In the current global context, where more than half of the world’s population lives in urban areas and this figure is expected to continue to grow, achieving sustainable urban development has become an inescapable priority. This is at the heart of Sustainable Development Goal (SDG) number 11: “Make cities and human settlements inclusive, safe, resilient and sustainable.”

The importance of SDG 11

SDG 11 focuses on transforming our cities into places where both the environment and people can thrive. But what does this goal actually entail?

1. Inclusion and accessibility: A truly sustainable city must be inclusive. This means guaranteeing access to affordable housing, upgrading slums, and ensuring that all citizens, regardless of their economic or social circumstances, can benefit equitably from urban infrastructure and services.
2. Mobility and sustainable transport: Urban transport is a critical source of greenhouse gas emissions. SDG 11 promotes accessible and environmentally friendly transportation systems, encouraging public transportation, the use of bicycles and the development of pedestrian spaces.
3. Waste management and resource efficiency: Efficient waste management and the promotion of recycling practices are essential to reduce the environmental impact of cities. It is also crucial to improve resource efficiency to minimize waste and promote the circular economy.
4. Green spaces and air quality: Creating and maintaining green areas is essential to promote biodiversity, improve air quality, and provide citizens with places for recreation and relaxation. Cities that prioritize these spaces contribute significantly to the physical and mental well-being of their inhabitants.
5. Disaster preparedness and resilience: With the increase in extreme weather events due to climate change, it is vital that cities develop resilient infrastructure that can withstand natural disasters and implement risk management plans.

Actions to move towards sustainable cities

The path to urban sustainability begins with collaboration between governments, businesses, communities and citizens. Some key actions include:

• Development of effective public policies: Local governments must lead with policies that favor sustainable transportation, renewable energy and planned urbanization.
• Encourage citizen participation: Involving citizens in urban planning ensures that solutions are inclusive and aligned with real community needs.
• Investments in technology and innovation: Technology offers powerful tools to address urban challenges, from smart mobility applications to more efficient waste management systems.
• Education and awareness: Promoting greater awareness of urban sustainability through education is essential to change behaviors and foster a culture of environmental care.

What can we do as citizens?

Achieving sustainable cities is a monumental challenge, but it is also an opportunity to reimagine how people live in community. As citizens and stakeholders of the planet, each of us has a role in creating urban spaces that are truly inclusive and sustainable. By joining forces, we can build cities that not only serve the needs of today, but also ensure the well-being of future generations. Working towards SDG 11 not only improves our cities, but also brings us one step closer to a more equitable and sustainable world.

some concrete actions that citizens can take to contribute to the sustainability of cities:

1. Use public transport or alternative means: Opting for public transport, carpooling, cycling and walking significantly reduces personal carbon footprint and reduces traffic congestion.
2. Reduce, reuse and recycle: Implementing the three “R’s” in daily life helps minimize urban waste. You can start by reusing cloth bags, recycling materials at home and supporting second-hand markets.
3. Participate in urban planning: Get involved in community meetings on urban planning. Your voice can influence decisions such as the creation of green spaces or the design of infrastructure.
4. Saving energy and water: Small gestures such as turning off unnecessary lights, using energy-saving light bulbs, turning off the faucet while brushing your teeth or installing water-saving devices can have a big impact.
5. Support local markets and sustainable products: Buying local products reduces the carbon footprint of transportation and supports the local economy. Choose products with less packaging or from recyclable materials.
6. Participate in organizing community cleanups: Joining groups that clean parks, rivers or streets helps keep the city clean and fosters a sense of community.
7. Planting and tending community gardens: Contributing to urban green spaces, either by planting trees or tending community gardens, improves biodiversity and air quality.
8. Educate and motivate each other: Talking to friends, family and neighbors about sustainable practices and encouraging a change in habits can multiply the positive impact.
9. Support sustainable policies: Pointing out the importance of voting for representatives and policies that promote sustainable development and urban resilience is essential for large-scale change.
10. Incorporate sustainable technologies in the home: Taking advantage of technologies such as solar panels or rainwater harvesting systems can reduce the environmental impact of your home.

By incorporating these actions into daily life, we not only contribute to a more sustainable urban environment, but we can also inspire others to do the same, promoting positive change throughout the community.
