Sustainable development aims at addressing economic, social, and environmental concerns, but the current lack of responsive environmental governance hinders progress. Short-term economic development has led to limited actions, unsustainable resource management, and degraded ecosystems. The UN Sustainable Development Goals (SDGs) may continue to fall short of achieving significant progress without a better understanding of how ecosystems contribute to achieving sustainability for all people. Ecosystem governance is an approach that integrates the social and ecological components for improved sustainability and includes principles such as adaptive ecosystem co-management, subsidiarity, and telecoupling framework, as well as principles of democracy and accountability. We explain the importance of ecosystem governance in achieving the SDGs, and suggest some ways to ensure that ecosystem services are meaningfully considered. This paper reflects on how integration of these approaches into policies can enhance the current agenda of sustainability.
The report examines the issue of the deployability abroad of the German Armed Forces, the Bundeswehr, at present and in terms of future-oriented defence reforms. It notes that the Bundeswehr is growing in terms of GDP spending though not yet in numbers, that there are novel ideas about how to further develop German military doctrine toward its use in international military operations within as well as alongside NATO, and that mechanisms for identifying and closing military capability gaps through procurement are coming into place. At the same time, there are a number of industry-related, legal and political constraints in place, some of which appear poised to continue exert influence over the entire sector for years to come. Absent a very conscious effort on the part of the government and the respective ministries and institutions to alter the status quo, especially in conjunction with aggravated security and defence challenges in Germany's vicinity, it appears unlikely that these modest steps will yield substantive results in the short to mid-term.
The Scandinavian forestry sector is facing a major challenge. After a century of rapid growth - both in forestry and the forest products industry - the sector is approaching a situation where rapid growth will no longer be possible simply because most of the annual forest growth is already being utilized. One may choose to let the forces of the free market shape the transition from rapid growth to moderate growth. Or one may choose to pursue policies that are intended to improve the transition in one way or another. Wood Resource Dynamics (i.e. this volume) describes the historical background for the current situation, both concerning the supply of and demand for wood and concerning existing legislation and management practises. The volume further describes the problems caused by slow growth in the forestry sector, and a discussion of the various policies that can be conceived to soften these problems. A system dynamics simulation model was developed to elucidate the likely future effects of the various policies. The volume proceeds to illustrate how this computer simulation model of the Scandinavian forestry sector can be used in discussions of long term policy for the forestry sector. The general applicability of the simulation model is being demonstrated by adapting the model to the case of Finland. Finally, Wood Resource Dynamics gives a short introduction to the system dynamics method for model building by presenting two applications to concrete, short term problerns in the forestry sector - pulp inventory control and forest stand management.
This study examines what happens when contentious lay citizens harness the technical-ecological repertoire of experts as means of challenging nature conservation policy. The causes, manifestations, and implications of this phenomenon are elucidated through a critical discourse analysis. The case study is based on the wolf reintroduction project in Europe, with particular focus on Sweden, using illegal hunting discussions as a point of entry within the hunting community. It reveals the deployment of three topoi, which are defined as stock arguments situated within a discourse. Analysis shows how while some topoi often incur short-term gains in the debate because of their scientific guise, they are fundamentally relegated as folk science (or barstool biology) by government experts and, in some cases, contribute to the further marginalization of other knowledges. Acquiescence to this discourse is shown to greatly impede the debate. Finally, the study shows how lack of trust in the public dialog, which hunters openly recognize to be colonized by ecological expertise, results in increasingly noncommunicative forms of resistance toward policy.
While authoritarian presidents prevail under heavily president-oriented constitutions throughout the post-Soviet region, democracy along parliamentary lines triumphs in Central Europe. This article discusses the constitutional pattern among the post-communist countries on the basis of two general questions: First, how can we explain why strong presidential constitutions dominate throughout the post-Soviet region whereas constrained presidencies and governments anchored in parliament have become the prevailing option in Central Europe? Second, and interlinked with the first question, why have so many post-communist countries (in the post-Soviet region as well as in Central Europe) chosen neither parliamentarism nor presidentialism, but instead semi-presidential arrangements whereby a directly elected president is provided with considerable powers and coexists with a prime minister? The analysis indicates that both historical-institutional and actor-oriented factors are relevant here. Key factors have been regime transition, pre-communist era constitutions and leaders, as well as short-term economic and political considerations. With differing strengths and in partly different ways, these factors seem to have affected the actors' preferences and final constitutional compromises.
