In recent years, periods of extreme drought and extreme rainfall have alternated at a rapid pace. It is getting wetter and drier. With consequences for nature, agriculture, our dikes, our houses and ultimately for ourselves. The question is: how do we keep the Netherlands wet, but not too wet? These questions were discussed in the podcast 'De Oplossers' with amongst others IBED professor Annemarie van Wezel.

Photographer and film maker Jan van IJken made the 'Planktonium', about the misterious world of plankton. IBED researcher Katja Peijnenburg tells about these tiny creatures on radio Vroege Vogels.
Storing carbon in the soil will not save the climate
The principle seems simple: carbon stored in the soil is not released into the air as the greenhouse gas CO2. But how big is this contribution? Too small to stop climate change. It makes more sense to look at the organic fractions in the soil, which sometimes take decades to break down. Keeping farmland covered with vegetation all year round, not tilling it too intensively, catch crops and green manure crops all contribute to retention of organic matter and nitrogen, that other elephant in the room. 'No plants, no nitrogen uptake,' says Professor Franciska de Vries.
Mummified dung as a photo of a landscape
For more than a century, it collected dust in a drawer in the museum.

In recent years, ecologists from the Royal Netherlands Air Force, KNMI and the University of Amsterdam (Judy Shamoun-Baranes) have recorded unusual flights of thousands of birds on New Year's Eve on radar, where you can see birds taking flight in response to fireworks. If fireworks are set off all over the country at the same time, the birds have nowhere to go.
A sloth turd, turned during the last ice age, reveals its secrets
'With an apple drill, I took a piece of the turd with a diameter of one and a half centimetres,' says Bas van Geel. 'From that, I was able to prepare intact pollen grains. (...) The giant sloth turned out to have eaten a meal of lots of strawberries and cushion plants!'
Both Guinea baboon males and females take the lead

In this article, Franciska de Vries and colleagues briefly explain what the concept entails and why it has become so important.
A water filter for cleaner and safer tap water? No need for it
The popularity of water filters seems to be increasing in the Netherlands. According to the manufacturers, they purify tap water of heavy metals and bacteria. Experts, such as Annemarie van Wezel, unanimously reject the devices. It is pure deception.
Seagulls on Forteiland
In the entrance to the Noordzeekanaal near the port of IJmuiden lies an island: Forteiland. Here a gigantic gull colony with about a thousand pairs of lesser black-backed gulls and about a hundred herring gulls breeds. Since 2019, Rosemarie Kentie has been collecting feather and blood samples from herring gulls and lesser black-backed gulls that breed on Fort Island. By looking at the composition of the blood, Rosemarie can determine whether gulls have eaten food from the sea or from the land.

What does a seagull eat?
To answer this question you can look at the vomit balls, with undigested fish remains (or spare ribs) that you find next to a gull's nest. But it can also be done in a modern way, says IBED researcher Roos Kentie in Vroege Vogels: 'The type of food of a gull, land or sea, high or low on the food chain, leaves its mark in the bird's blood!'
'We have to make nature resilient to climate change'
You wouldn't say it these days, but in recent years the Netherlands had warm and dry summers in due to climate change. The prospect is that this will happen more often.

IBED professor Annemarie van Wezel explains on EenVandaag why she is critical regarding the current authorization policy for new pesticides.
Court decision may have major consequences for the use of pesticides near nature reserves
A ruling by the court about the use of pesticides near a protected nature reserve in Drenthe could have major consequences for the use of pesticides in the rest of the country.

In a new study in PNAS, researchers determined that a rainforest in the Putumayo region of Peru has been home to relatively unaltered forest for 5,000 years, meaning that the people who have lived there found a long-term way to coexist with nature–and the evidence is in microscopic bits of silica and charcoal in the soil. Bioengineer.org reports about this study that was co-authored by UvA resaerchers Crystal McMichael and Britte Heijink.
Stricter rules needed to contain the spread of harmful PFAS
