Sustainability Of Biogas And Cassava Based Ethanol Value Chains In Viet Nam

This report presents the results of the implementation of the GBEP indicators to two key bioenergy pathways in Viet Nam: cassava-based ethanol and biogas at household, farm and industrial levels. The environmental, social and economic impacts of these two pathways are discussed, and recommendations are provided on how to improve their sustainability, efficiency and competitiveness. This work provided Viet Nam with an understanding of how to establish the means of a long-term, periodic monitoring of its domestic bioenergy sector based on the GBEP indicators. Such periodic monitoring would enhance the knowledge and understanding of this sector and more generally of the way in which the contribution of the agricultural and energy sectors to national sustainable development could be evaluated. The implementation of the GBEP indicators in Viet Nam also provided a series of lessons learnt about how to apply them as a tool for sustainable development and how to enhance their practicality.

Anaerobic digestion is by far the most important technology for providing clean renewable energy to millions of people in rural areas around the world. It produces biomethane with anaerobic-digestate as a byproduct that can be used as a biofertilizer. In the context of energy consumption, more than 85% of the total energy consumed currently comes from non-renewable fossil resources. A wide variety of biowastes can be used as feedstocks for biogas production. Biogas technology can provide sustainable, affordable, and eco-friendly green energy along with useful byproducts. This book discusses the basics of biogas production and aims to address the needs of graduate and postgraduate students as well as other professionals through further evaluation of biogas production via case studies.

Sustainable Cassava: Production, Processing, Trade, Consumption and Waste Management Strategies presents viable approaches to promote sustainability in this globally important crop, enabling future generations to benefit. Providing key insights to enhance production while limiting environmental impact, this book provides readers with foundational understanding of growing and utilizing Cassava. Cassava (Manihot Mill. species Euphorbiaceae) is a staple crop in tropical and subtropical regions of the world with diverse food and non-food value. It is a principal energy source but may be fortified to provide improved nutritional status for consumers as well as for the production of value-added products. With the growing human population, there is a need to increase global production and efficiency in trade, diversify and ensure safe consumption, maximize utilization of all cassava processing wastes, and add value to the cassava production chain through sustainable practices Presented in three parts, the first addresses cassava diversity and distribution, sustainable production and cultivation practices, and root processing innovations of the crop. Cassava trade policies and economic value chains, food safety and use of cassava, and agro-industrial cassava products are addressed in the second part. The third part focuses on bioeconomy aspects, cassava waste quality assessment, toxicology, sanitary practices, environmental risk assessment as well as sustainable management strategies for cassava waste using biotechnological and industrial advances. Addressing the need for a unified and standardized approach for the trade, management, and utilization of cassava genetic resources, finished products, and cassava processing wastes, the book also explores policy and governance structure for addressing environmental and economic issues emanating from their use. In the lens of globalization, climate change adaptation and mitigation, and sustainable development, the contents of this book will promote the adoption of novel and advanced practices in cassava cultivation and production, harvest, use, and waste recovery or reduction and contribute to global cooling efforts. Presents best practices and ideas from around the world, including technological advances for Cassava production and use Focuses on sustainability throughout the lifecycle Provides insights translatable to other tuber crops for further enhanced sustainable food security

Bioethanol Production from Food Crops: Sustainable Sources, Interventions and Challenges comprehensively covers the global scenario of ethanol production from both food and non-food crops and other sources. The book guides readers through the balancing of the debate on food vs. fuel, giving important insights into resource management and the environmental and economic impact of this balance between demands. Sections cover Global Bioethanol from Food Crops and Forest Resource, Bioethanol from Bagasse and Lignocellulosic wastes, Bioethanol from algae, and Economics and Challenges, presenting a multidisciplinary approach to this complex topic. As biofuels continue to grow as a vital alternative energy source, it is imperative that the proper balance is reached between resource protection and human survival. This book provides important insights into achieving that balance. Presents technological interventions in ethanol production, from plant biomass, to food crops Addresses food security issues arising from bioethanol production Identifies development bottlenecks and areas where collaborative efforts can help develop more cost-effective technology

Biofuels global emergence in the last two decades is met with increased concerns over climate change and sustainable development. This report addresses the core issue of biofuel sustainability of biofuels and related feedstocks, drawing from a wide range of sustainability related studies, reports, policy initiatives. The report critically examines the economic, environmental and social sustainability dimensions of biofuels and review the major certification initiatives, schemes and regulations. In doing so, the report relies on extensive review of a number of country case studies covering a broad range of current biofuel-feedstocks systems. The report analysis clearly distinguish feedstock efficiency (in terms of biofuel yields per unit of land) from sustainability, especially under limiting resource (irrigated water) or sensitive areas (carbon stocks). Also, long run economic viability depend on the future policy support, technical innovations in biofuel systems, economics of biofuel supply and demand and trade-offs between food and energy uses as well as feedstock productivity gains. Biofuels can present both advantages and risks for environmental sustainability; the latter being often difficult to measure or monitor and may conflict with economic sustainability unless great strides in productivity gains are achieved. Social sustainability is the weakest link in current biofuel certification schemes owing to intrinsic local factors and as efforts target more few negative social impacts; much less focus is placed on inclusive processes that strengthen marginal stockholders participation and benefits. Biofuel certification schemes need to be more smallholder inclusive, perhaps through policy initiatives. Finally, poor developing countries, especially with abundant land and biomass production potential, need to prioritise food security and poverty reduction. In many cases, biofuel models that encourage small scale integrated bioenergy systems may offer higher rural development impacts. FDI-induced larger-scale biofuel projects, on the other hand, may be suitable in those situations where countries have sufficient industrial capacity, besides land and biomass potential, and when these biofuel projects can be fully integrated into domestic energy strategies that do not conflict with food production potential and food security.

In 2021, the United Nations Secretary-General will convene the Food Systems Summit to advance dialogue and action towards transforming the way the world produces, consumes and thinks about food guided by the overarching vision of a fairer, more sustainable world. The Secretary-General will also convene the High-Level Dialogue on Energy (HLDE) to promote the implementation of the energy-related goals and targets of the 2030 Agenda for Sustainable Development. Given the inextricable linkages between the energy and agriculture sectors, integrating the nexus perspective within the FSS and the HLDE is crucial to formulate a joint vision of actions to advance the 2030 Agenda for Sustainable Development and the Paris Agreement. In this context, IRENA and FAO have decided to jointly develop a report on the role of renewable energy used in food chain to advance energy and food security as well as climate action towards the achievement of Sustainable Development Goals and the Paris Agreement. While energy has a key enabling role in food system transformation and innovation in agriculture, its current use is unsustainable because of the high dependence on fossil fuels and frequent access to energy in developing countries. The challenge is to disconnect fossil fuel use from food system transformation without hampering food security. The use of renewable energy in food systems offers vast opportunities to address this challenge and help food systems meet their energy needs while advancing rural development while contributing to rural development and climate action.
