Areas affected by land degradation in Sub-Saharan West Africa between 1982 and 2012 are identified using time-series analysis of vegetation index data derived from satellites. ... It has been widely used to study desertification and other forms of land degradation in drylands. ... Special thanks to CRU for providing the CRU v3.21 rainfall data and NOAA-NCEP for CPC soil moisture (v2) data. ...doi:10.3390/rs70505471 fatcat:hip3b4rqbfhbrba2vdmfrmm3xi
Using a set of robust statistical metrics on the Normalized Difference Vegetation Index (NDVI3g) for precipitation and temperature over 34 years from 1982 to 2015, relevant results were obtained. ... Temperature is increasing while rainfall is decreasing, both at a sharp rate in central Africa. ... Conflicts of Interest: The authors declare that there is no conflict of interest.

This thesis aims to assess vegetation and land cover change in the context of land degradation in the sub-Saharan West Africa, a hotspot of environmental change. ... region, particularly when a soil moisture index is used in the residual trend analysis to correct for vegetation productivity instead of instantaneous rainfall. ... Land Degradation Assessment Using Residual Trend Analysis of GIMMS NDVI3g, Soil Moisture and Rainfall in Sub-Saharan West Africa from 1982 to 2012. ...fatcat:apjlluw7tnfzzafmq24tu4wknu
Using the GIMMS-NDVI, GHCN-CAMS and NCEP reanalysis datasets and statistical and physical diagnostic methods, we show that the summer (June, July and August) NDVI over the eastern Tibetan Plateau and Lake ... Baikal and its adjacent eastern region of Siberia have an in-phase co-variability, especially on an interannual timescale (with a correlation coefficient of 0.69 during the time period 1982-2014). ...
