WWOOF is a world wide network - It started in the UK in 1971 and has since become an international movement that is helping people share more sustainable ways of living. WWOOF is an exchange - in return for volunteer help, WWOOF hosts offer food, accommodation and opportunities to learn about organic lifestyles.
WWOOF hosts are mainly pursuing a simple, sustainable lifestyle. Many are practicing Permaculture or Bio-dynamic growing methods. Some farms are commercial producers, whether full or part time; others are alternative co-operatives or communities.
WWOOF organisations compile a list of organic farms that from time to time welcome volunteer help. When you join a WWOOF organization, you will be sent a copy of this list. It is then up to you to contact the farms that interest you and make your own arrangements with them.
The help you give your host will be wide and variable, including sowing, making compost, gardening, planting, cutting wood, weeding, making mud-bricks, harvesting, fencing, building, packaging, milking, feeding.
The help you give is an arrangement made between you and your host. You should negotiate beforehand with your host so that you know what they expect from you and the sort of volunteering you are happy to do.
The volunteering involved should not be exploitative of either WWOOFer or host. Often hosts themselves work long hours 7 days a week, and may expect you to do likewise. A fair exchange could be 6 hours of solid help per day, 6 days per week, with a full day off each week to relax and explore the area.
Remember that it takes a lot of energy and forethought for hosts to welcome strangers into their home. Your work is in part a repayment for their commitment to making your stay possible.
