Aims

General: Securing water supply for the region (Brasília DF)⇒ silting of reservoirs

Specific:• sediment sources and pathways

• minimize sediment input into reservoirs

o reduce sediment generation

o increase sediment retention⇒ Land use

Conclusions• Letsmap do Brasil is an integrating land use planning supportLetsmap 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, p g , g ,agronomic value (more are possible)

• Letsmap do Brasil is

o open to modification

o transparent & easy to handlep y

o participation is easy

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