Workshop, Pretoria – South Africa Land Use System Versión 2.0 LADA Argentina Team “LUS map” Workshop, Pretoria – South Africa 16 – 18 September 2008
Objetive Define the Land Use System like a tool for the assessment and monitoring of desertification and land degradation.
Framework Identification the possible situations that could be associate to different levels of risk of desertification. Monitoring the changes that could be indicate an increase en the erosive activities
Methodology Upload and established by LADA during the life project Generals consideration Upload and established by LADA during the life project The final methodology it is not define yet. Its objective is complement the GLADA development.
Methodology Based originally in maps and global data bases. Generals considerations Based originally in maps and global data bases. Could be upload with local data respect the methodology propose. Resolution: 5 arc min. Average surface for pixel: 7200 ha.

LUS Regional Validation LADA needs to evaluate a validate the LUS to know its state. We should generate an strategy for the evaluation for the LUS and his attributes.
Strategies for the LUS validation Direct evaluation for the LUS. Attributes revision. Critics point identificated during the construction.
LUS Critical Points Resolution: each pixel represent the “dominant” system within the 7200 ha. Date for de data base: it is asynchrony multi-temporal since 2000 to 2007. Veracity from the individual components: quality from data and distribution. Construction methodology: limits from the classes.
