Impact Assessments

Measuring the socioeconomic benefits that Earth observations provide when people use them to make decisions

Overview

The VALUABLES Consortium is measuring the socioeconomic benefits that Earth observations provide when people use them to make specific decisions to manage water resources, health and air quality, climate change, wildfires, and more. To do this, we are conducting a series of impact assessments. These are rigorous, quantitative studies that investigate how people use improved information to make these decisions and quantify how these decisions improve socioeconomically-meaningful outcomes such as lives saved or resources conserved.

Popular in fields like international development, impact assessments quantify the changes that can be attributed to a particular intervention like a project, program, or policy. We are conducting impact assessments for specific satellite data applications using an approach called the value of information (VOI). The VOI method compares outcomes in two different states of the world: a state in which action is taken based on currently-available information and a different state in which action is taken using improved information. The difference in socioeconomically-meaningful outcomes between the two states represents the value of the information.

VALUABLES Impact Assessments

Our impact assessments include work that quantifies the value of using satellite data to:

  • Protect endangered species: The satellite data product WhaleWatch incorporates remote sensing to identify more precisely where blue whales are located in time and space, enabling their conservation at a lower cost. Read the full working paper.
  • Inform post-wildfire response: The US Forest Service Burned Area Emergency Response (BAER) team uses Landsat imagery to design cost-effective mitigation and recovery plans for the human and natural systems impacted by wildfire. Read the journal article.
  • Enforce air quality standards: Satellite data could be used to improve monitoring of county-level compliance with federal air quality standards and prioritize air pollution control activities that protect human health. Read the full working paper.
  • Regulate air emissions from oil and gas development: Monitoring air quality using satellites can improve our understanding of the relationship between emissions from oil and gas development and infant health outcomes.
  • Detect harmful algal blooms: Remote sensing can detect harmful algal blooms in recreational lakes and help managers take necessary steps to protect human health. Read the journal article, the Resources article, and the full working paper describing this work.
  • Improve predictability of corn and soybean prices: Satellite-based applications can reduce weather-related uncertainty that contributes to risk for agricultural commodity consumers and producers. Read the journal article.
  • Improve drought and river flow forecasts: Three-month soil moisture forecasts based on data from the GRACE satellites could be used to improve policy responses to drought and flooding.

VALUABLES Community Impact Assessments

The consortium is also supporting research from the VALUABLES community to quantify the benefits of using satellite data in decisions that improve socioeconomic outcomes for people and the environment.

This includes impact assessments on health, ecosystems, and water quality applications funded under VALUABLES' 2020 Grants for Assessing the Benefits of Satellites (GABS). Learn more about the GABS teams and their projects. These projects were led by researchers from Moravian College, Salisbury University, and the University of Wyoming.

Additional VALUABLES-supported impact assessments led by researchers from Arizona State University and the Georgia Institute of Technology measure the value of using satellite data to:

  • Halt disease transmission: Using satellite data to produce more accurate maps and population estimates can support vaccination campaigns and limit the spread of disease. Read the full working paper.
  • Support elk migration: Developing modeling approaches based on satellite data can provide information on how to design cost-effective migratory corridors. Read the full working paper.
