Abstract
Human adaptive responses to climate change occur at the local level, where climatic variability is experienced. Therefore
analyzing vulnerability at the local level is important in planning effective adaptation options in a semi-arid environment. This
study was conducted to assess vulnerability of Maasai pastoralist communities in Kajiado County, Kenya to climate change by
generating vulnerability index for the communities. Data was collected using questionnaires that were administered to 305
households in the five different administrative wards (Oloosirkon/Sholinke, Kitengela, Kapetui North, Kenyawa-Poka and
Ilmaroro) in Kajiado East. Vulnerability was measured as the net effect of adaptive capacity, sensitivity and exposure to
climate change. Principal Component Analysis (PCA) was used to assign weights to the vulnerability indicators used for the
study and also to calculate the household vulnerability index. A vulnerability map was produced using the GIS software
package ArcGIS 10.2. Results showed that gender of household head, age of household head, educational level, access to
extension agents, herd size, livestock diversity and access to credit facility influenced vulnerability of the Maasai pastoralists to
climate change in Kajiado East. The result showed that the most vulnerable communities with the highest negative
vulnerability index value are Ilpolosat (-2.31), Oloosirikon (-2.22), Lenihani (-2.05), Konza (-1.81) and Oloshaiki (-1.53). The
communities with the highest positive vulnerability index values were Kekayaya (4.02), Kepiro (3.47), Omoyi (2.81), Esilanke
(2.23), Kisaju (2.16) and Olmerui (2.15). We conclude that provision of basic amenities such as good roads and electricity;
access to extension agents, access to credit facilities and herd mobility will reduce vulnerability of Maasai pastoralists in
Kajiado east to climate change and variability

1. Introduction
Many studies have been conducted on vulnerability to
climate change and its extremes and different researchers
have defined vulnerability according to their own perception.
Vulnerability to climate change was defined as “the extent to
which a natural or social system is susceptible to sustaining
the damage from climate change” [2]. It was also defined as
“the degree of system susceptibility and its inability to cope
with adverse effect of climate change and variability.
Therefore Vulnerability is a function of character, magnitude
and rate of climate change and variability to which a system
is exposed to. This also includes its sensitivity and adaptive
capacity to climate change and variability” [14].
The concept and definition of vulnerability that has been
used by different studies revolves around the explanation of
lack of adaptive capacity in both social and natural system.
Climate change vulnerability has been studied by different
scholars as a composite of adaptive capacity, sensitivity and
exposure to hazard [1, 3, 9, 24, 28]. Adaptive capacity can be
defined as the ability to withstand or adjust to the changing
context; it is the ability to implement adaptation measures
that help avert potential impacts of climate change and
variability [1, 22]. Sensitivity can be defined as the ability of
a system to be affected by climate change and its extremes; it
describes conditions that can trigger an impact or ameliorate
hazard. Exposure is the nature and change in climate

variables and extreme events; it is the physical impact of
climate change such as change in rainfall pattern or rise in
temperature range [16, 22, 25].
Climate change vulnerability can be analyzed from global
level [7, 14] to regional level [8, 1] and household level [22].
The choice of vulnerability analysis scale depends on the aim
of the research, available data and the methodology of the
study. Most of the available scientific literatures on climate
vulnerability analysis focus on national and regional
vulnerability assessment usually for national or regional
adaptation planning [13, 21]. While vulnerability analysis at
the national level is necessary for policy formulation and
national planning; household vulnerability assessment
conceptualizes how climate change and variability impacts
directly on the household members and measures their ability
to adapt. This is particularly useful for resource allocation
and planning for adaptation strategies at the local level.
Vulnerability indices are diverse for the different multiple
spatial scales and that household vulnerability assessment
can be used to demonstrate how climate change affects
livelihood of different communities [24, 26]. The aim of this
study is to measure vulnerability of Maasai pastoralists’
communities to climate change and to develop vulnerability
maps showing the levels of vulnerability of Maasai
pastoralist households to climate change and variability. This
study will assist policy makers in resource allocation and
climate adaptation planning in the arid and semi-arid lands of
Kenya.

