An Innovative Accounting Framework for the Food-Energy-Water Nexus. Application of the MuSIASEM approach to three case studies 27 March 2014 Human wellbeing relies upon the availability and wise management of food, energy and water. The interconnections between these resources make clear that the management of each of them cannot be considered in isolation but in an integrated and holistic way. Inter-linkages should be considered also among different scales, between local and global processes of resources use, and between social and economic aspects of a society, in order to properly assess the impacts of new policies or interventions.

No 57 - Evidence-based assessment of the sustainability and replicability of integrated foodenergy systems 27 March 2014 Bioenergy when managed sustainably and efficiently can be an alternative energy source that helps reduce energy access problems. Rural and urban communities can benefit from increased access to energy, and therefore improved food security when bioenergy feedstock is produced guided by principles of sustainable production intensification and energy efficiency improvements are made by applying agro-ecological practices and locally adapted technologies.. To mitigate the risks of bioenergy production threatening food security and to harness the potential benefits of bioenergy productionFAO recommends appling good practices of bioenergy production from the onset. The production of bioenergy in Integrated Food-Energy Systems (IFES) is one of such good practices since these systems meet both food and energy demands.This publication presents an analytical framework which serves to screen different IFES options systematically and helps to define which IFES systems are sustainable and replicable. In concrete terms, this framework is envisioned to be a guidance document that allows its user to assess which factors make an IFES truly sustainable and which factors need to be considered when replicating such a system - be it a pilot project, a business innovation or a research experiment. Furthermore, it helps to systematically describe the potential contribution of IFES to sustainable agriculture and the growing bioeconomy, and to raise awareness among decision-makers about which factors can facilitate the replication of such innovative projects.While the concept of IFES builds on the principles of sustainable intensification and the ecosystem approach, it stresses the fact that the diversification of crop and livestock species can lead to a sustainable production of both food and energy feedstock, as long as relevant practices and technologies are locally devised and adapted. It further emphasises that energy efficiency can be reached in these systems when applying sound agr... [more]
No 55 - BIOSLURRY=BROWN GOLD? 12 September 2013 In recent years, there has been an increasing interest in anaerobic digestion of farm and household residues in many parts of the world. Smallholder biogas digesters and community biogas plants can be found all throughout Asia, but also progressively in Latin America and Africa. Anaerobic digestion produces two main outputs: biogas and bioslurry, the digestate or digester effluent. While biogas is used to produce energy, the large potential of bioslurry has often been overlooked. A large part of both the scientific and grey literature focuses on the production of energy alone, but does not venture into the multiple uses and intricacies of bioslurry use. Technical organizations such as NGOs, extension services and local universities and, last but not least, smallholders themselves, are often not fully aware of the multiple benefits of bioslurry use, nor do they know of the risks associated with handling and applying it on their farm.This review therefore attempts to synthesize the findings of the growing peer-reviewed literature on bioslurry to provide a sound and scientific basis for bioslurry use. At the same time, it sets out to identify the various research gaps related to bioslurry. [more]
No 54 - The BEFS Analysis for Tanzania : sunflower biodiesel, water, and household food security 12 September 2013 There has been substantial debate regarding the potential of bioenergy as an alternative to fossil fuels, and the potential positive and negative impacts on rural development, food security, and the environment. Growing demand for food, population pressure on land use, and the growing impacts of climate change will create additional challenges for land and resource management. The focus then should be on how bioenergy can be produced in combination with food and other products to enhance both food and energy security. In this context, FAO, with generous funding from the German Federal Ministry of Food, Agriculture and Consumer Protection (BMELV) established the Bioenergy and Food Security (BEFS) Approach, to contribute analytical and policy guidance on how the development of a bioenergy sector could drive agriculture growth and poverty reduction, while fostering food security. The multidisciplinary, cross-ministerial discussion prompted by BEFS is based on information derived from technical analyses with the goal of assisting countries in deciding the direction for policy and development priorities. The analysis included here in builds on the analysis published as a result of the first BEFS Tanzania project and specifically includes three components – 1) Production cost analysis of biodiesel from sunflower; 2) Water availability and management issues in the Wami River Basin; and 3) Household level food security using a country representative dataset. The results of the analysis highlight key areas where the government of Tanzania could integrate energy and agriculture goals to enhance energy and food security jointly. [more]
No 53 - Energy-Smart Food at FAO: An Overview 14 June 2012 This paper presents FAO’s work on energy in relation to specific components of the agrifood chain. It complements two recent publications, Energy-Smart Food for People and Climate Issues Paper and the policy brief, Making the Case for Energy-Smart Food. These publications presented the findings of a 2011 study commissioned by FAO that examined the linkages between energy and agrifood systems and their implications for food security and climate. The study looked at energy uses along the entire agrifood chain from field to plate and the potential of agrifood systems to produce energy. Findings confirmed that agrifood systems use a large share of the global energy supply, rely heavily on fossil fuels to meet production targets and contribute to greenhouse gas emissions. The study concluded that agrifood systems will have to become ‘energy-smart’ to meet future food and energy challenges, and recommended establishing a major long-term multipartner programme on energy-smart food systems based on three pillars (i) improving energy efficiency in agrifood systems, (ii) increasing the use of renewable energy in these systems and (iii) improving access to modern energy services through integrated food and energy production. In response to these recommendations, FAO has launched the multi-partner Energysmart Food for People and Climate (ESF) Programme. This paper illustrates how FAO’s longstanding work in the area of energy and agrifood systems contributes towards the ESF Programme’s objectives. [more]
