  • Bridging the gender gap through groundwater monitoring in a Rajasthan village

    A group of farmers in India have been trained to monitor their village’s groundwater levels to help its residents make more informed decisions about irrigation based on water availability. The farmers-turned-researchers are known as “Bhujal Jaankars” and they monitor rainfall, dam water levels, and water quality to notify residents so they can plant crops that don’t require a lot of water. While there is a lack of gender diversity in the group, they are working on developing training to include more functional literacy skills to encourage participation from others.

  • Ecosystems-based adaptation keeps water running in Bhojdari even in dry months

    Bhojdari, a town in India, faced a severe drought in the early 2000s. The town doesn't have a river or canal nearby. However, after implementing an ecosystems-based approach, the town has reliable access to water, even in the dry months. Some of the methods that were incorporated in this approach included the creation of irrigation models, planting bamboo trees, and creating fish ladders so that fish can move up the stream.

  • Can the forests of the world's oceans contribute to alleviating the climate crisis?

    A researcher in Tasmania is working to create climate-resilient “super-kelp” that could survive in its new climate along the coastline and help absorb carbon to prevent it from being released into the atmosphere. Other conservationists around the world are using different techniques to revitalize its diminishing kelp forests. In California, they have hand-cleared 52 acres of invasive purple urchins from the seas to bring back its kelp forest. While kelp can be tricky to work with, rebuilding these forests is one way to combat climate change.

  • How tech is tackling wildlife trafficking

    Three examples of new science behind successful efforts to prevent or punish the poaching of protected wildlife starts with PAWS: Protection Assistant for Wildlife Security, an artificial intelligence tool that helped officials in Cambodia predict where poachers would set snares.

And Kenya prosecuted four cases of pangolin trafficking by using a new method of lifting fingerprints from the poached animals' precious scales.
