In particular, climate change is likely to exacerbate the frequency and intensity of extreme weather events (e.g., tropical storms, floods, heat waves) and the gradual processes of environmental degradation (e.g., desertification and soil and coastal erosion). Those effects of climate change and their adverse consequences for livelihoods, public health, food security and water availability will have a major impact on human mobility, as one natural response will be to migrate. B. United Nations system and international engagement on migration and climate change 21. While the question of the impact of climate change on migration patterns and the displacement of persons has long been neglected, it has started to receive much needed attention from the international community. 22. In the context of the work of Special Procedures, the former Special Rapporteur on the human rights of migrants, Jorge Bustamante, in his final report to the Human Rights Council in 2011, noted the increasing relevance of climate change and its impact on the movement of peoples and recommended that further study be made on the impacts of environmental and climate change on human mobility (see A/HRC/17/33, paras. 47-62). 23. Other mandate holders have also developed very timely reports dedicated to this issue in relation to their respective mandates, notably the Special Rapporteur on the human rights of internally displaced persons (A/66/285) and the Special Rapporteur on adequate housing as a component of the right to an adequate standard of living, and on the right to non-discrimination in this context (A/64/255). 24. In 2009, the Office of the United Nations High Commissioner for Human Rights (OHCHR) submitted a report to the Human Rights Council in response to its resolution 7/23 on the relationship between climate change and human rights. The report also contained a detailed section focused on the impact of climate change on migration (see A/HRC/10/61, paras. 55-60). 25. Each of those reports contains important definitions, including basic concepts and terminology, especially on mitigation and adaptation, 2 upon which the Special Rapporteur will rely in the present report. Furthermore, the Special Rapporteur will use the term “climate-change-induced migrant” to refer to persons who may migrate in connection with the environmental impacts of climate change. 26. Beyond the work of OHCHR, the United Nations system as a whole is also increasingly focusing on the intersection of climate change and environmental __________________ 1 2 6 Walter Kälin, “Conceptualizing Climate-Induced Displacement”, in Climate Change and Displacement: multidisciplinary perspectives, pp. 81-103, Jane McAdam, ed.
