Urban planning under pressure: why the global South is providing new answers

When we think of urban development, we often think of the sleek visualizations of European or North American metropolises. But while in Berlin or Zurich the last street lamp in the development plan is still being discussed, in Jakarta, Lagos or Lima new districts are being built every day – often on their own initiative, usually without formal planning, but always with enormous creativity. The reality of the global South is characterized by rapid growth, incomplete infrastructure, social inequality and political uncertainty. It is precisely these conditions that often make classic, linear urban planning impossible here – and force the actors to find solutions that go beyond the conventional.

The global South is an experimental field of extremes. Cities such as Mumbai or Kinshasa are growing at a pace that would make any German building authority break out in a sweat. At the same time, resources are scarce, official planning is lagging behind and the population is acting independently. Informal settlements, improvised mobility solutions and flexible infrastructures are not the exception, but the norm. This is forcing planners, architects and administrations to rethink: what to do when reality is faster than the plan?

This dynamic has given rise to a new generation of urban planners who are experimenting with unorthodox methods. Instead of elaborate master plans, what often counts is quick, pragmatic intervention – a pilot project here, a participatory process there, a temporary market or a self-built playground. The city becomes a stage for experiments that help in the short term, but serve as seedbeds for new urban structures in the long term. It is precisely these “unfinished” solutions that are often viewed with suspicion in Europe, but which keep the city running in the metropolises of the south.

Of course, the challenges are enormous. Climate change, poverty, poor air quality, traffic chaos – the list is long. But it is precisely the need to constantly improvise that has led to innovative approaches in many cities that could also set a precedent in the global North. Be it the use of digital platforms for citizen participation in Nairobi, temporary infrastructure in Cape Town or the integration of informal actors in the urban development of Medellín – the global South is not only a place of problems, but also of solutions.

Germany, Austria and Switzerland could benefit from this pragmatism. Because while in this country discussions about neighborhood developments often last for years, the global South shows how planning can be understood as a process and an experiment. This requires the courage to leave gaps, openness to mistakes and the willingness to learn from the unfinished. This is precisely the big lesson: urban planning must remain flexible – and seek dialog with urban reality, not just with theory.

Informal urbanity: from stopgap solution to source of innovation

When talking about informal settlements, many planners automatically think of slums, chaos and uncontrolled development. But this falls short. Informality in the global South is an urban principle in its own right, based on adaptation, flexibility and community. Whether favela in Rio, slum in Nairobi or barriada in Lima – informal districts are usually much better organized than they appear at first glance. They have their own systems of self-administration, collective infrastructures and social networks that often function more efficiently than official structures.

The emergence of informal neighborhoods is not an exception, but the norm in many cities in the South. More than a billion people worldwide live in such settlements. Yet these districts are anything but static. They grow, become denser, change their use and adapt to new needs. The architecture is improvised, the street layout is flexible, the infrastructure is supplemented or replaced as required. The result is a highly dynamic city that is constantly renewing itself – and is therefore often much more resilient than well-planned settlements.

This also has an impact on the planning culture. In cities such as Dhaka or Lagos, planners have long since stopped working against informality, but with it. They are developing strategies to integrate informal settlements into the official urban structure without destroying their flexibility. This includes participatory upgrading projects that are carried out together with the residents, but also the targeted expansion of infrastructure such as water, electricity or sewage that is tailored to real needs.

The success of such projects depends crucially on how well those involved understand the local context. Those who try to transfer European standards one-to-one usually fail miserably. Instead, empathy, patience and a willingness to question traditional planning instruments are required. Informal urbanity is not a “deviation”, but a logic of its own. It can provide valuable impetus for cities in the global North – for example, when it comes to activating neighbourhoods, the temporary use of space or the integration of marginalized groups.

However, it would be a mistake to romanticize informality. Living conditions in many of these settlements are precarious, and access to education, health and mobility often remains limited. However, the ability to create functioning urban structures under difficult conditions is impressive – and proof that urban development can succeed without formal planning. The big challenge for European cities is to recognize, adapt and further develop this innovative strength – without losing sight of their own standards and requirements.

Participation and bottom-up approaches: Rethinking urban development

Participation has long been a political buzzword in German, Austrian and Swiss cities. But what do real bottom-up processes look like in practice? The Global South provides plenty of illustrative material. In many cities, it is not the administrations but the citizens themselves who are driving change. Whether neighborhood initiatives, cooperatives or informal networks – this is where solutions emerge that are often much closer to people’s needs than technocratic top-down plans.

One example of this is the famous “participatory budgeting” in Porto Alegre, Brazil. Since the 1980s, citizens here have been deciding directly on parts of the city budget – a model that has since been copied worldwide. The highlight: direct participation not only increases the acceptance of projects, but also the efficiency and transparency of the use of funds. In Cape Town, on the other hand, entire districts are being redesigned together with the population – from planning to construction. Residents contribute their knowledge, their needs and their manpower, while the city administration acts as a coordinator.

Digital tools are also playing an increasingly important role. In Nairobi, for example, city makers are using open source maps to record and improve informal settlements. In Jakarta, social media platforms are used to report traffic problems and discuss solutions. These approaches are not only innovative, but also highly adaptable – an important advantage in cities that are constantly changing.

