Abstract

Food security has guided Russia’s food policy since 2010. The article examines the impact of food security policy on the food system. The Russian model of food security combines government intervention in the form of assistance for domestic production while simultaneously restricting market access. Food security does not appear to have a deleterious impact on the food system. We measure impact on four dimensions. Financial support for agriculture continues to increase in nominal rubles. In food production, the beef and dairy branches continue to lag, but increased grain production has made Russia a global leader in grain exports. Average per capita food consumption improved, although the poor consume much less, and the decline of the ruble affects the way Russians shop. The largest impact of food security has been on food trade. Food security policy has brought food to the forefront as an instrument of foreign policy. Food trade is politicized, witnessed by the food embargo against the West and food import bans against Turkey and Ukraine.  相似文献

Predictions of future requirements for the protection of maritime archaeological sites are made using the fetch method which has been developed to evaluate the quality of landing‐places and navigable channels. The very useful method may explain why archaeological sites along the coast are rare in some areas, but numerous in others. Many of them are vulnerable to destruction by the effects of climate change, especially rising sea‐levels, based on the IPCC scenarios. The objective fetch method can be used worldwide to predict where new finds of sites close to sea‐level can be expected, and also to predict a site's vulnerability.  相似文献

Protocols for photography of archaeological textiles to detect components of differing chemistry that are indicative of colourants were developed. Parameters of light source, camera distance, filter type, film type, film speed, and aperture size were evaluated for visible, UV-reflectance, UV-fluorescence, and infrared photography. Using these techniques facilitates selective sampling for further analysis that maximizes critical data acquisition while minimizing destruction of the artefact. Hence, forensic photography of archaeological perishable materials should be regarded as a precursor to destructive analytical methods.  相似文献

ABSTRACT

News, print and the associated communications were not just a booming business in the early modern period, but are – research-wise – a “hot topic” at this moment as well. The seven volumes discussed are syntheses of many years of research. The books show overlap due to geography and events, and their stress on news bearing media of various sorts, all within the seventeenth century. Each of the volumes is written by an expert on either the Baltic Sea, Germany, or the Dutch Republic. The foci vary from the exchange of information to the printing of newspapers and books, to the use of advertisements.  相似文献
