“…According to the model, an increase of intensity will augment the volume of runoffs, but recharge will not increase. This phenomenon has been previously predicted for the Santo Domingo aquifer, located 400km north of the study area [15].…”

“…One of the most popular groundwater models is MODFLOW, a cell-centered, 3D-finite difference model, which is recognized as a very useful tool for understanding regional groundwater systems, management of groundwater resources, and planning for future water consumption [14][15][16]; additionally, it has been demonstrated to be useful for the analysis of surface water bodies as lakes and lagoons [17][18][19][20].…”

In arid and semiarid zones, groundwater plays a key role in the ecology and availability of freshwater. Coastal lagoons in arid zones have great importance as a refuge for species of flora and fauna, as a source of freshwater, and for recreational purposes for local communities and tourism. In addition, as environments under natural stress, they are suffering pressure from anthropogenic activities and climate change, especially in zones with intense touristic development as in the case of the Baja California Peninsula in northwest Mexico. In this paper, we analyze the future of a coastal lagoon impacted by climate change and anthropogenic pressures. We constructed a groundwater MODFLOW-SWI2 model to predict changes in freshwater–saltwater inputs and correlated them with the geospatial analysis of the distribution and evolution of the water body and surrounding vegetation. The methodology was applied to the San Jose lagoon, one of the most important wetlands in the Baja California peninsula, which had been affected by anthropogenic activities and endangered by climate change. According to our water balance, the deficit of the San Jose aquifer will increase by 2040 as a result of climate change. The water table north of the lagoon will drop, affecting the amount of freshwater inflow. This reduction, together with an increase of evapotranspiration and the sea-level rise, will favor an increase of mineralization, reducing the surface water and groundwater quality and in consequence affecting the vegetation cover. Without proper management and adequate measures to mitigate these impacts, the lagoon may disappear as a freshwater ecosystem. Results of this research indicate that the use of a groundwater flow model, together with a geospatial analysis provide effective tools to predict scenarios for the future of coastal lagoons, and serve as a basis for land planning, nature conservation, and sustainable management of these ecosystems.

“…Third, I found that inter-sectoral water competitionnamely urban-industrial and environmental flows allocation (e.g., Rasul, 2014;Baleta & Winter, 2016;Shah & Zerriffi, 2017;Cetinkaya & Gunacti, 2018)was associated with water insecurity in 36.4% of publications (14.6% of listed causes). Water extraction and depletion appeared in 32.3% of the publications (12.6% of listed causes), and included increasing irrigation demand associated with water-intensive cultivation systems, such as rubber plantations (Chiarelli et al, 2017), groundwater extraction for transnational agri-businesses (e.g., Hidalgo et al, 2017), and the potential for extensive water-use to contribute to linked socio-hydrological challenges, such as groundwater salinization (Wurl et al, 2018).…”

How is water security conceptualized and practiced for rural livelihoods in the global South? A systematic scoping review

In the global South, rural and resource-based livelihoods increasingly face water-related risks. The conceptualization and application of the water security concept in relation to rural livelihoods has not been reviewed in this context. To fill this gap, a systematic scoping review of refereed journal articles (2000–2019) was conducted to examine how water security is defined, driven, and addressed for rural livelihoods in the global South. Publications (n = 99) featured diverse methodologies and geographical contexts, and recognized simultaneous drivers of water insecurity and solution strategies for water security. Several shortcomings were evident. First, only 30.3% of publications defined the concept, mostly using frames of ‘adequate’, ‘sufficient’, and ‘acceptable’ water-related risks. Few definitions recognized the role of water security interventions in increasing capabilities and prosperity. Second, technical and managerial responses to proximate drivers of water-related risk – namely climate-related dynamics, water re-allocation, extraction, and mismanagement – outnumbered efforts to identify and transform the underlying social, economic, and political inequities that create and sustain water insecurity. Last, studies focused heavily on agriculture, while labour, transhumance pastoralism, and aquaculture were underrepresented. A research agenda that increases the synergies between the wider water security and rural livelihoods scholarship is advanced to address these shortcomings.

“…La generación de modelos que simplifiquen el conocimiento científico es importante en la conceptualización de sistemas conectados entre sí, como lo plantea Wurl et al (2018), quienes presentan la hidrodinámica subterránea contra la extracción de agua de un acuífero, al tiempo que analizan la gestión intersectorial. Abordan el estudio desde una perspectiva socio-hidrológica cuya conceptualización facilita estrategias alternativas y plausibles en el logro de una coevolución en la actual forma de gestión del agua subterránea, donde la participación es un factor clave, ya que la adaptación ocurre a través de la forma en la que se construye la política pública.…”

A partir de un estudio interdisciplinario sobre la participación sociopolítica en la formulación del Programa de Ordenamiento Ecológico Local (POEL) de Bacalar, analizamos las motivaciones y dificultades para considerar la "vocación natural” de este territorio, es decir, la capacidad que tiene para sustentar las actividades de los diversos seres vivos que lo habitan, partiendo del hecho de que se trata de un sistema kárstico. Para incluir dicha consideración, el equipo de investigación implementó una estrategia de investigación-acción (IA) que consistió en elaborar un modelo de conectividad hidrogeológica y sumarse a las gestiones para la configuración de este instrumento de política pública. Desde un enfoque socioambiental, la investigación incluyó técnicas etnográficas como entrevistas, observación participante y diario de campo. Los resultados muestran que algunas de las representaciones territoriales de los actores son incompatibles con las características del sistema kárstico y plantean la necesidad de una política participativa, orientada a la construcción de una visión común del territorio mediante procesos de socialización del conocimiento entre los actores y los sectores involucrados. Entre las limitantes de la IA se encontró que, a pesar de lograr la convergencia de sectores, se mantuvo la dinámica inercial que hasta ahora ha impedido la entrada en vigor del POEL en un espacio cada vez más codiciado y en riesgo para el ecosistema y quienes lo habitan.
