“…Addressing stakeholders first has the advantage that observations that were important to the interviewees or important information about certain management changes can help to inform decisions on which landscape changes to map (Isager and Broge 2007 ; Berget et al 2021 ). Further, it can give insights into temporal land uses (Mathur and Bhattacharya 2023 ) or land uses that are not captured through remote sensing data (Fox et al 2017 ). An exchange with local stakeholders further makes it possible for landscape changes seen as important by the stakeholder to be prioritized by the remote sensing approach, such as the change in number of trees and hedges in IEV, REU and SMP.…”

Context Anthropogenic landscape change is an important driver shaping our environment. Historical landscape analysis contributes to the monitoring and understanding of these change processes. Such analyses are often focused on specific spatial scales and single research methods, thus covering only limited aspects of landscape change. Objectives Here, we aim to assess the potential of combining the analysis of historical aerial imagery and local stakeholder interviews for landscape change studies using a standardized mapping and interviewing approach. Methods We compared six agricultural landscapes across Europe and mapped land-cover using historical aerial imagery (starting between 1930 and 1980, depending on data availability, until recent years) with an object-based image analysis and random forest classification. For local perspectives of landscape change, we conducted oral history interviews (OHIs) with (almost) retired farmers. Comparing recorded landscape changes from both approaches provided insight into advantages of combining these two methods. Results Object-based analysis enabled the identification of high-resolution land-cover dynamics, with scale enlargement and cropland/grassland expansion being the most commonly recurring trends across European landscapes. Perceived landscape changes identified in the OHIs included changes in farm management, landscape structure, and infrastructure. Farmers also reported drivers and personal values associated with landscape change. Combining the two historical landscape analysis tools resulted in a qualitative and quantitative understanding of changes in land-cover, land use, and land management. Conclusions Comparing physical land-cover change with local farmer perspectives is key to a comprehensive understanding of landscape change. There are different ways the two methods can be combined, leading to different venues for science and policy making.

The history and revival of swidden agriculture research in the tropics

Swidden agriculture used to occur in the temperate zones and currently occurs almost exclusively in the tropics. Academic research on the millennium-long farming system did not occur until the mid-eighteenth century, followed by scattered and sporadic research work before the twentieth century. So far, a thematic review of the history of swidden agriculture research based on the Institute for Scientific Information (ISI) Web of Science, which provides the longest coverage from 1900 to the present, has not yet been reported. The lack of a 20th-century literature review restricts understanding the revival of swidden agriculture research. With the journal publications (including Articles, Review Articles, and Data Papers) indexed by Web of Science and Google Scholar, we divided the history of swidden agriculture research into three developmental stages: descriptive transcription, critical analysis, and comprehensive analysis, with the years of 1957 and 2008 as the watershed years, respectively. Notably, 2008 emerged as a watershed year for the revival of swidden agriculture research in the tropics. Launching and implementing the United Nations Collaborative Programme on Reducing Emissions from Deforestation and Forest Degradation in Developing Countries promotes top-down rethink and rediscovery. In contrast, the free Landsat archive provides bottom-up support for consistent historical satellite observations. The synchronic emergence of the UN-REDD Programme and the free Landsat data policy may be coincidental. Yet, their combination and the global economic crisis since 2008 have become a catalyst and impetus for putting the longitudinal and horizontal analyses of swidden agriculture together. After a century of debate, swidden agriculture is gaining the academic attention it deserves.
