Climate change, environmental degradation, and limited resources are motivations for sustainable forest management. Forests, the most abundant renewable resource on earth, used to make a wide variety of forest-based products for human consumption. To provide a scientific measure of a product’s sustainability and environmental performance, the life cycle assessment (LCA) method is used. This article provides a comprehensive review of environmental performances of forest-based products including traditional building products, emerging (mass-timber) building products and nanomaterials using attributional LCA. Across the supply chain, the product manufacturing life-cycle stage tends to have the largest environmental impacts. However, forest management activities and logistics tend to have the greatest economic impact. In addition, environmental trade-offs exist when regulating emissions as indicated by the latest traditional wood building product LCAs. Interpretation of these LCA results can guide new product development using biomaterials, future (mass) building systems and policy-making on mitigating climate change. Key challenges include handling of uncertainties in the supply chain and complex interactions of environment, material conversion, resource use for product production and quantifying the emissions released.

La production animale est une source essentielle de revenus et d'émissions de gaz à effet de serre (GES) agricoles en Colombie, au Brésil, en Argentine, au Costa Rica, en Uruguay, au Mexique et au Pérou. Plusieurs options de gestion et technologiques, avec un potentiel d'atténuation du méthane entérique, ont été évaluées et leur mise à l'échelle devrait contribuer à la réalisation des objectifs de réduction des émissions de GES. Pourtant, l'adoption généralisée d'options d'atténuation prometteuses reste limitée, ce qui soulève des questions quant à savoir si les objectifs de réduction des émissions envisagés sont réalisables. À l'aide de données générées localement, nous explorons les potentiels d'atténuation des technologies et des pratiques de gestion actuellement proposées pour atténuer les émissions de méthane entérique, pour les systèmes de production bovine dans les pays d'Amérique latine les plus émetteurs. Nous discutons ensuite des obstacles à l'adoption d'innovations qui réduisent considérablement les émissions de méthane entérique d'origine bovine et des changements majeurs dans les politiques et les pratiques qui sont nécessaires pour relever les ambitions nationales dans les pays à forte émission. En utilisant la science la plus récente et la pensée actuelle, nous fournissons notre point de vue sur une approche inclusive et ré-imaginons comment les secteurs universitaire, de la recherche, des affaires et des politiques publiques peuvent soutenir et encourager les changements nécessaires pour élever le niveau d'ambition et atteindre les objectifs de développement durable en envisageant des actions allant de la ferme à l'échelle nationale. La producción ganadera es una fuente fundamental de ingresos y emisiones de gases de efecto invernadero (GEI) agrícolas en Colombia, Brasil, Argentina, Costa Rica, Uruguay, México y Perú. Se han evaluado varias opciones de gestión y tecnológicas, con potencial de mitigación de metano entérico, y se prevé que su escalado contribuya al logro de los objetivos de reducción de emisiones de GEI. Sin embargo, la adopción generalizada de opciones de mitigación prometedoras sigue siendo limitada, lo que plantea dudas sobre si los objetivos de reducción de emisiones previstos son alcanzables. Utilizando datos generados localmente, exploramos los potenciales de mitigación de las tecnologías y prácticas de manejo actualmente propuestas para mitigar las emisiones de metano entérico, para los sistemas de producción ganadera en los países de mayor emisión de América Latina. Luego discutimos las barreras para adoptar innovaciones que reduzcan significativamente las emisiones de metano entérico en el ganado y los cambios importantes en las políticas y prácticas que se necesitan para aumentar las ambiciones nacionales en los países con altas emisiones. Utilizando la ciencia más reciente y el pensamiento actual, brindamos nuestra perspectiva sobre un enfoque inclusivo y reimaginamos cómo los sectores académico, de investigación, empresarial y de políticas públicas pueden apoyar e incentivar los cambios necesarios para elevar el nivel de ambición y alcanzar los objetivos de desarrollo sostenible considerando acciones desde la granja hasta la escala nacional. Livestock production is a pivotal source of income and agricultural greenhouse gas (GHG) emissions in Colombia, Brazil, Argentina, Costa Rica, Uruguay, Mexico and Peru. Several management and technological options, with enteric methane mitigation potential, have been evaluated and their scaling is anticipated to contribute towards achieving GHG emission reduction targets. Yet, widespread adoption of promising mitigation options remains limited, raising questions as to whether envisaged emission reduction targets are achievable. Using locally generated data, we explore the mitigation potentials of technologies and management practices currently proposed to mitigate enteric methane emissions, for cattle production systems in the higher emitting countries of Latin America. We then discuss barriers for adopting innovations that significantly reduce cattle-based enteric methane emissions and the major shifts in policy and practice that are needed to raise national ambitions in the high emitting countries. Using the latest science and current thinking, we provide our perspective on an inclusive approach and re-imagine how the academic, research, business and public policy sectors can support and incentivize the changes needed to raise the level of ambition and achieve sustainable development goals considering actions all the way from the farm to the national scale. الإنتاج الحيواني هو مصدر محوري للدخل وانبعاثات غازات الدفيئة الزراعية في كولومبيا والبرازيل والأرجنتين وكوستاريكا وأوروغواي والمكسيك وبيرو. تم تقييم العديد من خيارات الإدارة والخيارات التكنولوجية، مع إمكانية تخفيف الميثان المعوي، ومن المتوقع أن يساهم قياسها في تحقيق أهداف خفض انبعاثات غازات الدفيئة. ومع ذلك، لا يزال الاعتماد الواسع النطاق لخيارات التخفيف الواعدة محدودًا، مما يثير تساؤلات حول ما إذا كانت أهداف خفض الانبعاثات المتوخاة قابلة للتحقيق. باستخدام البيانات التي تم إنشاؤها محليًا، نستكشف إمكانات التخفيف من التقنيات وممارسات الإدارة المقترحة حاليًا للتخفيف من انبعاثات الميثان المعوية، لأنظمة إنتاج الماشية في البلدان ذات الانبعاثات الأعلى في أمريكا اللاتينية. ثم نناقش العوائق التي تحول دون اعتماد الابتكارات التي تقلل بشكل كبير من انبعاثات الميثان المعوي القائم على الماشية والتحولات الرئيسية في السياسات والممارسات اللازمة لرفع الطموحات الوطنية في البلدان ذات الانبعاثات العالية. باستخدام أحدث العلوم والتفكير الحالي، نقدم وجهة نظرنا حول نهج شامل ونعيد تصور كيف يمكن للقطاعات الأكاديمية والبحثية وقطاع الأعمال والسياسة العامة دعم وتحفيز التغييرات اللازمة لرفع مستوى الطموح وتحقيق أهداف التنمية المستدامة مع الأخذ في الاعتبار الإجراءات على طول الطريق من المزرعة إلى النطاق الوطني.

