brics.br One of the key topics shaping the future of the BRICS is the development of smart cities supported by emerging technologies, particularly artificial intelligence (AI), to implement solutions for urban mobility, waste management, basic sanitation, energy efficiency, and disaster risk prevention. The smart city concept is evolving to incorporate sustainability, accessibility, and resilience principles.
With the recent expansion of the BRICS to include countries such as Saudi Arabia, Egypt, the United Arab Emirates, Ethiopia, and Iran, the bloc is establishing itself as a leading platform for Global South cooperation. This expansion enhances the group’s diversity while introducing new challenges and opportunities, particularly in the realm of sustainable urbanization driven by technologies such as AI.
In Brasil, approximately 86% of the population resides in urban areas, whereas India’s urban population is just above 35%, with projections of over 40% by 2030 (UN-Habitat, 2023). China, meanwhile, has become a predominantly urban society, with around 67% of its population living in urban centers as of 2024 and a projection of more than 75% by 2035 (World Bank, 2024). The diversity of urbanization stages among BRICS countries requires context-specific solutions and creates opportunities for the exchanges of public policy in a scenario shaped by technological, energy, climate, and demographic transitions.
BRICS and the urban agendaIn 2025, various meetings and forums will focus on strengthening cooperation and exchanging best practices among BRICS cities.
The BRICS International Municipal Forum (IMBRICS), for example, will be held in Rio de Janeiro on May 27–28, 2025. The forum will serve as a platform for local and regional government representatives from BRICS countries to share experiences and promote international cooperation at the municipal level.
As the host city for the forum and the BRICS Summit, scheduled for July 6–7, 2025, Rio de Janeiro is advancing initiatives to integrate artificial intelligence into its urban development strategy.
One such initiative is the “Rio AI City” project, launched at the Web Summit Rio 2025 in April. This project aims to transform the Olympic Park into the largest data processing hub in Latin America. With an initial capacity of 1.8 gigawatts by 2027, expanding to 3 gigawatts by 2032, the project relies on clean energy and abundant water supply. In collaboration with the Massachusetts Institute of Technology (MIT), the SENSEable Rio Lab will use visual AI to map and analyze informal settlements, contributing to urban planning and sustainable urban development.
Initiatives like Knowledge Vessels, which are collaborative and creative environments offering high-tech equipment to users, promote digital inclusion and training in emerging technologies. These actions underscore the city’s commitment to becoming a global hub for innovation and technology that uses AI to foster sustainable development and social inclusion.
Meanwhile, the BRICS+ General Assembly of Cities and Municipalities, to be held from May to July 2025 in Maricá, Rio de Janeiro, will bring together representatives from member states and partner countries to discuss strategies for sustainable urban development and inter-municipal cooperation.
In September 2025, the BRICS Urban Future Forum will be held in Moscow to address priorities established during Brasil’s presidency. The event will promote dialogue about the harmonious development of BRICS megacities with focus on green infrastructure, urban technology, resilient architecture, and sustainability, highlighting solutions based on decarbonization and job creation amid intensifying climate change.
AI and smart cities in the BRICS: ongoing experiencesArtificial intelligence is increasingly being adopted in major BRICS cities, notably impacting urban planning, public service management, and civic engagement.
China is at the forefront of developing AI-powered smart cities, particularly in Shanghai and Shenzhen. Shanghai uses an urban governance platform called "City Brain" that integrates data from transportation, health, public safety, and environmental systems for real-time decision-making. Shenzhen uses AI to monitor air quality and predict energy demand, thereby enhancing power grid efficiency.
In India, Pune is developing intelligent mobility solutions supported by AI, including a public transportation system based on passenger flow analysis to optimize routes and schedules.
In South Africa, Johannesburg and Cape Town have invested in AI-based urban surveillance systems for crime prevention and emergency response. AI is also used to forecast waste generation and manage collection logistics, minimizing environmental impact and improving urban living conditions.
Moscow uses AI to manage traffic, regulate energy use in public buildings, and foster a more connected urban environment. In Siberian cities such as Novosibirsk, AI improves access to sanitation and manages decentralized power networks.
Building on the success of the Rio de Janeiro Operations Center, Brasil is implementing AI-based systems at São Paulo’s Traffic Management Center. These systems are designed to ease congestion and reduce commute times by optimizing traffic light operations in real time.
Meanwhile, Curitiba uses smart sensors and predictive to optimize energy consumption in public buildings. The city has also developed pilot projects for intelligent solid waste collection using algorithm-optimized routes, earning it the 2023 Global Smart City Award.
Smart and resilient cities amid climate changeAs extreme weather events, such as torrential rain and flooding, become more frequent, BRICS cities are increasingly leveraging AI to mitigate flood risks and enhance resilient infrastructure. In India, cities such as Chennai and Mumbai use AI-driven algorithms to forecast flood-prone areas based on rainfall patterns and soil data, enabling more timely and effective preventive measures
In Brasil, cities such as Recife and Rio de Janeiro integrate real-time sensor networks with flood risk maps to issue alerts and coordinate evacuations in vulnerable areas. China's "sponge city" model, which involves redesigning urban architecture to absorb and retain rainwater through floodable parks, permeable pavement, and green roofs, has gained traction in cities like Wuhan and Chongqing.
These approaches combine engineering, urban planning, and artificial intelligence to build climate-adaptive cities with resilient infrastructure and enhanced public safety.
Saudi Arabia, the UAE, Egypt, and Ethiopia — futuristic cities and context-sensitive solutionsProjects such as NEOM in Saudi Arabia and Masdar City in the UAE are icons of AI-based sustainable urbanization. NEOM aims to be a fully intelligent, integrated city that uses AI to manage autonomous mobility, water systems, and renewable energy generation. Masdar uses smart sensors to minimize energy use and AI to forecast demand surges.
Egypt is planning new cities like the New Administrative Capital with digital technologies and AI, including smart lighting and urban surveillance systems. In Ethiopia, pilot projects in Addis Ababa use AI to map high-risk sanitation areas, enabling public health initiatives to prevent sanitation-related diseases.
Cooperation and best practices: The Role of the BRICS and the NDBThe diversity of experiences across the BRICS countries provides a unique opportunity to exchange best practices. Brasil’s BRICS presidency in 2025 will provide a valuable opportunity to strengthen cooperation on urban technologies, bringing together experts, public officials and civil society representatives to discuss smart cities in thematic forums.
The New Development Bank (NDB, also known as the BRICS Bank) plays a central role in this endeavor. Established to finance sustainable infrastructure in its member countries, the NDB could increase lending for AI-driven public service projects, thereby ensuring wider access to digital technologies in major urban centres. Smart city development in BRICS countries must go beyond merely showcasing high-tech capabilities. AI must be used to reduce urban inequalities, promote digital inclusion, and improve the efficiency and accessibility of public services.
South-South cooperation through the BRICS creates active dialogue spaces, and the bloc can establish a joint urban agenda based on sustainability, social justice, and digital sovereignty.
