Abstract
The article points out natural and anthropogenic factors contributing to the
formation, development and alteration of agricultural landscapes in western Georgia,
specifically, in the Colkheti coastal plain and the adjacent hilly foothill zone, where
subtropical agriculture used to be heavily developed (tea and citrus plantations, etc.). The
former state-owned tea farm zone in the borough of Laituri, Ozurgeti municipality, Guria
was selected as the study location. GIS technologies were applied to digitalize the 1960
landscape map of the zone and create its new version (1:50 000) as of 2017 based on the
topographical map of 1960 (1:50 000), satellite images and field observations (2010-2017).
The analysis of the Laituri 1960 and 2017 landscape showed that 66% of tea plantations
have been amortized and degraded: they have gone wild and are overtaken by weeds. Due to
high costs involved, only 10% of the area was cleared to cultivate hazel nuts, blue
huckleberry and persimmon. 24% of tea plantations survive to varying degrees and are
currently harvested.