Reducing methane (CH4) emission from paddy rice production is an important target for many Asian countries in order to comply with their climate policy commitments. National greenhouse gas (GHG) inventory approaches like the Tier-2 approach of the Intergovernmental Panel on Climate Change (IPCC) are useful to assess country-scale emissions from the agricultural sector. In paddy rice, alternate wetting and drying (AWD) is a promising and well-studied water management technique which, as shown in experimental studies, can effectively reduce CH4 emissions. However, so far little is known about GHG emission rates under AWD when the technique is fully controlled by farmers. This study assesses CH4 and nitrous oxide (N2O) fluxes under continuous flooded (CF) and AWD treatments for seven subsequent seasons on farmers’ fields in a pumped irrigation system in Central Luzon, Philippines. Under AWD management, CH4 emissions were substantially reduced (73% in dry season (DS), 21% in wet season (WS)). In all treatments, CH4 is the major contributor to the total GHG emission and is, thus, identified as the driving force to the global warming potential (GWP). The contribution of N2O emissions to the GWP was higher in CF than in AWD, however, these only offset 15% of the decrease in CH4 emission and, therefore, did not jeopardize the strong reduction in the GWP. The study proves the feasibility of AWD under farmers’ management as well as the intended mitigation effect. Resulting from this study, it is recommended to incentivize dissemination strategies in order to improve the effectiveness of mitigation initiatives. A comparison of single CH4 emissions to calculated emissions with the IPCC Tier-2 inventory approach identified that, although averaged values showed a sufficient degree of accuracy, fluctuations for single measurement points have high variation which limit the use of the method for field-level assessments.

Within 20 years, the area of permanent grasslands and pastures in Western Europe has declined by 12%. Semi-natural grasslands are often hot spots of biodiversity and are threatened both by intensive farming and by the abandonment of farmland in marginal areas. In this review, we show that biodiversity, climate change, C sequestration and farming systems issues are highly interconnected in grassland ecosystems. In this context, there are new risks (induced by climate change), new opportunities (linked to carbon sequestration and biodiversity conservation for example) and new challenges (concerning farm management and agricultural practices) for managed grasslands. An assessment of the current research perspectives underlines some key questions: (i) How to reduce the sensitivity and increase the resilience of grassland biodiversity to heat waves and droughts in an altered climate? (ii) How to protect soil organic carbon stocks under global warming? (iii) How to preserve the habitat for rare or endangered species, while managing the functional diversity of the vegetation for agricultural purposes? (iv) How to maintain the heterogeneity and diversity of grassland vegetation at the farm and landscape levels? (v) How to design innovative farming systems that integrate the impacts of farm activity on biodiversity, water and air quality, fossil energy use and greenhouse gas effect? (vi) How to produce integrated knowledge taking account of the consistency of the different management practices and their feasibility at farm level according to four criteria (profitability, labour, agricultural and environmental performance)?

The Upper Yangtze River Basin comprises a densely-populated agricultural region with mountainous and hilly landforms. Intensive cultivation has been extended onto steep hillslopes, which constitute the principal source area for sediment production. Soil conservation on sloping arable lands is thus of utmost priority for persisting sustainable agricultural production and maintaining sound ecosystem services. Although there have been many soil conservation techniques, either promoted by the government or adopted by local farmers, the practiced area was very limited relative to the total area affected by soil erosion. This paper attempts to introduce four popular soil conservation measures on sloping arable lands in this region to enhance a broader scale of implementation, including hedgerow buffers, level trenches, sloping terraces and limited downslope tillage. These practices, although developed from local farmers’ indigenous knowledge for productive purposes, have well conformed to our contemporary understanding of soil erosion processes on sloping landscape affected by human disturbances, were of sound suitability to regional manual tillage agriculture and more trade-off-efficient on rill prevention, runoff harvest and nutrient management.

