Worldwide Opportunities on Organic Farms or Willing Workers on Organic Farms, is a loose network of national organisations that facilitate placement of volunteers on organic farms. While there are WWOOF hosts in 99 countries around the world, no central list or organisation encompasses all WWOOF hosts. As there is no single international WWOOF membership, all recognised WWOOF country organisations strive to maintain similar standards, and work together to promote the aims of WWOOF.
WWOOFing aims to provide volunteers with first-hand experience in organic and ecologically sound growing methods, to help the organic movement, and to let volunteers experience life in a rural setting or a different country. WWOOF volunteers ('WWOOFers') generally do not receive financial payment. The host provides food, accommodation, and opportunities to learn, in exchange for assistance with farming orgardening activities.
The duration of the visit can range from a few days to years. Workdays average five to six hours, and participants interact with WWOOFers from other countries. WWOOF farms include private gardens through smallholdings, allotments, and commercial farms. Farms become WWOOF hosts by enlisting with their national organisation.
Examples of WWOOF experiences include harvesting cup gum honey from Ligurian bees at Island Beehive in Kangaroo Island, harvesting Syrah grapes for Knappstein Vineyard in the Clare Valley, and harvesting coffee beans from arabicas in Northern Thailand.
