A/HRC/43/28 discrimination against specific communities and groups of people, divided along lines of gender, race, ethnicity, religion or other status.1 7. The present report considers the work of human rights mechanisms and OHCHR in strengthening partnerships to develop practical approaches to implement the commitment to leave no one behind and the related normative human rights framework. Pursuant to its resolution 37/24, the Human Rights Council held two multi-stakeholder intersessional meetings for dialogue and cooperation on human rights and the 2030 Agenda, on 16 January and 3 December 2019. Those meetings illustrated the synergies and linkages between human rights and the Sustainable Development Goals, particularly at national level. They provided an opportunity for stakeholders to share and exchange good practices and challenges on how integrated approaches to implementing the Sustainable Development Goals and realizing human rights contributed to the fulfilment of the 2030 Agenda. 8. Some illustrations of these practical approaches to leaving no one behind can be found in the work of OHCHR during the past year. At the country level, OHCHR continued monitoring the situation of the ethnic Vietnamese communities living in floating villages around the Tonle Sap lake. In Kampong Chhnang Province, the provincial authorities planned to relocate 10,000 people living in floating villages, including nationals of Cambodia and members of the ethnic Vietnamese communities. However, the latter were relocated to areas in which basic services were not available, including water and electricity, and they were resettled on land that was not close to the lake, putting their livelihoods, as fishing communities, at risk. OHCHR and the Special Rapporteur on the situation of human rights in Cambodia engaged in a constructive dialogue with the provincial authorities to find suitable solutions for them, leading to a temporary suspension of their relocation, until basic services were made available. 9. In Colombia, the month of March was marked by widespread protests by, among others, Afro-Colombians. They were closely monitored by OHCHR. Long-standing social grievances tied to the lack of land rights, delays in the implementation of the peace accord and the killing of human rights defenders were some of the issues that motivated the protests. The collective territories of Afro-Colombian communities fulfil a social and ecological function fundamental to the life of these communities. Nonetheless, access to collective land rights, especially for Afro-Colombian communities, remains an obstacle. 10. At the conclusion of its visit to Argentina in March, the Working Group of Experts on People of African Descent stated that Argentina should come to terms with the reality that people of African descent were a vulnerable group deserving special measures as they were not fully able to enjoy their economic, social and cultural rights. 11. In July, the Special Rapporteur on contemporary forms of racism, racial discrimination, xenophobia and related intolerance expressed concern that the extraction of natural resources routinely inflicted acute human rights violations on minorities and other marginalized groups. She noted that powerful States, including those that had yet fully to reckon with their colonial extractivism legacies, must commit to undoing the structures of subordination and inequality that persisted in the extractive economy.2 III.
