The surface area of drylands affected by desertification is estimated at 10-20% of this land, making this one of the worst environmental problems worldwide. Measures to combat desertification include restoration actions. Recent advances in our understanding of dryland ecology have improved traditional restoration techniques and fostered the development of new eco-technology. However, the refinement of eco-technological tools and the success of experimental restoration projects have not been accompanied by parallel increases in the efficiency and reliability of management-scale restoration programs. In our experience, this is the result of uncertainties about the long-term effects of restoration actions, scarce knowledge on population and community dynamics, and cultural and socioeconomic constraints to the implementation of new techniques and the improvement of traditional ones. We suggest that i) adopting the ecosystem service approach to identify restoration targets and evaluate restoration actions, ii) integrating restoration actions into comprehensive development programs, and iii) creating networks of pilot and demonstration projects may foster participative, adaptive and integrative management plans, and contribute to livelihood quality in desertified areas.
