  •   Free full-text access Open AccessAssessing smallholder farmers' perception of value creation and appropriation in sustainable production
    ( Free Full-text Access ) CC-BY-NC-ND
    by Luiz Carlos Demattê Filho, Ícaro Célio Santos de Carvalho, Cecilia Mitie Ifuki Mendes, Rafael Araújo Nacimento, Luciana Marques Vieira 
    Abstract: Market opportunities and improved demands for sustainable production and consumption highlight the importance of engaging smallholder farmers. This study aims to understand the transition towards sustainability through the perception about the value created and appropriated of small poultry farmers who supply a company that practices Nature Farming, in a vertical integration system. The authors adopted a system of indicators (Ambitec-Agro, assessment of the impact of technological innovations in agriculture) and used content analysis software (ATLAS.ti) to assess farmers' perceptions. The results suggest that the transition to sustainable production creates capacities to add value, mainly from social and economic perspectives. In addition, the relational value has a strong influence on this dynamic. The study contributes by proposing an application of methodology based on mixed methods to identify the perceptions of smallholder farmers about created and appropriated value in migrating from an input-intensive production to a sustainable system, offering opportunities for improvement in traditional supply chains.
    Keywords: poultry production; shared value; sustainable farming; value perception; relational value; vertical integration system.

  • Ant Forest - China's low-carbon consumption practices driven by a community currency mechanism   Order a copy of this article
    by Scott Y. Lin, Jiawei Zeng 
    Abstract: Ant Forest (mayi senlin, ) is a Chinese low-carbon consumption project initiated in the mid-2010s under China's personal carbon trading scheme. Based on its internal logic, this projects operation can be associated with a green movement within community currencies (CCs). This study investigates how Ant Forest (a type of CC mechanism) participates in, integrates, and even innovate the mechanism of environmental governance in China. From the CC perspective of a new economics centred on low carbon consumption, a multi-criteria qualitative evaluation tool with a set of indicators is adapted for the case analysis. The results show that the mechanism design of Ant Forest can develop a local circular economy, cultivate environmental awareness among citizens, build a low-carbon consumption community, create community interaction and pool social capital. The case of Ant Forest shows a bottom-up structure which enables public participation in China's environmental governance.

  • Enhancing fairness in the Paris Agreement: lessons from the Montreal and Kyoto protocols and the path ahead   Order a copy of this article
    by Donia Mahabadi 
    Abstract: Broad participation and compliance are key elements of any successful international environmental agreement (IEA). Notwithstanding the participation of a significant number of countries in the Paris Agreement, the level of compliance remains challenging. This article investigates the potential role of fairness in enhancing compliance under the Paris Agreement. It draws lessons from the Montreal and Kyoto protocols that could assist the Paris Agreement in incentivising countries. The article discusses the operationalisation of the common but differentiated responsibilities and respective capabilities (CBDR-RC) principle in different treaties. A formulaic approach to interpreting the CBDR-RC principle and the imposition of restrictions on non-compliant parties could be effective ways of promoting compliance with the Paris Agreement. Besides, market-based solutions are considered as economic approaches to incentivising countries to meet the climate target. The importance of market-based solutions is supported by the findings from a worldwide survey among international delegates negotiating the Paris Agreement.
    Keywords: international environmental agreements; IEA; Paris Agreement; carbon market mechanisms; fairness; compliance; common but differentiated responsibilities and respective capabilities; CBDR-RC.

  • A comprehensive economic impact assessment framework with some examples from the open cut and underground coal mining in India   Order a copy of this article
    by Galina Williams 
    Abstract: Economic impact assessment (EcIA) is an important part of a broader environmental impact assessment (EIA) process. However, EcIA has not been used to its full potential. This paper suggests a comprehensive framework of projects’ impact assessment which utilises two complementary techniques such as risk assessment (RA) and regional impact analysis (e.g., input output analysis) of alternative investments in an extended cost benefit analysis (CBA). Types of impacts that warrant an inclusion of RA in EcIA are discussed. The extension of regional impact analysis could assist in increasing positive impacts from proposed projects for local economies. Comprehensive EcIA could help to improve overall EcIA of projects especially those projects that might be potentially damaging for the environment and communities, although they would bring employment and income in the regions. Qualitative discussion using some examples from coal mining in India is provided.
    Keywords: economic impact assessment; EcIA; regional economic impact analysis; risk assessment; cost benefit analysis; CBA; input output analysis; India; environmental impact assessment; EIA.

