Following a regional-level study conducted in Fukushima Prefecture, Japan (Wang et al., 2014 [1]), this paper presents an approach for municipal renewable energy planning and its experimental application in a Japanese municipality using a Geographic Information System (GIS). The proposed approach is comprised of local issue identification, renewable energy potential evaluation and visualization, site comparison and scenario analysis. GIS was used to analyze and visualize solar, wind and biomass (forest and agriculture residue) potential within Kawamata Town, Fukushima, Japan. According to local conditions, all potential sites were coded and then compared based on different criteria, such as solar radiation, wind speed, slope and land uses, among others. In the scenario analysis section, two scenarios, “renewable energy prioritized” and ”evacuation area prioritized”, were adopted and compared. The scenarios are altered in terms of placement and the number of renewable energy facilities inside and outside evacuation areas within the town. The results generated through the proposed approach can provide information on local potentials of renewable energy resources, as well as renewable energy development alternatives at the municipal level. They can be used in the interactive dialogue for the municipal renewable energy planning process, to help to fulfill the municipality’s post-earthquake energy developmental vision. Full article

A study was conducted to determine the efficacy of applying ground magnesium limestone (GML) or ground basalt in combination with bio-fertilizer to sustain rice production on an acid sulfate soil in Malaysia. Soils from Kelantan Plains, Malaysia, were treated with GML, ground basalt, bio-fertilizer, GML + bio-fertilizer, and ground basalt + bio-fertilizer (4 t·ha⁻¹ each). Results showed that soil fertility was improved by applying the soil amendments. GML and basalt contain some Zn and Cu; thus, application of these amendments would increase their contents in the soil needed for the healthy growth of rice. Basalt applied in combination with bio-fertilizer appeared to be the best agronomic option to improve the fertility of acid sulfate soils for sustainable rice production in the long run. In addition to increasing Ca, Mg, Zn, and Cu reserves in the soil, water pH increased and precipitated Al³⁺ and/or Fe²⁺. Ground basalt is cheaper than GML, but basalt dissolution in the acidic soil was slow. As such, its ameliorative effects could only be seen significantly from the second season onwards. The specially-formulated bio-fertilizer for alleviating the infertility of acid sulfate soil could also enhance rice growth. The use of the bio-fertilizer fortified with N₂-fixing bacteria is a green technology that would help reduce NO₃⁻ and/or NO₂⁻ pollution and reduce the cost of rice production. The phosphate-solubilizing bacteria (PSB) present in the bio-fertilizer not only increased the available P, but also helped release organic acids that would inactivate Al³⁺ and/or Fe²⁺ via the process of chelation.

In the face of climate change, scholars and policymakers are increasingly concerned with fostering “urban resilience”. This paper seeks to contribute towards a better understanding of synergies and differences in how academics and local decision-makers think about resilience in the context of climate change. We compare definitions and characteristics of urban climate resilience in the academic literature with a survey of 134 local government representatives from across the U.S. Our analysis shows discrepancies in how academics and practitioners define and characterize urban climate resilience, most notably in their focus on either “bouncing back” or “bouncing forward” after a disturbance. Practitioners have diverse understandings of the concept, but tend to favor potentially problematic “bouncing back” or engineering-based definitions of resilience. While local government respondents confirm the importance of all 16 resilience characteristics we identified in the academic literature, coding practitioners’ free response definitions reveals that they rarely mention qualities commonly associated with resilience in the scholarly literature such as diversity, flexibility, and redundancy. These inconsistencies need to be resolved to ensure both the usability of climate resilience research and the effectiveness of resilience policy. Full article