Giller; Frédéric Baudron; Pytrik Reidsma; João Vasco Silva; João Vasco Silva; Alice G. Laborte; Martin K. van Ittersum;L'intensification durable a été proposée comme moyen d'atteindre la sécurité alimentaire et de réduire les impacts environnementaux de l'agriculture en se concentrant sur la réduction des écarts de rendement sur les terres agricoles existantes tout en améliorant l'efficacité de l'utilisation des ressources. Il existe un consensus général sur le fait que les régions présentant de grands écarts de rendement peuvent bénéficier le plus d'une intensification durable, mais il n'est pas clair dans quelle mesure cela est durable pour les agriculteurs compte tenu de leurs contraintes actuelles en matière de ressources et de leurs stratégies de subsistance. Ici, nous nous appuyons sur trois études de cas contrastées, pour lesquelles des données détaillées au niveau des champs et des exploitations étaient disponibles pour la décomposition des écarts de rendement, afin d'évaluer le fonctionnement de l'intensification durable des cultures (au niveau des champs) au niveau des exploitations à l'aide d'indicateurs environnementaux et socio-économiques. Bien qu'il existe un grand potentiel d'intensification future (plus de production avec plus d'intrants) de la production céréalière dans le sud de l'Éthiopie, l'utilisation actuelle des intrants dans ces systèmes agricoles n'est pas durable sur les plans économique et environnemental au niveau des exploitations. Il en va de même pour la production de riz dans le centre de Luçon, où une intensification durable (plus de production avec moins d'intrants) peut aider à réduire les écarts de rendement et à améliorer l'efficacité de l'utilisation de l'azote (nue), mais elle n'est pas rentable en raison de la forte dépendance à une main-d' œuvre embauchée coûteuse. Des compromis entre la réduction de l'écart de rendement et la productivité du travail ont également été observés dans les systèmes agricoles susmentionnés. Les fermes arables aux Pays-Bas présentent de faibles écarts de rendement ainsi que des performances économiques, des nue et des excédents d'azote plus élevés que ceux observés dans le sud de l'Éthiopie et le centre de Luçon. Pour améliorer la durabilité environnementale, ces exploitations nécessitent des augmentations de l'efficacité de l'utilisation des ressources et une réduction des impacts environnementaux grâce à une utilisation moindre des intrants (même production avec moins d'intrants). Nous concluons que les investissements publics propices à l'innovation et à une agriculture rentable sont essentiels pour rendre les technologies accessibles et abordables pour les agriculteurs et pour veiller à ce que les écarts de rendement puissent être réduits et que les objectifs de durabilité soient atteints au niveau des exploitations. La intensificación sostenible se ha propuesto como una vía para lograr la seguridad alimentaria y reducir los impactos ambientales de la agricultura, centrándose en reducir las brechas de rendimiento en las tierras agrícolas existentes al tiempo que se mejora la eficiencia en el uso de los recursos. Existe un consenso general de que las regiones con grandes brechas de rendimiento pueden beneficiarse más de la intensificación sostenible, pero no está claro qué tan sostenible es esto para los agricultores dadas sus actuales limitaciones de recursos y estrategias de medios de vida. Aquí, nos basamos en tres estudios de casos contrastantes, para los cuales se disponía de datos detallados a nivel de campo y granja para la descomposición de la brecha de rendimiento, para evaluar cómo funciona la intensificación sostenible de los cultivos (a nivel de campo) a nivel de granja utilizando indicadores ambientales y socioeconómicos. Aunque existe un gran potencial para la intensificación futura (más producción con más insumos) de la producción de cereales en el sur de Etiopía, el uso actual de insumos en estos sistemas agrícolas no es económica y ambientalmente sostenible a nivel de granja. Lo mismo ocurre con la producción de arroz en Luzón Central, donde la intensificación sostenible (más producción con menos insumos) puede ayudar a reducir las brechas de rendimiento y mejorar la eficiencia del uso del N (nue), pero no es rentable debido a la gran dependencia de la costosa mano de obra contratada. También se observaron compensaciones entre el cierre de la brecha de rendimiento y la productividad laboral en los sistemas agrícolas mencionados anteriormente. Las granjas cultivables en los Países Bajos exhiben pequeñas brechas de rendimiento, así como un mayor rendimiento económico, superávit de nue y N en comparación con las observadas en el sur de Etiopía y el centro de Luzón. Para mejorar la sostenibilidad ambiental, estas granjas requieren aumentos en la eficiencia del uso de los recursos y una reducción de los impactos ambientales a través de un menor uso de insumos (mismo producto con menos insumos). Concluimos que las inversiones públicas propicias para la innovación y la agricultura rentable son esenciales para que las tecnologías sean accesibles y asequibles para los agricultores y para garantizar que las brechas de rendimiento se puedan reducir y que los objetivos de sostenibilidad se cumplan a nivel de granja. Sustainable intensification has been proposed as a pathway to achieve food security and reduce environmental impacts of agriculture by focusing on narrowing yield gaps on existing agricultural land while improving resource use efficiencies. There is a general consensus that regions with large yield gaps can benefit most from sustainable intensification but it remains unclear how sustainable this is for farmers given their current resource constraints and livelihood strategies. Here, we draw upon three contrasting case studies, for which detailed data at field and farm levels were available for yield gap decomposition, to assess how sustainable intensification of crops (at field level) works out at farm level using environmental and socio-economic indicators. Although there is large potential for future intensification (more output with more input) of cereal production in southern Ethiopia, current input use in these farming systems is not economically and environmentally sustainable at farm level. The same is true for rice production in Central Luzon where sustainable intensification (more output with less input) can help to narrow yield gaps and improve N use efficiency (NUE) but it is not profitable due to the heavy reliance on costly hired labour. Trade-offs between yield gap closure and labour productivity were also observed in the aforementioned farming systems. Arable farms in the Netherlands exhibit small yield gaps as well as higher economic performance, NUE and N surplus compared to those observed in Southern Ethiopia and Central Luzon. For improving environmental sustainability, these farms require increases in resource-use efficiency and a reduction of the environmental impacts through a lower use of inputs (same output with less input). We conclude that public investments conducive for innovation and profitable farming are essential to make technologies accessible and affordable for farmers and to ensure that yield gaps can be narrowed and sustainability objectives served at the farm level. تم اقتراح التكثيف المستدام كمسار لتحقيق الأمن الغذائي والحد من الآثار البيئية للزراعة من خلال التركيز على تضييق فجوات الغلة على الأراضي الزراعية الحالية مع تحسين كفاءة استخدام الموارد. هناك إجماع عام على أن المناطق التي تعاني من فجوات كبيرة في المحاصيل يمكن أن تستفيد أكثر من التكثيف المستدام ولكن لا يزال من غير الواضح مدى استدامة ذلك بالنسبة للمزارعين نظرًا لقيود الموارد الحالية واستراتيجيات سبل العيش. هنا، نعتمد على ثلاث دراسات حالة متناقضة، حيث كانت البيانات التفصيلية على مستوى الحقل والمزرعة متاحة لتحليل فجوة الغلة، لتقييم كيفية عمل التكثيف المستدام للمحاصيل (على مستوى الحقل) على مستوى المزرعة باستخدام المؤشرات البيئية والاجتماعية والاقتصادية. على الرغم من وجود إمكانات كبيرة للتكثيف المستقبلي (المزيد من الإنتاج مع المزيد من المدخلات) لإنتاج الحبوب في جنوب إثيوبيا، فإن الاستخدام الحالي للمدخلات في هذه النظم الزراعية ليس مستدامًا اقتصاديًا وبيئيًا على مستوى المزرعة. وينطبق الشيء نفسه على إنتاج الأرز في وسط لوزون حيث يمكن أن يساعد التكثيف المستدام (المزيد من المخرجات مع مدخلات أقل) في تضييق فجوات الغلة وتحسين كفاءة الاستخدام (NUE) ولكنه ليس مربحًا بسبب الاعتماد الكبير على العمالة المستأجرة المكلفة. كما لوحظت مفاضلات بين إغلاق فجوة العائد وإنتاجية العمل في النظم الزراعية المذكورة أعلاه. تُظهر المزارع الصالحة للزراعة في هولندا فجوات صغيرة في الغلة بالإضافة إلى أداء اقتصادي أعلى وفائض NUE و N مقارنة بتلك التي لوحظت في جنوب إثيوبيا ووسط لوزون. ولتحسين الاستدامة البيئية، تتطلب هذه المزارع زيادات في كفاءة استخدام الموارد وتقليل الآثار البيئية من خلال استخدام أقل للمدخلات (نفس المخرجات مع مدخلات أقل). نستنتج أن الاستثمارات العامة التي تفضي إلى الابتكار والزراعة المربحة ضرورية لجعل التقنيات في متناول المزارعين وبأسعار معقولة ولضمان تضييق فجوات الغلة وتحقيق أهداف الاستدامة على مستوى المزرعة.

