Sustainable Fishery Value Chain (SFVC): Study Case in Tilapia Industry

This research is built on the concept of sustainable value chains, where a framework for sustainable value chain analysis emerges that covers not only economic aspects but also includes environmental and social impacts in a collaborative model of value chain management. It explores the dimensions on which value chain sustainability should focus. It illustrates how and why it is necessary to take a broader perspective in ensuring the internal economic sustainability of the chain in line with its external socio-environmental consequences. This research aims to analyze the sustainability of the tilapia processing value chain. This research uses the Multi-Dimensional Scaling analysis method supported by Rap-fish software. The Rapfish methodology is a flexible technique that rapidly assesses fisheries status by integrating ecological and human factors according to identified norms. The results of this research show that the sustainability of the tilapia processing value chain is considered entirely sustainable from economic, social, and environmental aspects, with a sufficient sustainability index of 74.40%. The sustainability of the value chain relies on four key actors: tilapia cultivators, collectors, processors, and distributors. The sustainable tilapia processing value chain strategy in North Sumatra can limit floating net cages by considering the environmental carrying capacity and supported by suitable policies and active stakeholder participation in community-based legal institutions. This research found this is a strong sustainability concept if implemented with better governance and policy management in the tilapia industry value chain.

Monitoring environmental sustainability in Japan: an ESGAP assessment

AbstractThis paper assesses the environmental sustainability of Japan by applying the environmental sustainability gap (ESGAP) framework, which builds on the concepts of strong sustainability, critical natural capital, environmental functions, and science-based reference values. The assessment is carried out using two indices of environmental sustainability (Strong Environmental Sustainability Index (SESI) and Strong Environmental Sustainability Progress Index (SESPI)) that provide a snapshot and a trend perspective on environmental sustainability performance and on progress toward it. The results reveal that Japan has not experienced significant changes in terms of aggregate environmental sustainability throughout the 2011–2017 period, but this is primarily a consequence of the mutually offsetting movements of different indicators. The country performs best for the human health and other welfare indicators, but worst for the sink function indicators such as the per-capita CO2 emissions and the eutrophication of fresh water. The indices also expose the main policy areas that Japan needs to strengthen to improve its environmental performance. They include issues such as tropospheric ozone pollution, which has long been discussed in scientific literature but never been a primal policy focus of the government until very recently.

Strongly Sustainable Development Trajectories: The Road to Social, Environmental, and Macroeconomic Stability – Introduction

This brief introduction discusses the concept of strong sustainability from three basic pillars: The non-substitutability of natural capital, the necessity to have holistic analysis of sustainability using multi-dimensional criteria, and the construction of a new social contract to formulate sustainable trajectories.

Is Hazelnut Farming Sustainable? An Analysis in the Specialized Production Area of Viterbo

Specialized agricultural systems may have a strong environmental impact, thus affecting the sustainability of production. The aim of this study is to evaluate the overall environmental impact of the hazelnut production, focusing on the main Italian production area, which is located in the province of Viterbo (central Italy). The theoretical approach adopted in this study refers to the paradigm of ecological economics, recalling the concept of strong sustainability through the conservation of natural capital and its non-replacement with economic capital. This environmental sustainability of farming systems is assessed through the ecological balance (EB) tool by comparing the availability and use of natural capital in each farm scenario. This allows to understand the extent of the load generated on the environment by the different farm’s typologies, as well as the impact on the entire territory where hazelnut cultivation is predominant. For the assessment, local typical farm scenarios are assessed through a Delphi consultation of a panel of experts, thus characterizing the cultivation techniques most frequently adopted in the area. Three typologies of representative farms emerge, which mainly differ for cultivation method and dimension. Cultivation methods associated with the larger farms (both conventional and organic) generate a positive contribution to EB, whereas small farms (conventional) have a negative EB due to the high utilization of inputs. However, the positive balance of the large farms compensates for the negative balance of the small ones. This determines a total positive environmental balance of the specialized production area of Viterbo, equal to 9412 gha. This means that hazelnut farming at a territorial level is sustainable thanks to specific farm managements, which can be promoted by policy-makers.

