5 Foreword Anthropogenic geomorphology is the study of the role of humans in creating landforms and modifying the operation of geomorphological processes such as weathering, erosion, transport and deposition. As the human population rises, new lands and resources are exploited, and new technologies are adopted, the impact of humans grows ever greater. Some landforms are produced by direct anthropogenic actions. These tend to be relatively obvious in form and are frequently created deliberately and knowingly. They include landforms produced by construction (e.g. spoil tips from mines), excavation (e.g. mining and quarrying), hydrological interference (e.g. the building of dams), farming (including cultivation, grazing and horticulture) and military activities (e.g. craters). On the other hand, landforms produced by indirect anthropogenic actions are often more difficult to recognise, because they tend to involve the acceleration of natural processes rather than the operation of new ones. They result from environmental changes brought about inadvertently by human actions. By removing or modifying land cover through cutting, bulldozing, burning and grazing humans have accelerated rates of erosion and sedimentation. Sometimes the results of inadvertent actions are spectacular, as for example when major gully systems develop following deforestation, extreme floods are generated by impermeable urban surfaces, subsidence features open up when groundwater is mined, lakes become desiccated as a result of inter-basin water transfers, and mass movements like landslides are triggered by loading of slopes. Rates of rock weathering may be modified because of the acidification of precipitation caused by accelerated sulphate and nitrate emissions or because of accelerated salinisation in areas of irrigation and vegetation clearance. There are situations where, through a lack of understanding of the operation of geomorphological systems, humans have deliberately and directly altered landforms and processes and thereby have caused a series of events which were neither anticipated nor desired. There are, for example, many records of attempts to reduce coastal erosion by using imposing and expensive hard engineering solutions, which, far from solving erosion problems, only exacerbated them. This has profound implications for land management. v

6 vi Foreword Finally, the possibility that the buildup of greenhouse gases in the atmosphere may cause enhanced global warming in coming decades has many implications for anthropogenic geomorphology. This valuable book provides an overview of impacts from most types of human activity, demonstrates the value of a historical approach, and although it has a special emphasis on Hungarian research, provides examples from all over the world.