2.1. Study Area
The study was conducted in Kajiado East Sub-County
(Figure 1). Kajiado East has a high population of Maasai
tribe and Pastoralism is the main source of livelihood to a
majority of households. The livestock breeds kept include
sheep, goat, beef and dairy cattle and donkey. About 90% of
the area is categorized as semi-arid eco-climatic zones and
rainfall pattern is bimodal. The long rains season starts in
March and this peaks in April and continues till May. The
short rains begin in October and ends in December [4, 5].
2.2. Data Collection
Data were collected using semi-structured questionnaires
administered to household heads in the five administrative
wards in Kajiado East (Oloosirkon/Sholinke, Kitengela,
Kapetui North, Kenyawa-Poka and Ilmaroro). A total of 305
household questionnaires were administered and 20 key
informant interviews conducted between October 2014 and
January 2015. Sample size was determined according to
Krejcie and Morgan (1970) method of determining a sample
size [17]. Estimation of sample size in research using Krejcie
and Morgan used the formula below to determine sample
size:
Where:
S = required sample size
X2= the table value of chi-square for 1 degree of freedom
at the desired confidence level (95%) (3.841)
N = the population size
P= the population proportion (assumed to be.50 since this
would provide the maximum sample size)
d = the degree of accuracy expressed as a proportion (.05).
Based on 1800 Maasai pastoralist households in Kajiado
east, a total of 56 villages and 305 Maasai pastoralist
household were sampled in this study
The questionnaire used for the study was divided into the
following: Household demographics, socio-economic
characteristics, source of family income, livestock and crop
production, basic amenities owned, size of land owned,
access to extension service, access to credit facilities,
perception to climate change, adaptation strategies, access to
weather information and other relevant information.
2.3. Vulnerability Analysis
This study analyzed vulnerability of Maasai pastoralist as a
net effect of adaptive capacity, exposure and sensitivity.
Vulnerability = Adaptive capacity – (exposure + sensitivity)
The integrated vulnerability assessment method was used
to analyze vulnerability of Maasai pastoralist to climate
change. This method was used in this study because it
combines both the socio-economic and bio-physical factors
to measure vulnerability to climate change and its extremes.
The integrated approach combines both internal factors of a
vulnerable system and its exposure to external hazard to
determine vulnerability. It defines vulnerability is a function
of the character, magnitude and rate of climate variation to
which a system is exposed, its sensitivity and its adaptive
capacity”. When adaptive capacity of the pastoralist
household is less than the sensitivity and exposure, the
household becomes more vulnerable to climate change
impacts and the reverse is also true, the higher the adaptive
capacity, the less vulnerable the household to climate change
impact. This method uses a combination of indicators to
measure vulnerability by computing indices and weighted
average for the selected indicators. The indicators used in this
study were selected based on researchers’ observation,
literature review of published research done in pastoralists’
communities and the opinion of the Maasai pastoralist’s
communities in Kajiado County. Community involvement is
important in selecting indicators for vulnerability analysis.
This is because vulnerability to climate change is location
specific.
The principal component analysis (PCA) was used to
generate factor scores for calculating the vulnerability index
for the households. In this study, the first principal
component is the linear index of all the variables that
captures the highest amount of information common to all
variables.
The vulnerability index was determined based on three
vulnerability components (adaptive capacity, exposure and
sensitivity. Vulnerability index of household was calculated
using the equation below:
Vi = (A1X1J + A2X2J + ……… + AnXnj) – (A1Y1j + A2Y2j + ……….. AnYnj)
Where Vi = vulnerability index
Xs = indicators for adaptive capacity
Ys= indicators for exposure and sensitivity
As = First component score of each variable computed
using PCA.
The values of X and Y were obtained by normalizing the
(1)
(2)
values of vulnerability indicators using their mean and
standard deviations. In this study, Vulnerability index was
calculated using 28 vulnerability indicators selected for
adaptive capacity, exposure and sensitivity. Vulnerability
index were generated for the 305 pastoralist household
interviewed in 56 communities in Kajiado East (Table 1).

