    Being susceptible to climate change means being unable to cope with the adverse effects of climate change especially droughts and a likelihood of experiencing harm due to its occurrence. The study sought to evaluate the effects of exposure to Climate related shocks on the livelihoods of the smallholder farmers with the intent of formulating appropriate policies to enable them cope with its impacts. A descriptive survey research design was used. Stratified random sampling was employed to select 390 households. Two methods were used to analyse exposure. Firstly the fuzzy logic in assessing susceptibility to drought involving a selection of input variables, Fuzzification, inference modelling and defuzzification and secondly DrinC Model software. The results revealed that the final value of the negative consequences of drought was 0.35.The study also established a single index as 0.45 for exposure for the entire study period of 35 years for Kinakomba Ward .The study showed that exposure was statistically significant at (0.000066). The study further revealed that the periods between occurrence of extreme droughts were reducing and at the same time that droughts were moving from being severe to being extreme within shorter periods of time leaving smallholder farmers who depend on rain fed agriculture with high exposures and risks as well as experiencing longer hunger periods with severe implications on their food and nutritional security for the vast populations in the study area. The Study concluded that the exposure to drought of the smallholder farmers in Kinakomba Ward is significantly related to their farming livelihood systems. This study recommends that the County Government in partnership with the National Government and other stakeholders develop a comprehensive disaster risk management framework to address the drought hazards and undertake mitigation and adaptation measures by equipping the smallholder farmers with knowledge on how to cope with the cyclic and vicious droughts’ impacts that have led to serious irreversible harm to humans and livestock in the area.

    Understanding the future of smallholder farmers of Kinakomba Ward in Tana River is critical to the design and development of policies. One of the major concerns is establishing how sensitive these farmers are to climate change shocks. This study sought to determine sensitivity index of smallholder farmers that rely on rainfed agriculture and nonfarming activities to climate change related shocks with the intent of formulating appropriate programmes and policies. A descriptive survey research design was used. Stratified random sampling was employed to select 390 households. The qualitative and quantitative data collected using questionnaires was analysed by use of metric of sensitivity and chi-square goodness of fit test. The study revealed that smallholder farmers who relied on farming activity alone had a sensitivity of 43.17% to climate change related shocks while those who rely on non-farming activities had a sensitivity of 36.40%. When the households engage in both farming and non-farming, the sensitivity will increase by 21.20% due to the interactions between the two activities. Although the sensitivity percentage for the farmers who engaged in the two activities is low, sensitivity was statistically significant (P=0.00038).  Further findings showed that the ratio of farming to nonfarming was 0.58 and those households dependent on farming and engaged in nonfarming was 0.45 and when they engage in both activities at the same time, they were more sensitive at 0.942. Despite the significance sensitivity to climate change related shocks, farming sector was ranked as more important (81.5%) than other livelihood activities. The study concluded that sensitivity of the smallholder farmers to climate change related shocks had a significant influence on their livelihoods. The County Government in partnership with stakeholders develops interventions of adaptation options and empowerment of farmers with skills in diversification of livelihoods options.

    According to IPCC (2014) Adaptive capacity is the ability of systems, institutions, humans and other organisms to adjust to potential damage, take advantage of opportunities and respond to consequences arising. In a climate change context it relates to inter-relationship of social, political, economic, technological and institutional factors operating at a variety of scales Vincent, Katharine (2007) some genetic while others exposure specific. This study analyzed the adaptive capacity to climate related shocks of 390 farming households in Kinakomba Ward. The objective was: To determine the adaptive capacity index of the smallholder farmers in Kinakomba Ward. The index included five indicators of human resources, physical resources, financial resources, information and livelihoods diversity (Eakin and Bojorquez-Tapia 2008). The researcher used two methods to analyse adaptive capacity: Firstly an interview with 390 farming households to gather data on farming and household characteristics and Natural resources availability and secondly a panel of 15 Key Informants provided ratings of indicators of adaptive capacity using analytic hierarchy process (AHP). Using the Analytic Hierarchy Process (AHP) the results indicated that Livelihoods Diversity had the highest adaptive capacity score at 0.3 while the lowest adaptive capacity for Criterion was information at 0.12. Meaning that Livelihoods diversity was 3 times more preferred than information. The panel of key informants gave this alternative the highest weight and so this was the single adaptive capacity for Kinakomba ward. The results further revealed that occupational multiplicity had the highest score at 0.21 the panel of the key informants gave this indicator a high rating thus making it have the highest adaptive capacity while the lowest was given to infrastructure at 0.03, meaning occupational multiplicity at 0.21was 6 times more preferred to infrastructure at 0.03. The study concluded that When the Number of livelihoods sources are many and when the number of members in the household are also having different sources of livelihoods, then that household has a high adaptive capacity. Consequently when all the members of the households are adults and each has a job then the adaptive capacity of that household is high while a high dependency ratio leads to low adaptive capacity. The study recommended that the County and National governments and stakeholders to employ measures to adapt to climate change and variability.

