A/HRC/7/58 page 12 reduction strategies. In December, a regional workshop on the justiciability of economic, social and cultural rights was organized and hosted by OHCHR-Chile in partnership with the Economic Commission for Latin America and the Caribbean. B. Enhanced human rights leadership 37. The Strategic Management Plan for the period 2006-2007 emphasizes the leading role the High Commissioner plays, through greater interaction with relevant United Nations bodies and actors, in identifying and analysing human rights problems and proposing solutions to close implementation gaps. To fulfil this role, the Office has taken on board, as priority areas, the work on economic, social and cultural rights, with a focus on legal protection and advocacy, the creation of a women and gender unit and the strengthening of thematic expertise in a number of areas, such as HIV/AIDS, indicators, the right to development and the rights of minorities and internally displaced persons. The Plan also highlights the leading role that the High Commissioner plays in efforts to advance poverty reduction and the Millennium Development Goals. 38. In 2007, pursuant to Human Rights Council decision 2/104, OHCHR submitted a study on human rights and access to water and sanitation. In the study, OHCHR reviewed international human rights obligations related to the provision of safe drinking water and sanitation, discussing their scope and content, nature and monitoring, and pointed to areas needing further elaboration. The study ended with conclusions and recommendations to further strengthen and implement human rights obligations in relation to those areas, including a recommendation that access to safe drinking water and sanitation be considered a human right. 39. As part of its leadership activities, OHCHR has also analysed the human rights dimensions of climate change, an issue of central concern for the international community in 2007. While past analyses of climate change have traditionally focused on its economic and environmental repercussions, human rights norms and standards provide a framework to consider its human dimension, and to shed light on the impact it could have for present and future generations. The preparation of a background document and the support for the Deputy High Commissioner’s attendance to the Bali Conference in December 2007 helped to provide an overview of the human rights dimension of climate change, while leading the way into much needed debate on the measures that the international community need to take. 40. In her report to the Economic and Social Council (E/2007/82), the High Commissioner focused on the concept of “progressive realization”, exploring its meaning and how the treaties allow for gradual realization over time of economic, social and cultural rights while imposing obligations requiring immediate implementation by States parties. In the report, the High Commissioner also discussed some of the issues arising from the practical implementation of obligations subject to progressive realization, commenting on measures and national strategies to move towards progressive achievement of these rights. The essay by the High Commissioner “Economic and social justice for societies in transition”, based on her speech of 25 October 2006 at the Second Annual Transitional Justice Lecture hosted by the New York University School of Law Center for Human Rights and Global Justice and the International Center for Transitional Justice, was in the same vein. By producing a series of such reports and essays, the Office aims at deepening the conceptual understanding of these rights and at providing tools for their better implementation.
