This paper applies a resilience- and assemblage-based methodology to study the socio-ecological dynamics of human responses in the land degradation-affected Messara Valley (Crete, Greece) socio-ecological system, from 1950 to 2010. It posits that thesedynamics aredriven by changes in their effectiveness, called ‘socio-ecological fit’, to serve place- and time-specific goals.
Investigating Semi-Automated Cadastral Boundaries Extraction from Airborne Laser Scanned Data
Many developing countries have witnessed the urgent need of accelerating cadastral surveying processes. Previous studies found that large portions of cadastral boundaries coincide with visible physical objects, namely roads, fences, and building walls. This research explores the application of airborne laser scanning (ALS) techniques on cadastral surveys. A semi-automated workflow is developed to extract cadastral boundaries from an ALS point clouds. Firstly, a two-phased workflow was developed that focused on extracting digital representations of physical objects.
The Dynamics of Urban Land Rent in Italian Regional Capital Cities
This research tries to interpret the results of the empirical analysis of urban land value variations from 1977 to 2012 in the regional Italian capital cities based on the well-known theory of urban land rent. The historical series to be analyzed were obtained as the difference between the market value of a property and its cost of production. The paper shows, in quantitative terms, how differential and absolute rents will be translated into the dynamics of land values in relation to local specificities.
Informal Urban Green Space: Residents’ Perception, Use, and Management Preferences across Four Major Japanese Shrinking Cities
Urban residents’ health depends on green infrastructure to cope with climate change. Shrinking cities could utilize vacant land to provide more green space, but declining tax revenues preclude new park development—a situation pronounced in Japan, where some cities are projected to shrink by over ten percent, but lack green space. Could informal urban green spaces (IGS; vacant lots, street verges, brownfields etc.) supplement parks in shrinking cities?
High-Resolution Vegetation Mapping in Japan by Combining Sentinel-2 and Landsat 8 Based Multi-Temporal Datasets through Machine Learning and Cross-Validation Approach
This paper presents an evaluation of the multi-source satellite datasets such as Sentinel-2, Landsat-8, and Moderate Resolution Imaging Spectroradiometer (MODIS) with different spatial and temporal resolutions for nationwide vegetation mapping. The random forests based machine learning and cross-validation approach was applied for evaluating the performance of different datasets.
