Urban development with a surprise effect: anyone who believes that innovation in urban planning is a one-way street from Europe to the South is very much mistaken. The Global South is becoming a laboratory for the urban future – with bold solutions that should make us in Germany, Austria and Switzerland think twice.

Beyond the master plan: urban development in the Global South as a contemporary laboratory

Anyone who locates urban innovation exclusively in the North underestimates the dynamism and creativity that can be observed in cities in the Global South on a daily basis. While in Central Europe the demand for completeness, safety and perfection dominates planning, urban development in metropolises such as Lagos, Jakarta or Lima means one thing above all: improvisation, adaptability and pragmatism. The reasons are obvious – explosive urbanization, scarce resources, weak institutions and huge social challenges require different answers than those provided by traditional planning manuals.

In the Global South, cities often grow so fast that no land use plan in the world can keep up. This gives rise to informal settlements that expand beyond official planning guidelines. What at first glance appears to many planners to be a loss of control is, on closer inspection, a complex system of self-organization. Residents organize infrastructure, build paths, drain water, shape neighbourhoods – and develop enormous resilience to shocks and crises in the process. This shows that a city is never just what it says on paper, but what people make of it with creativity, courage and improvisation.

This different kind of urban development is not romantic, but it is instructive. Because it produces what is often staged as an expensive innovation process in the Global North: flexible forms of living, multifunctional spaces, dense neighborhoods, short distances, collective use of resources. While European cities often struggle to reallocate space for temporary use, in cities such as Nairobi or Dhaka new markets, workshops and meeting places are springing up every day that adapt flexibly to changing needs.

This does not mean that all problems have been solved. On the contrary: informality often goes hand in hand with a lack of supplies, a lack of legal security and a precarious living situation. But it also forces a planning culture that focuses less on control and more on facilitation, moderation and cooperation. Planners are becoming facilitators, mediators and networkers – traditional hierarchies are dissolving in favor of flexible, often temporary solutions.

For the German-speaking world, this is a provocation – and an opportunity. Because the challenges of the 21st century, from climate change to migration, demand new, flexible answers. The cities of the Global South show how change can succeed under pressure, which cultural and social resources can be activated and that perfection is often the enemy of the good. It is worth taking a closer look.

Informal settlements: From an urban planning problem to a resource for adaptability

Few topics polarize urban planning more than the phenomenon of informal settlements, often hastily dismissed as slums or favelas. However, a closer look reveals that these structures are not merely an expression of poverty and disorganization, but rather highly adaptable, resilient systems that hold key lessons for urban development. In megacities such as Mumbai, Rio de Janeiro or Kinshasa, a significant proportion of the population lives in informal neighborhoods – and their ingenuity ensures that the urban whole functions at all.

The dynamics of informal settlements are impressive. They often grow in a very short space of time, adapt to topographical, climatic and social conditions and have social networks that are unparalleled in their density and resilience. The supply of water, electricity and sewage is often organized by local initiatives, markets and services emerge spontaneously and disappear again depending on demand. This ability to create functional structures with minimal resources is the result of collective learning and constant improvisation.

Formal urban planning is often helpless in the face of this phenomenon. Spatial order, building regulations and infrastructure standards seem to be suspended in the world of informal settlements. However, instead of reflexively opting for demolition or resettlement, many cities in the Global South are moving towards regularizing informal settlements, retrofitting infrastructure and actively involving residents in development. One prominent example is the Favela Bairro program in Rio de Janeiro, which focuses on integration rather than displacement and thus reduces social tensions.

In Cape Town, too, participatory approaches are proving to be more sustainable than top-down, large-scale projects. In the informal settlement of Khayelitsha, flexible, small-scale solutions for water, electricity and waste disposal were developed together with residents – with the result that acceptance and maintenance of the infrastructure are significantly higher than with traditional large-scale projects. The central message: if you make those affected into participants, you get solutions that really work.

For planners in German-speaking countries, this is both a challenge and an invitation. The structural flexibility, social innovation and participatory methods of informal urban development offer valuable impulses, particularly for the transformation of existing neighborhoods, overcoming the housing shortage or the integration of immigrants. What was born out of necessity in the south can become a resource for a resilient, inclusive city in the north – provided that people are prepared to swap control in favor of cooperation.

Mobility, public space and climate adaptation: Driving innovation in the Global South

When it comes to urban mobility, many cities in the Global South are characterized by a wild juxtaposition of different means of transport – from matatus in Nairobi to jeepneys in Manila and mototaxis in Lima. What appears chaotic from a Central European perspective is actually a highly flexible, demand-oriented system that closes gaps where formal transport planning reaches its limits. Informal mobility services react dynamically to demand, adapt to new districts, are affordable and accessible at low thresholds. In Bogotá, for example, the famous TransMilenio bus system was introduced to counteract excessive individual motorization and gridlock. It is supplemented by a dense network of informal buses that connect the periphery and keep the city mobile.

Public space in the Global South is rarely uniformly designed, but is collectively appropriated and constantly redefined. Markets are set up on traffic islands, parks become sports fields, streets become social meeting places. Especially in cities with little formal green space, the flexible use of public spaces plays a central role in social life and resilience to environmental crises. In Jakarta, for example, inner-city riverbanks also serve as transportation routes, markets and places of refuge in the event of flooding. This multiple use is not only pragmatic, but also makes ecological sense – it reduces land consumption and increases adaptability to climatic extremes.

