  1. Advances in hydraulic fracturing (aka “fracking”) technologies and horizontal drilling have enabled the extraction of previously unviable unconventional oil and gas resources. However, as global environmental concerns have become more prominent and unconventional oil and gas developments have moved ever closer to residential centers, public scrutiny of the industry and its methods and impacts of extraction have increased. Water impacts feature prominently among the contemporary societal concerns about fracking. These concerns include the large water requirements of the process itself, as well as concerns about the potential pollution of groundwater and the (underground) environment more broadly. Anthropologists have undertaken qualitative field research on unconventional gas developments in a variety of settings, largely among local communities in regions of extraction. The perspectives employed by anthropologists are commonly drawn from the broader social science literature, including the anthropology of water and natural resources, science and technology studies, studies of social movements, and studies which examine the energy‐society nexus. Based on the shortcomings of the published anthropological accounts, interdisciplinary research collaboration with hydrologists, engineers and economists, as well as a more fulsome engagement with the variety of hopes, fears and dreams of fracking and unconventional gas, is recommended.WIREs Water2018, 5:e1272. doi: 10.1002/wat2.1272 This article is categorized under:Engineering Water > Sustainable Engineering of WaterScience of Water > Water QualityHuman Water > Methods

  2. Private households around the world use and combine multiple water sources, including diverse forms of market services and self-supply. The reasons for this have so far not been explained in a coherent framework, nor have the implications for water management and policy been sufficiently analyzed. Here, we examine how heterogeneity of water services, household co-production, and risks of provision influence household demand patterns. We apply an economic household production model that incorporates two water quality levels for different household activities to exemplary situations. We derive a number of explanations why households use and combine water services that expand the current state of research. Relevant findings include: (i) The diverse characteristics of available water services result in different time requirements for water procurement and varying degrees of suitability for household activities. (ii) Differences in the value placed on time can induce households to demand heterogeneous water services because these enable them to find a balance between using time and money to access water. (iii) Certain water services may be demanded because they function as insurance against both uncertain and unreliable supply. Our insights are relevant for water policy, in particular for developing and managing demand-responsive systems, and for the implementation and monitoring of normative goals for access to water.
