Agriculture provides the most essential service to mankind, as production of crops in sufficient amounts is necessary for food security and livelihood. This chapter examines the question of whether organic agriculture can produce enough food to meet future demand. This question relates to a moral imperative and any evaluation must therefore be based on objective scientific facts excluding ideological bias, political correctness, economic incentives or environmental opinions. The chapter begins by defining the conditions necessary for a stringent evaluation of crop yields and explains potential pitfalls. Yield data from national statistics, organic and conventional long-term experiments and comparative studies are then compiled and evaluated, followed by a discussion of the main factors behind low-yielding production. In a global perspective, the scientific literature shows that organic yields are between 25 and 50% lower than conventional yields, depending on whether the organic system has access to animal manure. The amount of manure available on organic farms is usually not sufficient to produce similar crop yields as in conventional systems and therefore green manures are commonly used. However, organic crop yields reported for rotations with green manure require correction for years without crop export from the field, which reduces average yield over the crop rotation. When organic yields are similar to those in conventional production, nutrient input through manure is usually higher than nutrient addition in conventional agriculture, but such high inputs are usually only possible through transfer of large amounts of manure from conventional to organic production. The main factors limiting organic yields are lower nutrient availability, poorer weed control and limited possibilities to improve the nutrient status of infertile soils. It is thus very likely that the rules that actually define organic agriculture, i.e. exclusive use of manures and untreated minerals, greatly limit the potential to increase yields. Our analysis of some yield-related statements repeatedly used by advocates of organic agriculture reached the following conclusions: Organic manure is a severely limited resource, unavailable in quantities sufficient for sustaining high crop yields; legumes are not a free and environmentally sound N source that can replace inorganic fertilisers throughout; and low native soil fertility cannot be overcome with local inputs and untreated minerals alone. Agricultural methods severely limiting crop yields are counter-productive. Lower organic yields require compensation through expansion of cropland – the alternative is famine. Combining expected population growth and projected land demand reveals that low-yielding agriculture is an unrealistic option for production of sufficient crops in the future. In addition, accelerated conversion of natural ecosystems into cropland would cause significant loss of natural habitats. Further improvement of conventional agriculture based on innovations, enhanced efficiency and improved agronomic practices seems to be the only way to produce sufficient food supply for a growing world population while minimising the negative environmental impact.

Military preparedness and war have so far been regarded as the domain of male authors in Swedish literature, especially at the time of the Second World War. But what happens if we turn our attention to the female authors of the 1940s? Kristin Järvstad's study shows how their texts as well focus to a large extent on subjects related to military preparedness and war. A variety of topics can be found in the novels by the female writers, ranging from stories about female air guards who protect the Swedish border to female pacifists who find it necessary to kill for the sake of peace. The soldier figure in these texts also takes a radical stand when he as a deserter lays down his arms to protest against the war. In addition, one of the most charged subjects of the time linked to gender is treated from a unique perspective: the women who consort with the occupying enemy are pictured without the condemning attitude that characterizes the period in general. The most urgent question, however, concerns alienation, linked to race: who is actually included in the Swedish nation? Here, the texts display a scathing critique of the narrow-minded Swedes and the anti-Semitism that flourishes at that time. By analysing female authors' depictions of the 1940s, During Military Preparedness and War deepens the previous picture of this period in Swedish literature. The writers explored in this investigation express a profound and often critical commitment to the issue of war and violence, linked to gender and alienation. The most radical literary message of the period can also be found among their novels: the demand for the dissolution of the militaristic and patriarchal nation which strives to expand its territory without regard for human life.

Zoi Mella, The Greek Civil War and the Spanish Press during Franco's DictatorshipIn this article we would like to approach a quite unknown subject: the presence of the Greek Civil War in the Spanish Press. Our objective was to ascertain the impact this event had at the post war Spanish Press. How would react Spain in view of such a confrontation, especially since it had already experimented a Civil War? It was a complicated period for Greece, as well as for Spain, a time when both countries experienced problems of different nature but equally serious: Greece was suffering the devastating consequences of the Second World War and Spain was trying to encounter the contempt of the international political world. The Greek Civil War was the first confrontation between two worlds that were exiting reinforced from the Second World War. It became the field of conflict between the USSR and the Anglo-Saxon allies during several years. The interior problem of some rebels, who couldn't, or wouldn't, adapt themselves to the new post war situation or were discontented with the new regime, was transformed to an international matter of great impact, that managed to confront USSR, on one hand, and the US and Great Britain, on the other, in the International Organism of the United Nations. Our interest was centred in the various approaches that the newspapers and the magazines of the time made. Moreover we were interested in the points of view and the conclusions manifested by the diverse papers, according to their political and ideological affinities, without forgetting the strict regime of control and censure that was in force at that moment. This investigation forms part of a broader subject that is the bilateral relations of these two countries, rather different at first sight, that during the XX century were affected by very similar events, such as a civil war. ; Zoi Mella, The Greek Civil War and the Spanish Press during Franco's DictatorshipIn this article we would like to approach a quite unknown subject: the presence of the Greek Civil War in the Spanish Press.
