Dynamics of societal material stocks such as buildings and infrastructures and their spatial patterns drive surging resource use and emissions. Building up and maintaining stocks requires large amounts of resources; currently stock-building materials amount to almost 60% of all materials used by humanity. Buildings, infrastructures and machinery shape social practices of production and consumption, thereby creating path dependencies for future resource use. They constitute the physical basis of the spatial organization of most socio-economic activities, for example as mobility networks, urbanization and settlement patterns and various other infrastructures. This dataset features a detailed map of material stocks for the whole of Germany on a 10m grid based on high resolution Earth Observation data (Sentinel-1 + Sentinel-2), crowd-sourced geodata (OSM) and material intensity factors. Temporal extent The map is representative for ca. 2018. Data format Per federal state, the data come in tiles of 30x30km (see shapefile). The projection is EPSG:3035. The images are compressed GeoTiff files (*.tif). There is a mosaic in GDAL Virtual format (*.vrt), which can readily be opened in most Geographic Information Systems. The dataset features area and mass for different street types area and mass for different rail types area and mass for other infrastructure area, volume and mass for different building types Masses are reported as total values, and per material category. Units area in m² height in m volume in m³ mass in t for infrastructure and buildings Further information For further information, please see the publication or contact Helmut Haberl (helmut.haberl@boku.ac.at).

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.

In this paper, the design of an event-driven user-centric middleware for monitoring and managing energy consumption in public buildings and spaces is presented. The main purpose is to increase energy efficiency in buildings and public spaces, thus reducing consumption. To achieve this, the proposed service-oriented middleware has been designed to be event based, also exploiting the user behavior patterns of people who live and work in buildings. Furthermore, it allows an easy integration of heterogeneous technologies in order to enable a hardware-independent interoperability between them. Moreover, a heating ventilation and air conditioning (HVAC) control strategy has been developed, and the whole infrastructure has been deployed in a real-world case study consisting of a historical building. Finally, the results will be presented and discussed.

In this study, we explore synergetic effects between biomass and CO2 utilization to reduce both GHG emissions and renewable resource use.

Los nuevos sistemas inteligentes para ayudar a la transición energética y mejorar la sostenibilidad y la vida de las personas se pueden implementar a diferentes escalas, desde una casa hasta una región entera. Los campus universitarios son un tamaño intermedio interesante (lo suficientemente grande como para importar y lo suficientemente pequeño como para ser manejable) para la investigación, el desarrollo, las pruebas y la capacitación sobre la integración de la inteligencia en todos los niveles, lo que llevó a la aparición del concepto de "campus inteligente" en los últimos años. Este artículo de revisión propone un amplio análisis de la literatura científica sobre campus inteligentes de la última década (2010-2020). Las 182 publicaciones seleccionadas se distribuyen en siete categorías de inteligencia: edificio inteligente, entorno inteligente, movilidad inteligente, vida inteligente, personas inteligentes, gobierno inteligente y datos inteligentes. Las principales preguntas y desafíos abiertos con respecto a los campus inteligentes se presentan al final de la revisión y abordan la sostenibilidad y la transición energética, la aceptabilidad y la ética, los modelos de aprendizaje, las políticas de datos abiertos y la interoperabilidad. El presente trabajo se realizó en el marco de la Red de Energía de la Cumbre de Líderes Regionales (RLS-Energy) como parte de sus esfuerzos de investigación multilateral sobre regiones inteligentes. De nouveaux systèmes intelligents pour aider à la transition énergétique et améliorer la durabilité et la vie des gens peuvent être déployés à différentes échelles, allant d'une maison à une région entière. Les campus universitaires sont une taille intermédiaire intéressante (assez grande pour compter et assez petite pour être maniable) pour la recherche, le développement, les tests et la formation sur l'intégration de l'intelligence à tous les niveaux, ce qui a conduit à l'émergence du concept de « campus intelligent » au cours des dernières années. Cet article de synthèse propose une analyse approfondie de la littérature scientifique sur les campus intelligents de la dernière décennie (2010-2020). Les 182 publications sélectionnées sont réparties en sept catégories d'intelligence : smart building, smart environment, smart mobility, smart living, smart people, smart governance et smart data. Les principales questions et défis ouverts concernant les campus intelligents sont présentés à la fin de l'examen et traitent de la durabilité et de la transition énergétique, de l'acceptabilité et de l'éthique, des modèles d'apprentissage, des politiques de données ouvertes et de l'interopérabilité. Le présent travail a été réalisé dans le cadre du Réseau de l'énergie du Sommet des dirigeants régionaux (RLS-Energy) dans le cadre de ses efforts multilatéraux de recherche sur les régions intelligentes. Novel intelligent systems to assist the energy transition and improve sustainability and people's life can be deployed at different scales, ranging from a house to an entire region. University campuses are an interesting intermediate size (big enough to matter and small enough to be tractable) for research, development, test and training on the integration of smartness at all levels, which led to the emergence of the concept of "smart campus" over the last few years. This review article proposes an extensive analysis of the scientific literature on smart campuses from the last decade (2010-2020). The 182 selected publications are distributed into seven categories of smartness: smart building, smart environment, smart mobility, smart living, smart people, smart governance and smart data. The main open questions and challenges regarding smart campuses are presented at the end of the review and deal with sustainability and energy transition, acceptability and ethics, learning models, open data policies and interoperability. The present work was carried out within the framework of the Energy Network of the Regional Leaders Summit (RLS-Energy) as part of its multilateral research efforts on smart regions. يمكن نشر أنظمة ذكية جديدة للمساعدة في انتقال الطاقة وتحسين الاستدامة وحياة الناس على مستويات مختلفة، تتراوح من منزل إلى منطقة بأكملها. تعتبر الجامعات ذات حجم متوسط مثير للاهتمام (كبيرة بما يكفي لتكون مهمة وصغيرة بما يكفي لتكون قابلة للتتبع) للبحث والتطوير والاختبار والتدريب على تكامل الذكاء على جميع المستويات، مما أدى إلى ظهور مفهوم "الحرم الجامعي الذكي" على مدى السنوات القليلة الماضية. تقترح مقالة المراجعة هذه تحليلاً شاملاً للأدبيات العلمية حول الجامعات الذكية من العقد الماضي (2010-2020). يتم توزيع المنشورات الـ 182 المختارة على سبع فئات من الذكاء: البناء الذكي، والبيئة الذكية، والتنقل الذكي، والمعيشة الذكية، والأشخاص الأذكياء، والحوكمة الذكية، والبيانات الذكية. يتم تقديم الأسئلة والتحديات الرئيسية المفتوحة المتعلقة بالحرم الجامعي الذكي في نهاية المراجعة والتعامل مع الاستدامة وانتقال الطاقة والقبول والأخلاقيات ونماذج التعلم وسياسات البيانات المفتوحة وقابلية التشغيل البيني. تم تنفيذ العمل الحالي في إطار شبكة الطاقة التابعة لقمة القادة الإقليميين (RLS - Energy) كجزء من جهودها البحثية متعددة الأطراف حول المناطق الذكية.

