What is a drought impact?“An observable loss or change that occurred at a specific place and time because of drought.”

NATIONAL DROUGHT MITIGATION CENTER

Why track drought impacts?

Research: How do biophysical indicators relate to social and environmental indicators?

Need longitudinal data.

Response & Recovery: Who really needs help?

Planning: What do we want to prevent?

Drought Planning: The Big Questions


What do you want to protect?

What can you do ahead of time? During

drought?

How will you know you are in drought?

Scale matters

Impacts &

Vulnerability:

• How have past

droughts affected

you?

• How would a

future drought

affect you?

• What do you need

to protect?

Monitoring:

• How dry is it?

What will you

measure?

• Who is

keeping

watch?

• Who needs to

know?



Impacts:• How has drought

affected you in the past?

• How is drought affecting you now?

• How would drought affect you in the future?

Vulnerability x hazard = impact

Drought intensity, duration

• Subsistence agriculture

• Shallow wells• Poor soil

What you can control: Reduce vulnerability ahead of time

x =

Impacts point to underlying vulnerability. “Solve for” vulnerability.

Drought Monitoring & Early Warning

Establish an operational definition or definitions of drought, based at least in part on the impacts that you want to prevent.• large-scale climate indicator• locally-relevant water supply indicator

WHO is monitoring drought regularly?

WHO needs to know when it gets worse?

How can the general public tune in to drought monitoring?

What can you do during drought?



drought?

Mitigation Actions• Adopt agricultural practices that enhance soil health• Manage for multiple priorities, not just one (i.e., don’t

prioritize agriculture and deprecate ecosystem services)• Purchase, position firefighting equipment• Enhance water supply and storage infrastructure• Revise laws/policies to align incentives with increased

drought resilience

Response Actions• Hay hotline• Haul water• Food distribution• Mental health hotlines• Water use restrictions


Stakeholder, public buy-in

Involve key stakeholder groups in impact assessment subcommittees

Keep the general public informed

Monitor drought at regular intervals, even when there is none

Develop messaging ahead of time to request behavioral changes

Involve people


Authority, political will

Who leads drought planning?

What authority do they have?

What is the scope or jurisdiction of the plan?

What is the overarching purpose or motivator of the plan?

Plans need to be formally adopted.

Make it official

Questions & ChallengesNo methodology for valuing or quantifying drought impacts

◦ Even in agriculture

No units

Easier to list than to summarize impacts

“Angst index”

Disincentives to sharing some info◦ Proprietary

◦ Competitive

On the up side …

Resource for drought historians

Impacts include attribution – we know drought caused it

Using media’s agenda-setting function to ID impacts that matter

Awareness – of what? Is there data re/ underlying trend?

Inventory of drought impact dataBY SECTOR

Agriculture

Tourism & Recreation

Ecosystems: plants & animals

Public health◦ Domestic wells

◦ Environmental health

BY TIME

Cumulative, end-of-season vs.

Real-time, “condition-monitoring”


Could always be better, but fairly well-represented. Some quantification possible, depending on USDA’s

National Agricultural Statistics Service data collection for particular crops and places.

• NASS data: Not all crops, and not always timely release, to protect proprietary information.

• Farm Service Agency reports: Valuable field-level reports at weekly time intervals, but sometimes

aggregated to large spatial area. Requires finding and reading each one individually. Not convenient.

• Risk Management Agency crop indemnity losses: Good source of annual losses to commodity crops due

to drought.

Agricultural Sector: Data exists, but is it enough?

Hydropower & Energy:Data exists. Do decision makers need something more or different?

Public water suppliesStates track differently.

Private domestic

wells.Most states

don’t track(?)

Public health other than domestic water

Connections in US not well-articulated. Anecdotal reports and a few studies on • Stress• Mortality• Hospital admissions due to air quality• Vector-borne disease

Tourism & RecreationData exists but it may be proprietary, and/or there may be a disincentive to sharing.

WASHINGTON STATE SKI VISITS (SOURCE: NATIONAL SKI AREAS ASSOCIATION)From them Washington State drought plan revision, vulnerability chapter

In the winter of 2004/2005, visitation to Washington State ski resorts dropped by 1.5 million visits from the prior year, a decrease of 77 percent. During the 2014/2015 winter, visitation numbers dropped by more than 900,000 visits from the previous year, a decrease of 59 percent.

Other suggestions:• Transient Room Taxes,

collected by the county • Pacific Northwest Skiers

Association (including some proprietary information)

• Travel Oregon

Environment / ecosystem services

• Perpetually under-resourced. • Endangered species well-tracked (?)• Otherwise, could use more data. • Where to start?

• Vegetation reports?

DIR or something similar could be used for monitoring native perennials and invasive annuals, especially cheatgrass and more recently, medusa head. “…someone would take a picture and note that this whole hillside is cheatgrass. Grass is relatively easy to identify, and we if have a georeference for that we could probably figure out which hillside is that and in the office we could create a polygon” (6).