  • Fabrication of industrially feasible zeolite membrane for the removal of hexavalent chromium   Order a copy of this article
    by R. Vinoth Kumar, Ashim Kumar Basumatary, G. Pugazhenthi 
    Abstract: The present study proposed fabricating an industrially feasible zeolite membrane on an indigenously developed inexpensive tubular ceramic substrate. A type of zeolite framework, Faujasite, was deposited on the substrate using source materials, such as alumina and silica, by hydrothermal treatment. The membrane was characterised by XRD, FESEM, zeta potential, and contact angle analyses. Distinguishable physical and structural characteristics of the zeolite membrane from ceramic substrate substantiated a formation of the composite membrane. Further, the potentiality of the membrane was assessed on the removal of hexavalent chromium from synthetic wastewater at various operating parameters in a crossflow system. The prepared membrane offered a maximum chromium removal of 82% with a flux of 5.05 x 10-5 m3m-2s-1 at the operating conditions of 1,000 ppm concentration, 345 kPa pressure, and 1.11 x 10-6 m3s-1 crossflow rate. The membrane revealed its essential employment by providing a higher flux with better rejection than other membranes applied in chromium removal.
    Keywords: Faujasite; hydrothermal treatment; zeolite membrane; chromium removal; contact angle; tubular membrane; Indian clays; low-cost membrane; zeta potential; composite membrane.

  • The blue bioeconomy the creation of a healthy fish farming business ecosystem   Order a copy of this article
    by Tero Leppänen, Vesa Lind, Henna Longi, Harri Haapasalo, Pekka Tervonen 
    Abstract: Customers expectations for speed, reliability and convenience are growing relentlessly. Therefore, companies need to distance themselves from traditional supply chain thinking and instead consider value nets, value networks and business ecosystems composed of several companies and multiple interlinked value chains. In this study, the concept of business ecosystems and their applicability have been examined in the context of bioeconomy. The objective of this paper is to describe the creation process of a healthy bioeconomy business ecosystem which was analysed via a descriptive and participatory case study. The case bioeconomy business ecosystem was created based on value networks with a heavy emphasis placed on the principles of the circular economy. This study concludes that there are four key aspects to consider in the creation of bioeconomy business ecosystems: the significance of market pull, the importance of physical proximity, the higher relevance of strong relationships and avoiding compromises that weaken process efficiency.
    Keywords: bioeconomy; business ecosystem; circular economy; ecosystem health; fish farming; industrial side stream; industrial symbiosis; value network.

  • Can renewable energy microfinance promote financial inclusion and empower the vulnerable?   Order a copy of this article
    by Andrea Gatto 
    Abstract: Energy microfinance is a promising asset for ensuring access to finance and electricity for the poor and women living in rural areas. Targeting vulnerable categories, renewable energy microfinance tools aim to promote sustainability and resilience policies to foster sustainable energy and ecological transitions. This research note explores the role of energy microfinance policies in facilitating virtuous loops for empowering the vulnerable, enhancing entrepreneurship, fighting poverty, and promoting social inclusion and environmental protection - as prescribed by the sustainable development mandate. Examining the microfinance-renewable energy-vulnerable nexus, the paper proposes a conceptual contribution and fungible development policy recommendations, sketching the main drivers of this linkage. To this end, a critical review of existing publications and successful world experiences is proposed. The analysis finds out a relevant potential for energy microfinance, whereby renewable energy expansion can be a strong player in shaping fresh microfinance strategies and prospects, providing ecological, social, economic and governance benefits and new research, policy, and practical agenda.
    Keywords: vulnerable; renewable energy; microfinance; energy policy; sustainable development; women empowerment; poverty alleviation; entrepreneurship boosting.

