Abstract Tropical forest degradation from selective logging, fire and edge effects is a major driver of carbon biodiversity loss 1–3 , with annual rates comparable to those deforestation 4 . However, its actual extent long-term impacts remain uncertain at global tropical scale 5 Here we quantify the magnitude persistence multiple types on structure by combining satellite remote sensing data pantropical moist cover changes estimates canopy height biomass spaceborne 6 light detection ranging (LiDAR). We estimate that decreases owing logging 15% 50%, respectively, low recovery even after 20 years. Agriculture road expansion trigger 20% 30% reduction in edge, persistent being measurable up 1.5 km inside forest. Edge encroach 18% (approximately 206 Mha) remaining forests, an area more than 200% larger previously estimated 7 Finally, degraded forests 50% are significantly vulnerable subsequent deforestation. Collectively, our findings call for greater efforts prevent protect already meet conservation pledges made recent United Nations Climate Change Biodiversity conferences.

Abstract Under current emission trajectories, temporarily overshooting the Paris global warming limit of 1.5 °C is a distinct possibility. Permanently exceeding this would substantially increase probability triggering climate tipping elements. Here, we investigate risks associated with several policy-relevant future scenarios, using stylised Earth system model four interconnected We show that following policies century commit to 45% risk by 2300 (median, 10–90% range: 23–71%), even if temperatures are brought back below °C. find increases every additional 0.1 overshoot above and strongly accelerates for peak 2.0 Achieving maintaining at least net zero greenhouse gas emissions 2100 paramount minimise in long term. Our results underscore stringent reductions decade critical planetary stability.

Human pressures have pushed the Earth system deep into Anthropocene, threatening its stability, resilience and functioning. The Planetary Boundaries (PB) framework emerged against these threats, setting safe levels to biophysical systems processes that, with high likelihood, ensure life-supporting Holocene-like conditions. In this Review, we synthesize PB advancements, detailing emergence mainstreaming across scientific disciplines society. nine PBs capture key functions regulating system. operating space has been transgressed for six of these. science is essential prevent further risks sparked new research on precision boundaries. development within planetary boundaries defines sustainable development, informing advances in social sciences. Each translates a finite budget that world must operate within, requiring strengthened global governance. adopted by businesses informed policy world, thinking about fundamental justice concerns, inspired, among other concepts, commons, health doughnut economics. Future work increase frequency analyses, and, together observation data analytics, produce high-resolution real-time state health. Boundary — which provides guardrails maintain humanity received widespread societal interest. This Review outlines thinking, including relevance science, justice, governance, economics sustainability.

Abstract The Amazon basin is experiencing severe droughts that are expected to worsen with climate change. Riverine communities especially vulnerable these extreme events. This study investigates the experiences of Brazilian Amazonian during occurring from 2000-2020. We assess distribution settlements at risk prolonged isolation low-water periods, along impacts reported in digital news outlets. Using historic time series river levels 90 gauges, we look how long lasted regions impacts. Results indicate 2005, 2010, and 2016 were most severe, over an additional month low water those years. Such drought events routinely disrupt inland transport isolate local populations, limiting access essential goods (food, fuel, medicine) basic services (healthcare, education). Given this new reality, countries must develop long-term strategies for mitigation, adaptation, disaster response.

ABSTRACT The Brazilian western Amazon region is currently experiencing its largest laboratory confirmed Oropouche virus (OROV) outbreak, with nearly 6,000 reported cases in the states of Amazonas (AM), Acre (AC), Rondônia (RO), and Roraima (RR), between August 2022 March 2024. Here, we sequenced analyzed 382 full-length OROV genomes from human samples collected 2024 all four states, aiming to trace origin genetic evolution leading current outbreak. Genomic analyses revealed that recent upsurge coincides emergence a novel reassortant viral lineage containing M segment viruses detected eastern 2009 2018 L S segments Peru, Colombia, Ecuador 2008 2021. likely emerged Central AM state 2010 2014 displayed long-range silent dispersion during second half 2010s. 2022-2024 epidemic was spatially segregated into three major subpopulations located RR, AMACRO (a bordering AC, RO, AM-Southern region), AM-Central (which includes Amazonas’ capital, Manaus) regions. peak transmissions regions occurred rainy season basin. Furthermore, our phylodynamics reconstructions showed spread driven mainly by short-range (< 2 km) movements, an average dispersal rate ≤ 1.2 km/day, consistent pattern active flight infected vectors. Nevertheless, substantial proportion (22%) (> 10 migrations were also detected, via activities. Our data provides unprecedented view real-time neglected emergent pathogen. Moreover, results emphasize need for widespread, long-term genomic surveillance better understand real burden within beyond region.

The expansion of agricultural frontiers in the Amazon region poses a significant threat to forest conservation and biodiversity persistence. This study focuses on Pará state, Brazil, aiming identify characterize predominant production systems by combining remote sensing data landscape structure metrics. A rule-based classification tree algorithm is applied classify hexagonal cells based land cover, deforestation patterns, distance from dairy facilities. results reveal three dominant systems: Natural Region, Non-Intensive Beef, Initial Front, with livestock being prominent. analysis indicates that there correlation between productive area deforestation, emphasizing role agriculture as driver loss. Moreover, road networks significantly influence system spatial distribution, highlighting importance infrastructure use dynamics. Shannon diversity index reveals areas exhibit greater cover classes, reflecting wider range modifications. In contrast, natural vegetation show lower values, suggesting these are more intact less affected human activities. These findings underscore urgent need for sustainable development policies will mitigate threats resilience state.
