Integrated production of food, energy, fuels and chemicals from rice crops: Multi-objective optimisation for efficient and sustainable value chains

Solutions to neutralize greenhouse gas emissions of the rice value chain — A case study in China

Sustainable development concerns have been integrated into global value chains through the enforcement of sustainability standards, making the chains sustainable. Understanding the sustainability effects of sustainable value chains has been limited by the narrow focus on one standard, few larger comparative perspectives, methodological weaknesses, and diversity of contexts. This article analyses how sustainable coffee value chains contribute to sustainable development. Systematically, the study reviewed peer‐reviewed publications based on causal methodologies and primary data collected from Uganda, Kenya, Tanzania, and Ethiopia. The paper shows that sustainable value chains promote sustainable development, but their effects vary across sustainability dimensions and standards. Fairtrade has a higher contribution to social sustainability because it emphasizes social issues. Organic standards and the Rainforest Alliance also have a higher contribution to ecological sustainability because they emphasize ecological conservation. Sustainable coffee value chains have more contributions to social and ecological sustainability than economic sustainability because of the trade‐offs that ensues from conversion to sustainable value chains. However, combining standards reduces trade‐offs. The sustainability effects of sustainable value chains also vary across cooperatives because of their heterogeneity.

Multi-objective spatio-temporal optimisation for simultaneous planning, design and operation of sustainable and efficient value chains for rice crop

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.

PurposeThis paper aims to highlight the challenges and opportunities of sustainable global value chain governance, it demonstrates strong theoretical deficits in this field and offers new pragmatist conceptual perspectives.Design/methodology/approachThe empirical analysis is based on document analyses, 47 expert interviews and on field observations in Ghana, Africa.FindingsBased on an in-depth analysis of a US firm operating a fair trade value chain in an intercultural environment, the authors show that universalistic value chain-oriented governance instruments often fail because of strong institutional and cultural distances. Against the prevailing strategies of top-down management, the authors suggest a more bottom-up, pragmatist and collaboration-based approach to sustainable global value chain governance.Research limitations/implicationsThe results of an in-depth case study are not generalizable. Instead, they provide holistic insights into a so-far insufficiently examined field and an empirical fundament for further research on sustainable governance in global value chains. In particular, research on pragmatist, collaborative, dialogue based, bottom-up approaches of sustainable value chain governance will be of great value to further theoretical development of this field.Practical implicationsThis study is relevant to researchers and practitioners in the field of sustainable value chain governance. It reveals several misunderstandings about the effectiveness and impacts of sustainable governance in less developed countries and thus builds a foundation for better and more effective problem-solving approaches in international sustainable management activities.Social implicationsNontransparent supplier networks and (illegal) sub-contracting, as well as the strong influences of institutional, cultural and sub-cultural factors, make responsible value chain management a challenging task for any firm with international value creation activities. This leaves workers in local factories vulnerable to infringements of their fundamental human rights and the environment unprotected against long-lasting damages. Addressing these challenges and developing new solutions, therefore, can have strong impacts on the lives of workers in international supply chains.Originality/valueThe authors contribute, first, a differentiated empirical description and analysis of a sustainable value chain approach in a less developed country in Africa. Second, using an example of the field study, the authors highlight limitations of value chain-related governance theory based on a field study by illustrating the challenges and barriers and a lack of existing concepts concerning effective sustainable governance in global value chains. Third, the authors show different managerial responses to these cultural and institutional challenges between universalism and relativism, and, fourth, the authors suggest a more collaborative, bottom-up and pragmatist approach to sustainable value chain governance.

Mitigating Curtailment and Carbon Emissions through Load Migration between Data Centers

Energy-related activities are a major contributor of greenhouse gas (GHG) emissions. A growing body of knowledge clearly depicts the links between human activities and climate change. Over the last century the burning of fossil fuels such as coal and oil and other human activities has released carbon dioxide (CO2) emissions and other heat-trapping GHG emissions into the atmosphere and thus increased the concentration of atmospheric CO2 emissions. The main human activities that emit CO2 emissions are (1) the combustion of fossil fuels to generate electricity, accounting for about 37% of total U.S. CO2 emissions and 31% of total U.S. GHG emissions in 2013, (2) the combustion of fossil fuels such as gasoline and diesel to transport people and goods, accounting for about 31% of total U.S. CO2 emissions and 26% of total U.S. GHG emissions in 2013, and (3) industrial processes such as the production and consumption of minerals and chemicals, accounting for about 15% of total U.S. CO2 emissions and 12% of total ...

