A key tenant of risk reduction models in archaeology the world over is that changes in resource availability drove mobility increases and created a need for an extension of stone tool use life. This manuscript directly addresses the question, is retouch intensity of tools related to distance from freshwater, by using extant localities of major Gorges, Rivers and water holes in the southern Kimberley region of northern Australia. Previous research has argued that retouched stone points during the mid to late-Holocene were part of a risk minimisation strategy, within broader technological organisation models. Modelling the distance from primary water sources, in arid to semi-arid regions of the southern Kimberley, reduction intensity of points is found to increase with distance from water sources consistently. This research provides an appropriate test of existing risk minimisation models and highlights global significance for similar studies where retouch tool reduction and forager mobility are linked to environmental change.

世界各地考古学中风险降低模型的一个关键租户是，资源可用性的变化推动了流动性的增加，并产生了延长石器使用寿命的需求。这份手稿通过使用澳大利亚北部金伯利南部地区主要峡谷、河流和水坑的现存地点，直接解决了与淡水距离相关的工具润饰强度的问题。先前的研究认为，在更广泛的技术组织模型中，全新世中期至晚期经过修饰的石点是风险最小化策略的一部分。在金伯利南部干旱到半干旱地区模拟与主要水源的距离，发现点的减少强度随着与水源的距离不断增加而增加。
