Land-use change and global climate policies; Usage des terres et politiques climatiques globales

Abstract

This PhD thesis assess the role of land-use dynamics and carbon sequestration within climate policies. First, it describes the emergence, from the Rio-1992 to the Marrakech Accords (2001), of diplomatic controversies upon carbon sinks, in the context of the progressive constitution of a scientific basis on terrestrial carbon sinks. It questions the ability of the actual form of international climate regime to generate the appropriate incentives to sequester within the forestry sector in developed countries, or to control tropical deforestation. Second, the contribution of land-use change to atmospheric CO{sub 2} rise is quantified using a newly designed model of the global carbon cycle and regional land-use (OSCAR). We show that carbon emitted via land-use is not equivalent to fossil carbon emission in respect to atmospheric CO{sub 2} rise. This effect, all the more than land-use emissions are increasing, requires a greater mitigation effort to stabilize atmospheric CO{sub 2}. Finally, optimal timing of mixed climate policies involving fossil emissions mitigation and biological sequestration is assessed within an inter temporal cost-benefit framework. We show that the social value of sequestered carbon depends on anticipating future climate damages. Within optimal control models, this links the timing of sequestration to fossil effort and to  More>>

Within optimal control models, this links the timing of sequestration to fossil effort and to the evolution of climate damages; if the latter are uncertain, but might be revealed at a later date, then it might be optimal to reserve part of the limited sequestration potential to cut off an eventual future abatement cost peak, were a climate surprise to finally imply stringent concentration ceilings.
