A/HRC/4/38 page 21 80. In Colombia, the Brookings-Bern Project is working with a group of Colombian legal scholars to develop a study on Colombian jurisprudence, in particular the jurisprudence of the Constitutional Court. The study is focusing on challenges for the implementation of the courts’ decisions and an assessment of their impact. The study will be edited for publication and translated into English to make lessons learned in Colombia more widely-available. 81. Another focus of research is the relationship between peace issues and internal displacement. As mentioned above, studies have been commissioned to explore whether and how to integrate the IDP issue and IDPs themselves into peace processes and peacebuilding efforts. An expert workshop to discuss the first draft of the report on peace processes took place at the Brookings Institution in October 2006 and the final report is scheduled for 2007. A draft of a report by a consultant on how the Peacebuilding Commission can best incorporate IDP and refugee issues into its work was discussed by an expert workshop at the Brookings Institution in December 2006. It served as basis for the above-mentioned submission to the Peacebuilding Commission. VI. CONCLUSIONS AND RECOMMENDATIONS 82. Responding to the protection needs of internally displaced persons (IDPs) is one of the main challenges of today’s world. For his part, the Representative of the Secretary-General for human rights of internally displaced persons strongly believes that, in carrying out his mandate, he contributes to the efforts that are being undertaken to meet these challenges. In particular, he is of the view that the ongoing development and clarification of the conceptual framework is essential in helping those who directly assist IDPs at the national level. Recalling that States have the ultimate responsibility to protect the human rights of IDPs living on their territory, the Representative continued, during the period under review, to engage in constructive dialogues with Governments with the goal of enhancing the protection of this particularly vulnerable group. In the same line, he also continued his efforts to mainstream the human rights of IDPs in the United Nations system and to advocate for the human rights of IDPs on the global level. Much still needs to be done in order to respond effectively, comprehensively and in a timely manner to the needs of IDPs worldwide, but the Representative is encouraged by the steps that have been taken by many governments, by the international community and the relentless efforts of the civil society. 83. With respect to the countries visited, the Representative: (a) Encourages the Governments to implement the recommendations made in his country-specific reports and stands ready to offer ongoing advice and technical assistance; (b) Invites national human rights institutions and civil society to follow these efforts, to monitor implementation of his recommendations, and to provide feedback to the relevant institutions on human rights issues associated with displacement.
