Attention to nature based solution in watershed conservation and management is increasing in the developing world as chemicals continue degrading agricultural land; garbage and urban sewage infrastructure are sediment clogged. The realization of significance of watersheds is fundamental for utilization that is sustainable where urban livelihoods recreation and economies are majorly dependent on the utilization of natural resources.Lake Ullal is characterized by surrounding population density that is high made up of urban population characterized by raw sewage disposal, garbage and flow of debris from construction. The catchment areas engage in agriculture characterized by use of pesticides and fertilizers that dissolve in the flowing water to the lake. These materials pose a serious threat to the watersheds.The high population density at the catchment has led to intensive agriculture that is characterized by pressure to yield more output to match the demand. There is a big gap between institutional and policy framework development at the high level and real implementation of proposals on the ground to combat soil erosion,land degradation and need to decrease the sediment load. The study mainly focused on the catchments of Ullal while assessing anthropogenic activities that have led to degradation of the lake. This provides an insight of nature based solution that can be adapted to conserve and manage the precious lake. The concept of Nature based Solution (NBS) provides adequate recommendation that can be adopted to salvage the lake for future generations
