1 Workshop, Pretoria – South Africa
Land Use System Versión 2.0 LADA Argentina Team “LUS map” Workshop, Pretoria – South Africa 16 – 18 September 2008

2 Objetive Define the Land Use System like a tool for the assessment and monitoring of desertification and land degradation.

3 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

4 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.

5 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.

6 Methodology Steps for the LUS construction + Attributes associated LUS

7 Methodology Steps for the LUS construction
Reclassification of GLC 2000 and change in the resolution

8 Methodology Steps for the LUS construction

9 Methodology Steps for the LUS construction

10 Methodology Steps for the LUS construction

11 Methodology Steps for the LUS construction
Reclassification from irrigation 2007 map and change in the resolution

12 Methodology Steps for the LUS construction
Generation of the urban and protected areas map

13 Methodology Steps for the LUS construction
Obtain from the intensity livestock map.

14 Methodology Steps for the LUS construction

15 Methodology Steps for the LUS construction

16 Methodology Put all the maps together Reclassification
Steps for the LUS construction Put all the maps together Reclassification Rename the categories results

18 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.

19 Strategies for the LUS validation
Direct evaluation for the LUS. Attributes revision. Critics point identificated during the construction.

20 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.

30 Irrigation From a global database:
Global map of irrigated areas (version 4.0.1, February 2007). Center for Environmental Systems Research, University of Kassel And Land and Water Development Division (FAO) Resolution original: 3 arc min. Processed, reclassification and re-scaled
