In our new publication”Optimising Phenological Metrics Extraction for Different Crop Types in Germany Using the Moderate Resolution Imaging Spectrometer (MODIS)” we present a calibration procedure to make phenometrics more comparable to ground-based phenological stages. Therefore we optimised the settings of the Best Index Slope Extraction (BISE) and smoothing algorithms together with thresholds applied to the resulting smoothed NDVI curves.

In our new publication “Quantifying water volumes of small lakes in the inner Aral Sea Basin, Central Asia, and their potential for reaching water and food security” we combined remote sensing based lake surface areas with bathymetric models derived from field measurements. The study explores the potentials of the lake water for supplementary irrigation in drought periods and rises the question about potential effects of improving irrigation efficiency on the existence of valuable lake ecosystems in the region.

PhD defense by Benewinde Jean-Bosco Zoungrana

Photo_1On April 19 2016 Benewinde Jean-Bosco Zoungrana successfully defended his PhD  “Vegetation cover response under rainfall variability and land use/cover change  in the southwest of Burkina Faso” dealing with remote sensing for land cover and vegetation mapping in West Africa at the Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana– congratulations! Jean-Bosco is a member of the graduate school “Land use and climate change in West Africa” at KNUST. He visited our department during his Phd two times, altogether he stayed for 6 months. Dr. Michael Thiel was his mentor in Germany.

Dr. Zoungrana conducted an excellent research, out of which he already published two scientific papers. The third manuscript is almost ready for submission.

CAWa project: First National WUEMoCA User Forum in Uzbekistan

CAWa project: First National WUEMoCA User Forum in Uzbekistan

In the test version, WUEMoCA provides information on land use, crop yields for cotton and wheat, and land use intensity – as shown here for the region around Tashkent and Fergana.

On 10 December 2015, the first National WUEMoCA (“Water Use Efficiency Monitor in Central Asia”) User Forum was held in Tashkent (Uzbekistan). The meeting gathered 20 representatives from the Basin Water Organisations Amudarya and Syrdarya, Basin Irrigation System Administrations, Irrigation System Administrations, and research institutions from all over Uzbekistan. Researchers and WUEMoCA developers from Wuerzburg University and SIC ICWC presented the preliminary version of the WUEMoCA web-tool, and discussed the specific requirements by users in irrigation management organisations.

In our new publication “Evaluating the sequential masking classification approach for improving crop discrimination in the Sudanian Savanna of West Africa” we investigated the benefit of sequential masking on the accuracy of crop mapping in the heterogeneous landscapes of the Sudanian Savanna in West Africa.
