“…For example, the Analytic Hierarchy Process method is commonly used to calculate the weights of indicators for assessing HER [23]. Multi-objective Models are often used to analyze the integration and optimization of water systems, and to coordinate the relationship between the humanistic system and the water system [24]. The drivers, pressure, state, impact and response (DPSIR) framework is an important method for identifying the interaction relationship between indicators of human-water system [25,26].…”

The conflict of the human-water relationships (HWR) has further increased the water-related risks, such as water environment deterioration, water shortages, and even regional violent conflicts for obtaining usable water resources. Knowing how to evaluate and regulate the discordant HWR to form a balanced growth between sustainable socio-economy and water resources protection has become a critical issue in water resources management. The harmony theory method, which provides a new perspective for solving the conflict between humans and water, has been widely used in current studies. However, this method focuses less on the quantitative study of the balance status of HWR. This study proposes a harmony theory-based HWR evaluation method that contains a systematic process of harmony assessment, indicator identification, harmony balance constraints, and harmony regulation for assessing and regulating the discordant HWR. The Henan Province of China, which has a complicated HWR, was selected as a case study to apply and verify the approach proposed in this study. The results indicated that (1) Henan Province showed a poor harmony status. The human–water harmony degree of 18 distinctions in the province varied from 0.41 to 0.76, showing an increasing trend from 2006 to 2018, indicating that the HWR was gradually improving in recent years. (2) The human–water harmony degree showed that HWR in the southwest part of Henan Province, with less human activities, was better than that in its northeast part, which had faster social development. Sanmenxia City, located in the west part of the province, had the highest human–water harmony degree because of the recent water control projects implemented in the city, indicating that human production measures could effectively help improve HWR. (3) At present, Henan Province has serious discordant indicators in these three aspects (water system health, humanistic system development, and human-water system coordination), which proves that it is still facing pressure from both socio-economy sustainable development and water resources protection. Our results provide insight into water resources management in Henan Province and other similar regions.

“…The benefits of GI adaptation are that it can easily link with the pre-existing gray infrastructure [34]. For this reason, cities around the world are implementing them, often after a weather-related crisis [70]. These strategies are a compelling necessity in the current climatic change context, especially in arid and semi-arid zones.…”

The increasing population and urban sprawl will continue to add significant pressure to natural resources in arid and semi-arid zones. This study evaluates the theoretical effectiveness of adapting resilient strategies such as water conservation and green infrastructure to mitigate the water scarcity faced by the inhabitants of a residential area with a semi-arid climate. Three scenarios were analyzed at a micro-basin level to determine the mitigation of surface runoff and the volume that can be theoretically intercepted for further use: (a) unaltered natural watershed (scenario 1), (b) currently urbanized watershed (scenario 2), and (c) watershed adapted with resilient strategies (scenario 3). For this last scenario, the annual usable volume of rainwater intercepted on the dwelling rooftops was obtained. The runoff and peak flow in the natural watershed were lower than in the other two scenarios. In contrast, a decrease in the runoff was observed in scenario 3 concerning scenario 2, which indicates that the interception of rainwater on house roofs and the adoption of green infrastructure solutions would significantly reduce the diameter of urban drainage pipes required in new developments, as well as the dependency of inhabitants on potable water services. In sites with semi-arid climates, it is possible to take advantage of the rainwater harvested on rooftops and the runoff intercepted through green infrastructure to mitigate local water scarcity problems, which should be considered and adopted in new residential developments.

“…Más de una tercera parte de la población mundial carece de instalaciones hidráulicas adecuadas (onu, 2019), mientras que un quinto de la población sufre cortes de agua persistentes desde hace más de dos décadas (undp, 2006). Estos problemas ocurren, entre otras cosas, por el rápido crecimiento de las ciudades, que normalmente exceden la capacidad de las autoridades locales para implementar medidas adecuadas (Mahaut y Andrieu, 2019). Sumado a esto, la falta de estrategias y políticas de planeación urbana adecuadas ha ocasionado problemas relacionados con el agua, tales como desastres por inundaciones, así como escasez y cortes de agua, entre otros (Nguyen et al, 2019).…”

Pachuca de Soto satisface sólo el 45% de la dotación diaria para consumo doméstico. Se proponen medidas de conservación: reusar el agua gris recuperable y cosechar el agua de lluvia en la azotea de una vivienda de interés social para reducir la necesidad de agua limpia para fines no potables. Se cuantificaron los volúmenes de agua potable necesarios (167.7 L/h/d), de agua gris reusable (73 L/h/d) y de agua residual (53.4 L/h/d). Se determinó la precipitación promedio diaria (hpd=1.28 mm) para un año, a partir de un registro histórico de 1991-2014. Se estimó el volumen de agua de lluvia con hpd, la superficie de azotea disponible (75 m2) y un coeficiente de escurrimiento para superficies de concreto (0.8). Se determinó la huella de escasez hídrica total (HEH), sumando la huella de escasez hídrica directa (HEHD) e indirecta (HEHI). Se utilizó un indicador regional de disponibilidad de agua (AWARE Annual agri); las entradas directas (consumo de agua potable antes y después de utilizar las medidas de conservación), así como la entrada indirecta (agua consumida en la operación de una bomba de ¾ Hp). La HEH se redujo de 4.83 a 1.91 m3 equivalentes, particularmente a través de la HEHD.
