It was calculated that agroforestry as a land reclamation practice resulted in irrigation water savings 
of  up to 35000-40000 m

/ha within the 7 year period. However, these figures can be doubled with 
the inclusion of  water used on soil leaching under annual crops. Therefore, the total cost of  water 
savings in agroforestry can be estimated at around 500-600 Euro/ha.
Generally, agroforestry is preferable to annual crop cultivation on degraded lands because of  its 
cost effectiveness and water saving benefits. The income and expenses of  agroforestry on marginal 
lands are illustrated in detail in Figure 6.3.1.

The analysis shows that maximal investment is needed at the initial stage of  the implementation 
of  agroforestry practices, which includes tree planting costs and the development agreement cost 
within the framework of  the Clean Development Mechanism (on average about 700 Euro/ha). 
Subsequent expenses are relatively smaller and include the costs of  irrigation, weeding, pruning, 
thinning, fruit harvesting and tree cutting at the end of  the 7-year-long rotation period. The 
income to expense ratio had the following values: 3.5, 1.8 and 1.4 for E.angustifoliaP. euphratica and 
U. pumila, respectively.
