Towards the backdrop of escalating local weather threats and deepening city inequality, the South African Establishment of Civil Engineering (SAICE) hosted the 2025 SAICE Environmental Engineering Division (SEED) breakfast in July. The occasion drew main voices in science, expertise and concrete growth into one shared dialog – how can African cities prepared the ground in climate-smart people-centred infrastructure?
Held in KwaZulu Natal, a province that has weathered a few of South Africa’s most extreme local weather shocks, the occasion marked a renewed name for civil engineers, planners and policymakers to undertake a radically inclusive, context-driven strategy to local weather motion. In Southern Africa, greater than 30 million individuals are affected by extreme drought with widespread crop losses attributable to excessive local weather change(1). Lesotho, Malawi, Namibia, Zambia, Zimbabwe and Botswana have declared a state of emergency attributable to drought with tens of millions in want. In North and West Africa, flooding and temperature fluctuations are having a extreme affect throughout societies, economies and communities(2). Based on the UN World Meteorological Group, the typical floor temperature was 0.86 levels centigrade above the 1991-2020 common on the continent.
SEED Chairperson, Mathapelo Extra, opened the session with a systems-focused message about local weather adaptation within the African engineering context. “We have to transfer in the direction of programs worth,” she mentioned. “No matter human and enterprise actions we do have to be inside what the pure atmosphere can present.”

Reflecting on planetary boundaries and the dangers of world overshoot, she added: “We will’t maintain ready for cash to reach. The World South receives 5 to 10 occasions much less adaptation finance than wanted, so what can we do in our area as Africans? That is the query we should be answering and the way we should be pondering. As a result of clearly, the cash isn’t flowing our means, and we will’t wait.”
Keynote speaker, Sibo Mabuze-Kaluw, co-founder of Africans Altering Africa, an organisation devoted to driving constructive societal change on the African continent, challenged engineers to essentially rethink what a resilient African metropolis seems to be like. “Africa is urbanising quicker than every other area,” she mentioned. “However are we constructing cities that may survive the subsequent flood, drought or heatwave?”
Mabuze-Kalow contrasted the continent’s fast development and digital fragmentation with slower, broadband-based growth within the World North. “We will’t import blueprints. Our city inhabitants remains to be rising at 3.5% yearly and plenty of of our individuals dwell in formal settlements, off the planning radar. Our infrastructure remains to be being inbuilt actual time.”
In 2010, the share of Africans dwelling in city areas was round 36% however this quantity is predicted to extend exponentially to 60% by 2050. This city inhabitants development will anticipate cities on the continent to ‘take up a further 600 million individuals, reaching a complete of 1.2 billion’(3). At present, 700 million individuals dwell in city areas, and this quantity is predicted to succeed in 1.4 billion by 2050 at a charge of development that has by no means been seen earlier than in human historical past(4).
Mabuze-Kalow’s imaginative and prescient of climate-resilient urbanism was sensible and deeply rooted in citizen participation:
Knowledge-informed, people-centred planning utilizing GIS, drone mapping, and community-sourced knowledge by way of WhatsApp or USSD; Local weather-smart infrastructure that adapts in actual time, together with IoT flood sensors and predictive warmth modelling; Digitally managed utilities for good metering, power entry and waste optimisation; Inclusive mobility platforms that combine strolling, taxis, and GPS-tracked transport with digital fare programs; Multilingual, low-tech programs that serve the digitally excluded.
“These aren’t billion-dollar tasks, they’re good, grounded and African,” she mentioned.
Local weather shocks are additionally enjoying a big position in worsening transport inequity. Vuyi Majola, Public Transport Integration Specialist at CityCon Africa, expanded the dialog into the mobility area. Her focal instance, the Tugela River Bridge in rural KwaZulu-Natal, captured the very important significance of infrastructure and mobility as a justice concern.
“Think about a 15-kilometre journey to a clinic out of the blue changing into a 163 kilometre spherical journey as a result of the river floods and the bridge turns into impassable,” she mentioned. “The bridge is there, sure, however individuals can’t cross it and have been rendered motionless. That is each an engineering downside and a dignity downside.”
She illustrated how a scarcity of mobility disproportionately impacts ladies and low-income households. “Ladies stroll greater than males on this nation, and when mobility programs don’t work, its ladies who’re left behind, unable to succeed in clinics, grants or faculties.”
Majola emphasised the significance of fundamental instruments for resilience which included SMS alerts from ward councillors, community-based knowledge assortment, and pedestrian bridges that guarantee entry even when the river swells. “We don’t all the time want difficult expertise, typically the answer is so simple as a walkway,” she mentioned. “Let’s cease constructing for communities and as a substitute construct with them.”
CEO of CityCon Africa, Andile Skosana, challenged engineers and planners to construct bridges between disciplines. “We have to have controversial conversations which can be each cordial and brave,” he mentioned “Too usually, we design technically excellent infrastructure that fails socially. The bridge remains to be standing, sure, however the individuals it was meant to serve are caught on the opposite aspect.”

He echoed Majola’s level that engineering choices are finally social ones and proposed a transfer from transport-oriented growth to development-oriented transit. This strategy acknowledges the fact that casual mobility programs like taxis and strolling usually pre-empt formal infrastructure and asks that future growth is constructed round how individuals transfer so it doesn’t miss the purpose.
The ultimate keynote got here from Professor Debra C. Roberts, an acclaimed South African scientist and practitioner extensively recognised for her pioneering work on the intersection of local weather science, city sustainability and coverage. “We’re already dwelling in a harmful local weather,” she mentioned. “Even 1.5 levels isn’t protected, it’s simply much less harmful than 2 levels – each tenth of a level issues.”
Drawing on the most recent synthesis report by the Intergovernmental Panel on Local weather Change (IPCC), Roberts laid out the fact. World emissions should fall by 60% by 2035 to have any hope of limiting warming to 1.5 levels centigrade and Africa is heating twice as quick as the worldwide common. Adaptation is just not sufficient, there are actually onerous limits with ecosystems and individuals are too susceptible to regulate.
“Design smarter, construct bolder and lead in another way,” she mentioned, “Don’t ask if it can work as a substitute ask if it can adapt or survive. The science provides us a piece programme, now we act. No person can sit this out – not residents, not metropolis engineers, not insurance coverage corporations, not nationwide governments. Everybody should lead.”
Infrastructure designed at this time have to be constructed for an unpredictable, hotter and extra unequal world.
Closing the occasion, extra re-emphasised the necessity for native management and shared possession. “The time has come to behave, to establish who must be within the room, to share sensible instruments and construct programs that serve African realities.”