The average vulnerability index for each community was
determined by calculating the mean vulnerability index for
the communities. The study presented the level of
vulnerability of households and Maasai communities in the
study area in a map. The vulnerability maps showing the
levels of vulnerability of Maasai pastoralist communities
(highly vulnerable, moderately vulnerable and less
vulnerable) in the five administrative wards in the study area
was produced using Geographical Information System (GIS)
software package ArcGIS 10.2. Focus group discussions and
key informant interviews with Maasai pastoralist and
stakeholder meetings were conducted in the study area to
verify and validate the vulnerability maps produced in this
study.
The level of influence of the indicators on vulnerability of
the households was also analyzed using the ordinal logistic
regression model. The model is used when results are
presented in ordinal scales, as in this study where
vulnerability is categorized into (1) highly vulnerable (2)
moderately vulnerable and (3) less vulnerable households.
The reduced form of ordinal logistic regression used in this
study as described by Green (1997) is given as:

Where Y = Level of vulnerability and involves ordered
vulnerability categories, Y = 1 was given to highly
vulnerable households, Y= 2 was given to moderately
vulnerable households and Y= 3 was given to household
less vulnerable households. Y* is the given state of
vulnerability. The Xij are the explanatory variables
determining vulnerability level. βs are parameters estimated
and Uij is the disturbance term.

3. Results and Discussion
Vulnerability indicators and expected direction with
respect to vulnerability
The vulnerability indicators used for this study are presented
in table 2. The indicators were selected jointly by the
researcher and the Maasai communities. These vulnerability
indicators were categorized according to the definition of
vulnerability as a function of adaptive capacity, exposure and
sensitivity. In this study, the adaptive capacity is represented
by wealth, infrastructure, access to information, literacy level
and household size and the number of dependents. Wealth
enhances the ability of communities to cope and recover from
climate extremes. Size of herds, size of land owned and
mobility of livestock are indicators used by Maasai pastoralist
to assess the level of wealth of pastoralist households [21].
Availability of basic infrastructures plays an important role in
adaptation to climate change. It increases the ability of rural
dwellers to diversify their sources of income thereby
enhancing their adaptive capacity. Likewise, availability of
hospitals can enhance the provision of preventive treatments
for diseases associated with climate change such as malaria
and meningitis [18].
In this study, sensitivity is represented by level of
education, household size, gender and age of household head.
It is believed that the level of education of the household
head impact on the sensitivity of the household to climate
variability and change. It has also been reported that
households with smaller size are more likely to withstand
climate change and its extreme [22]. Exposure in this study is
represented by the frequency of extreme climatic events such
as droughts and floods and also by change in temperature and
precipitation amount.

Table 3 show that only 8.5% of the households were
headed by females and this confirmsfindings [19] that Maasai
communities are patriarchal and women are less involved in
decision making, and are often relegated to taking care of the
children and other household activities. This is expected to
reduce the female headed household early access to climatic
information and early warning information and affect their
ability to respond early to extreme climatic events. Data on
household size shows that 91.5% of respondents had
household size of more than Five (5) people. Results showed
that 33% of the household heads had no formal education and
level of education affect the ability of pastoralist to adapt to
climate change. Lack of formal education affects the ability
of the household to understand and interpret climate
information for decision making [21]. Various findings have
101
shown that household size has a significant influence on the
vulnerability of the households to climate change and climate
extremes [22].
Smaller households are usually less susceptible to climate
extreme events such as drought. This is because food scarcity
is one of the main challenges during drought and the lesser
the household size, the easier it is to cope with scarcity of
food. The results also showed that other adaptive capacity
indicators such as marital status, access to extension agents,
herd size, livestock diversity and access to credit facilities
positively influenced vulnerability in the study area. These
results concur with the findings which similarly reported that
most of these variables affects household vulnerability to
climate change in the pastoralist communities [15, 21].

