the red crescent has an office here. they have an office that deals with local development and a separate one for the international work. from what i have heard you should avoid the local one.

there is also Reach Out to Asia (part of Qatar Foundation), but they don't have a great reputation as far as employers go. depending on what you are looking for you might find it frustrating. they are great at fund raising but from what i have heard they then send the money to local charities who do the ground work.

also part of Qatar Foundation is SDC (Social Development Center). I believe that this center deals with local development.
