Ahmedabad's tree cover down to 24% from 46% in two decades: Study

By Rajiv Shah
A recent study, sponsored by the prestigious Indian Institute of Science (IISc), Bangaluru, has said that Ahmedabad's tree cover fell from 46% to 24% over the last 20 years, while the city's built-up area up increased by 132%. It predicts, by 2030, the vegetation cover will go down to 3% of Ahmedabad's area.
The study, which covers three other cities, Kolkata, Bhopal and Hyderabad, has used satellite-borne sensors, comparing images over decades and modeled past and future growth to reveal the rate of urbanisation in the four Indian cities.
The study says, Kolkata's tree cover fell from 23.4% to 7.3% over 20 years, while its built-up area went up by 190%; by 2030, its vegetation cover will be down to 3.37%. Bhopal's tree cover fell from 66% to 22% over the last 22 years, and by 2018, it will be down to 11% of the city's area. And Hyderabad's tree cover fell from 2.71% to 1.66% over 20 years, and by 2024, it will be 1.84% of city's area.

Revealing contents of the study, Deepa Padmanaban of indiaspend.com said, "The study has been carried out by Prof TV Ramchandran and his team at the Energy & Wetlands Research Group, Centre for Ecological Sciences, by analysing agents of change and drivers of growth, such as road networks, railway stations, bus stops, educational institutions and industries; defence establishments, protected regions, such as reserve forests, valley zones and parks."
"The researchers classifies land use into four groups: Urban or built-up, which includes residential and industrial areas, paved surfaces and mixed pixels with built-up area, meaning built-up areas which contain areas from any of the other three categories water, which includes tanks, lakes, reservoirs, and drainages; vegetation, which includes forests and plantations; and others, including rocks, quarry pits, open ground at building sites, unpaved roads, cropland, plant nurseries and bare land", she added.

The study says, the population of Kolkata is now 14.1 million, making it India's third-largest city. While its urban built-up area increased 190% between 1990 and 2010, in 1990, just about 2.2% of land was built up; in 2010, 8.6%, which is predicted to rise to 51.27% by 2030.
As for Hyderabad, with a population of 7.74 million in 2011, it is poised to be a mega city with 10 million people in 2014. Its urban built-up area rose 400% between 1999 and 2009. In 1999, 2.55% of land was built up; in 2009, 13.55%, which is predicted to rise to 51.27% by 2030.
Ahmedabad had a population of 5.5 million in 2011. It is the sixth largest city of India. While between 1990 and 2010 its built-up area rose by 132%, in 1990, 7.03% of land was built-up, which in 2010 reached 16.34%, and is predicted to rise to 38.3% in 2024.

Bhopal, which is one of India's greenest cities, with a population with 1.6 million people, is better off than other cities even today, "but the concretising trend is clear", says Padmanaban, adding, "In 1992, 66% of the city was covered with vegetation (in 1977, it was 92%); that is down to 21% and falling."
"India's fastest growing city has traditionally been Bangalore. There are no recent estimates for its concretisation, but in 2012, Ramachandran and his group found a 584% growth in built-up area over the preceding four decades, with vegetation declining 66% and water bodies 74%", Padmanaban says, quoting the study.
"The highest increase in urban built-up area in Bangalore was evident between 1973 and 1992 -- 342.83%. Decadal increases since, between 1992 and 2010, have averaged about 100%: 129.56% from 1992 to 1999; 106.7% from 1999 to 2002; 114.51% from 2002 to 2006; and 126.19% from 2006 to 2010", she said.
"Bangalore's population rose from 6.5 million in 2001 to 9.6 million in 2011, a growth of 46.68 % over a decade; population density increased from 10,732 persons per square kilometre in 2001 to 13,392 persons per square kilometre in 2011", she added.

A comrade in culture and controversy: Yao Wenyuan’s revolutionary legacy

By Harsh Thakor* This year marks two important anniversaries in Chinese revolutionary history—the 20th death anniversary of Yao Wenyuan, and the 50th anniversary of his seminal essay "On the Social Basis of the Lin Biao Anti-Party Clique".

History, culture and literature of Fatehpur, UP, from where Maulana Hasrat Mohani hailed

By Vidya Bhushan Rawat* Maulana Hasrat Mohani was a member of the Constituent Assembly and an extremely important leader of our freedom movement.

New RTI draft rules inspired by citizen-unfriendly, overtly bureaucratic approach

By Venkatesh Nayak* The Department of Personnel and Training , Government of India has invited comments on a new set of Draft Rules (available in English only) to implement The Right to Information Act, 2005 . The RTI Rules were last amended in 2012 after a long period of consultation with various stakeholders. The Government’s move to put the draft RTI Rules out for people’s comments and suggestions for change is a welcome continuation of the tradition of public consultation. Positive aspects of the Draft RTI Rules While 60-65% of the Draft RTI Rules repeat the content of the 2012 RTI Rules, some new aspects deserve appreciation as they clarify the manner of implementation of key provisions of the RTI Act. These are: Provisions for dealing with non-compliance of the orders and directives of the Central Information Commission (CIC) by public authorities- this was missing in the 2012 RTI Rules. Non-compliance is increasingly becoming a major problem- two of my non-compliance cases are...

What Epstein Files reveal about power, privilege and a system that protects abuse

By Bhabani Shankar Nayak* The Jeffrey Epstein scandal is not merely the story of an individual offender or an isolated circle of accomplices. The material emerging from the Epstein files points to structural conditions that allow abuse to flourish when combined with power, privilege and wealth. Rather than a personal aberration, the case illustrates how systems can create environments in which exploitation becomes easier to conceal and harder to challenge.

Celebrating 125 yr old legacy of healthcare work of missionaries

Vilas Shende, director, Mure Memorial Hospital By Moin Qazi* Central India has been one of the most fertile belts for several unique experiments undertaken by missionaries in the field of education and healthcare. The result is a network of several well-known schools, colleges and hospitals that have woven themselves into the social landscape of the region. They have also become a byword for quality and affordable services delivered to all sections of the society. These institutions are characterised by committed and compassionate staff driven by the selfless pursuit of improving the well-being of society. This is the reason why the region has nursed and nurtured so many eminent people who occupy high positions in varied fields across the country as well as beyond. One of the fruits of this legacy is a more than century old iconic hospital that nestles in the heart of Nagpur city. Named as Mure Memorial Hospital after a British warrior who lost his life in a war while defending his cou...

Elimination of top Maoist leader alters the balance in India’s longest insurgency

By Harsh Thakor* Madvi Hidma ’s killing in an encounter in the Maredmilli forests along the Chhattisgarh–Andhra Pradesh border recently marks a significant moment for the CPI (Maoist). His wife, Rajakka, and four others were also killed. Hidma, long considered one of the organisation’s most influential field commanders, had been associated with the insurgency in Bastar for nearly three decades. He was one of the few tribal cadres to rise from a child recruit to the upper decision-making levels of the banned Maoist party.