  • Is financial development good for ecological footprint? A Bayesian multilevel mixed-effects analysis in ASEAN countries   Order a copy of this article
    by Nguyen Tien Long, Bui Hoang Ngoc 
    Abstract: Improving per capita income and environmental protection are two crucial goals of macro-economic planning policies, especially in emerging countries. This study aims to investigate the impact of financial development on the ecological footprint in ASEAN countries from 1995 to 2016. The empirical results of the Bayesian multilevel mixed-effects analysis show that financial development has a moderately positive effect, whilst economic growth and urbanisation have a strongly positive effect on ecological footprint. These findings support the view of “more money, more control” to achieve sustainable development goals in ASEAN. Based on empirical results, the study suggests that the ASEAN countries should allocate financial resources to encourage the application of eco-friendly technologies, and improve environmental regulatory standards, including the introduction of environmental taxes, defining public property rights.
    Keywords: financial development; ecological footprint; economic growth; Bayesian analysis; ASEAN.

  • Scenario-based evaluation of integrated urban water management framework: a decision making approach   Order a copy of this article
    by Satya Prakash Maurya, Anurag Ohri, Prabhat Kumar Singh, Ramesh Singh 
    Abstract: n general, urban water management has been viewed as an exercise of meeting the domestic and industrial water demands from surface water and ground water sources. Nevertheless water-based development planning requires realistic estimation of balance between supply and demand within the geographical boundary. Recently, water management system is facing challenges of sustainable development goals (SDGs) in urban water sector. In the present paper an attempt has been made to review the various frameworks and systems developed for evaluating sustainability of an integrated urban water management (IUWM). Further, a computer application-based conceptual framework has been developed as a decision support system for integrated urban water management (DSS_IUWM) taking urban water management of Varanasi City (UP, India) as a case study. With the combination of available alternate water supply in the city, a scenario-based urban water balance has been evaluated. The study indicates that urban water balance (UWB) of Varanasi City is under unsustainable water condition with a negative value of 97 MCM. The study finally reports that a water sustainable condition in Varanasi City may be achieved through augmentation of storm water (55.4 MCM) management or reduction in fresh water demand through reuse of reclaimed water (36.5 MCM).

  • Evaluating a tool for the practice of corporate social innovations: a survey of Brazilian companies   Order a copy of this article
    by Marcelo A. Dionisio, Eduardo Raupp De Vargas 
    Abstract: To help reduce inequality, businesses are turning to corporate social innovations (CSI) to achieve both business results and social value. This study aims to evaluate and validate the CSI framework proposed by Mirvis and Googins as a tool for practicing CSI. We based our study on a survey conducted with Brazilian companies that participate in the UN Global Compact, the largest corporate sustainability initiative in the world to mobilise companies and stakeholders to do business responsibly, including 142 answers out of a sample of 609 companies. The data were analysed through a structural equation modelling (SEM) conducting confirmatory factor analysis (CFA) of the CSI framework to confirm the correlation between the five constructs, therefore establishing the validity of this framework as a tool for the practice of CSI. We expect to offer both a theoretical and a practical contribution by reinforcing the relevance of the CSI concept along with testing and validating the CSI framework as a tool to help evaluate, analyse, and implement CSI initiatives, advancing its practice and promoting the CSI concept.

  • Precise pollution control in new urban development areas: a case study from China   Order a copy of this article
    by Cong Wang, Yingchun Hao, Jidong Yao 
    Abstract: To overcome the difficulty of pollution control, it is necessary to investigate and implement a more precise and effective pollution control model. This paper examines the implementation of precise pollution control in Beijing’s Shunyi District. Through field research interviews and data collection, we conclude that the current implementation status of precise pollution control is a grid-based governance model with precise identification, accurate positioning, and refined management of environmental pollution. Certain technical difficulties in the precise identification of pollutants, the single structure of the main body for the precise location of pollution sources, and the need for the level of precise management to be strengthened are all part of the current problem analysis. Our suggestions include improving the scientific and technological capability of precise identification, improving the main structure of precise positioning, and fortifying the construction of a refined management system.

