A/HRC/39/37 activists and human rights defenders from the countries in question. They benefited from direct engagement with Committee members in public and private settings. IV. Conclusions 107. During the reporting period, indigenous peoples in many parts of the world continued to face numerous significant human rights challenges, as highlighted by United Nations human rights mechanisms, which included intimidation and reprisals against those cooperating with the United Nations. In order to address these human rights challenges, OHCHR carried out a range of country and regional activities to facilitate constructive dialogue and engagement between indigenous peoples, national authorities, public officials and, when relevant, the private sector. 108. The lack of or insufficient access to justice for indigenous peoples in State legal systems, along with the lack of statutory recognition and adequate protection of indigenous land rights, contributed to the challenges experienced by indigenous peoples worldwide. OHCHR assisted States in improving indigenous peoples’ access to legal remedies so that indigenous peoples could better benefit from national legal systems, advocate for the recognition of their own justice systems and participate in the development and implementation of domestic policies and legislation to protect their rights. 109. OHCHR also supported States in strengthening their capacity to protect indigenous human rights defenders and to fulfil their duty to consult and cooperate with indigenous peoples to obtain their free, prior and informed consent before adopting and implementing measures that may affect them. Strengthening prevention of, and addressing, intimidation and reprisals against those who cooperate with the United Nations has also been a priority of OHCHR. 110. OHCHR continued to support States, national human rights institutions and civil society in empowering individuals and communities to monitor deteriorating situations, and establish systems to prevent and monitor conflicts, particularly regarding their lands and resources. 111. Recognizing that the 2030 Agenda for Sustainable Development puts the principles of equality and non-discrimination at its centre, OHCHR supported the implementation of the Sustainable Development Goals and the associated targets relevant to indigenous peoples. The collection of disaggregated data continues to be essential for a comprehensive assessment of the extent and range of the challenges confronting indigenous peoples today, and it remains, worldwide, largely insufficient. 112. As is evidenced in the present report, significantly enhanced efforts are needed in order for States to ensure effectively the full and equal enjoyment of rights for all indigenous peoples, through domestic laws, policies and strategies in line with the United Nations Declaration on the Rights of Indigenous Peoples, relevant human rights obligations and the outcome document of the World Conference on Indigenous Peoples. 17
