DFG Trilateral collaboration Deutschland-Israel-Palestine: "Biotic and abiotic factor affecting biological soil crust formation and recovery in a semiarid dune ecosystem : Gaza and NW Negev"

巴勒斯坦加沙地带和以色列内盖夫西部干旱/半干旱沙丘地的沙质土壤广泛覆盖着生物土壤结皮（BSC），具有稳定地表和防止荒漠化的作用。以色列的政治讨论建议在最终和平协议中将这一沙带的大部分转移到加沙地带。不适当的土地使用可能导致平衡平衡系统的破坏并引发荒漠化，加沙地带部分地区已经出现了这种情况。在这个跨学科的项目中，环境因素对平衡计分卡的活力、稳定性和恢复潜力的影响将被调查，以评估这一脆弱景观的承载能力，与降雨、土壤和救援条件有关。选择了从地中海沿岸巴勒斯坦加沙地带（370毫米降雨量）到向南65公里的以色列（尼扎纳，降雨量< 100毫米）的样带。分子生物学、生理、物理和土壤化学过程的相互作用，表达在平衡计分卡和下层土壤的特定特征中，将从分子尺度到景观尺度进行评估。

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.
