Does Pure Contemplation Belong to Architecture? The Denied Ramps at the Church of San Salvatore in the Santa Giulia Museum in Brescia

This paper addresses the issue of balancing the two values underlying the accessibility and conservation of cultural heritage: its use and its protection. These values are often, wrongly, regarded as opposites, or as incompatible. The reason for this contrast originates in the way of understanding ancient architecture and in the value of the relationship between architecture and people. This issue is considered by presenting a recent case concerning the Museum of Santa Giulia in Brescia, a multi-layered complex that preserves evidence ranging from the prehistoric to the contemporary age, housed in a monastic complex of Longobard origin. The recent failure to build some ramps proposed for increasing accessibility to the church of San Salvatore, an integral part of the museum's itinerary, offers an opportunity to reflect on the need for better integration between different, and only apparently opposed, instances. The topic is dealt with by referring to the most recent disciplinary reflections in the field of conservation carried out in Italy with respect to the issue of accessibility to the cultural heritage, without neglecting juridical-normative aspects and international documents, such as the Faro Convention. This multidisciplinary reading aims to highlight the main significance of accessing cultural heritage, with reference also to the objectives of sustainable development and the human development of the individual and the reference community.

Higher Education and Universal Design in Tanzania. A New Model of Inclusion and Sustainable Development

The need to create a more inclusive society in Tanzania is confronted with a discrepancy between the aims of a regulatory framework, aimed at making Higher Education spaces inclusive, and the question of the right of access to built environments, particularly in universities. The study presents the pilot case of the RUCU's Learning Center for Disabilities to demonstrate that the combination of UDL, architectural accessibility and international cooperation can give impetus to new research and application themes, creating innovative models and good practices to be disseminated for a new shared awareness.

Rethinking Play Environments for Social Inclusion in Our Communities

"Make cities and human settlements inclusive, safe, resilient and sustainable" is one of the 17 Sustainable Development Goals of the 2030 Agenda approved by the UN General Assembly. This means that every Country must commit to facing the challenge of increasingly welcoming and barrier-free cities, providing "universal access to safe, inclusive and accessible, green and public spaces, in particular for women and children, older persons and persons with disabilities". The mission of inclusive play is to create accessible and sensory-rich play environments that meet the widest range of users and abilities offering several and stimulating play opportunities in the same setting. In many playgrounds of our cities, for persons with disabilities, accessing, moving and making play experiences is not easy, in some cases it is not possible. The paper presents the results of a study carried out in order to investigate the inclusiveness of outdoor playgrounds and introduces the need of new perspectives towards a new and innovative view of inclusive playgrounds. The development process of the checklist for assessing the inclusiveness of outdoor playgrounds involved four steps. Step 1: Definition of the main concepts of investigation and generation of the items on the basis of the relevant literature and best practices. Step 2: Scaling and scoring. Step 3: Pilot test to verify the real applicability of the checklist. Step 4: Design of the final checklist. The final checklist was applied to a sample of playgrounds belonging to an Italian urban area selected as a case study in order to make a picture of the state of the art of the playgrounds built in recent years. After the checklist application, the processing of the collected data shows that there is still much to be done to make urban play areas fully accessible and usable by all. Physical accessibility (not always guaranteed) to the play area and to the play components is not enough. Currently there are few playgrounds that ensure inclusive experiences by offering a wide range of equipment with different game values and levels of challenge and services that can be used by everyone. Inclusive playgrounds in our communities are still a small percentage compared to all existing play environments, although there is a greater attention to the theme from year to year. The importance of inclusive playgrounds is recognized by everyone at a theoretical level, but in practice it is still necessary to promote, implement and verify the culture of accessibility and inclusive play. If we want inclusive cities, it is necessary to find skills and resources as well as effective operational tools to map the critical issues of existing playgrounds and to implement restyling interventions or new projects of successful and comprehensive inclusive play environments.

