In addition to the basics for individual survival, to create the feeling of community a group needs a common vision. This needs to be big enough that everyone feels that they are part of and can contribute towards in someway.
It is a human need to have a sense of purpose, something that inspires people to feel passionate about and it is important for each person to be able to find that within the common vision. This is what holds the framework of a community together.
Some communities have common businesses, for example many like the Kalikalos communities in Greece run workshops. Many of these workshops share the ideas and interests of the people involved in the community. As working on personal self-development is also one of the prime prerequisites to living with many people, offering these types of workshops and having the training and opportunity to attend helps the bonding process. The Findhorn community in Scotland has its own educational program as well as running regular workshops. Findhorn community has many businesses under its umbrella and nurturing enterprise has always been part of their shared vision.
Growing food and self-sufficiency are also common aims of community. Sometimes this is done communally and at other times involves individuals, families or teams. Not everyone has the same propensity for gardening or the same work ethic and if gardening is on common land this can lead to feelings of resentment if some people do more work than others. This can split groups rather than bond them so ongoing planning, communication and evaluation are vital.
Many communities are involved with the WWOOF program that facilitates people from all around the globe volunteer four hours of work in exchange for board and lodging. Other schemes such as Workaway and Helpx offer similar programs for a wider range of jobs. A strong community is made more vibrant by the regular influx of young travellers.
