The global growth in energy demand continues, but the way of meeting rising energy needs is not sustainable. The use of biomass energy is a widely accepted strategy towards sustainable development that sees the fastest rate with the most of increase in power generation followed by strong rises in the consumption of biofuels for transport. Agriculture, forestry and wood energy sector are the leading sources of biomass for bioenergy. However, to be acceptable, biomass feedstock must be produced sustainably. Bioenergy from sustainably managed systems could provide a renewable and carbon neutral source of energy. Bioenergy systems can be relatively complex, intersectoral and site- and scale-specific. The environmental benefits of biomass-for-energy production systems can vary strongly, depending on site properties, climate, management system and input intensities. Bioenergy supply is closely linked to issues of water and land use. It is important to understand the effects of introducing it as well as it is necessary to promote integrated and synergic policies and approaches in the sectors of forestry, agriculture, energy, industry and environment. Biofuels offer attractive solutions to reducing GHG emissions, addressing energy security concerns and have also other socio-economic advantages. Currently produced biofuels are classified as first-generation. Some first-generation biofuels, such as for example ethanol from corn possibly have a limited role in the future transport fuel mix, other ones such as ethanol from sugarcane or biodiesel made from oils extracted from rerennial crops, as well as non-food and industrial crops requiring minimal input and maintenance and offering several benefits over conventional annual crops for ethanol production are promising. Sugarcane ethanol has greenhouse gas (GHG) emissions avoidance potential; can be produced sustainably; can be cost effective without governments support mechanisms, provide useful and valuable co-products; and, if carefully managed with due regard given to sustainable land use, can support the drive for sustainable development in many developing countries. Sugarcane ethanol - currently the most effective biofuel at displacing GHG emissions - is already mitigating GHGs in Brazil. Jatropha curcas L., a multipurpose, drought resistant, perennial plant has gained lot of importance for the production of biodiesel. However, it is important to point out that nearly all of studies have overstated the impacts of first-generation biofuels on global agricultural and land markets due to the fact that they have ignored the role of biofuel by-products. However, feed by-products of first-generation biofuels, such as dried distillers grains with soluble and oilseed meals are used in the livestock industry as protein and energy sources mitigates the price impacts of biofuel production as well as reduce the demand for cropland and moderate the indirect land use consequences. The production of second generation biofuels is expected to start within a few years. Many of the problems associated with first-generation biofuels can be solved by the production of second generation biofuels manufactured from abundant ligno-cellulosic materials such as cereal straw, sugar cane bagasse, forest residues, wastes and dedicated feedstocks (purpose-grown vegetative grasses, short rotation forests and other energy crops). These feedstocks are not food competitive, do not require additional agricultural land and can be grown on marginal and wasteland. Depending on the feedstock choice and the cultivation technique, second-generation biofuel production has the potential to provide benefits such as consuming waste residues and making use of abandoned land. As much as 97-98% of GHG emissions could be avoided by substituting a fossil fuel with wood fuel. Forest fertilization is an attractive option for increasing energy security and reducing net GHG emission. In addition to carbon dioxide the emissions of methane and nitrous oxides may be important factors in GHG balance of biofuels. Forest management rules, best practices for nitrogen fertilizer use and development of second generation technologies use reduce these emissions. Soils have an important role in the global budget of greenhouse gases. However, the effects of biomass production on soil properties are entirely site and practice-specific and little is known about long-term impact. Soil biological systems are resilient and they do not show any lasting impacts due to intensive site management activities. Land management practices can change dramatically the characteristic and gas exchange of an ecosystem. GHG benefits from biomass feedstock use are in some cases significantly lower if the effects of direct¹ or indirect (ILUC²) land use change are taken into account. LUC and ILUC can impact the GHG emission by affecting carbon balance in soil and thus ecosystem. To understand carbon fluxes in an ecosystem large ecosystem units and time scale are critical. Mitigation measures of the impact of land use change on greenhouse gas emissions include the use of residues as feedstock, cultivation of feedstock on abandoned arable land and use of feedstock by-products as substitutes for primary crops as animal feed. Cropping management is the other key factor in estimating GHG emissions associated with