Assessment of Ecological Environment Quality for Urban Sustainable Development Based on AHP

Cities are gradually developed on the basis of adapting and transforming the natural environment. In a certain urban area, human activities, natural environment, and other factors and their mutual influence constitute the urban ecological environment. Therefore, the evaluation of urban ecological environment quality is of great significance to the analysis of urban development. This paper takes a city in Western China as the evaluation object, uses AHP to determine the index weight, reasonably analyzes the current situation of the urban ecological environment, and further comprehensively evaluates the quality of the urban ecological environment. The study shows that from 2013 to 2018, the comprehensive capacity of the city's ecological environment quality showed a steady upward trend, except that the natural disasters of floods and mudslides in 2014 had a certain degree of fluctuation. The comprehensive index of ecological environment quality has increased from 0.337 in 2013 to 0.412 in 2018. The overall level is still low, but the development speed is relatively stable. The urban ecological environment has been gradually improved, and society, economy, and nature have maintained a certain degree of sustainable development.

Sustainability in the Sardinian sheep sector: A systems perspective, from good practices to policy

Three million sheep raised on 10 000 active farms operating in traditional and innovative farming systems in Sardinia, Italy, account for 13% of sheep milk production in the European Union (EU). Almost all of the milk delivered is processed to sheep cheese and is destined for world trade. The Sardinian dairy sheep sector also emits approximately 1600 kt CO₂ eq/year, approximately 60% of regional livestock greenhouse gas (GHG), prompting the need for regional mitigation plans. The SheepToShip LIFE project (EU-LIFE Climate Change Action 2014-2020) is a regional case study to test emission mitigation strategies. Based on the SheepToShip LIFE findings, this paper presents a systems perspective against the backdrop of the Sustainable Development Goals (SDGs) framework, with the aim of underlining system interlinkages between environmental, societal, and economic objectives. The project included (i) a life cycle thinking approach featuring environmental and socioeconomic traits of 18 sheep farms, (ii) on-farm implementation and demonstration of eco-innovative mitigation techniques indicating the most viable actions to reduce impact, (iii) focus groups discussing beliefs and reactions of the main stakeholders, and (iv) group model building producing a causal loop diagram from a systems thinking approach and exploring insights for regional policy-making that aligns with the SDGs. Causal links connect public interventions and stakeholder interaction (SDG 17) to boost farm eco-innovations (SDGs 9 and 8) and education and farmer training (SDG 4), and they foster efficient production (SDG 12) and high-quality food provisioning (SDG 2). These benefits contribute to climate change mitigation (SDG 13), water quality (SDG 6), and farm ecosystem services (SDG 15). Integr Environ Assess Manag 2022;18:1187-1198. © 2022 SETAC.

Marine macroalgae as a feasible and complete resource to address and promote Sustainable Development Goals (SDGs)

Because the world's population is increasing, science-based policies are needed to promote sustainable global development. It is important to maintain and restore the environment and help human society overcome the risks from industrialization and unsustainable exponential growth. In recent years, many studies have highlighted that macroalgae represent a key marine resource for ecological and sustainable living, thus helping to address today's global problems, such as water pollution, ocean acidification, and global warming. Macroalgae show the potential to provide innovative, ecofriendly, and nutritious food sources and natural compounds for various industries, such as biomedical, food, agricultural, and pharmaceutical industries. This review discusses how macroalgae can help us today and how they can promote a more sustainable way of life in the future. It also discusses the potential danger for ecosystems and the global population if these organisms are not part of the solution but part of the problem.

Towards smart and sustainable development of modern berry cultivars in Europe

Fresh berries are a popular and important component of the human diet. The demand for high-quality berries and sustainable production methods is increasing globally, challenging breeders to develop modern berry cultivars that fulfill all desired characteristics. Since 1994, research projects have characterized genetic resources, developed modern tools for high-throughput screening, and published data in publicly available repositories. However, the key findings of different disciplines are rarely linked together, and only a limited range of traits and genotypes has been investigated. The Horizon2020 project BreedingValue will address these challenges by studying a broader panel of strawberry, raspberry and blueberry genotypes in detail, in order to recover the lost genetic diversity that has limited the aroma and flavor intensity of recent cultivars. We will combine metabolic analysis with sensory panel tests and surveys to identify the key components of taste, flavor and aroma in berries across Europe, leading to a high-resolution map of quality requirements for future berry cultivars. Traits linked to berry yields and the effect of environmental stress will be investigated using modern image analysis methods and modeling. We will also use genetic analysis to determine the genetic basis of complex traits for the development and optimization of modern breeding technologies, such as molecular marker arrays, genomic selection and genome-wide association studies. Finally, the results, raw data and metadata will be made publicly available on the open platform Germinate in order to meet FAIR data principles and provide the basis for sustainable research in the future.

