A/HRC/4/32/Add.2 page 22 the impact of the internal conflict in Colombia, illicit drug production and trafficking activities, environmental degradation, the influx of indigenous refugees from Colombia and the situation of violence and insecurity in the area. Concessions granted to oil and mining companies must be reviewed. The State must shape public policies aimed at protecting the various sectors, peoples and communities who live on the northern border, with their full participation, including the right to free, prior and informed consultation. 88. The Special Rapporteur recommends that Ecuador implement measures (including those under CITES) to ensure rigorous control of timber species in indigenous lands, in particular those inhabited by peoples in voluntary isolation, and coordinate actions with the various State authorities to ensure effective protection in the trade and export of all species. C. Consultation, participation and recognition 89. The Special Rapporteur recommends that all Ecuadorian authorities comply with the provisions of the Inter-American Commission on Human Rights and the Inter-American Court of Human Rights in the Sarayaku case, and more specifically, that the State Procurator-General unconditionally uphold the unimpeded protection of the Sarayaku community, including its rights, its land ownership and the life and physical integrity of all of its members. 90. The State must recognize the ancestral lands of the Shuar and other Amazonian peoples who have yet to receive this recognition. D. Security, social protest and justice-related activities 91. The Special Rapporteur recommends that the armed forces abstain from concluding service provision contracts with oil companies that could damage the rights of the indigenous communities in whose territories they are operating. 92. The Special Rapporteur recommends that Ecuador carry out a thoroughgoing investigation into accusations of abuse and violence against members of indigenous communities committed by some elements of the armed forces, under the auspices of the said contracts, and that those responsible are punished. It is further recommended that any inappropriate arrangement between the aforementioned companies and the armed forces, which has its aim to protect the private economic interests of the companies and could damage the legitimate rights of the indigenous peoples and communities in the regions affected by the activities of the oil companies, be prevented. 93. Following the disproportionate response of the authorities to the social protest mounted by indigenous organizations during the state of emergency against the free trade treaty, the Special Rapporteur recommends that the Government carry out a thoroughgoing investigation into the events and punish, among others, those who abused the human rights of the indigenous demonstrators.
