Abstract Land-based mitigation technologies and practices (LMTs) are critical for achieving the Paris Agreement’s aim of avoiding dangerous climate change by limiting rise in average global surface temperatures. We developed a detailed two-level classification analysis barriers to adoption scaling up LMTs. The review suggests that afforestation/reforestation forest management LMTs with wide application high potential across all continents.

Although most can be cost-effective multiple world regions, limited knowledge concerning their implementation insufficient financing appear main large-scale deployment.

Therefore, social institutional implications need better understood improve public acceptance reduce negative impacts. An integrated system approach is necessary strike balance between ambitious land-based targets socioeconomic environmental goals.

Abstract Tropical forests play a critical role in the hydrological cycle and can influence local regional precipitation 1 . Previous work has assessed impacts of tropical deforestation on precipitation, but these efforts have been largely limited to case studies 2 A wider analysis interactions between precipitation—and especially how any such might vary across spatial scales—is lacking. Here we show reduced over deforested regions tropics. Our results arise from pan-tropical assessment 2003–2017 forest loss using satellite, station-based reanalysis datasets. The effect increased at larger scales, with satellite datasets showing that caused robust reductions scales greater than 50 km. greatest declines occurred 200 km, largest scale explored, for which percentage point by 0.25 ± 0.1 mm per month. Reanalysis products disagree direction responses loss, attribute sparse situ measurements. We estimate future Congo will reduce 8–10% 2100. findings provide compelling argument conservation support climate resilience.

Abstract Vegetation restoration over degraded drylands has considerable climate, carbon and ecosystem benefits, yet its water impacts remain contentious. Previous studies suggest that extra vegetation in could lead to decreased soil moisture runoff caused by enhanced evapotranspiration. However, these ignore important vegetation‐climate feedbacks can partially offset such negative consequences. Here, we examine how revegetation affects budgets China's Loess Plateau, where the world's largest occurs. Despite increased evapotranspiration, long‐term observations exhibit robust increasing trends (2.76 mm yr −2 ) of surface yield a large swath (82.3%) Plateau since starts. This is mainly regional precipitation outweighs increases Numerical experiments further reveal largely driven revegetation‐induced enhancement land‐atmosphere interactions greatly accelerate local recycling. Our findings highlight importance considering assessing hydrological responses large‐scale changes.

Abstract. Changes in evaporation over land affect terrestrial precipitation via atmospheric moisture recycling and, consequently, freshwater availability. Although global at regional and continental scales is relatively well understood, the patterns of local main variables that impact it remain unknown. We calculate ratio (LMR) as fraction evaporated precipitates within a distance 0.5∘ (typically 50 km) its source, identify correlate with globally, study model dependency. derive seasonal annual LMR using 10-year climatology (2008–2017) monthly averaged connections scale obtained from Lagrangian tracking model. find that, annually, an average 1.7 % (SD 1.1 %) returns locally, although large temporal spatial variability, peaks summer wet mountainous regions. Our results show wetness, orography, latitude, convective available potential energy, wind speed, total cloud cover clearly LMR, indicating regions little strong ascending air are particularly favourable for high LMR. Finally, we consistent between different models, yet magnitude varies. can be used to impacts changes on precipitation, implications for, example, regreening water management.

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.

Terrestrial moisture recycling (TMR), characterized by a continuous process comprising green water flow (i.e., terrestrial evaporation), atmospheric transport, and precipitation, functions as nexus connecting hydrosphere, atmosphere, biosphere, anthroposphere. During this process, land cover changes that impact can modify regional remote precipitation patterns, potentially yielding far-reaching effects on resources human livelihoods. However, the comprehensive patterns of transfer across eco-geographical regions in China, their connection with various types vegetation transitions, remain insufficiently evaluated. This study employed an tracking model to quantify China's TMR pattern evaluate hydrological impacts ecosystems through TMR. The results demonstrate significant ratio (52.4 %) considerable recycled volume (1.9 trillion m3/a) over pronounced from south north southwest northeast. Among types, grasslands, croplands, forests play pivotal supportive roles TMR, contributing 738.8, 470.0, 450.0 billion m3/a respectively. Moreover, potential transition between forest cropland exerts most extensive cycle. conversion leads total decrease 44.7 whereas reforestation corresponds increase 74.9 m3/a. provides quantitative approach comprehending its relationship ecosystems, substantiating significance management framework considers contribution change.

Abstract. Recovery time, referring to the duration that an ecosystem needs return its pre-drought condition, is a fundamental indicator of ecological resilience. Recently, flash droughts – characterised by rapid onset and development have gained increasing attention. Nevertheless, spatiotemporal patterns in gross primary productivity (GPP) recovery time factors influencing it remain largely unknown. In this study, we investigate terrestrial China based on GPP using random forest regression model SHapley Additive exPlanations (SHAP) method. A was developed analyse establish response functions through partial correlation for typical drought periods. The dominant driving were determined SHAP results reveal average across approximately 37.5 d, with central southern regions experiencing longest durations. Post-flash-drought radiation emerges as environmental factor, followed aridity index post-flash-drought temperature, particularly semi-arid sub-humid areas. Temperature exhibits non-monotonic relationship where both excessively cold hot conditions lead longer Herbaceous vegetation recovers more rapidly than woody forests, deciduous broadleaf forests demonstrating shortest time. This study provides valuable insights comprehensive water resource management contributes large-scale monitoring efforts.
