The environment and forest minister of the Delhi government, Imran Hussain, on April 24, 2018, wrote letters to the Delhi Development Authority (DDA), the Public Works Department (PWD) and also the municipal corporations in the national capital, pointing out efforts to increase the green cover in the city. “Green cover can also be enhanced, by undertaking vertical gardening activities on buildings, flyovers, spaces and columns underneath the flyovers. This will help in neutralising the air pollution due to dust and vehicular pollution,” Hussain wrote in his letter.
In his letters to the DDA vice-chairperson, mayors of the three municipal corporations and the PWD minister, Hussain urged them to direct agencies and departments under their ambit, to undertake vertical plantation in a big way across Delhi. Vertical gardening involves growing plants on vertical surfaces of urban structures like flyover columns and buildings, with an integrated water irrigation system.
Last week, Lt Governor Anil Baijal, in a meeting, had directed the municipal corporations and the DDA to come up with vertical gardens on flyovers and irrigate them with non-potable water only. He had also stressed on developing green parks on vacant gram sabha lands, to achieve the goal of ‘Green Delhi’.
