Insights and participatory actions driven by a socio-hydrogeological approach for groundwater management: the Grombalia Basin case study (Tunisia)

Abstract

Sustainable groundwater management in water-scarce countries is a pragmatic example of the necessity to guide future decision-making processes by simultaneously considering local needs, environmental problems and economic development. For these reasons the new socio-hydrogeological approach, Bir Al-Nas, proposed by Re (2015), has been tested in the Grombalia region (Cap Bon Peninsula, Tunisia), to evaluate the effectiveness of `complementing hydrogeochemical and hydrogeological investigations by considering the social dimension of the issue at stake. Within this approach the social appraisal, performed through Social Network Analysis and public engagement of water endusers, allowed hydrogeologists to get acquainted with the institutional dimension of local groundwater management, identifying issues, potential gaps, such as weak knowledge transfer among concerned stakeholders, and the key actors likely to support the implementation of new science-based management practices resulting from the ongoing hydrogeological investigation. Results hence go beyond the specific relevance for the Grombaila basin, showing the effectiveness of the proposed approach and the importance to include social 2 assessment in any given hydrogeological research aimed at supporting local development through groundwater protection measures.

EU Nitrates Directive, from theory to practice: Environmental effectiveness and influence of regional governance on its performance

“…Although social network analysis was shown to be an effective method for these aims, its application is quite a novelty in hydrogeological assessments. To our knowledge it was only used in two studies that explicitly focused on groundwater governance, both of which were carried out in rural developing regions (Kuzdas et al 2015;Tringali et al 2017).…”

Integrated socio-hydrogeological approach to tackle nitrate contamination in groundwater resources. The case of Grombalia Basin (Tunisia)

“…Therefore, during the previously described field work performed, all the farmers and well owners of the 51 sampled sites were asked to respond to structured interviews on water use and agricultural practices (Tringali et al, 2017). The main goal of this activity was to create a momentum for dialogue on local groundwater protection and capacity building, while also collecting relevant information on groundwater use and pollution issues.…”

Quantifying irrigation adaptation strategies in response to stakeholder-driven groundwater management in the US High Plains Aquifer

“…California's recent Sustainable Groundwater Management Act (Kiparsky 2016)), and the world (e.g. Tringali et al 2017). Here, we analyzed the effects of this first LEMA on groundwater pumping, water levels, and irrigated crop dynamics to address two main questions: (1) How did the observed pumping volumes following LEMA establishment differ from the pumping that would have occurred in its absence, controlling for climate and evolving management trends?…”
