The environment of the urban fringe is complex and frangible. With the acceleration of industrialization and urbanization, the urban fringe has become the primary space for urban expansion, and the intense human activities create a high risk of potentially toxic element (PTE) pollution in the soil. In this study, 138 surface soil samples were collected from a region undergoing rapid urbanization and construction—Weinan, China. Concentrations of As, Pb, Cr, Cu, and Ni (Inductively Coupled Plasma Mass Spectrometry, ICP-MS) and Hg (Atomic Fluorescence Spectrometry, AFS) were measured.
Soil Quality Assessment Using Multivariate Approaches: A Case Study of the Dakhla Oasis Arid Lands
A precise evaluation of soil quality (SQ) is important for sustainable land use planning. This study was conducted to assess soil quality using multivariate approaches. An assessment of SQ was carried out in an area of Dakhla Oasis using two methods of indicator selection, i.e., total data set (TDS) and minimum data set (MDS), and three soil quality indices (SQIs), i.e., additive quality index (AQI), weighted quality index (WQI), and Nemoro quality index (NQI). Fifty-five soil profiles were dug and samples were collected and analyzed.
Fit-For-Purpose Upscaling Land Administration—A Case Study from Benin
The government of Benin in 2013 decided upon a centralized land administration, with the purpose of recording the entire national territory in one land administration system to promote durable economic development by increasing legal certainty in real estate transactions. This is a major challenge, given that currently, of the estimated 5 million cadastral parcels, less than 60,000 parcels have a land title and are registered in the national land administration agency’s central database.
Does Farmland Scale Management Promote Rural Collective Action? An Empirical Study of Canal Irrigation Systems in China
Farmland scale management represents an inevitable trend toward global modern agriculture. In the new development context, the key to solving the tough problem of the insufficient supply of rural public goods is to effectively improve the enthusiasm of farming households to participate in rural collective action in countries with a small arable area per capita, such as India, China and countries in Eastern Europe.
Transforming Land Administration Practices through the Application of Fit-For-Purpose Technologies: Country Case Studies in Africa
Access to land for many people in Africa is insecure and continues to pose risks to poverty, hunger, forced evictions, and social conflicts. The delivery of land tenure in many cases has not been adequately addressed. Fit-for-purpose spatial frameworks need to be adapted to the context of a country based on simple, affordable, and incremental solutions toward addressing these challenges. This paper looked at three case studies on the use of the Social Tenure Domain Model (STDM) tool in promoting the development of a fit-for-purpose land administration spatial framework.
