Brasilia 2012

Aims & Requirements o Support land use planning & sediment management o Enable non-experts to participate

Non-complex system Easy to handle and to access

General

o Web based

o Meso-scale

o Focused on assessing effects of land use (change)

Step 1 Land use in grid system changeable by user

Step 2 assess effects of land use on landscape functions (LPF) Sediment retention C factor (USLE) Runoff control CN value (SCS) Nitrogen fertilizer amount of applied N fertilizer (FAO) Agronomic value statistics, agricultural goods (IGBE)

Step 3 include landscape properties & potentials (LPP) Potential for sediment input in river network Potential for water retention by soils Potential for Nitrogen loss control Soil productivity & suitability

Brasilia 2012

• Letsmap do Brasil is an integrating land use planning support tool, focusing on minimizing sediment input in river networks

• Other landscape functions are integrated, e.g. N retention, agronomic value (more are possible)

• Letsmap do Brasil is

o open to modification

o transparent & easy to handle

o participation is easy

• Letsmap do Brasil Is spatially explicit zoning

• Letsmap do Brasil is an integrating approach that might help to bridge the gap between “real” models and landscape planning
