For the past five years Abderrazzak Sibri hasn’t harvested a single olive from the 357 olive trees on his land in Sidi Mahmoud, a rural town in the province of Kairouan (central Tunisia). Sibri had planned to plant more olive trees, but lack of rain, several years of draughts and decreased ground water levels impacted production and changed his plans. “What bothers me most is that I have been investing in these trees,” he says. “When they finally reach the age in which they can produce regularly and abundantly, there is no more water to keep them growing.”
