In October 2015, OHCHR started a pilot project to support discussions and negotiations between indigenous Bunong communities from the village of Busra in Mondulkiri Province affected by an economic land concession and the private company to which the land concession had been granted. As of April 2016, compensation agreements have been made concerning one sacred site and clear and timebound commitments were made by the company to review over 100 pending land claims.

The regional office for Southern Africa continued to play an active role in many initiatives related to the promotion of the rights of indigenous peoples. The South African Human Rights Commission held national investigative hearings on human rights violations among Khoisan communities in November and December 2015 and April 2016. The national hearings were convened in several provinces of South Africa on the basis of complaints received by the Commission from various Khoisan communities (Khoi, San, Nama, Griqua and Koranna) regarding access to basic services, land and the constitutionality of indigenous groups in South Africa. The outcome of the hearings will be a report with concrete recommendations and possibly also action plans on the issue. 28.

In 2015, the office in Guatemala developed, in coordination with the national human rights institution, a methodology to observe the implementation of the Government’s strategy to combat malnutrition, including among indigenous peoples, which are among the most affected by malnutrition in the country.
