Impact of nutrients
Nutrient availability in natural ecosystems has increased due to anthropogenic activities like spill-over from agricultural ecosystems. In the Netherlands, this has led to the acidification of natural areas for example. At NIOO, we aim to understand the impact of nutrients on natural systems in more detail, to help to bring back the balance. -
Climate change impacts on harmful algal blooms
Harmful cyanobacterial blooms produce toxins that are a major threat to water quality and human health. Blooms increase with eutrophication and are expected to be amplified by climate change. Yet, we lack a mechanistic understanding on the toxicity of blooms, and their response to the complex interplay of multiple global change factors. Bloom toxicity is determined by a combination of mechanisms acting at different ecological scales, ranging from cyanobacterial biomass accumulation in the ecosystem, to the dominance of toxic species in the community, contribution of toxic genotypes in the population, and the amounts of toxins in cells. -
Book presentation on Water farming
On Friday afternoon 29 September, a new book about Water farming will be presented at NIOO. NIOO scientists Ellen Weerman and Ellen van Donk are two of the editors, and you are very welcome to join. The presentation will be in Dutch. -

ClipsMicro: Climate proof soils by steering soil and residue microbiomes
To mitigate climate change, global agricultural soils needs to store more carbon and emit less greenhouse gasses (GHG). In ClipsMicro, together with partners in agro-business, this is realised by steering soil microbes by application of novel, refined compost and crops that can reduce emissions of GHG. -
New lectureship on 'climate-robust' landscapes connects nature and agriculture
A new research group set up by NIOO and HAS University of Applied Sciences is asking how alternative forms of agriculture can improve water quality and biodiversity. -
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. -
NIOO Theme Climate change
We are in the midst of a climate crisis. Our climate system is undergoing a dramatic number of changes, many of which can be attributed to anthropogenic influences, including greenhouse gas emission-induced changes to global surface temperatures, precipitation, glacier mass loss, sea levels, salt intrusion, and ocean heat content.
