As an effective land policy that can invigorate rural construction areas and balance urban and rural development, land tickets not only concretely embody the land resource-asset-capitalization process, but also bring economic benefits to the farmers concerned. However, from the perspective of resource-asset-capitalization, the specific environmental impacts and economic costs of the process in land tickets and the changes in the values of ecosystem services need to be considered. This paper uses land tickets in Yanba, Jiangjin, Chongqing as an example, combined with life cycle assessment (LCA), life cycle cost assessment (LCC), and methods for the evaluation of ecosystem services to quantify the environmental load, economic costs, and changes in the value of ecosystem services in the process of land resource-asset-capitalization. Moreover, through this analysis, we attempted to determine the contributions of different environmental indicators and the key links restricting the whole process of land resource-asset-capitalization. On this basis, through a sensitivity analysis, we explored the possibility of reducing environmental impact during the whole process of land resource-asset-capitalization. Through this research, we sought to explore the realization process of land tickets and to enrich the empirical research on land resource-asset-capitalization.

Management Concept

The contradiction between human and land has always been a problem in the process of development and utilization of land resources. Under such circumstances, relevant government agencies put forward the management concept of land resource capitalization. As an effective policy to implement the conception of land resource capitalization, land transfer is of great significance to reforming rural land systems and liberating productivity in poor areas of Tai-hang Mountain in Hebei. However, how to integrate environmental impact and value evaluation of ecosystem services of land transfer in the process of resource capitalization deserves our attention. This paper takes the land transfer of Fuping, Hebei in Tai-hang Mountain as an example, combined with life cycle assessment (LCA), life cycle cost assessment (LCC), and the methods of value evaluation of ecosystem services to quantify the changes of environmental loads, economic costs, and ecosystem services in the whole process and different stages of land resource capitalization. Moreover, through the sensitivity analysis of key environmental indicators, the possibility of restricting environmental costs is explored. This paper studies land transfer from the direction of the cross-discipline and provides a new idea for land resource management.

The Impact

The development of higher education has led to an increasing demand for campus buildings. To promote the sustainable development of campus buildings, this paper combines social willingness-to-pay (WTP) with the analytic hierarchy process (AHP) based on the characteristics of Chinese campus buildings to establish a life cycle assessment–life cycle cost (LCA–LCC) integrated model. Based on this model, this paper analyses the teaching building at a university in North China. The results show that the environmental impacts and economic costs are largest in the operation phase of the life cycle, mainly because of the use of electric energy. The environmental impacts and economic costs during the construction phase mainly come from the building material production process (BMPP); in this process, steel is the main source. Throughout the life cycle, abiotic depletion-fossil fuel potential (ADP fossil) and global warming potential (GWP) are the most prominent indexes. Further analysis shows that these two indexes should be the emphases of similar building assessments in the near future. Finally, this study offers suggestions for the proposed buildings and existing buildings based on the prominent problems found in the case study, with the aim to provide reference for the design, construction, and operation management of similar buildings.

Perceived Impacts

Tourism is a dynamic industry due to changes in the consumer market, and its constant development impacts the host community. Although the adverse outcomes of tourism are not a new phenomenon, new dynamics make this issue of ongoing importance. Governments see the activity primarily as fostering economic development in developing countries with little concern about possible overtourism. This paper aims to identify which indicators influence residents’ perceptions of tourist saturation as an indication of overtourism. These perceptions are examined as a multidimensional construct, comprised of several indicators, namely environmental, cultural, behavioral, public services, benefits, and economic costs. The proposed model is assessed with a sample of 477 residents in coastal destinations of Santa Catarina, Brazil. The results show that the perception of excessive numbers of tourists is increased by environmental indicators, economic costs, and behavioral indicators. These indicators contribute to a greater perception of overtourism. In contrast, the indicators of economic benefits and public services show a negative relationship with the perception of overtourism. This research indicates that when the population realizes the economic benefits and has access to quality public services, the perception of overtourism is lower. The findings contribute to the literature on overtourism in certain destinations.

Bottom Line

Paddy fields emit considerable amounts of methane (CH4), which is a potent greenhouse gas (GHG) and, thereby, causes significant environmental impacts, even as they generate wealth and jobs directly in the agricultural sector, and indirectly in the food-processing sector. Application of biochar in rice production systems will not just help to truncate their carbon footprints, but also add to the bottom-line. In this work, the authors have reviewed the literature on climate change, human health, and economic impacts of using organic residues to make biochar for the addition to croplands especially to rice paddy fields. Biochar-bioenergy systems range in scale from small household cook-stoves to large industrial pyrolysis plants. Biochar can be purveyed in different forms—raw, mineral-enriched, or blended with compost. The review of published environmental life cycle assessment (E-LCA) studies showed biochar has the potential to mitigate the carbon footprint of farming systems through a range of mechanisms. The most important factors are the stabilization of the carbon in the biochar and the generation of recoverable energy from pyrolysis gases produced as co-products with biochar as well as decreased fertiliser requirement and enhanced crop productivity. The quantitative review of E-LCA studies concluded that the carbon footprint of rice produced in biochar-treated soil was estimated to range from −1.43 to 2.79 kg CO2-eq per kg rice grain, implying a significant reduction relative to rice produced without a biochar soil amendment. The suppression of soil-methane emission due to the biochar addition is the dominant process with a negative contribution of 40–70% in the climate change mitigation of rice production. The review of the life cycle cost studies on biochar use as an additive in farmlands demonstrated that biochar application can be an economically-feasible approach in some conditions. Strategies like the subsidization of the initial biochar capital cost and assignment of a non-trivial price for carbon abatement in future pricing mechanisms will enhance the economic benefits for the rice farmers.