Vulnerability Analysis of Maasai pastoralist to climate change in Kajiado County
Table 4 shows the result of the factor score for the first
principal component analysis and its association with the
vulnerability variables. Principal Component Analysis was
run on the indicators listed in Table 2 to generate the factor
scores. The first principal component was used to generate
the factor scores (weight) because it explains 91% of the
102
Bobadoye Ayodotun Olufemi et al.: Assessing Vulnerability of Maasai Pastoralist in Kenya to Climate Change and Variability
variations. Vulnerability index was computed based on the
definition of vulnerability in equation (2) which defines
vulnerability as a net effect of adaptive capacity minus
exposure and sensitivity. The indicators of adaptive capacity
which were positively associated with the first principal
component analysis and the indicator of sensitivity and
exposure, which were negatives associated with the first
principal component analysis were used to calculate the
vulnerability index in the study. This is because the
vulnerability equations shows that increase in adaptive
capacity contributes to reduction in vulnerability, while
increase in exposure and sensitivity increases vulnerability.
The variables with higher factor scores have higher influence
on vulnerability in the study area. The vulnerability of
households in the study area was classified based on the
different communities in the study area using the
vulnerability index.
The result of vulnerability index of communities in
Kajiado east is presented in table 5. This study calculated
vulnerability index for 305 households in 56 Maasai
communities in the five administrative wards in Kajiado east
sub-County. The vulnerability index of the communities was
determined by calculating the average vulnerability index for
households in each community. The results shows that
Ilpolosat, Oloosirikon, Lenihani, Konza and Oloshaiki were
the most vulnerable communities having the highest negative
vulnerability index value of -2.31, -2.22, 02.05, -1.81 and 1.53 respectively. The least vulnerable communities with the
highest positive vulnerability index values were Kekayaya,
Kepiro, Omoyi, Esilanke, Kisaju and Olmerui with values of
4.02, 3.47, 2.81, 2.23, 2.16 and 2.15 respectively. The
vulnerability index of communities varied between 4.02 to 2.31. The result shows high disparity in the vulnerability of
communities in Kajido east. It concur with the findings
which reported that land sub division and sales among the
Maasai in Kajiado has increased the standard of living of few
Maasai while most are left highly vulnerable and unable to
practices their pastoralist system [20]. Increase in dry spell
and drought over the last few decades coupled with
restriction in animal movement have also increased
vulnerability of Maasai pastoralist to climate change and
variability [16, 21].

Vulnerability maps of households and communities in Kajiado East sub County
Maps have the advantage of presenting data in an easily assessable, readily visible and eye catching manner. Mapping
vulnerabilities to climate change is a key planning tool for government and policy makers in resources allocation and
adaptation planning. There is the urgent need in Kenya for availability of information especially at the local levels where
intervention are needed for establishing early warning systems, disaster risk response and capacity building.
Figure 2. Map showing the level of vulnerability of households in Kajiado East to climate change and variability.

Bobadoye Ayodotun Olufemi et al.: Assessing Vulnerability of Maasai Pastoralist in Kenya to Climate Change and Variability
Figure 2 shows the vulnerability map of households in
Kajiado east sub-County. The map shows that households in
most communities in Kajiado east are moderately vulnerable to
climate change and variability. The map also revealed a high
level of variation in the vulnerability of some households
within the same community. This shows that although
communities are exposed to the same climatic factors, the
adaptive capacity of the household has a significant effect on
its vulnerability. Individual households within the community
vary in socio-economic characteristics such as level of
education, wealth, access to credit and political power; which
are responsible for variation in vulnerability levels [9, 11].
Mapping household vulnerability is important in identifying
vulnerable household within a community and also
understanding vulnerability pattern of household in the
community. However, mapping vulnerability at the
community level provides information for policy makers and
decision makers to take informed decisions that will enhance
resilience of vulnerable communities.
Figure 3 shows the vulnerability map of communities in
Kajiado east. The map categorized communities into highly
vulnerable, moderately vulnerable and vulnerable
communities based on their vulnerability index. The maps
revealed that although most communities in Kaputie North
ward are moderately vulnerable; Maasai communities in
Iloposat, Lenihani, Oloshaiki and Olturoto are highly
vulnerable to climate change and variation. Kitengela ward
has the highest number of Maasai communities that are less
vulnerable; this might be due to the availability of basic
amenities such as good roads, electricity and hospitals.
Maasai communities that are highly vulnerable to climate
change and variability in Sholinke ward are communities
living in Oloosirikon and Korrompoi. The other Maasai
communities in Sholinke are moderately vulnerable to
climate change and variability. The map shows that
communities in Mbilin and Koonza of Imaroro ward are also
highly vulnerable to climate change and variability. In
Kenyawa-Poka ward, most communities are moderately
vulnerable to climate change and variability, however, the
map shows that communities in Noompai are highly
vulnerable while those in Esilanke are less vulnerable to
climate change and variability.
Figure 3. Map showing the level of vulnerability of communities in Kajiado East to climate change and variability.
International Journal of Agricultural and Environmental Sciences 2018; 3(6): 97-107
The maps further revealed that Kaputiei North sub
county has the highest number of highly vulnerable
households, followed by Oloosirkron/Shilonke, Imaroro and
Kitengela has almost the same number of household that are
highly vulnerable while Kenyawa-Poka has the least
number of households that are highly vulnerable. The
household that are highly vulnerable are unable to cope
with the adverse effect of climate change and variability
and needs immediate external assistance in terms of relief
to survive. Previous studies in ASALs of Kenya reported
that it is becoming difficult for households to recover from
changing and inconsistent weather conditions affecting the
pastoralist livelihood [4, 19, 23]. The result is also
consistent with the findings conducted in similar ecosystem
in Kenya [20, 21].
Findings from this study shows an urgent need for
evidence based policies and plans to improve the adaptive
capacity of Maasai pastoralist through provision of basic
amenities and also well structured early warning and disaster
response systems to reduce their vulnerability to climate
105
change and variability.
Variables influencing household vulnerability in the study
area.
The result of the ordered logistic regression model for the
variables influencing the vulnerability of household is
presented in Table 6. A total of nine variables have significant
influence (at 5% and 10% levels of significance) on
vulnerability to climate change in the study area. The result
shows that gender of household head, years of experience in
the area, educational level, visit by extension agents, herd
size, livestock diversity, land size and livestock mobility has
significant influence on vulnerability in the study area.
The Maasai communities are typically patriarchal and
female headed households, households that access to
extension agents and those with low level of education are
significantly vulnerable to climate change. This is because
such households either lack access to information for early
decision making during extreme climatic events or lack the
economic capacity to act on decisions during extreme
conditions.

