Faced with multiple internal and external challenges, urban environments are increasingly searching for instruments adequate for achieving their sustainability goals. Different forms of urban nature can represent such instruments of addressing new societal ambitions, but in the same time can determine the emergence of urban environmental conflicts. We present an overview of how urban nature can become trigger and influencing factors for environmental conflicts under different policy contexts and how we can research and resolute conflicts of key urban actors by increasing public participation in the decision-making process. Environmental conflicts involving urban nature are presented across different elements, such as urban green and blue areas, urban biodiversity, protected areas or urban agriculture. We advocate for nature-based solutions as an integrated manner of including nature in urban areas without environmental conflicts emerging.
