A Comparison of Approaches to Regional Land-Use Capability Analysis for Agricultural Land-Planning

Peer-reviewed publication
Décembre, 2020
Niger

Smallholder agriculture is a major source of income and food for developing nations. With more frequent drought and increasing scarcity of arable land, more accurate land-use planning tools are needed to allocate land resources to support regional agricultural activity. To address this need, we created Land Capability Classification (LCC) system maps using data from two digital soil maps, which were compared with measurements from 1305 field sites in the Dosso region of Niger. Based on these, we developed 250 m gridded maps of LCC values across the region.

Assessing Matching Characteristics and Spatial Differences between Supply and Demand of Ecosystem Services: A Case Study in Hangzhou, China

Peer-reviewed publication
Décembre, 2020
China

Ecosystem services (ESs) is a term used to describe the foundations of the well-being of human society, and several relevant studies have been carried out in this area. However, given the fact that the complex trade-offs/synergy relationships of ESs are a challenging area, studies on matching mechanisms for ES supply and demand are still rare.

Agricultural Land Transition in the “Groundnut Basin” of Senegal: 2009 to 2018

Peer-reviewed publication
Décembre, 2020
Senegal

The study aims to reveal the transition features of agricultural land use in the Groundnut Basin of Senegal from 2009 to 2018, especially the impact of urbanization on agricultural land and the viewpoint of farmland spatiotemporal evolution. Integrated data of time series MCD12Q1 land-use images of 2009, 2012, 2015, and 2018 were used to provide a land transition in agricultural and urban areas through the synergistic methodology. Socio-economic data was also used to serve as a basis for the argument.

Identification of Potential Land-Use Conflicts between Agricultural and Ecological Space in an Ecologically Fragile Area of Southeastern China

Peer-reviewed publication
Décembre, 2020
China

In the context of ensuring national food security, high-intensity agricultural production and construction activities have aggravated the conflicts between agricultural and ecological spaces in ecologically fragile areas, which have become one of the most important factors hindering regional sustainable development. This study took Lin’an District, a typical hilly region of southeastern China, as an example.

The Spatial Changes of Transportation Infrastructure and Its Threshold Effects on Urban Land Use Efficiency: Evidence from China

Peer-reviewed publication
Décembre, 2020
China

The development of social production and the agglomeration of the urban population have brought tremendous pressure to transportation infrastructure. However, the impacts of transportation development on urban land use systems have not been well investigated. Under the pressure of limited land resources, the impact of transportation infrastructure on urban land use efficiency (ULUE) is receiving increasing attention from scholars and needs to be explored.

Ecosystem Services Changes on Farmland in Response to Urbanization in the Guangdong–Hong Kong–Macao Greater Bay Area of China

Peer-reviewed publication
Décembre, 2020
China

Extensive urbanization around the world has caused a great loss of farmland, which significantly impacts the ecosystem services provided by farmland. This study investigated the farmland loss due to urbanization in the Guangdong–Hong Kong–Macao Greater Bay Area (GBA) of China from 1980 to 2018 based on multiperiod datasets from the Land Use and Land Cover of China databases. Then, we calculated ecosystem service values (ESVs) of farmland using valuation methods to estimate the ecosystem service variations caused by urbanization in the study area.

Study on the Spatial Classification of Construction Land Types in Chinese Cities: A Case Study in Zhejiang Province

Peer-reviewed publication
Décembre, 2020
Global

Identifying the land-use type and spatial distribution of urban construction land is the basis of studying the degree of exposure and the economic value of disaster-affected bodies, which are of great significance for disaster risk predictions, emergency disaster reductions, and asset allocations. Based on point of interest (POI) data, this study adopts POI spatialization and the density-based spatial clustering of applications with noise (DBSCAN) algorithm to accomplish the spatial classification of construction land.

How to Perceive the Trade-Off of Economic and Ecological Intensity of Land Use in a City? A Functional Zones-Based Case Study of Tangshan, China

Peer-reviewed publication
Décembre, 2020
China

China, in a rapid urbanization process, is accompanied by the expansion of built-up land, population accumulation, and intensive land investment, while the improvement of the urban environment cannot keep up with the population and economic density growth. Therefore, the purpose of this paper is to discuss the balance between urban land use economic intensity (built-up area density, population density, land price) and ecological intensity (the depth, breadth, and integration of ecological spaces) in Tangshan.

Value Capture and Vertical Allocations of Public Amenities

Peer-reviewed publication
Décembre, 2020
Israel

This paper describes and critically reviews an important but under-theorized value capture mechanism that we have termed “vertical allocations” (or vertical exactions). This mechanism enables cities to capture value vertically by allocating floor space for public utilities in privately owned, mixed-use, vertical development. As a value capture tool, vertical allocations allow the government to tap value uplift to supply the nearby neighborhood, and the city as a whole, with much needed public services.

Impacts of Agricultural Land Acquisition for Urbanization on Agricultural Activities of Affected Households: A Case Study in Huong Thuy Town, Thua Thien Hue Province, Vietnam

Peer-reviewed publication
Décembre, 2020
Global

Agricultural land acquisition for urbanization (ALAFU) has strongly impacted agriculture in Vietnam during the last decades. Given the mixed data obtained from a survey (with 50 households who lost 50% of their farmland area), in-depth interviews, a group-focused discussion and observation, this study shows the different impacts of ALAFU on each agricultural activity of affected household by comparing before and after ALAFU. Rice cultivation and animal breeding have sharply declined, but potted flower plantation (PFP) has quickly grown and is the main income of 34% of surveyed households.

The Marketization of Rural Collective Construction Land in Northeastern China: The Mechanism Exploration

Peer-reviewed publication
Décembre, 2020
China

The transfer of rural collective construction land into the market (RCCL marketization) is an important starting point for breaking the urban–rural dual system, realizing the sustainable use of land resources and promoting the integrated development of urban and rural areas in China. This study aims to explore the decision-making of rural households in the marketization of rural collective construction land (RCCL) by constructing a two-stage (cognition-decision) theoretical framework.

Urban Plans and Conflicting Interests in Sustainable Cross-Boundary Land Governance, the Case of National Urban and Regional Plans in Ethiopia

Peer-reviewed publication
Décembre, 2020
Ethiopia

Policies and rules by which land is governed are influenced by political discourses, and decisions about land can provoke political conflicts. In contexts of vague legal framework governing property right, planning tends to produce inequality and could be observed as a political instrument of marginalization. Nevertheless, spatial planning is indispensable for ensuring sustainable and efficient land governance. In Ethiopia, urban planning is considered unjust, often associated with eviction of rural and urban residents.