The study aims to contribute to the literature by empirically examining the relationship between small and medium sized enterprises’ (SMEs) mission statements and their performance in sustainable strategy formulation. Although it seems that there is a relatively vast amount of research with regard to mission statements of companies, very few studies have focused on the relationship between mission statements and performance. When these few studies are taken into consideration, it is difficult to reach any overall conclusion since their findings are mixed and inconclusive. To achieve this aim, 3034 SMEs operating in organized industrial zones in Turkey were examined via a survey approach. In order to investigate the relationships among the variables, nine categories of mission statements as independent variables and four performance indicators (financial, market, production, and overall) as dependent variables were analyzed through logistic regression. This study identified three mission components, (1) survival, growth, and profit; (2) philosophy and values; and (3) public image, as the common independent variables in explaining the performance of SMEs. Survival, growth, and profit is the most frequently observed mission component regardless of the subsector differentiation in the entire sample, which reflects the significance of business sustainability for SMEs in the Turkish manufacturing context. Besides, among all performance indicators, SMEs’ market performance was found to be the lowest when compared to other performance indicators (financial, production, overall). Although the firms were placed in different manufacturing subsectors, similar mission statements were highlighted so that the discourse similarity might be considered as evidence of isomorphism characteristics for SMEs.

This paper examines small hotels that have some type of environmental certification. A survey of 210 small (less than 50 employees) Catalonian hotels was conducted to investigate whether there are significant differences in the results of the implementation practices between hotels that adopt these certifications due to environmental pressure (from the government, customers, suppliers and other stakeholders) and hotels that voluntarily commit to green policies. Significant differences were identified in the results on the hotels when structural equation modelling (SEM) was undertaken. This investigation suggests that hotels that voluntarily commit to green policies obtain better results than other hotels. The conclusion is that governments must not only regulate, but also promote awareness actions in small and medium-sized (SME) tourism companies to improve the environment. SME tourism companies must understand that both the environment and they themselves will benefit. Full article

The electricity industry is a basic industry of the national economy. It has experienced several large-scale power shortages, hard power shortage and soft power shortage, which have brought a great threat to China’s sustainable economic development. To solve this problem better, it is necessary to make a quantitative assessment of the economic impacts of power shortage. The CGE model is commonly used for simulating economic shocks and policy effects. It describes supply, demand and equilibrium in different markets by simulating the economic mechanism through a set of equations. Once changed, the exogenous variables will affect a certain part of the system and then the whole system, leading to changes in quantities and prices. The equilibrium state will also change from one to another. A static CGE model is built in this paper, and the Social Accounting Matrix (SAM) of eight sectors of China in 2007 is compiled, in order to simulate the economic impacts of hard power shortage and soft power shortage. Simulation results show that the negative effects of power shortage on economic development are very significant, and the effects vary in different sectors. Especially, under the background of hard power shortage, the industrial sector suffers most. The economic cost of power shortage is considerable, and the main reason for it is the specific administrative pricing system in China. The low electricity price in the long term will lead to insufficient construction and hard power shortage; moreover, that in the short run would result in soft power shortage. In order to solve the problem of power shortage completely, power system reform is inevitable. Full article

As the main source of CO₂ emissions in China, the industrial sector has faced pressure for reducing emissions. To achieve the target of 50% reduction of industrial carbon intensity by 2020 based on the 2005 level, it is urgent to formulate specific CO₂ emission mitigation strategies in the provincial industrial sector. In order to provide decision-making support for the development and implementation of mitigation policy, our undesirable slack based measure (SBM) model is firstly applied to evaluate the industrial CO₂ emission efficiency under total-factor frame (TFICEE) in 13 prefecture-level cities of Jiangsu Province, the largest CO₂ emitter in China. Then, we analyze space-time distribution and distributional evolution tendency of TFICEE by using the GIS visualization method and kernel density estimation, respectively. Finally, we utilize the industrial abatement model to estimate the CO₂ abatement potential of Jiangsu’s industrial sector. The empirical results show that there exists a significant spatial inequality of TFICEE across various regions in Jiangsu, but the regional disparity has been narrowing during our study period. Additionally, average annual industrial CO₂ emission reductions in Jiangsu Province can attain 15,654.00 (ten thousand tons), accounting for 28.2% of its average annual actual emissions, which can be achieved by improving production technology, adjusting industrial structure and raising the level of industry concentration.

