“…In response to these, governments around the world are incorporating innovative water management embodiments that are more sustainable than conventional water management. Such paradigms include integrated urban water management, sustainable cities, or total water cycle management, combined with the facilitation of technologies like geo mapping and cybernetics [6,7]. Implementa-tion of these frameworks involves many stakeholders from the federal government to the general public.…”

The water situation in Southeast Asia has changed from one of relative abundance to one of relative scarcity. Conventional water management that strategized around the provision of adequate water supply to users has limited sustainability. Though nations in this region have adopted the United Nations Sustainable Development Plan into their water management framework, successful outcomes are limited thus far. Water literacy has a growing importance for improving water sustainability, especially in developing countries. A literature search was employed to extract data on the different dimensions of water literacy in Southeast Asia including the sources and consumption patterns, water governance and management, and sociodemographic elements as well as the various aspects of water related challenges faced. Results from the review and analysis show that a large proportion of Southeast Asian populations are not part of a water sustainable society, and this presents a major hurdle for the countries to meet United Nations Sustainable Development Goal 6 by 2030. Therefore, active cognitive engagement through the creation of a water literate environment is critical for breaking the chain of water illiteracy and to achieve long-term water sustainability in Southeast Asia countries. Overall, this paper provides a critical analysis on lessons learnt from the region that can be mirrored in other parts of the world.

“…Nitrate enters the soil through infiltration from the surface detention store. Nitrate in the soil is transported by subsurface flow in the saturated zone, while in the unsaturated soil, there is no lateral nitrate transport (B. Chen et al., 2020; Tague & Band, 2004). The amount of nitrate in the unsaturated soil, including root accessible unsaturated soil, is maintained through the balance of input processes (nitrification and N‐deposition) and loss through plant‐uptake, denitrification, and export.…”

Simulating the Role of Biogeochemical Hotspots in Driving Nitrogen Export From Dryland Watersheds

Climate change and nitrogen (N) pollution are altering biogeochemical and ecohydrological processes in dryland watersheds, increasing N export, and threatening water quality. While simulation models are useful for projecting how N export will change in the future, most models ignore biogeochemical “hotspots” that develop in drylands as moist microsites in the soil become hydrologically disconnected from plant roots when soils dry out. These hotspots enable N to accumulate over dry periods and rapidly flush to streams when soils wet up. To better project future N export, we developed a framework for representing hotspots using the ecohydrological model RHESSys. We then conducted a series of virtual experiments to understand how uncertainties in model structure and parameters influence N export to streams. Modeled N export was sensitive to three major factors (a) the abundance of hotspots in a watershed: N export increased linearly and then reached an asymptote with increasing hotspot abundance; this occurred because carbon and N inputs eventually became limiting as hotspots displaced vegetation cover, (b) the soil moisture threshold required for subsurface flow from hotspots to reestablish: peak streamflow N export increased and then decreased with an increasing threshold due to tradeoffs between N accumulation and export that occur with increasingly disconnected hotspots, and (c) the rate at which water diffused out of hotspots as soils dried down: N export was generally higher when the rate was slow because more N could accumulate in hotspots over dry periods, and then be flushed more rapidly to streams at the onset of rain. In a case study, we found that when hotspots were modeled explicitly, peak streamflow nitrate export increased by 29%, enabling us to better capture the timing and magnitude of N losses observed in the field. N export further increased in response to interannual precipitation variability, particularly when multiple dry years were followed by a wet year. This modeling framework can improve projections of N export in watersheds where hotspots play an increasingly important role in water quality.

“…Eco‐hydrological models that quantitatively describe the complex and dynamic relationships between vegetation and water under changing environments are essential for understanding the interactions between ecological and hydrological systems (Chen et al, 2020; Rinaldo et al, 2014; Tague & Frew, 2021). Based on model complexity with respect to the representation of vegetation‐hydrological interactions, eco‐hydrological models can be categorized into conceptual models, semi‐physically based models, and physically based models (Luo & Zuo, 2019; Guswa et al, 2020).…”

Initiatives on exploring the mechanism of eco‐hydrological response to land surface change and adaptive regulation in the Yellow River Basin

The Yellow River Basin faces water scarcity and ecological fragility. Changes on the land surface, characterized by large‐scale soil and water conservation measures, have a significant impact on river runoff and ecological environment. However, there are still great uncertainties in the scientific understanding of the mechanisms by which multiple driver impact eco‐hydrological processes due to the diversity of land surfaces and the complexity of the coupling processes. As an international scientific frontier on interdisciplinary studies in climatology, hydrology, ecology, and other related fields, it is significant to study the mechanisms and assess the impacts of land surface change on eco‐hydrological risk to support ecological restoration plan and sustainable water resources utilization in the Yellow River Basin. Taking the Yellow River Basin as the study area, this study proposes several important research initiatives, focusing on addressing the ecological and water resources problems in the Loess Plateau. These initiatives include (1) to quantify the individual effect of land surface elements (e.g., vegetation, terraces, and check dam) and reveal the nonlinear driving mechanisms of multiple drivers on eco‐hydrological processes; (2) to construct a distributed eco‐hydrological model that couples dynamic land surface features, and simulate eco‐hydrological processes in a changing environment; (3) to improve the ecological risk assessment indicator system and methods for assessing the impacts of land surface changes on eco‐hydrological synergistic functions and ecological risk; (4) to establish an ecological regulation model based on multiobjective game theory and adopt an adaptive regulation mode for ecological risk management. The research could enrich the scientific understanding and theory of eco‐hydrology, and prompt disciplinary studies of ecology, hydrology, climatology, and other fields. The expected academic achievements will innovate eco‐hydrological simulation and assessment techniques in a changing environment, and strongly support the implementation of the national strategy for ecological protection and high‐quality development in the Yellow River Basin.