It may be challenging to see how illegal hunting, a crime that ostensibly proceeds as shoot, shovel and shut up in remote rural communities, at all communicates with the regime. Examining the socio-legal interplay between hunters and state regulation, however, clarifies illegal hunting to be part of a politically motivated pattern of dissent that signals hunters' disenfranchisement from the polity. While few contemporary illegal hunters cut conscientious figures like Robin Hood, their violation of illegitimate law may likewise testify to a profound disjuncture between legality and legitimacy. This is the premise taken in the following research. Here it is observed contemporary Swedish hunters experience the deliberative system pertaining to wildlife and wolf conservation to be systematically stacked against them and unable to serve as a site for critical law-making that provides equal uptake of all voices. One manifestation of their growing disenfranchisement is the establishment of a counterpublic mobilised on the basis of shared semantics for the sorts of deliberative deficits they argue befall them in the present. Within the remit of their counterpublic, hunters undertake and justify illegal hunting along with other forms of disengaging dissent like abstentions, non-compliance, boycotts and conscientious refusals with state agencies. The research captures hunters' dissent in Smith's deliberative disobedience, a deliberative and Habermasian grounded reinterpretation of the more familiar classical theory of civil disobedience. On this perspective, illegal hunting signals a deficit in the deliberative system, which hunters both bypass by taking an alternative conduit for contestation, and draw attention to when they undertake dissent. The dissent in this case study is deconstructed in terms of its grammar—as simultaneously engaging and disengaging with the premises of power—and in terms of its communicative content. Set within the field of Environmental Communication, the dissertation is intended as an empirical and theoretical contribution to a discussion on the boundaries of political dialogue in the context of civic disenfranchisement: it asks whether some of hunters' dissent may be parsed as a call for a more inclusive debate, or as dialogic acts in themselves. Finally, it presents ways toward short-term and longer-term reconciliation of hunters with the deliberative system, drawing on the work of contestatory citizen mini-publics from the third wave of deliberative democracy.
Sustainable approaches for waste management and sanitation are key to deal with the environmental and health challenges that growing urbanization is creating around the world. Implementing systems that allow to reuse resources contained in the organic waste streams (OWS) is an approach that can bring many benefits, especially in low-medium income areas as the Latin American and Caribbean region, where excreta, wastewater, and waste are not properly managed. The transformation towards these systems requires not only technological changes, but also changes in the way that urban waste and wastewater are governed. The aim of this study was to assess the capacity of the town of Chía (Colombia) to govern the transition towards resource-oriented sanitation and waste management systems. The Governance Capacity Framework (GCF) was used as a method to evaluate the governance capacity of the town to implement these systems. The assessment revealed that the capacity of Chía to govern the implementation of resource-oriented sanitation and waste management systems was low. Furthermore, governance factors that could be hindering the implementation of these systems were identified. Low level of knowledge of resource recovery from OWS in the public spheres, insufficient collaboration and communication across sectors and institutions that had competences on waste management and sanitation, short-term vision within the local decision-making processes and insufficient incentives to support local entrepreneurship on circular economy. Despite these challenges, analysis also revealed the existence of public-private partnerships and entrepreneurs working in successful initiatives linked with resource-oriented systems in Chía and other towns of Cundinamarca county. The study concluded that in Chía there was a gap between local initiatives of resource recovery from OWS that brought environmental, economic, and social benefits at small scale and its inclusion in the local and regional governance systems. Findings of this study touches upon many governance aspects such as knowledge, legislation, financing and even culture. Further research is needed to look closer to each of those and make concrete, feasible and effective proposals that bring change with a long-term sustainability vision. Finally, when analysing the results of the evaluation and making future proposals, strengths, and shortcomings of applying the GCF as an analytical tool for a specific case study like Chía need to be considered.
"The core of the book is a complete annotated translation of the collected 'religious poetry' (Tibetan: mgur) of the Tibetan yogin Tsangnyön Heruka (gTsang smyon Heruka, 1452–1507). The book also contains a translation of a short 'catalogue' (dkar chag) of Tsangnyön's poetry/songs. These two texts were compiled and printed in 1508 by a group of disciples who wanted to express their devotion to their recently deceased master, and make his insights available for others. The Songs of Tsangnyön Heruka begins with an extensive scholarly introduction to Tsangnyön and his songs, providing the reader with a context to the translations. Following the two translated texts, is an appendix introducing Tibetan Buddhism to the general reader, then comes a glossary explaining some of the key terms used in the songs, and finally some back matters, i.e. end notes and bibliographies. Nowadays, Tsangnyön Heruka is mainly known for having written and printed the 'life story' (rnam thar) and 'song collection' (mgur 'bum) of the famous poet-saint Milarepa (1040–1123). However, Tsangnyön is not only one of Tibet's foremost authors and poets, he is also one of the best known 'holy madmen' (smyon pa) of Tibet. These colourful figures challenged powerful leaders and monks with their peculiar and seemingly crazy ways. In sharp contrast to Milarepa's life story and songs, Tsangnyön's were gradually forgotten. Tsangnyön's songs provide us with a fascinating and direct insight into the lifestyle, teachings, and message of the wandering yogins. Moreover, they give us an idea of how it was in Tibet before the Fifth Dalai Lama came to power in the mid-17th century. However, the songs have a direct, down-to-earth, and human message, making them timeless and relevant also for people living in another time and culture.
These songs have never been translated to any language, and they have never been studied thoroughly before."
