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

iv Undertake synoptic modeling of hydrological impacts of land use change

           Task 1 Prepare daily precipitation data and hydrological model representation as a basis for assessing the incidence and severity   of flooding at the pantropic scale in the WBM

                   Task 1a. Check availability and accessibility of all model input data (e.g. precipitation, humidity, etc) in common spatial and temporal resolutions

                   Task 1b. Revise WBM for application at daily time step

        Task 2  Synoptic modeling and analysis

        Task 3  A Global "Local Hazard model"  

        Task 4  Pantropical mapping and overlays

Activity 1B Pantropic assessment of the potential threat posed by hydrological disturbance and impact
Sub-activity

 1Aiv. Task 1b: Revise WBM for application at daily time step  
Lead  UNH
Status  In progress
Scope   Regional to Pan-tropic (depending on data source)
Scale (Resolution) 0.5dd (30 arc minutes)
Methods   Daily WBM analysis within model domain appropriate for local vulnerability analysis.  This may entail monthly analysis for entire pan-tropics and then daily analysis for selected areas. 
Inputs  Results of sub-task 2a and zero-order local hazards analysis.
Output
  • Daily runoff generation resulting from "potential" and "current" land cover.
  • Statistical analysis to compare shift in hydrologic behavior due to change in land cover
  • Evaluate changes in local hazards due to results of statistical analysis
Linkages to policy-briefs and other deliverables Synoptic modeling; hydrologic vulnerability analysis
Milestones 
  • Evaluation of daily data sources and accesibility
  • Interpolation of daily rainfall gridded surface 
Date Expected Assessment of feasibility expected 8 October 2003.

General notes, 

Comments 

 Engineering effects will only be studied where info is available at the specific point, no engineering effects will be studied on watershed functions. Effects of engineering/human alterations will be inferred from composite runoff field developed by UNH, which combine modeled and observed RO. However, composite runoff available at monthly time step.
