Forests for Carbon Sequestration or Fossil Fuel Substitution? A Sensitivity Analysis

摘要: Among the proposals for mitigating increase of atmospheric CO2 are possibility reforesting degraded lands to sequester C or using sustainable forest harvests displace fossil fuels. Storing on-site in forests and harvesting a flow products not necessarily conflicting options if we recognize that their relative merits net emissions will depend on site-specific factors, such as productivity efficiency with which harvested material is used. Since land available reforestation development plantations limited, different mitigation strategies need be considered. We use mathematical model stocks flows compare effect atmosphere two approaches over range values product use. When sustainably-produced used inefficiently fuels, greater benefit achieved through protection standing forests, increasing rate stand growth yields little gain. However, when efficiently harvest produces benefits, increases rapidly productivity.
