Sustainability · 2025

Key Findings

0176.4% of terraces fall within meso and macro classes.
0258% of terraces show partial or complete functional degradation.
03Cohesive terrace clusters are located near settlements, while isolated units in peripheral zones display higher vulnerability.

Application

Design takeaway

How to apply

Utilize drone surveys and GIS analysis to map and assess the functional integrity of terraced agricultural land in your region, identifying priority areas for conservation or restoration.

Project actions

01Consider using drone imagery for your design project if it involves analyzing existing landscape features or infrastructure.
02Explore GIS tools to process and analyze spatial data for a more comprehensive understanding of your design context.

Method & Evidence

AimTo develop and apply an integrated framework using UAV photogrammetry and GIS to assess the functional status of agricultural terraces in mountainous regions for sustainable land management.

MethodSpatial-spatial-functional assessment framework integrating UAV-based photogrammetry, GIS analysis, terrain modeling, and DBSCAN clustering.

ProcedureHigh-resolution topographic data was acquired using UAVs. This data was used to delineate terrace boundaries and classify them morphometrically using an adapted ALPTER model. A combined Terrace Density Index (TDI) and Functional Status Index (FSI) was then applied to identify areas with structurally intact but functionally degraded terraces.

ContextMountainous agricultural landscapes with traditional terrace systems.

Variables

IV["Terrace characteristics (e.g., size, slope, density)","Location relative to settlements"]

DV["Functional status of terraces (e.g., partial or complete degradation)","Structural integrity of terraces"]

CV["Topographic data resolution","GIS analysis parameters","DBSCAN clustering algorithm settings"]

Strengths & Limitations

Strengths

+Integration of multiple advanced technologies (UAV, GIS, photogrammetry).
+Development of a novel spatial-functional assessment framework.

Limitations

The cost of drone equipment and specialized software can be a barrier. Processing large amounts of photogrammetric data requires significant computational resources and expertise.

Reliability & validity

The reliability of the findings is supported by the use of established photogrammetric and GIS techniques. Validity is enhanced by the integration of multiple indices (TDI, FSI) and clustering algorithms to cross-reference findings.

Think critically

How might the socio-economic factors mentioned (land abandonment, socio-economic decline) directly influence the functional degradation observed in the terraces, and how could design interventions address these root causes?

Design Principles

"Data-driven assessment of existing infrastructure is essential for effective sustainable land management and heritage conservation."

Understanding the current state of traditional agricultural infrastructure like terraces is crucial for sustainable land management. This research provides a scalable, data-driven method to assess their condition, enabling informed decisions for conservation, restoration, and preventing further environmental and cultural loss.

What This Means for Your Design

Drones can take detailed pictures of old farm terraces on hillsides, and computer analysis shows that more than half of them aren't working as well as they should, meaning they're not holding water or soil properly anymore.
