The Herdsmen are economically significant in Africa sub-region but climate change has forced them through the Northeast geopolitical zone border with Chad into Nigeria to become a national security threat. The central aim of this study is to systematically examine whether there are extant policy responses towards revitalizing and sustaining the Lake itself. To achieve this, three questions were raised: What is the geographical and socioeconomic significance of Lake Chad? What is the nexus between the change in the Lake Climate and Herdsmen trans-border migration into Nigeria? Are there extant policy responses directed towards recharging and sustaining the Lake? This study adopted qualitative technique which relied on secondary sources. Content analytical methodology was adopted and the pull-push migration theory underpinned this study. This study found that geographical and socioeconomically, the Lake Chad is an important transnational and trans-boundary freshwater resources in the world, located between African countries sharing boundary with Chad, a source of freshwater and grazing field for Herdsmen and their herds as well as source of irrigation for agricultural activities in the region; that the shrinking of the Lake led to scarcity of freshwater and grazing field forcing the Herdsmen to migrate into Nigeria as alternative for survival; that there are existing policy responses towards addressing the challenges of climate change in the Lake Chad but there have not been any direct policy response towards revitalizing and sustaining the Lake itself. Hence, the paper recommended the need for countries at the cradle of the Lake to strengthen collaboration under the Lake Chad Basin Commission (LCBC) with International Partners to formulate policy, provide financial and technical support required to achieve the revitalization and sustainability of the Lake.
