Social Valuation of Mediterranean Cultural Landscapes: Exploring Landscape Preferences and Ecosystem Services Perceptions through a Visual Approach

Peer-reviewed publication
September, 2020
United States of America
Spain

Mediterranean cultural landscapes have been recognized as multifunctional landscapes that are currently threatened by two opposing trends: rural abandonment and agricultural intensification. Uncovering people’s perceptions of different landscape configurations, and how inhabitants value the contributions of nature to human wellbeing, is essential to understanding current landscape trends.

The Grain for Green Project May Enrich the Mercury Concentration in a Small Karst Catchment, Southwest China

Peer-reviewed publication

United States of America
China
Russia

The Chinese project, better known as the Grain for Green Project (GGP), has changed the land-use type in the karst area of Puding county, Guizhou province, southwest China, and this study is aimed at evaluating the Hg distribution and determining factors in soils after the land-use change. A total of ten soil profiles were selected in the typical karst region, and the land-use types were divided into native vegetation land (NVL), farmland (FL), and abandoned farmland (AFL).

Uncovering Ecosystem Services of Expropriated Land: The Case of Urban Expansion in Bahir Dar, Northwest Ethiopia

Peer-reviewed publication
September, 2020
Ethiopia

In Ethiopia, urban expansion happens at high rates and results in land expropriations often at the cost of agriculture and forests. The process of urban expansion does not include assessment of ecosystem services (ES). This has been causing unintended environmental problems. This study aims to uncover ES of three most important land use types (cropland, agroforestry, and grassland) that are threatened by land expropriation for urban expansion in Bahir Dar City. The study applied a participatory approach using community perception and expert judgments (N = 108).

Cost-Benefit Analysis of Landscape Restoration: A Stocktake

Peer-reviewed publication
October, 2020
Global

With the increase in demand for landscape restoration and the limited resources available, there is need for economic analysis of landscape restoration to help prioritize investment of the resources. Cost-benefit analysis (CBA) is a commonly applied tool in the economic analysis of landscape restoration, yet its application seems limited and varied. We undertake a review of CBA applications to understand the breadth, depth, and gaps. Of the 2056 studies identified in literature search, only 31 met our predefined criteria.

Differences in the Soil Quality Index for Two Contrasting Mediterranean Landscapes in Southern Spain

Spain

Soil quality indexes (SQIs) are very useful in assessing the status and edaphic health of soils. This is particularly the case in the Mediterranean area, where successive torrential rainfall episodes give rise to erosion and soil degradation processes; these are being exacerbated by the current climate crisis. The objective of this study was to analyze the soil quality in two contrasting Mediterranean watersheds in the province of Malaga (Spain): the middle and upper watersheds of the Rio Grande (sub-humid conditions) and the Benamargosa River (semi-arid conditions).

Developing a UML Model for the 3D Cadastre in Poland

Peer-reviewed publication
October, 2020
Poland

The UML model of a land and building cadastre is defined in current Polish legal regulations. Its main part is the UML application schema that defines relationships between the main cadastral objects in sixteen diagrams. These objects—cadastral parcels, buildings and (independent) premises—are essentially 2D objects. Their relationships with other cadastral objects are compared and analysed in this paper.

Applying Geomorphic Principles in the Design of Mountain Biking Singletracks: Conceptual Analysis and Mathematical Modeling

Peer-reviewed publication
October, 2020
United States of America

Mountain biking, also known as singletracking, is an emerging sector in outdoor recreation activities. Experience shows that although bicycling is considered a low-impact activity, singletracking may have adverse environmental footprints. Here, we review and conceptually analyze the forces applied on singletracks, and implement mathematical modeling of these forces, for a range of climatic conditions and geographic settings. Specifically, we focus on the hydrological and geomorphic impacts of singletracking, and highlight the importance of applying geomorphic principles in their design.

A Regression-Based Procedure for Markov Transition Probability Estimation in Land Change Modeling

Peer-reviewed publication
October, 2020
Norway

Land change models commonly model the expected quantity of change as a Markov chain. Markov transition probabilities can be estimated by tabulating the relative frequency of change for all transitions between two dates. To estimate the appropriate transition probability matrix for any future date requires the determination of an annualized matrix through eigendecomposition followed by matrix powering. However, the technique yields multiple solutions, commonly with imaginary parts and negative transitions, and possibly with no non-negative real stochastic matrix solution.

From the Ground Up: Prairies on Reclaimed Mine Land—Impacts on Soil and Vegetation

Peer-reviewed publication
October, 2020
United States of America

After strip mining, soils typically suffer from compaction, low nutrient availability, loss of soil organic carbon, and a compromised soil microbial community. Prairie restorations can improve ecosystem services on former agricultural lands, but prairie restorations on mine lands are relatively under-studied. This study investigated the impact of prairie restoration on mine lands, focusing on the plant community and soil properties. In southeast Ohio, 305 ha within a ~2000 ha area of former mine land was converted to native prairie through herbicide and planting between 1999–2016.

Effect of Vegetation Removal on Soil Erosion and Bank Stability in Agricultural Drainage Ditches

Peer-reviewed publication
October, 2020
Hungary
Germany

Maintenance of agricultural drainage ditches can be difficult to optimize if farmers have no guidelines on where to target their maintenance efforts. A main concern is whether ditch banks will experience soil erosion or mass movement (failure). In order to help identify sites that are more likely to experience soil erosion and/or mass movement, soil susceptibility to detachment was assessed in this study using a cohesive strength meter (CSM) and measurements of shear strength in unsaturated direct shear tests.

State-Customary Interactions and Agrarian Change in Ghana. The Case of Nkoranza Traditional Area

Peer-reviewed publication
October, 2020
Ghana

While agrarian change has been a recurrent theme in Ghana’s endeavor for economic development, questions on how land resources should be managed to ensure prompt attainment of economic growth remain unanswered. In Ghana, land is controlled by customary actors, while the state is the custodian of agricultural policies. The need for interaction between the two actors to ensure that the envisioned economic gains from agriculture are attained is paramount.

An Evaluation of Public Spaces with the Use of Direct and Remote Methods

Peer-reviewed publication
October, 2020
Global

Public spaces play many important roles and constitute a vital component of the urban fabric, in particular in towns with historical centers. Effective management of public space should be based on the results of qualitative assessments. The quality of public space is usually evaluated directly during field surveys. However, field methods require considerable effort and time, which is why a remote sensing method based on satellite images and the Street View technology was proposed in this paper.
