Living labs and community engagement for the restoration and sustainability of urban lakes
We investigated the water quality of Venkateshpura Lake by using water and sediment samples. The lake is located within Venkateshpura and Sampigehalli villages in the north taluk of Bengaluru. We found that the lake is in a eutrophic state based on the parameters chlorophyll-a, secchi depth and total phosphorus. The lake has a high concentration of nutrients, which support the growth of plants and leads to eutrophication. The dissolved oxygen (DO) levels in the lake varies throughout the day and drops critically during the night, which results in the death of aquatic species. Sediment analysis shows that internal processes contribute to the nutrient loads in the lake.
Recognising the significance of nature-based solutions, we propose exploring interventions such as floating islands to tackle the nutrient contribution from lake sediments. By adopting a living lab concept, we aim to create an engaging platform for stakeholders and school children to enhance their understanding of the natural environment. To achieve this, we plan to organise training programmes aligned with the school curriculum. These programmes will equip students with the knowledge of fundamental water quality parameters and enable them to apply these concepts in practical situations. By fostering these connections between education and real-world application, we hope to cultivate an environmentally conscious generation actively involved in preserving our water resources.
