Insects, bees and plants interaction

Pollinators are needed, large parts of agriculture and world food production are heavily dependent on pollinating insects. Still, the number of wild pollinators is declining, but there is still something that can be done to stop the development. It requires new cultivation and beekeeping strategies, but it can be done.

Machine learning creates ways to better assess the suitability of agricultural land

A comparison of maps of land suitability for specialty crops produced using machine learning and a mechanistic crop model gives rise to rethinking the concept of “suitability” and perhaps even replacing it with the two concepts: ecological suitability and socioeconomic suitability.

Plant-based dye from carrots can replace synthetic color in the foods we eat

Researchers from, among others, the Department of Agroecology at Aarhus University have found a method by which mechanisms can be activated in orange carrots so that they produce more anthocyanin dye, which can replace synthetically produced dyes in food. It provides new opportunities to replace synthetically produced dyes with plant-based natural…

More grassland to improve climate and environment

Grassland areas may reduce agricultural emissions of greenhouse gases and nutrients. Together with newly developed biorefining technologies, grasslands constitute a breeding ground for new sustainable products, e.g. green protein to replace the use of imported soya. A new research project will make it possible to harvest the benefits.
