Battir's dry-stone terraces near Bethlehem are fed by the hakura system, a time-shared spring-water rotation among village families. UNESCO inscribed the 348-hectare landscape as a World Heritage site in 2014 - the same day it was listed as in danger.
The village of Battir, on the slopes below Bethlehem in the West Bank, maintains one of the last intact ancient terrace-and-spring irrigation landscapes in the eastern Mediterranean. Farmers still grow olives, grapes and vegetables on dry-stone terraces fed by a spring-based canal network that written and archaeological evidence trace back at least to Roman times, with local tradition holding the system predates that.
Water is allocated through the hakura system: each of Battir's eight families receives an exclusive time slot -- calculated by a simple, centuries-old mathematical division of the week -- during which the spring's full flow is diverted to their terraces. The rotation requires no meters, courts or fees, only continuous community maintenance of the channels and walls.
On 20 June 2014, UNESCO's World Heritage Committee inscribed 'Battir - Land of Olives and Vines, Cultural Landscape of Southern Jerusalem' (348 ha core, 623 ha buffer) -- and simultaneously placed it on the List of World Heritage in Danger, citing the threat of Israel's planned separation barrier route through the terraces. Sustained advocacy by the Battir village council, UNESCO and international heritage bodies contributed to Israel's High Court provisionally halting construction through the site the following year.
The system faces real, unresolved pressure: prolonged drought and hotter summers are reducing the spring's groundwater recharge, more intense short-duration rainfall is accelerating wall erosion, and renewed Israeli settlement-expansion plans near the site were reported as recently as 2024 -- so Battir remains a live case of heritage-based water-and-soil management under strain, not a finished success story.
