The ‘Network of Networks’ – an informal coalition of harm reduction networks from around the world – came together to create this brochure for a meeting of key harm reduction donor organisations in the Netherlands. The brochure makes recommendations to donors around the issues facing harm reduction advocates: that the funding for harm reduction must be proportionate to the impact that drug use has on the global HIV epidemic; that capacity needs to be increased in order to deliver the necessary services; and that civil society capacity also needs to be increased in terms of advocacy and networking.
