Green and blue infrastructure: Means of reducing surface temperatures in the urban environment
by Jan Sedlá?ek, Martin Hais, Kristýna Pouchová
Abstract: Climate change may accelerate the Urban Heat Island (UHI) effect with many consequences for the well-being of human populations in cities. Green and blue infrastructures (GBI) are presented as a way to mitigate the UHI effect. In our study, the influence of GBI (primarily less studied types) on surface temperature (ST) was tested using a thermal camera. Various types of GBI (e. g. tree shade and lawn) and their combination were compared. The studied GBI, including less common forms such as containers with ornamental plants, green roofs and fountains, reduced daytime ST. Moreover, they reduced the thermal amplitudes of surrounding areas (up to 30 m). The results imply that besides larger GBI (e.g. parks, rivers) smaller structures may significantly decrease the UHI effect. We recommend a combination of both blue and green structures especially in street canyons and the use of green roofs and walls when the space for adding GBI is limited.
Keywords: surface temperature; urban climate; microclimate; urban heat island; green infrastructure; blue infrastructure; greenery; vegetation; green roof; green wall; fountain; well-being; tree shade; climate change; thermal amplitudes.
Small hydropower development in Ukraine under global climate change patterns: is state economic support sufficient?
by Tetiana Kurbatova, Iryna Sotnyk, Oleksandr Kubatko, Liudmyla Gorbachova, Borys Khrystiuk
Abstract: During the last years, significant changes happened in seasonal river hydrology in Europe due to climate change. Nevertheless, according to the presented analysis, the total water runoff for hydropower generation did not change. The last fact is an important policy implication for small hydropower promotion in Ukraine because it belongs to that region and has similar climate conditions. Having analysed the hydropower potential, the paper describes the main advantages and limitations of implementing small hydropower projects in Ukraine. The cost of electricity generated by a small hydropower plant in Ukraine is determined and compared with the current feed-in tariff. The calculations show that the feed-in tariff is 1.4 times higher than the electricity generation cost, making the implementation of small hydropower plants profitable for investors. Since the state provides sufficient economic support for this sector's development, the financial and non-economic barriers significantly hinder small hydropower plant deployment are considered.

An urban ecology approach to land-cover changes in the Adyar sub-basin: comparative analysis of NDWI, NDVI and NDBI using remote sensing
by Mythili Madhusudhan, N.K. Ambujam
Abstract: The impacts of urbanisation may be social, environmental or ecological. In this paper, studies on the characteristics of urbanisation and its impacts in Chennai, India, particularly the South Chennai region are discussed. The study involves use of Landsat images and comparison of normalised difference vegetation index (NDVI) corresponding to mentioned dates in 1977, 1998 and 2018. Also, the normalised index for water (NDWI) and the built-up index (NDBI) are mapped and compared for the same dates. The results show that for the years 1977, 1998 and 2018, the difference between the maximum and minimum values of NDVI are found to be 1.609, 1.026 and 1.288, of NDWI are found to be 1.802, 1.239 and 1.518, and of NDBI are found to be
1.785, 0.993 and 1.036, respectively. The trends in indices for the dates considered are found to correspond to human activity and the significance of these changes is discussed.
Keywords: urban ecology; normalised difference vegetation index; NDVI; normalised difference water index; NDWI; normalised difference built-up index; NDBI; Landsat; remote sensing; land use; South Chennai.
Study of the waste disposal effect on air quality: the Italian case study
by Nicoletta Lotrecchiano, Renato Ciampa, Aristide Giuliano, Daniele Sofia
Abstract: The environmental status is defined by the combination of information about air pollution and waste production and management. This paper aims to compare the percentage of waste disposal in Italy with air quality. For each Italian region, the percentage of waste disposal and air quality were analysed. For some more interesting regions like Trentino South-Tyrol, Piedmont, Veneto, Lombardy, Lazio, Marche, Umbria, Abruzzo, Campania, Basilicata, Apulia, and Sicily relationship were highlighted taking into account citizens concerns about air quality. It is clear, after analysing the data, that in 2012-2017 the environmental awareness of the Italian population has increased with a consequent increase in the percentage of waste disposal and with the improvement of air quality.
Keywords: Italy; waste disposal; air quality; environment; particulate matter; NO2.

