This study used trend, correlation, and wavelet analysis to characterize Lake Chad (LC) level fluctuations, river discharge, El Niño Southern Oscillation (ENSO), and precipitation regimes and their interrelationships. Linear correlation results indicate a negative association between ENSO and LC level, river discharge and precipitation. Trend analysis shows increasing precipitation in the Lake ...

As key economic, ecological and demographic trends converge to reshape Africa and its relationship with the outside world, a new politics is emerging in the twenty-first century around the water-food-energy nexus, which is central to the continent's relevance in the global economy. On the one hand, Malthusian anxieties are proliferating; pessimists link population growth and growing water scarc...

Overutilization of groundwater resources can put their quality under stress. It could be base on rapid declination in groundwater level leading to salt water intrusion in the coastal aquifers. The objective of this study was to map the vulnerability of salt water intrusion of the Urmia Lake, Iran to nearby coastal aquifer (Azarshahr) using GALDIT method. The GALDIT index based on six parameters...

Abstract Rapid population growth has led to increasing demand for water resources. Studies have shown that the application of new technologies can effectively influence and promote citizens save water. The smart sensors monitor household consumption feedback recorded data promptly, thereby influencing family members' water-saving attitudes behaviours. For widespread use future in households, it...

wetlands as water resources have a special place in the semi-arid plateau of iran and boundary determination is necessary for their effective conservation and conflict resolution among stakeholders that are dependent on these resources. determination of the wetland boundaries should be commensurate with environmental features affecting on it which normally extend beyond water extent. ecological...

water scarcity is today’s world biggest challenge which requires different countries to manage their water resources in the most efficient way. sprinkler irrigation increases water consumption efficiency due to more uniform distribution of water across the field. precision farming is based on the site-specific use of inputs according to soil characteristics and plant needs. one of the main inpu...
