionnaire, informal interview and focus group discussions.
Accuracy Assessment: After the supervised classification has taken place on the land sat image,
accuracy assessment has also under taken to compare the classified images with geographical data
that they are assumed to be true. The accuracy assessment of the LULC map have been under taken
by comparing the field data collected by GPS with the classified images in ERDAS IMAGNE 2015
software . Four lands used and land cover classes were identified using visual image interpretation
and field survey. Thus, from the supervised digital image classification, in this study, accuracy
assessment was done for the 2019 satellite images. The overall accuracy was calculated by summing
the number of pixels classified correctly and divided it with the number of pixels. Thus, the overall
accuracy of 2019 satellite image was 97.76.
Land Use and Land Cover Detection: The amount of different land use and land cover types of
the study area quantified from the produced maps, which depicted in percentiles. A combination of
information collected from field, local people, elders and natural resource experts through informal
interviews and focus group discussions with an information gained from satellite images were used
in the analysis of land use and land cover change detection. The land cover maps for the three
period series of images were analyzed based on land use and land cover types area comparison. The
changes over 30 years were analyzed and rate of change for each land use land cover type is
calculated. In the meantime, the rate of land use and land cover changes for the three period’s
from1989 - 2004 and 2004-2019 and 1989-2019 were computed using the following formula (Geist
and Lambin, 2004).
R =
………………………………………3
Where R= Rate of change, Q1=initial year land use/ land cover in km2, Q2 = recent year land use/ land cover in km2, T= time interval between initial and recent years.
2.2.4.3. Possible Drivers of Land Use and Land Cover Change Interpretation
Having collected the socio economic data for the study, the researcher analyzed those by using
qualitative techniques. That implies, after all the possible drivers of the LULCC in the different time
intervals had identified from the society, it was interpreted using descriptive methods by matching
with the change identified from the imageries.

3.2. Spatial Temporal Distribution of Land Use and Land Cover and Accuracy Assessment
3.2.1. Land Use Land Cover Classification for 1989
As information obtained from land sat, the land cover classification of 1989 was identified as bush
and shrub lands, farmland and settlements, forest, grass and degraded Lands. Moreover, based on
the spatial distribution, most of the farmland and settlements (534.32 km2 (1.27%)) were found in
the north parts of the study area. Most parts of the study area were covered by grass and degraded
lands (30171.64 km2 (71.49%)) and spatially they were found in the most central and south eastern
parts of the study area. In addition, the bush and shrub lands (6988km2 (16.56%)) were mostly
concentrated in the south western parts of the study area and forests (3008.04km2(10.68)) also found
in the northern parts of the study area (Figure 2 1989A).
3.2.2. Land Use Land Cover Classification for 2004
The land use and land cover classifications of 2004 were identified as bush and shrub lands
(22988.28km2 (54.47%)), farmland and settlements (2443.08km2(5.79%)), forest (2237.12km2(5.3%)),
and grass and degraded lands (13033.52km2 (34.44%)). During this time, most parts of the study area
were covered by the bush and shrub lands. Spatially, the bush and shrub lands are dominantly
situated in the central parts of the study area. Similarly, the grass and degraded lands also located
mostly in the southern edge in the study area. In the same manner, the farmland and settlements are
mostly found in most northern edge of the study area (Figure 2 2004B).
3.2.3. Land Use Land Cover Classification for 2019
Furthermore, land use and land cover classifications of 2019 were identified as bush and shrub lands
(26741.44km2 (63.37%)), farmland and settlements (4764.72km2(11.29%)), forest (694.72km2
(1.65%)) and grass and degraded lands (10001.12km2 (23.69%)). During this time, most parts of the
study area were covered by the bush and shrub lands. Spatially, the bush and shrub lands are

Accuracy Result: The result of the of overall accuracy assessment of 2019 year classified Landsat
imagery was analyzed (Table 9). As its name implies, the accuracy assessment depicted the degree of
correctness of assigning a pixel to the predefined land use and land cover classes. Therefore, the
base line requirement of the overall accuracy assessment is ≥80 (Congalton, 1991).Higher accuracy
result had obtained on the latest imagery in the software matched with the land cover classes on the
ground.