Ecological Balance of Agri-Food Supply Chains—The Case of the Industrial Tomato

Tomatoes are one of the major productions in Italy. One of the main cultivation areas is the southern plain of Capitanata (Puglia, Southern Italy). However, a series of impacts from cultivation to distribution are connected to this production. Different methodologies have been proposed to evaluate and quantify these impacts from the single product to the supply chain. This work proposes a methodology for assessing environmental sustainability, using the agri-food chain of industrial tomatoes in a specific area of Italy (Puglia) as a case study. The theoretical approach adopted refers to the paradigm of ecological economics, recalling the concept of strong sustainability through the conservation of natural capital and its non-replacement with economic capital. This condition can be assessed through the ecological balance tool by comparing the availability and use of natural capital in economic activities. The aim of this study was to understand the extent of the load generated on the environment, thus evaluating whether the carrying capacity of the agricultural system was able to support the environmental load of the entire supply chain. The results show an overall unsustainability of the entire supply chain with a value of EB = −1911.49 gha. The agricultural phase is the only one to present a positive value EB = +62.99 gha, which fails to compensate for the impacts of the transport (EB = −349.13) and industrial (EB = −1630.96) phases. To our knowledge, this is the first study to assess the sustainability of the tomato food chain using the ecological footprint method. In the agricultural sector, there is a constant search for tools capable of combining economic efficiency and environmental sustainability. In this sense, the ecological footprint methodology provides essential information that can be used by policymakers of different levels to define sustainable development strategies.

A teaching strategy based on active learning which promotes strong sustainability that empowers students to have a different type of relationship with the environment

Some human activities have caused a serious environmental crisis, producing irreversible damage and loss of resources and diversity, which is why a strong sustainability approach is required to keep human activities within planetary boundaries. However, a strong sustainability concept can be difficult for teachers to convey and for students to grasp, because it has few practical examples and applying it seems utopian. This article presents a teaching strategy of active learning for teaching strong sustainability at the university level and evaluates its usefulness for empowering students for another type of relationship with the environment. The teaching strategy is supported by a pedagogy that promotes critical thinking and recognizes learning as a way of questioning and empowering oneself. The teaching strategy was successfully applied in three university subjects that promote environmental education. Based on an online questionnaire to enrolled students (N = 87; 46F, 41M), the perspective of the teacher and the critical-thinking of authors, it was demonstrated that the teaching strategy allowed the strong sustainability concept to be appropriated by students of different disciplines, and demonstrated the feasibility of its practical application. Finally, the teaching strategy can be useful for teaching several disciplines, for curricular integration, and for promoting societal changes to achieve sustainability.

Spatio-Temporal Evolution and Influencing Factors of Ecological Well-Being Performance from the Perspective of Strong Sustainability: A Case Study of the Three Gorges Reservoir Area, China.

The concept of strong sustainability suggests that natural capital is irreplaceable and emphasizes that human natural consumption cannot exceed the carrying capacity of the ecological environment. In the realistic context of tightening resource constraints and ecological degradation, how to explore the optimal economic and well-being output under certain ecological constraints has become an important topic in sustainability research. Ecological well-being performance (EWP) can comprehensively reflect the efficiency of natural resources and ecological inputs into the well-being level and has become an important tool for sustainable development research. Based on strong sustainability, this paper constructs an EWP evaluation index system. It decomposes EWP into two stages: ecological economy and economic well-being, which opens the "black box" of the ecological well-being conversion process. PCA-DEA, the network super-efficiency Epsilon-based measure (Network SEBM) model, and Geodetector are used to dynamically measure the EWP in the Three Gorges Reservoir Area (TGRA) from 2010 to 2020 and analyze its spatial and temporal characteristics and influencing factors. The results show that (1) temporally, the EWP in the TGRA shows an increasing trend from 2010 to 2020, but the overall level is low. Spatially, it shows a high pattern in the east and low in the west, and spatial differences are gradually decreasing; (2) ecological economic efficiency is significantly lower than economic well-being efficiency, and ecological economic efficiency is the main reason limiting the improvement in EWP in the TGRA. The ecological well-being situation of the TGRA is not optimistic; (3) there is an overall problem of excessive ecological input and insufficient per-capita GDP and well-being output in the TGRA, and decisions should be made according to local conditions; (4) the level of economic development has an EWP level that plays a dominant role and also has a greater relationship with the policy system, socioeconomic conditions, and natural environment.

Sustainability comparison of commercial Brazilian organic and conventional broiler production systems under a 5SENSU model perspective

This study aimed to evaluate the sustainability of a commercial organic broiler production system based on the concept of strong sustainability. Thus, the FIVE SEctors of SUstainability model (5SENSU) under a perspective of Goal Programming philosophy were used and the results were compared to a commercial convencional broiler production system. For the data collection, two case studis were carried out in a representative commercial organic broiler production system (UPrO) and commercial conventional broiler production system (UPc) in the state of São Paulo from October/2020 to June/2021. The environmental and social dimensions were considered as providers of resources for the system and receivers of products and negative externalities. Environmental criteria were performed using the Emergy Synthesis, while economic criteria were performed using calculation models based on Economic theory. Furthermore, social criteria were performed using data collected on a farm. In the end, the broiler production system sustainability was compared using a general sustainability index by means of the Goal Programming philosophy. The results show a trade-off between animal welfare and economic and environmental costs. The lower stocking density in UPrO raised the animal welfare by providing more area/animal, but increased the resource consumption, GHG emission and the production cost. However, when social results were considered, UPrO showed more pathways to achieve a more sustainable commercial broiler production, as shown by the general sustainability index (43.2 and 49.4 for UPrO and UPc, respectively).

