A/HRC/20/4 Haiti, Nepal and the Occupied Palestinian Territory. In the framework of the Global Protection Cluster, OHCHR contributed to the development of training materials on housing, land and property and protection in natural disasters. 9. Age-related discrimination is a growing concern in many societies around the world. Trends indicate it will become increasingly prevalent as communities age more rapidly than at any other time in history. In December 2010, the General Assembly adopted resolution 65/182, in which it established an open-ended working group on ageing with the purpose of strengthening the protection of the human rights of older persons. The working group is mandated to consider the existing human rights framework, particularly any gaps and how to best address them, including by considering the feasibility of further instruments and measures. Deliberations at the first and second working sessions in 2011 highlighted several obstacles to the enjoyment of economic, social and cultural rights, notably in relation to the rights to social security, the right to an adequate standard of living, including housing and food, and the right to the enjoyment of the highest attainable standard of physical and mental health. 10. During 2011, OHCHR dedicated attention to supporting the Open-Ended Working Group, as part of its Secretariat. OHCHR also contributed to the preparation of the report of the Secretary-General to the General Assembly addressing the human rights of older persons.4 As the report points out, the most critical challenges facing older persons are closely linked to the protection and effective enjoyment of the economic, social and cultural rights. OHCHR will, during the second quarter of 2012, report to the Economic and Social Council on the human rights situation of older persons. 11. In 2012, OHCHR will publish “The Corporate Responsibility to Respect Human Rights: An Interpretive Guide” to assist in the interpretation of the United Nations Guiding Principles on Business and Human Rights. 5 The Guide is not intended to alter the provisions of the Guiding Principles or the expectations that they set for businesses. Its purpose is, rather, to provide additional background information with a view to promoting a more comprehensive understanding of the Guiding Principles. 12. OHCHR released a study entitled “international legal protection of human rights in armed conflict” in 2011 which explains the complementarity between human rights law and international humanitarian law, as well as the respective human rights obligations of national authorities, humanitarian actors and others in times of armed conflict. Most notably, the study focuses considerable attention on economic, social and cultural rights, their application and the limited circumstances under which derogations are permissible. 13. Finally, OHCHR continued its efforts to integrate economic, social and cultural rights into its human rights monitoring, the documentation of violations and into its reporting functions. This includes the production of a new chapter of the OHCHR Manual on Human Rights Monitoring (“Monitoring economic, social and cultural rights”), the development of a comprehensive glossary of human rights and international humanitarian law violations, and the organization of a specialized course and/or specific sessions on monitoring economic, social and cultural rights.