3.3. Land Use and Land Cover Change Detection 3.3.1. Land Use Land Covers Change Detection between1989 and 2004
In 1989 the farmland and settlements covered 534.32km2 and increased to2443.08 km2 in2004.So,

In contrast, in the same study years, the grass and degraded lands covered an area of 30171.64 km2
in 1989and it decreased in to 13033.52 km2 in 2004. So, in 15 years, 14056 km2 remained constant
from being changed. But, it lost 16115.64 km2 to the other class types and again it gained 477.52 km2
from the other mentioned classes. Generally, the grass and degraded lands showed a total decrement
of class change (15638.64 km2) in 15 years. Likewise, the forest covered an area of 3008.04 km2 in
1989 but it decreased in to 2237.12 km2 in 2004. In these years, 2226 km2 remained constant from

within 15 years, it lost 4605.24 km2 to the other classes and it again gained 72.84km2 from the other
class types. Generally, the grass and degraded lands showed a total reduction of class change (3032.4
km2) in 15 years (Table 11B).
3.3.3. Land Use Land Covers Change Detection between1989 and 2019
The overall change in land use and land cover in the last four decades was also assessed. There were
an increment of farm land and settlements and bush and shrub lands but a decrease in the area
coverage of grassland/degraded land and forests. This was just the general impression of land cover
dynamics based on comparison of individual land cover type.
The farmland and settlements portrayed increasing pattern of change during the period comparisons
of between 1989 and 2019 .It increased from 80.36 km2 to 4764.72 km2 in 1989 and 2019
respectively. Within 30 years, farmland and settlements was converted from bush and shrub lands,
forests, grass and degraded lands accounted for 3508 km2, 1148 km2 and 55.72km2 respectively.
Thus; within 30 years, it gained 4711.72 km2 from the other classes. In addition, bush and shrub
lands was showed increasing pattern of changes during the periods between 1989 and 2019. It
increased from 16230.16 km2 to 26741.44 km2 and lost 3552.92 km2 to the other land types mainly
to farmland and settlements (Table 11C).
In contrast, the forest portrayed decreasing pattern during the period comparisons of between 1989
and 2019. It decreased from 7464.92 km2 to 694.72km2 in 1989 and 2019 respectively. Within the
entire study time, the forest was changed mainly to bush and shrub lands which account 5622.2 km2
and 1148 km2 respectively. Similarly, grassland and degraded area showed decreasing pattern during
the period comparisons between 1989 and 2019. It decreased from 18411.56 km2 to 10001.12km2
between 1989 and 2019 respectively. Within the 30 years, it lost 4882.72 km2 to other land types
mainly to bush and shrub lands and farmlands and settlements (Table 11C).
Generally, during in the period comparisons among 1989, 2004 and 2019, the farmlands and
settlements were increased by 4684.36 km2with rate of 104.09 km2 per year. In addition, within 30
years, bush and shrub lands were increased to 10496.28 km2 with rate change of 233.25 km2 per year.

3.4. Drivers of Land Use and Land Cover Change between 1989 and 2019
Land cover changes are caused by numbers of natural and human deriving forces (Li et
al.,2016;Myer and Turner II, 1994).Whereas natural effects such as climate change are felt only over
a long period of time; the effects of socio-economic factors are immediate and radical for LULCC
(Woldeamlak, 2004). Moreover, population growth was the most important derivers for land cover
change of the human factors in Ethiopia (Hurni, 1993), as it was generally the case in
underdeveloped countries (Hurni, 1993).
According to questionnaire, focus group discussion and interviews made with local people, the
most influential socio- economic, political and natural factors that have speeded up the conversion
of specific class type to the other from the year between 1989 and 2019 were population pressure;
open grazing activities, lack of professional natural resource managements, deforestation, weak
governmental regulations to wards forest resources, effect of climate change and the day to day
increasing of unemployment in the basin.