Spatio-temporal evolution of ecological environment quality in China from a concept of strong sustainability.

Based on the concept of strong sustainability, this paper builds a dynamic evaluation system on ecological environment quality from the concepts of ecological environment pollution and ecological environment management and puts forward the evaluation indexes including ecological environment pollution index (EPI), ecological environment management index (EMI), and ecological environment quality index (EQI). On this basis, kernel density estimation, Markov chain, Theil index, and dynamic SDM are used to reveal and explain the spatio-temporal evolution of ecological environment quality in China. The results were as follows. Overall, the EPI is decreasing while EMI and EQI are on the rise. In the long run, there is low possibility of upward and cross-level transition for EPI and EQI. The differences of EPI, EMI, and EQI are mainly caused by the regional differences. The regional differences have been reflected in the value of EPI, EMI, and EQI. It has been shown that the internal regional differences are continuously narrowing and the inter-regional differences are expanding. The convergence speeds of EPI, EMI, and EQI are 13.77%, 23.80%, and 9.69%, respectively. In the regional convergence test, different regions have shown different convergence speeds.

Menadžment održivog razvoja sagledavan kroz prizmu imperativa očuvanja prirodnog kapitala

After explaining the content coverage and elementary explanation of the basic dimensions of the paradigm of sustainable development, the concept of sustainability is considered in the light of preserving the total amount of capital in the production process, assuming no technological change and population growth. The research task set in this way brought to the fore the extremely complex question of the substitutability of produced and natural capital (stocks of natural resources and carrying capacity of the environment). The answer to it is directly related to the concept of weak and strong sustainability. The concept of poor sustainability allows substitutability between produced and natural capital, provided that the total amount of available capital does not decrease. On the contrary, the concept of strong sustainability implies a special observation of produced and natural capital. It practically eliminates the possibility of replacing one form of capital with another in the production process and from the point of view of the development economy is the only acceptable option in the long run. If unlimited substitution between natural and produced capital is allowed, then natural resources will eventually be depleted due to the creation of produced capital.

Time for Science-Based National Targets for Environmental Sustainability: An Assessment of Existing Metrics and the ESGAP Framework

Despite the overwhelming scientific evidence on the ongoing degradation of the environment, there is a clear gap between the urgency of the environmental crisis and the policy measures put in place to tackle it. Because of the role of metrics in environmental governance, the way environmental information is translated into metrics is of utmost relevance. In this context, we propose criteria to assesses the suitability of environmental metrics to monitor environmental sustainability at the national level. After assessing well-known environmental metrics such as the Sustainable Development Goals indicators and the Environmental Performance Index, we conclude that countries still lack robust and resonant metrics to monitor environmental sustainability. In order to bridge this metric gap, we present the Environmental Sustainability Gap (ESGAP) framework, which builds on the concepts of strong sustainability, critical natural capital, environmental functions and science-based targets. Different composite indicators are proposed as part of the ESGAP framework. Through these metrics, the framework has the potential to embed strong sustainability thinking and science-based targets in nations in which these concepts are not currently sufficiently reflected in policies.

In quest of implementing degrowth in local urban planning policies

ABSTRACT This paper focuses on the intersection between degrowth and urban planning and contributes to a deeper understanding and a sharper concretisation of how a strong sustainability concept such as degrowth can be taken into planning practice. Taking the Swedish municipality of Södertälje as a case, this paper uses empirical material from interviews with municipal urban planners and urban planning policy. The findings put current planning in relation to degrowth ideas, gather insights about the possible role of planning actors in a degrowth transition, and includes proposals for how planning practice can facilitate a degrowth future. This study finds that integrating a degrowth approach in planning practice means that urban planning needs to be subordinated to overarching social and environmental goals. Producing urban planning that is measured and conditioned by overarching goals would most likely imply completely different ways of planning, and goal-oriented backcasting scenarios are suggested as a tool to overcome this challenge. This paper also gathers strategies, like Södertälje’s Cultivation Strategy, that can facilitate a degrowth transition within current planning practice.

