Main points
1. Land degradation is a global environment and development issue.
2. Land degradation and improvement is inferred from long-term trends of productivity when
other factors that may be responsible climate, soil, terrain and land use) are accounted for.
3. In Argentina, net primary productivity increased over all during the period of 1981-2003.
4. 37 per cent of the population (14.5million out of 39. 1million in 2005) live in the degrading areas.
5. There is some correlation between land degradation and aridity: 69 per cent of the degrading areas are in the humid regions, 13 per cent in the more restricted dry sub-humid, and 18 per cent in the semi-arid and arid regions.
6. Climate-adjusted net primary productivity increased across 16 per cent of the country: over 80 per cent of this land is grassland and scrub.
Key words: land degradation/improvement, remote sensing, NDVI, rain-use efficiency, net primary productivity, land use/cover, Argentina
