► Water availability and demand mismatches can be acute across Mongolia's breadbasket.Bataa and I met in 1995 in the Mongolian capital, Ulan Bator.I was struck by how lovely and close-knit his family were.In Bataa’s family the women milk the animals and take care of the household and children, while the men do the lion’s share of the herding.► The western breadbasket experiences a swinging pendulum of hydroclimatic regimes.► Results suggest the eastern breadbasket has a steadier delivery of moisture.
In its continuing move toward resource independence, Mongolia has recently entered a new agricultural era.
All split, calibration-verification statistics were positive, indicating significant model reconstruction.
Reconstructed Yeruu River streamflow indicates the 20th century to be wetter than the two prior centuries.
RCS growth of both species was negatively correlated with winter temperatures, but Mongolian pine depended most strongly on previous December to current February temperatures and Dahurian larch depended most strongly on March temperatures. We found similar long-term changes of tree-ring δC in the two species.
Carbon isotopic discrimination of Dahurian larch and Mongolian pine was determined mainly by growing season temperature (positive) and moisture (negative), but with different signal strengths, suggesting that stomatal conductance influenced tree-ring δ will not improve tree growth sufficiently to compensate for temperature-induced water stress.
