This article describes the creation of an app that can help raise climate awareness and the action globally.

Almost 100 billion tons of CO₂ could be pulled out of the atmosphere by the end of the century. That is, if high-income countries switch to a plant-based diet. The double carbon profit of returning farmland to its natural state would equal about 14 years’ worth of agricultural emissions, researchers…

On Friday 10 July the Towards Biosolar Cells research programme was granted a budget of 25 million euros by the Dutch Government. The Ministry of Agriculture, Nature and Food Quality recommended the programme because it will contribute to green energy, improve food supplies and a create a more sustainable…

Anthropogenic noise has been shown to affect marine animals in various ways, this may have fitness consequences at individual and population level. This thesis aims to increase insight into the quantification of sound-induced behavioural responses that are relevant to fitness, and into factors that…

After decades of intensive farming, the peatland area is under pressure. Researchers, farmers and policymakers work together in the Polderlab to identify future-proof types of agriculture. ‘It’s unbelievable how quickly the system bounces back without intensive fertilisation.’

Globally and regionally, biodiversity is declining and there are shifts in species’ occurrences and functional traits.
