BNPP/ASB Functional Value of Biodiversity Project – Phase II 

2. Implementation Plan for Activity 1
Activity 1A Improved spatial characterization of the focus area at the pantropic scale 

i Assemble more detailed information on biodiversity-rich tropical habitats (IFPRI lead initiative)
ii Integrate improved data on human population distribution
             Task 1: Perform overlay analysis of ecoregions within the pantropics and population data
             Task 2: Identify biodiversity 'hot-spots' 
iii Measure historic change in land cover and develop scenarios for areas of rapid change in land cover

iv Undertake synoptic modeling of hydrological impacts of land use change
Activity 1B Pantropic assessment of the potential threat posed by hydrological disturbance and impact
Sub-activity

1Aii. Task 1: Perform overlay analysis of ecoregions within the pantropics and population datasets 
Lead IFPRI
Collaborator UNH
Status  Delayed due to lack of updated population datasets (CIESIN GPW v3.0 & Rural/Urban population datasets are currently available for Africa - the global product is due for completion in August/ Sept). In the event of further delays the analysis can be doneusing GPW v2.0 and/or LandScan 2001.
Scope   Pan-tropic
Scale (Resolution) 5x5 km
Methods   Data overlay to determine number of people in focus area; average density, urban/rural composition and the location of human settlements within ecoregions
Inputs 
  • GPW v2.0 (CIESIN, 2000)
  • GPW v3.0 (CIESIN, 2003)
  • Human settlements (CIESIN, 2003)
  • LandScan Population (ORNL 2001)
  • Citylights (ORNL)
Output
  • Comparative analysis for Africa of the 4 currently available population datasets
  • Statistical analysis of population characteristics for each ecoregion
  • Location and size of urban populations for each ecoregion
  • Location and density of rural populations for each ecoregion
  • Outputs will directly feed into the discussion papers/policy briefs
Linkages to policy-briefs and other deliverables
  • input to hydrological vulnerability analysis (e.g. assessing the threat of local and farfield effects on human populations)
  • input to identification of biodiversity hotspots (e.g. potential population pressure on forest (biodiversity) resources)
  • provides underlying analysis for paper #1
Milestones  Comparative analysis for Africa to determine value of waiting until the new/revised datasets are released to complete analysis.
Date Expected Preliminary analysis can be done with GPW v2.0 and/or LandScan 2001 by July; final analysis cannot be done until release of human settlements database and GPW v3.0 (see notes for expected release dates)

General notes, 

Comments 

 GPW v3.0 - Africa currently available; global expected in August; Human Settlements database - Africa currently available; global expected in September 2003.
