In this paper, a GPU-accelerated Cholesky decomposition technique and a coupled anisotropic random field are suggested for use in the modeling of diversion tunnels. Combining the advantages of GPU and CPU processing with MATLAB programming control yields the most efficient method for creating large numerical model random fields. Based on the geological structural characteristics of red-bedded soft rocks in central Yunnan, anisotropic rock random fields and tunnel excavation with various rotation degrees are simulated.

The last century has witnessed European commercial aviation flourishing at the cost of environmental degradation by boosting greenhouse gas and CO2 emissions in the atmosphere. However, the outcry for net-zero emissions compels the sector’s supply chain to a minimum 55% reduction of greenhouse gas emissions below the 1990 level by 2030 and zero CO2 emissions by 2050. This study examines a European environmental sustainability path toward a green commercial aviation supply chain.

Context and background There is a reciprocal relationship between theory, policy and practice. Property valuation as practiced today is elucidated by certain standards and policies which are based on theoretical foundations. The axioms of value have been postulated throughout history, from pre-classical times to the present, with succeeding theorists, some adopting the former’s reason with adjustments and some refuting.

This paper sets out why land expropriation is a hidden danger of the response to climate change; a danger that is not adequately captured in legislation and that risks disproportionately affecting the poor. Measures to mitigate the risks and impacts of climate change are often dependent on states’ access to land.

En République Centrafricaine, l’Etat détient le pouvoir d’exproprier une personne physique ou morale d’un bien foncier. Cette pratique se justifie par la mise en œuvre des Projets d’Intérêt Général dont l’Etat seul est garant. La corruption n’est pas absente dans le mécanisme. L’objectif de cette étude consiste à analyser les procédures d’expropriation pour cause d’utilité publique en Centrafrique et relever les cas de corruption quand il s’agit d’indemniser les victimes. Les méthodes analytique et descriptive ont été utilisées pour la réalisation de ce travail.

The ongoing use of landscape-based conflict commodities — diamonds and other minerals, timber, wildlife, etc. — to finance wars continues to evolve. The success with which such commodities can be transacted to support militaries, militias and insurgencies has led belligerents to innovate with additional commodities. Housing, land and property (HLP) rights within war zones have belatedly joined the list of conflict commodities that are subject to transaction, and to such an extent as to warrant significant concern.

Through a collaborative process with the Land Law Advisory Group in Laos, this series of briefing notes addresses some of the most pressing issues in the country in relation to the recently passed Land Law (2019) and Forest Law (2019). The five briefs in the series address: tenure rights in state forestlands; customary tenure rights; tenure rights to land for collective purposes; awareness-raising for gender and social inclusive and safeguards in cases of land loss or expropriation.

In the context of China’s new round of land reform, narrowing the scope of land expropriation, standardising the procedures for land expropriation, and building a unified urban and rural construction land market have become the objectives of land expropriation reform. The new Land Management Law of the People’s Republic of China confirms land expropriation for tract development as a new situation for the land acquisition system.

The transfer of urban development goals from two-dimensional land to three-dimensional space leads to the dilemmas of the functional adjustment of partial space in the building, such as an unclear property right system, vague land financial expropriation method, uncertain economic value, etc. This study aims to understand land-development-right pricing based on spatial characteristics in spatial function regeneration. Especially, we deal with the following questions: (1) How do we identify the spatial development rights and their pricing?

Compensation for land expropriation due to development projects such as mining is shifting from cash to physical assets like housing. Therefore, empirical studies are required to assess the residential satisfaction of project-affected families (PAFs) living in these houses and the factors which can enhance their satisfaction and quality of life in the long term. This study, therefore, assesses the antecedents of PAFs’ satisfaction with their current residence as an outcome of a mining-induced displacement and resettlement (MIDR) in Ellembelle, Ghana.

In Italy, an increasing number of historical buildings have been abandoned in the last decades. As a response, some local administrations decided to foster renovation projects to preserve their heritage for future generations. Among them, the northern municipality of Val di Zoldo (Veneto) relies on the European Shelter Project, which covers a part of the costs of renovating an ancient private barn called Mas di Sabe, which the community considers an identity symbol of local history and culture.

In the current context of rapid global urbanization, China’s urbanization is also accelerating, and the rational planning and sustainable use of state land and space have become a growing concern. The expansion of urban geographic space is inevitably accompanied by the massive expropriation of rural land.