Quantitative measures of transport disadvantage are reviewed in this paper from the perspective of their effectiveness to investigate social exclusion. The effectiveness is assessed using criteria derived through a review of the concepts of transport disadvantage and social exclusion and their operationalisation. The specified criteria are related to issues of spatial (e.g., urban accessibility, and public transport accessibility), temporal (e.g., public transport availability, and facility opening hours), and social attributes of travel and activity participation (e.g., personal mobility, and disability). Four groups of transport disadvantage measures are identified and evaluated. These include deprivation-based measures, mobility-based measures, accessibility-based measures, and activity-based measures. The review suggests that although the first three categories of measures have traditionally been used to identify transport disadvantage, they do not satisfy issues surrounding activity participation—the key outcome of social exclusion. The activity space concept is a way in which these issues can be incorporated, as it is a measure of the outcomes of activity participation and their associated travel to that activity. Participation in an activity means that an individual has overcome the spatial, temporal and social barriers of travel for that activity. The research using the activity space concept has, however, inadequately identified individual travel and activity participation. This has been due to a separate application of a range of different indicators to assess activity space size. These indicators are by their nature multidimensional—e.g., area visited, distance travelled, and number of activity sites visited. Although each indicator represents a specific qualitative/quantitative aspect of travel and activity participation, researchers have treated these indicators in an isolated manner to identify transport disadvantage and consequently transport-related social exclusion. This paper identifies the weaknesses and strengths associated with these measures; and methods are directed to overcome the limitations. Full article

Building on longitudinal data from 73 Chinese manufacturing firms during 2009–2012, we assess whether and how firms gain higher efficiency in achieving their sustainability goals by adopting management practice standards (ISO 9001, ISO 14001, and/or OHSAS 18001). We propose four pathways for firms to gain sustainability efficiency in their certification journey: participation, qualitative integration, quantitative expansion, and temporal accumulation. Our results confirm that firms certifying management standards gain higher efficiency in pursuing their sustainability goals than firms without these standards. We also find some support for increased efficiency effect in firms with diverse management systems over firms with only a single certificate in 2011. Finally, our results highlight the experiential and temporal accumulation effect of such efficiency gains, that is, firms with prior certification experience or having a longer certification history demonstrate higher efficiency gains in pursuing their sustainability goals.

Future challenges to the global food supply chain are complex. In order to embrace sustainability, companies should change their management practices towards more efficient resource use. Food waste being a misuse of resources, we identify its causes and possible ways of minimising it. To achieve this goal, we conducted explorative research with qualitative and quantitative data through in-depth semi-structured interviews and an open questionnaire with top Spanish food service companies. Results show that most businesses mainly tend to minimise food waste according to economic criteria, without taking into account the social, ethical or environmental factors. As a consequence, just “visible” food waste that has an economic impact on the results is minimised. Nevertheless, visibility of real waste is often low. At the same time, awareness of (and therefore initiatives to reduce) food waste that does not directly affect a firm’s profit can be increased through multi-stakeholder collaboration. Opportunities for reducing food waste therefore arise from increasing the visibility of food that is discarded as well as addressing plate waste. We identify best practices that could lead to a reduction of the amount of food waste generated in the out of home channel in Spain. Full article

Traffic noise is a combination of noises produced from a number of sources. Of all the traffic noise sources, tire-pavement noise, which is emitted as a result of the interaction of rolling, slipping, or dragging tires and the pavement surface, is the dominant contributor of overall noise, particularly when vehicles are moving at higher speeds. Therefore, a number of research studies have been conducted to identify and analyze the factors affecting the generation of tire-pavement interaction noise. This helps in identifying and selecting appropriate noise mitigation techniques. In this paper, an extensive literature survey on the factors affecting tire-pavement noise is presented, and different views on the impact of each individual factor are discussed. From the literature survey, it is also evident that there is a potential correlation between pavement’s material characteristics and tire-pavement noise. A comprehensive discussion about this correlation is presented in the paper. In addition, this paper discusses various mathematical models for predicting pavement noise, and their advantages and shortcomings. Full article

