A/RES/58/149 21. Calls upon the Office of the High Commissioner, the African Union, subregional organizations and all African States, in conjunction with agencies of the United Nations system, intergovernmental and non-governmental organizations and the international community, to strengthen and revitalize existing partnerships and forge new ones in support of the international refugee protection system; 22. Calls upon the Office of the High Commissioner, the international community and other concerned entities to intensify their support to African Governments through appropriate capacity-building activities, including training of relevant officers, disseminating information about refugee instruments and principles, providing financial, technical and advisory services to accelerate the enactment or amendment and implementation of legislation relating to refugees, strengthening emergency response and enhancing capacities for the coordination of humanitarian activities; 23. Reaffirms the right of return and the principle of voluntary repatriation, appeals to countries of origin and countries of asylum to create conditions that are conducive to voluntary repatriation, and recognizes that, while voluntary repatriation remains the pre-eminent solution, local integration and third-country resettlement, where appropriate and feasible, are also viable options for dealing with the situation of African refugees who, owing to prevailing circumstances in their respective countries of origin, are unable to return home; 24. Notes with satisfaction the voluntary return of millions of refugees to their homelands following the successful repatriation and reintegration operations carried out by the Office of the High Commissioner with the cooperation and collaboration of countries hosting refugees and countries of origin, and welcomes the efforts under way, in cooperation with other United Nations agencies and development actors, to promote a framework for durable solutions, particularly in protracted refugee situations, including the “4Rs” approach (repatriation, reintegration, rehabilitation and reconstruction) to sustainable return; 25. Appeals to the international community to respond positively, in the spirit of solidarity and burden-sharing, to the third-country resettlement requests of African refugees, and notes with appreciation that some African countries have offered resettlement places for refugees; 26. Calls upon the international donor community to provide financial and material assistance that allows for the implementation of community-based development programmes that benefit both refugees and host communities, as appropriate, in agreement with host countries and consistent with humanitarian objectives; 27. Welcomes the programmes carried out by the Office of the High Commissioner with host Governments, the United Nations, non-governmental organizations and the international community to address the environmental and socio-economic impact of refugee populations; 28. Calls upon the international donor community to provide material and financial assistance for the implementation of programmes intended for the rehabilitation of the environment and infrastructure affected by refugees in countries of asylum; 29. Expresses its concern about the long stay of refugees in certain African countries, and calls upon the Office of the High Commissioner to keep its programmes under review, in conformity with its mandate in the host countries, taking into account the increasing needs of refugees; 6
