WWOOF (Working Weekends on Organic Farms, as it stood for then) was born in 1971, when Sue Coppard organised a trial weekend for herself and three other Londoners on an organic farm in East Sussex. Sue arranged a deal with the farmer: they would help out with work that needed doing on the land in exchange for food and accommodation. The weekend was so successful that it became a regular trip, every third weekend.
News gradually spread of 'Sue Coppard's Land Army', and other organic farms got in touch, all keen to offer their hospitality in exchange for help from willing volunteers.
Today, WWOOF stands for World Wide Opportunities on Organic Farms: a truly global phenomenon with over 6,000 hosts in 100 countries.
WWOOF UK became a charity in 2008. With well over 560 hosts in the UK and membership rising sharply year on year, it can't be long before the verb 'to wwoof' makes it into the Oxford English Dictionary.
