A/66/288 52. The Special Rapporteur aims to engage actively with States, indigenous peoples and others to closely monitor and evaluate situations, identify underlying causes of immediate problems, promote specific action that builds on advances already made and make recommendations that are practical, founded on available knowledge and in accordance with relevant human rights standards. 53. Therefore, for some cases examined, the Special Rapporteur has developed detailed observations and recommendations that he has communicated to Governments, regarding the action which, in his view, States and, as appropriate, other interested parties should take to address those situations, within the framework of the relevant international standards. He will continue to engage with States about these specific situations and hopes that the dialogue to date has been useful for the Governments and indigenous peoples concerned. 54. Certain communications received by the Special Rapporteur contain allegations of specific violations of human rights of indigenous peoples that warrant deeper analysis. For these matters, he has carried out site visits to countries as part of his examination of those cases. As a result of the visits, he has issued detailed observations with analyses and recommendations, in the hope that they will be of use to the Governments and indigenous peoples concerned in their efforts to address the problems raised. 55. In that connection, in April 2011 the Special Rapporteur travelled to Costa Rica to examine the situation of indigenous peoples affected by the El Diquís hydroelectric project. The Special Rapporteur provided the Government and indigenous stakeholders with his observations and recommendations on the situation (A/HRC/18/35/Add.8). 56. Similarly, in June 2010, the Special Rapporteur visited Guatemala to discuss the implementation of the principles of consultation with indigenous peoples in the country, particularly in relation to extractive industries, with a special focus on the situation of indigenous peoples affected by the Marlin mine in the municipalities of San Miguel Ixtuhuacán and Sipacapa (A/HRC/18/35/Add.3). 57. In February 2009, the Special Rapporteur travelled to Panama to examine the situation of the indigenous communities affected by the construction of a hydroelectric project on the Changuinola River in Panama (A/HRC/12/34/Add.5). In June 2009, he went to Peru immediately following the confrontations between indigenous peoples and the police in Bagua, Peru, in order to examine first hand the human rights issues (A/HRC/12/34/Add.8). 58. During his visit to Australia in August 2009, the Special Rapporteur followed up on earlier communications concerning the effects on indigenous rights of the Northern Territory Emergency Response of the Government of Australia. He prepared a special report containing his observations on that matter, which was annexed to his report on the situation of indigenous peoples in Australia (A/HRC/15/37/Add.4, appendix B.) 59. The Special Rapporteur believes that his ability to intervene rapidly in situations of crisis involving indigenous peoples, such as the situation of Bagua in Peru, has proved to be an effective use of his mandate, allowing him to play a key role in the resolution, mitigation or improvement of situations of crisis involving indigenous peoples. 11-44942 11
