Bengaluru: The rampant proliferation of Conocarpus plants across Bengaluru has ignited significant concern among residents and environmentalists. Despite being banned in regions such as the UAE, Gujarat, and Telangana due to its detrimental environmental and health impacts, the plant has been extensively utilised by the Bruhat Bengaluru Mahanagara Palike (BBMP) and Bengaluru Development Authority (BDA).
Conocarpus, commonly referred to as the Dubai plant, is highly favoured by civic agencies for its low maintenance and rapid growth, making it an attractive option for quickly greening urban areas. Hundreds of these plants have been strategically placed along major thoroughfares, stretches of the Outer Ring Road, and central avenues within Bengaluru. Additionally, the BBMP and BDA have cultivated these plants extensively in their gardens and nurseries.
However, the plant’s rapid spread has raised alarms. Conocarpus is known to absorb substantial amounts of groundwater, leading to the depletion of local water resources. Moreover, it negatively affects air quality and poses significant risks to respiratory health. Environmental activists have voiced concerns over the plant’s adverse effects, pointing out that initial information about its impact was limited.
“Initially, there was limited information about the adverse effects of Conocarpus. But experts have highlighted that it absorbs more groundwater and affects respiratory health. Its seeds are large and facilitate widespread propagation,” an environmental activist stated.
Plant experts have also weighed in, urging immediate action. “Conocarpus, which is banned elsewhere due to its health risks and detrimental effects on insects, shouldn’t be cultivated here. Immediate action is needed to clear the existing plants and stop further planting,” a plant expert emphasized.
In response to these mounting concerns, a senior forest conservator from the BBMP acknowledged the issue. “Experts have brought the ill-effects of Conocarpus plants to our attention. While the plant is grown for its greening effects, we’ll discuss the issue with senior officials and take appropriate action,” he assured.
The situation underscores the need for a more informed approach to urban greening projects, balancing the benefits of rapid greenery with the long-term environmental and health implications. As Bengaluru continues to expand, the choice of plant species for urban landscaping must consider sustainable practices and the well-being of its residents. The controversy surrounding Conocarpus serves as a critical reminder of the complexities involved in urban environmental management.
