Symposium NWA Living labs for the restoration of rural biodiversity
Under the banner of the National Science Agenda, a broad programme of three living labs and an umbrella project started in 2021. During the symposium at Hotel Zuiderduin (Egmond aan Zee), interim results of the research programme will be presented, two external keynote speakers will share inspiring experiences and there will be time in the workshop sessions to reflect and give input. -
Dealing with bluegreen algae
Worldwide, excessive nutrient loads in lakes and reservoirs have led to the rapid increase of harmful cyanobacteria. Blooms of these algae block the use of surface water for drinking, irrigation and recreation. Climate change is expected to further increase the frequency, duration, and magnitude of cyanobacterial blooms. Aquatic ecologists from NIOO are busy gaining more detailed insights into cyanobacterial blooms across scales, in future climates and in respect to toxicity. -

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.