LUC and there is significant opportunity to reduce the potential carbon debt and GHG emissions through improved crop and soil management practices, including crop choice, intensity of inputs, harvesting strategy, and tilling practices. Also a system with whole trees harvesting with nutrient compensation is closely to being greenhouse-gas-neutral. Biochar applied to the soil offers a direct method for sequestrating C and generating bioenergy. However, the most recent studies showing that emissions resulting from ILUC are significant have not been systematically compared and summarized and current practices for estimating the effects of ILUC suffer from large uncertainties. Therefore, it seems to be delicate to include the ILUC effects in the GHG emission balance at a country level. The land availability is an important factor in determining bioenergy sustainability. However, even though food and biofuel/biomass can compete for land, this is not inevitably the case. The pattern of completion competition will e.g. depend on whether food security policies are in place. Moreover, the great potential for uncomplicated biomass production lies in using residues and organic waste, introduction of second generation biofuels which are more efficient in use of land and bioresources as well as restoration of degraded and wasted areas. Agroforestry has high potential for simultaneously satisfying many important objectives at ecosystems, economic and social levels. For example, as a very flexible, but low-input system, alley cropping can supply biomass resources in a sustainable way and at the same time provide ecological benefits in Central Europe. A farming system that integrates woody crops with conventional agricultural crops/pasture can more fully utilize the basic resources of water, carbon dioxide, nutrients, and sunlight, thereby producing greater total biomass yield. Overall, whether food prices will rise in parallel to an increase in biofuel demand will depend, more on trade barriers, subsidies, policies and limitations of marketing infrastructure than on lack of physical capacity. There are plant species that provide not only biofuel resources but also has the potential to sequestrate carbon to soil. For example, reed canary grass (RCG, Phalaris arundinacea L.) indicates the potential as a carbon sink. Harvest residues are increasingly utilized to produce energy. Sweden developed a series of recommendations and good-practice guidelines (GPG) for whole tree harvesting practices. Water has a multifarious relationship to energy. Biofuel production will have a relatively minor impact on the global water use. It is critically important to use low-quality water sources and to select the crops and countries that (under current production circumstances) produce bioenergy feedstock in the water-efficient way. However, local and regional impacts of biofuel production could be substantial. Knowledge of watershed characteristics, local hydrology and natural peak flow patterns coupled with site planning, location choice and species choice, are all factors that will determine whether or not this relationship is sustainable. For example, bioethanol's water requirements can range from 5 to 2138 L per liter of ethanol depending on regional irrigation practices. Moreover, sugarcane in Brazil evaporates 2,200 liters for every liter of ethanol, but this demand is met by abundant rainfall. Biomass production can have both positive and negative effects on species diversity. However, woodfuel production systems as well as agroforestry have the potential to increase biodiversity. A regional energy planning could have an important role to play in order to achieve energy-efficient and cost-efficient energy systems. Closing the loop through the optimization of all resources is essential to minimize conflicts in resource requirements as a result of increased biomass feedstock production. A systems approach where the agricultural, forestry, energy, and environmental sectors are considered as components of a single system, and environmental liabilities are used as recoverable resources for biomass feedstock production has the potential to significantly improve the economic, social, and environmental sustainability of biofuels. The LCA (life cycle analysis) approach takes into account all the input and output flows occurring in biomass production systems. The source of biomass has a big impact on LCA outcomes and there is a broad agreement in the scientific community that LCA is one of the best methodologies for the GHG balance calculation of biomass systems. Overall, maximizing benefits of bioenergy while minimizing negative impacts is most likely to occur in the presence of adequate knowledge and frameworks, such as for example certification systems, policy and guidelines. Criteria for achieving sustainability and best land use practices when producing biomass for energy must be established and adopted. ___________ ¹ Direct land-use change occurs when feedstock for biofuels purposes (e.g. soybean for biodiesel) displace a prior land-use (e.g. forest), thereby generating possible changes in the carbon stock of that land. ² Indirect land-use change (ILUC) occurs when pressure on agriculture due to the displacement of previous activity or use of the biomass induces land-use changes on other lands.