Abstract. Turkana, in northwest Kenya, is the country's poorest and least developed county. Pastoralism in Turkana is well adapted to the harsh climatic conditions but an increase in drought frequency associated with global climate change and intensifying violent conflicts between pastoral groups, poses significant challenges for local communities. The conflicts are especially violent in the border region between the Turkana and the Pokot communities. In this very region significant oil reserves have been found recently. The first aim of this paper is to analyse how the oil exploration affects the communities' vulnerability to climate change. Secondly, the paper explores the risk of the oil explorations to create new conflicts or aggravate existing ones. The primary method of the study is qualitative field research supplemented with a geo-spatial analysis of conflict data. The field research was conducted in October 2013 and April 2014 in three villages with different levels of engagement with the oil exploration. At the time of the research, oil exploration was expected close to Lokwamosing while it had recently started in the vicinity of Lopii and had been ongoing for a longer time close to Nakukulas. The findings suggest that the oil exploration increases the community's vulnerability to climate change. Further, unmet community expectations for water, employment and development pose a significant risk for violent conflict between local communities and the operating oil company. Intercommunal conflict over water and land could increase as well.

Reduced river runoff and expected upstream infrastructural developments are both potential threats to irrigation water availability for the downstream countries in Central Asia. Although it has been recurrently mentioned that a reduction in water supply will hamper irrigation in the downstream countries, the magnitude of associated economic losses, economy-wide repercussions on employment rates, and degradation of irrigated lands has not been quantified as yet. A computable general equilibrium model is used to assess the economy-wide consequences of a reduced water supply in Uzbekistan—a country that encompasses more than half of the entire irrigated croplands in Central Asia. Modeling findings showed that a 10–20 % reduction in water supply, as expected in the near future, may reduce the areas to be irrigated by 241,000–374,000 hectares and may cause unemployment to a population of 712–868,000, resulting in a loss for the national income of 3.6–4.3 %. A series of technical, financial, and institutional measures, implementable at all levels starting from the farm to the basin scale, are discussed for reducing the expected water risks. The prospects of improving the basin-wide water management governance, increasing water and energy use efficiency, and establishing the necessary legal and institutional frameworks for enhancing the introduction of needed technological and socioeconomic change are argued as options for gaining more regional water security and equity.
