Developer URB has designed a 93-kilometer (58-mile) indoor cycling super highway, shown here in a rendering, that would wrap around the city of Dubai.

If built, the project, known as "The Loop," would provide a car-free, climate-controlled "green corridor" filled for residents to walk, cycle, or run around the city.

As well as paths for cyclists and runners, it would provide areas to relax, play, and exercise.

The enclosed design would offer green spaces with shade and shelter from the extreme heat of Dubai's summer months.

Separate from The Loop is another environmentally conscious design proposed by URB, known as the "Agri Hub." Pictured in this rendering, the project would be a center for sustainable agriculture and tourism in the desert outside of the city of Dubai.

Agri Hub and The Loop would both make use of recycled gray water for irrigation of lush, green public spaces.

URB's CEO Baharash Bagherian wants the Agri Hub to help visitors understand sustainable agriculture techniques such as vertical farming -- growing plants without soil or natural light in vertically stacked beds. This technique uses much less water than conventional methods.

The Agri Hub design includes elements from a working farm, as well as features for tourists. Over roughly 40 hectares, the Agri Hub would host spaces for education and research, as well as eco-lodges, farm shops, and farm-to-table restaurants and cafes.

Bagherian has previously led the designs for Phase 2 of "The Sustainable City" in Dubai and worked on similar green communities currently under construction in Yiti, Oman, and Yas Island in Abu Dhabi. Pictured in this rendering, designs for the Nexgen Sustainable City, which URB has designed for Cairo.

"The whole world is moving towards a greener economy," says Bagherian. "The strongest economies are going to be the ones who are able to transition towards sustainability at the earliest possible opportunity." Pictured in this rendering, designs for the Nexgen Sustainable City.
