Several large-scale drivers of both anthropogenic and natural environmental changes are interacting nonlinearly in the transition zone between eastern Amazonia adjacent Cerrado, considered to be another Brazilian agricultural frontier. Land-use change for agrobusiness expansion together with climate Cerrado may have induced a worsening severe drought conditions over last decade. Here we show that largest warming drying trends tropical South America during four decades observed precisely Amazonia-Cerrado region, where they induce delayed wet-season worsen Our results evidence an increase temperature, vapor pressure deficit, subsidence, dry-day frequency, decrease precipitation, humidity, evaporation, plus delay onset wet season, inducing higher risk fire dry-to-wet season. These findings provide observational increasing climatic this area, which is sensitive global food security, need reconcile protection biomes.

The soil carbon (C) saturation concept suggests an upper limit to the storage of organic (SOC). It is set by mechanisms that protect matter from mineralization. Biochar has capacity new C, including rhizodeposits and microbial necromass. However, decadal-scale which biochar influences molecular diversity, spatial heterogeneity, temporal changes in SOC persistence, remain unresolved. Here we show C ceiling a Ferralsol under subtropical pasture was raised second application Eucalyptus saligna 8.2 years after first application-the 9.3 Mg ha-1 this another 2.3 ha-1. Linking direct visual evidence one-, two-, three-dimensional analyses with quantification, found high heterogeneity functional groups resulted retention necromass microaggregates (53-250 µm) mineral fraction (<53 µm). Microbial C-use efficiency concomitantly increased lowering specific enzyme activities, contributing decreased mineralization native 18%. We suggest can be lifted using (sub)tropical grasslands globally.

Abstract Spatially explicit information on forest management at a global scale is critical for understanding the status of forests, planning sustainable and restoration, conservation activities. Here, we produce first reference data set prototype globally consistent map with high spatial detail most prevalent classes such as intact managed forests natural regeneration, planted plantation (rotation up to 15 years), oil palm plantations, agroforestry. We developed dataset 226 K unique locations through series expert crowdsourcing campaigns using Geo-Wiki ( https://www.geo-wiki.org/ ). then combined samples time from PROBA-V satellite imagery create wall-to-wall 100 m resolution year 2015, class accuracies ranging 58% 80%. The present ecosystems can be used investigating value species, their services.
