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

Peer-reviewed publication
Septiembre, 2020
Estados Unidos de América
España

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.

Transformation of Industrial Land in Urban Renewal in Shenzhen, China

Peer-reviewed publication
Septiembre, 2020
China

The redevelopment and transformation of industrial land has become an important part of urban renewal in China. This study adopts a spatial perspective to investigate the transformation of industrial land in Shenzhen based on a set of reliable data of all urban redevelopment projects of industrial land from 2010 to 2018. Research shows that the development of the real estate market, local government’s strategic demand for upgrading industrial structure, and the policy objective of improving land use intensity are important factors that affect the industrial land transformation.

Extent of Soil Acidity in No-Tillage Systems in the Western Cape Province of South Africa

Peer-reviewed publication
Septiembre, 2020
África austral
Sudáfrica
Islas Turcas y Caicos

Roughly 90% of farmers in the Western Cape Province of South Africa have converted to no-tillage systems to improve the efficiency of crop production. Implementation of no-tillage restricts the mixing of soil amendments, such as limestone, into soil. Stratification of nutrients and pH is expected. A soil survey was conducted to determine the extent and geographical spread of acid soils and pH stratification throughout the Western Cape. Soil samples (n = 653) were taken at three depths (0–5, 5–15, 15–30 cm) from no-tillage fields.

Implementation and Advancement of a Rural Residential Concentration Strategy in the Suburbs of Shanghai

Peer-reviewed publication
Septiembre, 2020
China
Reino Unido

Rural residential concentration was one of the important tasks of the “Three Concentrations” strategy implemented in the suburbs of Shanghai in the mid-1990s. The aims of this paper are to comprehensively evaluate the process, pattern and effects of residential concentration in the suburbs of Shanghai over the past 20 years, clarify the direction and focus of development, and propose suggestions for existing deficiencies.

Evaluating the Efficiency of Different Regression, Decision Tree, and Bayesian Machine Learning Algorithms in Spatial Piping Erosion Susceptibility Using ALOS/PALSAR Data

Peer-reviewed publication
Septiembre, 2020
Irán

Piping erosion is one form of water erosion that leads to significant changes in the landscape and environmental degradation. In the present study, we evaluated piping erosion modeling in the Zarandieh watershed of Markazi province in Iran based on random forest (RF), support vector machine (SVM), and Bayesian generalized linear models (Bayesian GLM) machine learning algorithms.

Urban Cadastral Situation in Ecuador: Analysis to Determine the Degree of Proximity of the Cadastral Systems to the 3D Cadastral Model

Peer-reviewed publication
Septiembre, 2020
Ecuador

As 3D cadastres offer advantages in several areas by providing information with greater accuracy and a high level of detail, a diagnosis of the cadastral situation is required prior to the implementation of a 3D cadastral model. Therefore, this study focuses on diagnosing the urban cadastral situation in Ecuador based on an analysis of eight cantonal decentralized autonomous governments that were selected primarily for the availability of their cadastral information.

Impacts of Future Crop Tree Release Treatments on Forest Carbon as REDD+ Mitigation Benefits

Peer-reviewed publication
Septiembre, 2020
Belice
Bolivia
Guyana
Suriname
Estados Unidos de América

Sustainable forest management activities, such as future crop tree (FCT) release treatments, became part of the REDD+ strategy to avoid carbon emissions from forests. FCT release treatments are intended to achieve increased growth of FCTs by removing competitor trees. This initially leads to a reduction of the forest carbon pool and represents a carbon debt. We estimated that the time it takes for FCTs to offset the carbon debt through increased growth on experimental sites of 10 km² in Belize, Guyana, Suriname, and Trinidad and Tobago.

A Discounted Cash Flow and Capital Budgeting Analysis of Silvopastoral Systems in the Amazonas Region of Peru

Peer-reviewed publication
Septiembre, 2020
Perú

Silvopasture is a type of agroforestry that could deliver ecosystem services and support local livelihoods by integrating trees into pasture-based livestock systems. This study modeled the financial returns from silvopastures, planted forests, and conventional cattle-pasture systems in Amazonas, Peru using capital budgeting techniques. Forests had a lower land expectation value (USD 845 per hectare) than conventional cattle systems (USD 1275 per hectare) at a 4% discount rate.

Global and Regional Implications of Biome Evolution on the Hydrologic Cycle and Climate in the NCAR Dynamic Vegetation Model

Peer-reviewed publication
Septiembre, 2020
Global

Vegetation influences climate by altering water and energy budgets. With intensifying threats from anthropogenic activities, both terrestrial biomes and climate are expected to change, and the need to understand land–atmosphere interactions will become increasingly crucial. We ran a climate model coupled with a Dynamic Global Vegetation Model (DGVM) to investigate the establishment of terrestrial biomes starting from a bareground scenario and how these biomes influence the climate throughout their evolution.

Potential Impacts of Soil Tillage System on Isoflavone Concentration of Soybean as Functional Food Ingredients

Peer-reviewed publication
Septiembre, 2020
Europa
Rumania

Soybean is an important natural source of isoflavones, but their concentration is likely to be influenced by external factors, such as climatic conditions and soil tillage systems. However, there is minimal information about the effects of such external factors on the isoflavone concentration in soybeans grown in Europe.

Gatekeeping Access: Shea Land Formalization and the Distribution of Market-Based Conservation Benefits in Ghana’s CREMA

Peer-reviewed publication
Septiembre, 2020
Ghana

Community Resource Management Areas (CREMAs) in Ghana combine conservation and development objectives and were introduced in the year 2000. In some cases, they have connected collectors of shea (Vitellaria paradoxa) nuts with certified organic world markets, which can be understood as a ‘market-based’ approach to conservation. This paper examines how the benefits of this approach are distributed and argues that shea land formalization is crucial to this process. It makes this argument by drawing on interviews within two communities bordering Mole National Park.

Owner or tenant: Who adopts better soil conservation practices?

Peer-reviewed publication
Agosto, 2015
República Checa
Noruega

Land tenure security is widely considered to be a fundamental factor in motivating farmers to adopt sustainable land management practices. This study aims to establish whether it is true that owner-operators adopt more effective soil conservation measures than tenant-operators, and whether well-designed agro-environmental instruments can provide sufficiently strong motivation to compensate for the differences between these two groups.