Biocapacity convergence clubs in Latin America: an analysis of their determining factors using quantile regressions

Latin America experiences an increasing urban primacy index and a rapid expansion of the financial system, putting direct pressure on the demand for resources to satisfy the consumption of large cities. We investigate the convergence of per capita biocapacity in 16 Latin America countries and evaluate the factors that influence its evolution over time. Specifically, we analyze the impact of the urban primacy index, economic progress, and the financial globalization index on the convergence of per capita biocapacity. We use the methodological framework developed by Phillips and Sul Econometrica 75:1771-1855, (2007) to analyze the convergence and the formation of convergence clubs of biocapacity during 1970-2017. The findings indicate that the countries of the region do not share a common trend of biocapacity, although they are grouped into five converging clubs. Biocapacity transition analysis reveals that countries have heterogeneous transition pathways between them. Using marginal effects, we find that the urban primacy index and economic progress reduce the biocapacity. The effect of the financial globalization index on biocapacity is not conclusive. The quantile regressions reveal that quantiles' impact of the urban primacy index and financial globalization on per capita biocapacity is heterogeneous. However, the effect of economic progress on biocapacity that predominates among quantiles is positive. The adoption of common policies among the countries that form the converging clubs could improve the effectiveness of pro-environmental policies and promote the achievement of the Sustainable Development Goals related to environmental quality.

Effects of the green supply chain management practices on firm performance and sustainable development

The idea of sustainable development and green supply chain management is considered at the underlying stage in the research and academic fields, particularly in the rising economies of Asia. This research investigates the persuasive force of the firm's green supply chain management practices with the mediating part of the competitiveness and investment recovery. Data was collected from the 12 ISO 9001 and ISO 14001 leather industries based in Pakistan. We distributed the 350 questionnaires at 12 leather industries, and the questionnaire was also transferred on Google Forms, and 50 questionnaire mail to different individuals who work in leather industries of other cities of Pakistan; out of 350 questionnaires, 183 were filled, and the remaining questionnaires were incomplete, and out of 50 emails, we get the response of 33 emails, and evaluated the model of this study by using the partial least square structural equation modeling PLS-SEM. We interact with the employees of leather industries and try to understand how they are following the green practices in their firms. This research uses resource dependence theory as the theoretical base. This study elaborates how the organization's behavior is affected by the external resources of the corporation. The actual outcomes uncover that green supply chain management activities positively impacting the firm's performance, where competitiveness and investment recovery play a mediating role among intra-organizational green practices.

Progress towards the 2030 sustainable development goals: direct and indirect impacts on neurological disorders

The United Nations' Sustainable Development Goals (SDGs) were set forth in 2015 as a blueprint for all nations to create a more sustainable future together. These 17 social, environmental, and economic goals have established targets to meet globally by the year 2030, with a focus on pro-poor initiatives, gender equality, and ending hunger. The relationship of the SDGs with neurological disorders and how the achievement of the SDGs intersects with the future of neurological practice have not been comprehensively examined. However, the incidence of neurological disorders, the outcomes of people living with neurological disorders, and the training of future neurologists can be interlinked, directly or indirectly, with programming for the SDGs and their eventual achievement. Each SDG is reviewed in the context of neurology. This lens can inform programming and policy, enhance research and training, and improve inter-sectoral action for neurological disorders worldwide.

