Biodiversity Articles

NASA has numerous datasets and resources for monitoring biological diversity. The Biological Diversity Toolkit provides direct links to those datasets, related webinars on using the data, and data recipes and tutorials. Forthcoming, a Biological Diversity and Ecological Forecasting Data Pathfinder, geared for new users, will provide direct links to commonly used datasets and links to tools for visualizing and analyzing the data. Read Harnessing Remote Sensing Data for Biological and Ecological Research to see how NASA data are being used in research applications.

Over half of the world’s biodiversity has disappeared since 1970, according to the World Wildlife Fund Living Planet 2018 Report, largely due to human interactions with the environment. Biologists, ecologists, and wildlife and conservation managers around the globe are conducting research into why this change is happening at an unprecedented rate, the impacts of this change, and ways to conserve these vital natural resources. With the information acquired from both ground-based and satellite-based data, decision makers are able to monitor and respond to changes in biodiversity.

These articles, many from the Sensing Our Planet series, highlight some of these efforts. To meet some of the scientists using Earthdata for ecological research and applications, see our Data User Profiles.
