I am an Agricultural Engineer and Doctor in Environmental Sciences, current Professor in charge of the Aquaculture and Aquatic Ecology Lab of the Agronomy Faculty, Buenos Aires University, Argentina, with teaching in the courses of Limnology, Restoration and Fisheries. My main concerns are water bodies in agricultural and urban environments, the services they provide and the impacts they receive. My point of view is at the ecosystem level, and my favourite approach is through mesocosm experiments.
