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 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 3  A Global "Local Hazard model"  
Lead ICRAF-SEA
Collaborator UNH 
Status  Cannot be completed in Phase II; deferred to 2004 depending on additional funding.
Scope   Pantropic
Scale to be determined
Methods  

A. Deriving the rules for identifying local hazards. 
i. Specify which hazards are to be considered: flooding potential 

ii. UNH team will classify the range of values that define tropical watershed typology, such as landform, soils, geology, landcover, deciduosity and climate. These ranges will then be used to constrain an experiment on hypothetical tropical watersheds (virtual watersheds) performed by the ICRAF-Indonesia team (Meine & crew) using GenRiver. These experiments will define a set of “rules” which will then be mapped at the pan-tropical scale to determine the watershed sensitive to land-use change and an increase in local hazards. See Virtual_watershed.doc for details. 

B. Pantropic mapping of local hazards

See Relief and population.ppt [777Kb] (sent on 6/10/03) for example.
