Climate change, green house gas emissions, and energy and food securities are highly debated and recognized issues globally. What will cities of the year 2100 will look like? How shall we plan and design for sustainable communities 100 years from now? The International Gas Union held a worldwide competition in 2003 and one of the three award winning projects was Goa 2100 planning based on RUrbanism or rural-urban sustainability framework .
The Goa 2100 was recognized for using sustainability concepts such as ecological footprint, material life-cycle analysis, optimal densities and built-form analysis, and time-budget analysis into planning and designing a city. The planners found that based on availability of renewable, recycling capacity and other resources within the region, Goa should have densities between 150 and 300 persons per hectare and buildings should be six-stories high. By the way, our neighbor, Vancouver, British Columbia won the 1st Place in this competition. The cities (PLUS) award winning entry involved 500 experts and 30 cities across Canada in a 2-year long planning and design effort. Read more here. Planning for sustainability requires innovative approaches and these projects reflect those ideas.
