Flood Planning and Climate Forecasts at the Local Level AgEcon
Wernstedt, Kris; Hersh, Robert.
We examine the use of El Nino-Southern Oscillation (ENSO) forecasts for flood planning in the Pacific Northwest. Using theories of resource mobilization as a conceptual foundation, the paper relies on: 1) case studies of three communities vulnerable to flooding that have had access to long-term forecasts of ENSO conditions; and 2) analysis of data collected from a survey of nearly 60 local emergency managers, planners, and public works staff. We find that understanding the regulatory machinery and other institutions involved in using climate forecasts is critical to more effective use of these forecasts. Forecast use could be promoted by: 1) an extension service to broker climate information; 2) the identification or creation of federal authorities to fund...

NATURAL HAZARDS AND RISK AVERSION: EXPERIMENTAL EVIDENCE FROM LATIN AMERICA AgEcon
van den Berg, Marrit; Fort, Ricardo; Burger, Kees.
We use experimental and survey data from two natural-hazard prone countries in Latin America to test the hypothesis that natural hazards affect risk aversion. We use two methods to measure risk aversion: simple questions on the willingness to pay for a hypothetical lottery and more complicated experiments involving real pay-offs. We find that whereas the experiments provide reasonable estimates of risk aversion, the hypothetical questions result in unrealistic distributions of preferences. The experimental results strongly support the hypothesis that experiencing natural shocks makes people more risk averse, not only in the short run but also in the medium and long run.

The Esmeraldas Canyon: a helpful marker of the Pliocene‐Pleistocene tectonic deformation of the north Ecuador southwest Colombia convergent margin ArchiMer
Collot, Jean-yves; Ratzov, Gueorgui; Silva, P.; Proust, J.‐n.; Migeon, Sebastien; Hernandez, M.‐j.; Michaud, F.; Pazmino, A.; Barba Castillo, D.; Alvarado, A.; Khumara, S..
Deciphering the migration pattern of the Esmeraldas submarine Canyon (EC) and its history of cut‐and‐fill allows constraining the Pliocene‐Pleistocene tectonic evolution of the Ecuador‐Colombia convergent margin. Swath bathymetry, multichannel seismic reflection and chronological data show that the EC is a 143‐km–long, shelf‐incising, river‐connected canyon that started incising slope apron deposits in the Manglares fore‐arc basin ~ 5.3 Ma ago. The EC inception appears contemporaneous with the subduction of the Carnegie Ridge that is believed to have initiated 5‐6 Myr ago and is considered an indirect cause of the EC formation. During its two‐stage left‐lateral migration, the EC upper‐half scoured deep incisions providing evidences for uplift episodes in...
