hide abstract This research is entitled ‘Arid landscape dynamics along a precipitation gradient : addressing vegetation – landscape structure – resource interactions at different time scales’ with as subtitle ‘A case study for the Northern Negev Desert of Israel’. Landscape dynamics describes the interactions and feedbacks among landscape structure, resource flows and organisms. This study focuses on the Northern Negev Desert of Israel, a semi-arid to arid rock desert with local loess and sand cover. Climate and humans are important driving factors of landscape dynamics here. Semi-arid and arid regions worldwide, are vulnerable to land degradation and desertification. A profound knowledge of the processes in these regions can help to avert land degradation and desertification. The objective of this thesis is to increase the knowledge on landscape dynamics and its drivers in semi-arid and arid regions by field and model studies in the Northern Negev Desert. This study can contribute to a sustainable future for the inhabitants of these areas.
