To put this challenge in perspective, it is well documented that the urban population will almost duplicate by 2050 (4), and growth will be seen mainly in developing countries such as in Asia, Africa and Latin America. Furthermore the persistent challenge to house and foster social inclusion for low-income populations in primary and, more recently, in secondary cities is also well documented. Many of these low-income informal settlements tend to locate themselves in areas prone to risk. While topics such as local vulnerability and risk analysis had limited presence at Rio + 20, challenges such as low income population adaptation and resilience were even more underrepresented as discussion topics.
The “think global, act local” phrase was originally attributed to Patrick Geddes 1915, and subsequently in an environmental context to David Ross Brower, founder of Sierra Club. However this action is still not happening as massively as needed. In Rio + 20, there were panels, round tables and groups for global thinking but far fewer for those acting locally, especially for those facing the challenge of poverty, resilience and adaptation to climate change. This challenge is not yet embedded enough in the planning-environmentalist mindset.
Hopefully, the World Urban Forum in September 2012 in Naples, Italy will address these challenges in a comprehensive manner by linking microclimate change, adaptation and resilience with local policies while fostering sustainability from a local perspective and sharing specific ideas and tools that can inspire planners, government officials, NGO’s and especially communities from around the world.
After all, while climate change touches all communities in all countries, it is the poor who will suffer first and most.

[1] With a population of more than 6,000,000, it was the capital of Brazil for nearly two centuries until Brasilia was constructed. Rio has been a laboratory for innovative and diverse housing policies, strategies and tools, due to a historical abundance of extensive informal settlements called Favelas.
[2] agreement on what sustainability meaning “sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
[3] Between 2011 and 2050, the world population is expected to increase by 2.3 billion, passing from 7.0 billion to 9.3 billion (United Nations, 2011).At the same time, the population living in urban areas is projected to gain 2.6 billion, passing from 3.6 billion in 2011 to 6.3 billion 2050. Thus, the urban areas of the world are expected to absorb all the population growth expected over the next four decades while at the same time drawing in some of the rural population. As a result, the world rural population is projected to start decreasing in about a decade and there will likely be 0.3 billion fewer rural inhabitants in 2050 than today. Furthermore, most of the population growth expected in urban areas will be concentrated in the cities and towns of the less developed regions. Asia, in particular, is projected to see its urban population increase by 1.4 billion, Africa by 0.9 billion, and Latin America and the Caribbean by 0.2 billion. Population growth is therefore becoming largely an urban phenomenon concentrated in the developing world (David Satterthwaite, 2007). |
