“…The Promontory of Portofino is located roughly at the center of the Ligurian coastline and breaks the continuity of the coastline between Genova and La Spezia (Figure 1A). The orography [31] shows rather high altitudes related to the distance of the coastline: an WNW-ESE-oriented relief with Mounts Tocco (543 m), Portofino (610 m), delle Bocche (506 m) and Pollone (472 m) is easily recognized. Most of the hydrographic catchments are less than 1 km 2 wide, with channels of the 2nd order at the most.…”

“…The identification of dry-stone walls allowed us to obtain a theoretical surface without terraces through a natural neighbor interpolation (Figure 5). Thus, by computing the difference between this smoothed surface and the real one, an estimation of the anthropogenic remolded volume was obtained according to the method developed by Cucchiaro et al [31]. The procedure may underestimate or overestimate the real volume, considering that the real surface under terraces may follow a concave or convex shape.…”

“…Paired survey methods are often used to overcome each other's limitations [29]. HRT techniques allow us to obtain high-resolution digital terrain models (DTMs) from which high-precision parameters can be extracted, enabling the geometric definition of terraces [30,31] in a GIS environment. The original geometry of the terraces is of primary importance for the definition of the movable volumes during an unstable landslide or debris flow to establish the potential extent of impacts.…”

Terraced landscapes are widely applied in many mountainous regions around the world as a result of the necessity to practice subsistence agriculture. Hence, they can be regarded as one of the most diffused anthropogenic modifications of the Earth’s surface. Different techniques have been used for their implementation leading to the artificial immobilization of debris and soil along the slopes whose surface is interrupted by a sequence of sub-horizontal and sub-vertical areas often using stone walls. In some areas of the world, such interventions are thousands of years old and their resistance to the degradation caused by the morphogenetic system can be attributed to the permeability of the stone walls as well as to their regular maintenance. In some other areas, the lack of maintenance has been the main cause for degradation processes ending with their collapse. The effects of climate change manifested through higher intensities and higher frequencies of rainfall are likely to accelerate the degradation process further by causing terraces to act as a source of debris or hyperconcentrated flow. This will in turn increase the severity of geo-hydrological hazards. The measures concerning reduction of geo-hydrological hazards caused by are sought through identification of abandoned terraces and assessment of the potential for their sudden collapse. The present paper describes a framework for identification of abandoned terraces and estimation of the potential volume of shallow landslides that can be generated. The research conducted aims to advance the existing hazard assessment practices by combining numerical modeling with processing of high-resolution LiDAR data. A new algorithm is developed to support localization of terraces. The catchment scale approach applied to eight smaller catchments enables estimation of the total volume of soil and debris trapped along the slopes. It also generated some important quantitative data which will be used in the future risk assessment work. The work has been carried out within the EU-funded H2020 project RECONECT.

The history of agricultural terraces dates back to agricultural society; and throughout history, they have enabled agricultural activities to be carried out on lands with irregular relief. They have also served as an essential element of rural landscapes due to their architectural features, building materials, and techniques, as well as the landscapes they create. Furthermore, terraces also contribute to soil conservation by preventing erosion, adding organic matter to the soil, and harvesting rainwater. The significance of agricultural terraces in the cultural landscape has triggered the need to define and classify them. In this regard, agricultural terraces across many different locations have found their place on the List of Globally Important Agricultural Heritage Sites (GIAHS) and UNESCO cultural heritage lists. In the present study, the agricultural terraces of the Erikli neighborhood of the Uzundere district were mapped through surveys, drone shots, and orthophotos, and analyzed based on the size and density indices previously used in the classification of Alpine terraces. The study is important in terms of demonstrating the use of drone technology in mapping agricultural terraces. The results of the study revealed that 51.6% of the agricultural terraces in the study area had very steep slopes and 22195 meters of total stone wall length, the average density index was 523.29 m/ha, and 76.4% of the terraces were meso and macro in character. Moreover the study shows that the terraces in the region are more susceptible to deterioration.
