Abstract: | A study of aerial photography from 1962 and satellite data from later periods did not indicate any evidence for a continuous Sahara desert movement southwards, large shifts in land system borders, southward sand and dune complex encroachment or systematic growth of village “desert patches”. A study of the potential of a transformed normalized difference green leaf density vegetation indicator for drought impact and green biomass monitoring is in progress. |