This opens up exciting prospects for planners in the Global North. The classic division between experts and laypeople, between planning and use, is constantly being erased in the global South. Flexibility, creativity and the courage to experiment are in demand – qualities that are often lacking in European contexts. Such participatory, experimental methods could provide new impetus, particularly in the development of new neighborhoods, the conversion of existing areas or the design of public spaces.

However, the same applies here: Not every participatory process is automatically successful. Power asymmetries, a lack of resources or a lack of transparency can slow down or even reverse bottom-up approaches. Anyone who wants to learn from the Global South must therefore take a close look at which factors contribute to success – and which risks exist. This is the only way to meaningfully transfer the experiences to your own context.

Technology and governance: innovations between improvisation and systematics

Innovative urban planning in the global South is not just a question of pragmatism and participation, but also of technology and governance. While the introduction of urban digital twins or smart city concepts is still being discussed in Europe, cities such as Medellín, Singapore and Kigali have long been relying on digital tools – albeit with a very different focus. In many cases, it is less about high-tech and more about low-tech solutions that are fast, cheap and robust.

Medellín in Colombia provides an outstanding example. The city has undergone an impressive transformation in recent decades – from the most dangerous city in the world to an international role model for social innovation. At the heart of this development are the so-called “Integral Urban Projects”, which interlink technical, social and infrastructural measures. These include cable cars, escalators, solar lighting and digital information systems, which are used specifically in disadvantaged neighborhoods. The decisive factor here is the combination of technical innovation and participatory governance – a model that could also be of interest to European cities.

In Africa, on the other hand, many cities are using mobile technologies to make urban services accessible. In Nairobi, the M-Pesa payment system enables access to finance, while apps such as Ushahidi help to collect and disseminate information in the event of disasters. These solutions are characterized by their low threshold and scalability – characteristics that are also increasingly in demand in the Global North, for example in the development of digital participation platforms or the collection of urban data.

At the same time, the Global South shows that governance does not always have to function according to the classic model. It is often hybrid structures – mixtures of state control, civil society involvement and private sector initiative – that drive innovation. This requires new forms of cooperation, flexible legal frameworks and a willingness to share responsibility. Especially in times of increasing complexity and uncertainty, this openness to new governance models can also provide valuable impetus in Europe.

The great art is not to see technology as an end in itself, but to always use it in the service of city dwellers. The Global South shows that innovation is often born out of necessity – and that improvisation and systematics need not be opposites. For planners, architects and city administrations in the DACH region, this means: less fear of making mistakes, more courage to experiment – and a willingness to learn from others, even if the context initially seems unfamiliar.

European cities in the mirror: lessons, opportunities and limitations

So what remains when we look at the cities of the global South? First of all, the realization that urban development is never a finished project, but an ongoing process – characterized by uncertainty, conflict and surprises. The Global South shows how important flexibility, adaptability and creativity are. At the same time, it warns us to be cautious: not every solution can be transferred one-to-one, not every context is comparable.

For German, Austrian and Swiss cities, this means: openness to new approaches, but also critical reflection. The integration of informal structures, the promotion of participatory processes and the use of digital technologies can make a big difference – if they are designed in a clever and context-sensitive way. It must always be borne in mind that the framework conditions in the Global North are different: Legal certainty, social standards, political stability and technical resources differ fundamentally from the starting positions of many cities in the South.

Nevertheless, there are numerous starting points for fruitful exchange. European cities can learn from the Global South, particularly when it comes to dealing with uncertainty, activating local resources and designing resilient neighborhoods. The big challenge is to allow the “unfinished”, to understand mistakes as learning opportunities and to see the city as a living laboratory. Those who have the courage to leave well-worn routines behind can initiate innovations that are urgently needed in stable, prosperous societies.

At the same time, we should be wary of romanticizing. Not every improvised solution is sustainable, not every participatory project is successful. The “best practice fetish” can lead to complex interrelationships being ignored or problems being obscured. What remains is the invitation to change one’s perspective, to question one’s own assumptions and to embark on the urban adventure – with all its contradictions, risks and opportunities.

In conclusion, the future of the city is not created in a vacuum, but through exchange, experimentation and constant learning. The global South is no longer just an object of European development aid, but an active player that is reshaping global urbanism. Anyone who recognizes this can approach the challenges of their own urban development with a fresh perspective – and become part of an urban movement that is setting standards worldwide.

Conclusion: a change of perspective as the key to the urban future

The lessons from the global South are neither patent remedies nor romantic folklore. They are both an invitation and a challenge to understand urban planning as an open, learning process. In the midst of uncertainty, scarcity and dynamism, solutions are emerging that can also provide valuable impetus for German, Austrian and Swiss cities: More flexibility, more participation, more courage to experiment. The Global South shows that innovation often arises where planning reaches its limits – and that real resilience arises from the interplay of technology, community and improvised creativity. Those who dare to change their perspective in this way can not only avoid mistakes, but also shape their own urban development in a sustainable, social and vibrant way. Because the city of tomorrow will not be designed at the green table, but built in real life – and that applies all over the world.