There is no doubt now that energy is fundamental to our development. Global energy trends such as higher energy demand and prices, big differences across regions, structural changes in an oil and gas industry increasingly dominated by national companies, the prospect of irreversible climate change, as well as demand for energy security all highlight the need for a rapid transition to a low-carbon, efficient and environmentally benign energy system. The search for energy alternatives involving locally available and renewable resources is one of the main concerns of governments, scientists and business people worldwide. As researchers tackle problems according to global trends, an overwhelming body of research focusing on bioenergy in relation to other types of renewable energy might illustrate the role bioenergy has as the most important renewable energy source for the near and medium-term future. Thus, analyzing the amount of existing research, we found that about 50% (4,911 records) of 9,724 renewable energy records available were bioenergy records. We also found that publications on each of the four main sources of biomass (agriculture, forest, waste and other) represent about one quarter of the 4,911 bioenergy records retrieved. Biomass – the fourth largest energy source after coal, oil and natural gas - is the largest and most important renewable energy option at present and can be used to produce different forms of energy. As a result, it is, together with the other renewable energy options, capable of providing all the energy services required in a modern society, both locally and in most parts of the world. Renewability and versatility are, among many other aspects, important advantages of biomass as an energy source. Moreover, compared to other renewables, biomass resources are common and widespread across the globe. The sustainability potential of global biomass for energy is widely recognized. For example, the annual global primary production of biomass is equivalent to the 4,500 EJ of solar energy captured each year. About 5% of this energy, or 225 EJ, should cover almost 50% of the world's total primary energy demand at present. These 225 EJ are in line with other estimates which assume a sustainable annual bioenergy market of 270 EJ. However, the 50 EJ biomass contributed to global primary energy demand of 470 EJ in 2007, mainly in the form of traditional non-commercial biomass, is only 10% of the global primary energy demand. The potential for energy from biomass depends in part on land availability. Currently, the amount of land devoted to growing energy crops for biomass fuels is only 0.19% of the world's total land area and only 0.5-1.7% of global agricultural land. Although the large potential of algae as a resource of biomass for energy is not taken into consideration in this report, there are results that demonstrate that algae can, in principle, be used as a renewable energy source. From all of these perspectives, the evidence gathered by the report leads to a simple conclusion: Biomass potential for energy production is promising. In most cases, shifting the energy mix from fossil fuels to renewables can now be done using existing technology. Investors in many cases have a reasonably short pay-back because of good availability of lowcost biomass fuels. The latter is of course dependant on local incentives, however. Overall, the future of bioenergy is also to a large extent determined by policy. Thus, an annual bioenergy supply covering global energy demand in 2050, superseding 1,000 EJ, should be possible with sufficient political support. Global production of biomass and biofuel is growing rapidly due to the increasing price of fossil fuels, growing environmental concerns, and considerations regarding the security and diversification of energy supply. There are many scenarios that predict a high potential for biomass in the future. There have also been many studies performed in recent decades to estimate the future demand and supply of bioenergy. Overall, the world's bioenergy potential seems to be large enough to meet the global energy demand in 2050. The current stock of standing forest is a large reservoir of bioenergy and in line with the theoretical potential of biomass energy. However, most of the research studies on biomass potentials ignore existing studies on demand and supply of wood, despite the extensive literature and data on the subject. Taking into account data from a variety of international sources, rough estimates of the energy production potential of woody biomass from forestry show that, in theory, the demand for wood fuel and industrial roundwood in 2050 can be met, without further deforestation, although regional shortages may occur. However, the shift in the energy mix requires much more investment in infrastructure, equipment and in some cases R&D. Moreover, a prerequisite for achieving bioenergy's substantially high potential in all regions is replacing current inefficient and low-intensive management systems with best practices and technologies.