Data-driven evaluation and optimization of the sustainable development of the logistics industry: case study of the Yangtze River Delta in China

In this study, a data-driven way is proposed to evaluate and optimize the sustainable development of the logistics industry (LI). Based on a comprehensive consideration of economic, societal, and environmental factors, an evaluation index system was established for the sustainable development of the logistics industry (LISD). Logistics industry-related data were collected from the Yangtze River Delta (YRD) from 2011 to 2020. The anti-entropy method was used to determine the index weight and process the data. Furthermore, the coupling harmonization degree and barrier degree models were used to analyze the coordinated development of each subsystem and identify key obstacles. Our results indicate that there are significant temporal and spatial differences in the level of LISD in YRD, with Shanghai (score 0.4834) being the best and Anhui (score 0.4553) the worst, showing a wave-like evolution in time. The coupling and coordination states among the subsystems are significantly different, with that of environmental benefits and other subsystems being poor. Moreover, innovation ability and environmental benefits are the main obstacle factors of this system. Based on the results of this study, targeted optimization countermeasures are put forward and evaluation indicators and research methods are suggested, which will provide the government and practitioners decision support, as well as provide theoretical and methodological support for LISD.

The sustainable agriculture imperative: A perspective on the need for an agrosystem approach to meet the United Nations Sustainable Development Goals by 2030

The development of modern, industrial agriculture and its high input-high output carbon energy model is rendering agricultural landscapes less resilient. The expected continued increase in the frequency and intensity of extreme weather events, in conjunction with declining soil health and biodiversity losses, could make food more expensive to produce. The United Nations has called for global action by establishing 17 sustainable development goals (SDGs), four of which are linked to food production and security: declining biodiversity (SDG 15), loss of ecosystem services and agroecosystem stability caused by increasing stress from food production intensification and climate change (SDG 13), declining soil health caused by agricultural practices (SDGs 2 and 6), and dependence on synthetic fertilizers and pesticides to maintain high productivity (SDG 2). To achieve these SDGs, the agriculture sector must take a leading role in reversing the many negative environmental trends apparent in today's agricultural landscapes to ensure that they will adapt and be resilient to climate change in 2030 and beyond. This will demand fundamental changes in how we practice agriculture from an environmental standpoint. Here, we present a perspective focused on the implementation of an agrosystem approach, which we define to promote regenerative agriculture, an integrative approach that provides greater resilience to a changing climate, reverses biodiversity loss, and improves soil health; honors Indigenous ways of knowing and a holistic approach to living off and learning from the land; and supports the establishment of emerging circular economies and community well-being.

Impact of market constraints on the development of small-scale biogas technology in Sub-Saharan Africa: a systematic review

The sustainable production and use of small-scale biogas energy are required to ensure clean household energy access in developing countries, including the Sub-Saharan Africa (SSA) region. This is influenced by market risks, which can be identified as political, economic, social, technical, legal, and environmental (PESTLE). This study examines peer-reviewed and grey literature for the period from 2000 to 2020 to identify the PESTLE constraints and assess their impact on the sustainable development of the technology in the SSA region. The production of biogas with small-scale plants is commonly done by rural and peri-urban households. Results show that economic constraints are the most dominant and reducing at a slow pace. This is followed by political constraints, which have received much attention in the last two decades. Despite the policy improvements, broader national bioenergy policies and interventions are still to make significant gains, especially in the Central African region. In order of significance, the Southern, East, and West Africa regions have made greater progress in reducing the constraints. To achieve the sustainable development of the technology, there is a need to further address the PESTLE constraints at national and regional levels. This study partly deduces that the unsustainable production, use, and inadequate regulation of the small-scale biogas sector are delaying its transition in the SSA region.

Validation of the environmental Kuznets curve hypothesis and role of carbon emission policies in the case of Russian Federation

Climate change currently observed and expected in the future is associated with risks to security and sustainable development and natural and irreversible consequences. To minimize these risks, it is necessary to adapt the public administration, economic sectors, and regional infrastructure to the changing climate conditions. This paper discovers the links between CO₂ emissions and their key determinants such as economic growth, energy consumption, population, trade openness, and financial development including the period from 1990 to 2020 to test the environmental Kuznets curve (EKC) hypothesis by using ARDL bound test for the Russian Federation. Findings reveal that energy consumption and population have a positive impact on CO₂ emissions, while economic growth, financial development, and trade openness have been found to decrease CO₂ emissions in the long term. The results of this paper show that there is a "U"-shaped relationship between CO₂ emissions and economic growth in the Russian Federation. This shows that EKC is valid up to a certain income level in the Russian Federation, and when this income level is exceeded, a positive relationship will begin between economic growth and environmental degradation. As a policy implementation, policymakers must implement clean energy technology policies to achieve the 2060 net zero carbon target. Policies such as fossil-based energy use and reducing energy intensity should be adopted.

