Illegal fishing and rampant deforestation are two of the most pressing environmental crimes facing the world today. Not only do they endanger ecosystems and biodiversity, but they also undermine food security, accelerate climate change, and destabilize coastal and rural economies. Fortunately, a new wave of technology is giving conservationists, governments, and global organizations a powerful new tool: satellites.
From orbit, satellites provide a bird’s-eye view of Earth’s oceans and forests, making it possible to monitor vast areas in real time and detect illegal activity as it happens. With improvements in imaging resolution, cloud computing, AI, and public-private partnerships, satellite surveillance is revolutionizing environmental protection on a global scale.

Fighting Illegal Fishing with Eyes in the Sky
Illegal, unreported, and unregulated (IUU) fishing accounts for up to 26 million tons of fish caught annually, threatening marine ecosystems and costing governments billions in lost revenue. Traditional marine patrols are expensive, slow, and limited in range—but satellites can cover thousands of square kilometers every day.
Key satellite techniques combating illegal fishing include:
- AIS (Automatic Identification System) Tracking
Ships are required to transmit their location using AIS. Satellite systems track these signals, and sudden disappearance or erratic movement can indicate illegal activity. - SAR (Synthetic Aperture Radar)
Even when ships turn off their AIS to “go dark,” satellites equipped with SAR can still detect them through cloud cover and at night. - AI-Based Vessel Pattern Analysis
Machine learning models analyze movement patterns, fishing gear types, and location histories to flag suspicious behavior in near-real-time.
Platforms like Global Fishing Watch, SkyTruth, and ORBCOMM are already providing open-access tools to governments and NGOs to track vessels and detect illegal fishing hotspots globally.
Deforestation Detection from Space
The rapid destruction of tropical rainforests for agriculture, logging, and mining is a major driver of climate change and biodiversity loss. According to Global Forest Watch, the world lost over 11 million hectares of tropical forest cover in 2023 alone.
Thanks to satellite technology, deforestation can now be tracked with extraordinary precision and speed:
- Multispectral & Hyperspectral Imaging
Satellites like Sentinel-2, PlanetScope, and Landsat 9 use various wavelengths to detect vegetation loss, land cover change, and soil degradation. - Near Real-Time Alerts
Platforms like Global Forest Watch, Rainforest Connection, and NASA’s FIRMS deliver near real-time alerts when deforestation occurs, allowing authorities to act faster. - AI & Big Data Integration
AI algorithms sift through petabytes of imagery to detect illegal logging patterns, road expansions, and even the start of forest fires.
By monitoring forests from space, local communities, journalists, and governments can hold companies and corrupt officials accountable for land grabs and unauthorized clear-cutting.
Collaborations Driving Impact
The power of satellite monitoring lies not just in the tech, but in the partnerships enabling it. Governments, conservation NGOs, and tech companies are working together to democratize access to satellite data:
- Global Fishing Watch is a collaboration between Google, SkyTruth, and Oceana.
- Global Forest Watch is backed by the World Resources Institute and receives data from NASA and ESA.
- Satelligence and Planet Labs partner with palm oil companies to detect deforestation in supply chains.
These platforms promote transparency and empower local enforcement units with data that was once available only to wealthy nations or militaries.
Future of Satellite Conservation
As satellite technology advances, costs are dropping and resolution is improving. By 2026, experts predict commercial satellites will be capable of imaging every corner of the Earth daily, enabling even more precise environmental monitoring.
In addition, AI-powered automation, blockchain data integrity, and drone integration will enhance satellite capabilities, offering real-time environmental intelligence to even the most remote regions.
Conclusion
Illegal fishing and deforestation are no longer crimes that can hide in plain sight. With a fleet of satellites orbiting above, we now have the tools to track, report, and fight environmental damage more effectively than ever before. By combining cutting-edge satellite tech with global cooperation and on-the-ground action, humanity has a fighting chance to protect the planet’s forests, oceans, and biodiversity for generations to come.