"Scientists, engineers, and a free-choice society is a book about control, largely the governing of children and young people in Sweden and the efforts made to persuade them to choose careers—and identities—in science and technology in the period 1950–2000. It is very much part of an interdisciplinary research tradition in which perspectives taken from the history of science and education are combined with theories from the field of governmentality studies. The book begins by describing a new societal problem that confronted Sweden, like so many other Western countries, in the immediate post-war years, namely a lack of engineers and scientists. The period from the outbreak of the Second World War to the mid fifties saw a new appreciation for scientific research and its application in both the military and civilian sectors. With the reconstruction of Europe and the Marshall Plan at its height in the fifties, technology and science became gradually associated with rising industrial productivity and with economic growth in general.
By the sixties this had left national employment policy with some markedly pronounced objectives. By the end of the decade, it was obvious that the determination to increase student numbers in science and engineering ran contrary to other political ambitions, and did not sit well with the right of the individual to freedom of choice in education. The attempt to respect people's autonomy while at the same time enabling more of them study these particular disciplines shaped a distinct set of strategies that made up the 'positive exercise of power'—what might also be called liberal governing—in which the main idea was to encourage students to come to science and engineering of their own free will.
The book goes on to demonstrate how this strategy of governing through individual autonomy would result in a series of specific measures in the seventies and on, including changes to the curricula and teaching materials, which were matched by activities outside the traditional bounds of learning such as a travelling science shows, advertising campaigns, and the construction of science and technology centres. The book also spells out the sheer reach of this recruitment policy. Many leading figures in Sweden set out to encourage people to become scientists and engineers—these were voices heard not only from government quarters, but also from industry and special interest groups.
Scientists, engineers and a free-choice society does not set out to answer the question of how best to set about attracting young people into science and technology; rather, it is concerned with how that question has been answered by others, and what impact their responses have had on power relations between society and the individual, and indeed on the place of science and engineering
education in the present. - Naturvetarna, ingenjörerna och valfrihetens samhälle handlar om styrning av framförallt barn och ungdomar i Sverige till att välja naturvetenskap och teknik som utbildning, yrke och identitet mellan åren 1950–2000. Ämnesmässigt befinner sig texten i en tvärvetenskaplig forskningstradition där perspektiv från vetenskapshistoria och utbildningshistoria används tillsammans med teoretisk inspiration från fältet governmentality studies. I boken beskrivs inledningsvis framväxten av en ny samhällelig problembild i Sverige och övriga västvärlden under tidig efterkrigstid, nämligen bristen på ingenjörer och naturvetare. Den period som sträckte sig från andra världskriget krigets utbrott till 1950-­?talets mitt hade sett en ny värdering av vetenskaplig forskning och tillämpning, både från de militära och civila delarna av samhället. I samband med återuppbyggnaden av Europa och den pågående Marshallhjälpen sammankopplades teknik och naturvetenskap alltmer med ökad industriell produktivitet men också med ekonomisk tillväxt.
Ovanstående utveckling ledde under 1960-­?talet till att rekryteringspolitiska målsättningar uttalades allt starkare. I slutet av decenniet blev det uppenbart att viljan att höja antalet studerande i teknik och naturvetenskap kom att kollidera med andra utbildningspolitiska ambitioner, framförallt den om individens rätt till ett fritt val av utbildning. I försöken att på samma gång respektera detta självbestämmande och samtidigt skapa fler studerande inom de ovan nämnda disciplinerna växte strategier fram i formen av ett slags "positiv maktutövning" – vad som också kallas liberalt styre – där den bärande idén var att förmå elever att söka sig till naturvetenskap och teknik av sin egen fria vilja.
Boken ger fortsättningsvis prov på hur denna strategi att styra genom individens autonomi frambringade en rad olika specifika påverkanssåtgärder från 1970-­?talet och framåt. Bland dessa återfinns förändrade kursplaner och läromedel, men också insatser utanför den traditionella läromiljön, såsom kringresande vetenskapsshower, reklamkampanjer och uppförandet av teknik-­? och vetenskapscentra. Vad som också framträder i boken är rekryteringspolitikens bredd. Många aktörer i samhället verkade för fler naturvetare och ingenjörer – inte endast på myndighetsnivå utan även inom näringsliv och bland enskilda intresseorganisationer.
