| Abstract | ||
| ctivity Dynamics (LPD) in Egypt, during the 2000 - 2019 period as well as identifying drivers and hotspots of land degradation aiming at realizing the promotion of the land’s sustainable development and degradation neutrality. The study is based on remotely sensed images (SPOT Vegetation NDVI) aggregated / composited to observation every 10 days at a spatial resolution of 30 m calculated by the Joint Research Centre. Results showed that trends of the net LPD for each of the degraded land cover categories were 0.4%, accounting for about 11415 sq. km (1.14% of Egypt’s land area). On the other hand, the increasing trend of LP has been attained for both of the shrubs and grassland together with croplands, accounting for around 2077 and 10921 sq. km respectively representing together about 1.3 % of the country’s land area. During the study period, mismanagement of soils and water resources has been the chief reasons for the changes in LP. Worthy mentioning, that RS, NDVI and GIS are considered essential tools for LPD monitoring and assessment. | ||
