LABURPENA: Espainiako Zuzenbidea Uraren Zuzentarau Markora egokitzeko prozesua asko ari da atzeratzen. Espainiako Zuzenbidean arroen araberako kudeaketa-irizpideak badu tradiziorik; hori horrela izanik, harrigarria dirudi plangintza- eremuak mugatzeak horrelako zailtasun larriak ematea. Zailtasun horien atzean, ordea, Estatuaren eta autonomia erkidegoen arteko botere-banaketaren arteko barne-kontraesanak daude, uraren kudeaketari dagokionez. Uren Legearen Testu Bategina koherentziaz aplikatu ezin denez, zenbait konponbide heterogeneo ari dira sortzen; horietako batzuek, ordea, nekez izango dute tokirik Konstituzioan, uraren kudeaketa jasangarriari traba egiten baitiote, bai ingurumenaren aldetik, bai gizartearen ikuspegia aintzat hartuta. RESUMEN: La transposición de la Directiva Marco de Aguas a Derecho español se está realizando con notable retraso. Y en este punto, resulta sorprendente que siendo el principio de gestión por cuencas tradicional en Derecho español, ya la mera delimitación de los ámbitos de planificación esté suponiendo graves dificultades. En realidad, tras estas dificultades lo que se esconde una acumulación de contradicciones internas en el reparto de poder entre el Estado y Comunidades Autónomas en el ámbito de la gestión hidrológica. Ante la incapacidad de aplicar de forma coherente el Texto Refundido de la Ley de Aguas, están surgiendo una serie de soluciones heterogéneas, algunas de las cuales de difícil encaje constitucional, que entorpecen una gestión sostenible del recurso tanto social como ambientalmente. ABSTRACT: Spain has not complied with the timetable established in the Water Framework Directive. Difficulties have started with the establishment of river basin districts. And this is surprising, because, according to the Spanish model, water management must be done in the natural framework of river basins. Furthermore, in fact, these difficulties what is left is an accumulation of internal contradictions in the distribution of power between the State and Autonomous Regions in the field of water management. Given the inability to consistently apply the Water Law, heterogeneous solutions are emerging, some of which doubtfully constitutional, that hinder the sustainable resource management both socially and environmentally.

AbstractSweden is a decentralised country where local managers, who are key actors in water management, often deal with relatively difficult prioritisations, tradeoffs and conflicting goals. Many of these challenges relate to the effective implementation of the European Union Water Framework Directive. As an input to these challenges, the present paper elicits and analyses local and semi-local citizens’ preferences for water quality attributes related to the European Water Framework directive in a river basin located in southeast of Sweden. Based on a choice experiment tailored to the case study area, the paper analyses preferences for selected attributes based on real criteria for ecological water status in the implementation of the directive. The target population lives in the municipalities through which the river passes, or in municipalities neighbouring those. Despite this spatial proximity to the river, the analysis reveals limited knowledge and interest in matters related to the environmental quality of the river. There is no evidence that preferences differ between respondents with regard to experience or knowledge about the water basin, nor with regard to recreational habits in the area. These results offer input to local water management by providing information about preferences for explicit water quality attributes.

River management has frequently been associated with water supply and resource management, whereas coastal zone management has been more concerned with marine resource management and physical planning. Recognizing the close connection between the river and its catchment area has led to a more integrated approach to river basin management, taking into account water quality along with quantity. Similarly, recognition of the importance of integrated management of the coastal zone as a move towards achieving sustainable development, has led to integrated coastal zone management, with expansion of the domain in both landward and seaward directions. Considering the intrinsic link through physical and ecological structure as well as related physical and biological processes, any modification in a river basin will ultimately affect the coastal zone. Land-based activities, rivers, estuaries, coastal zones and marine environments are all inherently interlinked. As such, an integrated approach to the concomitant management of coastal zones and river basins is crucial. This paper provides an overview of various concepts, approaches and strategies to integrated coastal zone and river basin management. It points out lessons that could be learned from previous and ongoing projects. The paper provides a starting point for investigating how changes in land use and management of river basins might have an impact on the quality of river water and the corresponding coastal zone through scrutinization of management tools and implementation instruments. The paper identifies a requirement further to develop tools which will assist in evaluating current and future environmental conditions at a river/estuary/sea interface within a rigorous framework.

Abstract Since 2011, China has implemented its most stringent water management system to effectively protect water resources and guarantee socioeconomic development. More basin-scale water division schemes have been developed to act as references for basin-scale water resources management. Water dispatching during dry periods is an effective way to guarantee the water supply for the river basin, and is also an important component of basin-scale water resources management. Given this, the present study proposes a framework for the water dispatching of river basins during dry periods under the most stringent water management system in China. This framework mainly consists of the analysis and forecasting of rainfall and inflow, the dispatching requirements for the main water users, major reservoirs, and sections, as well as safeguard measures. The Jian River Basin in South China is presented as a case study. The total discharge of the Gaozhou Reservoir in 2017 was 25 million m3 more than the target discharge specified in the water dispatching scheme, and the total water storage utilization ratio during the dispatch period was 4.7% higher than the target utilization ratio. These factors demonstrate the effectiveness and applicability of the proposed framework. HIGHLIGHT The proposed framework for the water dispatching of river basins during dry periods provides reliable technical support for water use security under the most stringent water management system in China, and is demonstrated to be both effective and applicable.

