Potential Climate Change

This study estimates the impact of potential climate change, and human interference (anthropogenic deforestation), on temperate forest carbon pool change in the capital area of South Korea, using a dynamic global vegetation model (DGVM). Additionally, the characteristics of forest carbon pool change were simulated based on a biogeochemical module. The change of atmospheric carbon dioxide (CO2) concentration is deeply related to the change of the forest carbon pool, which is estimated with the measures of Net Primary Productivity (NPP), and Soil Carbon Storage (SCS). NPP and SCS were estimated at 2.02–7.43 tC ha−1 year−1 and 34.55–84.81 tC ha−1, respectively, during the period 1971–2000. SCS showed a significant decreasing tendency under the conditions of increasing air temperature, and precipitation, in the near future (2021–2050), and far future (2071–2100), which were simulated with future-climate scenario data without any human interference. Besides, it is estimated that the temporal change in NPP indicates only a small decrease, which is little influenced by potential climate change. In the case of potential climate change plus human interference, the decrease rate of NPP and SCS were simulated at 17–33% and 21–46%, respectively, during 2000–2100. Furthermore, the effect of potential human interference contributes to 83–93% and 61–54% of the decrease rate of NPP and SCS, respectively. The decline in the forest carbon pool simulated in this study can play a positive role in increasing atmospheric carbon dioxide. Consequently, the effect of potential human interference can further accelerate the decline of the temperate forest carbon pool. For the effective reduction of carbon dioxide emissions in urbanizing areas, it would be more effective to control human interference. Consequently, this study suggests that a rate of reforestation corresponding to the deforestation rate should be at least maintained, with long term monitoring and modeling-related studies, against climate change problems.

Wood Harvest

Abstract Background A commonly held idea is that substituting wood for fossil fuels and energy intensive materials is a better strategy in mitigating climate change than storing more carbon in forests. This opinion, although ratified by the forest and energy policies of many countries, especially in Europe, remains highly questionable for at least two reasons. Results Firstly, the carbon footprints of wood-products are underestimated as far as the “carbon neutrality” assumption is involved in their life cycle analysis, as it is most often the case. As a matter of fact, when taking into account the forest carbon dynamics consecutive to wood harvest and the limited lifetime of products, these carbon footprints are time-dependant and their presumed values under the carbon neutrality assumption are achieved only in steady-state conditions. For time horizons comparable with the climatic deadlines, the values to apply may be of the same order as the carbon mass in the harvested wood from which the products originate. Secondly, even if carbon footprints are correctly estimated, the benefit of substitutions is overestimated when all or part of the wood products are supposed to replace non-wood products whatever the market conditions. Indeed, substitutions can be considered as effective only if an increase in wood harvesting implies verifiably a global reduction in production of non-wood products. Conclusions Most studies that advocate energy or material substitutions lack rigour to these respects and incite the increase in wood harvesting. Such an increase impedes forest carbon storage and could be counter-productive for climate change mitigation objectives.
