Most land use (change) decisions are still based on incomplete information about the real welfare effects (costs and benefits) because many so-called externalities (positive and negative) associated with the change in land use and management are neglected. This leads to loss and degradation of ecosystems and their services affecting human well-being. Worldwide more than 25% of the land surface is now more or less degraded (UNCCD Global Land Outlook, 2017), costing between 4 and 20 trillion US$/year in terms of damage, repair or replacement costs (Costanza et al., 2014). Better information is therefore needed on the benefits (monetary and non-monetary) of conservation, restoration and sustainable use of ecosystems and landscapes. To assess the multiple benefits of nature conservation, landscape restoration and sustainable land management in a systematic, effective and efficient way, good guidelines supported by practical tools and online databases, are essential.
