Land is a limited resource. Its use for one purpose excludes other uses. Addressing the issue of human appropriation of natural resources thus requires understanding of a variety of complex feedbacks between decisions on land use and ecosystem services. The complexity is caused by a large number of mostly nonlinear feedbacks between management strategies, productivity, environmental quality, human well-being, consumption and many other aspects of land use. Here, we present LandYOUs: an educational online game, which aims at explaining and illustrating various options and feedbacks of sustainable land management (SLM) to the interested public, students and stakeholders. The game gives the player an opportunity to govern a country by means of land use, nature protection and education. One can explore how sometime contrasting dimensions of sustainability with respect to economic, social and environmental conditions can be balanced on a regional scale while being continuously threatened by global trade fluctuations and limited resources. The game was tested by several groups of students from high schools and universities. Based on this testing, we received valuable information on how the game is perceived and understood by the players. The feedback suggests that the game has a potential to be used for educational purposes, environmental planning or stakeholder meetings.