by Ikeu Tanziha, Sri Awalia Febriana, Katharina Oginawati, Yessi Crosita Octaria, Risti Rosmiati
Abstract: This study aimed to determine the regional sustainability of the healthy Batik Village from social, economic, and ecological perspectives. It was conducted in July 2019 in Kulon Progo, Special Region of Yogyakarta. Furthermore, the survey data were analysed using the RAPFISH ordination technique through the multidimensional scaling (MDS) method. The index and regional sustainability status of the healthy Batik Village were accessed using these methods. It also identified sensitive attributes affecting the sustainability index of social, economic, and ecological dimensions through the leverage analysis. The analysis results showed that the ecological dimension had the lowest index value (23.9) or in the poor category. The social and economic dimensions showed sufficient status with indices of 62.92 and 61.13, respectively. The policy implications for improving the sustainability status from sufficient to good need to manage the sensitive attributes of these three dimensions.
Keywords: regional sustainability; multidimensional scaling; MDS; healthy batik.
Bio FT-diesel in the European maritime sector: a technical economic valuation of straw crops potential
by Vinicius Andrade Dos Santos, Antonio A.T.G.Portugal, Patrícia Pereira Da Silva, Luis M. V. Serrano
Abstract: The present study has as an objective exploring the lignocellulosic residues from European agriculture as an energy source for the production of bio Fischer-Tropsch diesel (Bio FT-Diesel) as a low carbon alternative to be used in the European maritime sector, based on a techno-economic methodology of residue collection combined with the production yield of FT-Diesel available on literature. It permitted us to find a potential production of 8.5 million tons (Mton) of biofuel across 11 countries, and the reduction of 26 Mton of CO2 annually. The study contributes to the understanding that the fuel could be only cost-competitive if the crude oil reaches values between 10.4516.91 /GJ. In addition, the low technology status of bio FT-Diesel production and the lack of biofuel standards to the maritime sector are limitations that can only be addressed with effective regulations added to research and development from collection to production and consumption.
Keywords: maritime transportation; agriculture biomass; Fischer-Tropsch diesel; decarbonisation,.
Green banking: a strategy for attainment of UN-Sustainable Development Goals 2030
by Syed Asim Ali Bukhari, Fathyah Hashim, Azlan Amran
Abstract: All over the world, countries are facing severe climate change and environmental degradation. Green banking has been developed and adopted as a banking ideology to reduce the adverse environmental impact of various polluting industries. The purpose of this study is to develop a multidimensional framework for green banking adoption which is in line with the United Nations-Sustainable Development Goals (UN-SDGs) 2030. Green banking can play an important part in the attainment of the UN-SDGs 2030. This study demonstrates the dimensions of green banking adoption that can be
adopted by banks in order to facilitate the environmental sustainability of the
country. The study proposes the framework for green banking adoption based on the natural resource-based view (NRBV) of the firm. The first-order constructs in the framework have been derived from the green capabilities proposed in NRBV of the firm. These reflective constructs lead towards the second-order construct of green banking adoption. The proposed framework is developed and justified on a theoretical basis and through secondary data.
Keywords: green banking adoption; UN-SDGs 2030; green building; green audit; green financing; green capabilities; natural resource-based view; NRBV.
Implementing green infrastructure for stormwater management and combined sewer overflow control
by Lucas Niehuns Antunes, Arthur Rafael Medeiros De Araújo, Manuella Fagundes Bet, Sara Coimbra Da Silva, João Vitor Erlacher De Figueiredo, Betina Frigotto De Lima, Tabita Sonntag Manzoni, Layane Christine Vieira
Abstract: Green infrastructure has been used in many countries as a source control measure of stormwater runoff. Chicago is one of the many cities that have a combined sewer system and frequently faces overflows. This study proposes a stormwater management system along Chicago's riverfront. The area of green infrastructure to be studied (77,300 m2 ) is composed of wetland, pond and permeable pavement and was designed to collect, store, treat and discharge or reuse 23,620,000 litres of water. A 49.1% reduction in runoff has been determined for the wetland/pond system compared to the current scenario. The permeable pavement, in turn, infiltrated and stored, on average, 325,000 litres of stormwater daily. The stormwater collected from the pavement would be used for non-potable purposes, providing potable water savings up to 6.5%, and serving more than 13,000 people of the neighbourhood. The findings highlight the great potential of green infrastructure to improve stormwater management.
Keywords: green infrastructure; wetland; pond; permeable pavement; stormwater management; combined sewer overflow; CSO.
The circular economy for sustainable development: implementation strategies in advanced small open economies
by Lina Dagilienė, Jurgita Bruneckienė, Viktorija Varaniūtė, Mantas Lukauskas
Abstract: Sustainable development and circular economy (CE) policy perspectives are growing in importance. However, there is little empirical research about the implementation of a circular economy or a critical review of its indicators at the country level. Using an institutional approach, this paper explores CE implementation strategies in advanced small open economies (SOEs) in the European Union (EU). We used a principal components analysis (PCA) and a clustering analysis based on data from the EU monitoring framework for the circular economy, specifically 13 small open economies
from 2010-2017. The main findings reveal three CE implementation strategies correlated with CE development stages: integrated to value chain, focused on institutional compliance and fragmented. Surprisingly, we found no evidence for the expansion of CE-related sectors based upon persons employed, value added or gross investments. This topic deserves further investigation, with important implications for future research and policymaking.

