Worldwide groundwater reserves are increasingly exploited to support escalating water demands resulting from population and economic growth. Groundwater over-extraction causes not only aquifer depletion and pollution but also aquifer-system compaction, leading to land subsidence. This issue is of particular importance in densely populated and econo...

Groundwater abstraction of various magnitudes, pumped out from numerous depths in a multitude of layers of aquifers, stimulates different changes in hydraulic head distribution, including ones under vertical cross-sections. This generates groundwater flow in the vertical direction, where groundwater flows within its storage from the shallow to the...

Sand mining in southern Africa is on the rise, fuelled largely by rapid urbanisation. This creates a range of societal and biophysical challenges and supports livelihoods in regions with high unemployment. Relevant scientific studies are scarce. This study explores the impacts of sand mining from ephemeral rivers on Botswana, South Africa and Mozam...

The Limpopo River Basin (LRB) is highly vulnerable to recurrent floods and droughts, which significantly threaten its water and food security.

A transboundary b...

Due to technical, social, and economic limitations, integrated groundwater management presents a significant challenge in developing countries. The significance of this issue becomes even more pronounced in groundwater management, as this resource is often overlooked and undervalued by decision-makers due to its status as a “hidden resource,” despi...

In the present study, we review the methods and approaches used for uncertainty handling in hydrological forecasting of streamflow, floods, and snow.

Groundwater plays a vital role in human consumption and irrigation in many parts of Bolivia; yet, the absence of policies to regulate its extraction and protect groundwater recharge areas has led to a decline in water tables and threatened food security. Some municipal initiatives have been implemented to develop regulations, but the lack of reliab...

Groundwater recharge is affected by various anthropogenic activities, land use and land cover (LULC) change among these. The long-term temporal and seasonal changes in LULC have a substantial influence on groundwater flow dynamics. Therefore, assessment of the impacts of LULC changes on recharge is necessary for the sustainable management of ground...

Globally, the hydro-climatological parameters such as precipitation, temperature, and soil moisture are getting more uncertain and varying regionally as well as seasonally with the changing climate. The Nordic region and the regional agriculture are no exception to this. Recent global studies have projected the increasing trend of precipitation...

Irrigation is vital in Bangladesh in order to meet the growing food demand as a result of the increasing population. During the dry season, groundwater irrigation is the main source of water for agriculture. However, excessive abstraction of groundwater for irrigation causes groundwater level depletion. At the same time, the loss from excessive irr...

Water excess and shortage (drought) are becoming more frequent phenomena that challenge the development of agriculture and crop production in Nordic countries. Indeed, water excess has been traditionally the main cause for crop failure in Nordic agriculture, and waterlogging causes substantial yield losses in this region (Bertholdsson, 2013; Sundgr...
