In Africa, owing to a lifestyle that is culturally and collectively dependent on land and its natural resources, indigenous peoples are adversely affected by climate change. This is despite the fact that they contribute least to its cause. While this situation requires the protection of indigenous peoples’ land tenure and use, this is generally not yet the reality in the domestic laws of states in Africa. Premised on four propositions, this article makes a case for a regional policy to safeguard indigenous peoples’ land tenure and use in the light of climate change challenge in Africa. In the main, the propositions are: the indigenous peoples have a distinctive perception of land tenure and use relevant for adaptation and mitigation purposes; the land tenure and use is adversely affected by climate change; there is weak protection of indigenous peoples’ land tenure and use under the national and international climate change response frameworks, particularly the National Adaptation Programmes Plan of Action (napa) documentation as well as land-related Clean Development Mechanism (cdm) and redd+ mitigation initiatives; and there are emerging regional activities with the potential to crystallise into a statement of policy. The proposed policy which should embody detailed normative and institutional safeguards on land tenure and use, the article recommends, can be initiated by the African Ministerial Conference on the Environment (amcen) and the African Commission on Human and Peoples’ Rights (African Commission) for the protection of indigenous peoples facing the adverse impact of climate change in Africa.

The Impact

Abstract Following recent findings, the interaction between resolved (Rossby) wave drag and parameterized orographic gravity wave drag (OGWD) is investigated, in terms of their driving of the Brewer–Dobson circulation (BDC), in a comprehensive climate model. To this end, the parameter that effectively determines the strength of OGWD in present-day and doubled CO2 simulations is varied. The authors focus on the Northern Hemisphere during winter when the largest response of the BDC to climate change is predicted to occur. It is found that increases in OGWD are to a remarkable degree compensated by a reduction in midlatitude resolved wave drag, thereby reducing the impact of changes in OGWD on the BDC. This compensation is also found for the response to climate change: changes in the OGWD contribution to the BDC response to climate change are compensated by opposite changes in the resolved wave drag contribution to the BDC response to climate change, thereby reducing the impact of changes in OGWD on the BDC response to climate change. By contrast, compensation does not occur at northern high latitudes, where resolved wave driving and the associated downwelling increase with increasing OGWD, both for the present-day climate and the response to climate change. These findings raise confidence in the credibility of climate model projections of the strengthened BDC.
