ICLEI – 2012 World Congress

Rio De Janeiro

The ICLEI World Congress 2012 will deal with the pressing issues facing local governments and urban areas in this unpredictable era of change. The Congress will bring our Members, partners, global strategists, academics and NGO’s together. Participants will learn from inspirational speakers and real-life city cases about cutting-edge integrated solutions to the challenges we face.

Every three years, ICLEI members and partners gather at an ICLEI World Congress to showcase their actions over the period and discuss strategies for the following years. The ICLEI World Congress is the main event our association of Local Governments for Sustainability and has been hosted by expressive cities such as Athens, Greece (2003); Cape Town, South Africa (2006); and Edmonton, Canada (2009).

Closely linked to the UN Rio+20 conference, the ICLEI World Congress 2012 will chart the way forward for local governments and their partners to a more sustainable and prosperous future.

This will be the first ICLEI World Congress in Latin America and we are excited to welcome participants to this vibrant and dynamic region.

Session at the ICLEI World Congress

The “nexus” of food, water and energy represents one of the biggest challenges in urban areas. If supplies of these three key resources are not maintained over time to serve human societies as well as the natural ecosystems from which they derive, the basis for all life will be undermined, and cities will not be functional any more.

By now most people are all too familiar with the extended drought in the American Southwest. Pictures of wildfires in California, decimated agricultural lands and the effects of a diminishing water supply regularly make the news. What most people might not know, yet just as devastating, is the potential effect of the 14-year drought in the Colorado River basin on the Southwest’s energy supply. Changes in water supply directly affect power systems in the West, and we watch closely as low water levels in Lake Mead could have an impact on the amount of energy generated from the Hoover Dam.