How the Global Initiative Report's Indicators are Related to the Strong Sustainability Concept? - A Paraconsistent Approach

The pressure imposed by human-dominated systems on the natural environment and the search for more balanced social systems are current concerns worldwide. Among scales of attention and shared responsibilities, companies are also in the radar of and interested in to be more sustainable. An efficient way in disclosing information on companies' sustainability is through sustainability reports, such as the global reporting initiative (GRI) framework. Although recognized as an important alternative, the GRI is receiving criticisms about its ability in accurately express the meaning of sustainability. This work applies the paraconsistent annotated evidential logic (PAEL) on opinions of experts in the sustainability theme to verify whether the GRI indicators are aligned to the concept of `strong' sustainability. A survey applied to twenty-two experts from different field areas, backgrounds and work experiences on sustainability-related issues provided their beliefs and disbeliefs, in a quantitative way, about the ability of each of the 91 GRI indicators in expressing sustainability. Results show high dispersion (coefficient of variation $>$30%) among the experts opinions for 77 of the GRI indicators, in which the social category appears with the worst performance with its total 48 indicators with high dispersion. This is an indicative of different understandings by experts about the meaning of sustainability concept and/or the meaning and reach of GRI indicators in achieving sustainability. The PAEL reports that all three categories (economic, environmental and social) fall into the `paracomplete' region of the Cartesian unitary square's graph, indicating an inconclusive result about whether these three categories are able to capture and/or express the concept of strong sustainability. The overall performance (barycenter with beliefs of $\mu =0.26$ and disbeliefs of $\lambda =0.17$) also fall into the paracomplete region, rejecting the initial hypothesis that GRI may show strong sustainability. Recognizing the increasing importance of sustainability reports, this work contributes in identifying and suggesting improvements to the GRI developers on indicators that may better represent the strong sustainability and achieve its main goals. GRI's framework should be based on a clear sustainability model and provide through a simple, fast and understandable way, information about the purposes of each indicator. Focus for improvements should be especially directed to: EC4-6; EN18, 20, 21 and 34; LA2, 4, 5, 7, 8, 11, 12, 14; SO3-8, 11; PR1-5, 7-9; HR3, 8-10.

Sustainability Assessment in Manufacturing under a Strong Sustainability Perspective—An Ecological Neutrality Initiative

The concept of strong sustainability establishes ecosystem conservation as the basis for socioeconomic development. Despite the increase in the number of studies on this subject, the qualitative approach used in studies on strong sustainability makes the introduction of this theme difficult in the industrial context. The absence of a model of sustainability evaluation in manufacturing based on the concept of strong sustainability was the gap identified by this research. The objective of this study was to develop a model that embeds strong sustainability within the sustainability assessment of manufacturing companies. The research used survey methodology to obtain the opinion of experts on the relevance of sustainability metrics. Information collected from experts was used to calculate the weights of indicators and of the participation of each dimension in strong sustainability. The results indicated that strong sustainability consists of 48% of environmental, 29% of social, and 23% of economic factors. The model has been applied in a study of multiple cases in factories in the automotive sector, two in Brazil and two in Italy. The results revealed that the four companies were rated regular in the strong sustainability scale. However, the sustainability performances of the companies showed different patterns over five years. Furthermore, analysis of the individual performance of the dimensions showed that the economic growth of the two Brazilian factories was superior to the socio-environmental development. The result of the Italian units emphasized different priorities. A firm reached the best result in environmental performance and the other one on the social dimension.

Challenges in the achievement of a Net Zero Carbon Built Environment – A systemic approach to support the decision-aiding process in the design stage of buildings

By limiting global warming to 2°C, the climate goals set by the United Nations in 2015 (Agenda 2030) will clearly be missed. The shrinking of our GHG budget has shown that the implementation of a weak sustainability concept - i.e. equal consideration of all sustainability dimensions (environmental, economic and social) - is not sufficient to meet the requirements of the Sustainable Development Goals (SDGs). Based on the strong sustainability concept - i.e. focusing on the environmental dimension of sustainability - this article highlights the challenges in the achievement of a Net Zero Carbon Built Environment by the implementation of a systemic design model in the early design stage of buildings. The visualisation of individual planning practices and their systemic behaviour in relation to other planning practices respectively to the SDGs support planners to manage the complexity and to reduce the additional effort within the implementation of sustainability aspects in the early design stage of buildings. Next to the visualisation of the environmental impacts of planning practices, the effects on other SDGs can be highlighted. Furthermore, the planner is supported in the decision-aiding processes in the early design stage. With the application of the systemic design model and the implementation of identified planning practices the contribution to the fulfilment of Agenda 2030 increases.

