Hyderabad district occupies an area of approximately square kilometers. According to the census the population of this district was 3,, Hyderabad is known as the City of Pearls, as it had once flourished as a global center for trade of rare diamonds, emeralds as well as natural pearls. Home About District. Print Share Facebook Twitter. Geography: Area: Sq Km. Altitude: Meters. Climate: Tropical Wet and Dry. Summer: Max 40 C and Min 22 C. The capital Bhagyanagar was named after a royal beloved Bhagyamati, who later as the wife of Quli Qutub Shah became Hyder Mahal and thus was born Hyderabad.
The Qutb Shahi dynasty founded the Kingdom of Golconda, one of the five kingdoms that emerged after the break up of the Bahamani Kingdom. The Qutb Shahis ruled the Deccan for almost years. All the seven rulers were patrons of learning and were great builders. They contributed to the growth and development of Indo-Persian and Indo-Islamic literature and culture in Hyderabad. During the Qutb Shahi reign Golconda became one of the leading markets in the world of diamonds, pearls, steel for arms and also printed fabric.
With the conquest of the Deccan and the South, Aurangzeb succeeded in expanding the Mughal Empire to cover the entire sub-continent. On the other hand, during the winter months when temperatures and inversion heights are low, there is a greater impact of emissions on pollution concentrations.
Low temperatures also affect behaviour through the need for space and water heating — which in turn has increases emissions. In Phase 1, base year for all the calculations was In Phase 2, all the calculations are updated for year We customized the SIM-air family of tools to fit the base information collated from disparate sources. Apart from the official reports, resource material ranges from GIS databases of land use, land cover, roads and rail lines, water bodies, built up area represented in the adjacent figure , commercial activities such as hotels, hospitals, kiosks, restaurants, malls, cinema complexes, traffic intersections, worship points, industrial hubs, and telecom towers , to population density and meteorology at the finest spatial resolution possible 1-km.
A detailed description of these resources is published as a journal article in , which also includes a summary of baselines and pollution analysis for 20 Indian cities. This emissions inventory is based on available local activity and fuel consumption estimates for the selected urban airshed represented in the grid above.
This information is collated from multiple agencies ranging from the central pollution control board, state pollution control board, census bureau, national sample survey office, ministry of road transport and highways, annual survey of industries, central electrical authority, ministry of heavy industries, and municipal waste management, and publications from academic and non-governmental institutions. For the road transport emissions inventory, besides the total number of vehicles and their usage information, we also utilized vehicle speed information to spatially and temporally allocate the estimated emissions to the respective grids.
This is a product of google maps services. For the city of Hyderabad, we extracted the speed information for representative routes across the city for multiple days. This data is summarized below for a quick look. However, these are included in the overall chemical transport modeling in the national scale simulations. We based the vehicle growth rate on the sales projection numbers; industrial growth on the gross domestic product of the state; domestic sector, construction activities, brick demand, diesel usage in the generator sets, and open waste burning on population growth rates and notes from the municipalities on plans to implement waste management programs.
We used these estimates to evaluate the trend in the total emissions and their likely impact on ambient PM2. The emissions inventory was then spatially segregated at a 0. The gridded PM 2.
