“…The evaluation methods of WRCC include the empirical formula method, the comprehensive evaluation method, the system analysis method, and quota water consumption [21][22][23][24][25]. The calculation of WRCC mainly involves quantitatively measuring the levels of economic and population development that regional water resources can support [27,28].…”

Evaluation of Agricultural Water Resources Carrying Capacity and Its Influencing Factors: A Case Study of Townships in the Arid Region of Northwest China

The water resources carrying capacity (WRCC) strongly determines the agricultural development in arid areas. Evaluation of WRCC is important in balancing the availability of water resources with society’s economic and environmental demands. Given the demand for sustainable utilization of agricultural water resources, we combine the water stress index and comprehensive index of WRCC and use multi-source data to evaluate agricultural WRCC and its influencing factors at the township scale. It makes up for the deficiencies of current research, such as the existence of single-index evaluation systems, limited calibration data, and a lack of a sub-watershed (i.e., township) scale. By applying multi-source data, this study expands the spatial scale of WRCC assessment and establishes a multidimensional evaluation framework for the water resources in dryland agriculture. The results indicate water stress index ranges from 0.52 to 1.67, and the comprehensive index of WRCC ranges from 0.25 to 0.70, which are significantly different in different types of irrigation areas and townships. Water quantity and water management are key factors influencing WRCC, the water ecosystem is an area requiring improvement, and the water environment is not a current constraint. Different irrigation areas and different types of townships should implement targeted measures to improve WRCC.

Toxic elemental exposure through consumption of contaminated crops is becoming a serious concern for human health. Present study is based on the environment and health risk assessment of wastewater irrigated soil and crops in a semi-arid region Faisalabad, Pakistan. The concentrations of potentially toxic elements (Cu, Cr, Mn, Fe, Pb, Zn, Ni) were analysed by atomic absorption spectrometer in five different crops (Corn, rice, wheat, sugarcane and millet), while, their topsoil’s and multi targeted risks analysis were assessed. Results showed, the mean values of Pb and Zn were higher in crop than Food and Agriculture Organization guidelines for food additives and contaminants. A strong positive correlation was found among wastewater and crop’s toxic metals (r 2 values in Cu, Zn, Pb, Ni and Cr were 0.913, 0.804, 0.752, 0.694, 0.587 respectively). Whereas, a strong correlation was also found among soil and wastewater lead (r 2 = 0.639). The calculations of Nemerow Integrated Pollution Index (NIPI) showed the soil samples maximum pollution limit (NIPI > 3) and Potential Ecological Risk Index (PERI) was found to be higher than maximum limit (PERI > 600) for all samples. While, for non-carcinogenic risk, Hazard Index (HI) values in adult were near threshold (HI > 1) for all crop samples. In children, the HI values for Corn, Rice and Wheat were above threshold limit and for Sugarcane and Millet, these were near to threshold. Cancer risk values for Cr found higher than safe limit (1 × 10 –6 ) in adult and children for crop samples. Crop irrigation by wastewater irrigation is a prominent alternative option for water scarce countries, however prior testing and treatment of such wastewater streams must be employed to minimize the adverse impacts on human health and environment.

“…Well-being and the health of citizens are closely related to the level of access to water and sanitation (Hutton & Chase, 2016;Naimi-Ait-Aoudia & Berezowska-Azzag, 2014). Consequently, the decisions taken by stakeholders to guarantee the quality and quantity of water resources, and the water supplied and used have an influence on the key issues quantity of water, water quality, use of water and water supply, which are analyzed in urban water throughput (4.2), but also in water equity (4.3) and water resources (4.1).…”

About 56 percent of the world’s population currently lives in cities. Anthropogenic activities have both directly and indirectly modified their environment. Therefore, management actions at the urban level determine whether or not cities are heading toward sustainability. Consequently, water management is in need of a clear insight of the social and ecological water-related interactions. Thus, a new operational approach is proposed for a better understanding of the interactions between the water cycle, cities and the society. In our approach, eleven key issues and their interactions emerge from an analysis of 371 documents published between 2012 and 2018. The interactions between different key issues were examined through four main foci of analysis: water resources, urban throughput, water equity, and water governance and financing. Those main foci help to comprehend water as a holistic element intertwined in urban areas. In addition, our approach provides six challenges to guide the stakeholders in decision-making processes: how to recognize, integrate, and/or restore water-related ecosystem services, how to maintain and improve the supporting green and blue spaces, how to guarantee the quality and quantity of water resources and the water supplied and used, how to ensure public and social health and well-being of the citizens, how to prevent and manage water-related conflicts, and how to make informed and equitable decisions on water management at urban level?