From cleaner production to sustainability: multiple case studies in Uruguayan companies
by Florencia Kalemkerian, Silvia Lamela, Javier Santos, Martin Tanco
Abstract: Since the concept of cleaner production (CP) considers not only the environment but also the economic and social dimension, more scholarly attention is focused on studying the relationship of CP to sustainability. This research aims to present the main elements that contribute to successful CP implementation and sustainability in organisations. Eleven companies, mostly SMEs that adopted CP practices after a training course, were selected from different industrial sectors. The main results showed that the critical success factors most often cited for achieving successful implementation are commitment from top management and government support. Although some companies continue to implement sustainable practices, the majority apply CP only to comply with environmental laws, which results in a limited contribution to sustainability. Additionally, the analysed companies do not have standardised metrics to evaluate their sustainable performance, but CP serves as a guide to support their decisions. More effort is needed to make companies aware of the benefits of CP in other areas of organisations, and to integrate the three domains of sustainability when implementing CP practices.

Assessment of issues related to international trade and environmental impacts (Emissions): an analysis for Brazil
by Weslem Faria, Vinicius Vale, Fernando Perobelli, Admir 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 Brazils 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.
Keywords: International Trade; Emissions; Computable General Equilibrium Model.
Localised strategies and principles of good governance for the Sustainable Development Goals: where do the local authorities in Turkey stand?
by İhsan İkizer
Abstract: The Sustainable Development Goals have been set by the representatives of all nations on the Earth, for people, planet, prosperity and peace. It is accepted that cross-sectoral nature of the SDGs requires collective responsibility, multi-level collaboration among all stakeholders, with the participation of people, for whom these goals exist. This article has revealed that, among the 30 metropolitan municipalities in Turkey, where localisation of the SDGs and multi stakeholder local governance is rare, just a few of them have aligned their targets partially with those of the SDGs. Local authorities in Turkey do great jobs regarding many aspects of the 2030 Agenda; however, their works need a torch, in the form of a localised strategy of the SDGs, better governance and a sustainable, institutional mechanism for monitoring the progress. The motto of 'leave no one behind!' cannot be realised without full engagement of local authorities in this challenging process.

Varied perceptions of environmental impacts from informal public transport hubs in two sub-Saharan African cities (Nairobi and Ibadan)
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 respondents backgrounds. The findings imply significant scope for urban planning practice and policy-making to find systematic methods to integrate the knowledge about IPTs 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.
Keywords: informal public transport; IPT; environmental impacts; perceptions; Nairobi; Ibadan; urban planning.

by Abdul Ghaffar Tahiri, Irfan Ahmed Memon, Saima Kalwar, Noman Sahito, Gopal Das, Shaharyar Brohi
Abstract: Parks and recreational spaces play a major role in upgrading the living conditions of urban areas. Easily accessible public parks are a crucial aspect of sustainable urban planning. Objective is to assess the level of serviceability of public parks in terms of accessibility, and spatial distribution of neighbourhood and city parks. The data obtained from USGS Earth Explorer and Google Earth software, and was put in ArcGIS 10.2 software for creating land use land cover map of study area. Methods of buffer and network analysis used for accessibility analysis of public parks category-wise. The catchment area limit is set as 300 m and 800 m for neighbourhood park, and city park respectively. The results reveal the clear distinction in the availability of parks across the study area. However, study findings may help concerned authorities and stakeholders to the creation of standards for the delivery of parks and green spaces.
Keywords: public parks; accessibility; GIS; network analysis; buffer analysis.
Ant Forest - China's low-carbon consumption practices driven by a community currency mechanism
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.

Assessment of municipal solid waste management in the city of Dadu, Sindh, Pakistan
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 areas 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?
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 consumers 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.
Keywords: cleaner production; consumers; environment; greenwash; perceptions; sustainability.
Enhancing fairness in the Paris Agreement: lessons from the Montreal and Kyoto protocols and the path ahead
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
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.

Fabrication of industrially feasible zeolite membrane for the removal of hexavalent chromium
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
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?
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
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
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).

by Xavier Oña-Serrano, Oswaldo Viteri-Salazar, Juan José Cadillo Benalcázar, Xavier Buenaño Guerra, Maribel Alexandra Quelal-Vásconez
Abstract: In this study, an environmental approach is used to reveal pressures on natural resources caused by food waste and depicted through water, land and energy footprints. The purpose is: 1) to quantify food waste in households in the Metropolitan District of Quito; 2) to determine the environmental pressure of food waste on energy, water and land. Finally, an analysis of some initiatives for reducing food waste and policies applied to the supply chain of the products selected was performed. To that end, an online survey was carried out, and the responses were classified through a descriptive analysis to establish categories of food and the energy, water, and land footprints of rice and potatoes. The results and information presented here are expected to be valuable for generating or rethinking policies to make improvements in the food system to achieve Sustainable Development Goals.
