World food and agriculture: Outlook for the medium and longer term

The world has been making progress in improving food security, as measured by the per person availability of food for direct human consumption. However, progress has been very uneven, and many developing countries have failed to participate in such progress. In some countries, the food security situation is today worse than 20 years ago. The persistence of food insecurity does not reflect so much a lack of capacity of the world as a whole to increase food production to whatever level would be required for everyone to have consumption levels assuring satisfactory nutrition. The world already produces sufficient food. The undernourished and the food-insecure persons are in these conditions because they are poor in terms of income with which to purchase food or in terms of access to agricultural resources, education, technology, infrastructure, credit, etc., to produce their own food. Economic development failures account for the persistence of poverty and food insecurity. In the majority of countries with severe food-security problems, the greatest part of the poor and food-insecure population depend greatly on local agriculture for a living. In such cases, development failures are often tantamount to failures of agricultural development. Development of agriculture is seen as the first crucial step toward broader development, reduction of poverty and food insecurity, and eventually freedom from excessive economic dependence on poor agricultural resources. Projections indicate that progress would continue, but at a pace and pattern that would be insufficient for the incidence of undernutrition to be reduced significantly in the medium-term future. As in the past, world agricultural production is likely to keep up with, and perhaps tend to exceed, the growth of the effective demand for food. The problem will continue to be one of persistence of poverty, leading to growth of the effective demand for food on the part of the poor that would fall short of that required for them to attain levels of consumption compatible with freedom from undernutrition.

Role of the monkey ventrolateral prefrontal cortex in the integration of contextual information for the selection and understanding of goal-directed actions

Action selection and organization are very complex processes that need to exploit contextual information and the retrieval of previously memorized information, as well as the integration of these different types of data. On the basis of anatomical connection with premotor and parietal areas involved in action goal coding, and on the data about the literature it seems appropriate to suppose that one of the most candidate involved in the selection of neuronal pools for the selection and organization of intentional actions is the prefrontal cortex. We recorded single ventrolateral prefrontal (VLPF) neurons activity while monkeys performed simple and complex manipulative actions aimed at distinct final goals, by employing a modified and more strictly controlled version of the grasp-to-eat(a food pellet)/grasp-to-place(an object) paradigm used in previous studies on parietal (Fogassi et al., 2005) and premotor neurons (Bonini et al., 2010). With this task we have been able both to evaluate the processing and integration of distinct (visual and auditory) contextual sequentially presented information in order to select the forthcoming action to perform and to examine the possible presence of goal-related activity in this portion of cortex. Moreover, we performed an observation task to clarify the possible contribution of VLPF neurons to the understanding of others’ goal-directed actions. Simple Visuo Motor Task (sVMT). We found four main types of neurons: unimodal sensory-driven, motor-related, unimodal sensory-and-motor, and multisensory neurons. We found a substantial number of VLPF neurons showing both a motor-related discharge and a visual presentation response (sensory-and-motor neurons), with remarkable visuo-motor congruence for the preferred target. Interestingly the discharge of multisensory neurons reflected a behavioural decision independently from the sensory modality of the stimulus allowing the monkey to make it: some encoded a decision to act/refraining from acting (the majority), while others specified one among the four behavioural alternatives. Complex Visuo Motor Task (cVMT). The cVMT was similar to the sVMT, but included a further grasping motor act (grasping a lid in order to remove it, before grasping the target) and was run in two modalities: randomized and in blocks. Substantially, motor-related and sensory-and-motor neurons tested in the cVMTrandomized were activated already during the first grasping motor act, but the selectivity for one of the two graspable targets emerged only during the execution of the second grasping. In contrast, when the cVMT was run in block, almost all these neurons not only discharged during the first grasping motor act, but also displayed the same target selectivity showed in correspondence of the hand contact with the target. Observation Task (OT). A great part of the neurons active during the OT showed a firing rate modulation in correspondence with the action performed by the experimenter. Among them, we found neurons significantly activated during the observation of the experimenter’s action (action observation-related neurons) and neurons responding not only to the action observation, but also to the presented cue stimuli (sensory-and-action observation-related neurons. Among the neurons of the first set, almost the half displayed a target selectivity, with a not clear difference between the two presented targets; Concerning to the second neuronal set, sensory-and-action related neurons, we found a low target selectivity and a not strictly congruence between the selectivity exhibited in the visual response and in the action observation.

