In the last few years, terraced landscapes have been receiving renovated interest all over the world (e.g., dry-stone walls named UNESCO heritage in November 2018). Terracing was recognized as a fundamental component of agricultural systems, both for its cultural value as well as for its importance in guaranteeing food production in unfavorable environments. Consequently, the scientific community has started to investigate the environmental effects related to terracing. In this framework, hydrological and hydrogeological processes occurring in terraced landscapes are of the utmost interest for their implications related to land and water management in different areas of the world.
The latest studies showed that terracing represents a radical alteration of pre-existing terrain settings, thus altering water infiltration and runoff generation processes, and ultimately influencing the entire water cycle from the single terrace up to the slope, catchment, and landscape scales. In some of the agricultural areas of the world, and especially where high slopes are present and/or land degradation issues occur, sound terracing implementation and terraced landscape restoration can contribute to reducing hydrological and hydrogeological hazards, as well as soil erosion and landsliding. This latter effect can be relevant both at the local scale, reducing hazard to agricultural areas, and at a catchment scale, reducing hazards to downstream population and infrastructures. On the other hand, deteriorating terraced systems, as well as poorly managed or designed terraces, may increase these hazards, even enhancing the trigger of degradation phenomena. A specific research focus on terrace deterioration mechanisms (such as collapse and bulging) and on their consequences is also needed.
Recent developments in scientific and engineering research techniques, such as remote sensing, offer the possibility of increasing knowledge of the terracing–hydrogeological hazard relationship, including, for instance: Advanced and detailed geomorphological analysis, hydraulic, geotechnical, and hydrological modeling.
The aim of the present Special Issue is to gather studies related to the relationship between terraced landscapes and hydrogeological hazards. We encourage the submission of research papers and reviews dealing with hydrological–geological risk mitigation given by terraced landscapes, with the potential hazards induced by degraded and/or abandoned terracing, and with effective terraces management strategies.
Contributions from African, South East-Asian, and Latin American countries, and from experiences of recently developed terracing projects are highly welcome for the Special Issue.
Key issues that can be addressed include but are not limited to:
- Hydrological, geohydrological, and hydraulic analysis of terraced catchments, hillslopes or plots, including both experimental data and modeling approaches;
- Drainage design and runoff collection methods at the scale of terraced landscapes, including both artificial and natural drainage networks;
- Management and mismanagement case studies of terraced landscapes;
- Analysis and/or modeling of the main terraces collapse mechanisms, including bulging;
- Vegetation effects during cultivation or after short- and long-term abandonment.
