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 2a. Enhace the capability of the WBM to represent (post-deforestation) agricultural land cover classes. 
                    Task 2b. Create the baseline or  'potential' land cover surface. 
                    Task 2c. Create the 'current' land cover surface. 
          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 A1iii. 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.

Description This task generates an assessments of land cover and land cover change over two distinct time periods: original (“potential”/pre-industrial) to “current”, and current to a range of stylized future conditions – primarily as a consequence of the conversion of forest to cultivated (and urban) systems. Sub-tasks involve generating separate land cover maps for each of the specificied “points” in time, as well as reconciling the land cover classes in pan-tropic land cover datasets with the land cover classes represented in the pan-tropic hydrological model, WBM. Reconciliation involved generating some new land cover options within WBM to accomodate agricultural (post conversion) land uses, as well as simplifying land cover classes used in available global datasets to match the range of “natural” land cover classes embedded in WBM.
