It is a well-known fact that sustainable development goals are difficult to achieve without a proper water resources management strategy. This study tries to implement some state-of-the-art statistical and data mining models i.e., weights-of-evidence (WoE), boosted regression trees (BRT), and classification and regression tree (CART) to identify suitable areas for artificial recharge through floodwater spreading (FWS). At first, suitable areas for the FWS project were identified in a basin in north-eastern Iran based on the national guidelines and a literature survey. Using the same methodology, an identical number of FWS unsuitable areas were also determined. Afterward, a set of different FWS conditioning factors were selected for modeling FWS suitability. The models were applied using 70% of the suitable and unsuitable locations and validated with the rest of the input data (i.e., 30%). Finally, a receiver operating characteristics (ROC) curve was plotted to compare the produced FWS suitability maps. The findings depicted acceptable performance of the BRT, CART, and WoE for FWS suitability mapping with an area under the ROC curves of 92, 87.5, and 81.6%, respectively. Among the considered variables, transmissivity, distance from rivers, aquifer thickness, and electrical conductivity were determined as the most important contributors in the modeling. FWS suitability maps produced by the proposed method in this study could be used as a guideline for water resource managers to control flood damage and obtain new sources of groundwater. This methodology could be easily replicated to produce FWS suitability maps in other regions with similar hydrogeological conditions.

“…Aunque su localización se reduce a pequeños sectores de Túnez, Argelia, Libia y Marruecos, se trata de una técnica específica que aparece en todas las clasificaciones y tipologías de técnicas de cosecha de agua (water harvesting) (Despois, 1955;El Amami, 1977;El Amami y Chaabouni, 1981;Prinz, 1999;Berndtsson, 1999;Oweis et al, 2001;Prinz y Malik, 2002;Oweis y Hachum, 2003y 2009Oweis et al, 2004;Rutherford, 2000;Omrani y Ouessar, 2008;Ouessar et al, 2012;Jebari et al, 2015;Berndtsson et al, 2016;Yazar y Ali, 2016;Ben Salem et al, 2020).…”

El meskat es un sistema de cosecha de agua (water harvesting) muy extendido en la región del Sahel de Túnez. Como otros sistemas de zonas semiáridas, busca incrementar la cantidad de agua disponible para los cultivos, mediante sectores de producción de escorrentía (impluvium) y sectores de distribución del agua para riego esporádico (mankaa). Pero, a menudo, en un ambiente mediterráneo las precipitaciones presentan un carácter torrencial: son a la vez un recurso hídrico y un riesgo de erosión. Por ello, estos sistemas tienen que adaptarse a las condiciones climáticas, topográficas y litológicas locales. En el caso del meskat son diseños “a medida”, con un frágil equilibrio entre el máximo aprovechamiento del recurso hídrico y el mínimo riesgo de erosión.Este trabajo se aborda mediante técnicas de análisis espacial con SIG, una contextualización ambiental, sobre todo geomórfica, y una cuantificación de sus características topográficas básicas (altitudes, desniveles y pendientes). Para ello se ha realizado una cartografía detallada de sistemas, y una cuantificación topográfica y de usos del suelo a partir de un muestreo aleatorio de puntos. Con ello, se ha cuantificado el grado de presencia y la ratio producción/riego. Se pretende reconocer la existencia de tipologías de diseños y sus características más relevantes.Se trata de sistemas con soluciones adaptadas al medio, con una amplia variabilidad, pero con tipologías reconocibles, básicamente sistemas ubicados en vaguada y en glacis. A la vez, es un tipo de sistema con una rápida y reciente transformación, tanto de los propios usos del suelo como de los mismos cultivos.

“…The agricultural fields in the Mediterranean region are continuously expanding (Hervieu et al, 2008), with 85% of them rated as ‘high consumption fields’ in terms of water use, while most are less than 50% production efficient, especially in the southern MBR. The majority of developing countries still following traditional flooding systems have poor irrigation management practices (Berndtsson et al, 2016; Voltz et al, 2018). In the coming decades, the situation is expected to worsen within the region, because arable land is scarce and the regional water balance is changing.…”

The ever-increasing water demands in the agricultural sector of the Mediterranean basin region (MBR) under climate change warrants that crop water productivity (WP) is a pertinent topic for discussion. Considering this need, this study aims to synthesize the body of knowledge on WP focusing on the MBR.The study is based on two test cases: (1) wheat, because it is a basic staple food in high dietary demand in the region and (2) barley, because it is a climateresilient alternative that is extensively cultivated in severe water-and salinitystress conditions. These staple crops are strategically important for regional food security in the MBR, which covers southern Europe, North Africa and western Asia. The study tries to investigate the plausible reasons for yield and WP gaps in the region. Our meta-analysis revealed that wheat and barley are very different in their spatial distributions, productions and stress resiliencies in the MBR. Under the large gamut of biophysical and socio-economic con-
