Since 2004, the International Surface Ocean - Lower Atmosphere Study (SOLAS) project is an international research initiative aiming to understand the key biogeochemical-physical interactions and feedbacks between the ocean and atmosphere. Achievement of this goal is important to understand and quantify the role that ocean-atmosphere interactions play in the regulation of climate and global change. SOLAS celebrated its 10 year anniversary in 2014. In the first decade, the SOLAS community has accomplished a great deal towards the goals of the original Science Plan & Implementation Strategy and Mid-term Strategy (Law et al. 2013) as highlighted by the open access synthesis book on 'Ocean Atmosphere Interactions of Gases and Particles' edited by Liss and Johnson and the synthesis article in Anthropocene from Brévière et al. 2015. However there are still major challenges ahead that require coordinated research by ocean and atmospheric scientists. With this in mind, in 2013, SOLAS has started an effort to define research themes of importance for SOLAS research over the next decade. These themes form the basis of a new science plan for the next phase of SOLAS 2015-2025. SOLAS being a bottom-up organisation, a process in which community consultation play a central role was adopted. After two sets of reviews by our four sponsors (SCOR, Future Earth, WCRP and iCACGP), the SOLAS 2015-2025 Science Plan and Organisation (SPO) was officially approved.
The German dairy value chain is subject to profound structural change resulting in increasingly dominant agents at all stages of the chain, i.e. at the farm level, at the processors' level and at the retailers' level. In particular, the consolidation of retailers has increased retailers' bargaining power vis-à-vis their suppliers. Against this background, the overall objective of this subproject is to analyze the structural change in the dairy sector, particularly at the processors' level, by taking into account firms' strategic interactions along the entire dairy value chain. So far, there exists no theoretical workhorse model that allows for the analysis of interdependencies in a three-layer structure where imperfect competition is considered at all three stages. We aim to close this gap to understand how an increasingly dominant retail industry influences strategic decisions at the dairy processors' level which, in turn, may affect dairy farmers. Building upon a three-layer approach, we first examine whether processors have merger incentives to counter the retailers' bargaining power. We then analyze the differences between cooperatives and for-profit firms concerning their decision on product quality and the number of dairy suppliers. Finally, we assess the implications for upstream farmers which rounds off the picture of structural change in the German dairy sector.
In the last decades agricultural policy has gained increasingly in complexity. Nowadays it influences the food and agricultural sector from the global market down to the farm level. Widespread research questions, like the impact of the WTO negotiations on the farm structure, most often require comprehensive modeling frameworks. Thus, different types of models are utilized according to their comparative advantages and combined in a strategically useful way to more accurately represent micro and macro aspects of the food and agricultural sector. Consequently, in recent years we have seen an increase in the development and application of model linkages. Given this background, the overall objective of this subproject is a systematic sensitivity analysis of model linkages that gradually involves more and more characteristics of the linkage and the corresponding transfer of results between models. In addition, the project aims to answer the following specific question: How does structural change at the farm level influence aggregate supply and technical progress? Under which conditions is it possible to derive macro-relationships from micro-relationships? How does the aggregation level influence the model results and how can possible problems be overcome? This procedure is used to quantify the effects and to derive conditions for optimal interaction of the connected models. The analysis is based on the general equilibrium model GTAP (Global Trade Analysis Project) and the farm group model FARMIS (Farm Modelling Information System) which are employed in conjunction to analyze the effects of WTO negotiations on the farm level.
Ziel der Studie ist die Entwicklung eines Referenzszenarios im Gebäudebereich für das Gesamtziel 40Prozent CO2 -Einsparung bis 2020 , welches sich auf den deutschen Gebäudebestand und die CO2 -Emissionen im Jahr 1990 bezieht. Das Referenzszenario stellt die Wirkungen von Politikmaßnahmen für den Gebäudebereich dar, die bis zum 1.1.2010 implementiert worden sind. Grundsätzlich werden alle Gebäude der Sektoren Haushalte, Gewerbe-Handel-Dienstleistung betrachtet. In einer Szenarienrechnung vom Jahr 2010 bis zum Jahr 2020 werden die Effekte der bis zum 1.1.2010 in Kraft befindlichen Politikmaßnahmen fortgeschrieben. Neben dem Hauptszenario werden hier auch Sensitivitäten für veränderte Sanierungsraten, die fortschreitende Klimaerwärmung und den Einfluss der Bevölkerungsentwicklung berechnet. Die Berechnungen werden mit dem von Ecofys entwickelten Built-Environment-Analysis-Model BEAM durchgeführt. Wesentliche Ergebnisse der Szenarienrechnung sind Entwicklungen von Flächen, Heizwärmebedarfen, Endenergie- und Primärenergieverbräuchen sowie CO2-Emissionen. Darauf aufbauend werden die Zielerreichungen in Bezug auf die Emissionsminderungen im Zeitraum 1990-2020 sowie die Heizwärmebedarfsreduzierung im Zeitraum 2008-2020 erläutert. Weiterhin werden Vorschläge für weitere Politikinstrumente gemacht, die zusätzlich ergriffen werden könnten sowie der weitere Forschungsbedarf skizziert.
SP0 is conceived for coordination of the ICON research, for internal and external scientific exchange as well as for investigating development pathways of land use on the Philippines. The SP0 team will supervise the project activities as a whole, including reporting and final synthesis. It will design the ICON homepage, establish and maintain a web-based database and present the project and its results in scientific forums and public media. It will organize collaboration and scientific exchange with international networks dealing with atmospheric processes, global carbon, nitrogen, water and energy cycles, and long-term ecological research. Specifically, SP0 is devoted to ensuring a sound integration of the ICON project within the scientific communities of Germany and SE Asia. Supported by the ICON local research coordinator based at and employed by IRRI, it will coordinate with the IRRI farm management to assist other ICON subprojects with field setup, routine data collection and technical backstopping.
