This paper examines the effects that windfalls from international commodity price booms have on net foreign assets in a panel of 145 countries during the period 1970-2007. The main finding is that windfalls from international commodity price booms lead to a significant increase in net foreign assets, but only in countries that are ethnically homogeneous. In highly ethnically polarized countries, net foreign assets significantly decreased. To explain this asymmetry, the paper shows that in ethnically polarized countries commodity windfalls lead to large increases in government consumption expenditures and political corruption. The paper's findings are consistent with theoretical models of the current account that have a built-in voracity effect.

The propriety & findings of various indices of European Union (EU) voting power are discussed with respect to previous research by Jan-Erik Lane & Reinert Maeland (1995), & Lane, Maeland, & Sven Berg (1995), drawing on applications of various normalized & unnormalized indices. Following a brief explication of the misapplications of the normalized Banzhaf index by Lane & Maeland, it is argued that these mistakes led to inaccurate perceptions of the size of the European Parliament (EP) following German reunification & the considerable difference between the double qualified majority rule & the unanimity rule. Further, the previous research wrongly assumes that all independent members of the EP act as one group. It is suggested that the choice of power index influences the conclusions regarding national voting power. 2 Tables, 1 Figure. T. Sevier

A rapidly growing share of global agricultural areas is devoted to the production of biomass for non-food purposes. The derived products include, for example, biofuels, textiles, detergents or cosmetics. Given the far-reaching global implications of an expanding non-food bioeconomy, an assessment of the bioeconomy's resource use from a footprint perspective is urgently needed. We determine the global cropland footprint of non-food products with a hybrid land flow accounting model combining data from the Food and Agriculture Organization and the multi-regional input-output model EXIOBASE. The globally interlinked model covers all cropland areas used for the production of crop- and animal-based non-food commodities for the years from 1995 to 2010. We analyse global patterns of raw material producers, processers and consumers of bio-based non-food products, with a particular focus on the European Union. Results illustrate that the EU is a major processer and the number one consumer region of non-food cropland, despite being only the fifth largest producing region. Two thirds of the cropland required to satisfy EU non-food consumption are located in other world regions, giving rise to a significant dependency on imported products and to potential impacts on distant ecosystems. With almost 29% in 2010, oilseed production, used to produce, for example, biofuels, detergents and polymers, represents the dominant share in the EU's non-food cropland footprint. There is also a significant contribution of more traditional non-food biomass uses such as fibre crops (for textiles) and animal hides and skins (for leather products). Our study emphasises the importance of comprehensively assessing the implications of the non-food bioeconomy expansion as envisaged in various policy strategies, such as the Bioeconomy Strategy of the European Commission.

With this UFOPLAN project on land use indicators, the German Federal Environment Agency aimed at further developing indicators from a consumption perspective in support of Germany's sustainability strategy, covering both area-based and impact-oriented land footprint indicators.The project also aimed at calculating selected land footprint indicators for Germany and the EU. These indicators should provide an improved understanding of the global teleconnections of consumption and land use relevant for policy making towards achieving sustainable land use. This synthesis report presents the key results from this project. First, we present a structured overview of existing approaches for estimating land footprintsand describe their technical and structural characteristicsas well as their strengths and weaknesses. This leads to the specification of a hybrid methodology as the preferred calculation approach. In the second part, we present the developed innovative hybrid land footprint method, consisting of a global land flow accounting and trade model capturing commodity flows in physical units to track embodied land along global supply chains. For non-food commodities the supply chains were complemented by an environmental input-output model. This method was used to calculate the cropland, grassland and forestland footprint of Germany and the EU. Finally, an overview of existing indicator systems for representing the environmental impacts of land use was provided and their complementary usage to extend area-based land footprints was discussed. A few of these complementary indicators were also quantified, most notably the deforestation footprint. The synthesis report closes with an overview of the thematic areas that need to be addressed in future research.

A rapidly growing share of global agricultural areas is devoted to the production of biomass for non-food purposes. The expanding non-food bioeconomy can have far-reaching social and ecological implications; yet, the non-food sector has attained little attention in land footprint studies. This paper provides the first assessment of the global cropland footprint of non-food products of the European Union (EU), a globally important region regarding its expanding bio-based economy. We apply a novel hybrid land flow accounting model, combining the biophysical trade model LANDFLOW with the multi-regional input-output model EXIOBASE. The developed hybrid approach improves the level of product and country detail, while comprehensively covering all global supply chains from agricultural production to final consumption, including highly-processed products, such as many non-food products. The results highlight the EU's role as a major processing and the biggest consuming region of cropland-based non-food products while at the same time relying heavily on imports. Two thirds of the cropland required to satisfy the EU's non-food biomass consumption are located in other world regions, particularly in China, the US and Indonesia, giving rise to potential impacts on distant ecosystems. With almost 39% in 2010, oilseeds used to produce for example biofuels, detergents and polymers represented the dominant share of the EU's non-food cropland demand. Traditional non-food biomass uses, such as fibre crops for textiles and animal hides and skins for leather products, also contributed notably (22%). Our findings suggest that if the EU Bioeconomy Strategy is to support global sustainable development, a detailed monitoring of land use displacement and spillover effects is decisive for targeted and effective EU policy making.
