					      Scientific Plan for LBA2
• Changing the principle…
• LBA1 – structure by disciplines
• LBA2 – structure by issues
  – Foster integrative science and avoid the
    dicotomy between social and natural sciences

  – Strategy of the working group – define some
    central issues and try to merge the former
    science questions and to build new questions
         Integrative Issues
1. Ecology of a changing environment
2. Sustainability of ecosystem services and
   aquatic and terrestrial production
   systems
3. Hydroclimate variability and change –
   adaptation and mitigation
1. Ecology of a changing environment

What are the impacts of managed and/or degraded forests and current
  agricultural configuration on the function of Amazon ecosystems?

What are the fluxes of energy carbon, trace gases and aerosols between the
  biosphere and the atmosphere over a wide range of ecosystems in Amazonia
  and what are the affects of human activities on those fluxes?
• sources and effects of particles and aerosols in the Amazon region?
• photochemical cycle of oxidants?

What is the impact of biomass burning emissions on the levels of air pollution and
  consequently the health of the human population of the Amazon region?
• trans-boundary pollution?
H.2 How do regional patterns define the transport of carbon and what do its
   transformations indicate about the relations between water movement,
   geomorphology and soils, and the structure of vegetation in the Amazon
   drainage basin?
H.3: What are the implications of land change and global climate change for these
   processes?
The Amazon estuary and forest-ocean interactions
The Andean periphery that includes focii of deforestation in Peru and Ecuador
   relevant to regional carbon balance
Flooded areas
Degraded lands
Ocean-atmosphere interactions.
Forest inventories and forest ages in varying landscapes
Water resources including restoration of surface water quality, use of ground-
   water, urbanization, and irrigated agriculture

•   Changing patterns of diversity?
2. Sustainability of ecosystem services, aquatic and terrestrial production
    systems

What are the impact of managed and/or degraded forests on the function of Amazon
    ecosystems?
Is the forest resilient under sustained management?
Is there a minimum area and configuration of remnant forests necessary to maintain the
    integrity of regional function?
What is the impact of the current agricultural configuration on the function of Amazonian
    landscapes and ecosystems?
What is the value of ecosystem services provided by Amazonian ecosystems?

M1: What are the fluxes of energy carbon, trace gases and aerosols between the
   biosphere and the atmosphere over a wide range of ecosystems in Amazonia and
   what are the affects of human activities on those fluxes?
What processes regulate the photochemical cycle of oxidants in the atmosphere of
   Amazonia and how are these cycles affected by human activity?
How will future changes in land use, land cover, and the rate of precipitation affect the
   hydrologic cycle and the fluxes of water, carbon, trace gases, and energy in
   Amazonia?
What is the impact of biomass burning emissions on the levels of air pollution and
   consequently the health of the human population of the Amazon region?
C1:What are the processes that control the stocks and fluxes of carbon, nutrients, trace
   gases, and water in the aquatic and terrestrial ecosystems of Amazonia in response
   to the following items: Land use and land cover; Climate; Air quality; Agricultural
   intensification and diversification; Forest management; Urbanization processes;
   Changes in landscape structure and species composition. It is important to
   emphasize that the regional budgets of carbon, nutrients, and trace gases are still
   inadequately quantified. At the regional scale, riparian zones are fundamental
   systems yet to be thoroughly investigated. A specific question may be posed for the
   riparian zones.
How do seasonally flooded and riparian environments modulate the distribution of
   oxygen, and nutrients affecting water chemistry, the emission of trace gases, and the
   cycling of carbon?
How do fluxes of matter and energy interact as a function of landscapes composed of
   multiple land uses and covers?

H1:How do land-water interaction processes scale to determine regional patterns?
How do regional patterns define the transport of carbon and what do its transformations
   indicate about the relations between water movement, geomorphology and soils, and
   the structure of vegetation in the Amazon drainage basin?
What are the implications of land change and global climate change for these
   processes?

L.3. Is there a minimum area and configuration of remnant forests
   necessary to maintain the integrity of regional function?

L.5. How does climate and land change affect the propagation of disease?

M.1. What are the fluxes of energy, carbon, trace gases and aerosols
  between the biosphere and the atmosphere over a wide range of
  ecosystems in Amazonia and what are the affects of human activities on
  those fluxes?

M.2. What are the sources of particles and aerosols in the Amazon region?

M.3. What are the effects of aerosols on cloud-microphysics, on the
   dynamics of convection, on precipitation, and on the fluxes of energy in
   Amazonia and how do these effects propagate to all scales of the global
   climate?

M.4. What processes regulate the photochemical cycle of oxidants in the
   atmosphere of Amazonia and how are these cycles affected by human
   activity?
M5. How might the climate of the Amazon region change in response to
  dynamic vegetation changes resulting from either land cover
  change or global climatic forcing? And, how will the Amazonian
  climate system including the vegetation dynamics and land use
  change feedback to the global climate?

M6. What is the relevance of regional and global teleconnections in the
  cycles of energy, water, and carbon in the Amazon region?

M7. How will future changes in land use, land cover, and the rate of
  precipitation affect the hydrologic cycle and the fluxes of water,
  carbon, trace gases, and energy in Amazonia?


M.9. What are the next exchanges of trace gases and aerosols between
   Amazonia and surrounding regions and how do these exchanges
   affect trans-boundary pollution?
C.1. What are the processes that control the stocks and fluxes of
   carbon, nutrients, trace gases, and water in the aquatic and
   terrestrial ecosystems of Amazonia in response to land use and
   land cover; Climate; Air quality; Agricultural intensification and
   diversification; Forest management; Urbanization processes;
   Changes in landscape structure and species composition.

    C.3. How do fluxes of matter and energy interact as a function of
       landscapes composed of multiple land uses and covers?

H.1. How do land-water interaction processes scale to determine
   regional patterns?

   what do its transformations indicate about the relations between

   change for these processes?
