SDG 11: SUSTAINABLE CITIES AND COMMUNITIES
This chapter seeks to ensure that all cities in the world and settlements human beings are inclusive, safe, sustainable and resilient. More than half of humanity, 4 billion people, live in cities today and this figure is projected to increase to 5 billion by 2030, and that number will only grow. This SDG is of great importance because it is not possible to achieve sustainable development in all senses as presented in the 2030 Agenda without radically transforming the way in which urban spaces are built and managed.
Permanent growth of the urban population is due to the fact that there is a positive overview of urban life. The majority of problems, such as poverty, education or health care, among others, that are presented to the population are the solution to life in a city.
The world's cities occupy 3% of the Earth, but account for between 60% and 80% of energy consumption and 75% of carbon emissions. In the event that everything remains the same and cities experience this organic growth, slums, greenhouse gas emissions, large suburbs, traffic intensity, among others will be boosted.
It is therefore essential to create resilience mechanisms in rural areas to prevent collapse in large cities. Transforming rural ecosystems into sustainable smart territories is contributing to the sustainability of smart cities.