[Urbanization and ecological effect in mid-southern Liaoning urban agglomeration, China]

China has entered the stage of rapid urbanization since the 1990s, resulting in a series of environmental problems. Based on the nighttime light remote sensing data and land use data from 1995 to 2020, we extracted the compound night light index (CNLI) to measure the urbanization level of mid-southern Liaoning urban agglomeration, evaluated habitat quality by InVEST model. We examined the relationship between urbanization level and habitat quality in mid-southern Liaoning urban agglomeration by using the correlation analysis method and the geographic weighted regression model. The results showed that CNLI increased by 0.14 from 1995 to 2020. The urbanization level increased continuously, with a pattern of "low in the east and high in the west". The habitat quality decreased by 0.005, showing a pattern of "high in the east and low in the west". The ecological environment became worse. There was a significant negative spatial correlation between urbanization level and habitat quality in mid-southern Liaoning urban agglomeration. The negative impact of urbanization level on habitat quality gradually decreased. In order to alleviate habitat degradation caused by urbanization and realize the coordinated and sustainable development of regional social economy, it was urgent to take a series of measures, such as delimiting the ecological protection red line, improving the intensive use of land, delimiting the urban boundary, promoting the coordinated development of regional integration.

Study on sustainable development and construction of karst mountain city based on the concept of a sponge city

In recent years, there has been rapid urbanization development in China. The rapid expansion of cities and the increase in the proportion of the area of impervious surfaces have caused urban flooding problems. The karst area in Southwest China is characterized by a sensitive ecosystem, poor self recovery ability and typical karst development. The problems of a fragile and imbalanced water ecology are particularly prominent in karst areas, making it necessary to explore the applicability of the concept of sponge cities in such environments. This study reviews the technical ideas, methods and concepts of sponge cities in China and abroad in recent years. Guiyang, a typical karst mountain city in China, was taken as an example in this study. This was because Guiyang has special hydrogeological characteristics as well as the current urbanization development processes that are affecting the water resources and the environment in the region. It is believed that the construction of mountain sponge cities in karst areas should be mainly through source reduction, process control and end management, combined with intelligent construction methods. Focus should be on strengthening the prevention and control of soil erosion in key areas and risk areas and on properly handling the relationship between urban construction and water resources and ecological environment protection.

Study on cooperative constraint zoning of water environment

This study comprehensively considers two elements of water environmental sensitivity and pressure using the combination of qualitative analysis and quantitative calculation. And it puts forward the water environmental collaborative constraint zoning method and focuses on the construction of the water environmental collaborative constraint zoning evaluation index system using the fuzzy optimization programming model to determine the index weight. This study takes the Liaohe River Basin in Liaoning Province as a study area through two-dimensional quadrant analysis of water environmental sensitivity and pressure; it is divided into four types of areas: high-pressure and high-sensitivity area (HP-HS area), high-pressure and low-sensitivity area (HP-LS area), low-pressure and high-sensitivity area (LP-HS area) and low-pressure and low-sensitivity area (LP-LS area), respectively. The results show that the proportion of HP-HS area is 28.4%, the proportion of HP-LS area is 10.1%, the proportion of LP-HS area is 22.2% and the proportion of LP-LS area is 39.3%, respectively. The evaluation results are in line with the actual situation of the Liaohe River Basin in Liaoning Province. According to the results of different zoning, this research puts forward the optimization and adjustment scheme of industrial layout to achieve the comprehensive and coordinated sustainable development of population, economy, society, and environment in the study area. The research results also have been applied to the formulation of '14th Five-Year Plan' for water ecological environment protection of key river basins in Liaoning Province.

