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.

Abstract. Stakeholder participation is increasingly discussed as essential for sustainable water resource management. Yet detailed understanding of the factors driving its use, the processes by which it is employed, and the outcomes or achievements it can realise remains highly limited, and often contested. This understanding is essential to enable water policy to be shaped for efficient and effective water management. This research proposes and applies a dynamic framework that can explore in which circumstances environmental stress events, such as floods, droughts or pollution, drive changes in water governance towards a more participatory approach, and how this shapes the processes by which participation or stakeholder engagement takes place, and the subsequent water management outcomes that emerge. The framework is able to assess the extent to which environmental events in combination with favourable contextual factors (e.g. institutional support for participatory activities) lead to good participatory processes (e.g. well facilitated and representative) that then lead to good outcomes (e.g. improved ecological conditions). Through applying the framework to case studies from the literature it becomes clear that environmental stress events can stimulate participatory governance changes, when existing institutional conditions promote participatory approaches. The work also suggests that intermediary outcomes, which may be tangible (such as reaching an agreement) or non-tangible (such as developing shared knowledge and understanding among participants, or creating trust), may provide a crucial link between processes and resource management outcomes. If this relationship can be more strongly confirmed, the presence or absence of intermediary outcomes may even be used as a valuable proxy to predict future resource management outcomes.

It is widely recognized that the hydrological regime of natural flow plays a primary and crucial role in influencing the physical condition of habitats, which, in turn, determines the biotic composition and sustainability of aquatic ecosystems. The current hydro-ecological understanding states that all flow components might be considered as operational targets for water management, starting from base flows (including low flows) to high and flood regimes in terms of magnitude, frequency, duration, timing, and rate of change. Several codes have been developed and applied on different case studies in order to define common tools to be implemented for Eflow assessment. This work deals with the definition of an operative procedure for the evaluation of the Eflow monthly distribution to be adopted in a generic watercourse cross-section for sustainable surface water resource management and exploitation. The methodology proposes the application of the Indicators of Hydrologic Alteration methodology (IHA by TNC) coupled to the valuation of the Index of Hydrological Regime Alteration (IARI by ISPRA) as an operative tool to define the ecological flow in each monitoring cross-section to support sustainable water resource management and planning. The case study of the Agri River in Basilicata (Southern Italy) is presented. The analyses were carried out based on monthly discharge data derived by applying the HEC-Hydrological Modeling System at the basin scale using the daily rain data measurements obtained by the regional rainfall gauge stations and calibrated through the observed inlet water discharge registered at the Lago del Pertusillo reservoir station.

Hydro-economic models (HEMs) constitute useful instruments to assess water-resource management and inform water policy. In the last decade, HEMs have achieved significant advances regarding the assessment of the impacts of water-policy instruments at a river basin or catchment level in the context of climate change (CC). This paper offers an overview of the alternative approaches used in river-basin hydro-economic modelling to address water-resource management issues and CC during the past decade. Additionally, it analyses how uncertainty and risk factors of global CC have been treated in recent HEMs, offering a discussion on these last advances. As the main conclusion, current challenges in the realm of hydro-economic modelling include the representation of the food-energy-water nexus, the successful representation of micro-macro linkages and feedback loops between the socio-economic model components and the physical side, and the treatment of CC uncertainties and risks in the analysis.

Abstract The main objective of this research paper is to assess the extent to which the concept of water accounting has been applied for water management at the river basin scale in India. For this, the study first assesses the importance given to the use of water accounting for water management in India's national water policy. It then analyses the evolution of water accounting approaches in India through a systematic review of the past research studies on the theme. Further, it looks at their contribution to decision-making concerning allocation of water resources and resolving conflicts over water sharing. Finally, it identifies the existing gaps in the methodologies for water accounting so far used in India.

Sustainable utilization of peatland is required for balancing production and conservation efforts. On peatland, one of the main components to examine sustainability is understanding the carbon balance. This research was conducted in Pulau Burung, Riau, Indonesia, which has a long history of peatland utilization for agriculture. The sets of utilized data included historical data of water management on peatland represented by water table and subsidence rate, next to carbon density of peat soil. The results showed the function of integrated water resource management made the yearly average water table depth is 48 and 49 cm in 2018 and 2019, respectively. The range water table is between 31cm to 72 cm due to season variability and crop requirement. Consequently, the rate of annual subsidence is averaging at 1.7 cm with cumulative subsidence in 32 yr is 54.1 cm. Since the water never drained since the establishment, the subsidence rate of the first five years is averaging only at 3.3 cm yr–1. Low subsidence rates minimize annual carbon loss during the peatland utilization around (30 to 200) Mg CO2 ha–1 yr–1. In 32 yr, the water management in peatland utilization in Pulau Burung has prevented 2 000 Mg CO2 ha–1 to 4 925 Mg CO2 ha–1 loss compared to other cultivated areas in peatland. Further, this paper discusses the practice that resulted in low emission of coconut agriculture in Pulau Burung as one of sustainability dimensions, which support the other sustainability aspects, that is the thriving local livelihood.

 Maximum and minimum streamflow are fundamental for water resource management, especially for water rights. However, lack of monitoring and scarce streamflow data limit such studies. Streamflow regionalization is a useful tool to overcome these limitations. The study developed models for regionalization of the maximum and minimum reference streamflows for the Mortes River Basin (MRB) (Water Resources Planning and Management Unit - GD2), Southern Minas Gerais State. The study used long-term streamflow historical series provided by the Brazilian National Water Agency (ANA). Previous exploratory analysis was performed, and it was observed that the streamflow series are stationary according to the Mann-Kendall test. The estimation of the streamflow for different return periods (RP) was performed by fitting Probability Density Functions (PDFs) that were tested by the Anderson-Darling (AD) test. The Generalized Extreme Values (GEV) and Wakeby were the most appropriate PDFs for maximum and minimum streamflows, respectively. The streamflow models were fitted using a power regression procedure, considering the drainage area of the watersheds as inputs. The fittings reached the coefficient of determination (R2) greater than 0.90. Thus, the streamflow regionalization models demonstrated good performance and are a potential tool to be used for water resource management in the studied basin.
