ARASA is the only regional organisation that is structured in the form of a partnership of country-based civil society organisations working together to promote human rights and health in the context of sexual and reproductive health and rights (SRHR), HIV and TB in southern and east Africa. The ARASA partners are those 100 national and regional organisations from 18 countries in southern and east Africa (Angola, Botswana, Comoros, Democratic Republic of Congo, Kenya, Lesotho, Madagascar, Malawi, Mauritius, Mozambique, Namibia, Seychelles, South Africa, Swaziland, Tanzania, Uganda, Zambia and Zimbabwe), who have formally applied to join the partnership and were formally welcomed to the partnership. The ARASA partners benefit from capacity strengthening opportunities; networking with other like minded organisations; solidarity for advocacy; exposure to regional and international platforms; and access to catalytic funding for innovative projects to promote human rights in the context of HIV and TB amongst others.