Naturvetarna, ingenjörerna och valfrihetens samhälle ger inga svar inte på hur fler ungdomar skall förmås bli intresserade av naturvetenskap och teknik. Snarare handlar boken om hur den frågan besvarats av andra och vilka konsekvenser detta har fått för uppkomsten av nya maktrelationer mellan samhälle och individ, men också för de naturvetenskapliga och tekniska utbildningarnas positioner i samtiden."

The current malnutrition epidemic calls for multiple solutions. The aim of the thesis is to identify the themes of the debate regarding the development of a single Front of-package nutrition label in the European Union. In order to reach the aim, a case study approach was used by looking at the positions of different stakeholders in Sweden, Italy as well as by looking at the debate inside of the European Commission and European Council of Ministries. Data were collected through semi-structured interviews and analysis of documents. The results show that the stakeholders are trying to influence the process towards contrasting outcomes. Different stakeholders argue for very different ideal labelling schemes, while still agreeing on the need for harmonization. Major disagreement arise on whether the label should be voluntary, based on portion or 100 g and on the ideal label design. The type of view depends on the stakeholder role and on its previous experience with this type of labelling. The political debate inside of the European Union is still at an early stage and no consensus has yet been reached, the divergences between the representatives of the Member Countries partially deal with arguments similar to those exposed by the stakeholders. The patterns that emerge from the analysis of the different point of views can facilitate the cooperation between stakeholders and policy-makers. ; Trots teknologisk utveckling har nuvarande livsmedelssystem inte förmått att uppnå livsmedelssäkerhet och folkhälsa för alla. Problemen i världens många livsmedessystem varierar i grad och fokus. I stunden är 17 % av barn som bor i Europa överviktiga, och givet dagens förutsättningar i livsmedelssystem och levnadsvanor förutspås 37 % av vuxna i Europa vara feta 2030. Denna situation är att betrakta som en epidemi, som drabbar vissa grupper i samhället mer än andra, och den är kopplad till många andra icke smittsamma sjukdomar. För individen kan övervikt leda till en lägre livskvalité och för samhället innebär det ökade hälso- och sjukvårdskostnader. Eftersom det är många faktorer som påverkar en individs matvanor ligger ansvaret både på individer och på samhälle för att skapa förutsättningar för en hälsosam livsstil vad gäller livsmedelskonsumtion. För att vägleda konsumenter i matrelaterade val har många länder i Europa en tradition som innebär att konsumenten får hälsorelaterad information om produkten på förpackningen. Det ger konsumenten möjlighet att göra konsumtionsval baserat på mer information. Traditionen inom EU att använda information, fakta och symboler, på livsmedelsprodukter skiljer sig dock mellan länder, och det leder till förvirring och politiska problem. Problemen har banat väg för att EU 2020 kommunicerade målet att skapa en harmoniserad form för information på livsmedelsprodukter som säljs i länder i EU. Detta löfte har skapat debatt och starka röster som ser väldigt olika lösningar på problemet. Syftet med projektet är att identifiera tema i debatten i EU om ett harmoniserat format för information på livsmedelsprodukter. Studien är en fallstudie i vilken debatten från två länders perspektiv, Italien och Sverige, är av speciellt intresse. Tillgängliga sekundärdata från EU och de två valda länderna, och semistrukturerade intervjuer utgör datainsamlingsmetod. En innehållsanalys genomfördes med utgångspunkt i intressent-, varumärkes- och standardutvecklingsbegrepp som hörnstenar för en förståelse för förändringsprocessen. Resultaten från studien visar att representanter för de valda organisationerna i studien förordar en harmonisering av regler för konsumentinformation. Synen på sättet på vilket det skall göras skiljer sig däremot åt. Återkommande tema i intervjuerna är frivillighet, som