To combat desertification and land degradation in arid and semi-arid zones, the government has adopted an approach of rehabilitation of pasturelands through forage plantations. This program was launched at the beginning of the 1990s and, to date, there has been no global or national study on the sustainability of the program, particularly its economic profitability. Our work’s principal objective was to perform an economic analysis of the forage plantation program across the different periods since the creation of the program until the year 2020, focusing on the economic evaluation parameters of the projects, such as mean annual net income, net present value, annuity of the net present value, profitability index and payback period, based on the data collected from the official institutions. The results showed that the forage plantation program significantly contributes to sustainable development in steppe areas.
