Abstract

Sustainable groundwater management strategies in water-scarce countries need to guide future decision-making processes pragmatically, by simultaneously considering local needs, environmental problems and economic development. The socio-hydrogeological approach named ‘Bir Al-Nas’ has been tested in the Grombalia region (Cap Bon Peninsula, Tunisia), to evaluate the effectiveness of complementing hydrogeochemical and hydrogeological investigations with the social dimension of the issue at stake (which, in this case, is the identification of groundwater pollution sources). Within this approach, the social appraisal, performed through social network analysis and public engagement of water end-users, 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 the 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 of including social assessment in any given hydrogeological research aimed at supporting local development through groundwater protection measures.

Aperçus et actions participatives guidées par une approche socio-hydrogéologique pour la gestion des ressources en eau: le cas d’étude du bassin de Grombalia (Tunisie)

Résumé

Les futurs processus de prise de décision ont besoin d’être guidés par des stratégies de gestion durable des eaux souterraines dans les pays à faibles ressources en eau, en considérant simultanément les besoins locaux, les problèmes environnementaux et le développement économique. L’approche socio-hydrogéologique nommée « Bir Al-Nas » a été testée dans la région de Grombalia (Péninsule du cap Bon, Tunisie) afin d’évaluer l’efficacité de la complémentarité des études hydrogéologiques et hydrogéochimiques avec la dimension sociale de l’enjeu (qui, dans ce cas, est l’identification des sources de pollution des eaux souterraines). Dans le cadre de cette approche, l’évaluation sociale est effectuée par une analyse du réseau social et de l’engagement public des utilisateurs finaux de l’eau. Elle a permis aux hydrogéologues de connaître la dimension institutionnelle de la gestion locale des eaux souterraines, d’identifier les sujets à enjeux, les potentiels écarts (tels que les faiblesses de transfert de connaissance parmi les acteurs concernés) et les acteurs clés susceptibles de soutenir la mise en œuvre de nouvelles pratiques de gestion fondées scientifiquement et résultant des études hydrogéologiques en cours. Les résultats vont par conséquent au-delà de la pertinence spécifique pour le bassin de Grombalia. Ils montrent l’efficacité de l’approche proposée et l’importance d’inclure l’évaluation sociale dans toute recherche hydrogéologique ayant pour objectif de soutenir le développement local par des mesures de protection des eaux souterraines.

Perspectivas y acciones participativas impulsadas por un enfoque socio-hidrogeológico para la gestión del agua subterránea: estudio de caso de la Cuenca de Grombalia (Túnez)

Resumen

Las estrategias de gestión sostenible del agua subterránea en los países con escasez de agua deben orientar los procesos de toma de decisiones en el futuro de forma pragmática, considerando simultáneamente las necesidades locales, los problemas ambientales y el desarrollo económico. En la región de Grombalia (Península de Cap Bon, Túnez) se ha puesto a prueba el enfoque socio-hidrogeológico denominado ‘Bir Al-Nas’, para evaluar la eficacia de complementar las investigaciones hidrogeoquímicas e hidrogeológicas con la dimensión social de la cuestión de interés (en este caso, es la identificación de las fuentes de contaminación del agua subterránea). Dentro de este enfoque, la evaluación social, realizada a través del análisis de la red social y el compromiso público de los usuarios finales del agua, permitió a los hidrogeólogos familiarizarse con la dimensión institucional de la gestión local del agua subterránea, identificando problemas, brechas potenciales (como una débil transferencia de conocimiento entre las partes interesadas) y los actores clave que probablemente apoyen la implementación de las nuevas prácticas científicas de manejo basadas en los resultados de la investigación hidrogeológica en curso. Los resultados, por lo tanto, van más allá de la relevancia específica para la cuenca de Grombaila, mostrando la efectividad del enfoque propuesto y la importancia de incluir a la evaluación social en cualquier investigación hidrogeológica destinada a apoyar el desarrollo local a través de medidas de protección del agua subterránea.

