Eastern Cape Province in South Africa has experienced extreme drought events during the last decade. In Africa, different land management systems exist belonging to two tenure classes: commercial large scale farming and communal small-scale subsistence farming. Communal lands are often reported be affected by degradation among others considered as trigger for this process. Against background, we analyzed vegetation response through assessing productivity trends monitoring intensity,...
Mangroves ecosystems dominate the coastal wetlands of tropical and subtropical regions throughout world. They are among most productive forest ecosystems. provide various ecological economic ecosystem services. Despite their importance, mangroves experience high yearly loss rates. There is a growing demand for mapping assessing changes in extents especially context climate change, land use related threats to The main objective this study develop an approach on Red Sea coastline Egypt,...
This study evaluates the potential of repeat-pass synthetic aperture radar interferometry (InSAR) coherence for grasslands monitoring in Eastern Cape Province, South Africa. We used 12 pairs InSAR data Interferometric Wide swath mode (IW), VV-polarization (with different spatial baseline B⊥ and temporal repeat intervals between subsequent acquisitions), covering area during two growing seasons; drought season (2015/2016) non-drought (2016/2017). Results show that has higher variability...
Grasslands are a major component of the natural vegetation in South Africa, it covers almost one-third country's land surface. The current study focuses on assessing impact drought stress communal and commercial grasslands Eastern Cape Province using multi-temporal analysis Sentinel-1 SAR data. Data included retrieval biophysical parameters backscattering coefficients. Correlation was performed between data NDVI values derived from Landsat-8 optical A linear mixed-effects regression for...
Drought is one of the most severe natural disasters with a high risk for human livelihoods. Remote sensing based drought indices can identify dry periods using, e.g., precipitation or vegetation information. Besides frequency, duration, and intensity, timing onset duration are important variables to measure impact risk. This article classifies events on regard their production during different crop growing stages. nondrought seasons analyzed in Eastern Cape Province, South Africa. Here,...

Drought is one of the most severe natural disasters with highest risk for human livelihoods. Remote sensing based drought indices can identify dry periods using e.g. precipitation or vegetation information. Besides frequency, duration and intensity, timing a onset an important variable to measure risk. This study classifies events on onsets duration. non-drought seasons are analyzed in two sites South Africa Ukraine where characteristics different. highly depends starting point rainfall,...
