The study applied Climate Risk Informed Decision Analysis (CRIDA approach) to assess  impacts of climate and socio-economic changes on water supply system and develop  adaptation pathways for Nairobi. With a boundary condition of Thika-Chania Sub-  catchment as a source of supply and population growth as a socio-economic factor,  assessment of system performance was attained through time series analysis, stakeholder  engagement, development and calibration of hydrological model for period 1988-2013.  With climate projections adopted for 4 RCM's under RCP 4.5 and RCP 8.5, and demand  projections under low, medium and high scenarios for 30 years, stress testing was done on  the system model under Cases of no climate change and under climate change  considerations. Formulation and stress testing of the adaptation actions under different  climate and demand scenarios was done to establish their robustness, after which pathways  were developed for both cases using Adaptation Pathway Generator. Most promising and  acceptable pathways were established through evaluation based on robustness, social and  environmental acceptability, and implementation period using adaptation scorecard.  From the results, it was established that the impacts of climate and socio-economic factors  will affect the supply system by increased varied flows and increased demand due to  population growth. On the evaluation of system performance, revealed that it's at high risk  of failure due to socio-economic factors compared to climate change. Three most promising  and acceptable pathways for the projection period were identified as (1) awareness  campaigns, water metering, expansion & rehabilitation of treatment plant, and alternative  source of supply. (2) water restrictions, policy regulations, expansion & rehabilitation of  treatment plant, and alternative source of supply. (3) awareness campaigns, water metering,  NRW reduction, and recycling of backwash water.   0aClimatic changeszKenyazNairobi 0aEconomicszKenyazNairobixSociological aspects 0aWater resources developmentzKenyazNairobi1 aBabel, Mukand Singh,eChairperson1 aGersonius, Berry,eCo-chairperson1 aShrestha, Sangam,eExamination Committee1 aXue, Wenchao,eExamination committee2 aNetherlands Fellowship Programmes (NFP),eScholarship Donor2 aUNESCO-IHE,eScholarship Donor2 aAsian Institute of Technology Fellowship,eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
