The city of Amaravati in the southern state of Andhra Pradesh, India, is being built with the goal of becoming one of the most sustainable cities in the world. It will feature a green space measuring 5.5 kilometers long and 1 kilometer wide, where the government complex, legislature, high court and secretariat buildings will be located.

The development of Amaravati began after it was made the capital of Andhra Pradesh in 2015. Hyderabad, which was previously the state's capital, was transferred to the new state of Telangana following a redrawing of state lines. The project is handled by Foster + Partners, the London-based firm founded by architect Norman Foster.

The area Amaravati will cover was previously only populated by 25 farming villages. The government convinced farmers to give up their uninhabited agricultural land in return for smaller plots with better infrastructure in order to gain land to build the city on.

Solar energy will power every building in Amaravati, while the transport system will include electric cars and water taxis. At least 60% of Amaravati will consist of green space or water. This is a rendering of the government complex.

The government complex will be a focal point in Amaravati. It will sit at the heart of the green spine -- which is inspired by New York City's Central Park.

Foster + Partners is responsible for other sustainability projects, such as Masdar City in the United Arab Emirates, which aims to be carbon neutral and zero-waste.

Amaravati is part of a growing movement to "radically improve the living standards for millions of people," according to Foster + Partners.

Amaravati's major roads will be completed by the end of 2018, while the overall infrastructure will be built by the end of next year, according to Andhra Pradesh officials.

Currently, the city has approximately 140,000 residents -- including the 110,000 people who lived in this area before Amaravati was announced. New developments, including a planned central business district, are expected to create 430,000 jobs, according to officials.

Amaravati's population is predicted to rise to 3.5 million in 35 years' time, officials say. The new arrivals will mostly come from India -- but there are hopes that people from all over the globe would move to the city.

Story highlights

Created in 2015, Amaravati aspires to become a sustainable city.

British architect Norman Foster's firm is responsible for its planning.

Experts say it will be difficult to assess its sustainable credentials until after completion.

CNN  — 

In south-east India, 217 square kilometers of farmland along the Krishna River are being transformed into a city billed as an urban utopia.

When complete, Amaravati will not only be the new capital of Andhra Pradesh state – developers hope it will also be one of the most sustainable cities in the world.

At its center will be a 5.5-kilometer-long and 1-kilometer-wide Central Park-inspired green spine, according to British architectural firm Foster + Partners, which is leading the project.

Solar panels on rooftops will power Amaravati’s buildings, while cycling routes, electric vehicles and water taxis will serve the transport network. An irrigation system will utilize recycled water, and shaded streets will encourage walking.

The estimated total cost of the project is $6.5 billion, according to the Andhra Pradesh authorities.

“Many traditional settlements in India were built around principles of sustainability, and we have taken inspiration from them in our design,” said Chris Bubb, senior partner at Foster + Partners.

Urban oasis

In 2014, the redefining of state boundaries transferred Andhra Pradesh’s then-capital, the tech powerhouse of Hyderabad, to the newly created neighboring region of Telangana.

Left without a capital, the Andhra Pradesh authorities decided to build a new city. They would name it Amaravati, after an ancient village about 10 kilometers away.

But first they would need land. In 2015, they asked farmers to participate in a “land pooling scheme.”

For every acre farmers handed over, they would receive 25% to 30% of it back in developed land, equipped with power, running water, and sewerage facilities. They were also offered benefits such as free healthcare and education, according to the authorities.

Initially some farmers resisted, but by January 2017 the government had secured most of the land it needed, said Sreedhar Cherukuri, commissioner of the Andhra Pradesh Capital Region Development Authority.

About 28,000 farmers collectively gave 138 square kilometers of land to the project.

The government complex, with a futuristic needle-like design, will sit in the heart of the green spine that runs through the city.

The existing infrastructure would be upgraded, rather than wiped out, and villages in Amaravati’s path would be built around, ensuring no one was displaced from their home.

Who will live in Amaravati?

The pace at which Amaravati has been planned and constructed had made it “one of the fastest greenfield projects to be undertaken,” according to Cherukuri.

If all goes well, major roads will be completed by the end of 2018, and the overall infrastructure by the end of 2019, and the main government buildings – built by Foster + Partners – will be mostly finished by 2021, according to the development team.

Over the past two years, 30,000 people have already moved to the city, including 12,000 government employees working at a temporary administrative building that was constructed at the end of 2016.

Two universities opened their doors in 2017 to 4,000 students – five more are in the works.

Hospitals, schools, banks, hotels, in the planned Central Business District are expected to create 430,000 jobs, while cultural and sporting facilities are also in the works.

When the city is complete, it is expected to attract talent from around India – “perhaps from all over the globe,” said Cherukuri.

Residential properties for 5,000 low-income households and 4,000 government employees and their families are being built. There will also be commercial housing for 1,200 families.

The city’s population is expected to hit to 3.5 million in 35 years’ time, according to officials.

Switzerland's largest city took the top spot in the Sustainability Index, scoring highly in the Planet and Profit categories. The city is working towards becoming a "2,000-watt society," with the aim of using 2,000 watts of energy per capita by 2050 -- a level globally recognized as "sustainable" energy use.

The city-state was the top-ranked location in Asia. The government has undertaken a number of initiatives to improve mobility and connectivity in anticipation of population growing from 5.6 million to more than 6 million by 2030, according to the report. It didn't score highly under the People category, however -- long working hours and high costs of living affected the scoring.

Frankfurt has various sustainability measures: all buildings in the city must be developed according to energy use standards, and certain materials -- such as PVC -- are banned in their construction. The "Frankfurt e-mobility 2025" initiative calls for the use of electric cars and other green transport options.

South Korea's capital was the only other Asian city in the top 10 of the index. Out of 100 cities selected, it ranked first under the People category. To achieve high scores in this category would require "low inequality," the report says. The "2030 Seoul Plan" promoted goals like "a people-centered city without discrimination" and "stable housing and easy transportation."

Germany scored well with three cities in the top 10. Munich has sustainability policies across sectors such as the environment, energy and urban planning. Its Olympic Park, built for the games in 1972, has undergone constant upgrades, and stands today as a functional facility as well as tourist attraction.

How sustainable is a new city?

At least 60% of the city will be covered by green space and water, according to Foster + Partners.

Nirmal Kishnani, associate professor at the National University of Singapore’s School of Design and Environment, who is writing a book about sustainability in Asia, praised the city’s emphasis on nature and its focus on water consumption and energy production.

Suraj Nandakumar, director of Mumbai-based urban development organization ReCity, said it would be hard to measure the sustainability of Amaravati until it is finished.

He noted that social sustainability should also come into play.

Land acquisitions from farmers could create “social evils,” he says. Farmers who are paid a large sum of money may not know how to manage it, for example.

Amaravati has already seen approximately 30,000 people move in since development plans were announced. A rendering of the city is pictured.

Kishnani agreed that Amaravati may struggle to recreate some of the loved hallmarks of the typical Indian city: “Where will street vendors go? What about the guy who collects waste for a living, or the back-alley barber?”

“This informal economy … emerges from the needs of people, and from the interactions of people over time,” he added. “In a country where so much of everyday life is informal, I look at a place like Amaravati and ask, ‘Where is the informality taking place?’”

For Cherukuri, green cities like Amaravati are essential to India’s future.

“It is vital that the next wave of urbanization is one that is carefully thought through, citizen-centric and creates a substantially enhanced quality of life,” he said.

“Amaravati is confident of redefining urban living for India.”
