Sandy soils of the arid/semiarid dune fields of the Palestinian Gaza Strip and the Israeli western Negev are extensively covered by biological soil crusts (BSC), which stabilize the surface and prevent desertification. Political discussions in Israel suggest transferring a large part of this sand belt to the Gaza Strip within a final peace accord. Inappropriate land uses may lead to destruction of the BSC and initiate desertification, as already occurring in parts of the Gaza Strip. In this interdisciplinary project the influence of environmental factors on the vitality, stability and the recovery potential of the BSC will be investigated in order to evaluate the carrying capacity of this fragile landscape, in relation to rainfall, soil and relief conditions. A transect stretching from the Mediterranean coast in the Palestinian Gaza Strip (370 mm rainfall) to 65 km southwards in Israel ( Nizzana , < 100 mm rainfall) has been selected. The interactions of molecular biological, physiological, physical and soil chemical processes, expressed in specific characteristics of the BSC and the underlying soil, will be assessed from the molecular to the landscape scale.

巴勒斯坦加沙地带和以色列西部内盖的干旱/半干旱沙丘田的沙质土壤被生物土壤外壳（BSC）广泛覆盖，从而稳定表面并防止沙漠化。以色列的政治讨论建议将这条沙带的很大一部分转移到最终和平协议中。不适当的土地用途可能会导致BSC的破坏并启动荒漠化，就像加沙地带的部分地区一样。在这个跨学科项目中，将研究环境因素对BSC活力，稳定性和恢复潜力的影响，以评估与降雨，土壤和救济条件有关的脆弱景观的承载能力。已经选择了从巴勒斯坦加沙地带的地中海海岸（370毫米降雨）延伸到以色列向南65公里的横断面（Nizzana，<100 mm降雨）。分子生物学，生理，物理和土壤化学过程的相互作用将以BSC和基础土壤的特定特征表达，从分子到景观量表进行评估。