4.1. Drivers of Land Use and Land Cover Change
Farmland and Settlements: This class has included cultivated land and settlements. The land cover
types were merged in to one category because it was awkward to recognize the scattered rural
settlements as a separated land cover type. Also, cultivated land exists around homesteads and would
have to be recognized as such. Hence, for practical reasons, the two land cover types were merged in
to one category. The areas under the farmland and settlements have showed a slow and persistent
increase over the period under the study. Though this was a general trend, the rate of increase was
quite small while compared with the total area of the basin. This land use land cover showed
increasing pattern of change.
The farmland and settlements showed increasing pattern of change during the first period
comparisons of 1989 to 2004.The farmland and settlements have converted mainly from grass
/degraded lands, forest areas. According to questionnaire, focus group discussions and interview
conducted, the farmland and settlements increased between 1989 and 2004 due to purely population
pressure occurred in the study area for the purpose of cultivation. Due to above mentioned reasons
the farmland and settlements were increased during the period of comparison had made.
Similarly, the farmland and settlements showed increasing pattern of change during the second
period comparisons of 2004 to 2019. Farmland and settlements have converted mainly from

woodlands, grass lands and forests. According to questionnaire, focus group discussions and
interview conducted, the farmland and settlements were increased between 2004 and 2019 due to
the illegal encroachment of the local population in to the grass land and forest areas for cultivation
purpose. Due to the above stated reasons the farmland and settlements were increased during the
period as comparison had made. Generally, the farmland and settlements were increased in between
2004 and 2019 due to purely population pressure. To sum up, the justification of the informants is
similar with Haile (2004) and Gebresamuel et al. (2010), which caused much of the open grazing
land and forest to be shifted in to cropland illegally.
Forest: The area under the forest showed a persistent decrease in the first two years study intervals
and increase in the last study interval over the period under the study. Though this was a general
trend, the rate of decreased was quite high when compared with the total area of the basin.
The area of land that was occupied by forest depicted decreasing situation in the periods between
1989 and 2004. The forest has mainly converted to farm lands and bush/shrub lands. According to
questionnaire, focus group discussions and interview conducted, the forest decreased between 1989
and 2004 owning to illegal cutting of the forest for personal consumption. This justification strictly
matched with Yigremew (1997), which has helped the people to open the way to extract out the
natural indigenous forests for the purpose of constructing the dwelling houses for the whole family.
Due to above mentioned reasons the forest was decreased during the period as comparison had
made.
Similarly, the forest showed decreasing pattern of change during the second period comparisons of
2004 to 2019. The forest was changed mainly to bush lands and farmland/settlements. Based on
information conducted through questionnaire, focus group discussions and interview, forest lands
decreased during this period due to the most recent advancement of charcoal ways of production by
the local community in the basin. This reason is strictly matched with Yigremew (1997). In addition,
the existing government also exploited the forest resource from the basin area forests for the name
of rehabilitating the war devastating regions and this situation opened the way for further
deforestation for the local community. Moreover, according to questionnaire, focus group
discussions and interview conducted in the study area, the community considered the forests
resource as the source of income gaining area via selling the forest for the purpose of fire wood to
the nearby urban areas and the increasing demand of the forest charcoal by the urban dwellers paved
the way of forest destruction by the local community as a daily income especially by the youngster

ladies. This justification agreed with Woldeamlak (2004).Due to the above stated reason the forest
areas were decreased during the period as comparison had made.
Grass and Degraded Lands: Degraded land included both open grazing lands and exposed lands.
This is because, it was difficult to distinguish open bare lands from grazing lands as they were
heavily degraded in the study area. As a result, they were categorized together.
The area under the grass and degraded land showed a decreasing pattern of change during the first
period comparison in between 1989 and 2004. The grassland and degraded land have converted to
bush and shrub lands; farmland and settlements. According to information obtained from
questionnaire, focus group discussions and interview the grassland was converted mainly to bush
and shrub lands, and farmlands between 1989 and 2004 due to the effect of climate change and
population pressure happened in the basin. Due to above mentioned reason the grassland and
degraded lands were decreased during the period as comparison had made.
Moreover, Grass lands and degraded areas showed decreasing pattern during the second period
comparisons of 2004 and 2019. The grasslands have converted mainly to farmland/settlements,
bush and shrub lands. Based on questionnaire, focus group discussions and interview made with the
local people in the basin, the grass and degraded lands converted to bush and degraded lands due to
mainly the effect of climate change in the basin. This resulted in the favorable condition for the
encroachment of bush and shrub by intermingling deep in to the grass and degraded lands
overwhelmed it. Thus, it decreased the grass and degraded lands. The other main reason for the
decreasing of the real extent of the grass and degraded lands was population pressure, which have
caused much of the open grazing land shifted in to cropland. This agreed with the findings of the
previous conducted findings (Amsalu et al., 2007; Gebresamuel et al., 2010; Zeleke and Hurni,
2001). The remaining area now consists largely of bare ground, which is overgrazed and
characterized by exposed rocks, thus; decreased the grass and degraded lands.
Bush and Shrub Lands: These types of vegetation have covered the fringe of forest vegetation and
sprawled towards the grassland and degraded land. They showed increasing pattern of change during
the first period comparisons of 1989 and 2004. The bush and shrub lands have converted from
grasslands/degraded lands and forests.
Based on questionnaire, focus group discussions and interview made with the local people in the
basin, the bush and shrub lands increased in between 1989 and 2004 owning to the climate change
occurrence in the basin. This favorable condition assisted to the encroachment of bush and shrub by

