You can find links to all the organisations we have worked with on their specific project page. Those and others that are definitely keen on volunteer help are listed below. This could vary between single, regular work days, internships, or actually full time (voluntary) roles within the organisations.
Please note that EOCA has not vetted the opportunities offered here; it is your responsibility to check what is being offered against your requirements and discuss them directly with the organisation. Please also check travel advice from your local government / foreigh office as EOCA cannot be held responsible for your safely or well-being.
