Sistemas agrarios sustentables y transiciones en el metabolismo agrario: desigualdad social, cambios institucionales y transformaciones del paisaje en Catalunya (1850-2010)

How did farmers maintain soil fertility as they cultivated the same land over decades and centuries? How did they transfer energy and nutrients (nitrogen, potassium, phosphorous) across the landscape to fertilize crops? How did farmers structure landscapes (field, pasture, woodland) to sustain communities, ensure long-term productivity, and produce profits? We summarize in this article the results of the ongoing research on the last stage of organic agriculture in Catalonia carried out by our project. We also outline the forthcoming steps to continue our research.

História ambiental: um olhar prospectivo

Examination of methodological approaches and work possibilities for historians in the research and teaching of history of environment, its themes and potential objects of studies. The attention to books and articles helps on this balance and on the identification of future routes for the Environmental History in Brazil. This historiographical practice has been keeping, among us, a salutary opening for the dialogue with the foreign historiography, with an increasing valorization of the research in Latin America and with social science and natural subjects. The incipient Foreign Exchange Program suggests the tasks and the success found by this approach will be result of the interaction between researchers, projects in group, circulation of publications and institution strengthening of the historical knowledge in the beginning of the century.
