| This year marks a centenary of the synthetic fertilizer industry. German chemists, Fritz Haber and Carl Bosch, in 1909 demonstrated their industrial process for the manufacture of ammonia. The achievement won them accolades including Nobel Prizes. The output of their Haber-Bosch process can be used for either peace or war, agriculture or munitions, and the rapid adoption by Germany of this industrial process is credited with prolonging WW1. Most of the synthetic nitrogenous fertilizer of the past century, and right up to the present, has been manufactured using the Haber-Bosch process. The use of synthetic fertilizers has led to significant negative environmental outcomes. Rudolf Steiner was an early voice against chemical agriculture. Steiner's... |

| Forest management to a large extent determines the possible services that the forest can provide. Different objectives in forest management determine the rotation length and valuation of different stages in forest succession. We present a method of mapping potential forest management at 1-km resolution to inform policy, land use modeling, and forest resource projections. The presented method calculates the suitability of a location to different forest management alternatives based on biotic, abiotic, socioeconomic, and political factors. A sensitivity analysis of the resulting map to the data sources used was performed. This showed that the results are very sensitive to some data sources. The potential use of the map and the sensitivity to the availability... |

| The Choleva agilis-group is revised. The three species are redescribed and their zoogeography is discussed. The phylogeny of the three species is hypothesized. Choleva jailensis Jeannel, 1923 and C. agilis clermonti van der Wiel, 1931 are new synonyms of C. agilis (Illiger, 1798). C. lederiana var. brevicollis Krogerus, 1926, is a new synonym of C. lederiana Reitter, 1901. The cavernicolous taxon gracilenta Szymczakowski, 1957, formerly regarded as a subspecies of C. lederiana, is transferred to C. septentrionis Jeannel, 1923. |

| Measurements of many hundreds of the high-crowned cheek teeth of Hystrix specimens from the Euro-Asiatic Pleistocene in the collections of European and Asiatic institutions have been compared with extant species for a revision of the genus. A review is given about the extant genera and species of the family. The number of recognisable Euro-Asiatic species in the fossil record is reduced from eight to five. The European H. (A.) vinogradovi Argyropulo, 1941 is here considered to be a synonym of H. (A.) brachyura Linnaeus, 1758, and the three Asiatic species H. (H.) crassidens Lydekker, 1886, H. (H.) gigantea Van Weers, 1985 and H. (H.) magna Pei, 1987 are synonymized with H. (H.) refossa Gervais, 1852. Most of the Chinese fossil specimens are properly... |

| En este trabajo se realiza un análisis comparado de dos métodos no paramétricos de medida de productividad total de los factores con datos de panel basados en programación: índices de Malmquist y un modelo DEA intertemporal que permite acotar las medidas de eficiencia y progreso técnico, suponiendo cambio técnico no regresivo. La aplicación se realiza sobre las agriculturas de los países de la Unión Europea, encontrándose algunas diferencias importantes entre ambos enfoques. Los resultados sugieren menor crecimiento de productividad agraria y, sobre todo, una ordenación distinta de países en relación con dichos crecimientos que los encontrados en otros trabajos.

| A bibliographic database of scientific papers published by authors affiliated to research institutions worldwide, especially focused in Europe and in the European Atlantic Area, and containing the keywords “microalga(e)” or “phytoplankton” was built. A corpus of 79,020 publications was obtained and analyzed using the Orbit Intellixir software to characterize the research trends related to microalgae markets, markets opportunities and technologies that could have important impacts on markets evolution. Six major markets opportunities, the production of biofuels, bioplastics, biofertilizers, nutraceuticals, pharmaceuticals and cosmetics, and two fast-evolving technological domains driving markets evolution, microalgae harvesting and extraction technologies... |

| The dense AlpArray network allows studying seismic wave propagation with high spatial resolution. Here we introduce an array approach to measure arrival angles of teleseismic Rayleigh waves. The approach combines the advantages of phase correlation as in the two-station method with array beamforming to obtain the phase-velocity vector. 20 earthquakes from the first two years of the AlpArray project are selected, and spatial patterns of arrival-angle deviations across the AlpArray are shown in maps, depending on period and earthquake location. The cause of these intriguing spatial patterns is discussed. A simple wave-propagation modelling example using an isolated anomaly and a Gaussian beam solution suggests that much of the complexity can be explained as... |

| The Emissions Trading scheme now (January 2003) in prospect in the European Union is likely to be the first trans-national greenhouse gas emissions trading scheme in the world. With the participation of the European Economic Area [EEA] countries and with the forthcoming EU enlargement, 30 countries could be involved in this scheme by 2012. Under European Union law, the European Commission is responsible for making proposals, which are then decided upon by the Council of Ministers - on a 'qualified majority' basis in this case - representing the 15 Member State governments, and the European Parliament. In the case of this Directive, the Commission prepared its initial proposals, which have then been scrutinised by the European Parliament and the Council... |

| n der Europäischen Union folgt beim Biolandbau ein Rekordjahr nach dem anderen. Die jüngsten konsolidierten Zahlen zeigen: Bio legte auch 2016 weiter zu und die für einzelne Länder zum Druckzeitpunkt vorliegenden Zahlen für 2017 belegen, dass der positive Trend sich fortsetzt. Der Biomarkt wuchs 2016 zweistellig auf über 30 Milliarden Euro und die Biofl äche stieg auf zwölf Millionen Hektar an. Fast alle großen Märkte verzeichneten zweistellige Wachstumsraten. Österreich hat die 20 Prozentmarke bei der Fläche längst überschritten und in Dänemark liegt der Biomarktanteil bei über zehn Prozent. Der nachfolgende Beitrag gibt zunächst einen Überblick über die Flächen-, Betriebs- und Marktentwicklung in Europa, benennt sodann die wichtigsten Gründe... |

| Using recent survey data (n = 1,430) on trust levels in agri-food supplier-buyer relationships in six different European countries, two commodity chains (meat and cereals) and two chain stages (farmer-processor and processor-retailer), main determinants of trust are identified and discussed. The structural equation modelling estimation results indicate that trust can be significantly improved by effective communication and by a positive collaboration experience. The existence of personal bonds does not seem to play a direct role in the retailer-processor relationship but is important when dealing with farmers. In both chain stages a positive collaboration experience as well the existence of personal bonds also indirectly enhance trust by promoting... |

| The Palaearctic species Caenopachys hartigii (Ratzeburg, 1848) has been collected in the National Park of Pollino (S Italy), which is the first exact confirmation for the Italian fauna. A brief nomenclatural history of the genus Caenopachys Foerster, 1862, is given, its status is discussed and it is elevated from synonymy. The type species is re-described and illustrated; a key to both West Palaearctic species is given, and some biological notes are added. |

| PrOOrg has the objective to develop a flexible and practicable Code of Practice (CoP) for processors of organic foods, as well as labelling organizations aiming to provide the operators with strategies and tools for making decisions that can help them to take the best choice for careful processing methods and formulations with a limited use of additives, while addressing the organic principles, high food quality, low environmental impact and high degree of consumer acceptance. |