Sustainable use of natural resources in the production of construction materials has become a necessity both in Europe and Turkey. Construction products in Europe should have European Conformity (CE) and Environmental Product Declaration (EPD), an independently verified and registered document in line with the European standard EN 15804. An EPD certificate can be created by performing a Life Cycle Assessment (LCA) study. In this particular work, an LCA study was carried out for a refractory brick production for environmental assessment. In addition to the LCA, the Life Cycle Cost (LCC) analysis was also applied for economic assessment. Firstly, a cradle-to-gate LCA was performed for one ton of magnesia spinel refractory brick. The CML IA method included in the licensed SimaPro 8.0.1 software was chosen to calculate impact categories (namely, abiotic depletion, global warming potential, acidification potential, eutrophication potential, human toxicity, ecotoxicity, ozone depletion potential, and photochemical oxidation potential). The LCC analysis was performed by developing a cost model for internal and external cost categories within the software. The results were supported by a sensitivity analysis. According to the results, the production of raw materials and the firing process in the magnesia spinel brick production were found to have several negative effects on the environment and were costly.

Significant potential for reducing thermal energy consumption in buildings of moderate and cold climate countries lies within wind energy utilisation. Unlike solar irradiation, character of wind speeds in Central and Northern Europe correspond to the actual thermal energy demand in buildings. However, mechanical wind energy undergoes transformation into electrical energy before being actually used as thermal energy in most wind energy applications. The study presented in this paper deals with hydraulic systems, designed for small-scale applications to eliminate the intermediate energy transformation as it converts mechanical wind energy into heat directly. The prototype unit containing a pump, flow control valve, oil tank and piping was developed and tested under laboratory conditions. Results of the experiments showed that the prototype system is highly efficient and adjustable to a broad wind velocity range by modifying the definite hydraulic system resistance. Development of such small-scale replicable units has the potential to promote “bottom-up” solutions for the transition to a zero carbon society. Full article

The notion of the bioeconomy has gained importance in both research and policy debates over the last decade, and is frequently argued to be a key part of the solution to multiple grand challenges. Despite this, there seems to be little consensus concerning what bioeconomy actually implies. Consequently, this paper seeks to enhance our understanding of what the notion of bioeconomy means by exploring the origins, uptake, and contents of the term “bioeconomy” in the academic literature. Firstly, we perform a bibliometric analysis that highlights that the bioeconomy research community is still rather fragmented and distributed across many different fields of science, even if natural and engineering sciences take up the most central role. Secondly, we carry out a literature review that identifies three visions of the bioeconomy. The bio-technology vision emphasises the importance of bio-technology research and application and commercialisation of bio-technology in different sectors of the economy. The bio-resource vision focuses on processing and upgrading of biological raw materials, as well as on the establishment of new value chains. Finally, the bio-ecology vision highlights sustainability and ecological processes that optimise the use of energy and nutrients, promote biodiversity, and avoid monocultures and soil degradation.

Localisation may be used as a strategy to remedy the harmful socio-ecological impacts of economic globalisation, and lead to improved sustainability achievements. This article describes the formation of a regional-level localisation index for the 20 districts of Bhutan, demonstrating a way to identify localised places using regionally specific data. Secondary source data were gathered in Bhutan according to localisation expert-identified metrics, which were then weighted, standardised, scored and ranked. This enabled the formation of a Bhutanese regional-level localisation index. The index may assist those seeking regional-level localisation case studies by enabling the identification of localised places in Bhutan. The article also summarises sustainability-planning interviews carried out across Bhutan to determine causal factors relating to localisation scores, in particular focusing on the top localisation-scoring district, Dagana. The interviews revealed that Bhutan is a highly localised country that has long and intentionally planned many aspects of localisation. Full article

