Do the type of impact and vulnerability dimension matter when assessing natural hazard vulnerability?

Communities across the United States are continually impacted by natural hazards, leading to material and human losses. Natural Hazard Vulnerability (NHV) assessments can help identify variables that can increase the community's susceptibility to these losses. Several studies have assessed NHV, but ...

Increased Amazon carbon emissions mainly from decline in law enforcement.

The Amazon forest carbon sink is declining, mainly as a result of land-use and climate change14. Here we investigate how changes in law enforcement of environmental protection policies may have affected the Amazonian carbon balance between 2010 and 2018 compared with 2019 and 2020, based on atmosphe...

Multi-experiment assessment of soil nitrous oxide emissions in sugarcane.

Soil nitrous oxide (N2O) fluxes comprise a significant part of the greenhouse gas emissions of agricultural products but are spatially and temporally variable, due to complex interactions between climate, soil and management variables. This study aimed to identify the main factors that affect N2O em...

Analysis of past and future urban growth on a regional scale using remote sensing and machine learning.

This research investigates Land Use and Land Cover (LULC) changes in the Porto Alegre Metropolitan Region (RMPA). A 30-year historical analysis using Landsat satellite imagery was made and used to develop LULC scenarios for the next 20 years using a Multilayer Perceptrons (MLP) model through an Arti...
