A/HRC/42/19 7. In that context, the OHCHR office in Colombia provided training to indigenous human rights defenders on the Sustainable Development Goals, the 2030 Agenda for Sustainable Development and the right to a healthy environment in Magdalena Medio. To ensure the participation of indigenous peoples in the self-identification campaigns launched by the Government of Guatemala ahead of the national census, the OHCHR office in Guatemala facilitated meetings between indigenous representatives and the national authorities concerned with the census. Focusing on the relevance of the Sustainable Development Goals to the rights of indigenous peoples, the OHCHR office in Honduras facilitated a workshop in January 2019 on human rights and the implementation of the 2030 Agenda. 8. During the period under review, the OHCHR office in Mexico promoted the Sustainable Development Goals in the technical assistance provided to the authorities and in media communications, emphasizing how the principle of “leave no one behind” applies to indigenous communities. 9. The Special Rapporteur on the rights of indigenous peoples participated in the 2018 high-level political forum on sustainable development, including being the lead discussant during the panel on “leaving no one behind” and engaging in the voluntary national reviews. In her report to the General Assembly in 2018, the Special Rapporteur looked at how the self-governance of indigenous peoples could contribute to achieving sustainable development for them, including an analysis of the linkages between the recommendations of the Special Rapporteurs on indigenous peoples since 2005 and the targets of the Sustainable Development Goals (A/73/176). 10. The Special Rapporteur on the right to development reported that some States considered indigenous peoples as actors engaged in the enhanced implementation of the Sustainable Development Goals, including in the management of natural resources, through participation in and dialogue with the public services (A/HRC/39/51, para 50). B. Free prior and informed consent and the consultative mechanisms, including in the context of business and the extractive industries 11. The lack of meaningful implementation of the principle of the free, prior and informed consent of indigenous peoples in development projects and plans that may affect them continued to undermine the protection and promotion of their rights during the period under review. 12. In the context of the ongoing work of the OHCHR office in Colombia on supporting the drafting of consultation protocols for indigenous peoples, technical advice and support was provided to 15 indigenous communities of the Putumayo region. As a result, the process of formulating a protocol for the relations of indigenous peoples with third parties moved forward, anchored in the principle of free prior and informed consent. The OHCHR office also offered technical support to different stakeholders on the rights of indigenous peoples and environmental issues, including in the landmark ruling that declared the Amazon subject to rights and orders measures to counter deforestation, recommending that the State guarantee the right of affected communities to participation and consultation. The office also provided technical support and guidance to Nasa indigenous communities in the Putumayo region, to State authorities and to an oil company on international norms and standards on the right to a healthy environment, the right to participation and other human rights affected by environmental damage. 13. The OHCHR office in Guatemala monitored the implementation of three judgments of the Constitutional Court, in which it ordered the State to carry out consultations with indigenous peoples in the Santa Rosa region in view of the negative impacts of the exploitation of natural resources on the rights of indigenous peoples. In October 2018, the OHCHR office supported the organization of meetings between members of the Xinca parliament and international experts regarding measures for implementation of the judgment of the Constitutional Court in the case of the San Rafael mine. In the judgment, the Court had ordered the State to consult with the affected Xinca people. Also in 2018, two draft laws on consultation with indigenous peoples were presented to the Congress in 3
