The loss of tropical forests is often in the news. We see pictures of barren land next to forest, of chainsaws, of bulldozers. Depressing images. These new items generate frustration and anger, among politicians, conservationists, scientists and many more. We are frustrated by the loss of ecosystems that are so vastly diverse, that generate rainfall […]

This essay analyses the current backslash relating to the EU Green Deal and identifies four distinct explanations for it (changing political mood, Baptists-Bootleggers politics, planned implosion, and counter mobilization). It then argues for three main changes needed to strengthen EU nature policy: 1) more transparency, including the assessment of trade offs, 2) more participation, and

Biodiversity is a broad concept, often difficult to grasp. Nonetheless, our research on biodiverse consumption shows that people value biodiversity and wish to protect it. But what is the best way to do this, and what influence does one consumer have in a system that seems to be ruled by profitability? These questions arise when

The Netherlands is famous for many of its domesticated plant exports, not least tulips but also vegetable seeds. Together with plant breeders, we are researching into how to breed for crops that are adapted to more biodiverse growing conditions (e.g. intercropping, where more than 1 crop species is simultaneously cultivated). Biodiversity in agriculture has been

As an ecologist and (soil) biodiversity scientist, I am always interested in nature. But I also see the need for food, and therefore agriculture. What I long did not understand is that many kids nowadays do not even know how their very basic food, like potatoes grow. What I was also surprised about and learned
Wat een regen hebben we de afgelopen maanden gehad. Ik krijg regelmatig de opmerking dat het neerslagtekort nu inmiddels toch wel weer aangevuld moet zijn. Daarin spreekt de hoop dat daarmee het effect van de extreem droge en warme periodes in voorgaande jaren weer teniet is gedaan. Helaas. Massale sterfte door extreme weersomstandigheden compenseer je

The climate crisis and enormous decline in biodiversity present Europe with two scenarios. Or Europe will continue as usual and create an even greater separation between man and nature, with all the consequences that entails. Or European people work together with nature, exchange concrete for respect for the landscape, and let nature guide the design

Natuur in de stad is van groot belang voor onder andere biodiversiteit, waterretentie, hittestressbestrijding, sociale cohesie en om mensen in beweging te krijgen. Kortom, natuur is belangrijk voor een prettig leefklimaat. Hoe krijg je dat voor elkaar? De gemeente Arnhem heeft met de wijkgroenagenda-aanpak daarvoor een goede aanzet gegeven. Eerst kijken waartoe de wijkbewoners zelf

One of the most compelling figures I saw over the last few years is the one where the total weight of all mammals on earth, so all elephants, whales, rhinos, deer, cats, dogs, cows, pigs, humans, and the rest are compared to the weight of the separate categories. The outcome (see https://ourworldindata.org/wild-mammals-birds-biomass): Livestock make up

You can often find me in wet, muddy and beautiful ecosystems: wetlands! I work in peatlands, fresh and salt marshes, mangroves, seagrass meadows and bivalve reefs. Such wetlands are home to unique biodiversity. Here, species are adapted to wet, sometimes acidic, salty or dynamic environments. Importantly, wetlands are often dominated by ecosystem engineers: species that
