This article presents a comprehensive examination of commonly usedmethodologies for assessing the risk of water scarcity in various global research initiatives. The acquisition of knowledge associated with these methods serves the dual purpose of augmenting comprehension and importance of water scarcity while also providing additional tools to strengthen the effectiveness of water resource management strategies, thus promoting the advancement of sustainable development. Water scarcity risk assessment involves two main approaches: the IPCC risk assessment framework, which primarily evaluates the risk of water scarcity within a nation, and the virtual water-based approach, which primarily assesses the risk of water scarcity at the regional level. The IPCC risk framework consists of three essential components: hazards, exposures, and vulnerabilities. The concept of virtual water-based water scarcity risk refers to the prospective economic consequences faced by industries due to the scarcity of water resources. This impact encompasses both the direct loss of output and the indirect loss of output through trade.
