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
iii Measure historic change in land cover and develop scenarios for areas of rapid change in land cover
         Task 1  Identify basins that generate runoff in the pan-tropic focus area 
            Task 2   Derive land cover surfaces for different points in time as a basis for assessing the historic and potential impacts of land use change in tropical forest biomes   
          Task 3  Develop scenarios for projecting from current to a range of stylized future land use/cover conditions.

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

1Aiii. Task 1:  Identify basins that generate runoff in the pan-tropic focus area 
Lead UNH
Collaborator IFPRI
Status  Completed (version 1 based only on biome 1 completed 2/03; final version based on biomes 1-3 completed 4/03)
Scope   Pan-tropic
Scale (Resolution) 0.5 dd (30 arc minutes)
Methods  

  • Overlay basins derived from the 30-min Simulated Topologic Network (STN-30) with the pantropic extent as defined in Activity 1.A.i Task 1

  • Isolate all basins that overlap with any portion of the pantropic biomes 1,2 & 3.
Inputs  WWF Ecoregions/Biomes; Basin boundaries
Outputs

  • Basin extent boundaries (i.e. mask of basin area)

  • Pantropic study area basin surface with individual basin boundaries
Linkages to policy-briefs and other deliverables Provides window of analysis for all components of the pan-tropic study.
Milestones  Basin boundaries agreed, Analysis extent defined.
Date Expected April 2003

General notes, 

Comments 

 The hydrological analysis will be performed and results summarized separately for each biome.
