Resumen:
Whale watching targeting southern right whales began in Península Valdés, Argentina, in 1973. Building a long-term collaboration with stakeholders, including managers, has allowed the sustainable development of whale watching in this location. This holistic approach focused on setting Limits of AcceptableChange by assessing indicators in four dimensions: Social, Political, Economic and Biological. Social indicators include the percentage of acceptance of whale watching by local inhabitants; attitude changes in people on conservation issues affecting whales; and the importance of the whales in daily life. Political indicators include regulations and governance. Economic indicators include theinclusion in the provincial budget of whale watching ?credits? and incentives to whale watching operators. Biological indicators include whale respiration rates(observed from land via theodolite) in the presence and absence of whale watching vessels and an evaluation of the proportion of whales being affected by the activity. Respiration rate data indicate that the presence of whale watching vessels is the only variable influencing changes; collecting these data is a first step toward building bioenergetic models to assess the mid- to long-term impacts of whale watching. All of these indicators will be incorporated into a Bayesian Decision framework.
