Beter inzicht in concurrentiestrijd tussen microben in bodems en oceanen
Vooral neerslag en bodemzuurgraad bepalen welke microben in een bepaalde habitat overleven en welke niet. Deze kennis is van belang om de biodiversiteit in stand te houden. Leidse milieukundigen werkten mee aan het onderzoek. Publicatie in Nature op 1 augustus.

Monitoring drought and salinity stress in agriculture by remote sensing for a sustainable future
Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

Unsprayed field margins: effects on environment, biodiversity and agricultural practice
A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…
