Whereas the previous two chapters considered two alternative economic approaches on deciding when to restore natural capital, this chapter reflects on the lessons learnt by the Millennium Ecosystem Assessment (MA) for the assessment and restoration of natural capital, mostly from an ecological perspective. At the outset it should be stated that it is not easy to restore ecosystem services or biodiversity with our current paradigms and ecological tools. Though we understand intuitively that local natural capital is profoundly influenced by patterns and processes in the broader environment, it is difficult to translate abstract insights into practical actions for assessment and restoration. The MA therefore endeavors, vigorously, to improve our ability to gain insights about ecosystem services across spatial and temporal scales.