Família à mesa: com a palavra, mães e filhos

Introdução O comportamento alimentar do indivíduo resulta de decisões, conscientes ou não, relacionadas à cultura alimentar de sua região, à tradição alimentar de seu convívio social e às transformações decorridas do acesso à informação científica e popular. Objetivo Analisar a alimentação de adolescentes, residentes na região Norte do município de São José dos Campos (SP), na perspectiva da família. Materiais e métodos Estudo qualitativo, realizado em 2014 e 2015, com mães e adolescentes do 6o ano do ensino fundamental municipal. Dados sobre percepção, conhecimento, comportamento e barreiras para uma alimentação saudável dos adolescentes foram produzidos por meio de grupos focais. Entrevistas semiestruturadas foram realizadas com as mães dos estudantes para investigar aspectos sobre alimentação da família e relação com formação de práticas e comportamentos alimentares dos filhos. Os discursos foram registrados com auxílio de um gravador de voz, e transcritos posteriormente para análise, por meio da técnica de análise de conteúdo temática. Foram realizados 4 grupos focais com 6 estudantes cada, e 15 entrevistas com mães. Resultados e discussão Os discursos foram classificados em temas: comportamento alimentar, preferências alimentares e conhecimentos e crenças. Verificou-se que a alimentação dos adolescentes pode ser influenciada pelo comportamento alimentar dos pais. Mães e adolescentes percebemse conscientes e julgam sobre o que comem. Entretanto, a fala muitas vezes está distante da prática, seja por negligencia, dificuldade em perceber possibilidades de ação, questões emotivas ou pelo hábito formado, considerado a maior dificuldade para mudanças relacionadas à alimentação, tanto das mães quanto adolescentes. Possibilidades de soluções, quando referidas, eram por vezes permeadas por conflitos, causando insatisfação em mães e filhos. O contexto no qual esses individuos estão inseridos deve ser considerado, como o bairro e a escola, os quais contribuem para a determinação das escolhas alimentares. Conclusão a família exerce importante papel no comportamento alimentar de adolescentes, entretanto, a compreensão sobre o tema deve considerar, sobretudo, a cultura e o meio social em que a dinâmica familiar está contextualizada.

A first approach to earthquake damage estimation in Haiti: advices to minimize the seismic risk

This study is in the frame of the cooperative line that several Spanish Universities and other foreign partners started with the Haitian government in 2010. According to our studies (Benito et al. in An evaluation of seismic hazard in La Hispaniola, after the 2010 Haiti earthquake, 33rd General Assembly of the European Seismological Commission, Moscow, Russia, 2012) and recent scientific literature, the earthquake hazard in Haiti remains high (Calais et al. in Nat Geosci 3:794–799, 2010). In view of this, we wonder whether the country is currently ready to face another earthquake. In this sense, we estimated several damage scenarios in Port-au-Prince and Cap-Haitien associated to realistic possible major earthquakes. Our findings show that almost 50 % of the building stock of both cities would result uninhabitable due to structural damage. Around 80 % of the buildings in both cities have reinforced concrete structure with concrete block infill; however, the presence of masonry buildings becomes significant (between 25 and 45 % of the reinforced concrete buildings) in rural areas and informal settlements on the outskirts, where the estimated damage is higher. The influence of the soil effect on the damage spatial distribution is evident in both cities. We have found that the percentage of uninhabitable buildings in soft soil areas may be double the percentage obtained in nearby districts located in hard soil. These results reveal that a new seismic catastrophe of similar or even greater consequences than the 2010 Haiti earthquake might happen if the earthquake resilience is not improved in the country. Nowadays, the design of prevention actions and mitigation policies is the best instrument the society has to face seismic risk. In this sense, the results of this research might contribute to define measures oriented to earthquake risk reduction in Haiti, which should be a real priority for national and international institutions.

