Abstract. Global trends suggest that cities around the world are increasingly depleting available water resources. A common strategy is to opt for supply augmentation infrastructure. However, this response can be a financial and social burden for many cities, because they entail developing expensive infrastructure and can trigger social conflicts....

... the 1980s, water managers in Jalisco were aware of the relentless growth of Guadalajara and sought to develop new sources of water besides groundwater and Lake Chapala (Flores Berrones, 1987). They analyzed that the only nearby region with enough water to supply Guadalajara was the Verde River basin, located in the north of Jalisco (Figure 1). They calculated a potential of more than 20 m 3 /s, enough to supply water for Guadalajara for the coming decades with its expected urban growth and future water demand. ...

... most aquifers present serious water balance 300 deficits, which jointly amount to more than 150 hm 3 /year in Los Altos' aquifers (CEA Jalisco, 2018); and many have presence of fluoride and arsenic (Hurtado-Jimenez & Gardea-Torresdey, 2005, 2006).As agricultural outputs keep increasing around 9%/year (Ochoa- ), groundwater overexploitation may exacerbate the future water demand. Although there are no clear numbers on the water balance for surface and groundwater separately, water authorities calculated a combined renewable water availability in the Verde River basin, which also includes groundwater in Aguascalientes (Figure 1), of 1,624 305 hm 3 /year, while water demand was 1,804 hm 3 /year (Conagua-Semarnat, 2012). ...

... station has measured an average flow of 599 hm 3 /year (IMTA, 2015), which is enough to fill the Zapotillo dam in one year at a height of 80 m, or two years at a height of 105 m. Currently that water flows directly to the Santiago River (see Figure 1). Farmer representatives in Los Altos have stated that, if indeed these claimed surface water resources of the Verde River exist, they should be used to contribute to the potential growth of Los Altos. ...

Droughts exert widespread impacts on both natural and social systems, and there is accumulating evidence that this situation may worsen in the context of global warming. Despite the importance of assessing changes in droughts to understand their potential future impacts on society, studies are unevenly distributed worldwide. In this study, utilizin...

... Some of the unintended consequences of these measures is the worsening conditions of large sections of the population once the private water utility takes over (Bakker 2013: 215). This approach brings back the political dimension of water security, when other approaches intend to depoliticize agendas that include large grey infrastructure as a vital component of water security without considering alternatives to large grey infrastructure nor the uneven distribution of costs and benefits of large grey infrastructure across different sectors of society and natural systems (Boelens and Seemann 2014;Godinez-Madrigal et al. 2020). The focus of this book is to compare such grey infrastructures to smaller green intervention measures and the protective function of green infrastructure functions and its services. ...
... The 'levee effect' emerges when levees are built to protect societies from flooding, but in turn diminishes social memory over larger periods of time by giving a sense of unfounded sense of security that can backfire with an extreme hydro-climatic event (Di Baldassarre et al. 2013). In the social sciences, recent research shows that large infrastructure can trigger intractable social conflicts that forestalls the development of any kind of solution, while urban water systems continue to deplete groundwater with increasing socio-ecological costs (Godinez-Madrigal et al. 2020). ...
This chapter provides the context of water security for ecosystem-based approaches, notably nature-based solutions (NBS) operationalized in natural assurance schemes (NAS). The huge potential and value of nature-based solutions to both mitigate the effect of water while providing large and important co-benefits is addressed in this book and for this a deeper understanding is needed on how this contributes to water security and how barriers to implementation of NBS and NAS can be overcome. Firstly, relevant concepts and approaches of water security are introduced and reviewed; secondly, the assurance and insurance value is elaborated upon as distinct properties of ecosystem-based approaches; thirdly, the concepts of readiness levels for technology and knowledge, socio-institutionality and investment are introduced to address barriers for the operationalization of the value of ecosystem-based schemes to develop and harvest the full potential of climate resilient investments while addressing EU policies, including the Green Deal, Climate Adaptation Strategy and Strategy for Biodiversity. Finally, based on this chapter, overarching questions are posed which are addressed and discussed in the course of this book.