Hawkins; Adam M. Komarek; Esther M. Kihoro; Charles F. Nicholson; Amos O. Omore; Gabriel U. Yesuf; Polly J. Ericksen; George C. Schoneveld; Mariana C. Rufino;Tanzania's dairy sector is poorly developed, creating reliance on imports for processed, value-added dairy products and threatening food security, particularly when supply chains are disrupted due to market volatility or armed conflicts. The Tanzanian Dairy Development Roadmap is a domestic development initiative that aims to achieve dairy self-sufficiency by 2030. Here, we model different outcomes of the roadmap, finding that adoption of high-yield cattle breeds is essential for reducing dairy import dependency. Avoided land use change resulting from fewer, higher yielding dairy cattle would lead to lower greenhouse gas emissions. Dairy producers' average incomes could increase despite capital expenditure and land allocation required for the adoption of high-yield breeds. Our findings demonstrate the importance of bottom-up development policies for sustainable food system transformations, which also support food sovereignty, increase incomes for smallholder farmers and contribute towards Tanzania's commitments to reduce greenhouse gas emissions.

Nitrous oxide (N2O) emissions from synthetic and organic N fertilizers are important sources of GHG from sugarcane ethanol. This study aimed to synthesize the literature information and derive regional N2O emissions factors (EFs) for N fertilizers according to Tier 2 approach. This study also evaluated how the use of Tier 2 affects emissions compared with those obtained by the IPCC Tier 1. Moreover, this study examined how N fertilizers can affect GHG emissions and the earning of decarbonization certificates (CBIOs) by ethanol producers. For an ethanol distillery producing 339 million liters annually, the use of Tier 1 and Tier 2 resulted in emissions of 176.5 and 145.2 Gg CO2eq, whereas for the same amount of energy, gasoline would emit 661.8 Gg CO2eq. The addition of nitrification inhibitors (NIs) to N fertilizers and improvements in vinasse/fertilizer management further reduced emissions compared with Tier 2. In Tier 1, the GHG emission savings would result 485,270 CBIOs, worth 4.85 million US$ at US$10 per CBIO. But if the IPCC Tier 2 is considered, the annual CBIOs would be worth 5.17 million US$. Using NIs and improving vinasse/fertilizer management may bring an additional US$ 31,700 and US$ 48,000 revenue above that of Tier 2. Public and sectorial policies behind decarbonization certificates can encourage farmers and decision-makers to pursue more efficient and economical solutions to further decrease GHG emissions and improve the sustainability of ethanol.

Spatially explicit knowledge of aboveground biomass (AGB) in large areas is important for accurate carbon accounting and quantifying the effect of forest disturbance on the terrestrial carbon cycle. We estimated AGB from 1990 to 2011 in northern Guangdong, China, based on a spatially explicit dataset derived from six years of national forest inventory (NFI) plots, Landsat time series imagery (1986–2011) and Advanced Land Observing Satellite (ALOS) Phased Array L-band Synthetic Aperture Radars (PALSAR) 25 m mosaic data (2007–2010). Four types of variables were derived for modeling and assessment. The random forest approach was used to seek the optimal variables for mapping and validation. The root mean square error (RMSE) of plot-level validation was between 6.44 and 39.49 (t/ha), the normalized root-mean-square error (NRMSE) was between 7.49% and 19.01% and mean absolute error (MAE) was between 5.06 and 23.84 t/ha. The highest coefficient of determination R2 of 0.8 and the lowest NRMSE of 7.49% were reported in 2006. A clear increasing trend of mean AGB from the lowest value of 13.58 t/ha to the highest value of 66.25 t/ha was witnessed between 1988 and 2000, while after 2000 there was a fluctuating ascending change, with a peak mean AGB of 67.13 t/ha in 2004. By integrating AGB change with forest disturbance, the trend in disturbance area closely corresponded with the trend in AGB decrease. To determine the driving forces of these changes, the correlation analysis was adopted and exploratory factor analysis (EFA) method was used to find a factor rotation that maximizes this variance and represents the dominant factors of nine climate elements and nine human activities elements affecting the AGB dynamics. Overall, human activities contributed more to short-term AGB dynamics than climate data. Harvesting and human-induced fire in combination with rock desertification and global warming made a strong contribution to AGB changes. This study provides valuable information for the relationships between forest AGB and climate as well as forest disturbance in subtropical zones.

AbstractUnder the US Environmental Protection Agency's Renewable Fuel Standard (RFS) program, mandates to increase the consumption of renewable fuels in transportation in the USA are leading to the emergence of a biofuel economy with infrastructure implications. This shift requires immediate consideration, as current engineering infrastructures may not be sufficient to support the realization of the mandates. New biorefineries will need to be established where suitable land is available and the climate is appropriate for growing feedstocks. Investments may need to be made to accommodate increases in local, regional, and national traffic from the transport of feedstocks and finished biofuels. Further, the large water demands of biorefineries and of growing feedstocks impose even greater pressure on water supply utilities. Higher sediment and nutrient runoffs from more intensive cultivation of corn (as feedstock for ethanol) have negative water quality effects that may lead to the need for upgrading drinking‐water treatment facilities. Any infrastructure expansion should be conducted strategically, keeping in mind resource constraints, and environmental and social impacts. To understand the infrastructure needs and bottlenecks of biofuel development, a systems approach encompassing all aspects of the problem is essential. Research is needed to quantify the interdependencies, resiliency, and sustainability of the entire system in meeting biofuel goals. Research is also needed to integrate the social and physical aspects of the problem into a holistic framework for planning and management purposes. This paper reviews the literature to gain insights into some implications of biofuel development for engineering infrastructures in the USA. © 2011 Society of Chemical Industry and John Wiley & Sons, Ltd

Climate change, environmental degradation, and limited resources are motivations for sustainable forest management. Forests, the most abundant renewable resource on earth, used to make a wide variety of forest-based products for human consumption. To provide a scientific measure of a product’s sustainability and environmental performance, the life cycle assessment (LCA) method is used. This article provides a comprehensive review of environmental performances of forest-based products including traditional building products, emerging (mass-timber) building products and nanomaterials using attributional LCA. Across the supply chain, the product manufacturing life-cycle stage tends to have the largest environmental impacts. However, forest management activities and logistics tend to have the greatest economic impact. In addition, environmental trade-offs exist when regulating emissions as indicated by the latest traditional wood building product LCAs. Interpretation of these LCA results can guide new product development using biomaterials, future (mass) building systems and policy-making on mitigating climate change. Key challenges include handling of uncertainties in the supply chain and complex interactions of environment, material conversion, resource use for product production and quantifying the emissions released.

