On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
Groundwater irrigation is increasingly important in agricultural production, nearly tripling since records began in 1950. Increased reliance on groundwater and prolonged unsustainable pumping of aquifers has led to groundwater depletion in many areas. Yet, irrigation enables producers to buffer agricultural production and supply chains against weather risks, such as drought. This talk will examine the relationship between groundwater irrigation, agricultural production, and supply chains. Specifically, the role of groundwater irrigation in the food supply chains of the United States and China, two key countries in the global food trade, will be presented.
