Beyond the smart campus: creating resilient, sustainable and livable cities

Siemens hosted a partner event at World Cities Summit 2021, themed ‘Liveable & Sustainable Cities: Adapting to a disrupted world’, to discuss with experts and technology leaders some of today’s burning questions: How can we create strong ecosystems to ensure safe, sustainable and livable cities in the future? Which obstacles do we see and how do we overcome them? What are the best practices in this field and what can we learn from them?

Liveable and sustainable cities

A changing world is putting new demands on existing campuses and altering the way that new ones are developed. Global warming is creating an urgent need to reduce carbon emissions, reduce pollution and protect resources. This in turn is driving city campuses to look for new ways to be less wasteful, to make their environments carbon neutral and to reduce and decarbonize their energy use.

Smart food production for smart cities


Cities will be home to 66% of the global population and consume over 80% of the world’s food by 2050. In the meantime, one-third of the food produced for human consumption is being lost or wasted, the equivalent of 1.3 billion tonnes per year. This waste does not include the land, water and energy that went into producing it. Cities hold the key to unlocking the potential to not only satisfy this increasing demand for food but also improve livelihoods, citizens’ health and the natural environment.

In this panel, we look at how cities, by growing more food locally and using zero waste and low energy technologies, can help to reduce carbon footprint, minimize the distance that food is transported and improve water efficiency.

A resilient smart city: how to ensure security in the face of crisis and disruption


Our lives have witnessed unprecedented change since the pandemic erupted over a year ago. While COVID-19 drags on, climate change continues to be the biggest challenge of our time. 

Still, urbanization is accelerating, and more people are expected to inhabit cities in the next decades. As cities become more crowded, there’s an increasing need to make them safer and more resilient. This is where digitalization comes in with its critical role in crisis management. Our panelists discuss the pandemic’s impact on existing trends, as well as shifting priorities to deliver safer cities. 


Dream or reality: Demystifying the digital twin for city campuses


Employing IoT as the flagship technology to harness data efficiently and create digital twins for sustainable urban areas is a hot topic. But the complexity of creating a digital twin for urban areas with various buildings, infrastructure services and roles can be overwhelming. We take a closer look at where IoT innovation is happening today, what IoT has delivered so far and why establishing ecosystems – both for tech and for people – is key to tackling some of the world’s toughest challenges.
