What is the article above about? Please describe the city model of the future? What are the characteristics of those cities?

The article discusses the concept of future cities in light of the anticipated increase in the global population, expecting to reach 10 billion by 2050, with nearly 70% living in urban areas. It emphasizes that these cities will need to be "smarter" and more sustainable to effectively manage population growth and enhance the quality of life for residents.

### City Model of the Future:

1. **Smart Cities:**
- Future cities are described as smart urban areas that utilize advanced technologies to improve services, address urban challenges, and support citizens.
- Technologies will enhance efficiency in city operations, such as traffic management systems that anticipate congestion and intelligent lighting that adapts to foot traffic.

2. **Sustainability:**
- Future cities will be designed with sustainability in mind, incorporating ample green spaces and fostering biodiversity. This includes underground and rooftop farming, green roofs, and roof gardens to promote flora and fauna within urban environments.
- The use of renewable and clean energy sources will be prevalent, and urban infrastructures will be designed to be eco-friendly.

### Characteristics of Future Cities:

- **Integration of Technology:** Utilization of sensors and automated systems to improve various city functions, such as waste management and traffic control, promoting efficiency and resource conservation.

- **Green Infrastructure:** Emphasis on natural elements through initiatives like green roofs, community gardens, and biodiversity-friendly spaces, integrating nature into the urban landscape.

- **Renewable Energy Use:** A shift towards using renewable energy sources to power urban systems, reducing dependency on fossil fuels and minimizing carbon footprints.

- **Eco-Friendly Transportation:** Development of computer-controlled public transport options, like electric buses and trains, along with increased pedestrian zones and bike paths, fostering non-motorized modes of transport.

- **Enhanced Liveability:** The combination of smart technologies and sustainable practices will contribute to improved air quality, reduced environmental impact, and an overall higher quality of life for residents.

Overall, the article paints a vision of urban environments that not only leverage technology for better management and services but also commit to sustainability and ecological balance, ensuring a healthier and more livable future for city dwellers.