High initial costs hinder innovative technologies for building envelopes. Life Cycle Assessment (LCA) should consider energy savings to show relevant economic benefits and potential to reduce energy consumption and CO2 emissions. Life Cycle Cost (LCC) and Life Cycle Energy (LCE) should focus on investment, operation, maintenance, dismantling, disposal, and/or recycling for the building. This study compares the LCC and LCE analysis of Water Flow Glazing (WFG) envelopes with traditional double and triple glazing facades. The assessment considers initial, operational, and disposal costs and energy consumption as well as different energy systems for heating and cooling. Real prototypes have been built in two different locations to record real-world data of yearly operational energy. WFG systems consistently showed a higher initial investment than traditional glazing. The final Life Cycle Cost analysis demonstrates that WFG systems are better over the operation phase only when it is compared with a traditional double-glazing. However, a Life Cycle Energy assessment over 50 years concluded that energy savings between 36% and 66% and CO2 emissions reduction between 30% and 70% could be achieved.

The selection and supply of electric locomotives based on the life cycle contract requires a more thorough review of indicators of their effectiveness implemented in operation. This study examines the main operation indicators currently used: coefficients of operational availability, technical availability, intrinsic availability (instantaneous), availability of the locomotive fleet, performed ton-kilometer operation, and electric power consumption. However, these indicators are not comprehensive and do not provide an overall economic assessment of operation. For a comprehensive assessment of the effectiveness of operation of locomotives, an online calculation of the life cycle cost is proposed. This involves directly using operating and service data for its performance, and the calculation of an indicator — life cycle specific cost (LCSC). The online LCSC is a uniform criterion associated with the energy efficiency of the performed transportation, volume of the ton-kilometer operation, operation expenses, reliability of electric locomotive, and its equipment availability ratio (EAR). The LCSC analysis enables assessment of deviations of the operation effectiveness indicators from those planned, and determining a strategy for improvement of the electric locomotive. It helps to define peculiarities in the operation of an electric locomotive and to forecast its condition and potential properties. Additionally, the LCSC facilitates analyzing the condition of a group of electric locomotives when changing the operation technology (for example, operation starting with increased rolling stock weight), including assessment of the extent of economic benefits of fulfilled measures.Currently, scientists of the JSC “VNIIZhT” and specialists of LLC “Ural Locomotives” are conducting tests on the electric locomotives 2EC6 on the Oktyabrskaya railroad using the “Online LCC” server. This allows online analysis of information collected on the operation and servicing of locomotives under the life cycle contract, pro viding effective and prompt control of the electric locomotive fleet.

Operational Energy

Recent national and international building regulations on the energy performance of buildings focus mainly on the reduction of operational energy. This can be achieved by increasing the energy efficiency of the building, installing highly efficient building service systems and applying renewable energy sources. However, these measures have a price in terms of investment costs, and also in terms of environmental impacts. The life-cycle of building materials, building constructions or whole buildings from cradle to grave can be assessed using the method of Life Cycle Assessment (LCA) and Life Cycle Cost analysis (LCC). These tools take into account not only the heating energy saving due to additional insulation, but also the embodied environmental impacts and costs of the investment. In this paper, the optimum thickness of various insulation materials, including natural and recycled materials is examined considering three main environmental indicators and global costs. The analysis is performed for a typical Hungarian single-family house subject to retrofit.

Irrigation Practices

To address sustainability challenges, agricultural advances in Mediterranean horticultural systems will necessitate a paradigmatic shift toward smart technologies, the impacts of which from a life cycle perspective have to be explored. Using life cycle thinking approaches, this study evaluated the synergistic environmental and economic performance of precise irrigation in greenhouse Zucchini production following a cradle-to-farm gate perspective. A cloud-based decision support system and a sensor-based irrigation management system (both referred to as “smart irrigation” approaches) were analyzed and compared to the farmer’s experience-based irrigation. The potential environmental indicators were quantified using life cycle assessment (LCA) with the ReCiPe 2016 method. For the economic analysis, life cycle costing (LCC) was applied, accounting not only for private product costs but also for so-called “hidden” or “external” environmental costs by monetizing LCA results. Smart irrigation practices exhibited similar performance, consuming on average 38.2% less irrigation water and energy, thus generating environmental benefits ranging from 0.17% to 62%. Single score results indicated that life cycle environmental benefits are up to 13% per ton of product. The cost-benefit analysis results showed that even though the implementation of smart irrigation imposes upfront investment costs, these costs are offset by the benefits to water and energy conservation associated with these practices. The reduction of investment costs and higher water costs in future, and lower internal rate of return can further enhance the profitability of smart irrigation strategies. The overall results of this study highlight that smart and innovative irrigation practices can enhance water-energy efficiency, gaining an economic advantage while also reducing the environmental burdens of greenhouse cultivation in a Mediterranean context.
