ASSESSMENT AND MEASUREMENT ISSUES RELATED TO SOIL CARBON SEQUESTRATION IN LAND-USE, LAND-USE CHANGE, AND FORESTRY (LULUCF) PROJECTS UNDER THE KYOTO PROTOCOL

摘要: Mitigating the potential large negative impacts of a change in earth's climate will require strong and definite actions different economic sectors, particularly within agriculture forestry. Specifically, soils deserve close examination due to their carbon mitigation potential. The Kyoto protocol establishes possibility for crediting greenhouse gas emission reductions from forestry activities. In most circumstances, those regarding developing countries, activities be carried out through projects. These projects have meet series criteria, benefits measurable, transparent, verifiable certified. criteria include: establishing credible baselines (without-project or reference scenario), additionality, permanence, quantifying reducing leakage gases across project borders, coping with natural human induced risks, accurately measuring changes stocks using accounting techniques, – case Clean DevelopmentMechanism resulting sustainable development benefits. this paper we describe methods approaches that been developed cope discuss implications sequestration soils. Soil represents largest pool terrestrial ecosystems, has estimated one potentials sequester worldwide. However, getting credits soil presents several challenges: need monitor small incremental content relative pools, long-time periods accrue full benefits, high local variability content, relatively costly measurement procedures. Also, responses C are complex careful attention. time dynamics land use changes, diversity types, soil-plant interactions, availability accurate inventories, should considered successfully implement LULUCF
