Brazilian annual precipitation analysis simulated by the Brazilian Atmospheric Global Model.
The strategy for assessing simulations produced by climate models established as part of the Atmospheric Model Intercomparison Project (AMIP) delivers an outline for model analysis, verification/validation, and intercomparison. Numerical models are continuously being developed to find the best repre...

Sustainability assessment of Cerrado and Caatinga biomes in Brazil: a proposal for collaborative index construction in the context of the 2030 Agenda and the Water-Energy-Food Nexus.
The 2030 Agenda framework represents an opportunity for the co-development of local indicators and shares the same principles of cross-sectoral integration and universality as the waterenergyfood nexus. This research aimed to develop a quantitative-collaborative methodology for constructing indicato...

Are exotic earthworms threatening soil biodiversity in the Brazilian Atlantic Forest?
Invasive earthworms are threatening soil biodiversity and ecosystem functioning in formerly earthworm-free boreal and temperate forests. Although exotic earthworms are also found in tropical forests, they have received less attention from soil scientists. Here, we summarize data on earthworm populat...

Incorporating social innovations in the elaboration of disaster risk mitigation policies.
Climate crisis requires intergenerational groups' participation to reduce their vulnerability and to promote disaster risk mitigation public policies. This paper analyzes what and how social innovations can nurture risk mitigation public policies to enhance flood resilience in small cities. A mixed-...

Climate and land use change: future impacts on hydropower and revenue for the Amazon.
Land use and climate change are expected to significantly alter hydrology and consequently electricity production in countries extremely dependent on their water resources, such as Brazil. Therefore, we used the large-scale hydrological model Soil and Water Assessment Tool (SWAT), which we integrate...

Forecast of convective events via hybrid model: WRF and machine learning algorithms.
This presents a novel hybrid 24-h forecasting model of convective weather events based on numerical simulation and machine learning algorithms. To characterize the convective events, 13-year from 2008 up to 2020 of precipitation data from the main airport stations in Rio de Janeiro, Brazil, and atmo...

Performance of an automated conservation status assessment for the megadiverse vascular flora of Brazil.
Conservation status assessments are one of the key scientific measures to inform solutions aiming at minimizing the biodiversity crisis of the Anthropocene, being the IUCN's Red List approach the most widely used and accepted tool for species-level assessment. However, Red Lists are time-consuming b...

Potential use of space-based lightning detection in electric power systems.
Information about lightning activity and its parameters is necessary to design and evaluate the lightning protection of an electrical power system. This information can be obtained from ground-based lightning detection networks that provide information on cloud-to-ground lightning strikes with a loc...
