Spatial Structure of a Potential Ecological Network in Nanping, China, Based on Ecosystem Service Functions

Peer-reviewed publication
September, 2020
United States of America
China
Russia

The increasing scale of urbanization and human activities has resulted in the fragmentation of natural habitats, leading to the reduction of ecological landscape connectivity and biodiversity. Taking Nanping as the study area, the core areas with good connectivity were extracted as ecological sources using a morphological spatial pattern analysis (MSPA) and landscape connectivity index. Then the ecosystem service functions of the ecological sources were evaluated based on the InVEST model.

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
September, 2020
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).

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

Peer-reviewed publication
September, 2020
Southern Africa
South Africa
Turks and Caicos Islands

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.

Transformation of Industrial Land in Urban Renewal in Shenzhen, China

Peer-reviewed publication
September, 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.

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
September, 2020
Iran

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.

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

Peer-reviewed publication
September, 2020
China
United Kingdom

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.

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

Peer-reviewed publication
September, 2020
Belize
Bolivia
Guyana
Suriname
United States of America

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
September, 2020
Peru

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.

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

Peer-reviewed publication
September, 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.

Could Mapping Initiatives Catalyze the Interpretation of Customary Land Rights in Ways that Secure Women’s Land Rights?

Peer-reviewed publication
September, 2020
Sub-Saharan Africa

Although land forms the basis for marginal livelihoods in Sub-Saharan Africa, the asset is more strategic for women as they usually hold derived and dependent rights to land in customary tenure areas. Initiatives to secure women’s land tenure in customary areas are undermined by the social embeddedness of the rights, patriarchy, lack of awareness by the communities, legal pluralism, and challenges of recording the rights.
