In order to understand the role of wild bees in both social and ecological systems, we conducted a quantitative and qualitative review of publications dealing with wild bees and the benefits they provide in social contexts. We classified publications according to several attributes such as services and benefits derived from wild bees, types of bee–human interactions, recipients of direct benefits, social contexts where wild bees are found, and sources of changes to the bee–human system. We found that most of the services and benefits from wild bees are related to food, medicine, and pollination. We also found that wild bees directly provide benefits to communities to a greater extent than individuals. In the social contexts where they are found, wild bees occupy a central role. Several drivers of change affect bee–human systems, ranging from environmental to political drivers. These are the areas where we recommend making interventions for conserving the bee-human system.

Abstract
Transformation, transition and regime shift are increasingly applied concepts in the academic literature to describe changes in society and the environment. Ecosystem services represent one framework that includes the implicit aim of supporting transformation towards a more sustainable system. Nevertheless, knowledge and systematic reviews on the use of these concepts within ecosystem services research are so far lacking. Therefore, we present a systematic literature review to analyse the interlinkages between these concepts and ecosystem services. Using a search string we identified 258 papers that we analysed based on 40 review criteria. Our results show that transformation was mentioned most often (197 articles), followed by transition (183 articles) and regime shifts (43 articles). Moreover, there is no consolidation of these concepts. Only 13% of all articles gave definitions for the three concepts. These definitions strongly overlapped in their use. Moreover, most papers described changes that happened in the past (73%). We conclude that research would benefit from being directed towards the future rather than evaluating what has happened in the past. Based on our results, we present: i) clear definitions for the three concepts; and ii) a framework highlighting the interlinkages between the ecosystem services cascade and the concepts of change.
