“…Bangalore constitutes India's third largest city, with a population of close to 8.5 million. A rapid increase in population density over the past decade has resulted in substantial expansion of built area and a corresponding decrease in green space [26]. The city has witnessed a concomitant, slow conversion of many large-and moderate-sized single domestic gardens in the city into small-sized, shared apartment gardens with lower tree density and diversity [5], which may also indicate a decrease in the levels of biodiversity of other species, such as birds and insects.…”

Domestic gardens may play a vital role in supporting urban insect biodiversity, despite their small size. This paper assesses the abundance, diversity and distribution of insects in urban domestic gardens in the tropics, through a study in the rapidly expanding Indian city of Bangalore. Fifty domestic gardens were studied using a combination of light traps and pitfall traps. We recorded a large number of insects, 2,185 insects from 10 orders, of which ants, bugs, beetles and flies were the most common. We found 25 species of trees (from 160 individuals) and 117 species of herbs and shrubs in the 50 sampled domestic gardens. The number of insect orders encountered was significantly related to the number of tree and herb/shrub species. Garden management practices also influenced the abundance and richness of insect orders. Thus, greater numbers of insects were observed in gardens with a greater proportion of bare soil relative to grass area and with less intensive weeding practices. More insect orders were encountered in gardens with a composting pit. Insect numbers were significantly reduced in gardens subjected to pesticide application. Most residents avoided application of pesticides and herbicides, citing health concerns.

“…Using this information, all slums mentioned in the report were visited. Given the extremely dynamic nature of urban growth in Bangalore [19,25], we found some slums to have been legalized and converted to residential areas, and others to have been razed. Furthermore, we found a number of areas that were identified as slums, but were in reality village settlements that had been engulfed by the rapid growth of the city.…”

Abstract:Urban greenery provides ecosystem services that play an important role in the challenging context of urban deprivation and poverty. This study assesses the social importance of vegetation through empirical assessment of 44 urban slums in the rapidly developing southern city of Bangalore, India. Vegetation played a major role in supporting nutrition by its role in food consumption, and in promoting health through the planting of species with medicinal use. Trees in slums also formed nodes for social activities including conversing and playing, domestic activities such as cooking and washing dishes, and livelihood activities such as the manufacture of broomsticks and tyre repair. Innovative methods of gardening were widely adopted, with kitchen gardens found planted in plastic bags, paint cans, old kitchen utensils and buckets, indicating the importance given to planting in environments with limited finances. Short and narrow trunked trees with medium-sized canopies and high economic value, such as Pongamia, were preferred. A greater focus on greening in slums is needed, and can provide an invaluable, inexpensive and sustainable approach to improve lives in these congested, deprived environments.

“…The question that naturally follows is which of the two patterns is more sustainable for urban planning and development? Nagendra et al (2012) answered this question indirectly: they recorded the changes of vegetation for Bangalore City, located in southern India, by analyzing the satellite images during the period from 2000 to 2007. They found that in the core of Bangalore, the vegetation areas had been preserved because this area was owned by the British military.…”

Controversial Issues Relevant to Sustainable Urbanism: A Review of Global Urban Tendencies

Academic urban debates shrouded with paradox render the transition to sustainable urban development (SUD) vague and unclear. The premise of this study is that the elimination of the controversial points included in each issue, in addition to reconciliation among these issues, may propel SUD. Therefore, this study dialectically discusses five urban issues: urban form, urban growth, transportation, urban vegetation, and governance (social participation). These issues were chosen among ten issues reviewed in a previous study in order to highlight controversial aspects and how to overcome them. The study suggests that the sociocultural dimension is an overlooked aspect in urban issues, and this may be a major reason for the conflict among academics. Further, this study concludes that governance is a major coordinator that can remedy the controversial points related to urban problems. Transportation is the second mediation among urban form, growth, and vegetation. Therefore, greater concern with governance and transportation in any urban planning policy improves current and future sustainable developments.
