Rising Waters, AI and Smarter Cities – But Are They Just?
Published in Earth & Environment, Research Data, and Sustainability
The Story Behind the Research
The inspiration for this study grew from field visits to flood-prone informal settlements in cities like Cape Town and Harare, where rising waters do more than inundate streets; they wash away livelihoods, hope, and dignity. I remember standing ankle-deep in stagnant water in Khayelitsha, listening to a resident say, “We don’t just fear the floods. We fear being forgotten.”
This statement haunted me. While policy briefs and technical reports praised “smart city” solutions, the communities I worked with were struggling to access even basic drainage. That tension, between technological promise and urban neglect, sparked this inquiry.
I am an urbanist with deep roots in migration, informality, and governance research. But with AI encroaching into planning, I realised I needed to interrogate its implications, not just as a digital tool but as a political actor. Could Artificial Intelligence, I wondered, truly help cities adapt to flooding in ways that are equitable and accountable?
Listening to Voices from the Margins
This paper doesn’t emerge from ivory towers; it’s shaped by years of engagement with those living on the edge of the urban fabric. From Lagos to Jakarta, Dhaka to Maputo, informal settlements house nearly a billion people globally. These spaces, what I call "rough neighbourhoods"—aren’t simply informal; they are systematically excluded, poorly mapped, and left out of most technological interventions.
Through workshops, community dialogues, and participatory mapping projects, I’ve learned that residents often have deep local knowledge of flood patterns, where water will pool first, which structures will collapse, and who will be left behind. Yet these insights rarely inform AI models.
This gap in inclusion is not a side issue, it is the issue.
Theoretical Lenses and Conceptual Innovations
In this work, I argue that AI is not a neutral tool. It is embedded in what I call the flood-tech frontier, a space where climate risk and digital innovation collide. The problem? This frontier is too often technocentric, blind to justice, and driven by metrics rather than meaning.
I introduce a socio-technical systems perspective, which treats AI as a governance actor. This means looking at who designs the algorithms, who has data access, whose needs are prioritised, and who gets excluded. From this emerges a new concept: algorithmic exclusion, a phenomenon where entire communities are left out of AI-driven adaptation efforts because of poor data, weak institutions, or digital inequality.
I also offer a justice-oriented framework for AI governance, arguing that we need not just smart systems, but just systems.
Challenges in the Field
Doing research at this intersection was both intellectually thrilling and emotionally demanding.
One major challenge was the lack of Global South representation in AI studies. Most models are built using data from places like the US, Japan, or Western Europe, then applied wholesale to Nairobi or Dhaka. This not only reduces effectiveness—it reinforces epistemic injustice.
Another difficulty was translating the voices of marginalised communities into academic language without losing their urgency or agency. I found myself constantly asking: how do I honour these stories without appropriating them?
Finally, it was humbling to see how digital divides mirror physical inequalities. Cities with the least flood infrastructure also had the least digital capacity, precisely where AI could help most, yet where it's least effective.
Key Findings
Here’s what the review of 20 peer-reviewed articles between 2014 and 2024 revealed:
- AI can predict floods with impressive accuracy. Machine learning and deep learning models (like neural networks) are powerful tools for early warnings and risk maps.
- But these models work best where data is rich and institutions are strong. That’s rarely the case in informal settlements.
- AI often excludes communities most at risk. This happens due to poor data, lack of local engagement, and opaque decision-making.
- Very few AI tools are designed with community input. Participatory design is missing, and without it, solutions are often irrelevant or misdirected.
- Algorithmic fairness is a real concern. Who decides what counts as risk? Who gets alerted first? Whose needs are prioritised?
In short: AI helps cities respond faster—but not necessarily fairer.
Why It Matters
In a world facing accelerating climate shocks, we cannot afford to widen inequality in the name of innovation. AI offers exciting possibilities, but without ethical frameworks and governance reform, it risks becoming a tool of exclusion.
This study contributes to a growing call to decolonise digital adaptation, ensuring that local knowledge, community agency, and historical justice inform our technological futures.
The findings are particularly urgent for policymakers working on SDG 11 (Sustainable Cities), SDG 13 (Climate Action), and SDG 10 (Reduced Inequalities). They signal the need for co-produced adaptation strategies, where local voices shape AI deployment from the start.
Reflections and Hopes
I hope readers come away with a deeper appreciation for the complex politics of flood adaptation in the digital age. Technology is not destiny. We must ask: AI for whom? By whom? With what consequences?
Urban planners should rethink how they use digital tools. Policymakers must fund inclusive data ecosystems. Donors should support projects that prioritise community-led innovation. And students? They should be encouraged to ask tough questions, challenge hype, and centre justice in all design.
A Note to Fellow Researchers
If you’re doing work in precarious, data-poor, or highly politicised contexts, take care. Ethical dilemmas are inevitable. Emotional burnout is real. But so is the power of your work to illuminate what’s ignored.
Don’t be seduced by fancy models or flashy metrics. Listen to the ground. Question assumptions. And above all, stay accountable to the people whose stories shape your research.

Climate Change and the Future of Society: Risks, Resilience, and Transformation
Climate change is the most significant anthropogenic challenges of the 21st century. The activities of mankind writ large are ramping up greenhouse gas emissions, land-use change and industrial activity. Global warming, severe weather, increased sea levels and biodiversity loss are the result of this. Long-term alterations in weather conditions is climate change. It also refers to the changes in climate patterns at regional levels on a global scale. The fast global warming process has started from pre-industrial era. Until the beginning of the 21st century, 1850 to 1900 was by a large margin. These days, the climate is mainly influenced by anthropogenic activities. Climate change and its manifestations are widely recognized as threat multipliers. It jeopardizes both the future global and regional peace and security. An urgent need exists to take climate change and the future of society seriously.
