Also restoring forests may have adverse effect, I've heard different researches on this topic.

  Yes, there are dangers in restoring forests. I'm thinking of China's Three North Shelter Program here. While very ambitious and farsighted, the monocultures they establish are vulnerable to diseases, pests and other factors, and are a weak starting point to rebuild ecosystems. If those trees die, all the resources put into the effort will go to waste. Also, the new forests put heavy strain on the water table, which worsens the effects of desertification. The water table can only recover if the forests become strong and dense enough to retain humidity and cool down the ground. My (totally uneducated) advice would be to strengthen existing forests and ecosystems, merge them (if necessary, by reallocating agricultural use to other ares) and slowly expand them towards the affected areas.
