Atténuer les changements climatiques grâce aux mesures d’utilisation des terres dans les secteurs de l’agriculture et de la foresterie

The document argues that while agriculture and forestry offer cost-effective and rapid opportunities for greenhouse gas (GHG) mitigation, they have been fragmented and largely excluded from international policy frameworks. It highlights the significant potential for carbon sequestration in developing countries' soils and forests, while detailing technical barriers such as non-permanence, leakage, and accounting uncertainties. The briefing specifically discusses Canada's efforts to propose a 'Forward Looking Baseline' for forest management and its domestic regulatory approach to carbon offsets.

• Agriculture and land-use changes, specifically deforestation, are significant contributors to global GHG emissions, with agriculture accounting for approximately 13% and land-use change for 17% of total human-induced emissions.
• Developing countries bear a disproportionate share of emissions from land-use change and forestry, with their contribution exceeding 100% of the global total for that sector in 1990 and 2005, as developed nations had already achieved reductions.
• There is substantial mitigation potential in developing countries' agricultural soils, with estimates suggesting that additional global capacity for carbon sequestration in agricultural lands is around 10% of atmospheric carbon.
• The Clean Development Mechanism (CDM) has seen very slow implementation for afforestation and reforestation (A/R) projects; as of February 1, 2009, only one small-scale A/R project was registered.
• A major barrier to the adoption of forestry projects in carbon markets is the temporary nature of credits (tCERs and lCERs), which expire after a set period and must be replaced, making them less attractive to investors.
• The REDD mechanism faces several unresolved technical and political challenges, including the precise definition of 'forest', the determination of reference levels (historical vs. future trends), and the rights of indigenous peoples.
• Technical obstacles to including agriculture and forestry in future climate agreements include 'leakage' (the displacement of emissions to other areas), non-permanence of carbon sinks due to natural disturbances, and high transaction costs for smallholders.
• Canada proposes a 'Forward Looking Baseline' (FLB) approach for forest management, which compares projected emissions and absorptions against a future reference scenario to better reflect forest dynamics and avoid penalizing countries for natural disturbances.
• Under the 'Turning the Corner' regulatory framework, Canada does not accept forest carbon sink CDM credits for compliance due to their temporary nature and the complexity they add to the national system.
