This is something many Trekkers ask, and it is quite a difficult thing to consider. What we do at Project Everest Ventures is manage expectations. We are completely transparent in the communities we work in, letting them know why we are here, how long we will be there for and making sure we never make a promise we cannot keep. We do this so that at the end of a single project, the community does not feel like they have been left high and dry. We also try to employ a local worker to liaise with the community while we are out of country.
Project Everest Ventures constantly assesses the viability of conducting projects within communities, focusing on positive impact. If, when your project or month on project is complete, there are other areas where your work can be developed or if the same area has further potential for future projects then other students may return to conduct a project. Through this, both the community that you have helped and future students will benefit directly from your work whilst in country.
