Arcology is a term coined by architect Paolo Soleri, referring to the design and construction of self-sufficient and sustainable urban spaces. It is a combination of the words "architecture" and "ecology." There are several synonyms for the word arcology, including eco-city, ecopolis, sustainable city, green city, and low-carbon city. All these terms indicate a city or urban space that aims to reduce its environmental impact and promote sustainable living. They all strive for a future where cities are harmonious with nature and provide a high quality of life for their residents while minimizing resource consumption and waste. These terms are becoming increasingly important and relevant as we face the challenges of climate change and rapid urbanization.
