The impact of Russian food security policy on the performance of the food system

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.     

Droughts as random events in the Maya lowlands

Because the values of most of the parameters controlling the occurrence and severity of a drought in a given location are unknown, and no periodicity has been observed, droughts can be considered random events. Running a random number generator within the limits of the annual rainfall variability relevant to the Maya lowlands, and defining a “Lean Year”, it is observed that strings of lean years occur quite frequently. Defining “Severe Drought”, “Disaster”, and “Catastrophe” based on the length of these strings, it is observed that a severe drought occurs on average every 32 years, a disaster occurs on average every 130 years, and a catastrophe on average every 500 years. These values fit the measured variability of the Yucatan climate, as observed in lake core sediments and in the post conquest written records. It also fits the average occurrence of “megadroughts” in the US Great Plains.The fit between the random occurrence model and the actual, “measured” occurrence of droughts supports the notion that for all practical purposes, droughts had been random events in the Maya region and could not be predicted. The lack of evident periodicity could be one of the reasons why means for long-term storage of food products were not developed there. It may also have affected the relationship between the priesthood and the general populace in that region.Since the method described here can be applied to any climatic region once the rainfall variability and the sensitivity of the local agriculture are known or can be estimated, if similar results are found they may probably have affected other regions with other ancient cultures in a similar way.     

改革开放以后北京城镇居民食品消费生活的变化

改革开放以后的20年,北京城镇居民的食品消费生活经历了从勉强温饱到温饱再到小康状态的转变。在前一阶段,居民主要是追求吃的数量的扩充,主要特点是实现了从以“主食”消费为主向以“副食”消费为主的转化;在后一阶段,居民开始追求吃的质量的提高,营养、新鲜、方便、快捷的食品受到普遍欢迎。北京城镇居民食品消费生活的这种变化在某种程度上是中国居民生活水平普遍提高的反映,而中国绝大多数人的生活能够不断地得到改善,这一看似简单的现象正是中国渐进的社会主义改革不断取得成功的社会基础。     

Are rocks still water‐wet in the presence of dense CO2 or H2S?

The various modes of acid gas storage in aquifers, namely structural, residual, and local capillary trapping, are effective only if the rock remains water‐wet. This paper reports an evaluation, by means of the captive‐bubble method, of the water‐wet character in presence of dense acid gases (CO₂, H₂S) of typical rock‐forming minerals such as mica, quartz, calcite, and of a carbonate‐rich rock sampled from the caprock of a CO₂ storage reservoir in the South‐West of France. The method, which is improved from that previously implemented with similar systems by Chiquet et al. (Geofluids 2007; 7 : 112), allows the advancing and receding contact angles, as well as the adhesion behavior of the acid gas on the mineral substrate, to be evaluated over a large range of temperatures (up to 140°C), pressures (up to 150 bar), and brine salinities (up to NaCl saturation) representative of various geological storage conditions. The water‐receding (or gas‐advancing) angle that controls structural and local capillary trapping is observed to be not significantly altered in the presence of dense CO₂ or H₂S. In contrast, some alteration of the water‐advancing (or gas‐receding) angle involved in residual trapping is observed, along with acid gas adhesion, particularly on mica. A spectacular wettability reversal is even observed with mica and liquid H₂S. These results complement other recent observations on similar systems and present analogies with the wetting behavior of crude oil/brine/mineral systems, which has been thoroughly studied over the past decades. An insight is given into the interfacial forces that govern wettability in acid gas‐bearing aquifers, and the consequences for acid gas geological storage are discussed along with open questions for future work.