  • Impact of environmental and economic determinants on life expectancy: a sustainable development exploration in Sino-Pak from 1965 to 2020   Order a copy of this article
    by Hafiz Syed Mohsin Abbas, Aisha Azhar, Ahmad Ali Gul 
    Abstract: This study comparatively examines the impact of environmental, economic, and fiscal determinants on health well-being (life expectancy-LE) and social development in Sino-Pak. The present study uses LE at birth to proxy health well-being and the dependent variable. At the same time, carbon dioxide emissions (CO2) and gross domestic product per capita (GDPpc) as independent variables from 1965-to-2020, and current health expenditures per capita (CHE) is moderator variable from 2000-to-2020. OLS Statistics and graphical demonstrations show that CO2 emissions negatively affect the LE in Sino-Pak throughout the selected period while GDPpc has improved the LE in both countries. Adding a moderator role shows that CHE has played a promising role in China compared to Pakistan for life quality and sustainable development Goal 03. The study concludes that the Pakistan Government should adopt effective fiscal and administrative policies from China for better implementations and effective health well-being to achieve the SDG.

  • Ecological assessment of low carbon design of garden based on optimal BP neural network   Order a copy of this article
    by Min Yu, Yahui Zhang, Fangrong Yang, Panpan Jiao 
    Abstract: The contemporary ecological effect evaluation methods are mostly applied to a number of building industries in large municipal areas, and the ecological evaluation criteria for small area-wide buildings such as gardens are not very clear, leading to a lack of relevant evaluation guidance for garden design and architecture. The error of the proposed model is compared with the traditional algorithm, and the application effect of the model is analysed with the actual garden samples. The experimental results show that compared with the traditional BP neural network, the three output errors of the back propagation-genetic algorithm neural network model are reduced by 7.1%, 4.09% and 2.6%. At the same time, the low carbon design of the gardens reduced the concentration of SO2, NO2 harmful gases in the air of the town area by 0.193 mg/m3 and 0.263 mg/m3, respectively.

  • Varied perceptions of environmental impacts from informal public transport hubs in two sub-Saharan African cities (Nairobi and Ibadan)   Order a copy of this article
    by Vincent Onyango, Adebola Olowosegun, Dumiso Moyo 
    Abstract: This paper explored perceptions of the environmental impacts of informal public transport (IPT) in Ibadan, Nigeria and Nairobi, Kenya. Based on a questionnaire survey supplemented by exploratory factor analysis the results revealed unanimous agreement that IPT hubs and the infrastructure around them are perceived as having adverse impacts on local people and their environment. There exist statistically significant differences on the perceptions, including the latent factors underpinning them, at city level and across respondent's backgrounds. The findings imply significant scope for urban planning practice and policy-making to find systematic methods to integrate the knowledge about IPT's perceived environmental impacts, from all urban citizens, as a means to pro-actively enhance their rights and inclusiveness. This will ameliorate a planning culture that often ignores the realities and concerns of the marginalised.

  • Assessment of issues related to international trade and environmental impacts (emissions): an analysis for Brazil   Order a copy of this article
    by Weslem Rodrigues Faria, Vinicius de Almeida Vale, Fernando Salgueiro Perobelli, Admir Antonio Betarelli Junior 
    Abstract: This study is aimed at evaluating the impacts of the Brazilian trade structure on the amount of emissions, that is, at identifying the main trade links of Brazil in terms of CO2 emissions. We have considered two simulations through a global computable general equilibrium model - GTAP-E, calibrated with 2011 data. The first simulation specifies an incentive of 10% in the form of subsidies to Brazil's world exports to all sectors and regions. Analogously, the second simulation specifies a reduction of 10% in import tariffs for all sectors and regions of Brazil. The main results indicate that incentives to exports and imports would increase the emissions in Brazil and in most other regions. Firstly, because of the increase in the economic activity level of those sectors that use energy products more intensely as intermediate inputs, such as the transport sector. Secondly, because of the relative cheapness of foreign products, which would facilitate the purchase of energy inputs by Brazil. The main CO2 emission channels of the Brazilian international trade are with the rest of Europe and Argentina.

    by Shaharyar Brohi, Saima Kalwar, Irfan Ahmed Memon, Rabia Gill, Tarique Ahmed Khuhro 
    Abstract: MSWM is a significant issue in developing countries worldwide. The research aims to determine the problems and total/per capita waste generations and address some of the research shortage regarding MSWM in the Dadu. A structured close-ended questionnaire survey has been used, whereas interviews have been designed to ask officials regarding the MSWM. SPSS and ArcGIS software were use for the analysis of data. To evaluate the policies designed for MSWM and the study area's existing situation, the 'wasteaware' benchmark indicator framework technique is used. The results revealed that the MSW generation is 117 tons/d, which equals 0.62 kg/cap/day and illustrates the weak system. The inhabitants of Dadu MC generate 59% organic waste. It has been observed that all services of MSWM are provided by the public sector, with zero contribution from the informal sectors, and require improvements in management and physical infrastructure.

