Анотация: The review highlights the vast untapped potential for climate change mitigation and adaptation associated with improved carbon sequestration in pastoral systems and rangelands. Much of this potential lies in soil carbon sequestration. Its neglect during the Kyoto process1 stemmed from concerns regarding perceived difficulties of measurement and monitoring due to soil spatial variability, and of ensuring permanence (IPCC, 2008). Recent negotiations have highlighted the potential for Reducing Emissions from Deforestation and Forest Degradation (REDD) and for carbon sequestration in soils and above-ground biomass in other lands besides forests. Evidence regarding the potential for carbon sequestration in rangelands and grasslands is continually accumulating. The review demonstrates that there is a strong justification for a concerted international process to explore and support efforts for achieving carbon sequestration and promoting sustainable (agro)-pastoral livelihoods in dryland systems through the ongoing post-Kyoto deliberations and negotiations.