innebär att det är upp till livsmedelsproducenten att bestämma om produkten skall ha en symbol som visar övergripande näringsinformation eller detaljerad näringsinnehållsinformation. Olika intressenter arbetar på flera fronter för att frågan skall få en lösning. Medan EU samlar in data för att kartlägga alternativa metoder och traditioner arbetar Ministerrådet för att skapa politiska förutsättningar för dialog och samsyn i frågan. Grunden för att skapa ett harmoniserat system ligger i en samsyn på vetenskapliga bevis. Den politiska debatten pågår och kommer att kräva tid innan politiska beslut kan fattas. ; Nonostante il suo sviluppo tecnologico, l'attuale sistema alimentare non è stato in grado di garantire la sicurezza alimentare per tutti. I tipi di malnutrizione presenti variano considerevolmente a livello mondiale; al momento il 17% dei bambini europei è obeso o ovrappeso e, alle presenti condizioni, il 37% degli adulti sarà obeso nel 2030. Questa epidemia di malnutrizione colpisce le categorie svantaggiate in maniera sproporzionata ed è connessa con molte malattie non trasmissibili. La malnutrizione contribuisce a una minore qualità della vita e a una maggior pressione sul sistema sanitario. Ci sono molti fattori che influenzano la dieta delle persone e quindi la responsabilità di risolvere il problema è sia individuale sia collettiva. Negli anni, molti paesi Europei hanno creato sistemi di etichettatura nutrizionale fronte-pacco, con lo scopo di aumentare la comprensione della qualità nutrizionale dei prodotti da parte dei consumatori, così che questi possano fare scelte più consapevoli. In questi sistemi, le informazioni sono presentate sul lato del prodotto che i consumatori vedono al momento dell'acquisto, cosi da facilitarne l'utilizzo. I sistemi di etichettatura fronte-pacco in vigore nell'Unione Europea sono molto diversi tra loro, rappresentando una fonte di confusione per i consumatori e un ostacolo al commercio nel Mercato Unico. Nel 2020, la Commissione Europea ha espresso l'intenzione di adottare una singola etichetta fronte-pacco da utilizzare in tutti i Paesi Membri. L'annuncio ha provocato un grande dibattito, dove gli interessati argomentano soluzioni molto diverse tra loro. Lo scopo della tesi è identificare i temi del dibattito riguardante lo sviluppo di un'unica etichetta fronte-pacco all'interno dell'Unione Europea. Il case-study esplora il dibattito sull'etichetta in corso in Italia e Svezia. I dati sono stati raccolti tramite analisi di documenti e interviste semi-strutturate con stakeholder in entrambi i paesi e con la Commissione Europea. I dati sono quindi stati analizzati con l'aiuto delle teorie sugli stakeholder, sulle etichette, sugli standard e sulle transizioni. I risultati mostrano che, nonostante le organizzazioni selezionate siano in favore dell'armonizzazione, ci sono idee molto diverse rispetto quali caratteristiche l'etichetta comune dovrebbe avere. Temi del dibattito sono, per esempio, la volontarietà dell'etichetta o se questa debba presentare una valutazione complessiva del valore nutrizionale dell'alimento o solo il suo contenuto nutrizionale. Sia il ruolo sia il paese di origine degli intervistati influenzano il loro punto di vista, similarità e differenze di opinione possono essere viste lungo queste linee. Le organizzazioni investigate sono attive sia nel dibattito Europeo sia in quelli nazionali. Le istituzioni europee, responsabili del processo legislativo, sono attive sul tema in modo diverso. La Commissione Europea sta ancora raccogliendo le evidenze scientifiche riguardanti questo tipo di etichette e che serviranno per scrivere la Proposta. Il Consiglio dell'Unione Europea non ha ancora trovato una posizione comune e i Ministri partecipanti hanno posizioni molto differenti. Il dibattito politico interno al Consiglio ha a che fare, per la maggior parte, con i temi presentati dalle organizzazioni intervistate. A causa delle rilevanti differenze in termini di etichetta ideale si può supporre che il dibattito andrà avanti ancora per molto tempo e si evolverà mentre emergono nuove evidenze scientifiche e sono prese decisioni politiche.
