auf der Homepage des Verbundprojekts SPACES2 'Südafrika Landdegradationsmonitor (SALDi)'. Das Projekt entwickelt neue Ansätze zur räumlich expliziten Erkennung von Landdegradation in Südafrika. Das Vorhaben wird vom BMBF gefördert.
Die SPACES-Projekte SALDi und EMS Africa führten vom 04. – 08. Juli 2022 eine Schulung zur Erdbeobachtung an der WITS Rural Facility in Acornhoek, Südafrika durch.
Die 3. SALDi Geländekampagne findet von März bis Mitte April 2020 statt und umfasst ausgewählte Untersuchungsgebiete. Der Fokus der Arbeiten liegt auf der Kontrolle der Bodenfeuchtenetzwerke, sowie ergänzende Beregnungsexperimente und ergänzende Vermessungen von Stauseen. Das Bild zeigt eine Beregnung in der Nähe von Ladybrand, Free State im Oktober 2019.
Die 2. SALDi Geländekampagne findet vom September bis Mitte Oktober 2019 statt und umfaßt alle sechs Untersuchungsgebiete. Der Fokus der Arbeiten liegt auf der Kontrolle der Bodenfeuchtenetzwerke, die im März erfolgreich installiert wurden. Zudem werden Vermessungen mit dem Terrestrischen Laserscanner und Beregnungsexperimente durchgeführt.Das Bild zeigt den Testlauf auf den Versuchsflächen des TLLLR in Dornburg am 17.7.2019.
Die 1. SALDi Geländekampagne findet vom 14.3. bis 6.4.2019 statt und umfaßt alle sechs Untersuchungsgebiete. Der Fokus der Arbeiten liegt auf der Installation von Geräten und initialen Geländevermessungen.
Das SALDi Kick-off findet vom 11. bis 13.3.2019 in Pretoria am Agricultural Research Council (ARC), Institute for Soil, Climate and Water (ISCW) statt.
