This article provides an evidence-based and policy-relevant contribution to understanding the phenomenon of policy learning and its structural constraints in the field of river basin management, in particular related to coping with current and future climatic hazards such as floods and droughts. This has been done by a formal comparative analysis of eight water management regimes, by using multi-value qualitative comparative analysis, focusing on the relationship between regime characteristics (as explanatory variables) and different levels of policy learning (as output value). This research has revealed the importance of the sociocognitive dimension, as an essential emerging property of complex adaptive governance systems. This socio-cognitive dimension depends on a specific set of structural conditions; in particular, better integrated cooperation structures in combination with advanced information management are the key factors leading towards higher levels of policy learning. Furthermore, this research highlights a number of significant positive correlations between different regime elements, thereby identifying a stabilizing mechanism in current management regimes, and this research also highlights the necessity of fine-tuning centralized control with bottom-up approaches.
Through the lens of the 12 OECD Principles on Water Governance, this paper examines six water resources and water services frameworks in Europe, Asia-Pacific, Africa and South America to understand enhancing and constraining contextual factors. We use qualitative and quantitative methods to analyse each framework against four criteria: alignment; implementation; on-ground results; and policy impact. We identify four main target areas for improving water governance: policy coherence; financing; managing trade-offs; and ensuring integrity and transparency by all decisionmakers and stakeholders. We present suggestions to support practical implementation of the principles through better governmental action and stakeholder involvement.
Despite huge differences in population, household income and development levels, Australia and Brazil have some temporal convergences in their water governance systems. Over the last 20 years, both countries have significantly reformed their water policies and practices by introducing a legal foundation for more integrated and participatory catchment/basin management based on the best information available. A critical test of any water reform is how effective it is in meeting the challenges of extreme and unpredictable conditions of drought and floods, which are expected to increase under climate changes scenarios. This paper compared the contemporary water governance frameworks of Australia and Brazil in relation to three elements of Integrated Water Resources Management (IWRM): integration, participation, and information/knowledge. We focused on insights from Brazil's recent drought and Australia's fluctuating water crises to derive lessons and recommendations for future changes. Among the main recommendations, we stress the need for both systems to improve effective participation and to embrace a more comprehensive approach to cope with water scarcity in future scenarios. Furthermore, water related decisions should be based on a transparent and well informed process, and take into account the lessons from similar situations worldwide in order to avoid unnecessary or ineffective measures. As demonstrated in the Australian case during the Millennium Drought, the most effective initiatives were those involving government, the private sector and society to achieve a more sustainable consumption pattern in all sectors. There is much to learn from the Brazilian and Australia experiences in water reforms and crises, but it is imperative to understand the social, economic and environmental context within which these took place. Continuing to develop the capacity and willingness of researchers and policy makers to work together can make an important contribution towards meeting the growing and spreading challenges in water resource management around the world.