The Financialization of Food: An Inquiry into the 2008-2011 Food Price Spikes

This dissertation investigates the question: has financial speculation contributed to global food price volatility since the mid 2000s? I problematize the mainstream academic literature on the 2008-2011 food price spikes as being dominated by neoclassical economic perspectives and offer new conceptual and empirical insights into the relationship between financial speculation and food. Presented in three journal style manuscripts, manuscript one uses circuits of capital to conceptualize the link between financial speculators in the global north and populations in the global south. Manuscript two argues that what makes commodity index speculation (aka ‘index funds’ or index swaps) novel is that it provides institutional investors with what Clapp (2014) calls “financial distance” from the biopolitical implications of food speculation. Finally, manuscript three combines Gramsci’s concepts of hegemony and ‘the intellectual’ with the concept of performativity to investigate the ideological role that public intellectuals and the rhetorical actor the market play in the proliferation and governance of commodity index speculation. The first two manuscripts take an empirically mixed method approach by combining regression analysis with discourse analysis, while the third relies on interview data and discourse analysis. The findings show that financial speculation by index swap dealers and hedge funds did indeed significantly contribute to the price volatility of food commodities between June 2006 and December 2014. The results from the interview data affirm these findings. The discourse analysis of the interview data shows that public intellectuals and rhetorical characters such as ‘the market’ play powerful roles in shaping how food speculation is promoted, regulated and normalized. The significance of the findings is three-fold. First, the empirical findings show that a link does exist between financial speculation and food price volatility. Second, the findings indicate that the post-2008 CFTC and the Dodd-Frank reforms are unlikely to reduce financial speculation or the price volatility that it causes. Third, the findings suggest that institutional investors (such as pension funds) should think critically about how they use commodity index speculation as a way of generating financial earnings.

The Art of Enduring Contradictory Goals: Challenges in the Institutional Co‐construction of a ‘Good Death’

This paper focuses on the normative notion of ‘good death’, its practical relevance as a frame of reference for ‘death work’ procedures in institutional elder care in Switzerland and the ways in which it may be challenged within migrant ‘dying trajectories’. In contemporary palliative care, the concept of ‘good death’ focuses on the ideal of an autonomous dying person, cared for under a specialised biomedical authority. Transferred to the nursing home context, characterised by long-term basic care for the very old under conditions of scarce resources, the notion of ‘good death’ is broken down into ready-to-use, pragmatic elements of daily routines. At the same time, nursing homes are increasingly confronted with socially and culturally diversified populations. Based on ethnographic findings, we give insight into current practices of institutional ‘death work’ and tensions arising between contradicting notions of a ‘good death’, by referring to decision-making, life-prolonging measures, notions on food/feeding and the administration of sedative painkillers.

Pacific pandanus fruit: an ethnographic approach to understanding an overlooked source of provitamin A carotenoids

Commonly recommended plant sources of provitamin A, such as dark green leafy vegetables, are not acceptable in many population groups. The objective of this study was to identify other indigenous foods that may be effectively promoted to alleviate vitamin A deficiency (VAD) and to gather information relevant to identification, production, acquisition, and consumption of foods relevant to a food-based VAD prevention strategy in the Federated States of Micronesia. An ethnographic study on edible pandanus cultivars, involving key informant interviews and observation was carried out. Analyses revealed a great range in carotenoid content. Several orange-coloured pandanus cultivars, all highly acceptable, contained high levels of carotenoid, almost meeting daily requirements in usual consumption patterns, whereas light yellow-coloured cultivars contained low levels. Availability has decreased substantially in recent years due to increased consumption of imported foods and general neglect of indigenous foods. High-carotenoid pandanus should be promoted for general enjoyment and health benefits.

Cleaner fish, Labroides dimidiatus, diet preferences for different types of mucus and parasitic gnathiid isopods

Cleaner fish, Labroides dimidiatus, prefer the mucus of the parrotfish, Chlorurus sordidus, to parasitic gnathiid isopods, the main items in their diet, indicating a major conflict between clients and cleaners over what the latter should eat during interactions. We tested whether the conflict varied with client species (and the quality of its mucus) and with the presence of blood in the gnathfids. First, we offered cleaners the choice between mucus of the parrotfish and that of the snapper, Lutjanus fulviflamma. When offered equal amounts of mucus on Plexiglas plates, cleaners readily developed a significant preference for the parrotfish mucus. Reducing the amount of parrotfish mucus by 75% made the preference disappear. In a second test, we offered the cleaners gnathiids that were or were not engorged with client fish blood. Cleaners showed no significant preference for either food item. Our results suggest that the degree of conflict between cleaners and clients may vary between species, depending on whether the latter have a preferred mucus. In contrast, the cleaners' lack of preference for engorged gnathiids benefits clients because it means that cleaners do not hesitate to eat unengorged gnathiids before the gnathiids harm the fish by removing blood or by transmitting blood parasites.

