Smart Cities Forum to Explore New Approaches to Urban Development

Last Updated 1 hour ago by Kenya Engineer

Nairobi will host the second edition of the Smart Cities Forum on 29–30 October 2026, bringing urban development and technology into discussions about how cities can respond to rapid growth, infrastructure constraints and changing environmental conditions.

Held under the theme Regenerating Our Cities: From Urban Challenges to Smart, Sustainable and Inclusive Futures, the forum will examine approaches to making urban areas more efficient, sustainable and accessible. Its focus comes at a time when cities across Africa and the rest of the world are under pressure to expand essential services while managing congestion, housing shortages, flooding, waste and rising demand for electricity and water.

For engineers, the smart-city conversation extends well beyond digital applications and connected devices. It concerns how roads, electricity networks, water systems, buildings, public transport and telecommunications infrastructure can be planned and managed as interconnected systems rather than as separate projects.

Technology offers new ways to coordinate these services, but the results will depend on the quality of the underlying infrastructure, the availability of reliable data and the capacity of city authorities to turn information into practical decisions.

Beyond the technology

The term smart city is often associated with artificial intelligence, automated traffic signals, connected streetlights, digital public services and sensor-equipped infrastructure. These technologies can improve urban management, but their value depends on the problems they are designed to solve.

A city with an advanced traffic monitoring system may still experience severe congestion if its road network is poorly connected, public transport is inadequate or land-use planning forces large numbers of people to travel long distances to work. Similarly, digital water meters offer limited benefits if a utility lacks the resources to repair leaks, maintain pipelines or extend supply to underserved neighbourhoods.

The more consequential question is how technology can help cities make better use of existing infrastructure while guiding investment in new capacity.

Digital monitoring systems can help water utilities identify abnormal flows and potential leaks. Electricity distributors can use network data to detect faults, monitor demand and plan maintenance. Transport authorities can analyse traffic patterns to improve signal timing and assess the performance of public transport routes.

When combined with geographic information systems, these tools can also help engineers map infrastructure assets, identify service gaps and coordinate construction works.

Such applications are relevant to cities at different stages of development. Established cities can use them to improve the performance of ageing infrastructure, while rapidly expanding urban centres can incorporate digital monitoring and coordinated planning into new projects.

The objective is not to introduce technology for its own sake, but to improve the reliability, cost and accessibility of essential urban services.

Nairobi’s infrastructure challenge

Nairobi provides a useful setting for examining these issues. Its growth has increased demand for housing, transport, electricity, water, sanitation and waste management, while development across the metropolitan area continues to place pressure on existing infrastructure.

The challenges frequently overlap. Construction can damage underground utilities when infrastructure records are incomplete. Poorly maintained drainage channels can worsen flooding and disrupt transport. Uncoordinated development can leave residential areas without adequate access to water, sewerage, roads or public transport.

Addressing these problems requires better coordination among the agencies, utilities, developers and contractors responsible for planning and delivering urban infrastructure.

One practical intervention is the development of reliable digital maps of roads, water pipelines, sewer lines, electricity cables and telecommunications networks. Such information would help engineers identify existing services before excavation, coordinate maintenance and reduce damage caused by construction activities.

Combining infrastructure maps with rainfall forecasts, drainage data and flood monitoring could also help authorities identify vulnerable locations and prioritise improvements before severe weather causes disruption.

These systems are useful only when the underlying information is accurate and regularly updated. Establishing responsibility for data collection, sharing and maintenance is therefore as important as procuring the technology itself.

Nairobi’s experience also illustrates a broader challenge for growing cities: new infrastructure must be designed with future demand in mind, while existing networks require rehabilitation and better management. Digital tools can support both tasks, but they cannot substitute for investment in physical infrastructure.

Artificial intelligence enters urban management

Artificial intelligence is creating additional possibilities for analysing the complex systems that keep cities functioning.

Machine-learning tools can examine traffic data to identify recurring congestion patterns, analyse electricity consumption to forecast demand, or help water utilities identify unusual consumption that may indicate leakage. Combined with equipment monitoring, data analysis can also support predictive maintenance, allowing operators to investigate potential failures before they cause major service interruptions.

For urban planners, the ability to combine population estimates, land-use information, transport patterns and infrastructure capacity could improve decisions about where new services are needed.

However, these applications require dependable data, adequate computing and communications infrastructure, and staff capable of interpreting the results. Poor-quality data can produce misleading recommendations, while automated systems that are not properly tested may introduce errors into operational decisions.

There are also questions of cybersecurity and data governance. Connected infrastructure creates additional points of vulnerability, particularly where digital systems control or monitor essential services. Cities must consider how systems will be secured, who can access the information they collect and what happens if a platform fails.

Procurement decisions are equally important. Municipal authorities and utilities need to understand the long-term costs of software licences, equipment replacement, maintenance and technical support. Depending entirely on a proprietary platform can make future upgrades expensive or complicate the integration of systems supplied by different vendors.

