Increasing Fire Activity in African Tropical Forests Is Associated With Deforestation and Climate Change

Geophysical Research Letters, Journal Year: 2024, Volume and Issue: 51(9)

Published: May 2, 2024

Abstract Fires were historically rare in tropical forests of West and Central Africa, where dense vegetation, rapid decomposition, high moisture limit available fuels. However, increasing heat drought combined with forest degradation fragmentation are making these areas more susceptible to wildfires. We evaluated historical patterns Moderate Resolution Imaging Spectroradiometer active fires African from 2003 2021. Trends mostly positive, particularly the northeastern southern Congo Basin, concentrated deforestation. Year‐to‐year variation was synchronized temperature vapor pressure deficit. There anomalously fire activity across region during 2015–2016 El Niño. These results contrast drier woodlands savannas, has been decreasing. Further attention is needed understand their global impacts on carbon dynamics local implications for biodiversity human livelihoods.

Published: Feb. 4, 2024

This study presents an Importance-Performance Analysis (IPA) to evaluate the management strategies for Human-Orangutan Conflict (HOC) in Aceh, Indonesia. Utilizing IPA Grid, research categorizes various into four quadrants, each reflecting different levels of community-perceived importance and performance. Strategies like "Orangutan-Safe Fences" "Community-Based Natural Resource Management (CBNRM) Orangutans" Quadrant A are both important performing well, underscoring effectiveness current efforts these areas. Significantly, "Traditional Measures Orangutan Deterrence," which include non-harmful, traditional methods such as use specific noise deterrents, physical barriers, community-led patrols discourage orangutans from entering human areas, alongside "Quick Response Program Incidents," placed B.. In C, "Strengthen Law Enforcement Conservation Policies" deemed less crucial underperforming, suggesting a lower priority immediate resource allocation. Lastly, D includes well-performing but critical "Early Warning Systems Presence" "Raise Local Awareness About Orangutans," pointing potential over-investment. The study's findings advocate strategic reallocation resources highlight aligning conservation with community priorities effective sustainable HOC management.

State of the art and for remote sensing monitoring of carbon dynamics in African tropical forests

Frontiers in Remote Sensing, Journal Year: 2025, Volume and Issue: 6

Published: March 17, 2025

African tropical forests play a crucial role in global carbon dynamics, biodiversity conservation, and climate regulation, yet monitoring their structure, diversity, stocks changes remains challenging. Remote sensing techniques, including multi-spectral data, lidar-based canopy height vertical structure detection, radar interferometry, have significantly improved our ability to map forest composition, estimate biomass, detect degradation deforestation features at finer scale. Machine learning approaches further enhance these capabilities by integrating multiple data sources produce maps of attributes track over time. Despite advancements, uncertainties remain due limited ground-truth validation, the structural complexity large spatial heterogeneity forests. Future developments remote should examine how multi-sensor integration high-resolution from instruments such as Planet, Tandem-X, SPOT AI methods can refine storage function maps, large-scale tree biomass improve detection down level. These advancements will be essential for supporting science-based decision-making conservation mitigation.
