If we take the case of a possibledrought scenario than the HubRiver source, a rain fed source is amajor rain fed water supply sourcefor Karachi serving a population of 5million. Livelihoods of significanthuman settlements based in ruralKarachi Goths are dependent onfarming mostly using ground water.Ground water table is already loweringand aquifers are threateneddue to human activities such assand extraction. No water conservation,waste water recycling or rainwater harvesting practices are beingpromoted in the city.There is shortage in energy and substantialenergy loss. Energy consumptionis increasing and noefforts ongoing to promote energyconservation. Due to rising populationdensity in inner city and increasedtraffic /congestion thelikelihoods of the Heat Island Effecttaking place is quite likely. In thecontext of a possible sea level rise,adverse biodiversity impacts onwetlands and tidal zones and possibleloss of flora and fauna can beanticipated. Mangroves that can actas a buffer against tidal flooding arealready being devastated.(Source: Climate Profile of Karachi, KW&SB Climate Change Adaptation Strategy,2012, Ujala Qadir, WSP)20
