Satellites Help Track Biodiversity, But Gaps Remain

Topic: Environment

Scientists used satellites to monitor biodiversity and found that they can track changes in ecosystems. However, there are still many things that cannot be observed from space.

A new study published in Nature Reviews Biodiversity shows how satellites and other remote sensing technologies are changing the way we monitor biodiversity. The review was led by Dr. Jesús Aguirre-Gutiérrez, an associate professor at the University of Oxford's Environmental Change Institute (ECI).

The study focused on a big challenge for countries reporting under international nature targets: how to measure and report on the state of biodiversity across large areas. Tropical forests are a critical case study because they contain a lot of global biodiversity and are affected by climate change, land-use change, and disturbance.

Satellites can provide information on forest structure, biomass, canopy traits, and ecosystem functioning. This data helps researchers understand how forests resist, recover from, and adapt to environmental change. However, satellites cannot yet provide a complete picture of biodiversity. Many important dimensions, including species turnover, evolutionary history, and genetic diversity, remain difficult to observe directly from space.

The study emphasizes that satellite observations must be integrated with ground-based ecology to produce robust and reliable biodiversity assessments.

Why It Matters

This research is important for India because it can help us understand how to protect our forests and wildlife. As the country develops, we need to make sure that we are not harming our environment.
