Findings from the OECD Survey on Water Resources Allocation indicate that 60% of countries surveyed have recently reformed their allocation regimes. Over half of respondents indicated that allocation reforms are ongoing. In this analysis, "reform” is understood broadly, to encompass both transformational reforms that can entail fundamental changes to significant aspects of an allocation regime, as well as incremental changes in the policies, laws, and mechanisms that have a tangible impact on allocation arrangements.
