Environmental sustainability manages risks related to the natural environment and natural sources like energy and water. This issue is further amplified in Urban areas as the global urban population outstripped the rural population. The rising water demands caused by urbanization, population expansion has stressed ground water resources in Karachi. Water level is constantly declining, and climate change has further aggravated this condition. Multiscale Landscape based ground water recharge can be a sustainable solution to amplify natural infiltration process that could be a resultant for ground water replenishment in Karachi. Malir river basin is selected for the study as basin hydrology is impacted and degraded; several agricultural activities are also taking place in this area and are affected due to scarce water resources, salinity, urbanization, soil degradation and specially the construction activities along its bank and the agricultural land surrounding it is exceedingly replaced by the real estate development. This research aims to identify the development strategies for landscape-based water recharge in the Malir River basin and focusing on multiscale sustainable approaches to increase groundwater replenishment, alleviate surface runoff to water sources, moreover, to overcome challenges in groundwater recharge. Mapping is done to identify potential zones in river basin based on topography, land use and hydrological uses, designing and implementing the green infrastructure Furthermore, this paper will suggest policies and recommendation integrated as part of water resource management strategy and urban planning, enhance landscape water recharge, and discuss aquifer recharge techniques for the Malir river basin.
