    Seabird bycatch in Chile: a synthesis of its impacts, and a review of strategies to contribute to the reduction of a global phenomen. (2015)

    Description: Chile holds globally important colonies of endangered and endemic seabird species, and globally vulnerable nonbreeding species visit its waters. One of the major threats for seabirds in Chilean waters is the impact of fishing activities, both industrial and artisanal, which overlap with seabird breeding and foraging areas. Bycatch in fisheries threatens 27 identified species and two groups of unidentified albatrosses and penguins, with the Black-browed Albatross Thalassarche melanophrys as the species most related to bycatch events. Responding to the international call for the voluntary adoption of a plan to reduce the impacts of fisheries on seabirds, Chile generated a National Plan of Action (PAN-AM/Chile) to monitor seabird bycatch, and to mitigate threats to seabirds with emphasis on industrial longline fisheries. Following the successful reduction of seabird bycatch in the demersal longline fishery for Patagonian toothfish Dissostichus eleginoides , with zero individuals caught during 2006, Chile is extending the PAN-AM/Chile to include other fisheries that use gear known to cause incidental mortality, such as trawl, purse seine, and gillnets. This initiative is supported by actions associated with the creation of a national scientific committee for biodiversity, and new collaborative research platforms under the auspices of the Chilean Undersecretariat for Fisheries and Aquaculture
    Description: Chile cuenta con importantes colonias a nivel global de especies de aves marinas endémicas y en peligro, así como especies no reproductivas globalmente vulnerables que visitan sus aguas. Una de las mayores amenazas para las aves marinas en aguas chilenas es el impacto de las actividades pesqueras, tanto industriales y artesanales, las cuales se sobreponen con áreas de reproducción y alimentación de aves marinas. Estas amenazan 27 especies identificadas y dos grupos de albatross y pingüinos no identificados, con el Albatros de ceja negra Thalassarche melanophrys como la especie más relacionada a eventos de captura incidental. Respondiendo al llamado internacional para la adopción voluntaria de un plan para reducir los impactos de las pesquerías en aves marinas, Chile generó un Plan de Acción Nacional (PAN-AM/Chile) para monitorear la captura incidental de aves marinas y mitigar amenazas con énfasis en pesquerías industriales de palangre. Seguido a la exitosa reducción de la captura incidental en la pesquería demersal de palangre para Bacalao de profundidad Dissostichus eleginoides, con cero individuos capturados durante 2006, Chile está ampliando el PAN-AM/Chile para incluir otras pesquerías que usan artes de pesca con conocida mortalidad incidental, tales como arrastre, cerco y redes agalleras.

    Using forecasting methods to incorporate social, economic, and political considerations into marine protected area planning (2021)

    Description: As the global environmental crisis grows in scale and complexity, conservation professionals and policymakers are increasingly called upon to make decisions despite high levels of uncertainty, limited resources, and insufficient data. Global efforts to protect biodiversity in areas beyond national jurisdiction require substantial international cooperation and negotiation, both of which are characterized by unpredictability and high levels of uncertainty. Here we build on recent studies to adapt forecasting techniques from the fields of hazard prediction, risk assessment, and intelligence analysis to forecast the likelihood of marine protected area (MPA) designation in the Southern Ocean. We used two questionnaires, feedback, and a discussion round in a Delphi-style format expert elicitation to obtain forecasts, and collected data on specific biophysical, socioeconomic, geopolitical, and scientific factors to assess how they shape and influence these forecasts. We found that areas further north along the Western Antarctic Peninsula were considered to be less likely to be designated than areas further south, and that geopolitical factors, such as global politics or events, and socioeconomic factors, such as the presence of fisheries, were the key determinants of whether an area was predicted to be more or less likely to be designated as an MPA. Forecasting techniques can be used to inform protected area design, negotiation, and implementation in highly politicized situations where data is lacking by aiding with spatial prioritization, targeting scarce resources, and predicting the success of various spatial arrangements, interventions, or courses of action.
