DSD-INT 2019 DANUBIUS-RI the Scientific Agenda-Bradley

  1. 1. DANUBIUS-RI: the Scientific Agenda. 1Chris Bradley, 2Jana Friedrich, 2Sina Bold & 3Andrew Tyler 1 2 3
  2. 2. US National Park Service
  3. 3. Environmental challenges (River Thames) • High population density / population growth / increasing water demand • Water stress / drought • Flooding • Groundwater polluted with nitrate from farming • Algal blooms • Invasive species
  4. 4. • Provide real / near real time observations of: • Water Quality • Emerging Pollutants • Biogeochemical cycling • Land cover • Change detection (phenology) • Validate EO data • Coordinate fixed and mobile sensor deployment • Coordinate biogeochemical sampling for satellite and in-situ sensor validation • Dealing with structured and unstructured data (Big Data Issues) Observation Capabilities
  5. 5. • Practicalities of standardizing approaches across the freshwater & marine sciences; • But: • Enormous opportunities to harness recent advances in in-situ sensors and earth observation; • What are the minimum no. of parameters needed to characterize a particular catchment; • What is the ideal sampling / observation frequency • [Modelling challenges……?!]
  6. 6. Enhancing process and system understanding: How are ‘River - Sea systems’ changing due to different pressures? How are they interacting? How are processes and changes on land affecting those in rivers and seas and vice versa? How are processes and changes in the headwaters affecting those further along the River Sea continuum? How are these changes affecting ecosystem functioning and services? How can we sustainably manage River Sea systems?
  7. 7. The Approach 7 River-Sea (RS) System Geosphere Atmosphere Ocean River Basin Coastal, Sea Estuary, Delta water, sediment, dissolved and particulate matter, organisms Land
  8. 8. The Approach: 8 • mission-oriented and problem-solving to address environmental and socio-economic challenges related to RS systems • considers change(s) and resilience of RS systems • advances an integrated approach for studies of RS systems and regards RS systems as social- ecological systems • enables interdisciplinary research and innovation • promotes a participatory approach including engaging various stakeholders and public(s)
  9. 9. Our Research Themes 9 1. Climate Change (e.g. sea level rise, change in temperature and precipitation, extreme events) 2. Water Quality & Quantity (e.g. changes in hydromorphology, eutrophication, pollution) 3. Sediment Quality & Quantity (e.g. erosion, pollution, connectivity issues) 4. Ecosystem Health (ecosystem structure & functioning; e.g. biodiversity, habitat change/loss, invasive species, overfishing, pollution,) 5. Living with Change (climate change and other human drivers; e.g. nature based solutions)
  10. 10. Achieving Healthy Inland, Transitional & Coastal Waters Water Quantity: understand water stores and fluxes across the River – Sea continuum 1. How can we quantify water storage, flows and residence times (and their spatial and temporal variability and connectivity) 2. How can we predict upstream – downstream impacts of man-made changes in hydromorphology (on ecosystem functioning & biodiversity) 3. How can we manage competing demands for water resources (to sustain healthy River – Sea systems) Global Freshwater Use 0 2000 4000 6000 1600 1700 1800 1900 2000 2100 Withdrawals(km 3 )
  11. 11. Sediment balance: understand and quantify sediment dynamics from Source – to – Sink (and manage sediments sustainably) 1. How do man-made changes in hydromorphology alter sediment regimes – and what are their consequences? 2. How can we improve estimates of sediment budgets (for River – Sea systems) to enable better management? 3. How can nature-based solutions support sustainable management of sediments? 4. How can we restore engineered rivers, transitional & coastal waters while retaining key socio-economic functions Achieving Healthy Inland, Transitional & Coastal Waters
  12. 12. Nutrients & Pollution: understand the effects of Nutrients & Pollution in water and sediment 1. What are the sources, pathways, transformations & sinks of nutrients and pollutants from current and legacy sources; 2. How does upstream eutrophication & hypoxia impact downstream ecosystems (in estuaries / coastal seas) 3. What are the thresholds for single and multiple pollutant exposures upstream 4. How can we detect new and emerging pollutants and assess their impacts? 5. How can we integrate new economic strategies to mitigate, control & manage pollution across River – Sea systems. Achieving Healthy Inland, Transitional & Coastal Waters Steffan et al. 2015
  13. 13. Biodiversity: 1. Assess & predict changes in biodiversity and ecosystem functioning 2. Risks of invasive species? 3. Causes of changes in Ecosystem structure & functioning 4. Importance of longitudinal & lateral ecological connectivity Achieving Healthy Inland, Transitional & Coastal Waters Ecosystem Services: 1. Importance of biodiversity & ecological processes in sustaining ecosystem services? 2. Consequences (for ecosystem services) of multiple pressures on River – Sea systems? 3. How can we avoid over- exploitation of ecosystem services?
  14. 14. Summary & Outlook • provides access to long-term research infrastructure along several RS systems enabling interdisciplinary research • uses standardised methods and provides access to comparable data • synthesizes existing knowledge on RS systems and enhances process and system understanding • informs and facilitates the joint implementation of European (WFD, MSFD, FD etc.) as well as global (SDGs) water related policies • Science & Innovation Agenda being published in Nov. 2019 14
