Yelahanka, located in the northern part of Bengaluru, is known for its blend of urban development and natural features. The environment of Yelahanka is strongly influenced by its lakes and local weather conditions, which play an important role in supporting biodiversity, groundwater recharge, and the quality of life for residents.
One of the most significant environmental features of Yelahanka is its network of lakes. Lakes such as Yelahanka Lake, Allalasandra Lake, Puttenahalli Lake, and Jakkur Lake are part of the traditional lake system of Bengaluru. These lakes were originally built to store rainwater, prevent flooding, and support agriculture. Even today, they serve as important ecological zones. They help recharge groundwater, which is essential for domestic use, especially during dry seasons.
The lakes of Yelahanka support a variety of plant and animal life. Aquatic plants, fish, frogs, and insects form the base of the ecosystem, while birds such as egrets, herons, kingfishers, and migratory birds are commonly seen around these water bodies. Trees and wetland plants around the lakes help in reducing air pollution and provide shade, making the surroundings cooler. Lakes also act as natural filters by trapping dust and pollutants, thus improving the local environment.
However, rapid urbanization has put pressure on Yelahanka’s lakes. Encroachment, sewage inflow, plastic waste, and construction activities have led to pollution and reduction in water quality in some lakes. Community participation, lake rejuvenation projects, and awareness programs are essential to protect and restore these valuable water bodies. Efforts by local residents and environmental groups have already shown positive results in some areas through cleaning drives and proper maintenance.
The weather of Yelahanka is another important environmental factor. Due to its location on the Deccan Plateau and its elevation, Yelahanka generally enjoys a moderate climate. Summers are warm but not extreme, with temperatures usually ranging between 25°C and 35°C. The presence of lakes and green spaces helps reduce the heat by cooling the surrounding air.
Monsoon season, from June to September, brings most of the annual rainfall. This rainfall is crucial for filling lakes and replenishing groundwater. Proper lake management helps prevent waterlogging and flooding during heavy rains. Winters, from November to February, are mild and pleasant, with cooler temperatures and lower humidity, making it a comfortable season for outdoor activities.
In conclusion, the environment of Yelahanka is closely linked to its lakes and weather. The lakes play a vital role in maintaining ecological balance, supporting wildlife, and regulating climate, while the moderate weather enhances livability. Protecting lakes, increasing green cover, and adopting sustainable practices are necessary to preserve Yelahanka’s environment for future generations
