3. Japan

Horticulturalists, unite! WWOOFing, an acronym for Worldwide Opportunities on Organic Farms, has surprisingly little to do with dogs. 

Instead, it provides those who aren’t afraid of getting their hands a little mucky with the chance to help out on farms worldwide. At one dairy farm in Hokkaido, Japan, you’ll learn how to milk the cows as well as feeding, cleaning and other farming processes. WWOOF annual membership fee is £20. 

4. Ghana

Volunteer HQ offers construction and renovation programmes in Ghana, where volunteers work alongside locals to help improve infrastructure. 

The project focuses on the construction and restoration of orphanages, clinics and schools in the east African nation. But if construction doesn’t tickle your fancy there are also teaching and medical opportunities available. Programmes last one week to six months, costing from £190, plus a registration fee of £160. 

5. Madagascar

Ride the ocean ecotourism wave in Madagascar, volunteering for marine conservationists Blue Ventures.

Working with international research scientists, volunteers identify ways in which the island’s coastal communities can live sustainably by helping to survey the region’s reefs. Training includes snorkelling and diving excursions as well as informal lectures. 

The project costs between £700 and £1700 for a three-week placement. Find more details online.
