The stark reality of global climate change today, coupled with the unprecedented rapid pace at which it is occurring, has brought with it several adverse consequences for human security. Unsurprisingly, there is also an increasing realization among scholars and policy makers that climate change is not just an environmental issue, but is predominantly a human security issue. In this interface between climate change and human security, the role of international law has increasingly come under scrutiny, not only in terms of the ability of existing laws in protecting from adverse effects, but also in terms of the possible role of international law in establishing, regulating and successfully implementing appropriate frameworks for global environmental governance. This six weeks online course introduces participants to the current and emerging debates in the linkages between climate change, human security, and international law from a trans-disciplinary perspective. Various dimensions of these linkages including water security, food security, climate induced migration, human rights approaches etc. will be explored. Finally, participants will be invited to discuss and debate the future directions of these linkages. This course is jointly organized by UNU-EHS and UPEACE, and draws on research expertise from both organizations on this topic.