These considerations make smart-city development an engineering, institutional and financial undertaking as much as a technological one.

Planning infrastructure as a connected system

One of the persistent problems in urban development is that infrastructure is often planned and delivered by different institutions on separate timelines.

Roads may be upgraded without sufficient coordination with water and sewerage works. New residential developments may increase demand for electricity and transport before the supporting networks are expanded. Drainage improvements in one area may have limited benefits if downstream channels remain inadequate.

A more integrated approach would bring infrastructure planning, land-use decisions and service-demand forecasts into a common framework.

Digital twins offer one possible tool. These are digital representations of physical assets or systems that can be updated with operational data and used to assess performance under different conditions. Depending on their scope and data quality, they can help engineers test scenarios, examine the effects of proposed developments and identify potential infrastructure bottlenecks.

A digital model of a transport corridor, for example, could combine traffic flows with proposed land-use changes to estimate how future development might affect congestion. A model of an urban drainage network could help engineers assess how changes in rainfall intensity or land cover might affect runoff and flood risk.

Such tools are not a substitute for site investigations, engineering calculations or sound professional judgement. Their usefulness depends on whether they adequately represent actual conditions and whether decision-makers understand their limitations.

For cities considering these investments, the priority should be to identify specific planning or operational problems that better data and modelling can address, rather than building elaborate digital systems without a clear purpose.

The cost of making cities smarter

The transition to more connected urban infrastructure carries significant costs. Sensors, smart meters, communications networks, data platforms and control systems require initial investment, but their ongoing operation also demands funding, maintenance and technical expertise.

For municipalities already struggling to finance roads, drainage, water supply and sanitation, these additional requirements must be weighed against competing priorities.

A phased approach may offer a more practical route. Cities can begin with projects where improved monitoring is likely to deliver measurable benefits, such as reducing water losses, improving street lighting efficiency, monitoring flood-prone areas or coordinating maintenance across utility networks.

The business case should account for the full life of the system, including equipment replacement, software support, staff training and cybersecurity. A project that performs well during its initial demonstration but cannot be maintained after the funding ends is unlikely to provide lasting value.

Public-private partnerships may help mobilise capital and technical expertise, particularly for infrastructure requiring substantial upfront investment. However, contracts must establish clear performance requirements, allocate risks appropriately and protect the public interest. Authorities also need to retain sufficient technical capacity to supervise suppliers and evaluate whether promised benefits are being delivered.

For lower-income cities, access to affordable financing and technologies that can operate reliably under local conditions will be particularly important.

Urban regeneration and the question of inclusion

The forum’s emphasis on regenerating cities raises another issue: how to improve urban environments without limiting the benefits to affluent districts or newly developed commercial centres.

Many cities face the dual challenge of expanding infrastructure into underserved neighbourhoods and rehabilitating established areas where services are unreliable or deteriorating. In these settings, priorities may include drainage, sanitation, safe roads, pedestrian access, street lighting, affordable housing and reliable connections to water and electricity.

Technology can help identify service gaps and guide the allocation of resources, but the investment decisions must still reflect residents’ needs.

Digital public services, for instance, should not exclude people who lack smartphones, reliable internet access or the skills needed to use online platforms. Smart transport systems should improve access to jobs and services for commuters across different income groups. Urban regeneration projects must also consider how redevelopment affects existing residents, local businesses and access to affordable housing.

The same principle applies to environmental resilience. Infrastructure designed for current conditions may prove inadequate as rainfall patterns change, temperatures rise and extreme weather events place greater pressure on urban systems. Drainage, water supply, buildings and transport networks need to be planned with these risks in mind.

For engineers, this means integrating accessibility, environmental performance and long-term resilience into project design, rather than treating them as separate considerations after construction.

A global challenge with local solutions

The questions facing Nairobi are not unique to Africa. Cities worldwide are exploring how digital technology can improve transport, manage energy demand, reduce water losses and prepare infrastructure for climate risks. Their circumstances differ, but the underlying challenge is similar: how to provide reliable urban services as populations, economic activity and environmental pressures change.

There is no single smart-city model that can be applied everywhere. A system developed for a wealthy city with extensive digital infrastructure may not be appropriate for a municipality facing shortages of basic services and limited technical capacity.

Cities need solutions that reflect their own infrastructure, finances, climate, settlement patterns and institutional arrangements. They can learn from one another, but successful approaches must be adapted to local conditions rather than copied wholesale.

The second Smart Cities Forum in Nairobi provides an opportunity to examine these choices and the role of technology in urban regeneration. For the engineering profession, the central task is to connect digital innovation with practical improvements in infrastructure planning, construction, operation and maintenance.

The measure of progress will ultimately be found in the performance of the city itself: fewer service disruptions, safer and more accessible streets, more reliable water and electricity, better-managed waste and infrastructure that can withstand future demands.

Smart-city development will be judged not by the sophistication of its technology, but by whether cities become better places to live, work and do business.