PurposeAgrifood value chains in developing countries are transforming into higher value markets which require sustainable practices, with smallholders playing a critical role. However, smallholders are a heterogeneous group which may have discrepancies in outcomes to meet sustainability standards. This paper aims to empirically investigate smallholders' heterogeneity towards sustainable value chain practice in developing countries.Design/methodology/approachEight key enabling factors of sustainable value chain transformation were used to explore smallholders' typology, then profiled, based on their socio-economic status and current practices. A quantitative method was applied in Indonesia's cashew sector with 159 respondents from the primary producer area on Madura Island. A combination of descriptive analysis, cluster analysis, cross-tab analysis and one-way ANOVA analysis was used in this study.FindingsFour types of groups were identified, each with distinct characteristics and arranged in priority order as follows: accelerator, progressor, inattentive and conservative groups. Interventions can be implemented on per clusters basis or based on potential similarities among clusters, depending on priority. It is noted that the pursuit of sustainable value chain practices by smallholders is not necessarily associated with high socio-economic status, as those with low socio-economic status may have a stronger inclination towards them.Practical implicationsThe paper enhances awareness of practitioners and policymakers regarding smallholders' heterogeneity in sustainable value chain practice. It enables more effective and focused interventions to support smallholders who require assistance in sustainable production and value-adding activities. Different smallholders' characteristics call for different assistance/intervention. Practitioners can recognise smallholders' characteristics that are more compatible with higher value markets and sustainability requirements to better integrate their practices. Policymakers must carefully develop short-term and long-term interventions based on the activities prioritised by particular traits to “hit the right button” for smallholders' practice development.Originality/valueThis study investigates the typology of smallholders towards sustainable value chain practices by using eight enabling factors and profiling them based on their socio-economic condition and current practices. Additionally, this study shifts the focus of typology exploration away from the traditional lens of farm sustainability to a larger perspective which encompasses sustainable value chain activities.

Enabling sustainable agrifood value chain transformation in developing countries

PurposeThe nature of farm animals in the marginalized group of people is varying hurriedly. Livestock is used to add to cash earnings and increase food security, hence helping as a vital component in the household’s source of revenue strategies, particularly at marginal planter’s level. The present study was conducted to assess the numbers of livestock farmers in the study areas, their livelihood options, the value chain of the farmers in different marketing channels and recommendation for the sustainable value chain of the livestock production cycle.Design/methodology/approachThe study precise the baseline condition of marginal livestock farmers for access to value chain activities in terms of inputs, outputs, support services, production, yield, income and enabling environment to enhance livestock farming in the study area. The study was conducted through stratified random sampling of the context using some research tools like in-depth interviews, household surveys, expert opinions and focus group discussions. Structured questionnaires were developed to address issues, such as current livestock farming practices, access to support services, capacity and income.FindingsThe study revealed that this particular context is lagging behind to establish goat value chain activities in the targeted areas. The farmers do not have basic knowledge of goat farming, and the value chain actors are not working properly. The support services are not appropriate to turn the goat farming production to a standard level. Value chain of livestock and livestock products and their goals are essential to develop an idea on learning, investment, market access, sales assurance and quality. Variation in institutional contexts of end markets is linked to different types of coordination and control of enabling environment throughout the chains.Practical implicationsLivestock is an integral component of the complex farming system in Bangladesh as it serves as not only a source of meat protein but also a major source of farm power services as well as employment. Strong private sector alliance along with public–private ventures can bring sustainable agriculture value chain development in these most vulnerable coastal communities in Bangladesh. Strengthening the weak financial structure, reducing power imbalances in the governance structures and low political intervention in community-level organizations, and resolving socio-cultural and environmental concerns are the major concerns on the development of value chains in Bangladesh.Originality/valueGeographical position and climatic condition of Bangladesh have made her coastal areas one of the highly productive areas for livestock production in the world. The study was conducted through qualitative and quantitative analysis, and after finding the authors recommended for sustainable value chain approach for livestock production to a marketing channel for improving the financial condition and self-employment for the communities.

Greenhouse gas (GHG) emissions reduction in the electricity sector: Implications of increasing renewable energy penetration in Ghana's electricity generation mix

Heterogeneity of the impact of energy production and consumption on national greenhouse gas emissions

Energy from waste (EfW) for nonrecyclable wastes is a suitable method of waste management and is important for renewable energy production. South Korea currently recycles 57% of household waste and landfills 26%. The remaining 17% is incinerated, mainly for heat production. In this study, the potential for energy production and reduction of corresponding greenhouse gas (GHG) emissions from municipal solid waste (MSW) in Korea was estimated without accounting for the lifecycle impact of waste management. The properties of the MSW were established from data available in national-scale waste surveys and reports. The potential of EfW for GHG emission reduction was calculated considering (1) the direct release of anthropogenic carbon, nitrous oxide (N2O), and methane (CH4); and (2) the reduction in indirect GHG emissions by fossil fuel displacement. CH4 emissions from landfilling were also estimated from biogenic carbon in waste. Applying the resulting emission factors to various EfW cases suggests that the current level of GHG emissions is significant but can be substantially reduced by increased use of EfW. A net reduction in GHG emissions can be achieved only by EfW with combined heat and power (CHP).