  • Greenwash, show your true colours: how verbal and visual messages influence consumers' perception?   Order a copy of this article
    by Kenny Basso, Jandir Pauli, Priscila Cerutti, Marcia Perin, Vitor Francisco Dalla Corte, Leila Dal Moro 
    Abstract: There is a gap between information on green products or cleaner production presented by the companies using verbal and visual messages and the consumer's perception. In this respect, the current research aims to verify how verbal and visual messages differently influence consumers perceptions of greenwash in an advertisement. A single factor experiment was designed. The results indicate that people exposed to the text format presented a lower elaboration (M = 3.75) than the subjects exposed to the image format (M = 4.91). The communication through an image created a more suspicious and negative word of mouth about the text format. In this way, an image may require a level of cognitive effort that can harm the greenwash perception.

  • Integrating fuzzy multi-criteria analysis for sustainable configuration of an on-grid hybrid renewable energy system: case study of Tunisia   Order a copy of this article
    by Zainab Koubaa, Mohamed Ali Elleuch, Ahmed Frikha 
    Abstract: Around the world, the tendency to integrate hybrid renewable energy sources (HRES) is becoming more popular due to sustainable electricity supply. However, determining the best sizing is a complex problem. Most existing decision aid tools to evaluate this design only consider the economic aspect. The use of just one criterion for determining the most appropriate HRES has been considered insufficient in terms of sustainability. To overcome this gap, this paper develops a multi-criteria decision making (MCDM) to obtain sustainable and resilient design of grid HRES for the electrification. Then, we made use of fuzzy multi-attribute decision making (FMADM) and multi-objective decision making (FMODM) by considering conflicting objectives aiming in elaborating a sustainable configuration of HRES. The proposed methodology was tested and validated with a real case study in Rades, Tunisia. The results highlight that the selected HRES not only ensures an economical system but also provides environmental and social advantages.

  • A GIS-based green infrastructure planning framework for water sensitive spatial planning   Order a copy of this article
    by Anju John, Anjana Bhagyanathan 
    Abstract: Green infrastructure (GI) as appropriately allocated land-uses in areas that are meant for inundation during intense rainfall, to encourage percolation and thereby reduce runoff is an important aspect of water-sensitive spatial planning. For tropical belts that combine high population density, rainfall, and landscape change due to rapid urbanisation, this is of paramount importance. The paper attempts to lay out an ecological planning framework for flood risk reduction through GI delineation. Multi-criteria decision analysis that takes into account meteorology, geology, geomorphology, surface-water hydrology, soils, and land-use land-cover patterns is being adopted. Physiographic division of river basin is considered the primary organising factor for the framework developed. The method is demonstrated using a typical watershed in Kerala that has witnessed a widespread loss of lives and property during subsequent floods. This framework will have applications in urban and regional planning, nature conservation fields, water-sensitive spatial planning, and climate change resilience planning.
    Keywords: green infrastructure planning; water-sensitive spatial planning; site suitability analysis; multi-criteria decision analysis; land-use land-cover change; runoff characteristics; Kerala flood 2018; Chaliyar river basin.

    Abstract: Renewable energy sources mostly suffer from their fluctuating and intermittent nature, which causes them to be restructured in the form of hybrid energy systems. In this paper, a two-stage optimal scheduling strategy for hybrid energy systems containing wind, solar, and energy storage systems along with conventional sources is presented. In the first stage, the imbalance cost in wind energy integrated systems is minimised with complementary renewables, i.e., solar, and further with different types of energy storage systems. In the second stage, the energy arbitrage facility of the electricity market is incorporated into the hybrid energy system for profit with imbalance mitigation using hybrid energy storage. The modified IEEE 30 bus system with a 35 MW wind farm and a 1 MW solar PV system is considered here. Results were obtained using the moth swarm algorithm (MSA) and verified using the artificial bee colony (ABC) algorithm.
    Keywords: wind farm; solar PV; imbalance cost; energy arbitrage; energy storage system; hybrid energy storage system.