地下水管理中一个社会-水文地质方法带动的深刻认识和参与性行动:(突尼斯)古兰巴利耶流域研究实例

摘要

缺水国家的可持续地下水管理策略需要同时考虑当地需求、环境问题和经济发展来指引未来决策过程。在古兰巴利耶地区试验了被称为“Bir Al-Nas”的社会-水文地质方法,以评估在社会问题(在本研究案例中,问题就是地下水污染源的确定)岌岌可危的情况下补充水文化学调查和水文地质调查的有效性。在这个方法中,通过社会网络分析进行的社会评估及水最终用户的公共参与可以使水文地质工作者认识当地地下水管理的组织层面、需确定的问题、潜在的差距(如相关的利害关系人)及关键的活动者有可能支持在进行的水文地质调查中实施基于新科学的管理实践。因此,结果超出了古兰巴利耶流域特定的相关性,显示出了所提出方法的有效性及在任何旨在通过地下水保护措施支持当地发展的特定水文地质研究中的重要性。

Indagini e azioni partecipative realizzate tramite un approccio socio-idrogeologico per la gestione delle risorse idriche sotterranee: il caso dell’acquifero di Grombalia (Tunisia)

Riassunto

Nei Paesi caratterizzati da problemi di scarsità idrica è necessario che le strategie di gestione sostenibile delle acque sotterranee influenzino i processi decisionali tenendo in considerazione, allo stesso tempo, i bisogni locali, i problemi ambientali e lo sviluppo economico. L’approccio socio-idrogeologico ‘Bir Al-Nas’ è stato testato nella regione di Grombalia (Penisola di Cap Bon, Tunisia) con il fine di determinare se sia utile integrare le indagini idrogeochimiche e idrogeologiche con la dimensione sociale relativa all’oggetto di studio (nella fattispecie l’identificazione delle fonti inquinanti delle acque sotterranee). Tramite tale approccio, lo studio della dimensione sociale, realizzato attraverso l’analisi delle reti sociali e l’attività di partecipazione pubblica degli utenti finali della risorsa idrica, ha permesso agli idrogeologi di familiarizzare con la sfera istituzionale relativa alla gestione locale delle acque sotterranee, identificandone le problematiche, le potenziali lacune (ad esempio il limitato scambio di informazioni tra gli stakeholder) e gli attori chiave, in modo da contribuire all’implementazione di nuove pratiche di gestione basate su analisi scientifiche derivanti da studi idrogeologici. I risultati, quindi, non riguardano solamente la situazione specifica del bacino di Grombalia ma dimostrano, in generale, l’efficacia dell’approccio proposto e di quanto sia importante includere la dimensione sociale in ogni ricerca idrogeologica al fine di contribuire allo sviluppo locale attraverso pratiche di tutela delle acque sotterranee.

Perspectivas e ações participativas conduzidas por uma abordagem socio-hidrogeológica para a gestão das águas subterrâneas: o estudo de caso da Bacia de Grombalia (Tunísia)

Resumo

As estratégias de gestão sustentável das águas subterrâneas em países com escassez de água precisam orientar os processos decisórios futuros de forma pragmática, considerando simultaneamente as necessidades locais, os problemas ambientais e o desenvolvimento econômico. A abordagem socio-hidrogeológica chamada ‘Bir Al-Nas’ foi testada na região de Grombalia (Península do Cabo Bon, Tunísia), para avaliar a eficácia da complementação das investigações hidrogeoquímicas e hidrogeológicas com a dimensão social da questão em jogo (que, neste caso, é a identificação das fontes de poluição das águas subterrâneas). Dentro desta abordagem, a avaliação social, realizada através da análise da rede social e do engajamento público dos usuários finais da água, permitiu aos hidrogeólogos conhecer a dimensão institucional da gestão da água subterrânea local, identificando questões, lacunas potenciais (como a fraca transferência de conhecimento entre as partes interessadas) e os principais intervenientes susceptíveis de apoiar a aplicação das novas práticas de gestão baseadas na ciência, resultantes da investigação hidrogeológica em curso. Os resultados, portanto, ultrapassam a relevância específica para a bacia de Grombaila, mostrando a eficácia da abordagem proposta e a importância de incluir a avaliação social em qualquer pesquisa hidrogeológica destinada a apoiar o desenvolvimento local através de medidas de proteção de águas subterrâneas.