Stratagems adopted by democratic leaders to try to insinuate, or anchor, a preferred course of action into the larger collective will have a variety of repercussions. Beyond the apparent success of the venture itself, the long-term integrity of the democratic fabric may be at stake if simmering rancour and discontent is left unheeded. These questions would seem particularly pertinent when studying the national side of the evolution of the European Union. The periodic shunting of competencies to European institutions is highly complex, so much so that popular legitimacy for the momentous changes is in effect something of an ephemeral commodity. The referendum, with its unique potential to determine the prevailing vox populi, has from time to time been employed to offset these problems, and lend continued credence to the relinquishment of sovereign power. The political entities that will be the powerhouses in this contest for the hearts and minds of the public are, inevitably, national political parties. They, too, are likely to pay whatever political price will be exacted as a consequence of this unusual form of battle – including the exposition and potential widening of internal rifts. Noticing a dearth of investigative tools that can help us unravel these processes, the author develops a structured framework of analysis specifically designed to "parse" strategic or tactical action, with the aim to gauge likely party-democratic fallout. She makes a first-level distinction between "convincing" strategies (basically conceptualised as compatible with deli¬berative-democratic tenets), and "persuading" strategies (closely associated with a subset of negotiation theory principles focusing on strategic action). While both strategies may lead to the desired short-term outcome – where leadership preferences are duly propagated – a convince/persuade analysis is shown to yield improved understanding of the concomitant, longer-term effects. The author studies the Swedish Social Democratic Party's internal handling of the debates leading up to two pivotal referenda – the EU membership referendum of 1994, and the EMU referendum of 2003. Reviewing a wealth of secondary sources and conducting more than 40 interviews with high-level party officials and other centrally positioned actors (representing both sides of the two issue divides), she is provided with a unique material, which is parsed through the framework (which at this point also proves to be a sound analytical instrument). The study is primarily qualitative in nature, but an entire chapter is devoted to a complementing quantitative analysis where an existing Discourse Quality Index (DQI) is used to determine the level of deliberation prevalent in four party congresses (two preceding the EU referendum; two preceding the EMU referendum). One "convince" sub-dimension, respect, proved to be the one most easily affected by external events, not to mention deadline imposed by the referendum. The qualitative analysis revealed a generally higher level of justification (another "convince" sub-dimension) in the EMU case than in the EU case, and the reverse was true for the respect dimension. In both instances, the party leadership acted to pacify [persuade] the debate, notably by prohibiting government ministers from being active in the respective no-campaigns. A preliminary hypothesis that "deliberative space" shrinks as the final deadline looms was in part corroborated, as turned out to be valid for the respect dimension.
The purpose of this study was to develop a compilation of knowledge about the risk factors of stress and fatigue, and their importance for injuries in agriculture as a basis for preventive measures. The knowledge compilation was based on an extensive literature review and partly on analysis of previously conducted interviews with farmers who suffered accidents. In the literature review, both national and international studies were investigated with regard to the mentioned risk factors for injuries. Also examples of preventive measures applied to farmers were obtained. Documentation of projects was also sought through various industry magazines and websites. The Department of AEM possesses extensive data on injuries in agriculture and forestry in 2004 and 2013. From this data, 460 short stories were analyzed of what happened at the time of the injury and the cause of the injury in 2004. From the 2013 study, 242 stories were analyzed regarding the injury, but also about the measures taken by the farmer to prevent injuries. In addition, 75 band-recorded interviews were analyzed with the affected farmers with further information. In particular, the stories that indicated stress and fatigue as a cause of the injury were studied. The studies of occupational injuries in the Swedish agriculture show that injuries have decreased in absolute terms over the past 10 years. Taking into account the reduced labor requirements in agriculture or decrease in the number of farms in the same period, the number of injuries has not decreased. Farmers are exposed to various risks of injuries at work, such as handling animals (e.g. crushed or trampled by the animals), large machinery and vehicles (such as stuck in the machine, tractor injury) and in construction and repair work (e.g. fall from ladder). In addition to these hazardous conditions, the farmer is also exposed to a variety of stressors by e.g. heavy workload, time pressure, mechanical and technical failures, disease attacks, financial worries, dependent on the weather, government regulations, bureaucracy, working alone and family problems. The literature review showed that farmers who experienced a lot of stress were more likely to experience an accident in their work. Many farmers suffer from fatigue, sleep disorders and insomnia that is related to the high workload and stress they are exposed to, which can affect the ability to make decisions for dangerous situations and injuries as a result. Many of the farmers who suffered injuries in agriculture in Sweden also indicated stress, fatigue, sleepiness, carelessness or negligence as cause of the injuries. There are a lot of fact sheets and brochures with advice to farmers on how to deal with stress and fatigue by example to take breaks, exercise regularly, eat healthy foods and avoid alcohol. Several interventions and programs have been implemented with regard to the prevention of occupational injuries in agriculture. Some studies showed positive results, while most others gave very limited evidence that interventions were effective in reducing agricultural injuries. There is a need for more accurate evaluations of intervention programs for safety in agriculture.
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.
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.