La production animale est une source essentielle de revenus et d'émissions de gaz à effet de serre (GES) agricoles en Colombie, au Brésil, en Argentine, au Costa Rica, en Uruguay, au Mexique et au Pérou. Plusieurs options de gestion et technologiques, avec un potentiel d'atténuation du méthane entérique, ont été évaluées et leur mise à l'échelle devrait contribuer à la réalisation des objectifs de réduction des émissions de GES. Pourtant, l'adoption généralisée d'options d'atténuation prometteuses reste limitée, ce qui soulève des questions quant à savoir si les objectifs de réduction des émissions envisagés sont réalisables. À l'aide de données générées localement, nous explorons les potentiels d'atténuation des technologies et des pratiques de gestion actuellement proposées pour atténuer les émissions de méthane entérique, pour les systèmes de production bovine dans les pays d'Amérique latine les plus émetteurs. Nous discutons ensuite des obstacles à l'adoption d'innovations qui réduisent considérablement les émissions de méthane entérique d'origine bovine et des changements majeurs dans les politiques et les pratiques qui sont nécessaires pour relever les ambitions nationales dans les pays à forte émission. En utilisant la science la plus récente et la pensée actuelle, nous fournissons notre point de vue sur une approche inclusive et ré-imaginons comment les secteurs universitaire, de la recherche, des affaires et des politiques publiques peuvent soutenir et encourager les changements nécessaires pour élever le niveau d'ambition et atteindre les objectifs de développement durable en envisageant des actions allant de la ferme à l'échelle nationale. La producción ganadera es una fuente fundamental de ingresos y emisiones de gases de efecto invernadero (GEI) agrícolas en Colombia, Brasil, Argentina, Costa Rica, Uruguay, México y Perú. Se han evaluado varias opciones de gestión y tecnológicas, con potencial de mitigación de metano entérico, y se prevé que su escalado contribuya al logro de los objetivos de reducción de emisiones de GEI. Sin embargo, la adopción generalizada de opciones de mitigación prometedoras sigue siendo limitada, lo que plantea dudas sobre si los objetivos de reducción de emisiones previstos son alcanzables. Utilizando datos generados localmente, exploramos los potenciales de mitigación de las tecnologías y prácticas de manejo actualmente propuestas para mitigar las emisiones de metano entérico, para los sistemas de producción ganadera en los países de mayor emisión de América Latina. Luego discutimos las barreras para adoptar innovaciones que reduzcan significativamente las emisiones de metano entérico en el ganado y los cambios importantes en las políticas y prácticas que se necesitan para aumentar las ambiciones nacionales en los países con altas emisiones. Utilizando la ciencia más reciente y el pensamiento actual, brindamos nuestra perspectiva sobre un enfoque inclusivo y reimaginamos cómo los sectores académico, de investigación, empresarial y de políticas públicas pueden apoyar e incentivar los cambios necesarios para elevar el nivel de ambición y alcanzar los objetivos de desarrollo sostenible considerando acciones desde la granja hasta la escala nacional. Livestock production is a pivotal source of income and agricultural greenhouse gas (GHG) emissions in Colombia, Brazil, Argentina, Costa Rica, Uruguay, Mexico and Peru. Several management and technological options, with enteric methane mitigation potential, have been evaluated and their scaling is anticipated to contribute towards achieving GHG emission reduction targets. Yet, widespread adoption of promising mitigation options remains limited, raising questions as to whether envisaged emission reduction targets are achievable. Using locally generated data, we explore the mitigation potentials of technologies and management practices currently proposed to mitigate enteric methane emissions, for cattle production systems in the higher emitting countries of Latin America. We then discuss barriers for adopting innovations that significantly reduce cattle-based enteric methane emissions and the major shifts in policy and practice that are needed to raise national ambitions in the high emitting countries. Using the latest science and current thinking, we provide our perspective on an inclusive approach and re-imagine how the academic, research, business and public policy sectors can support and incentivize the changes needed to raise the level of ambition and achieve sustainable development goals considering actions all the way from the farm to the national scale. الإنتاج الحيواني هو مصدر محوري للدخل وانبعاثات غازات الدفيئة الزراعية في كولومبيا والبرازيل والأرجنتين وكوستاريكا وأوروغواي والمكسيك وبيرو. تم تقييم العديد من خيارات الإدارة والخيارات التكنولوجية، مع إمكانية تخفيف الميثان المعوي، ومن المتوقع أن يساهم قياسها في تحقيق أهداف خفض انبعاثات غازات الدفيئة. ومع ذلك، لا يزال الاعتماد الواسع النطاق لخيارات التخفيف الواعدة محدودًا، مما يثير تساؤلات حول ما إذا كانت أهداف خفض الانبعاثات المتوخاة قابلة للتحقيق. باستخدام البيانات التي تم إنشاؤها محليًا، نستكشف إمكانات التخفيف من التقنيات وممارسات الإدارة المقترحة حاليًا للتخفيف من انبعاثات الميثان المعوية، لأنظمة إنتاج الماشية في البلدان ذات الانبعاثات الأعلى في أمريكا اللاتينية. ثم نناقش العوائق التي تحول دون اعتماد الابتكارات التي تقلل بشكل كبير من انبعاثات الميثان المعوي القائم على الماشية والتحولات الرئيسية في السياسات والممارسات اللازمة لرفع الطموحات الوطنية في البلدان ذات الانبعاثات العالية. باستخدام أحدث العلوم والتفكير الحالي، نقدم وجهة نظرنا حول نهج شامل ونعيد تصور كيف يمكن للقطاعات الأكاديمية والبحثية وقطاع الأعمال والسياسة العامة دعم وتحفيز التغييرات اللازمة لرفع مستوى الطموح وتحقيق أهداف التنمية المستدامة مع الأخذ في الاعتبار الإجراءات على طول الطريق من المزرعة إلى النطاق الوطني.