Abstract. Water management in sub-Saharan African river basins is challenged by uncertain future climatic, social and economical patterns, potentially causing diverging water demands and availability, as well as by multi-stakeholder dynamics, resulting in evolving conflicts and tradeoffs. In such contexts, a better understanding of the sensitivity of water management to the different sources of uncertainty can support policy makers in identifying robust water supply policies balancing optimality and low vulnerability against likely adverse future conditions. This paper contributes an integrated decision-analytic framework combining optimization, robustness, sensitivity and uncertainty analysis to retrieve the main sources of vulnerability to optimal and robust reservoir operating policies across multi-dimensional objective spaces. We demonstrate our approach onto the lower Umbeluzi river basin, Mozambique, an archetypal example of sub-Saharan river basin, where surface water scarcity compounded by substantial climatic variability, uncontrolled urbanization rate, and agricultural expansion are hampering the Pequenos Lipompos dam ability of supplying the agricultural, energy and urban sectors. We adopt an Evolutionary Multi-Objective Direct Policy Search optimization approach for designing optimal operating policies, whose robustness against social, agricultural, infrastructural and climatic uncertainties is assessed via robustness analysis. We then implement the GLUE and PAWN uncertainty and sensitivity analysis methods for disentangling the main challenges to the sustainability of the operating policies and quantifying their impacts on the urban, agricultural and energy sectors. Numerical results highlight the importance of robustness analysis when dealing with uncertain scenarios, with optimal-non robust reservoir operating policies largely dominated by robust control strategies across all stakeholders. Furthermore, while robust policies are usually vulnerable only to hydrological perturbations and are able to sustain the majority of population growth and agricultural expansion scenarios, non-robust policies are sensitive also to social and agricultural changes, and require structural interventions to ensure stable supply.

This symposium presents an opportunity to discuss agricultural sustainability. But we have little practical understanding of what agricultural sustainability really means. This is a common problem with sustainability efforts. This Article provides one example of this problem. But it also provides a story of how an effort at defining sustainability served as a catalyst for a group of stakeholders that wanted to make improvements in water management. Understood in this way, sustainability discussions can serve to overcome historic barriers to progress that so often arise with resource management problems, especially in the agricultural sector.

Abstract Contrary to dominant paradigms, the river basin is not the obvious unit within which to undertake water management given the diversity of functions inherent in water resource management. The Southern African experience is presented to illustrate issues that may arise when using the river basin for different functions. Functions best addressed at a larger ‘problem-shed’ level are identified and it is explained why some other functions should rather be performed at smaller, sub-basin scales. Using recent work on water governance, which emphasise polycentricity and network governance, it is suggested that a better understanding of the appropriate scales for different functions will support activities such as planning, monitoring and the protection of the aquatic environment that may best be focused at river basin scale.

Modern river basin management techniques are gaining popularity in China to effectively manage increasingly vulnerable water resources. China has several large river basins, with a variety of resource conditions and development challenges. River basins in China are facing aggravated water pollution, and development and management issues. In dealing with these issues, and in line with the evolution of modern concepts of river basin management, the 2002 Water Law of People's Republic of China for the first time defines river basin management institutions and functions, the legal status of river basin management organizations in China, and strengthens the administrative rights of river basin management organizations. However, although it is a good beginning, it is far from perfect. There are still several key issues which need to be addressed in the future, such as: function clarification, relationships between river basin management and jurisdictional management, participation, and coordination and integration of natural resources management.

Three Rivers

In recent years, the ‘river basin as a management unit’ approach has been adopted as a solution to water management. The situation between Swaziland, Mozambique and South Africa regarding managing the water resources of the Incomati, Maputo, and Umbeluzi shared river basins is an interesting case that might need a different approach. These rivers flow downstream to the Maputo estuary where their waters are needed for urban water supply (Maputo city) and fresh water pulses for the estuary. The Incomati and Umbeluzi are heavily committed upstream while the Maputo appears still to have a relative abundance of untapped water resources. At basin level, the three countries fail to reach a consensus on the best strategies to accommodate multiple demands, particularly in the downstream area. The IncoMaputo agreement that was concluded by the three governments is unique in that it comprises two basins (Maputo and Incomati), allowing a multi-basin approach to the problem. However, the Umbeluzi was left out of the agreement. This paper discusses the possible benefits of a multi-basin approach to water resources for the three rivers discharging into Espírito Santo Estuary in Maputo. Using the provisions set out in the European Union Water Framework Directive (WFD) it is found that the three rivers of this study may well be suitable for implementing the District Water Management approach as proposed in the WFD.