The regional growth of the goods and services trade has placed greater pressure on the ports of the Asia-Pacific Economic Cooperation (APEC) members, especially in the developing countries. The purpose of this study is to apply the generalized metafrontier Malmquist productivity index (gMMPI) to compare the port productivity of developed countries (DCs) and developing countries (LDCs) in APEC. The results indicate that, first, the average rate of utilized capacity among the ports of APEC members was only 65.7% during 2002–2011, which means that another 34.3% of additional through put can be handled with the same level of resources. Second, the average productivity of the container ports in the DCs appeared to be higher than those located in the LDCs. The main sources of productive growth in the DCs were based on scale efficiency change (SEC), technical efficiency change (TEC), and potential technological relative change (PTRC), while the main source of productive growth in LDCs was based on SEC. Third, SEC appeared to be the dominant factor that affects the utilization of all ports. Full article

The demographic and economic data together with corresponding maps were used to determine the driving factors for land conversions. This study applied Cellular Automata-Markov Chain (CA-MC) and Multi-Layer Perceptron-Markov Chain (MLP-MC) to model LULC and urban expansions. The performance of the CA-MC and MLP-MC yielded more than 90% overall accuracy to predict the LULC, especially the MLP-MC method. Further, the annual population and economic growth rates were considered to produce the land demand for the LULC in 2014 and 2035 using the statistical extrapolation and system dynamics (SD). It was evident that the simulated map in 2014 resulting from the SD yielded the highest accuracy. Therefore, this study applied the SD method to generate the land demand for simulating LULC in 2035. The outcome showed that urban occupied the land around a half of the BMR. Full article

Water erosion causes reduced farmland productivity, and with a longer period of cultivation, agricultural productivity becomes increasingly vulnerable. The vulnerability of farmland productivity needs assessment due to long-term water erosion. The key to quantitative assessment is to propose a quantitative method with water loss scenarios to calculate productivity losses due to long-term water erosion. This study uses the agricultural policy environmental extender (APEX) model and the global hydrological watershed unit and selects the Huaihe River watershed as a case study to describe the methodology. An erosion-variable control method considering soil and water conservation measure scenarios was used to study the relationship between long-term erosion and productivity losses and to fit with 3D surface (to come up with three elements, which are time, the cumulative amount of water erosion and productivity losses) to measure long-term water erosion. Results showed that: (1) the 3D surfaces fit significantly well; fitting by the 3D surface can more accurately reflect the impact of long-term water erosion on productivity than fitting by the 2D curve (to come up with two elements, which are water erosion and productivity losses); (2) the cumulative loss surface can reflect differences in productivity loss caused by long-term water erosion.

Technology analysis (TA) is an important issue in the management of technology. Most R&D (Research & Development) policies have depended on diverse TA results. Traditional TA results have been obtained through qualitative approaches such as the Delphi expert survey, scenario analysis, or technology road mapping. Although they are representative methods for TA, they are not stable because their results are dependent on the experts’ knowledge and subjective experience. To solve this problem, recently many studies on TA have been focused on quantitative approaches, such as patent analysis. A patent document has diverse information of developed technologies, and thus, patent is one form of objective data for TA. In addition, sustainable technology has been a big issue in the TA fields, because most companies have their technological competitiveness through the sustainable technology. Sustainable technology is a technology keeping the technological superiority of a company. So a country as well as a company should consider sustainable technology for technological competition and continuous economic growth. Also it is important to manage sustainable technology in a given technology domain. In this paper, we propose a new patent analysis approach based on statistical analysis for the management of sustainable technology (MOST). Our proposed methodology for the MOST is to extract a technological structure and relationship for knowing the sustainable technology. To do this, we develop a hierarchical diagram of technology for finding the causal relationships among technological keywords of a given domain. The aim of the paper is to select the sustainable technology and to create the hierarchical technology paths to sustainable technology for the MOST. This contributes to planning R&D strategy for the sustainability of a company. To show how the methodology can be applied to real problem, we perform a case study using retrieved patent documents related to telematics technology. Full article

