Triggers of Delays in International Projects Using Engineering Procurement and Construction Delivery Methods in the Belt and Road Initiative: Case Study of a High-Speed Railway Projects

Peer-reviewed publication
Diciembre, 2020
Global

Since the Belt and Road Initiative (BRI) has been put in practice by the Chinese government, several High-Speed Railways (HSR) have been built by Chinese Engineering Procurement and Construction (EPC) firms. However, many delays have created severe detrimental consequences on the progress of most HSR projects. This study sought to explore the essence of the recurring triggers of delays in international EPC HSR projects under the BRI, and a structured questionnaire survey approach was applied to compile the first-hand dataset from Chinese EPC firms working for BRI infrastructure projects.

Financial Analysis of Habitat Conservation Banking in California

Peer-reviewed publication
Diciembre, 2020
United States of America

Habitat conservation banking is a policy instrument for conserving endangered species by providing financial incentives for the landowners in the United States. This policy instrument aims to protect habitat, but little or no thought has been given to its financial performance. A financial analysis of habitat conservation banks (HCB) informs policymakers and conservation biologists of the long-term success of this policy and the future of HCBs. This paper evaluates 26 habitat conservation banks (HCB) in California by calculating their Net Present Values (NPV).

The Agrarian, Structural and Cultural Constraints of Smallholders’ Readiness for Sustainability Standards Implementation: The Case of Indonesian Sustainable Palm Oil in East Kalimantan

Peer-reviewed publication
Diciembre, 2020
Indonesia

The expansion of oil palm plantation has caused adverse impacts on the ecosystem. It has been associated with deforestation, biodiversity loss, disturbances to environmental services and livelihood change. The government of Indonesia has made an effort to control the negative effects by issuing relevant policies. One of the policies is Indonesian Sustainable Palm Oil (ISPO)’s sustainability standards to which large-scale plantations and smallholders are obliged to adhere.

A Comparative Analysis of Spatial Data and Land Use/Land Cover Classification in Urbanized Areas and Areas Subjected to Anthropogenic Pressure for the Example of Poland

Peer-reviewed publication
Diciembre, 2020
Global

Urbanization processes are some of the key drivers of spatial changes which shape and influence land use and land cover. The aim of sustainable land use policies is to preserve and manage existing resources for present and future generations. Increasing access to information about land use and land cover has led to the emergence of new sources of data and various classification systems for evaluating land use and spatial changes.

Digital Plan of Brickwork Layout for Robotic Bricklaying Technology

Peer-reviewed publication
Diciembre, 2020
Global

The trend of using modern technologies in the construction industry has been growing stronger recently, particularly in the fields of additive construction or robotic bricklaying. Therefore, specifically for the purpose of robotic bricklaying, we created a digital layout plan for robotic construction works. This article presents a universal methodology for creating a bricklaying plan for various variations of wall building systems.

Land and Sea Coordination: Revisiting Integrated Coastal Management in the Context of Community Interests

Peer-reviewed publication
Diciembre, 2020
Global

At present, the ecological environment and resources of the global coastal zones are facing great pressures. Climate change leads to sea level rise, environmental change, stressful population increases and changes in demographics, all of which affect existing coastal management systems. Therefore, all coastal countries begin to increasingly attach importance to the integrated management of coastal zones. How to better adapt to current changes in global coastal zones is a question that every coastal country should think about.

Climate Change Impacts on Rice Cultivation: A Comparative Study of the Tonle Sap and Mekong River

Peer-reviewed publication
Diciembre, 2020
Global

Climate change is unequivocal. Farmers are increasingly vulnerable to floods and drought. In this article, the negative impact of climate hazards on rice cultivation in the Tonle Sap and Mekong River influenced by climatic variability between 1994 and 2018 are analyzed. A cohort of 536 households from four Cambodian districts participated in household surveys designed to consider how various vulnerability factors interacted across this time series.

MgO-Based Cementitious Composites for Sustainable and Energy Efficient Building Design

Peer-reviewed publication
Diciembre, 2020
Global

Concrete made with Portland cement is by far the most heavily used construction material in the world today. Its success stems from the fact that it is relatively inexpensive yet highly versatile and functional and is made from widely available raw materials. However, in many environments, concrete structures gradually deteriorate over time. Premature deterioration of concrete is a major problem worldwide. Moreover, cement production is energy-intensive and releases a lot of CO2; this is compounded by its ever-increasing demand, particularly in developing countries.

Evaluation of Land Use and Land Cover Change and Its Drivers in Battambang Province, Cambodia from 1998 to 2018

Peer-reviewed publication
Diciembre, 2020
Cambodia

The main objective of this research was to evaluate land use and land cover (LULC) change in Battambang province of Cambodia over the last two decades. The LULC maps for 1998, 2003, 2008, 2013 and 2018 were produced from Landsat satellite imagery using the supervised classification technique with the maximum likelihood algorithm. Each map consisted of seven LULC classes: built-up area, water feature, grassland, shrubland, agricultural land, barren land and forest cover.

Social Sustainability and Ulaanbaatar’s ‘Ger Districts’: Access and Mobility Issues and Opportunities

Peer-reviewed publication
Diciembre, 2020
Mongolia

This paper explores the concept of social sustainability in Ulaanbaatar’s ger districts in relation to access and mobility. Although ger districts are well-established in Mongolian culture as ephemeral encampments with transient residents, contemporary ger districts have become large and permanent residential districts that are now home to an estimated one-third of the country’s population.

Varieties Matter When Planning for Poverty Alleviation and Ecological Restoration in Karst Fruit Cultivation Areas

Peer-reviewed publication
Diciembre, 2020
Global

Landscapes are increasingly being managed to meet multiple objectives and balance social, economic, and environmental goals. The Honghe Hani and Yi Autonomous Prefecture in the Yunnan faulted Basin represent examples of areas with a range of concerns, including balancing farming with poverty alleviation, economic development, and ecological protection. Here, we set out four future land-use scenarios to quantify and map the values of key evidence-based, policy-relevant ecosystem services in three typical counties in this area.
