Mini-project 2 Background Information

Guidelines for Research Component 2
Questions oriented to the interests of individual participants

A) Biomass and carbon content of Acre’s forests (Angelica Almeyda and Carla Morsello)

  1. What is the uncertainty in primary forest biomass in Acre, using the 10 ha plot near Rio Branco as a source of data. What is the importance of the allometric equation used in this uncertainty?
  2. What is the time necessary for biomass accumulation in secondary forests to approximate primary forest, using linear extrapolation and negative exponential extrapolation?
  3. What are the implications of the above information for public policy in Acre?

B) Comparative regional estimates of burning using GOES data (Andrea Chavez)

  1. What is the relative amount of burning, estimated using GOES hot pixel data, along the highway BR-317 from Rio Branco to Assis Brasil and from Assis Brasil to Puerto Maldonado during 1998?
  2. Are there significant differences as to when and the duration of burning in Acre and Madre de Dios?
  3. What are the implications of this information for public policy in these regions?

C) Occupation of frontier region Bolivia-Acre (Jane Read and Ignacio Llovet)

  1. Is the estimate of 6,000 to 15,000 Brazilian rubber tappers in the Bolivian border region reasonable?
  2. What is the size distribution of the clearings and what is the implication of this distribution as to the capital accumulation of rubber tappers?
  3. What are the implications of this information for international public policy in this region?

D) Analysis of the Large-Scale Biosphere Atmosphere Experiment in Amazonia (LBA) abstracts of June 2000 (Daniel Lopez Giraldo)

  1. Land cover/land use change (LCLUC) is a primary driver for change in the Amazon Basin. What extent is LCLUC as a driver being studied within the LBA program? What are the gaps in this subject?
  2. What are the implications of these results for the next research announcements for LBA?

E) Estimates of forested area in the Seringal Porongaba (Andre Mendes and Juan Pablo Guerschman)

  1. How may one divide the forested area of the Seringal among the residents? How much has each family unit deforested?
  2. What is the uncertainty in such division?
  3. What are the implications of these results for management of extractive reserves?

F) Estimates of rates of deforestation, using Porongaba Seringal as an example, and analyzing the differences among deforestation estimates for Acre (Glynis Ford and Jeff Bury)

  1. What is the difference in deforested area for 1996 and 1999? What is the apparent deforestation rate? What is the implication of this deforestation rate for policies linked to extractive reserves?
  2. What is the difference between the IBAMA and FUNTAC data at a municipal level? What hypotheses does this difference refute?
  3. What is the correlation between burning in 1998 and area deforested in 1996? Does this relation favor either IBAMA or FUNTAC deforestation data?
  4. Do the GOES data underestimate or overestimate burning? Use specific sites as examples.