With industrial integration accelerating in domestic and foreign enterprise, industrial integration is becoming the only way for regional development to break through its bottleneck. Compared with advanced foreign enterprises, there exists a significant gap in regional industrial integration, especially in the urban agglomeration of the energy chemical industries of Urumqi-Changji-Shihezi in Xinjiang. Findings from field visits and quantitative analysis show that the energy chemical industry in urban agglomeration is in a state of dispersed distribution, serious convergence in industrial structure, low level of specialization, and weak collaborative relationships. These issues seriously hamper the sustainable development of urban agglomeration. Specific actions aimed at these problems and the development bottleneck mainly include the integration of industrial parks in the central city and integration orientation on the level of urban agglomeration. Only by speeding up the pace of industry integration can Urumqi-Changji-Shihezi’s urban agglomeration maintain and improve its market competitiveness. Accordingly, it can promote innovation and sustainability in the energy chemical industry and improve the overall level of development. Full article

Due to the frequent urban air pollution episodes worldwide recently, decision-makers and government agencies are struggling for sustainable strategies to optimize urban land use/cover change (LUCC) and improve the air quality. This study, thus, aims to identify the underlying relationships between PM₁₀ concentration variations and LUCC based on the simulated PM₁₀ surfaces in 2006 and 2013 in the Changsha-Zhuzhou-Xiangtan agglomeration (CZT), using a regression modeling approach. LUCC variables and associated landscape indexes are developed and correlated with PM₁₀ concentration variations at grid level. Results reveal that the overall mean PM₁₀ concentrations in the CZT declined from 106.74 μg/m³ to 94.37 μg/m³ between 2006 and 2013. Generally, variations of PM₁₀ concentrations are positively correlated with the increasing built-up area, and negatively correlated with the increase in forests. In newly-developed built-up areas, PM₁₀ concentrations declined with the increment of the landscape shape index and the Shannon diversity index and increased with the growing Aggregation index and Contagion index. In other areas, however, the reverse happens. These results suggest that LUCC caused by urban sprawl might be an important factor for the PM₁₀ concentration variation in the CZT. The influence of the landscape pattern on PM₁₀ concentration may vary in different stages of urban development. Full article

Based on two substitute products, we study the inventory and contract coordination strategy of a three-echelon supply chain, which consists of two suppliers, a manufacturer and a retailer, under supply disruption and stochastic demand. We investigate the channel gross profit model of the centralized supply chain and obtain a unique optimal order quantity. Under a decentralized decision, we find that the commonly-used wholesale price contracts cannot coordinate the system. Then, we propose a buy-back contract and prove that this contract can more efficiently coordinate the system than the former. At last, we show that the integrated performance of the decentralized system can be maximized through choosing the buy-back parameter by the manufacturer and reveal that the effects of supply uncertainty and the substitution behavior of customers on the optimal decision by numerical examples.

The planting of sugarcane crops has expanded in the last decade in the southeast of Brazil, mainly due to its use for biofuel production, such as ethanol. This expansion in the State of São Paulo has occupied land that was previously used for cattle production. The change in land use affects soil and water through changes in ground cover and disturbance associated with farming practices. The objective of the following study was to determine the impact on runoff and erosion resulting from the conversion of pastureland to sugarcane for biofuel production. Erosion plots measuring 100 m² were built on a farm in Itirapina-SP, Brazil, on land with a slope gradient of 9% and soil composed of Quartz-sand Neosols (Typic quartzipsaments). The treatments were an 18-year old pasture and a new sugarcane plantation, with three replicates for each. After each rainfall episode, erosion and runoff were monitored during the first and second years after sugarcane was planted. The results show increased runoff and soil loss during the first year, though levels decreased in the second year when the sugarcane residue mulch ground cover increased. In addition, the necessary rainfall characteristics (e.g., intensity, duration) required to produce runoff and soil erosion were identified. Full article

