Day 2: Parallel Session 1 Drought Planning & Management – The Pichette Auditorium<br />

Lindsey McEwen UWE & DRY<br />

Integrating science and narratives: a new interdisciplinary approach to develop drought mitigation<br />

strategies<br />

Drought - a diffuse, slowly progressing and pervasive hazard - is a complex ‘high stakes’ risk that is increasing in the<br />

Anthropocene. As a natural phenomenon, drought can happen anywhere at any time, while also socially constructed<br />

through overuse of water supplies. Issues exist in using specialist science as the dominant evidence- base in: framing of<br />

drought risk communication as “knowledge deficit”; managing drought risk; and mitigating actual droughts. This<br />

presentation explores how, and by what processes, scientific and narrative evidence on drought risk and drought<br />

mitigation might be brought together to support better decision-making for UK drought risk management (DRM) and<br />

more widely. It provides a methodological review of critical points of connection between science and narrative<br />

within the interdisciplinary DRY project (Drought Risk and You), exploring issues that we have had to address in<br />

developing our methodology to innovatively “bridge the knowledge gap”. This paper appraises the decisions in<br />

bringing narrative and science iteratively into the same space as DRY’s “engaged”, participatory methodology has<br />

played out, set against opportunities and barriers for drought risk communication and the nature of “narratives”. We<br />

explore potential for science-narrative interaction in terms of “past”, “present” and “future” drawing across<br />

exemplars from different methodological concerns: conceiving narrative as data and data as narrative; working with<br />

science as stimuli for narratives (and vice versa); interdisciplinary and inter-professional systems thinking; exploring<br />

roles of visualisation in risk and complexity; co-developing “bite- sized drought science”; scenario-ing to bring<br />

narrative and science together in iterative engagements; co- developing local catchment-based drought impact indices;<br />

and co-designing DRY’s “Utility” that draws on science and narrative to support better multi-stakeholder decisionmaking.<br />

This requires cognisance of different ways “evidence” could be used in DRM, building up from individual<br />

household level to non-statutory and statutory organisational decision-makers.<br />

Miranda Foster & Granville Davies Yorkshire Water<br />

Water resources in Yorkshire, UK in <strong>20</strong>18: drought management, perception and communication<br />

<strong>20</strong>18 was an interesting year for water resources management in Yorkshire. Although we are considered to be one of<br />

the most resilient regions in the country when it comes to drought, the severity of the hot and dry weather<br />

experienced from May to August <strong>20</strong>18 (in particular), led to a rapid decline in our regional reservoir stocks. At times,<br />

the downward curve of reservoir levels mirrored that from the last significant drought experienced in the region, that<br />

of 1995/96. Despite the significant water resources challenge that the dry weather and at times high demands caused<br />

us, we did not hit formal triggers in our drought plan for either implementing Temporary Use Bans (TUBs) or<br />

requiring drought permits. This was, in part, reflective of the major investment that we made after the 1995/96<br />

drought, leading to the creation of our regional grid system which allows us to move significant quantities of water<br />

around our region. Although we did not hit our formal triggers, by early autumn – and after a very dry October – we<br />

made the decision to submit a number of applications for drought permits. These were intended to help our reservoir<br />

stocks recover over the winter period, by reducing reservoir compensation flows and allowing us to continue to<br />

abstract water from key rivers. This paper will explore lessons learned from the <strong>20</strong>18 drought in Yorkshire. In<br />

particular, we will look at issues that we will consider when updating our drought plan to enhance our resilience in<br />

the future. We will review the drought from beginning to end, considering how decisions were made at each stage,<br />

what influenced those decisions and how we worked with the Environment Agency during this challenging time. This<br />

will include looking at the information gathering process and use of common data sources – such as CEH’s online<br />

drought portal – to create evidence to support applications for drought permits. Further, the paper will explore<br />

issues around perception and communication in periods of drought. We will consider how our communications<br />

campaign evolved through the year and how we communicated with key external stakeholders and with our own<br />

colleagues.<br />

Amanda Fencl University of California, Davis presenting for Ruth<br />

Langridge University of California, Santa Cruz<br />

Groundwater management in planning for drought: experience from California, USA<br />

Groundwater is a critical water supply source during drought when it compensates for reduced surface water<br />

supplies. At the same time, there is less groundwater recharge. The result in California is that groundwater levels and<br />

storage have decreased over time and many groundwater basins are both degraded and depleted. Declines are<br />

primarily focused during droughts with recovery at other times. Climate change will exacerbate these declines with<br />

projections for higher temperatures and extreme droughts by the end of the 21st century. This will alter the natural<br />

recharge of groundwater including decreased inflow from runoff, increased evaporative losses, and warmer and<br />

shorter winter seasons. These changes will exacerbate already existing groundwater overdraft in many groundwater<br />

basins. Moreover, many areas in the state rely heavily on imported surface water from the Central Valley Project and<br />

State Water Project for groundwater recharge and consumptive use, and this water is projected to be less reliable<br />

and more expensive in the future.<br />
