Even cooler insights: On the power of forests to (water the Earth and) cool the planet

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(2)

Published: Feb. 1, 2024

Scientific innovation is overturning conventional paradigms of forest, water, and energy cycle interactions. This has implications for our understanding the principal causal pathways by which tree, vegetation cover (TFVC) influence local global warming/cooling. Many identify surface albedo carbon sequestration as TFVC affects Moving toward outer latitudes, in particular, where snow more important, effects are perceived to overpower sequestration. By raising albedo, deforestation thus predicted lead cooling, while increasing forest assumed result warming. Observational data, however, generally support opposite conclusion, suggesting poorly understood. Most accept that temperatures influenced interplay incoming shortwave (SW) radiation, partitioning remaining, post-albedo, SW radiation into latent sensible heat. However, extent avoidance heat formation first foremost mediated presence (absence) water not well both mediates availability on land drives potential production (evapotranspiration, ET).

Published: Jan. 1, 2024

Abstract Forestation efforts are accelerating across the globe in fight against global climate change, order to restore biodiversity, and improve local livelihoods. Yet, so far non‐local effects of forestation on rainfall have largely remained a blind spot. Here we build upon emerging work propose that targeted enhancement may also be considered prioritization forestation. We show tools achieve this rapidly becoming available, but identify drawbacks discuss which further developments still needed realize robust assessments face change. programs then mitigate not only change itself its adverse form drying.

On the unique value of forests for water: Hydrologic impacts of forest disturbances, conversion, and restoration

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(2)

Published: Jan. 29, 2024

Abstract We need empirical evidence on the impacts of land‐use change hydrological processes to guide policies and land management decisions. Based a global meta‐analysis 287 primary studies covering 1049 data points in 58 countries across 12 biomes, we review hydrologic process changes resulting from native forest disturbances conversions other types. Infiltration rates consistently fell over 50%, overland flow increased evapotranspiration as share rainfall declined when forests were disturbed or converted. Changes total evapotranspiration, interception, streamflow less consistent direction, while restored returned infiltration function pre‐conversion levels. Forests, perhaps especially forests, have unique value supporting regulating processes, they can reduce erosion, improve water infiltration, potentially enhance supply, including downwind locations. thus underscore calls for increasing proportion reforested areas with species landscape restoration planned this decade.

Land, Journal Year: 2025, Volume and Issue: 14(2), P. 216 - 216

Published: Jan. 21, 2025

Preserving soil is crucial for addressing the key challenges of new millennium, like climate change and biodiversity loss. Spatial planning plays a pivotal role in stopping consumption degradation, thereby safeguarding soils that provide valuable ecosystem services. With advent System Environmental-Economic Accounting by UN, countries are developing shared protocol biophysical monetary quantification However, downscaling efforts necessary must be conditioned national context, policies, economic dynamics, data availability. Therefore, this research proposes quality assessment methodology based on its value at sub-regional level northern Italy, building upon guidelines. This study includes modeling mapping outputs involving six services through eight indicators these Both assessments have been conducted over two time periods to highlight impacts land cover transformation.

Abstract Climate change requires major mitigation efforts, mainly emission reduction. Carbon sequestration and avoided deforestation are complementary strategies that can promote nature conservation local development but may also have undesirable impacts. We reviewed 246 articles citing impacts, risks, or concerns from carbon projects, 78 others related to this topic. Most of the impacts cited focus on biodiversity, especially in afforestation social effects projects. Concerns were raised about project effectiveness, permanence stored, leakage. Recommendations include accounting for uncertainty, assessing both contribution climate change, defining permanence, creating contingency plans, promoting proposing alternative livelihoods, ensuring a fair distribution benefits, combining timber production sequestration, sustainable minimizing A holistic approach combines conservation, poverty alleviation must be applied. The potential occurrence negative does not invalidate projects makes it advisable conduct proper environmental impact assessments, considering direct indirect while maximizing positive ones, weighing trade‐offs between them guide decision‐making.
