As part of the project IFOP “Logistical support for the development and management of action plans and regional programs of conservation of aquatic species and adaptation to climate change in fisheries and aquaculture” in Valparaiso a group of experts discussed about the climate change. In addition this activity was supported by the Subsecretaría de Pesca.

IMG_3092In this activity exposed Dr. Samuel Hormazábal, Director of the Escuela de Ciencias del Mar de la Universidad Católica; Dr. Leonardo Guzman head of the División de Investigación en Acuicultura of IFOP; Dr. Rodolfo Sapiains, of the Centro de Ciencia del Clima y la Resiliencia de la Universidad de Chile; Dr. Cristian Vargas, of the Facultad de Ciencias Ambientales de la Universidad de Concepción and Director of the Millennium Nucleus MUSELS; Dr. Silvio Pantoja, Director del Programa COPAS Sur Austral: Dr. Carlos Molinet of the Instituto de Acuicultura of the Universidad Austral de Chile; and Elizabeth Palta, head of the economy section of the IFOP.

Leonardo Nuñez, Director of IFOP, said that “the institution has initiated a process of internal restructuring and in order to strengthen the oceanography, a specific department was generated in the Division of Investigación Pesquera, whose aim is to generate the necessary information that allow us to understand more accurately the real effects of climate change on the ocean and our marine resources.”

Dr. Samuel Hormazábal, presented an overview of how the system of the eastern edge of Chile-Peru in physical and dynamic terms works, and the impact that has on the ecosystem and the climate variability associated with El Niño in the southern area.

In relation to the climate change, Dr. Silvio Pantoja, adds that “the system is extremely complex. In addition to the variations generated by the rising of the ocean temperatures and the planet in general, there is changes that this overlapping to these variations like El Niño, that is immersed in the environment; if we also consider that half of the world’s population is linked to the ocean, either by living near or by activities associated with the coast as shipping and tourism, that promotes other problems that affect to the ocean, such as waste (product of the human activity), sewage and others that impact the environment. What we have to decide as a society, is how far we can go with this to have a healthy environment. “

He also says that “climate change is related to the effects on the change of the ocean regime. There are places where spawning areas have cooled, which has declined the recruitment of species.”

c-vargas-foto-web-1Dr. Cristian Vargas, Facultad of Ciencias Ambientales de la Universidad de Concepción and Director of the Millennium Nucleus MUSELS, specialist in studies of ocean acidification and other stressors in marine environments, with his talk “Sustainable Aquaculture at a time of global change: the generation of adaptive capacities to cope with environmental and socio-economic forcings” he presented results regarding different studies along the Chilean coast, by the scientific community, whose focus has been to evaluate the biological responses of different marine organisms (eg phytoplankton, zooplankton and shellfish), some of them of economic importance for the aquaculture of benthic resources (eg mussels and oysters).

“The research team of MUSELS has been pioneered in the experimental work to assess the responses of these species in aquaculture faced to stressors associated with global change, as well as in the study of its implications for the socio-ecological system of shellfish aquaculture,” says the Dr. Vargas.

While Dr. Leonardo Guzman (IFOP) focused his presentation about the guidelines to develop with the community to face the occurrence of red tide or changes of long term such as climate change. The idea is that the persons have a better understanding regarding the actions to be taken by the authorities to minimize impacts.

The specialist also addressed the activities to be undertaken at the individual level and at the level of organized society to produce certain changes in people. “It is important that they know and understand the environment in which live and how they can respond responsibly when the authorities take measures to protect the public health (for example in the case of harmful algae) and also to minimize the impacts on productive activities, “he says.