The future of society and climate change are the focus of this special issue, which examines critical levels of concern. Set of forward-looking scientific contribution in this special issue. They review the risks, resilience, and transformations associated with climate change for sustainable development and how they may impact the success of SDGs by the year 2030. The subject is quite relevant as climate action and sustainable development are interdependent, which is acknowledged in the Paris Agreement and the 2030 Agenda. In order to mitigate climate risk to the SDGs, global action is needed on climate change mitigation, adaptation and resilience building so that multiple benefits can also be realised which will enable us to achieve SDGs in a synergistic way. One example would be to move to renewable energy, which could both lower emissions and increase access to clean energy, thereby advancing progress on climate action and affordable clean energy. We can achieve progress on food security by managing the risks of climate impacts on sustainable development of agriculture and livestock models in the country. According to estimates, 80% of SDG targets can possibly be supported by climate mitigation actions.
Researchers world over are invited to contribute in computer science, environmental science, social sciences, economics, policy science, urban studies and allied fields. This Special Issue aims to provide novel contributions from a variety of theoretical and empirical perspectives. The results will trigger new initiatives and contributions from researchers, practitioners and policy makers in the field. It will be produced a new way to model risks and formulating strategies to achieve co-benefits and synergies of low carbon development and sustainable development goals.
Potential themes and topics include, but are not limited to:
The special issue “Climate Change and the Future of Society: Risks, Resilience, and Transformations” has potential themes and topics that may include wide-ranging interdisciplinary thematic areas illustrating complex linkages between climate disruption and the UNSDGs by 2030 and beyond. They consist of:
Synergies and Trade-offs in Climate Action and SDG Achievement:
Climate action must deliver multiple SDGs for strengthening synergies and avoiding trade-offs. Illustration includes renewable energy transitions are compatible with low carbon growth (SDG 8), they also support affordable energy (SDG 7), climate action (SDG 13) and energy access for the poor (SDG 1). Such a development must not cause costly trade-offs such as large scale bioenergy deployment competing with food security (SDG 2) or land use (SDG 15) among others.
Climate Risks and Vulnerabilities Impacting SDGs:
Climate change severely affects sustainable development practices. Food production and availability of water resources are impacted by warming and extreme weather events. Furthermore, an additional global threat to people’s health is climate change. In addition, climate change is affecting the pattern of disease in the world. The rise in temperature all around the globe is adversely impacting the ecosystem. Most significantly, the greatest impact of climate change has been seen on poor and vulnerable people.
Building Resilience through Integrated Approaches:
Examination of Nature-based Solutions, Ecosystem-based Adaptation, and Disaster Risk Reduction will occur. Research on how climate-resilient infrastructure affects one’s adaptive capacity (SDG 13.1), and strengthening social protection systems to reduce inequalities (SDG 10). Resilient communities can be supported by this NbS and EbA.
Transformative Pathways and Systemic Change:
Efforts to achieve fair low-carbon societies have led to significant changes in energy decarbonisation, sustainable industry, sustainable food, land and water, oceans, and digital revolutions for sustainability. The aim of this workshop is to discuss conceptualising and implementing the just transition through a gender and inequality lens.
Sectoral and Regional Case Studies:
Contributions on agriculture and food systems resilience (e.g., drought-tolerant crops, sustainable land management), water and soil resource management, renewable energy adoption, urban planning for climate-resilient cities, health-climate intersections (e.g., heat-related illnesses, vector-borne diseases), and biodiversity conservation amid changing climates.
Governance, Policy, and Finance for Synergistic Progress:
Analyzing enabling conditions like climate finance, policy coherence between the Paris Agreement and 2030 Agenda, loss and damage mechanisms, carbon border adjustments, and international cooperation to accelerate SDG-aligned resilience-building and equitable transformations.
Equity, Justice, and Intersectional Perspectives:
Addressing psychosocial dimensions, gender and intersectionality in adaptation, indigenous knowledge integration, and efforts to prevent climate change from exacerbating inequalities or reversing development gains.
These themes draw on emerging research trends, including renewable energy, ecosystem services protection, life cycle assessments, food security in vulnerable regions, policy synergies, and remote sensing applications, while inviting empirical, theoretical, and modeling-based studies to foster global collaboration and inform pathways toward a resilient, sustainable future.

Gender, Environment, and Sustainability: Bridging Gaps and Building Future
The pressing challenges of environmental degradation and climate change demand innovative solutions that are sustainable, inclusive, and equitable. Gender, as a critical dimension of social structure, shapes the vulnerabilities, experiences, and responses of communities worldwide facing environmental risks. Women play diverse and pivotal roles as leaders, decision-makers, resource managers, activists, and scientists in addressing ecological issues; yet, they continue to face barriers to access, participation, and recognition within environmental sectors.
This collection, "Gender, Environment, and Sustainability: Bridging Gaps and Building Future," explores the intersection of gender and the environment as a transformative lens for achieving sustainability and social justice. The collection welcomes contributions that examine how gender-based disparities influence environmental outcomes, how women’s empowerment enhances ecological stewardship, and how Sustainable Development Goals (SDGs) can be advanced through gender-inclusive policies and practices. Submissions may cover topics such as gendered impacts of climate change, women’s leadership in environmental governance, gender mainstreaming in sustainability science, and case studies from diverse social, cultural, and geographical contexts.
By bringing together global perspectives, empirical analyses, and practical frameworks, this topical collection aims to foster rigorous research and constructive dialogue on the shared journey toward a more sustainable and equitable future for both genders. Researchers, practitioners, and policymakers from diverse backgrounds are invited to contribute their insights and innovations to bridge the gaps and build resilient pathways for future generations.