Eating,serving, and self-realisation: food and modern identities in contemporary Indian women's writing

The ‘new Indian woman’ is often invoked in popular and academic discourse as the embodiment of a modern nation—the ‘new India’. Feminist studies of this figure typically focus on the body of the imagined ‘new woman’ as a site upon which modernity is inscribed, allowing little room for the agency of women who actively contest imposed identities and roles in the quintessentially modern project of self-determination. In this article I argue that narratives of food in contemporary fiction and fictionalised autobiographical writing by Indian women challenge both dominant feminist critiques of the ‘new woman’, and influential accounts of modernity as ‘rupture’ in masculinist theoretical literature. In these texts food, and particularly the practice of serving food to others, is used by women as a tool for gaining independence, as a weapon to combat oppression, and as a means of negotiating migrant identities, among other things. The texts thus demonstrate the importance of appreciating the gendered nature of modernity, recognising women's modernities to be genuinely transformative of the individual, as well as continuous with traditional and conventionally feminine practices rather than necessarily opposed to them.     

Exploring children's foodscapes

In this article, we discuss children's becoming as food consumers in the intersection of various foodscapes. We draw from a project, Children as co-researchers of foodscapes, where we have been working with children as co-researchers, using basically ethnographic methods, and as co-designers in a collaborative design effort. This article focuses on the findings from a theoretically inspired perspective, using the concept of foodscapes. These are food-related structures of different kinds, which evolve as the child explores them and where children as food consumers are generated. In this article, we highlight the scapes of taste, routines, people, things, commerce, child (as opposed to adult) and health and give brief accounts of the way the children related to them. Finally, we turn to the benefits of working with foodscapes for a better understanding of children's becoming as food consumers in the intersection of various foodscapes. This article is based on data gathered by the children, but also on our fieldwork notes and observations following the children in their foodscapes.     

Natural flood management: small-scale progress and larger-scale challenges

ABSTRACT

Management of fluvial flood risk in the UK is undergoing a paradigm shift, with a change in emphasis from solely working with structural defences to considering catchment-based measures which attenuate flood runoff. Natural Flood Management (NFM) is promoted as a method that can reduce flood risk through the alteration, restoration or use of landscape features. Here we highlight the potential to manage runoff locally in the rural landscape using NFM by targeting flow pathways and utilising floodplains and riparian zones. Using two case study examples from the UK, we show that by accumulating dispersed small-scale storage in small catchment areas (<10 km²) can assist in attenuating flood runoff. However, there is currently a lack of evidence of measure effectiveness at larger catchment scales and for managing extreme flood events. Nevertheless, there is a strong evidence base to suggest many of these measures deliver a range of different ecosystem services if installed in the correct location in the landscape.     

Beyond Alternative: Exploring the Potential for Autonomous Food Spaces

Abstract: Much attention has been given in recent years to the rise of alternative food networks However, the very concept of “alternative” has come under increasing scrutiny, as theorists grapple with what is meant by alternative and whether the concept adequately captures the key components of such a diverse range of networks and communities. Drawing on poststructuralist political economy, I propose the concept of autonomous food spaces as one possible lens for approaches food‐provisioning activities that situate food within the broader context of non‐capitalist communities seeking to build relationships of mutual aid and non‐market exchanges. I use the examples of a radical collective kitchen, Food Not Bombs, and a community‐supported agriculture operation, Vegetables Unplugged, to explore the potential for autonomous food spaces as part of a broader “politics of possibilities” beyond capitalism.     

The Socio‐Nature of Local Organic Food

Abstract: The concept of socio‐nature asserts that social relations are inherently ecological and that ecological relations are inherently social. This paper examines how, and with what consequences, discourses and practices of support for local and organic food reflect this idea. It argues that proponents of local organic agriculture view the food they promote as simultaneously social and the product of human labor. However, advocates’ understanding of the concept is partial and constrained by social privilege. It does not extend to industrial agriculture or paid farm labor. The literature on socio‐nature coheres around the revelation that what is understood as natural is also social and vice versa. In contrast, this paper takes a new approach, examining socio‐nature as a practice‐shaping discourse already embedded in social life. Investigating the on‐the‐ground ideological work performed by the concept also allows for assessment of its political consequences.