Several studies conducted in pastoral communities in
Eastern Africa reported that female headed household are
usually not empowered enough to take decisions during
extreme climatic events such as drought and are frequently
without access to credit services and adequate capital assets.
They are also not able to own large herds to manage
household’s daily requirements. This shows the need to
specifically target pastoralist women in climate change
adaptation planning in arid and semi-arid lands of Kenya [15,
22, 27]. This study also concurs with findings which reported
the significant influence of level of education on
vulnerability in similar ecosystem [6].
The significant influence of herd size, livestock diversity,
access to credit, land size and livestock mobility is also
reported in this study. These factors enhance the ability of
households to cope during extreme climatic events and
reduce their vulnerability to climate change and its extremes.
This agrees with studies that also reported some of these

factors as key determinant of household vulnerability to
climate variability and change in rural communities [10]. The
result is also consistent with previous studies conducted in
similar ecosystem [15, 22].
4. Conclusion
This study used indicators developed jointly by the
researcher and the Maasai communities to analyze household
vulnerability of Maasai communities in Kajiado east.
Categorization of vulnerability levels using maps is useful for
government both at the National and County level for
efficient resource allocation to the wards. Human adaptive
response to climate change occurs at the local and household
level where the climate variability is experienced. It is
therefore crucial to understand vulnerability at the household
level for timely intervention and also for development of
evidence based policies that will lead to effective adaptation
programmes for long term resilience.
The vulnerability map shows that households in Kitengela
ward which is the most developed ward in terms of access to
basic amenities is the least vulnerable ward in Kajiado East.
Result also shows that indicators such as gender of household
head, level of education, access to credit facilities, access to
extension services and herd’s mobility significantly affects
vulnerability of Maasai pastoralist to climate change and its
effect. There is a direct link between level of infrastructural
development and level of vulnerability in the study area. The
study shows that areas that have access to basic amenities
such as schools, health centers and water are less vulnerable
to climatic extremes. It is therefore necessary for government
at all levels to develop policies and programmes that will
address the huge infrastructural deficit in Kajiadocounty, as
this will not only reduce vulnerability to climate extremes.
Provision of amenities such as good roads, health centers,
experienced extension workers are no regret options that can
increase resilience of pastoralist toclimate change and
variability. It will also reduce the huge poverty level which
currently stands at about 50% [12]. The study concludes that
there is disparity in the vulnerability levels of households
within communities and also among wards in Kajiado east.
Resilience intervention should therefore be specific, targeting
wards within the Counties and also particular households
within the communities. Interventions such as women
empowerment, access to extension agents, provision of basic
infrastructures such as electricity, water, and good roads, free
herd mobility and access to credit facilities will increase
resilience of Maasai pastoralist in Kajiado East to the effect
of climate change and variability.
suggests the following areas for future research:
1 The impact of land fragmentation and privatization on
vulnerability of pastoralists in Kajaido County
2 The impact of rainfall variability on vegetation
dynamics in pastoral lands. This includes analysing the
linkages between rainfall and normalized difference
vegetation index (NDVI) in Kajaido County
