Koning bezoekt NIOO op 6 juli
Zijne Majesteit Koning Willem-Alexander brengt op woensdagmiddag 6 juli een werkbezoek aan het Nederlands Instituut voor Ecologie (NIOO-KNAW) in Wageningen. -
Microbial Networks controlling soil greenhouse gases emissions
Soils are considered principally non-renewable resources. Soil ecosystem services have a large impact on numerous societal demands and are of high economic importance. Within the area of sustainable agriculture, it is expected that agricultural production will increasingly rely on the natural nutrient retention and recycling capabilities of soil. This project seeks to provide a fundamental scientific understanding of soil functioning and the resulting ecosystem services in Brazilian and Dutch bio-economies based on innovative microbial ecology and soil science studies. Focus is in sugarcane crop production systems by linking soil microbial composition and functioning, waste residues recycling, fertilizers, soil factors and greenhouse gases (GHG) emissions through integrating and complementing the strong expertise of Brazilian and Dutch researchers from different areas of agronomy, soil sciences, plant nutrition, biogeochemistry, soil ecology, microbial ecology, ecological genomics, molecular ecology and bioinformatics. We will quantify the microbial functional groups and microbial abundance of C and N cycle genes and measure GHG emissions (CO2, CH4 and N2O) from soils during the productive cycle of the plant under different management practices and verify the temporal and spatial variability of these emissions in the evaluated treatments with different concentrations of sugarcane vinasse residue combined with N mineral fertilizers in combination with straw additions, and determine the conditions under which such GHG emissions can be counteracted, or minimized most. The proposed project will enhance fundamental scientific understanding of the interactive role of the microbial networks operating in soil and the consequences of bio-based agricultural management practices for the functioning of soil systems. -
Large herbivores can bend the curve of biodiversity loss in tropical forests
A 10-year experiment in Brazil’s endangered Atlantic Forest, led by NIOO-researcher Nacho Villar, has found that there's less biodiversity loss in areas where large herbivores can roam free. -
Minder biodiversiteitsverlies in bedreigd bos door grote grazers
In bosgebieden met grote grazers is er minder biodiversiteitsverlies. Dat is de conclusie na een tienjarig experiment in Brazilië, geleid door Nacho Villar. -
"Rewilding landscapes can help to solve more than one problem"
Urbanisation, biodiversity loss, climate change: just some of the worldwide problems 'rewilding' - i.e. restoring food chains by returning 'missing' species to the landscape - can help tackle -
"Wilde dieren terugbrengen in een landschap kan meer dan één probleem oplossen"
Het gericht ‘verwilderen’ van het landschap, waarbij je voedselketens herstelt met het terugbrengen van dieren, kan een hoop wereldwijde problemen helpen aanpakken. -
Loss of soil carbon due to climate change will be "huge"
55 trillion kilograms: that's how much carbon could be released into the atmosphere from the soil by mid-century if climate change isn't stopped. And all in the form of greenhouse gases such as CO2 and methane. Tom Crowther (NIOO-KNAW) and his team are publishing the results of a worldwide study into the effects of climate change on the soil in the issue of Nature that came out on 1 December. -
Toch enorme uitstoot broeikasgassen door opwarming bodem
Vijfenvijftig biljoen (12 nullen!) kilo koolstof. Zoveel zal er in 2050 vanuit de bodem extra de lucht in zijn gegaan bij aanhoudende klimaatverandering. En wel in de vorm van broeikasgassen zoals CO2 en methaan. Dit toont onderzoeker Tom Crowther van het Nederlands Instituut voor Ecologie (NIOO-KNAW) met zijn team aan in een wereldwijd onderzoek naar het effect van klimaatverandering op de bodem. Donderdag 1 december publiceerde het tijdschrift Nature de resultaten.
