“…Urbanization is characterized by population aggregation, land use and land cover change-especially the expansion of built-up spaces-and intensive, localized economic development, all of which have significant impact on water resources and the broader water environment [12,[19][20][21][22]. In turn, the degradation of water resources encumbers socioeconomic development, for instance through higher costs of water use and sewage treatment, higher incidence of infectious diseases such as cholera and dysentery, and adverse public opinions arising from water pollution and other unpleasant aspects of a degraded environment.…”

The Water-Economy Nexus and Sustainable Transition of the Pearl River Delta, China (1999–2015)

As the world’s largest urban area in both size and population, the rapid development of the Pearl River Delta (PRD) during past three decades has been accompanied by worsening water problems. This paper examines the water-economy nexus of the PRD from the perspectives of both water use and water quality between 1999 and 2015, with a Logarithmic Mean Divisia Index decomposition model as well as an Environmental Kuznets Curve model, in order to assess the sustainable transition of the area. The results show that in this period, while the water dependency of economic development went down by a significant extent, the efficiency gains did not prevail over problems caused by economic scale expansion. However, at the city level, the 2008 financial crisis stimulated an economic transformation of the main economies from being scale-dominated to being efficiency-dominated. From 2009 to 2015, the sewage decreases driven by water dependency of Guangzhou, Shenzhen, and Dongguan outweighed the sewage increases driven by economic scale. While sewage discharge increased, the river water quality of the PRD kept improving. We found an inverted “U”-shaped relationship between GDP per capita and water quality of the PRD, with GDP per capita = ¥14,228.27 as the inflection point for river water quality. Once dubbed the “factory floor” of the world, the PRD has moved into a less environmentally impactful phase of development, with more expenditure on environmental protection and policy reform. However, given the huge and ever-increasing economic and population scales, ensuring a sufficient and safe water supply through industrial recycling and public education, along with even further pollution abatement, will be particularly important.

“…The upper watershed is undergoing rapid transition from forest to urban/developed land. The changes in land use distribution are expected to bring changes in water quality, including surface flow, nutrient runoff, and sedimentation levels (Bhattarai et al 2008). For land use change scenarios, we used land use shapefiles downloaded from AlabamaView website (AlabamaView 2009) for the SCW for 1991.…”

In this study, a watershed model WARMF (Watershed Analysis Risk Management Framework) was applied to the Saugahatchee Creek Watershed in Alabama to investigate hydrologic and water quality response to historical land use scenarios and potential future climate change scenarios. Based on monthly average of daily predicted values, land use changes from 1991 to 2008 led to rising pattern in nutrient levels and algal mass depleting water quality in the Saugahatchee Creek. Future climate projections for the 21 st century derived from HadCM3 A2 and B2 emission scenarios were downscaled using Statistical DownScaling Model (SDSM) to local watershed scale for impact analysis. The monthly average of daily water temperature is predicted to rise and flow is predicted to decrease with warmer and drier future climate projections. Accordingly, nutrient concentrations are expected to increase. Algal concentration is predicted to increase up to mid-21 st century and then decline thereafter. Dissolved oxygen concentration is predicted to fall, especially in summer. These results under different land use and climate change scenarios can be useful information for watershed planning and management decision.

“…Unlike surface waters, underground waters are not always suitable for irrigation, their salt content and composition depends upon the location and geo-climatic factors. The water quality in watershed is directly affected by vegetative cover and agricultural and other land management practices (Bhattaria et al 2008). …”

Use of irrigation water available from various sources in agriculture is justified on agronomic and economic grounds but care must be taken to minimize its adverse environmental and health impacts. During the study 44 water samples, available from the various resources viz., canal, sewage pipe line, tube wells in confined aquifers, tube wells in unconfined aquifers, and wells in the Chaka block district Allahabad, were chemically analyzed to check its suitability for irrigation and to classify it according to amount of salts present. The analysis reveals that most of the samples were within the lower alkalinity limit (pH 7.17-8.42), except sewage water (pH 7.34-9.04). The electrical conductivity of the samples ranged from 0.26 to 1.37 millimhos/cm. Potassium, sodium, calcium, and phosphorus are all found to be in permissible range except one sample in the village Kuria in which Na percentage was found in doubtful category. The other parameters like sodium adsorption ratio, SAR (1.17-2.74), residual sodium carbonate, RSC (-4.46 to -1.07), and soluble sodium percentage, SSP (63.97-28.15) were also found below the permissible limit.
