Displaying 126 - 130 of 498Land Registry Framework Based on Self-Sovereign Identity (SSI) for Environmental Sustainability
Providing a system user with a unique and secure identity is a prerequisite for authentication and authorization aspects of a security system. It is generally understood that the existing digital identity systems store the identity details in centralized databases, and users store the identity details in centralized databases in which users do not have any control over them. These vulnerabilities in the traditional digital identities make them susceptible to various malicious assaults and modifications.
Impact of Confirmation of Farmland Rights on Farmers’ Welfare: Based on the Micro-Empirical Investigation of Farmers in China
The confirmation of farmland rights would have a great impact on the welfare of farmers in China. Taking Chinese farmers as the research object, the relationship between farmland rights confirmation, farmland transfer and the welfare of farmers was studied by adopting the propensity score matching method (PSM) and logistic model. The result showed that: (1) The confirmation of farmland rights could improve the welfare of farmers.
The Impact of Farmland Tenure Security on China’s Agricultural Production Efficiency: A Perspective of Agricultural Production Factors
Improving agricultural production efficiency is an effective means to ensure food security and promote agricultural sustainable development in China. Stable agricultural land property rights help optimize the allocation of production factors and improve production efficiency, and it is of great practical significance to study the influence of farmland tenure security on agricultural production efficiency.
Spatial Efficiency and Socioeconomic Efficiency in Urban Land Policy and Value Capturing: Two Sides of the Same Coin?
Land policies are commonly used to contribute to the implementation of the public policy of land-use planning (or spatial planning). In this sense, a spatially efficient land policy must allow the planning systems to achieve the land uses promoted by strategic planning. In addition to their role in land-use planning, land policies also contribute to public finance policies. From this perspective, a socioeconomically efficient land policy must allow public authorities to capture land value.
Extraction of Rural Residential Land from Very-High Resolution UAV Images Using a Novel Semantic Segmentation Framework
Accurate recognition and extraction of rural residential land (RRL) is significant for scientific planning, utilization, and management of rural land. Very-High Resolution (VHR) Unmanned Aerial Vehicle (UAV) images and deep learning techniques can provide data and methodological support for the target. However, RRL, as a complex land use assemblage, exhibits features of different scales under VHR images, as well as the presence of complex impervious layers and backgrounds such as natural surfaces and tree shadows in rural areas.
