This paper analyses informal networks and their utilisation during a period of water scarcity in an upstream and a downstream district in the Khorezm Province, Uzbekistan. The evaluation is based on an organisational theory approach on informal networks. Communication patterns between farm managers, district water departments and district governors in a year with a sufficient amount of water and in a year of water scarcity are compared with informal network structures. The analysis shows that in the year of water scarcity an informal network was utilised to receive water. The importance of the informal network increased with increasing experience and individual perception of water scarcity. The findings confirm the assumption that informal networks are utilised more frequently when formal networks fail or are not functional. The case study therefore confirms the importance of an informal network during a crisis.
