Parameter uncertainty dominates C-cycle forecast errors over most of Brazil for the 21st century
Identification of terrestrial carbon (C) sources and sinks is critical for understanding the Earth system as well as mitigating and adapting to climate change resulting from greenhouse gas emissions. Predicting whether a given location will act as a C source or sink using terrestrial ecosystem model...

Evaluation of hydrogel use in the development of Rapanea ferruginea with water restriction by vibrational Fourier Transform Infrared Spectroscopy (FTIR-UATR)
This study evaluated the use of hydrogel on the development of Rapanea ferruginea under water restriction through Vibrational Fourier Transform Infrared Spectroscopy (FTIR-UATR). Seedlings of approximately 30 cm height were transferred in pots with 3 L of soil. The group of seedlings was separated ...

Regional distance routes estimation for municipal solid waste disposal, case study São Paulo state, Brazil.
The urban population increase in the world, the economic expansion, and the rise in living standards associated with societys habits and lifestyles accelerated the municipal solid waste (MSW) generation in undeveloped countries, such as in Brazil, in which the generation increased by 25% from 2012...

Previsão de curto prazo da radiação solar no Brasil usando movimento das nuvens com base em dados de satélite
Um dos principais desafios apontados para o futuro passa pela redução da dependência de combustíveis fósseis, apostando em um aumento da integração e aproveitamento energético de recursos renováveis. A integração em grande escala de fontes de energia renovável intermitentes nos sistemas ...

Large methane emissions from the Pantanal during rising water-levels revealed by regularly measured lower troposphere CH4 profiles
The Pantanal region of Brazil is the largest seasonally flooded tropical grassland and, according to local chamber measurements, a substantial CH4 source. CH4 emissions from wetlands have recently become of heightened interest because global atmospheric 13CH4 data indicate they may contribute to the...

The anthropocene landscape and ecosystem services in the closure of sand mining:
Geodiversity is a determinant of mining patterns, because its nature defines the interaction with humans, type of exploitation, and, consequently, ecosystem services (ES) of the final landscape. The environmental recovery obligations defined in the legislation serve as a good guidance, but sand mini...

Advancing urban water security: the urbanization of water–society relations and entry–points for political engagement.
We seek to advance a critical and relational concept of urban water security that theorizes urban processes in relation to the hydro-social dynamics that produce experiences of water securities and insecurities at multiple scales. Our intention is to set out an analytical framework that both examin...

The effects of Amazon deforestation on non-timber forest products
The relationships between deforestation and non-timber forest products (NTFPs) supply chains are investigated in 532 municipalities throughout the Brazilian Amazon. The NTFP production of acai berry (Euterpe spp.), andiroba (Carapa spp.), Brazil nut (Bertholletia excelsa Bonpl.), and tonka bean (Dip...

Robust late twenty-first century shift in the regional monsoons in RegCM-CORDEX simulations
We use an unprecedented ensemble of regional climate model (RCM) projections over seven regional CORDEX domains to provide, for the first time, an RCM-based global view of monsoon changes at various levels of increased greenhouse gas (GHG) forcing. All regional simulations are conducted using RegCM4...

Water security in two megacities: observations on public actions during 2020 in Sao Paulo and London.
This paper discusses water security and wellbeing within a public health perspective and focuses on urban areas with high population density. It analyses access to safe water and the multiple challenges to water security in two megacities: São Paulo and London, comparing differences and similaritie...

Large-scale variations in the dynamics of Amazon forest canopy gaps from airborne lidar data and opportunities for tree mortality estimates.
We report large-scale estimates of Amazonian gap dynamics using a novel approach with large datasets of airborne light detection and ranging (lidar), including five multi-temporal and 610 single-date lidar datasets. Specifically, we (1) compared the fixed height and relative height methods for gap d...

Constraining Amazonian land surface temperature sensitivity to precipitation and the probability of forest dieback.
The complete or partial collapse of the forests of Amazonia is consistently named as one of the top ten possible tipping points of Planet Earth in a changing climate. However, apart from a few observational studies that showed increased mortality after the severe droughts of 2005 and 2010, the evide...
