Intercomparison of Machine Learning Models to Determine the Planetary Boundary Layer Height Over Central Amazonia.

The planetary boundary layer height (zi) is a key parameter in meteorology and climatology, influencing weather prediction, cloud formation, and the vertical transport of scalars and energy near Earth's surface. This study compares multiple machine learning (ML) models that predict zi from surface m...

Towards sustainable aquaculture in the Amazon.

Aquaculture in the Amazon holds the potential to meet increasing food demands while offering economic opportunities in a region facing deforestation and biodiversity loss. However, expanding aquaculture in this biodiverse region comes with complex environmental and social trade-offs. This Review exp...

The multifaceted spectra of power − A participatory network analysis on power structures in diverse dryland regions.

With intensifying climate change impacts on dryland regions, it is essential to better understand how actors relate to each other to sustainably manage natural resources. The literature on environmental governance networks has studied actor collaborations, but it is only starting to investigate netw...

Current constraints to reconcile tropical forest restoration and bioeconomy.

Large-scale forest restoration is vital for delivering a broad array of ecosystem services benefits to society. However, it is often perceived as an economically noncompetitive land use choice. Integrating economic opportunities into restoration aligns socioeconomic and environmental goals, reducing...

Constraining 2010-2020 Amazonian carbon flux estimates with satellite solar-induced fluorescence (SIF).

Amazonia's net biome exchange (NBE), the sum of biogenic and wildfire carbon fluxes, is a fundamental indicator of the state of its ecosystems. It also quantifies the magnitude and patterns of short- and long-term carbon dioxide sources and sinks but is poorly quantified and out of equilibrium (non-...

Integrating Sustainable Development Goals into the nexus approach.

The increased intensity and frequency of future climate extremes might invalidate current water policies, particularly in the case of basins with competing water uses. To analyze these challenges, the nexus approach was proposed as an alternative to integrated resources management by simultaneously ...

Climate benefits of Amazon secondary forests-recent advances and research needs.

A quarter of the deforested Amazon has regrown as secondary tropical forest and yet the climatic importance of these complex regenerating landscapes is only beginning to be recognised. Advances in satellite remote-sensing have transformed our ability to detect and map changes in forest cover, while ...

Assessment of subseasonal streamflow predictions in a tropical basin.

Brazil is a country highly dependent on hydroelectricity. Because electricity generation is programmed monthly, one of the most critical information is the inflow of the main hydropower plants of the country. In this context, this study evaluates the predictability and accuracy of raw and bias-corre...

Energy balance, water use efficiency, and photochemistry of two globally cultivated rainfed cactus species.

Linking knowledge of energy fluxes and evapotranspiration (ET) in cacti is useful for understanding plant growth, which acts as an extremely important feed source for dairy farming. However, there is little quantitative understanding of the latent (LE) and sensible (H) heat fluxes in drylands of cac...
