The National Geographic Society seeks proposals addressing environmental issues by communicating science. The NGS seeks proposals from around the world that advance the science of nature communication by systematically testing visual communication and education methods. The call is intended for visual artists, photographers, and videographers who aim to more effectively create and use images or video to overcome apathy towards species and ecosystems. Typical proposal requests should be less than US$30 thousand, but applicants may request up to US$50 thousand. The current grant cycle closes 10 April 2019. Details here
