Many papers, including a recent editorial of this journal Stakhiv 2003 , have advocated the need for paradigm shift toward adaptive, integrated water resources management as means to attain rationalization in use. There is, however, one significant element policy that has received less attention by most experts and decision-makers: intensive groundwater use irrigation arid semiarid regions more significantly developing countries . This provides an overview phenomenon its main pros cons,...

Water resource management is often a controversial issue in semiarid regions. Most water resources experts admit that conflicts are not caused by the physical scarcity but they mainly due to inadequate management. The virtual concept (the volume of used production commodity, good or service) together with footprint (indicator consumption looks at both direct and indirect use consumer producer), links large range sectors issues, thus providing potentially appropriate framework support more...

Halving the number of people without sustainable access to safe drinking water was a core target Millennium Development Goals. This led an unprecedented effort in sector, improving livelihoods millions people. While goal has officially been accomplished, unsuitable benchmarks have overstatement results. Indicators overemphasize improved sources, disregarding fact that many continue be contaminated, unreliable or unaffordable. The alleged success needs reframed avoid confusion, prevent...

Abstract. Groundwater is crucial for domestic supplies in the Sahel, where strategic importance of aquifers will increase coming years due to climate change. potential mapping a valuable tool underpin water management region and, hence, improve drinking access. This paper presents machine learning method map groundwater potential. illustrated through its application two administrative regions Mali. A set explanatory variables presence developed first. Scaling methods (standardization,...

Identifying groundwater-dependent ecosystems is the first step towards their protection.This paper presents a machine learning approach that maps by extrapolating from characteristics of small sample known wetland and non-wetland areas to find other with similar geological, hydrological biotic markers.Explanatory variables for occurrence include topographic elevation, lithology, vegetation vigor, slope-related variables, among others.Supervised classification algorithms are trained based on...

Abstract Conflicts between intensive groundwater use and wetland conservation are widespread throughout arid semiarid regions worldwide. These have become more significant wherever there has been a synchronism pumping‐based human development the awakening of an environmental awareness in society. The Mancha Occidental aquifer provides example such occurrence, which given rise to noteworthy social conflicts. This paper presents cross‐policy analysis for restoration measures, establishing main...

Abstract Groundwater resources are crucial to safe drinking supplies in sub‐Saharan Africa, and will be increasingly relied upon a context of climate change. The need better understand groundwater calls for innovative approaches make the best out existing information. A methodology map potential based on an ensemble machine learning classifiers is presented. large borehole database ( n = 1848) was integrated into Geographic Information Systems (GIS) environment used train, validate test 12...

This paper presents a machine learning method to map groundwater potential in crystalline domains. First, spatially-distributed set of explanatory variables for occurrence is compiled into geographic information system. Twenty classifiers are subsequently trained on sample 488 boreholes and excavated wells region eastern Chad. process includes collinearity, cross-validation, feature elimination parameter fitting routines. Random forest extra trees outperformed other algorithms (test score >...

Groundwater provides a strategic resource in the face of uncertain climate conditions arid and semi-arid regions. Solar-based groundwater pumping is quickly gaining ground across rural sub-Saharan Africa, promoted by national international organizations as new technology choice for water supply irrigation. A crucial question large-scale developments whether pre-existing boreholes can be fitted with solar pumps. Based on data from southern Madagascar, this paper an automated method to deal...

Over the last decades, agriculture in arid and semi-arid countries has experienced a true "silent revolution" of intensive groundwater use. Millions independent farmers worldwide have chosen to become increasingly dependent on reliability resources, as result their reaped abundant social economic benefits. Data from several shows that irrigation presents much greater efficiency, than surface water systems, thus contributing fulfil motto "more crops jobs per drop". If this situation is...

Abstract This paper presents an approach to estimate the effects of a managed recharge experiment in multilayer aquifer characterized by presence perched water tables Medina del Campo groundwater body, Douro basin, central Spain. A numerical model was developed evaluate effect artificial on shallow sector regional‐scale and formerly active wetlands. The Visual MODFLOW Pro v.2011.1 environment order represent analyse regional impact this event. Results suggest that assumption single system...
