Paris Agreement hampered by inconsistent pledges, new ICTA-UAB research finds

Some countries' Paris Climate Agreement pledges may not be as ambitious as they appear, according a new study carried out by researchers from the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB).

High lead concentrations found in Amazonian wildlife

Researchers from ICTA-UAB and the UVic-UCC detect high levels of lead concentration in wildlife samples from the Peruvian Amazon caused by lead-based ammunition and oil-related pollution in extraction areas.

Study gauges trees’ potential to slow global warming in the future

The Pyrenean forests, the Cantabrian coast and Galicia show an important potential to accumulate even larger amounts of carbon dioxide in the future and thus help to slow down the increase in CO2 concentrations which are warming the planet.

Why do environmentalists eat meat?

A study by researchers at the ICTA-UAB analyses the reasons why environmentally-minded scientists find it difficult to give up meat consumption, one of the world's greatest environmental problems.

La gestión del verde urbano permite incrementar la presencia de pájaros en las ciudades

Incrementar la biodiversidad del verde urbano permitiría aumentar la presencia de aves paseriformes en las ciudades mediterráneas, según un estudio científico realizado por investigadores del Instituto de Ciencia y Tecnología Ambientales de la Universidad Autónoma de Barcelona (ICTA-UAB) que analiza qué estrategias hay que implementar sobre la vegetación urbana para conseguir "naturalizar" las ciudades favoreciendo la entrada de flora y fauna.

The Ebro River annually dumps 2.2 billion microplastics into the sea

An ICTA-UAB study analyses the distribution and accumulation of microplastics from one of the main rivers of the western Mediterranean.

European project to support rooftop greenhouses projects

The Institute of Environmental Science and Technology from the Universitat Autònoma de Barcelona (ICTA-UAB) is launching an open call to support rooftop greenhouse projects, in the framework of GROOF Project.

New study dismisses green growth policies as a route out of ecological emergency

Researchers from ICTA-UAB and the Goldsmiths University of London suggest that emissions reduction is only compatible with a lower economical degrowth or a degrowth scenario.

Indigenous knowledge, key to a successful ecosystem restoration

Ecological restoration projects actively involving indigenous peoples and local communities are more successful. This is the result of a study carried out by the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB).

I obtained my PhD in Geosciences at the University of Marseille, France, in 2008 on the impacts of the El Niño Southern Oscillation on the distribution of marine calcareous phytoplankton along the north American Pacific margin over the last 30.000 years.  In 2009, I started a postdoc in the group of P. Ziveri at the ICTA. Specialized in paleoceanography and paleoclimatology, my research deals now with the impact of human-induced climate change on the coccolithophores, a key planktonic group of marine calcifiers at the base of the food web. The area of study is the Mediterranean Sea and I focus on the last 250 years. This period, starting with the Industrial Revolution, is characterized by an increased release of greenhouse gases to the atmosphere in relation to anthropogenic activities.  I am in charge of SYRACO, an automatic system of coccoliths recognition, which measures the size and mass of individual coccolith (the inorganic fossil remains of coccolithophores). Along with the distribution of the different species of coccolithophores,  the estimation of their morphometric parameters over the last 250 years make it possible to infer the impact of both ocean acidification and warming  on this key marine group.  In the frame of the European MedSeA project (Mediterranean Sea Acidification in a changing climate) in addition to my research, I was data manager, collecting and archiving the data produced during the project. I am now expanding my work to another anthropogenic stressor threatening the Mediterranean Sea: the accumulation of micro-plastics in the marine environment from the water column to the sediments.
