Activity Description

2003  

  • "Building a Portable Classroom: Teaching in the Amazon"

    In order to teach and overcome basic infrastructure problems for teaching and training in the Amazonian settings, this team developed a "portable classroom" system which is composed of 13 notebooks, a multimedia projector and other teaching devices that can be easily carried.

    The system has been used to teach the 40-hour course "Dynamics of the Environmental Systems" which focuses on the fundamentals of modeling on environmental systems using simple modeling tools.

    The course is organized in 6 modules:

    1. Introduction
    2. System Dynamics
    3. Biological System
    4. Carbon Cycle
    5. Climate System
    6. Hydrological System

    It also addresses major global environmental transitions and the equations that best represent the dynamic of the selected systems.

2004  

  • "The Atlas of the Biosphere"

    The Atlas of the Biosphere is an innovative online resource where students, educators, business leaders, and invironmental organizations can access and download state-of-the-art scientific data, images, and maps pertaining to human activities and the global environment.

    A new Atlas of Amazonia website (in Portuguese, Spanish and English), highlighting environmental information, is under development by this team.

Science Questions:

Carbon Dynamics:

        CD-Q1 - What is the (climatically driven) seasonal and interannual variability of the carbon dioxide flux between the atmosphere and different land cover/use types?
        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-Q3 - What are the relative contributions of fluxes from natural and disturbed ecosystems to the net Amazônia-wide flux?

Land Cover and Land Use Change:

        LC-Q1 - What are the rates and mechanisms of forest conversion to agricultural land uses, and what is the relative importance of these land uses?
        LC-Q2 - At what rate are converted lands abandoned to secondary forests; what is the fate of these converted lands, and what are the overall dynamic patterns of land conversion and abandonment?

Nutrient Dynamics and Surface Water Chemistry:

        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-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?
