Two Use Cases

Case 1: Agriculture and Water Quality Case 2: Earthquake Hazards

Case 1: Agricultural produc.on and nutrient loading

EO provides the popula.on of land uses, while tradi.onal techniques focus on only a sample of land uses or a lower quality

• f informa.on

EO facilitates spa.otemporal analysis of the impact of nitrates on groundwater resources when couple with dynamic 3-D ground water models

Completed for 350 wells in study area

Well capture zones and land use

Corn (114.2 lb/acre of N) & soybean (3 lb/acre of N) are largest crops

provided corn & soybean produc.on es.mates for 2001 – 2010

Over a 10-year period of analysis some groundwater wells are threatened by nitrate (NO3 -) contamination and could fail to maintain drinking-water quality in the next 10 years based on a three dimensional ground water model Price x quantity of the crop that would have been planted had we not considered the water quality can be used as a

• baseline. Price of corn is much higher and may be
• preferred. Goal is to maximize the amount of corn without

losing the water quality

Case 1: Summary

A produc.on possibility curve for a technological innova.on in geospa.al data (source: Forney et al 2012)

An economic model of produc.on efficiency

Produc.on efficiency and the produc.on possibility fron.er (PPF). The PPF represents produc.on tradeoffs of an economy given fixed resources. Movement from PPF0 to PPF1 is an increase in produc.vity. Movement along a PPF is a tradeoff between goods. Outcome: Estimated VOI for MRLI is an annualized $858M ± $197M / yr (in $2010) for northeastern Iowa

Southern CA scenario region Regional distribu.on of mul.family building damage es.mated at $2.9B Distribu.on of mul.family building damage and poverty by census tract in LA County; 42.2% of county popula.on in mul.-unit structures in 2000

Map of the USGS ShakeOut scenario in southern CA and mul.family building damage (Jones et al 2008) and census tracts with high levels of poverty in LA County (source: Bernknopf and Amos 2014)

Case 2: Pa\ern of expected damage to mul.family buildings in a M=7.8 earthquake scenario in southern CA (adding Social data)

Sta.s.cal indicator of earthquake risk concentra.on of building damage ranked by median household income

(source: Bernknopf and Amos 2014)

LA County results:

• Expected net benefit of voluntary mi0ga0on $1.1B ($0.4B) if mi0ga0on costs are 10% (50%) of

exposed real estate value

• 2,054 (2.6%) census tracts in LA County meet the income criterion for public investment (> 9% of

the popula0on below the poverty line) and would receive public investment in mi0ga0on

B/C and VOI mechanics

where Btω(i) is the benefit at period t with informa0on ω(i), Ct is the cost for period t, r is discount rate, VOIω(1) is the value of the new informa0on rela0ve to exis0ng informa0on , Bω(1) is the net economic benefit of the new informa0on, and Bω(0) is the net economic benefit with the exis0ng informa0on

Challenges encountered when analyzing impacts (from OECD)

• No direct link between investment and impact
• No single framework for assessment
• Lack of iden.fica.on of users
• Lack of appropriate indicators
• Complex transfer mechanisms (between

government, businesses, academia)

• Na.onal vs interna.onal programs
• Subjec.vity of non-economic impacts valua.on
• Time lag (it takes .me to impact society)
• Accoun.ng for changes in data policies

Challenges for Broad Applica.ons

• Geospa.al data is an Intermediate good
• Geospa.al informa.on value is determined on its

impact on final goods

– The demand for geospa.al informa.on is to reduce decision uncertainty – The economic value is an increase in produc.on efficiency

• Determining the value requires an understanding
• f its use in producing the final good - crea.ng

challenges to the crea.on of a broadly applied template for VOI