Mapping the scientific structure and evolution of renewable energy for sustainable development

The integration of renewable energy and sustainable development (RE&SD) can help overcome existing obstacles and create opportunities for renewable energy deployment to achieve sustainable development goals. In view of the limited research on science mapping and visualization analyses of RE&SD, this study sought to determine the scientific structure and evolution based on longitudinal and mapping change analysis. As an entity in the knowledge base, keyword and subject were considered essential information of documents. The co-word network was generated using SciMAT to reveal the dynamic aspects of the scientific research in the five subperiods. The thematic evolutionary analysis identified two main RE&SD thematic areas, with the current research hotspots that involved technological, environmental, sustainable energy innovation, and sustainable biofuel contributions. The alluvial diagram using MapEquation revealed significant structural changes from subject data. Clusters of subjects continued to grow, and more interdisciplinary integration was undergoing. This study provides a systematic study of RE&SD research, and the future research of RE&SD may inevitably consider renewable energy investment and renewable energy perspective approaches to achieve sustainable development goals.

Polycentric and resilient perspectives for governing the commons: Strategic and law and economics insights for sustainable development

Commons governance theory is central to identifying and managing conflicts arising from natural and cultural resources traps. Scholars - using game theory and economic analysis of law - have proposed alternative models, consisting of a set of mitigated scenarios, multiple players, and new equilibria in commons governance. Likewise, novel legal innovations of the commons have also been designed. Reinterpreting the commons in light of political economy, ecology, and pluralistic approaches, a critical review of existing scholarship, economic analysis of law, and case study investigations are performed. Examining an array of views - including governance of water in Ecuador, Bolivia, and Italy - a research and policy agenda is put forward to offer original interpretations and novel holistic perspectives. Germane environmental policy implications deriving from SDGs, resilient governance, and polycentric perspectives are thus extrapolated. Finally, pluralistic frameworks drafted by mitigation and adaptation are measured by improved sustainable development performance in commons, resource, and water governance.

Life Cycle Assessment support to environmental ambitions of EU policies and the Sustainable Development Goals

The European Green Deal and the Sustainable Development Goals (SDGs) ask for a more holistic approach to production and consumption along value chains. The role of Life Cycle Assessment (LCA) in supporting policy design and monitoring is then pivotal to achieving policy ambitions. This paper explores the potential support of LCA to EU (European Union) policies and the SDGs, considering also the Planetary Boundaries (PBs) framework. The assessment focuses on (a) the relationship between LCA, the SDGs, and the European Green Deal; (b) the potential use of LCA in support of the monitoring of SDG12 and the environmental impacts of production and consumption; and (c) the relevance of an absolute sustainability dimension, including the integration of the PBs framework in EU policy and the SDGs. Results highlight that the interlinkages between LCA, EU policy, SDGs, and the PBs can be classified as existing, missing, or existing depending on the LCA framework. In general, LCA was identified to strengthen and further enable EU policies toward achieving the SDGs while remaining within the physical limits of the planet. This is because LCA can be a pivotal method to quantify and assess environmental impacts of value chains and consumption patterns, enabling the evaluation of their implication on environment-related SDGs and assessing them against the PBs. The example of the Consumption Footprint highlights that the concept and Life Cycle Impact Assessment method of an LCA framework can determine the linkage among EU policy, SDGs, and the PBs. Integr Environ Assess Manag 2022;18:1221-1232. © 2022 The Authors.

Circular economy strategy and waste management: a bibliometric analysis in its contribution to sustainable development, toward a post-COVID-19 era

A descriptive analysis of 416 documents was performed using bibliometric techniques, in order to gather existing knowledge in circular economy focusing on waste management (2007-2020). The results of this study indicate that annual scientific production increased 94% in the last 5 years, highlighting the countries of Italy, Spain, the UK, China, Brazil, and India. Between the most cited documents stand out those related to calorific value of municipal solid waste and waste to energy technologies for achieving circular economy systems. The conceptual analysis indicates strong linkage between circular economy and sustainable production, waste management, and recycling. Emerging research trends evolved from processes and industry-oriented approach (2017) toward waste management, recycling, and circular economy (2019) and sustainable development and urban solid waste (2020). The analysis reveals five dominant circular economy and waste research themes: (1) greenhouse gases; (2) circular economy, waste management, and recycling; (3) life cycle; (4) waste treatment; and (5) anaerobic digestion and recovery; trends research are related to policy interventions, and enforcement of authorities' regulations to foster circular economy transition, increase the use of practices of recycling and reusing, as well as discourage a growing consumption culture. Results found denote the challenge represented by the implementation of comprehensive policies in circular economy. The above being a key alternative for green recovery in response to the current COVID-19 pandemic.

