A Want to explore new cultures, meet new people and do something worthwhile at the same time? You can do all the three with Global Development Association ( GDA ) .Whatever stage of life you’re at, wherever you go and whatever project you do in GDA, you’ll create positive changes in a poor and remote community ( 社区 ) . We work with volunteers of all ages and backgrounds. Most of our volunteers are aged 17-24. Now we need volunteer managers aged 25-75. They are extremely important in the safe and effective running of our programmes. We have such roles as project managers, mountain leaders, and communication officers. Depending on which role you choose, you could help to increase a community’s access to safe drinking water, or help to protect valuable local cultures. You might also design an adventure challenge to train young volunteers. Not only will you help our young volunteers to develop personally, you’ll also learn new skills and increase your cultural awareness. You may have chances to meet new people who’ll become your lifelong friends. This summer we have both 4-week and 7-week programmes : Country Schedule 4-week programmes 7-week programmes Algeria 5 Jul.—1 Aug. 20 Jun. —7 Aug. Egypt 24 Jul.—20 Aug. 19 Jun.—6 Aug. Kenya 20 Jul.—16 Aug. 18 Jun.—5 Aug. South Africa 2 Aug.—29 Aug. 15 Jun.—2 Aug. GDA ensures that volunteers work with community members and local project partners where our help is needed. All our projects aim to promote the development of poor and remote communities. There is no other chance like a GDA programme. Join us as a volunteer manager to develop your own skills while bringing benefits to the communities.
