“…In GHG mitigation projects, for example, it is not uncommon to find differing "definitions" and interpretations of source and sink categories and uncertainties about the basic processes leading to emissions and/or removals. To estimate the effects of harvest on C stocks, accurate information is required on three items: preharvest biomass, the fraction of this biomass harvested or damaged, and the fraction of the harvested biomass removed; much of these, however, are not available (de Jong, 2001).…”

During the past three decades, agroforestry has become recognized the world over as an integrated approach to sustainable land use because of its production and environmental benefits. Its recent recognition as a greenhouse gas-mitigation strategy under the Kyoto Protocol has earned it added attention as a strategy for biological carbon (C) sequestration. The perceived potential is based on the premise that the greater efficiency of integrated systems in resource (nutrients, light, and water) capture and utilization than single-species systems will result in greater net C sequestration. Available estimates of C-sequestration potential of agroforestry systems are derived by combining information on the aboveground, time-averaged C stocks and the soil C values; but they are generally not rigorous. Methodological difficulties in estimating C stock of biomass and the extent of soil C storage under varying conditions are compounded by the lack of reliable estimates of area under agroforestry. We estimate that the area currently under agroforestry worldwide is 1,023 million ha. Additionally, substantial extent of areas of unproductive crop, grass, and forest lands as well as degraded lands could be brought under agroforestry. The extent of C sequestered in any agroforestry system will depend on a number of site-specific biological, climatic, soil, and management factors. Furthermore, the profitability of C-sequestration projects will depend on the price of C in the international market, additional income from the sale of products such as timber, and the cost related to C monitoring. Our knowledge on these issues is unfortunately rudimentary. Until such difficulties are surmounted, the low-cost environmental benefit of agroforestry will continue to be underappreciated and underexploited.

“…Several simulation studies have been carried out in Mexico based on the CO2FIX model (including those of Cairns et al 1995;De Jong et al 1995De Jong 2001;Masera et al 2003;De Jong et al 2007). The model has also been successfully applied to study the C baseline for pine-oak forests in the JMR, estimating a maximum amount of C of 236.6 Mg/ha as the result of adding the C present in living tree C biomass (208.7 Mg/ha) and the soil organic C from dead trees (27.9 Mg/ha; Alvarez and Rubio 2013).…”

Forest managers and policy-makers are being encouraged to incorporate carbon sequestration as a criterion for decision-making. This is a great challenge for small-scale forestry where the conspicuous lack of practical knowledge available for managers prevents the implementation of criteria to promote carbon sequestration. The carbon simulation model CO2FIX combined with local data could provide valuable information for C sequestration in these small-scale forestry systems. The research reported here focuses on community forestry located in the Juarez Mountain Range (Oaxaca State, Mexico), and analyzes the influences of forest management and wood-use (20 scenarios based on five forest management plans and four wood-use strategies) on the changes of C stock (biomass C, soil organic C, products C and fuelwood C) over time. The comparison of the whole stocks to reference results show that group-selection, based on an uneven-aged forest management system involving small patches, has only about half the C benefit relative to clear-cutting harvesting. A forest management strategy focused on oak logwood has a lower C benefit (70 %), and a forest management strategy focused on oak fuelwood has a higher C benefit (120 %) relative to the average of the studied wooduse strategies. Thus, in the study area forest managers and policy-makers who wish to mitigate climate change should increase the rotation period from 40 to 50 years in clear-cutting areas, continue with 40 years in group-selection areas, and promote the use of oak for bioenergy.
