Land Degradation Assessment Using Residual Trend Analysis of GIMMS NDVI3g, Soil Moisture and Rainfall in Sub-Saharan West Africa from 1982 to 2012

Yahaya Ibrahim, Heiko Balzter, Jörg Kaduk, Compton Tucker
2015 Remote Sensing  
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.  ...

Vincent Nzabarinda, Anming Bao, Wenqiang Xu, Solange Uwamahoro, Liangliang Jiang, Yongchao Duan, Lamek Nahayo, Tao Yu, Ting Wang, Gang Long
2021 Sustainability  
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.

Co-variability of the summer NDVIs on the eastern Tibetan Plateau and in the Lake Baikal region: Associated climate factors and atmospheric circulation

Kejun He, Ge Liu, Junfang Zhao, Jingxin Li, Broxton W. Bird
2020 PLoS ONE  
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).  ...  We are grateful to the anonymous reviewers for their constructive comments.  ...
