Practice Areas

Environment

The preservation and protection of the environment, the effect of recreational activities on natural resources and habitats, and the public’s attitude towards climate change are all critical policy issues. Abt SRBI conducts large-scale, national and regional surveys that support the collection of high-quality quantitative data for use in policy evaluation, planning, and monitoring natural habitats.

Expertise
Surveys implemented by the group routinely feature:
  • Large studies that are national or regional in scope
  • Complex dual frame sample design
  • Data collection using ABS samples for household surveys
  • Mixed-mode data collection
  • Experimental design with complex sample management and data collection plans
  • Non-response bias studies, non-response analysis and weighting
EXAMPLES OF PROJECTS
Currently, we are supporting the National Marine Fisheries Service and the Environmental Protection Agency in conducting large scale, national and regional surveys with complex sample designs and mixed-mode data collection techniques. These projects support collection of high-quality quantitative data in issue areas such as recreational fishing, interaction with sea-turtles, and preserving the quality of aquatic habitats and resources for use in policy evaluation, planning, and monitoring the natural habitats.
 
Other projects include:
  • Dual Frame Mixed Mode Survey of Fishing Effort (NOAA), a large-scale and multi-wave survey that screens approximately 125,000 households and conducts in depth interviews among some 35,000 saltwater anglers. A dual-frame, mixed-mode study, data is collected by a self-administered mail and a telephone survey. 84 individual
  • Survey weights are created over the six waves that reflect the complex design of the study as well as the substantive and methodological research goals.  The weights developed for this study account for factors such as differential probabilities of selection across sampling strata, sample units with undetermined eligibility status, sampling frame overlap, screener survey nonresponse, and main survey nonresponse.
  • The TMDL Chesapeake Bay (EPA) study, a stated preference survey in three survey regions covering 18 states in the Northeast, Mid-Atlantic and Southeast. SRBI is providing sample design and data collection services for this study that employs a complex experimental design to collect data on respondents’ preferences on policy alternatives to reduce pollution in the Chesapeake Bay. The SRBI team was also critical in the OMB approval process of the project and developed key sections of the Information Collection Request (ICR) packet.
  • Angler Interaction with Sea Turtles (NOAA), conducted in North Carolina among recreational saltwater anglers to collect data on any encounter with sea-turtles while fishing. The study is conducted through a self-administered mail questionnaire and is conducted over multiple waves.