The impact of land price distortion on green development efficiency: mechanism discussion and empirical test

Based on the panel data of 30 Chinese provinces, the Cobb-Douglas production function and GML index were constructed to measure the degree of land price distortion and green development efficiency, respectively, in China, and the System Generalised Method of Moments model was employed to explore the relationship between land price distortion and green development efficiency, and a mediating effect model was further constructed to analyse the transmission mechanism. The results show that, first, land price in China is characterised by a negative distortion, but the degree of negative distortion tends to decrease after 2010. Second, land price distortion significantly inhibits the improvement of green development efficiency; this conclusion still holds after a series of robustness tests, and land price distortion significantly promotes the progress of green technology, while significantly inhibiting the improvement of green technology efficiency. Third, the results of the mediating effect show that the inhibiting effect of land price distortion on green development efficiency is mainly achieved through three channels: house price, industrial structure and infrastructure. Finally, policy recommendations for green sustainable development are put forward from the aspects of land supply structure adjustment and so on.

Research on the spatiotemporal evolution and influencing factors of green economic efficiency in the Yangtze River Economic Belt

In the Yangtze River Economic Belt (YREB), the green economy is an essential to sustainable economic development. In this study, we calculated a comprehensive index of environmental pollution based on the global entropy weight method and used the super slacks-based measure (SBM) model to estimate the green economic efficiency (GEE) of provinces and cities in the YREB from 2005 to 2018. Subsequently, we explored temporal and spatial evolution characteristics combined with the Theil and Moran indexes, and adopted the spatial Dubin model to analyze its influencing factors. We divided the YREB into three watersheds to facilitate the analysis. The results show that the GEE in the YREB initially decreased and then increased, and the difference among the three major watersheds was higher than that within the watershed. We found a positive spatial autocorrelation in the development level of the green economy in the YREB. While industrial structure had a negative effect, economic development, scientific and technological level, and environmental regulation all had a positive effect on GEE. Finally, we offered policy recommendations to improve the level of green development in the YREB.

Capital misallocation, technological innovation, and green development efficiency: empirical analysis based on China provincial panel data

The study aims to analyze the impacts of capital misallocation and technological innovation on green development efficiency in China by using the panel data from 2000 to 2018. We employ the Super-SBM model to evaluate green development efficiency and use the system generalized method of moments (GMM) for empirical estimation. The results suggest that capital misallocation has a significant inhibitory effect on green development efficiency. Moreover, capital misallocation restrains technological innovation, which plays an important role in improving green development efficiency. Further research on the effect of regional heterogeneity indicates that the negative impact of capital misallocation on green development efficiency is more significant in the central and western regions, while the effect is not significant in the eastern region. Our findings provide useful policy implications for improving green development efficiency in China.

The Global Contributions of Working Equids to Sustainable Agriculture and Livelihoods in Agenda 2030

Small farmers produce most food in low- and middle-income countries and most small farmers rely on directly or indirectly working equids (WE). The lack of methods and metrics for assessing the role of WE hampers realisation of WE contributions. Based on literature review and a survey of WE welfare experts, we propose a framework for optimising WE potential based on two axes of sustainable development goals (SDGs) and value chains. WE contribute especially to earning and sparing income (largely in food production) (SDG 1), but also have roles in accessing health and hygiene services and products (SDG 3 and 5), providing edible products (SDG 2), and benefiting women (SDG 6), with lesser contributions to other SDGs, notably climate action (SDG 13). Experts identified barriers to appropriate appreciation of WE contributions, in order to target actions to overcome them. They found WE are neglected because they belong to farmers who are themselves neglected; because information on WE is inadequate; and, because the unique nature and roles of WE means systems, policies, investors, markets and service providers struggle to cater for them. Harnessing WE to optimally contribute to sustainable development will require generating better evidence on their contributions to SDGs, ensuring better integration into ongoing efforts to attain SDGs, and building the WE capacity among development actors.
