Building Bridges – establishing effective collaboration networks
Download as PPTX, PDF0 likes411 views
The document discusses the establishment of effective collaboration networks in agriculture, hydrology, and soils. Key points include the accuracy of evaporation and transpiration predictions, the relationship between soil moisture deficit and runoff, and the timing of nitrate and pesticide pollution in rivers. Additionally, it emphasizes the importance of accessible and usable data for informed discussions and decisions.
Building Bridges – establishing effective collaboration networks
- 1. Building Bridges – establishing effective collaboration networks Bob Evans Visiting Fellow Global Sustainability Institute Anglia Ruskin University Cambridge
- 2. Building Bridges Other side bridge – who? Agriculture, soils, hydrology Do they want to talk? Dialogue Common ground
- 3. Some thoughts Three points: • Glad we didn’t get it wrong • What happens to the rain? • Access to data
- 4. Glad we didn’t get it wrong PSMD + AWC Anon Anon CUCAP
- 5. Glad we didn’t get it wrong - BUT • Do evaporation and transpiration occur at predicted rates (e.g. Maff Tech Bull 1967) or do constraints kick in(e.g. MORECS)?
- 6. What happens to the rain? • Can Potential Soil Moisture Deficit explain: – When Runoff occurs – When Drains flow – Stream flow Copyright Evans 2013 Copyright Evans 2013
- 7. What happens to the rain? • When do nitrate and pesticides reach rivers? Wissey stream flow to PSMD 2003-2008 r = c. - 0.7 (range - 0.5 to -0.9) Metaldehyde in rivers Max value 2.4 ug/l Data supplied by Environment Agency Anglian water
- 8. Access to Data • NEED to mine the data • FREE access to Data • EASY access to Data • Easily useable Thank you