Reducing methane (CH4) emission from paddy rice production is an important target for many Asian countries in order to comply with their climate policy commitments. National greenhouse gas (GHG) inventory approaches like the Tier-2 approach of the Intergovernmental Panel on Climate Change (IPCC) are useful to assess country-scale emissions from the agricultural sector. In paddy rice, alternate wetting and drying (AWD) is a promising and well-studied water management technique which, as shown in experimental studies, can effectively reduce CH4 emissions. However, so far little is known about GHG emission rates under AWD when the technique is fully controlled by farmers. This study assesses CH4 and nitrous oxide (N2O) fluxes under continuous flooded (CF) and AWD treatments for seven subsequent seasons on farmers’ fields in a pumped irrigation system in Central Luzon, Philippines. Under AWD management, CH4 emissions were substantially reduced (73% in dry season (DS), 21% in wet season (WS)). In all treatments, CH4 is the major contributor to the total GHG emission and is, thus, identified as the driving force to the global warming potential (GWP). The contribution of N2O emissions to the GWP was higher in CF than in AWD, however, these only offset 15% of the decrease in CH4 emission and, therefore, did not jeopardize the strong reduction in the GWP. The study proves the feasibility of AWD under farmers’ management as well as the intended mitigation effect. Resulting from this study, it is recommended to incentivize dissemination strategies in order to improve the effectiveness of mitigation initiatives. A comparison of single CH4 emissions to calculated emissions with the IPCC Tier-2 inventory approach identified that, although averaged values showed a sufficient degree of accuracy, fluctuations for single measurement points have high variation which limit the use of the method for field-level assessments.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Journal 2007Publisher:CABI Publishing Authors: Soussana, Jean-François,; Duru, Michel,;Abstract In Europe, grassland is one of the dominant forms of land use. Within 20 years, the area of permanent grasslands and pastures in Western Europe has declined by 12%. Semi-natural grasslands are often hot spots of biodiversity and are threatened both by intensive farming and by the abandonment of farmland in marginal areas. In this review, we show that biodiversity, climate change, C sequestration and farming systems issues are highly interconnected in grassland ecosystems. In this context, there are new risks (induced by climate change), new opportunities (linked to carbon sequestration and biodiversity conservation for example) and new challenges (concerning farm management and agricultural practices) for managed grasslands. An assessment of the current research perspectives underlines some key questions: (i) How to reduce the sensitivity and increase the resilience of grassland biodiversity to heat waves and droughts in an altered climate? (ii) How to protect soil organic carbon stocks under global warming? (iii) How to preserve the habitat for rare or endangered species, while managing the functional diversity of the vegetation for agricultural purposes? (iv) How to maintain the heterogeneity and diversity of grassland vegetation at the farm and landscape levels? (v) How to design innovative farming systems that integrate the impacts of farm activity on biodiversity, water and air quality, fossil energy use and greenhouse gas effect? (vi) How to produce integrated knowledge taking account of the consistency of the different management practices and their feasibility at farm level according to four criteria (profitability, labour, agricultural and environmental performance)?

The Upper Yangtze River Basin comprises a densely-populated agricultural region with mountainous and hilly landforms. Intensive cultivation has been extended onto steep hillslopes, which constitute the principal source area for sediment production. Soil conservation on sloping arable lands is thus of utmost priority for persisting sustainable agricultural production and maintaining sound ecosystem services. Although there have been many soil conservation techniques, either promoted by the government or adopted by local farmers, the practiced area was very limited relative to the total area affected by soil erosion. This paper attempts to introduce four popular soil conservation measures on sloping arable lands in this region to enhance a broader scale of implementation, including hedgerow buffers, level trenches, sloping terraces and limited downslope tillage. These practices, although developed from local farmers’ indigenous knowledge for productive purposes, have well conformed to our contemporary understanding of soil erosion processes on sloping landscape affected by human disturbances, were of sound suitability to regional manual tillage agriculture and more trade-off-efficient on rill prevention, runoff harvest and nutrient management.

