Scientists are growing seeds in space to help adapt to climate change on Earth
Plants naturally adapt to grow in challenging environments. Spontaneous natural mutations produce new traits, such as drought tolerance and disease resistance, which can help the plant to thrive. But the Earth’s climate is changing faster than plants can naturally evolve, meaning that many of the plants we rely on for food are under threat.
“Firstly, we are working on improving crop yields and productivity of crops such as grains, legumes, roots and tubers – for example, cassava and sweet potato,” she says. “And then there is climate change resilience – for example resistance to increasing incidence of diseases, tolerance of climate phenomenon such as drought, or high heat, and increasing salinity of the soil because of saltwater intrusion or irrigation and evaporation.