Integrated multi-criteria decision making methodology for pumped hydro-energy storage plant site selection from a sustainable development perspective with an application

Pumped hydro-energy storage (PHES) development involves heavy investment with stringent environmental and social requirements. Therefore, selecting the best site is a key influencer of the plant's ability to sustainably provide the expected benefits throughout its whole lifecycle. An important contribution could be provided by developing specific tools for improving decision accuracy while addressing the issue of sustainability through the decision-making process. In this view, this study aims to propose a decision-making model for selecting the best alternative from a number of predetermined PHES candidate sites, in a perspective of sustainable development. The approach is based on the identification of decision factors and criteria, and the use of multi-criteria decision-making (MCDM) techniques such as the analytic hierarchy process (AHP), rating scales and fuzzy logic-based scoring systems, and the ELimination and Choice Expressing REality (ELECTRE) III. These methods are comprehensively selected and combined to deal with the heterogeneity of the information and the vagueness of human preference and, to operationalise the concept of strong sustainability. Its practicality and efficiency was successfully tested on a set of eleven PHES candidate sites in Western Cameroon. As result the five best alternatives to be considered in the framework of the country's sustainable power generation policy were suggested in descending order of priority: (1)-Enep, (2)-Mbatu-dam, (3)-Benakuma, (4)-Bamendjin, (5)-Mentchum.

« Nous n’avons jamais été “soutenables” : pourquoi revisiter aujourd’hui la notion de durabilité forte ? »

Constatant l’échec de 30 années d’une approche procédurale du développement durable, Jacques Theys – dans cet entretien réalisé avec Clémence Guimont à l’été 2018 – plaide pour le retour à une soutenabilité forte qu’il définit comme la reconnaissance de limites absolues à l’action, mais circonscrites aux risques majeurs et aux impasses critiques pour les générations futures. Il en explicite les conséquences pour nos relations à la nature – irréductible à des fonctions – et l’articulation avec une approche substantive du développement durable – dont il rappelle les composantes. Revenant ensuite sur l’histoire, il montre dans quelle mesure cette conception forte a été ou pas présente dans les politiques publiques passées ou la prospective et s’interroge sur les conditions qui pourraient la rendre plus acceptable dans le contexte actuel.

Spatio-temporal characteristics of coupling coordination between green innovation efficiency and ecological welfare performance under the concept of strong sustainability

Spatio-temporal characteristics of coupling coordination between green innovation efficiency and ecological welfare performance under the concept of strong sustainability

Arte y Sostenibilidad. Respuestas Artísticas ante el Colapso

Theories about the collapse of contemporary societies have aroused increasing interest in recent years. Similarly, the environmental discourse has entered strongly into contemporary art, not from the naturalist or ecological approach of aforetime, but from the political ecology. Art, like other areas of knowledge, questions possible alternatives to collapse in terms of sustainability. However, given that there are two interpretations of the term sustainability, a weak one (the institutional one) and a strong one (the one defended by political ecology), it is relevant to clarify the implication of artistic projects in this sense. In the first part of this article, the scenario of the collapse of contemporary western society is presented and a parallelism with geological instability processes is established, in the context of an artistic research. Next, the types of responses to collapse are analyzed, based on ecological economy and political ecology concepts, and examples of artistic proposals are presented for each type of response. This analysis concludes on the role of contemporary art in the transition towards a sustainable society, as well as the convenience and urgency to promote artistic proposals that are framed in the concepts of strong sustainability.

Analysis of Regional Difference and Spatial Influencing Factors of Human Settlement Ecological Environment in China

The importance of regions in shaping sustainable economic growth trajectories has been the subject of extensive research in recent years. When sustainable growth has been investigated in developing countries, a particular focus has been on China’s unsustainable development approach, which is characterized by high energy consumption and high pollution. Crucially, most of the research so far has focused on topics concerning ecological environment improvement. However, little is known regarding how the quality of human settlements environment can be accurately measured in terms of the concept of strong sustainability at the regional level. This study investigated human settlement environmental quality across 30 provinces in China from the perspective of strong sustainability and attempts to shed light on its spatial influence factors. Estimates are presented using a projection pursuit method. The results reveal that the quality of human settlement ecological environment declined over the period 2002–2014 with a significant geographical disparity in index performance. The results also suggest an observable spatial effect. The energy structure, energy intensity, and environmental control in a province not only have significantly positive effects on ecological quality of a province itself, but also bring spillover effects on its neighboring provinces. These three factors are also important in determining human settlement ecological quality in China.
