Hi Ida,
Thanks for posing these questions. As the owner of a travel planning company with a focus on voluntourism, I frequently ponder these questions myself.
I don't think there's a one-size-fits-all answer, even when intentions of the voluntourists are good. Determining which causes to support, and what to "fix" is extremely subjective. I've made initial contact with some organizations to support after seeing the positive results of their work, and I'm also open to organizations approaching me first, and requesting support through a voluntourism program. (I'm certainly aware that some individuals or communities do not have an organized voice or way to contact anyone about their plight.)
There are cases in which communities are "content" living in conditions many would find deplorable and are happy to simply share their experiences with visitors, not wanting to be influenced by outside forces that would dilute the aspects of their culture they themselves find most appealing (and are not harmful by anyone's standards). Clearly when a community's health is compromised or basic needs are not being met, we should respond with help, so I'm not considering those scenarios here.
We'd all like to think that the best approach is to assist in such a way that will enable those in need to become (more) self-sufficient and not encourage dependency since dependent relationships often become rife with corruption and manipulation on both sides. Too often the people requiring assistance are not managing their own solutions, they are not administering their own aid because of a belief that they are incapable of doing so. We all know the "teach a man to fish" saying....and I think it certainly applies here.
I encourage voluntourists to see the non-monetary riches, the intangibles that already exist, having nothing to do with anyone's financial or on-the-ground support. There should never be an assumption that someone who doesn't have the latest and greatest in technology, or who isn't wearing the latest designer fashions, or living in a tony neighborhood is lacking in all facets of his or her life. There often exists in these communities peace, pride, confidence, humility, intellect, and understanding that far surpasses anything material wealth can bring. There's definitely a belief out there that the only ones on the receiving end with voluntourism programs are the poor or socio-economically challenged. However, I know from first-hand experience that there is as much for the voluntourist to receive as they are giving. My personal best voluntour experiences have resulted in continued relationships with new friends around the world who inspire me with their determination and will in the face of lack and tragedy. I think my clients would agree, and say that a few hours, days or weeks spent helping to build a home, read to a child, or participate in a rally for a cause have been some of the most rewarding experiences of their lives because of the unexpected changes within themselves they felt during and after voluntouring.
I have also seen instances where voluntourists' ideas about what's right and wrong, and their lack of understanding about long-term cultural impacts have angered communities and superiority/inferiority issues arise in the name of modernization. Generations become divided, and the chasm leads to an opportunity for that manipulation I spoke of earlier to breed.
What makes voluntourism work is respect, mutual appreciation and understanding. Voluntour programs should foster a two-way exchange so that everyone benefits from giving and receiving. There should be face-to-face interaction and a willingness to listen and understand the truest desires of all parties to improve the chances of doing more good than harm. Voluntourism can result in successful development, but a genuine desire for positive change in the eyes of the beneficiaries has to outweigh any ulterior motives, no matter how harmless they may seem to be.
