Key Takeaways
- Nearly 20 trees are cut down every second in the Amazon, contributing to Brazil's greenhouse gas emissions.
- MapBiomas utilizes satellite imagery and machine learning to create real-time land use maps.
- This mapping technology significantly increases enforcement actions and redirects financing towards sustainable practices.
- MapBiomas data supports diverse applications, from protecting indigenous rights to water management.
Deep Dive
- Approximately 20 trees are cut down every second in the Amazon, making deforestation a major source of Brazil's greenhouse gas emissions.
- Tropical forests are critical for climate regulation, absorbing carbon, but deforestation releases stored carbon.
- In 2024, tropical forests lost an area equivalent to Rwanda, primarily converted to agriculture, urban areas, and mining.
- The MapBiomas initiative, formed in 2015, uses machine learning to produce 40 years of land use data in six months.
- Annual maps are created by mosaicking satellite images and classifying land use, showing pixel-level transformations over decades.
- The system validates deforestation events using high-resolution imagery and cross-references with land data to generate legal reports.
- MapBiomas produced 2,000 deforestation reports weekly in 2023, a significant increase from under 1,000 reports by agencies in 2018.
- This led to a 54% rise in enforcement actions against illegal deforestation between 2019 and 2024.
- Financial institutions denied $1.5 billion in financing to 30,000 farms with detected deforestation, redirecting funds to sustainable operations.
- MapBiomas data serves over 600,000 users for applications including disease prevention, water management, and protecting indigenous rights.
- In 2023, the Brazilian government used MapBiomas data to identify 3,000 airstrips near illegal gold mines, reducing miners on indigenous lands by 90%.
- The MapBiomas Network plans to expand mapping to 70% of the world's tropical forests by 2030, supported by TED's Audacious Project.
