[1] Global food security increasingly relies on the trade of food commodities. Freshwater resources are essential to agricultural production and are thus embodied in the trade of food commodities, referred to as ‘‘virtual water trade.’’ Agricultural production predominantly relies on rainwater (i.e., ‘‘green water’’), though irrigation (i.e., ‘‘blue water’’) does play an important role. These d...

Characteristics of Lake Chad Level Variability and Links to ENSO, Precipitation, and River Discharge
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 ...
