In this chapter from the virtual exhibition “Global Environments: A 360º Visual Journey,” Claire Lagier’s 360º video shows six-year-old agroforestry projects in a land reform settlement in the state of Paraná, Brazil. Her research focuses on agroecological rural social movements in this region.

The idea for this virtual exhibition came out of the joint Russian-Austrian research project “The Long-Term Dynamics of Fish Populations and Ecosystems of European Rivers.” Analyzing the history of fish populations in the Neva and Viennese Danube, the Russian-Austrian research group discovered numerous links between the great cities and their great rivers, including the fish populations. The project has been supported by the Rachel Carson Center for Environment and Society.

In this chapter of their virtual exhibition “‘Commanding, Sovereign Stream’: The Neva and the Viennese Danube in the History of Imperial Metropolitan Centers,” the authors discuss how the growing population required a lot of food and fish was significant part of the city dwellers’ diets. Social stratification led to the clear division between fish commodities for the wealthy and those for poor citizens, though some kinds of fish could be popular among all dwellers, regardless of social differences.