    According to IPCC, (2007) Vulnerability is the degree to which a system is susceptible to, and unable to cope with, adverse effects of climate change, including climate variability and extremes. It is a function of exposure, sensitivity, and adaptive capacity (Marshall et al. 2010; Wongbusarakum and Loper 2011, Mucke 2012). The study sought to determine the vulnerability to climate related shocks among smallholder farmers in Kinakomba Ward. The main purpose of the study was to assess the extent to which, exposure, sensitivity and adaptive capacity contributed to the vulnerability of the smallholder farmers on their livelihoods. The study was carried out in Kinakomba ward in Tana River County, Kenya. A descriptive survey research design was used. Stratified random sampling was employed to select 390 out of a population of 3,908 households. Data was collected using questionnaires and Focus Group Discussions. Descriptive statistics, metric of sensitivity, composite index was used to analyse sensitivity. Two methods were used to analyse exposure. Firstly the fuzzy logic in assessing susceptibility to drought involving a selection of input variables, Fuzzification, inference modelling and defuzzification and secondly DrinC Model software. The researcher used two methods to analyse adaptive capacity namely the interview with 390 farming households to gather data on farming and household characteristics and natural resources availability and secondly a panel of 15 Key Informants provided ratings of indicators of adaptive capacity using analytic hierarchy process (AHP). To understand the interaction of these variables this study Analysed a quantitative Vulnerability score by using an equation which  combined three contributing indices of exposure, sensitivity and adaptive capacity each normalized to 0–1 Scale (Adger and Vincent, 2005;Allison et al. 2009), the vulnerability score was obtained by adding exposure to sensitivity and subtracting the adaptive capacity. The key results from the study showed that exposure (p=0.000066) and sensitivity (P=0.00038) had a significant effect on livelihoods. These factors were also found to have a negative influence on livelihoods in the area. Further statistical findings showed that as adaptive capacity increased vulnerability decreased while when sensitivity increased vulnerability increased at the same time. The study concluded that these two dimensions of vulnerability could be modified by policy and development. The study also concluded that exposure contributed more than sensitivity and adaptive capacity to the cumulative vulnerability. The study recommended that the County and National governments and stakeholders to employ measures to adapt to climate change and variability. This study also recommended that the Government in partnership with other stakeholders develop a comprehensive disaster risk management framework to address the drought hazards and undertake mitigation and adaptation measures by equipping the smallholder farmers with knowledge on how to cope with the cyclic and vicious droughts’ impacts that have led to serious irreversible harm to humans and livestock in the area. Also that the Government in partnership with stakeholders develops interventions of adaptation options and empowerment of farmers with skills in diversification of livelihoods options.

    The Dandora Estate Sewage Treatment Works (DESTW) in Ruai, Nairobi County discharges approximately 80,000 m3/day of treated wastewater (TWW) into the Nairobi River without any planned option for use. There is also no policy guideline for use of TWW in Kenya. Yet, some people still use it directly or indirectly for their various livelihoods and in unsustainable ways (unplanned, unmanaged and unregulated). This could result in a number of risks, including public health, agronomic and environmental risks. This study investigated factors influencing the adoption of the TWW use among the communities in seven estates (Sewage/IDP, Gituamba, Kamunyonge, Katworo, Bondeni, Dan Bull and By-pass) that are close to the DESTW, despite the prevailing scenario. Cross-sectional survey design was adopted in the study where semi-structured questionnaires were used to collect data from 360 households who were selected using simple random sampling from the seven estates/strata. Raw data were analysed with the help of Statistical Package for Social Sciences [version 20] software for both descriptive statistics (percentages and frequencies) and inferential statistics (Odds Ratio, and Wald χ2) for the prediction of adoption of TWW (dependent variable) using the independent variables. A multivariate logistic regression model identified gender (Wald χ2 (1) = 5.31, p = .021), main occupation in general (Wald χ2 (7) = 21.06, p =.004), farming [Wald χ2 (1) =5.31, p =.021], dependency on wastewater (Wald χ2 (1) = 40.59, p ˂ .000) and knowledge of organization regulating use of TWW (Wald χ2 (2) = 6.76, p =.034) as statistically significant predictors of adoption of TWW use in Ruai. In the absence of a policy guideline for use of TWW in Kenya, the findings of the study provide requisite baseline data useful in formulating an appropriate policy and regulations for wastewater reuse schemes.

    The study examined the current status in quality of the treated wastewater (TWW) discharged at Dandora Estate Sewage Treatment Works (DESTW) in Ruai with a view to assessing its reuse potential and conformity to the national standards recommended for safe use. The DESTW discharges approximately 80,000m3/day of TWW through its three outlets into the adjacent Nairobi River without any planned use option. However, some people use it directly or indirectly for their livelihoods oblivious of its quality status, putting at risk their own health, public health and the environment. Understandably, with freshwater becoming increasingly scarce, thus limiting livelihood options, water planners and users are forced to reconsider other water resources such as wastewater which can be used both economically and effectively. Samples of TWW were collected from the three outlets (sampling sites) at DESTW, prepared and analysed for heavy metals [lead (Pb), zinc (Zn), copper (Cu), cadmium (Cd), chromium (Cr), manganese (Mn), nickel (Ni) and iron (Fe)]; macronutrients [nitrogen (N) as nitrate, phosphorous (P) as phosphate and potassium (K)] and environmental characteristics [microbes; faecal coliforms (FC) and total coliforms (TC), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total solid (TS), pH and chlorides]. Raw data were analysed with the help of Statistical Package for Social Sciences [SPSS] software version 20 for both descriptive statistics (means and standard deviations) and inferential statistics (ANOVA’s F and post hoc procedures by Tukey and Games-Howell test where applicable & Kruskal-Wallis H test. All inferential statistical tests were conducted at a 0.05 level of significance. Results showed that the content of Cd, Cr, Fe, Mn, phosphate, TS, chlorides, and pH were lower than their safe limits for reuse but that of lead, BOD, COD, nitrates and TC exceeded the recommended threshold limits. Results of one-way ANOVA performed on the data suggested that the levels of all the measured parameters of the study except Fe, Pb, pH, BOD and FC varied significantly among the three sites. Overall, the results show that the TWW is not entirely safe for use in its current quality state. There is need for an improved optimal wastewater treatment configuration at DESTW aimed at rendering suitable effluent for reuse schemes in Ruai.
