Nature-Based Solutions for Water in the ...

A brief description of the case study from the semi-arid, western state of Rajasthan in India. The NBS comprises a unique lake system situated in and around the historic city of Udaipur. This lake system, connecting the urban and peri-urban spaces, represents an integrated nature-based solution (NBS) rooted in rainwater harvesting. This case study was performed with two main aims in mind: 1) to analyse the historical factors underlying the sustainability of the Udaipur Lake system – considered along the three dimensions of sustainability (environmental, social and economic); and 2) to identify the challenges that are increasingly threatening its sustainability in recent times. The ultimate purpose is to propose alternative polices and action-plans to remedy the situation and promote water sustainability in this semi-arid region.
