legislation requires 15% of residential layouts to be retained for public open space, and an additional 10% for civic amenities. However, within the area of the BBMP one study estimated that only 8.4% of the urban area is parkland whilst the 2003 Bangalore Master Plan allocated only 2.01 sq m of green space per citizen, 6.99 sq m less than the minimum recommendation of the World Health Organisation. By way of comparison, the 'Urban Green Guidelines, 2014' issued by the Government of India calculates the average green space for cities worldwide at 18.6% and Bangalore's area of green space at less than 5%. Bangalore compares unfavourably with New Delhi, which has retained 20% of its urban area as public open space. It also demonstrates a significant deterioration since the 1960, when open space represented 17.2% of the total area. Tree planting The BBMP's responsibilities include planting and maintaining street trees. The BBMP has embarked upon numerous tree planting schemes over many decades and with varying levels of success. The most notable period of planting is held to be the period of 1982 and 1987 when Chief Minister R Gundu Rao appointed forest officer S G Neginahal to green the streets of Bangalore with more than 15 lakh trees. His systematic plantation program involved the establishment of new nurseries, the installation of tree guards, a five-year monitoring program and the replacement of any failed plantings. The reported success rate was 97% and most of the mature trees along Bangalore's major avenues date to this era. More recently the BBMP has reported that between 2007 and 2013 more than 10 lakh trees have been planted with a survival rate of 64.5%. These numbers have been contested by civic agencies and citizen groups as inaccurate. The Bangalore-based Environmental Support Group did a ground survey to calculate a survival rate of 20 – 25%, assuming the trees were even planted at all whilst urban conservationist Vijay Nishanth estimates a survival rate of 10%. The BBMP places responsibility for this with the lack experience of their contractors. Contractors in turn blame the BBMP for failure to release funds and allocating sapling locations in places with no water or suitable growing conditions. In 2017 the High Court of Karnataka directed the BBMP to plant an additional 10 lakh street trees and to form greening committees comprising activists and experts, and tree wardens. To comply with this
