“…With the gradual decrease in the block width, the recommendation of the number of new monitoring wells increase. The incorporation of the relatively influential role of block width for interpolation has not been documented in previous studies based on geostatistical methods [13,16]. Hence, this study has pioneered the incorporation of this factor in the monitoring network optimization process.…”

The aim of this work is to investigate new approaches using methods based on statistics and geo-statistics for spatio-temporal optimization of groundwater monitoring networks. The formulated and integrated methods were tested with the groundwater quality data set of Bitterfeld/Wolfen, Germany. Spatially, the monitoring network was optimized using geo-statistical methods. Temporal optimization of the monitoring network was carried out using Sen's method (1968). For geostatistical network optimization, a geostatistical spatio-temporal algorithm was used to identify redundant wells in 2-and 2.5-D Quaternary and Tertiary aquifers. Influences of interpolation block width, dimension, contaminant association, groundwater flow direction and aquifer homogeneity on statistical and geostatistical methods for monitoring network optimization were analysed. The integrated approach shows 37% and 28% redundancies in the monitoring network in Quaternary aquifer and Tertiary aquifer respectively. The geostatistical method also recommends 41 and 22 new monitoring wells in the Quaternary and Tertiary aquifers respectively. In temporal optimization, an overall optimized sampling interval was recommended in terms of lower quartile (238 days), median quartile (317 days) and upper quartile (401 days) in the research area of Bitterfeld/Wolfen. Demonstrated methods for improving groundwater monitoring network can be used in real monitoring network optimization with due consideration given to influencing factors.

“…The last three decades has achieved great improvement in groundwater monitoring strategies, the majority of which have strongly focused on statistical approach for monitoring locations and sample size [11][12][13]. However, relatively little work is in place with optimization considering multiple contaminants in multiple aquifers.…”

“…The institutional approach to managing groundwater by arresting the over-exploitation of groundwater and by mitigating environmental consequences is through the implementation of a systematic groundwater monitoring program [8]. However, due to the high cost of supervision, groundwater exploitation has not been effectively monitored.…”

Groundwater depletion caused by agricultural irrigation is a worldwide problem. Digital technology has the potential to mitigate the groundwater over-exploitation problem by precisely restricting agriculture groundwater withdrawal and borewell construction. This study estimates how farmers respond to a pilot on digital groundwater supervision, which was implemented by the county government to limit the number and clarify property rights of irrigation borewells. By utilizing this recent pilot in rural China, we assess the causal impact of the digital groundwater supervision pilot on farmers’ water-saving irrigation (WSI) behaviors and investigate the heterogeneity effects and mechanisms related to the policy contents. A difference-in-differences (DID) strategy is applied to address the treatment effect of the digital groundwater supervision pilot. The results, which were based on a unique plot-crop-level panel dataset, indicate that farmers reduced water use after the pilot implementation, with most of the responses created through introducing water-saving technology and reducing water use intensity rather than through reducing irrigated acreage. In addition, village supervision, information, and cooperative incentives positively encourage farmers to adopt WSI technologies.

A Summary on the Special Issue “Sustainability of Groundwater”

One of the most common denominators for almost any form of life is the existential need for water. This need has recently received much attention in the frame of sustainability discussions [1,2]. In addition, environmental sustainability and safe access to fresh water is one of the eight United Nation's millennium development goals, and ultimately most conditions of life rely on water. Expected higher water demands for irrigation, industrial and household purposes outline the need for more investment in freshwater characterization and quantification. In addition, factors including climate change, large-scale reservoirs, re-channelling of streams, expansion of urban centres as well as chemical and microbial loading need to be taken into account.Within this framework groundwater plays an important role, because it is a compartment that has received little attention due to its hidden nature. This is particularly important for continental groundwater that is estimated to make up between only 0.3 and 1.6% of the global water budget [3]. From this small proportion, only a fraction is useable due to high salinity of mostly deeper groundwater. Nonetheless, groundwater is by far the most mined resource worldwide and is used in irrigation, industry and households [4,5]. For instance, Foster and Chilton [6] evaluated that groundwater globally provides 50% of drinking water, 40% of industrial water and 20% of the water used for irrigation. Other figures produced by the United Nations Environment Programme [7] indicate that today more than 25% of the world population (i.e. 1.5 to 2 billion people) rely on groundwater with expected future rapid growth. This growth in demand is partially due to better technologies that OPEN ACCESS
