The benefits of living in an Ecovillage are innumerable, but how can those benefits be accessed if the Ecovillage itself is inaccessible? As the Earth is increasingly devastated by the impacts of climate change, evidence continues to show that specific communities are more affected. These are the very communities that have historically experienced inequity: including low-income households, communities of color, people with disabilities, and immigrant populations (Gamble 2016). One community-based approach to addressing climate change has been the founding and development of ecovillages, sustainable cohousing communities with shared values and resources. There are more than 10,000 of these ecovillages globally, with a concentration of the communities in the Global North. The reality for many of these communities is that these ecovillages, “despite the frequently expressed interest in diversity, have a homogenous profile that is mainly middle or upper middle class, ethnically ‘white’ with higher education levels” (Dias et al. 2017). This thesis seeks to address the barriers to DEIA (diversity, equity, inclusion, and accessibility) in sustainable community design. Cohousing communities, including ecovillages, throughout the Eastern United States, served as precedents for the design of an ecovillage in Hadley, Massachusetts. By incorporating participatory design methodologies, this thesis responded to the needs of the local inhabitants, while fostering a space welcoming to a diverse population, including groups of people that have typically not been represented in cohousing neighborhoods. Only once ecovillages are welcoming to all can they fully tackle both environmental and social sustainability.
