A/HRC/10/46 page 9 29. Several field presences monitored cases of violations of economic, social and cultural rights. The field presences in Cambodia, Central Asia, Mexico, Nepal, Sudan and Timor-Leste monitored the enjoyment of the right to food, adequate housing, education, health and work. The Human Rights and Transitional Justice Section of the United Nations Integrated Mission in Timor-Leste (UNMIT) designed a monitoring tool to review the enjoyment of the right to food throughout the country, including the distribution of rice subsidies in various districts. On the basis of OHCHR monitoring, the Government of Timor-Leste changed the distribution system for subsidized rice so as to reach the most vulnerable groups which were left out of the distribution scheme. The OHCHR Regional Office in Central Asia has been monitoring the enjoyment of the right to adequate housing in Kazakhstan, Kyrgyzstan and Tajikistan, with a focus on forced evictions and homelessness. In the Sudan, the human rights component of the United Nations Mission in Sudan (UNMIS) continued to monitor and report on forced relocation and evictions related to the construction of two large-scale hydropower dams in the northern Nile valley. OHCHR in Mexico has been monitoring cases of violations of the right to health, the right to education and the right to work. As part of its ongoing work on the right to adequate housing, OHCHR in Cambodia has been monitoring and investigating cases of threats and attacks against community members and civil society actors in relation to land-related activism, as well as trials of individuals advocating on issues related to forced evictions and land. In Nepal, OHCHR monitored cases of caste-based discrimination against particular groups such as the Haliyas and Kamaiyas, including forced evictions and lack of access to safe drinking water, notably from the perspective of access to justice. 30. Research and assessments related to the enjoyment of economic, social and cultural rights were conducted in various countries. In Timor-Leste, the UNMIT Human Rights and Transitional Justice Section launched a report on the right to food in December 2008. The report revised the existing legal framework for the protection of the right to food, along with challenges to its realization, notably in relation to the availability and accessibility of food. The OHCHR Office in Uganda has been carrying out research on housing, land and property restitution in northern Uganda, looking at the existing legal framework related to restitution, as well as aspects of the restitution process in post-conflict northern Uganda. 31. Human rights field presences have also supported processes of legal protection and reform of legislation related to the enjoyment of economic, social and cultural rights. In the former Yugoslav Republic of Macedonia, the Human Rights Adviser provided assistance to the Ministry of Labour and Social Policy in the drafting of a comprehensive anti-discrimination legislation covering notably economic, social and cultural rights. OHCHR-Colombia revised the law modifying the right to strike and the draft law aimed at including the right to water in the Constitution. In addition, the Office also followed up on a number of judicial decisions which impact on the enjoyment of the rights to work, health and social security. In Uganda, OHCHR has been providing comments to the Land Amendment Bill in light of international human rights obligations related to the right to adequate housing. The Uganda Office has also been contributing to revising national legislation on mental health from the perspective of the Convention on the Rights of Persons with Disabilities. OHCHR Office in Mexico participated in the elaboration of a proposal for a constitutional reform on human rights, with a specific chapter on economic, social and cultural rights.