intermingling deep in to the grass and degraded lands, resulted in the grass and degraded land areas
automatically transformed in to bush and shrub lands, thus; expanded the bush and shrub lands.
The bush and shrub lands converted mainly from grass and degraded lands and forests. It increased
during the second period comparisons of 2004 and 2019. Based on questionnaire, focus group
discussions and interview made with the local people in the basin, the bush and shrub lands
converted from grass and degraded lands due to mainly the recent serious occurrence of climate
change in the basin. This has resulted in the favorable condition for the encroachment of bush and
shrub by intermingling deep in to the grass and degraded lands. Owing to this conversion of the
grass land to the bush and shrub lands frequently grass shortage was occurred year from year on
pastoralist.
Based on questionnaire, focus group discussions and interview made with the local people in the
basin, the bush and shrub lands converted from forest due to population pressure. Population
pressure is one of the headache agents of deforestation in the basin. In the basin, the community
considered the forest resources as the source of income gaining area via selling the forest products
for the purpose of fire wood to the nearby urban areas and the increasing demand of the forest
charcoal by the urban dwellers paved the way of forest destruction by the local community as a daily
open income gaining area especially by the youngster ladies. This illegal deforestation made the
forest area to be degraded and changed in to bush and shrub lands. Thus, it increased the bush and
shrub lands.
5. Conclusions
In Dawa river basin land use and land cover changes have occurred since 1989. As a result, during in
the periods comparisons among 1989, 2004 and 2019, the farmlands and settlements were increased
by 4684.36 km2 with rate of 104.09 km2 per year. In contrast, the forest lost 6770.2 km2 within the
entire time intervals with rate change of 528.83 km2 per year. Similarly, the grasslands and degraded
areas lost 8410.44 km2 within 30 years with rate changes 186.89 km2 per years. Moreover, during the
periods of comparison, bush and shrub lands increased 10496.28 km2 with rate change of 233.25
km2 per years. Thus,the major change has observed in increasing of farmlands and settlements at the
expense of other identified land classes especially on woodlands, grasslands and forests in the study
area. According to the key informants, focus group discussion and questionnaire the major drivers
that had accelerated the change were effect of climate change, deforestation, population pressure,
and lose governmental policy. Generally, as the result of the existing driving forces of land use land

cover change in the basin, forest coverage and grass land areas are greatly decreased and imposed
critical influences for grazing on the pastoralist.
6. Recommendations
The findings of the study gives clue for the concerned body including researchers and other
stakeholders for further better investigation on the issues and bring possible intervention
mechanisms for the dramatic land use land cover change in the study area.
According to the result of the study done in Dawa river basin, the following recommendations has
been forwarded. The study tries to see starting from 1989 to 2019. Thus, it needs to be assessed
using before 1989 imageries. In addition, the study points that settlement & farmlands and grass
/bare lands are merged together during image classifications due to low image resolution. Thus, it
needs to be classified independently using high resolution SPOT images. Moreover, the study tries
to investigate only the drivers of land use land cover change in Dawa watershed but it needs to be
investigated on the socio-economic impacts of land use land cover change. Similarly, the study tries
to identify the drivers of land use land cover change in some selected districts but it needs to be
identified in all districts of the study area. Finally, forest and grasslands areas greatly decrease from
time to time than the other class types in the study area. Thus, strategies should be designed for
these specific cover types to recover back in their coverage in the basin.
