A/HRC/14/33 preventive visits, to Cambodia, Honduras and Paraguay. In such endeavours, the SPT adopted an integral approach, considering both civil and political and economic, social and cultural rights. The conditions that the SPT monitors during its visits encompass the enjoyment of economic, social and cultural rights by persons deprived of their liberty. Reports and recommendations of the SPT refer to, inter alia, the enjoyment of the right to health, the right to food, the right to work, the right to education and other economic, social and cultural rights. Attention was particularly paid to persons in vulnerable situations, such as children, persons with disabilities, indigenous peoples and people of African descent, women, and migrants. III. Activities of special procedures 21. The independent expert on the issue of human rights obligations related to access to safe drinking water and sanitation, Catarina de Albuquerque, devoted 2009 to examining the issue of human rights obligations related to access to sanitation, recognizing that this topic has been relatively neglected if compared with the associated area of water. The report reviews the integral relationship between sanitation and multiple other civil, cultural, economic, political and social rights, and concludes that analysing sanitation only through the lens of other human rights is insufficient. She notes a trend towards recognizing sanitation as a distinct right, and supports this trend because of its fundamental connection to human dignity. She also embarked on a process of collecting good practices, beginning by establishing criteria for the identification of such practices from a human rights perspective. She undertook fact-finding missions to Costa Rica and Egypt, as well as a joint mission to Bangladesh with the independent expert on the question of human rights and extreme poverty. 22. In March 2009, the Human Rights Council established the mandate of the independent expert in the field of cultural rights. In October 2009, the Council appointed the first independent expert on cultural rights, Farida Shaheed. The mandate requires her to identify best practices in the promotion and protection of cultural rights, to identify obstacles to the enjoyment of cultural rights, to work with States to foster the adoption of measures to promote and protect cultural rights, and to study the relationship between cultural rights and cultural diversity. 23. In 2009, the Special Rapporteur on the right to food, Olivier De Schutter, continued working on the impact of the global food prices crisis, notably by participating in the General Assembly thematic dialogue on the global food crisis and the right to food in April 2009. He also participated in the reform of the FAO Committee on World Food Security. The Special Rapporteur examined the impact of trade policies and agriculture policies on the realization of the right to food, and advocated for a new approach and renewed investment in agriculture in Africa. He also studied the phenomenon of large-scale land acquisitions and leases, calling on all stakeholders to consider their potential effect on the realization of the right to food and to improve the security of tenure of smallholder farmers. He set forth guiding principles on large-scale land acquisitions and leases. In June 2009, the Special Rapporteur convened a conference in Berlin of representatives of agricultural business corporations to discuss their role in the protection of the right to food. He also conducted two missions to Benin and Nicaragua and two follow-up missions to Guatemala and Brazil. 24. The Special Rapporteur on the right of everyone to the enjoyment of the highest attainable standard of physical and mental health, Anand Grover, presented his annual report to the Human Rights Council in June 2009. The report considered the relationship between the right to the highest attainable standard of health and intellectual property rights, especially with regard to access to medicines, as well as impact of the TRIPS 6 GE.10-12597
