Fig. 4: Schematic diagram illustrating the adaptive response of subsistence practices (arable agriculture and pastoralism) at Angrenjin Co and the surrounding area in the STP to drought intensification over the past 3600 years.
From: 3,600 years of human adaptation to drought intensification on the southern Tibetan Plateau

A Weaker grazing activity, stronger farming activity and decreased local fire activity during a relatively wet climatic phase with low evaporation (3600–1800 cal year BP); B Stronger grazing activity, weaker arable farming activity and increased local fire occurrence during a drier climatic phase with higher evaporation (after 1800 cal year BP).
