Abordando os efeitos biofísicos das florestas nas políticas nacionais sobre o clima: oportunidades no Chile

The report examines the non-carbon biophysical effects of forests—albedo, evapotranspiration, surface roughness, and aerosols—and their impact on local and global temperatures and precipitation. Using Chile as a case study, it highlights how deforestation of native vegetation, such as the matorral, has contributed to local surface temperature increases. The document proposes specific policy enhancements for Chile, including adjusting its Nationally Determined Contribution (NDC) to favor native species over exotic plantations, expanding the ARClim risk assessment platform, and incorporating biophysical indicators into the National Strategy for Climate Change and Plant Resources (ENCCRV). It suggests that Chile's approach can serve as a model for other UNFCCC parties to recognize deforestation as a climate hazard beyond carbon emissions.

• Forests influence climate through four primary non-carbon biophysical processes: albedo (solar energy reflection), evapotranspiration (moisture release for cooling), surface roughness (wind turbulence that lifts heat), and aerosols (particles affecting cloud color and atmospheric chemistry).
• Deforestation of tropical forests contributes 50% more to global warming than carbon accounting alone suggests, while locally, the loss of forest cooling can lead to temperature spikes of over 7.6C in the hottest part of the day for local communities.
• Chile's 2020 NDC goal to plant 200,000 hectares of new forests by 2030 allows for 130,000 hectares of exotic species; however, these provide limited climate benefits compared to native species due to lower albedo.
• The ARClim climate risk assessment platform, which uses a 5-kilometer spatial resolution, could be expanded to include deforestation and its effect on temperature to prioritize adaptation measures.
• The National Strategy for Climate Change and Plant Resources (ENCCRV) currently relies solely on carbon emissions and sequestration as mitigation indicators, ignoring biophysical cooling benefits.
• Regional and communal development plans in Chile, such as those in the Los Rios region or the commune of Futrono, provide opportunities to implement targeted forest conservation to secure financial resources and political support.
