Integrated Water Resource Management

A systems, holistic, or ecosystem approach is often advocated for water management, and has led to the emergence of integrated water resource management, or IWRM. Such an approach can be interpreted as ‘comprehensive’ or ‘integrated’, and analysts, planners, and managers need to understand the difference. Edge or boundary problems always are encountered when applying a holistic approach, and design of institutional arrangements cannot eliminate these problems but can minimize them. IWRM often does not have a statutory basis, which can lead to implementation challenges. By linking IWRM to land-use planning and official plans at the local level, IWRM can be given credibility, as well as be systematically connected to land-based issues.

The Relationship

Increasing water demand due to population growth, economic development, and changes in rainfall patterns due to climate change are likely to alter the duration and magnitude of droughts. Understanding the relationship between low-flow conditions and controlling factors relative to the magnitude of a drought is important for establishing sustainable water resource management based on changes in future drought risk. This study demonstrates the relationship between low-flow and controlling factors under different severities of drought. I calculated the drought runoff coefficient for six types of occurrence probability, using past observation data of annual total discharge and precipitation in the Japanese archipelago, where multiple climate zones exist. Furthermore, I investigated the pattern of change in the drought runoff coefficient in accordance with the probability of occurrence of drought, and relationships among the coefficient and geological, land use, and topographical factors. The drought runoff coefficient for multiple drought magnitudes exhibited three behaviors, corresponding to the pattern of precipitation. Results from a generalized linear model (GLM) revealed that the controlling factors differed depending on the magnitude of the drought. During high-frequency droughts, the drought runoff coefficient was influenced by geological and vegetation factors, whereas land use and topographical factors influenced the drought runoff coefficient during low-frequency droughts. These differences were caused by differences in runoff, which dominated stream discharge, depending on the magnitude of the drought. Therefore, for effective water resource management, estimation of the volume of drought runoff needs to consider the pattern of precipitation, geology, land use, and topography.

Quantitatively figuring out the effects of climate and land-use change on water resources and their components is essential for water resource management. This study investigates the effects of climate and land-use change on blue and green water and their components in the upper Ganjiang River basin from the 1980s to the 2010s by comparing the simulated changes in blue and green water resources by using a Soil and Water Assessment Tool (SWAT) model forced by five climate and land-use scenarios. The results suggest that the blue water flow (BWF) decreased by 86.03 mm year−1, while green water flow (GWF) and green water storage (GWS) increased by 8.61 mm year−1 and 12.51 mm year−1, respectively. The spatial distribution of blue and green water was impacted by climate, wind direction, topography, and elevation. Climate change was the main factor affecting blue and green water resources in the basin; land-use change had strong effects only locally. Precipitation changes significantly amplified the BWF changes. The proportion of surface runoff in BWF was positively correlated with precipitation changes; lateral flow showed the opposite tendency. Higher temperatures resulted in increased GWF and decreased BWF, both of which were most sensitive to temperature increases up to 1 °C. All agricultural land and forestland conversion scenarios resulted in decreased BWF and increased GWF in the watershed. GWS was less affected by climate and land-use change than GWF and BWF, and the trends in GWS were not significant. The study provides a reference for blue and green water resource management in humid areas.

Sustainable Water Resource Management

Human uses of land and water are directly linked and must, therefore, be managed with each other in mind. This paper puts forward an approach for integrating sustainable water resource management into local land use decision-making in the Potomac basin. The approach includes developing a clear understanding of the current regulatory, programmatic, and financial approaches to land use management; identifying opportunities from innovation; and developing a flexible, stakeholder-based framework for moving forward. Four opportunities for innovation were identified in the Potomac basin utilizing this approach, including enhancing coordination and access to information, promoting incentives to achieve desired outcomes, encouraging and promoting innovation, and integrating programs to achieve multiple objectives. The successful integration of land and water decision-making requires a sustained, long-term commitment to improvement rather than a one-time fix mentality. Initial steps for implementation include identifying and engaging diverse partners, as well as establishing channels for information dissemination. The lessons learned from this work may prove valuable to decision-makers in other regions to holistically manage diverse land and water resources.

The availability of water resources in southern Alberta is under pressure, now and most likely even more so in the remainder of the 21st century if forecasts on climate change, economic development and associated population growth come true. Alberta Environment is mandated by the provincial Water Act to regulate most use of water through a system of water licenses. This department is currently using a water resource management model (WRMM) to support its planning, but wishes to expand the reach of its decision support tools by including additional factors such as the land-use dynamics. This paper presents the coupling of the WRMM and a land-use cellular automata (CA) model to constrain land development based on water availability in the Elbow River watershed in southern Alberta. Simulations were run with a calibrated CA model using a land-use map of 2006 as the starting year up to the year 2031, at a five-year interval and at a spatial resolution of 60 m. Two scenarios were tested: the business as usual scenario, which is a simple extrapolation of observed historical land development, expressed as the number of built-up cells, and a second scenario in which land development is constrained based on the WRMM water availability output. Results indicate that land development varies in terms of growth and spatial distribution when comparing the two scenarios. The potential benefits and limitations of the two models are discussed and further improvement needed to increase their usefulness in guiding water resource management is highlighted.
