The Bureau of Population, Refugees and Migration at the US State Department has announced a funding opportunity in Sudan for projects benefiting Southern Sudanese Refugee Returnees and receiving communities and NGO programs in Sudan benefiting Congolese and CAR Refugees.
Current Funding Priorities for Refugee Reintegration:
(b) Proposals should comment on the point of refuge (i.e., refugee camps in Uganda, Kenya, Ethiopia, or elsewhere) of targeted returnee beneficiaries and should address the needs of those who have returned since 2009.
(c) Proposed activities may also target areas of potential return, with the inclusion of an analysis of the reasonable prospect for returns to the targeted geographic area. Priority will be given to Eastern Equatoria, Upper Nile, and Jonglei States, given the provenance of the remaining southern Sudanese refugees.
