An optimal network design was carried out to prioritise the installation or refurbishment of greenhouse gas (GHG) monitoring stations around Africa. The network was optimised to reduce the uncertainty in emissions across three of the most important GHGs: CO2, CH4, and N2O. Optimal networks were derived using incremental optimisation of the percentage uncertainty reduction achieved by a Gaussian Bayesian atmospheric inversion. The solution for CO2 was driven by seasonality in net primary productivity. The solution for N2O was driven by activity in a small number of soil flux hotspots. The optimal solution for CH4 was consistent over different seasons. All solutions for CO2 and N2O placed sites in central Africa at places such as Kisangani, Kinshasa and Bunia (Democratic Republic of Congo), Dundo and Lubango (Angola), Zoétélé (Cameroon), Am Timan (Chad), and En Nahud (Sudan). Many of these sites appeared in the CH4 solutions, but with a few sites in southern Africa as well, such as Amersfoort (South Africa). The multi-species optimal network design solutions tended to have sites more evenly spread-out, but concentrated the placement of new tall-tower stations in Africa between 10ºN and 25ºS. The uncertainty reduction achieved by the multi-species network of twelve stations reached 47.8% for CO2, 34.3% for CH4, and 32.5% for N2O. The gains in uncertainty reduction diminished as stations were added to the solution, with an expected maximum of less than 60%. A reduction in the absolute uncertainty in African GHG emissions requires these additional measurement stations, as well as additional constraint from an integrated GHG observatory and a reduction in uncertainty in the prior biogenic fluxes in tropical Africa.

In order to effectively tackle the on-going changes in global climate, stakeholders and policy makers across the globe need timely and accurate information they can trust on a wide range of topics. Here we briefly describe how observational data on greenhouse gas concentrations collected from the ICOS network of measurement stations in Europe is transformed via atmospheric modelling into information on how emission and uptake of greenhouse gases vary over time and space, and interpreted by experts to create knowledge usable by decision makers.

This chapter examines the different legal remedies available under EU law for the legal persons whose position has been affected by the acts adopted by the EU institutions as a part of the different legal instruments built in order to counter the economic crisis. This will be done through an analysis of the recent case law of the Court of Justice, structured in three steps. In the first step, we will examine the possibility to obtain the annulment of the act, having regard of the main legal instrument provided by the Treaties for this purpose (the action for annulment in Art. 263 of the TFEU). In the second step, we will explore the possibility of invoking in front of the Court of Justice an action for damages against the institution concerned. In the third, concluding step, we will look at the remedies at national level, looking at two cases where the Court of Justice has scrutinized the validity of implementing national measures in light of EU law.

Demonstrating the ways in which the micro and macro-economic constitutions of Europe have reacted to legal measures enacted to counter the economic crisis of the past decade, this innovative book takes an interdisciplinary approach in its attempt to understand and portray the metamorphosis of the European Economic Constitution. It contains contributions from leading scholars and experts in European economic law, discussing the challenges, solutions found, problems arising and possible approaches to embed the economic constitution in the broader constitutional framework of the EU.
