A/66/288 of civil society working on issues of relevance to indigenous peoples. The visits take place with the consent and cooperation of the respective Government. 47. The Special Rapporteur has conducted visits to and reported on Brazil (A/HRC/12/34/Add.2); Nepal (A/HRC/12/34/Add.3); Botswana (A/HRC/15/37/Add.2); Australia (A/HRC/15/37/Add.4); the Russian Federation (A/HRC/15/37/Add.5); the Sápmi region (the traditional territory of the Sami people) in Norway, Sweden and Finland (A/HRC/18/35/Add.2); the Congo (A/HRC/18/35/Add.5); and New Caledonia (France) (A/HRC/18/35/Add.6). He has also conducted follow-up visits to Chile (A/HRC/12/34/Add.6), Colombia (A/HRC/15/37.Add.3) and New Zealand (A/HRC/18/35/Add.4) to evaluate the progress made in those countries in implementing the recommendations made by the Special Rapporteur’s predecessor. 48. In 2011, the Special Rapporteur will visit Argentina and, early in 2012, the United States. He has also received invitations from the Governments of Panama and El Salvador to evaluate the situations of indigenous peoples in those countries, and welcomes those invitations. The Special Rapporteur has outstanding requests to visit Bangladesh, Cambodia, Malaysia, Indonesia and Papua New Guinea, which he hopes will be considered favourably. C. Specific cases of alleged human rights violations 49. Another principal area of the Special Rapporteur’s work involves responding, on an ongoing basis, to allegations of human rights violations in specific cases. Summaries of letters sent by the Special Rapporteur communicating his concerns over particular situations and responses received from Governments, together with the Special Rapporteur’s observations and recommendations, are included in his communications to and from Governments (A/HRC/18/35/Add.1, A/HRC/15/37/Add.1 and A/HRC/12/26/Add.1). 50. The Special Rapporteur has received information about cases of alleged human rights violations in countries on every continent and, in response to them, has sent numerous communications to Governments about these situations. Complaints received have related to common issues that affect indigenous peoples throughout the world, including the denial of the rights of indigenous peoples to their lands, territories and natural resources; violations of the right to consultation and to free, prior and informed consent, especially with regard to natural resource extraction or the eviction of indigenous communities; threats or violence against indigenous individuals and communities, including human rights defenders; concerns about constitutional or legislative reforms in indigenous subject matter; issues related to the recognition of indigenous justice systems; and the situation of indigenous peoples in isolation. 51. Given the limited resources available, it is impossible for the Special Rapporteur to respond to every case that comes to his attention. However, he frequently acts on detailed and credible information that presents a serious situation falling within his mandate in which intervention has a reasonable chance of having a positive impact, either by drawing needed attention to the situation or by prompting Government authorities or other actors to take corrective action. Alternatively, he may take action where the situation is representative of, or connected to, a broader pattern of human rights violations against indigenous peoples. He has responded to allegations of human rights violations from a wide range of regions and countries. 10 11-44942
