Diana Leafe Christian is an author, former editor of Communities magazine, and nationwide speaker and workshop presenter on starting new ecovillages, on sustainability, on building communities, and on governance by sociocracy. She lives in an off-grid homestead at Earthaven Ecovillage in the Blue Ridge Mountains of North Carolina, U.S. She has said that living in an intentional community "is the longest, most expensive, personal growth workshop you will ever take," though others are also associated with this quotation and it's unclear who originated it.

An ecovillage is a traditional or intentional community with the goal of becoming more socially, culturally, economically, and/or ecologically sustainable. An ecovillage strives to produce the least possible negative impact on the natural environment through intentional physical design and resident behavior choices. It is consciously designed through locally owned, participatory processes to regenerate and restore its social and natural environments. Most range from a population of 50 to 250 individuals, although some are smaller, and traditional ecovillages are often much larger. Larger ecovillages often exist as networks of smaller sub-communities. Some ecovillages have grown through like-minded individuals, families, or other small groups—who are not members, at least at the outset—settling on the ecovillage's periphery and participating de facto in the community. There are currently more than 10,000 ecovillages around the world.
