There’s also never been so much fun to be had from it. There are now more courses, classes, tours, and travel opportunities for the eco-conscious than ever.

In the last twenty years, the Salaam Baalak Trust (SBT) has helped thousands of children come off the streets and into a safe and nurturing environment. SBT has five 24-hour shelters (one devoted to girls), with 50 to 55 children visiting each.

Daniela Ruby Papi, PEPY Tours – Our goal is that people who join us on a trip will be inspired to live, travel and give differently after their trip to Cambodia. We aim to expose travelers to the people and ideas that are having the most impact on the issues we are looking to effect change in: education, the environment, and health. We focus less on service and more on learning, and like to look at our trips as edu-ventures: educational adventures which allow travelers to support projects, programs, and people we believe in.

Danielle Weiss, Planeterra Foundation – My first volunteer experience was a two-month solo trip to the Middle East when I was 19 where I divided my time between volunteering on a kibbutz and travelling throughout Israel and Egypt. This first experience enabled me to make lasting friendships with local people, gain an in-depth knowledge of their daily life, and build the confidence to know that I could travel alone as a single woman.

Amidst the mountainous surrounding, stunning architecture and rich culture of Cusco, you will see bitter reality of young children either working or begging in the streets. 35% of children working in the streets of Cusco are unable to cope with the stress of both working and going to school. This often results in their giving up their studies in order to provide for their families. Other children leave home because they have been abused, neglected or abandoned.

By Nina Fogelman – Discovering opportunities to help develop “Rural Living Tourism” in Peru has become a real passion for me. My visit in September 2007 led me to a community in the Lake Titicaca area that truly captured my heart. I feel blessed to be able to offer opportunities to a segment of Peru’s tourists who wish to participate in unique and rewarding activities, and return to Peru, to my heart of hearts. The local residents of a village called Atuncolla (pronounced atoon coya) are the descendants of the Qolla Kingdom in the Andean highland region.

Community-based ecotourism has been facilitated in Giao Xuan by NGOs, such as Volunteers for Peace in Vietnam (VPV) and the Centre for Marinelife Conservation and Community Development (MCD), which aim to reduce the strain on the local natural resources. They do this by promoting hospitality as an alternative income to destructive fishing and aquaculture techniques which have damaged the nearby national park. The money paid to the host family stays in the community and does not go to any sort of global corporation.

We were the five women who had traveled to Senegal with Women Travel for Peace. Our goal: to fund and help construct a sturdy, concrete well for the women’s farming collective. While this project had begun several months before our arrival with village meetings and discussion, on this, our last day in the village, we were all ready to inaugurate and celebrate our much needed contribution. Women Travel for Peace’s community-based tourism enables women from the industrialized world to work side-by-side with women in the developing world in support of a community project.