Giller; Frédéric Baudron; Pytrik Reidsma; João Vasco Silva; João Vasco Silva; Alice G. Laborte; Martin K. van Ittersum;L'intensification durable a été proposée comme moyen d'atteindre la sécurité alimentaire et de réduire les impacts environnementaux de l'agriculture en se concentrant sur la réduction des écarts de rendement sur les terres agricoles existantes tout en améliorant l'efficacité de l'utilisation des ressources. Il existe un consensus général sur le fait que les régions présentant de grands écarts de rendement peuvent bénéficier le plus d'une intensification durable, mais il n'est pas clair dans quelle mesure cela est durable pour les agriculteurs compte tenu de leurs contraintes actuelles en matière de ressources et de leurs stratégies de subsistance. Ici, nous nous appuyons sur trois études de cas contrastées, pour lesquelles des données détaillées au niveau des champs et des exploitations étaient disponibles pour la décomposition des écarts de rendement, afin d'évaluer le fonctionnement de l'intensification durable des cultures (au niveau des champs) au niveau des exploitations à l'aide d'indicateurs environnementaux et socio-économiques. Bien qu'il existe un grand potentiel d'intensification future (plus de production avec plus d'intrants) de la production céréalière dans le sud de l'Éthiopie, l'utilisation actuelle des intrants dans ces systèmes agricoles n'est pas durable sur les plans économique et environnemental au niveau des exploitations. Il en va de même pour la production de riz dans le centre de Luçon, où une intensification durable (plus de production avec moins d'intrants) peut aider à réduire les écarts de rendement et à améliorer l'efficacité de l'utilisation de l'azote (nue), mais elle n'est pas rentable en raison de la forte dépendance à une main-d' œuvre embauchée coûteuse. Des compromis entre la réduction de l'écart de rendement et la productivité du travail ont également été observés dans les systèmes agricoles susmentionnés. Les fermes arables aux Pays-Bas présentent de faibles écarts de rendement ainsi que des performances économiques, des nue et des excédents d'azote plus élevés que ceux observés dans le sud de l'Éthiopie et le centre de Luçon. Pour améliorer la durabilité environnementale, ces exploitations nécessitent des augmentations de l'efficacité de l'utilisation des ressources et une réduction des impacts environnementaux grâce à une utilisation moindre des intrants (même production avec moins d'intrants). Nous concluons que les investissements publics propices à l'innovation et à une agriculture rentable sont essentiels pour rendre les technologies accessibles et abordables pour les agriculteurs et pour veiller à ce que les écarts de rendement puissent être réduits et que les objectifs de durabilité soient atteints au niveau des exploitations. La intensificación sostenible se ha propuesto como una vía para lograr la seguridad alimentaria y reducir los impactos ambientales de la agricultura, centrándose en reducir las brechas de rendimiento en las tierras agrícolas existentes al tiempo que se mejora la eficiencia en el uso de los recursos. Existe un consenso general de que las regiones con grandes brechas de rendimiento pueden beneficiarse más de la intensificación sostenible, pero no está claro qué tan sostenible es esto para los agricultores dadas sus actuales limitaciones de recursos y estrategias de medios de vida. Aquí, nos basamos en tres estudios de casos contrastantes, para los cuales se disponía de datos detallados a nivel de campo y granja para la descomposición de la brecha de rendimiento, para evaluar cómo funciona la intensificación sostenible de los cultivos (a nivel de campo) a nivel de granja utilizando indicadores ambientales y socioeconómicos. Aunque existe un gran potencial para la intensificación futura (más producción con más insumos) de la producción de cereales en el sur de Etiopía, el uso actual de insumos en estos sistemas agrícolas no es económica y ambientalmente sostenible a nivel de granja. Lo mismo ocurre con la producción de arroz en Luzón Central, donde la intensificación sostenible (más producción con menos insumos) puede ayudar a reducir las brechas de rendimiento y mejorar la eficiencia del uso del N (nue), pero no es rentable debido a la gran dependencia de la costosa mano de obra contratada. También se observaron compensaciones entre el cierre de la brecha de rendimiento y la productividad laboral en los sistemas agrícolas mencionados anteriormente. Las granjas cultivables en los Países Bajos exhiben pequeñas brechas de rendimiento, así como un mayor rendimiento económico, superávit de nue y N en comparación con las observadas en el sur de Etiopía y el centro de Luzón. Para mejorar la sostenibilidad ambiental, estas granjas requieren aumentos en la eficiencia del uso de los recursos y una reducción de los impactos ambientales a través de un menor uso de insumos (mismo producto con menos insumos). Concluimos que las inversiones públicas propicias para la innovación y la agricultura rentable son esenciales para que las tecnologías sean accesibles y asequibles para los agricultores y para garantizar que las brechas de rendimiento se puedan reducir y que los objetivos de sostenibilidad se cumplan a nivel de granja. Sustainable intensification has been proposed as a pathway to achieve food security and reduce environmental impacts of agriculture by focusing on narrowing yield gaps on existing agricultural land while improving resource use efficiencies. There is a general consensus that regions with large yield gaps can benefit most from sustainable intensification but it remains unclear how sustainable this is for farmers given their current resource constraints and livelihood strategies. Here, we draw upon three contrasting case studies, for which detailed data at field and farm levels were available for yield gap decomposition, to assess how sustainable intensification of crops (at field level) works out at farm level using environmental and socio-economic indicators. Although there is large potential for future intensification (more output with more input) of cereal production in southern Ethiopia, current input use in these farming systems is not economically and environmentally sustainable at farm level. The same is true for rice production in Central Luzon where sustainable intensification (more output with less input) can help to narrow yield gaps and improve N use efficiency (NUE) but it is not profitable due to the heavy reliance on costly hired labour. Trade-offs between yield gap closure and labour productivity were also observed in the aforementioned farming systems. Arable farms in the Netherlands exhibit small yield gaps as well as higher economic performance, NUE and N surplus compared to those observed in Southern Ethiopia and Central Luzon. For improving environmental sustainability, these farms require increases in resource-use efficiency and a reduction of the environmental impacts through a lower use of inputs (same output with less input). We conclude that public investments conducive for innovation and profitable farming are essential to make technologies accessible and affordable for farmers and to ensure that yield gaps can be narrowed and sustainability objectives served at the farm level. تم اقتراح التكثيف المستدام كمسار لتحقيق الأمن الغذائي والحد من الآثار البيئية للزراعة من خلال التركيز على تضييق فجوات الغلة على الأراضي الزراعية الحالية مع تحسين كفاءة استخدام الموارد. هناك إجماع عام على أن المناطق التي تعاني من فجوات كبيرة في المحاصيل يمكن أن تستفيد أكثر من التكثيف المستدام ولكن لا يزال من غير الواضح مدى استدامة ذلك بالنسبة للمزارعين نظرًا لقيود الموارد الحالية واستراتيجيات سبل العيش. هنا، نعتمد على ثلاث دراسات حالة متناقضة، حيث كانت البيانات التفصيلية على مستوى الحقل والمزرعة متاحة لتحليل فجوة الغلة، لتقييم كيفية عمل التكثيف المستدام للمحاصيل (على مستوى الحقل) على مستوى المزرعة باستخدام المؤشرات البيئية والاجتماعية والاقتصادية. على الرغم من وجود إمكانات كبيرة للتكثيف المستقبلي (المزيد من الإنتاج مع المزيد من المدخلات) لإنتاج الحبوب في جنوب إثيوبيا، فإن الاستخدام الحالي للمدخلات في هذه النظم الزراعية ليس مستدامًا اقتصاديًا وبيئيًا على مستوى المزرعة. وينطبق الشيء نفسه على إنتاج الأرز في وسط لوزون حيث يمكن أن يساعد التكثيف المستدام (المزيد من المخرجات مع مدخلات أقل) في تضييق فجوات الغلة وتحسين كفاءة الاستخدام (NUE) ولكنه ليس مربحًا بسبب الاعتماد الكبير على العمالة المستأجرة المكلفة. كما لوحظت مفاضلات بين إغلاق فجوة العائد وإنتاجية العمل في النظم الزراعية المذكورة أعلاه. تُظهر المزارع الصالحة للزراعة في هولندا فجوات صغيرة في الغلة بالإضافة إلى أداء اقتصادي أعلى وفائض NUE و N مقارنة بتلك التي لوحظت في جنوب إثيوبيا ووسط لوزون. ولتحسين الاستدامة البيئية، تتطلب هذه المزارع زيادات في كفاءة استخدام الموارد وتقليل الآثار البيئية من خلال استخدام أقل للمدخلات (نفس المخرجات مع مدخلات أقل). نستنتج أن الاستثمارات العامة التي تفضي إلى الابتكار والزراعة المربحة ضرورية لجعل التقنيات في متناول المزارعين وبأسعار معقولة ولضمان تضييق فجوات الغلة وتحقيق أهداف الاستدامة على مستوى المزرعة.

