Large Methane Emissions From the Pantanal During Rising Water‐Levels Revealed by Regularly Measured Lower Troposphere CH4 Profiles

Global Biogeochemical Cycles, Volume 35, Issue 10, October 2021., 2021
Abstract 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 resumption of atmospheric CH4 growth since ...

Applying Sewage Sludge to Eucalyptus grandis Plantations: Effects on Biomass Production and Nutrient Cycling through Litterfall

Applied and Environmental Soil Science, Volume 2011, Issue 1, 2011., 2011
In most Brazilian cities sewage sludge is dumped into sanitary landfills, even though its use in forest plantations as a fertilizer and soil conditioner might be an interesting option. Sewage sludge applications might reduce the amounts of mineral fertilizers needed to sustain the productivity on infertile tropical soils. However, sewage sludge must be

Strategic Assessment of Treated Wastewater Reuse Potential in Brazilian Watersheds Using Analytic Hierarchy Process

Engineering Reports, Volume 8, Issue 5, May 2026.
Assessment of treated wastewater reuse potential in two Brazilian river basins using the Analytic Hierarchy Process (AHP). The map illustrates the Rio dos Sinos Watershed, where industrial reuse predominates (46%), while in the Rio Sapucaí Watershed reuse for irrigation is dominant (68%).

Amazonia 2040: Spatial‐explicit futures scenarios for the mosaic of protected areas in the Lower Rio Negro (MBRN), Brazil

Ecological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
Spatial‐explicit futures scenarios were applied in the Mosaic of Protected Areas of the Lower Rio Negro (MBRN), for co‐creating scenarios for the MBRN in the year 2040. Scenario making enabled negotiating desirable futures, aligning values and goals.

Stochastic Modelling of Daily Precipitation in Semi‐Arid Regions Using Markov Chains and Parametric Distributions

International Journal of Climatology, Volume 46, Issue 4, 30 March 2026.
This study applies stochastic rainfall models combining Markov Chains with gamma and mixed exponential distributions to a semi‐arid climate in Northeast Brazil. Model structures were evaluated using Bayesian Information Criterion (BIC), with maximum likelihood (MLM) for parameter estimation and cumulative distribution functions (CDFs) for validation ...

Critical Slowing Down Reveals Hydrologic Resilience Loss Across Amazon Sub‐Basins

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract The Amazon's hydroclimate exhibits basin‐scale early‐warning signals of critical slowing down (CSD), a statistical signature of declining resilience as systems approach critical transitions. We apply a multi‐metric framework to precipitation, evapotranspiration, Soil moisture (SM), and extreme streamflows, tracking rolling variance, lag‐1 ...
