A comment on my Farming in Guatemala post led me to Agros International , and eventually to Global Giving. I was impressed with both of these organizations, and decided to use Rambling Traveler to bring them to the attention of others.
Global Giving allows you to make financial donations of any size to specific grassroots projects listed on their site. There are projects in 60 countries, some focusing on education, others on health care, economic development, and the environment. You can choose projects based on location or focus, depending on your special interests. All donations are tax deductible. The website is very appealing and easy to navigate. (For those interested in site design, why this site works so well was explained in a nice review that highlights the changes they recently made.)
A good description for Agros International comes from their website: "committed to breaking the cycle of poverty for rural families in Central America and Mexico by enabling landless communities to achieve land ownership and economic stability." This site is also easy to use, with stories about the organization and the people they help. You can make donations directly through the site, or through the Global Giving site where Agros has several projects listed.
If you have had experiences with either group in the past, please tell us about it in the comments section below.
