Historic Droughts: Using the past to inform the future

Lucy Barker (UK Centre for Ecology & Hydrology) presents on a number of cutting edge aspects of drought science.

Climate change projections indicate that extreme events will increase in their frequency and severity in the future.  An improved understanding of the drought events of the past can inform current and future management. In this talk, Lucy demonstrates how reconstructed river flows have enabled consistent, national scale characterisation of historic hydrological droughts and how access to current and historic data can support ongoing drought monitoring activities.

The work originates from a number of projects including Historic Droughts and the About Drought programme and you can view the talk below.

This talk is part of the British Hydrological Society webinar series, “Future Hydrology in a Changing Environment”. You can view past webinars on their YouTube channel.

Informing the water industry & Environment Agency

“About Drought has informed the water industry, now we need some sort of mechanism to identify the most useful outputs from strategic to operational products. We must not let those fall through a crack now that About Drought has finished.”

“About Drought has helped generate a step change in thinking around what is possible and what can be done, and over the next 10 years or so we will be making better decisions, using better tools because of it,” says Paul Crockett who is leading the modelling work on the National Water Resources Planning Framework for the Environment Agency.

Yet Paul, who has worked closely with the MaRIUS project and About Drought (ENDOWS), believes there is still more to be done in encouraging the water industry to catch up with the latest outcomes of the programme’s data and tools.

Real-time decision-making support for the water industry

About Drought has supported the water industry in both strategic planning and real-time decision-making during a time when it has come under pressure to collaborate across water company boundaries on regional forward planning, as well as approaches to dealing with issues as they arise with a greater level of accountability.

MaRIUS and ENDOWS have held a series of workshop events specifically for the industry, working alongside key stakeholders to match its research to their needs.

With the National Water Resources Planning Framework driving water companies to work together to build resilience into water management with clear, joined-up direction from Government departments, agencies and water regulators, the industry is now more ready to be receptive, Paul feels.

He says: “There are a lot of great products from MaRIUS and About Drought but the water industry – the customer, if you like – is only just seeing the potential.”

Improving the industry’s understanding of statistics

Historic Droughts’ work in reconstructing reliable rainfall, river flow and groundwater data back to 1890, as well as providing standardised drought indices has been important in putting events into context, improving the industry’s understanding of statistics, the latest methodologies and stakeholder needs. There is still more to be done in migrating data from the academic models to those the water companies use.

The water resource model developed by MaRIUS is being adopted for use by Paul’s team, to help the National Water Resources Planning Framework assess the potential effects of different types of drought and climate change impacts at a national scale, and test management strategies.

Giving the water industry better knowledge and insights

Paul’s concern is that with the impacts of climate change starting to be felt on the reliability of water availability, it is the wrong time to bring About Drought to an end. He says: “It’s so important to have About Drought following on from the original research projects; it demonstrated what is possible, the better knowledge and insight we can get from the information that decisions will be based on in the future. The team really helped to educate the industry rather than just educating other academics.

“We need to look at the tools we can use to take it even further forward now that the industry is starting to buy into it more.

“About Drought has informed the water industry, now we need some sort of mechanism to identify the most useful outputs from strategic to operational products. We must not let those fall through a crack now that About Drought has finished.

“About Drought is to be applauded for what it has done but it needs more time and resources if it is to maximise the outcome for UK plc of all this research.”

Drought impacts explorer

As part of the Historic Droughts project, researchers at Cranfield University developed an inventory of qualitative drought data related to UK agriculture based on an extensive review from two weekly farming magazines in the UK, Farmer’s Weekly and Farmers Guardian for the period 1975-2018. The resultant inventory contains over 2500 records with information on the start and end dates of the event and their location to characterise the temporal and spatial extents of the cited event, together with the text describing the driver, impact or response in relation to that event. The inventory is available to download as a csv file from the UK Data Service.

This dataset is also currently being translated in to a drought impacts explorer, which allows the user to view these records spatially and to search and save according to various criteria. If you would like to be involved in beta testing of the explorer please contact nevil.quinn@uwe.ac.uk. An early draft of the explorer is available online.
