    During a seminar held at the Serviço Nacional de Aprendizagem Comercial (SENAC) in São Paulo, Brazil, Dr. Eric A. Davidson discussed some topics of his book You Can't Eat GNP: Economics as Though Ecology Mattered published in 2000.

    In this book, Dr. Davidson explains linkages between economics and ecology in examples ranging from the present legacy of a 19th century cotton farmer in North Carolina to the future impacts of a modern day rancher’s decisions in the Amazon Basin. The author states that the interdependence of ecology and economics is being reflected in language. He shows that economists and ecologists are now communicating across disciplines in a new field called "ecological economics". Excerpts of this publication can be seen on You Can't Eat GNP: Economics as Though Ecology Mattered

Science Questions:

Carbon Dynamics:

        CD-Q2 - How do biological processes such as mortality and recruitment or succession following land use change influence the net annual carbon balance for different land cover and land use types?
        CD-Q3a - How do pools and fluxes of carbon and nutrients (in soils) of pasture/cropland change over time and what factors determine carbon gain or loss?
        CD-Q3c - What factors (biologically mediated, land use history, soil properties, etc.) control the rate of carbon sequestration in biomass and soils of regrowing forest?

Nutrient Dynamics and Surface Water Chemistry:

        ND-Q1 - How do stocks, cycling rates and budgets of carbon and important elements nitrogen, phosphorus, potassium, calcium, magnesium, and aluminum change under different land covers and land uses?
        ND-Q2 - Are nutrients major factors that control the rates of regrowth and carbon accumulation in abandoned pastures and regrowing secondary forests?
        ND-Q4 - How do changes in land use and climate alter the stocks, processes and fluxes of dissolved and particulate organic matter, nutrients, and trace gases from the uplands across the riparian zones and floodplains and down the channels of river corridors?
        ND-Q4a - How will the composition and quantity of nutrients and organic matter entering and being processed within streams be altered under different land-use change scenarios?
        ND-Q4c - To what extent do intact riparian zones buffer streams against changes due to anthropogenic activities in surrounding uplands?
        ND-Q5 - What is the importance of periodically "wet" environments (from moist soils to standing and flowing waters) for the land and atmospheric balances of nutrients, carbon dioxide, trace gases, and water and energy on multiple scales?

Trace Gas and Aerosol Flux:

        TG-Q1 - How are fluxes of trace gases and aerosols between ecosystems (both upland and wetland) and the atmosphere of Amazônia affected by land cover and land use change?
        TG-Q2 - What is the (climatically driven) seasonal and inter-annual variability of trace gas and aerosol fluxes between the atmosphere and different land use and land cover types?
