Researchers found that intercropping, an ancient Maya farming technique, is effective in nutrient-poor Martian soil.
The study suggests that intercropping can improve crop yields and combat the impacts of climate change on Earth.
There are challenges in adapting space agriculture techniques to regions most in need due to existing power inequalities.

Why this matters: As climate change degrades arable land, finding sustainable agricultural practices is crucial for global food security. Techniques developed for extraterrestrial farming could help restore Earth's depleted soils and ensure a reliable food supply.
Afforest for the Future is one of a series of projects trying to create arable land from sand. Its method: use the muck that collects behind dams to create new soil.