Food and nutrient consumption patterns in third trimester Thai-Muslim pregnant women in rural Southern Thailand

The aims of this study were to determine food and nutrient intakes and the socio-economic factors influencing food and nutrient intakes of rural Thai-Muslim women in the third trimester of pregnancy. The study was conducted in Pattani province, Thailand, where 166 women were interviewed between 32 and 40 weeks gestation. A questionnaire. including a Food Frequency Questionnaire was used. Data on food items were compiled into the five basic Thai food groups, and food intakes were computed into macro and micro-nutrients. Mean weight intake of each of the five groups was below the recommended level for pregnant Thai women. Mean intake of niacin, vitamin A (RE) and vitamin C were above the recommended Thai level. Thiamin, calcium. phosphorus and iron intakes were lower than 50% of recommended levels. Intakes of the five food groups were not associated with socio-economic status, although total non-haem iron intake was associated with level of education. Under-consumption of food and nutrients among pregnant women in the study area was due to poor education. poverty and food availability. Integrated strategies should be considered to promote increased intakes to meet nutrient recommendations.

Dietary ecology of the Australian freshwater turtle (Elseya sp.: Chelonia : Chelidae) in the Burnett River, Queensland

The Burnett River snapping turtle (Elseya sp.) from the Burnett, Mary and Fitzroy river systems is an undescribed Australian freshwater turtle, of which very little ecological information is known. This paper describes the dietary ecology of the species in the Burnett River catchment. Stomach and faecal samples were collected from turtles and an index of relative importance was used to rank food items found in stomach samples. This index indicated that algae and aquatic ribbon weed (Vallisneria) were the dominant food items consumed. No difference in diet was found between males and females. Although the sample size was small, diet appeared to vary slightly seasonally, with Elseya sp. selectively feeding on the flower buds of the Chinese elm tree (Celtis chinensis) and the seeds of the blackbean tree (Castanospermum australe) when these food items were seasonally available. Faecal samples suggest that the most ingested foods ( algae and aquatic ribbon weed) were also the most digestible. Although predominantly herbivorous, Elseya sp. was seen to eat carrion once in the wild.

Do adaptors and innovators subscribe to opposing values?

Many studies reveal that adaptors are more ready to accept the status quo, whereas innovators are less likely to do so. This raises the question: Do adaptors and innovators subscribe to opposing values? A study is conducted with the following hypotheses. H1 predicts that adaptors are more likely to subscribe to CONSERVATION values like security, conformity, and tradition. H2 predicts that innovators are more likely to subscribe to OPENNESS TO CHANGE values like self-direction and stimulation. The respondents consisted of 243 students from Singapore with an average age of 17.9 years and 195 students from Australia with an average age of 19.1 years. These respondents answered a survey that contained the Kirton Adaption-Innovation (KAI) inventory and the Schwartz value survey. For the Singapore sample, KAI was negatively correlated with CONSERVATION: r = -39, p <.0001; but it was positively correlated with OPENNESS TO CHANGE: r = .14, p <.05. For the Australian sample, KAI was negatively correlated with CONSERVATION: r = -.15, p <.05; but it was positively correlated with OPENNESS TO CHANGE: r =.32, p <.0001. A standard regression analysis indicated that CONSERVATION was the most significant predictor (P = -.43, p <.0001) of KAI, followed by OPENNESS TO CHANGE (P =.37, p <.0001) and Nationality (P =.21, p <.0001). The significant finding associated with Nationality could be attributed to the fact that the Singaporean respondents were a highly select and innovative group of individuals who were aspiring to work in the media industry.