In the Global South, climate adaptation is not a theoretical game, but a daily necessity. Cities such as Dhaka, which are regularly threatened by flooding, are developing low-tech strategies that achieve great results with the simplest of means. Mobile flood bridges, floating gardens and temporary shelters are examples of a culture of adaptation that relies on individual initiative, creativity and collective action. In Nairobi, mangrove forests are being restored to mitigate flooding and promote biodiversity – a strategy that also serves as a model for the renaturation of urban rivers in Europe.

All these examples show: The innovative strength of the Global South lies not in high-tech solutions, but in the ability to create systems that work with limited resources and under uncertainty. The methods developed there are often robust, scalable and surprisingly adaptable to new contexts. For the cities of Central Europe, which are increasingly confronted with resource scarcity, climate risks and social segregation, these approaches offer valuable sources of inspiration – and a plea for more pragmatism and experimentation.

Of course, not everything is transferable. Legal framework conditions, social inequality and a lack of planning security pose major challenges. But the courage to try things out, to open up spaces temporarily, to improvise with citizens instead of dictating – these are attitudes that are also urgently needed in Hamburg, Zurich or Vienna.

Participation, governance and urban design: what we can really learn

Participation is rarely a luxury in the Global South, but a bitter necessity. State resources are scarce, administrative capacities limited – so residents take the initiative. Whether in the planning of water infrastructure in Maputo, urban greening in Medellín or securing housing rights in Mumbai: successful projects are created where administration, civil society and business cooperate as equals. The role of the planner is changing fundamentally – from omniscient expert to moderator, mediator and process designer.

In Medellín, for example, the famous “Urban Acupuncture” projects were developed, small, selective interventions with a major social impact. Cable cars connect disadvantaged districts with the city center, libraries and parks are placed at neuralgic points, social programs complement structural measures. Success is based on intensive involvement of the population and a governance structure that allows innovation without losing sight of the big picture. This balance between control and openness is a key lesson for the transformation of European cities.

Urban design also benefits from the pragmatic approach of the South. Instead of elaborate master plans, flexible, modular structures are developed that can grow and change over time. In Bangkok, for example, temporary markets are being created that move seasonally and adapt to people’s needs. In Cape Town, public spaces are designed so that they can be used as event venues, emergency shelters or community gardens when needed. This multifunctionality requires fewer resources and strengthens people’s identification with their neighborhood.

An often underestimated aspect: innovation in the Global South is usually low-tech but high-impact. Instead of importing expensive technologies, local materials, craftsmanship and social networks are used. This saves costs, increases acceptance and creates local jobs. For Europe’s resource-hungry cities, this is an invitation to rethink the relationship between technology, design and social innovation.

Last but not least, it shows that governance models that rely on cooperation, participation and flexibility are also more robust in times of crisis. The pandemic has shown worldwide how quickly centralized governance models reach their limits – and how important decentralized, participatory structures are in order to remain capable of acting. The lesson for German-speaking countries is to have more confidence in local networks, more courage to experiment – and a little less perfectionism.

From theory to practice: transfer potential, pitfalls and future prospects

For planners in Germany, Austria and Switzerland, looking to the Global South is not just an exotic finger exercise, but a real broadening of horizons. The challenges may be different, but the basic urban problems are increasingly similar: rapid urbanization, social change, climate crisis and scarcity of resources. The question is not whether we can learn from the cities of the South, but how – and with what attitude.

The transfer of informal solutions or participatory planning approaches is not a simple copying process. Legal, cultural and social differences must be taken into account. But the principles – flexibility, pragmatism, cooperation, temporary solutions – are universally applicable. Projects such as the integration of temporary uses in Berlin, the expansion of pop-up cycle paths in Vienna or participatory neighborhood development in Zurich show that learning is possible and makes sense.

At the same time, there are risks. Informality must not become a pretext for lowering standards or ignoring social inequalities. Even in the Global South, informal settlements are often places of extreme poverty and insecurity. The transfer of planning approaches must always be linked to critical reflection, social responsibility and long-term perspectives. Those who use the creative energy of informal processes without ensuring basic services, legal security and participation risk new forms of exclusion and precarity.

Nevertheless, the potential outweighs the risks. The cities of the Global South are the involuntary avant-garde of the urban age. They show how cities function under conditions of uncertainty, scarcity and diversity – and how new strengths emerge from apparent disadvantages. For the cities of Central Europe, which have to reinvent themselves on the threshold of a post-industrial age, these experiences are worth their weight in gold.

It is time to broaden our perspective, question routines and renew our own understanding of planning. The future of the city lies not only in exporting European models, but also in the dialog between cultures, in mutual learning and in the courage to try out the unknown. Those who look with curiosity at the improvised solutions of the South today could become role models themselves tomorrow – in terms of resilience, innovation and social urban development.

Conclusion: The Global South as a source of inspiration for the city of tomorrow

Urban planning in the Global South is not an exotic fringe issue, but a reflection of the challenges we are also facing – only in a more concentrated, accelerated and different way. Cities are being created here that deal productively with uncertainty, scarcity and diversity – and in the process produce solutions that are as pragmatic as they are inspiring. From improvised public spaces and participatory governance to creative low-tech strategies: Lessons from the South is an invitation to rethink planning – less as control, more as enabling.

For planners in German-speaking countries, this means: openness to new approaches, the courage to experiment, trust in local networks and the willingness to accept mistakes as part of the learning process. The creative energy and social innovation of informal urbanity should not be seen as a deficit, but as a resource. The Global South shows how cities can succeed even under adverse conditions – and challenges us to strive less for perfection and more for adaptability and participation.

At a time when the challenges are becoming increasingly complex, the exchange between North and South is more important than ever. The future of the city is created through dialog, experimentation and joint learning. Those who are prepared to take the lessons of the South seriously will not only shape the city of tomorrow, but fill it with life.