Hawkins; Adam M. Komarek; Esther M. Kihoro; Charles F. Nicholson; Amos O. Omore; Gabriel U. Yesuf; Polly J. Ericksen; George C. Schoneveld; Mariana C. Rufino;Tanzania's dairy sector is poorly developed, creating reliance on imports for processed, value-added dairy products and threatening food security, particularly when supply chains are disrupted due to market volatility or armed conflicts. The Tanzanian Dairy Development Roadmap is a domestic development initiative that aims to achieve dairy self-sufficiency by 2030. Here, we model different outcomes of the roadmap, finding that adoption of high-yield cattle breeds is essential for reducing dairy import dependency. Avoided land use change resulting from fewer, higher yielding dairy cattle would lead to lower greenhouse gas emissions. Dairy producers' average incomes could increase despite capital expenditure and land allocation required for the adoption of high-yield breeds. Our findings demonstrate the importance of bottom-up development policies for sustainable food system transformations, which also support food sovereignty, increase incomes for smallholder farmers and contribute towards Tanzania's commitments to reduce greenhouse gas emissions.

Nitrous oxide (N2O) emissions from synthetic and organic N fertilizers are important sources of GHG from sugarcane ethanol. This study aimed to synthesize the literature information and derive regional N2O emissions factors (EFs) for N fertilizers according to Tier 2 approach. This study also evaluated how the use of Tier 2 affects emissions compared with those obtained by the IPCC Tier 1. Moreover, this study examined how N fertilizers can affect GHG emissions and the earning of decarbonization certificates (CBIOs) by ethanol producers. For an ethanol distillery producing 339 million liters annually, the use of Tier 1 and Tier 2 resulted in emissions of 176.5 and 145.2 Gg CO2eq, whereas for the same amount of energy, gasoline would emit 661.8 Gg CO2eq. The addition of nitrification inhibitors (NIs) to N fertilizers and improvements in vinasse/fertilizer management further reduced emissions compared with Tier 2. In Tier 1, the GHG emission savings would result 485,270 CBIOs, worth 4.85 million US$ at US$10 per CBIO. But if the IPCC Tier 2 is considered, the annual CBIOs would be worth 5.17 million US$. Using NIs and improving vinasse/fertilizer management may bring an additional US$ 31,700 and US$ 48,000 revenue above that of Tier 2. Public and sectorial policies behind decarbonization certificates can encourage farmers and decision-makers to pursue more efficient and economical solutions to further decrease GHG emissions and improve the sustainability of ethanol.

Spatially explicit knowledge of aboveground biomass (AGB) in large areas is important for accurate carbon accounting and quantifying the effect of forest disturbance on the terrestrial carbon cycle. We estimated AGB from 1990 to 2011 in northern Guangdong, China, based on a spatially explicit dataset derived from six years of national forest inventory (NFI) plots, Landsat time series imagery (1986–2011) and Advanced Land Observing Satellite (ALOS) Phased Array L-band Synthetic Aperture Radars (PALSAR) 25 m mosaic data (2007–2010). Four types of variables were derived for modeling and assessment. The random forest approach was used to seek the optimal variables for mapping and validation. The root mean square error (RMSE) of plot-level validation was between 6.44 and 39.49 (t/ha), the normalized root-mean-square error (NRMSE) was between 7.49% and 19.01% and mean absolute error (MAE) was between 5.06 and 23.84 t/ha. The highest coefficient of determination R2 of 0.8 and the lowest NRMSE of 7.49% were reported in 2006. A clear increasing trend of mean AGB from the lowest value of 13.58 t/ha to the highest value of 66.25 t/ha was witnessed between 1988 and 2000, while after 2000 there was a fluctuating ascending change, with a peak mean AGB of 67.13 t/ha in 2004. By integrating AGB change with forest disturbance, the trend in disturbance area closely corresponded with the trend in AGB decrease. To determine the driving forces of these changes, the correlation analysis was adopted and exploratory factor analysis (EFA) method was used to find a factor rotation that maximizes this variance and represents the dominant factors of nine climate elements and nine human activities elements affecting the AGB dynamics. Overall, human activities contributed more to short-term AGB dynamics than climate data. Harvesting and human-induced fire in combination with rock desertification and global warming made a strong contribution to AGB changes. This study provides valuable information for the relationships between forest AGB and climate as well as forest disturbance in subtropical zones.

AbstractUnder the US Environmental Protection Agency's Renewable Fuel Standard (RFS) program, mandates to increase the consumption of renewable fuels in transportation in the USA are leading to the emergence of a biofuel economy with infrastructure implications. This shift requires immediate consideration, as current engineering infrastructures may not be sufficient to support the realization of the mandates. New biorefineries will need to be established where suitable land is available and the climate is appropriate for growing feedstocks. Investments may need to be made to accommodate increases in local, regional, and national traffic from the transport of feedstocks and finished biofuels. Further, the large water demands of biorefineries and of growing feedstocks impose even greater pressure on water supply utilities. Higher sediment and nutrient runoffs from more intensive cultivation of corn (as feedstock for ethanol) have negative water quality effects that may lead to the need for upgrading drinking‐water treatment facilities. Any infrastructure expansion should be conducted strategically, keeping in mind resource constraints, and environmental and social impacts. To understand the infrastructure needs and bottlenecks of biofuel development, a systems approach encompassing all aspects of the problem is essential. Research is needed to quantify the interdependencies, resiliency, and sustainability of the entire system in meeting biofuel goals. Research is also needed to integrate the social and physical aspects of the problem into a holistic framework for planning and management purposes. This paper reviews the literature to gain insights into some implications of biofuel development for engineering infrastructures in the USA. © 2011 Society of Chemical Industry and John Wiley & Sons, Ltd
