Fig. 6.3.1. Income and expenses of agroforestry on marginal lands [1]. Key: green = Leaf fodder, red = Fruit, grey = Firewood, yellow = Payments for CO2 sequestration,
black = Expenditures; 1...7 = Years; vertical axis = Euro/ha
The maximal profit of 3500 Euro/ha came from Russian olive (E. angustifolia) due to the annual
income from fruit selling. The fruit yields decreased over the 7-year-long period as plantations
became too thick with growth and needed thinning. The firewood harvested from Euphrates poplar
(P. euphratica) gave a profit of 2300 Euro/ha, which was also a significant contribution to the total
profit of agroforestry. The profit of leaf fodder production was insignificant.