Environmental degradation threatens the long term resiliency of the US food and farming system. While USDA has provided conservation incentives for the adoption of best management practices (BMPs), only a small percentage of farms have participated in such conservation programs. This study uses conjoint analysis to examine Vermont farmers’ underlying preferences and willingness-to-accept (WTA) incentives for three common BMPs. Based on the results of this survey, we hypothesize that federal cost share programs’ payments are below preferred incentive levels and that less familiar and more complex BMPs require a higher payment. Our implications focus on strategies to test these hypotheses and align incentive payments and other non-monetary options to increase BMP adoption. Full article

This study explores the technical and scale efficiency of two types of Greek fishing vessels, small-scale vessels and bottom trawlers, using a bias-corrected input-oriented Data Envelopment Analysis model. Moreover, the associations between efficiency scores and vessel’s and skipper’s characteristics are also explored. The results indicate that small-scale vessels achieve a very low average technical efficiency score (0.42) but a much higher scale efficiency score (0.81). Conversely, bottom trawlers achieve lower scale but higher technical efficiency scores (0.68 and 0.73, respectively). One important finding of this study is that the technical efficiency of small-scale vessels, in contrast to trawlers, is positively associated with the experience of the skipper. In a looser context, it can be said that small-scale fisheries mainly rely on skill, whereas bottom trawlers rely more on technology. This study concludes that there is space for improvement in efficiency, mainly for small-scale vessels, which could allow the achievement of the same level of output by using reduced inputs.

An urban forest assessment is essential for developing a baseline from which to measure changes and trends. The most precise way to assess urban forests is to measure and record every tree on a site, but although this may work well for relatively small populations (e.g., street trees, small parks), it is prohibitively expensive for large tree populations. Thus, random sampling offers a cost-effective way to assess urban forest structure and the associated ecosystem services for large-scale assessments. The methodology applied to assess ecosystem services in this study can also be used to assess the ecosystem services provided by vacant land in other urban contexts and improve urban forest policies, planning, and the management of vacant land. The study’s findings support the inclusion of trees on vacant land and contribute to a new vision of vacant land as a valuable ecological resource by demonstrating how green infrastructure can be used to enhance ecosystem health and promote a better quality of life for city residents.

Understanding human mobility patterns provides us with knowledge about human mobility in an urban context, which plays a critical role in urban planning, traffic management and the spread of disease. Recently, the availability of large-scale human-sensing datasets enables us to analyze human mobility patterns and the relationships between humans and their living environments on an unprecedented spatial and temporal scale to improve decision-making regarding the quality of life of citizens. This study aims to characterize the urban spatial-temporal dynamic from the perspective of human mobility hotspots by using mobile phone location data. We propose a workflow to identify human convergent and dispersive hotspots that represent the status of human mobility in local areas and group these hotspots into different classes according to clustering their temporal signatures. To illustrate our proposed approach, a case study of Shenzhen, China, has been conducted. Six typical spatial-temporal patterns in the city are identified and discussed by combining the spatial distribution of these identified patterns with urban functional areas. The findings enable us to understand the human dynamics in a different area of the city, which can serve as a reference for urban planning and traffic management. Full article

This paper examines how and to what degree government policies of garbage fees and voluntary source separation programs, with free indoor containers and garbage bags, can affect the effectiveness of municipal solid waste (MSW) management, in the sense of achieving a desirable reduction of per capita MSW generation. Based on city-level panel data for years 1998–2012 in China, our empirical analysis indicates that per capita MSW generated is increasing with per capita disposable income, average household size, education levels of households, and the lagged per capita MSW. While both garbage fees and source separation programs have separately led to reductions in per capita waste generation, the interaction of the two policies has resulted in an increase in per capita waste generation due to the following crowding-out effects: Firstly, the positive effect of income dominates the negative effect of the garbage fee. Secondly, there are crowding-out effects of mandatory charging system and the subsidized voluntary source separation on per capita MSW generation. Thirdly, small subsidies and tax punishments have reduced the intrinsic motivation for voluntary source separation of MSW. Thus, compatible fee charging system, higher levels of subsidies, and well-designed public information and education campaigns are required to promote household waste source separation and reduction.
