Los artículos reunidos en este documento se basan en las ponencias y comentarios de los expertos que participaron en el seminario regional Agricultura y Cambio Climático: Agrobiodiversidad, Agricultura Familiar y Cambio Climático, realizado el 20 y 21 de agosto de 2014 en la sede de la Comisión Económica para América Latina y el Caribe (CEPAL), en Santiago. El seminario tuvo como objetivo general “promover el diseño de mejores políticas públicas nacionales y regionales para potenciar el rol de la agro biodiversidad y de la agricultura familiar en la adaptación de la agricultura de América Latina y el Caribe al cambio climático”. Los objetivos específicos del seminario fueron: i) presentar enfoques conceptuales y experiencias de valoración de la agrobiodiversidad en la adaptación de la agricultura al cambio climático; ii) fomentar el diálogo de políticas en torno a la adaptación de la agricultura familiar al cambio climático; iii) presentar experiencias concretas de diversificación productiva y adaptación de la agricultura familiar al cambio climático; y iv) potenciar la cooperación regional en políticas de cuidado y promoción de la agrobiodiversidad y agricultura familiar en la adaptación al cambio climático.

Seguridad alimentaria, nutrición y erradicación del hambre CELAC 2025: elementos para el debate y la cooperación regionales

La región de América Latina y el Caribe ha mostrado una trayectoria exitosa en el proceso de erradicación del hambre y es la única región del mundo que redujo a la mitad tanto la proporción de personas que padecen hambre (meta establecida en los Objetivos de Desarrollo del Milenio) como el número absoluto de personas afectadas por el hambre (meta establecida en la Cumbre Mundial sobre la Alimentación, de 1996). El propósito de esta publicación es suministrar a los países de la región información actualizada y oportuna sobre el estado de la seguridad alimentaria y nutricional, el papel que tienen distintas áreas como la agricultura, el comercio agroalimentario y la gestión de recursos naturales en la erradicación del hambre y la posibilidad de enfrentar con éxito la doble carga de la malnutrición, en un contexto en que los efectos del cambio climático pueden amenazar los avances observados hasta el momento en América Latina y el Caribe. El Plan para la Seguridad Alimentaria, Nutrición y Erradicación del Hambre de la CELAC 2025 es una herramienta trascendental para el logro de los Objetivos de Desarrollo Sostenible de la Agenda 2030 para el Desarrollo Sostenible y, por ello, alienta a los países de América Latina y el Caribe a redoblar los esfuerzos para identificar las áreas clave de política que permitan acelerar y consolidar el proceso de erradicación del hambre y hacer frente a la doble carga de la malnutrición en la región, donde el sobrepeso y la obesidad se suman cada vez más a ese flagelo.

Food and nutrition security and the eradication of hunger CELAC 2025: Furthering discussion and regional cooperation

The region of Latin America and the Caribbean can boast a successful track record in the process of eradicating hunger: it is the only region in the world that has halved both the proportion of people who suffer from hunger (the target set in the Millennium Development Goals) and their absolute number (the target set at the World Food Summit of 1996). This publication aims to provide the region’s countries with up-todate and timely information on the status of food and nutrition security; on the role in eradicating hunger played by the different areas such as agriculture, agrifood trade and natural resources management; and on the possibility of successfully addressing the twin burden of malnutrition, in a context where the effects of climate change could threaten the progress achieved in Latin America and the Caribbean thus far. The CELAC Plan for Food and Nutrition Security and the Eradication of Hunger 2025 is a cross-cutting tool for achieving the Sustainable Development Goals of the 2030 Agenda for Sustainable Development; and it thus encourages the countries of Latin America and the Caribbean to redouble their efforts to identify key policy areas that will make it possible to speed up and consolidate the process of eradicating hunger and tackle the twin burden of malnutrition in the region, in which overweight and obesity are increasingly adding to that scourge.

Global standard for the composition of infant formula: Recommendations of an ESPGHAN coordinated international expert group

The Codex Alimentarius Commission of the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) develops food standards, guidelines and related texts for protecting consumer health and ensuring fair trade practices globally. The major part of the world's population lives in more than 160 countries that are members of the Codex Alimentarius. The Codex Standard on Infant Formula was adopted in 1981 based on scientific knowledge available in the 1970s and is currently being revised. As part of this process, the Codex Committee on Nutrition and Foods for Special Dietary Uses asked the ESPGHAN Committee on Nutrition to initiate a consultation process with the international scientific community to provide a proposal on nutrient levels in infant formulae, based on scientific analysis and taking into account existing scientific reports on the subject. ESPGHAN accepted the request and, in collaboration with its sister societies in the Federation of International Societies on Pediatric Gastroenterology, Hepatology and Nutrition, invited highly qualified experts in the area of infant nutrition to form an International Expert Group (IEG) to review the issues raised. The group arrived at recommendations on the compositional requirements for a global infant formula standard which are reported here.

CONFLITO GERACIONAL E A IDENTIDADE DOS JOVENS ADVENTISTAS DO SÉTIMO DIA: NEGAÇÃO OU RECONSTRUÇÃO DA IDENTIDADE ADVENTISTA POR PARTE DOS JOVENS

Este presente trabalho, tem por objetivo analisar o conflito geracional e a formação da identidade dos jovens adventistas, com o objetivo de verificar se o conflito geracional é uma demonstração que os jovens estão rompendo com a igreja ou, reconstruindo a identidade. O conflito geracional pode ser notado em diversas esferas da sociedade e inclusive dentro da Igreja Adventista. Todavia, o conflito geracional não é causado por rebeldia, mas sim, por diferentes maneiras de reagir e conviver com as características contemporâneas da sociedade. Sendo assim, os mais velhos não concordam com as novas propostas dos jovens e tão pouco, os mais novos desejam continuar convivendo com as coisas antigas. A Igreja Adventista tem vivido o conflito geracional em dois aspectos principais: o primeiro se evidencia na comunicação; o segundo na cosmovisão. A linguagem sofreu alterações na hora de se comunicar; no contexto atual, a imagem tomou a função das palavras. Por essa razão, uma comunicação pode não alcançar seu objetivo, principalmente aos mais novos, quando expressa somente através de palavras. O outro aspecto que tem causado conflito é a compreensão de mundo que os mais novos possuem. Para eles, o mundo não é sinônimo de pecado como algumas pessoas mais velhas entendem. Por conta desta diferença, certas questões não são aceitáveis dentro da igreja, por serem vinculadas ao mundo e o mundo ser entendido como pecado. Porém, a constatação que faço é que, embora o jovem não entenda o mundo em si como pecado, ele compreende que existem aspectos do mundo que sejam errados. Esses aspectos não são aceitáveis para eles e por isso, eles não desejam romper com a igreja. Mas estão em busca de mudanças significativas que se encaixam com sua visão de mundo. É possível evidenciar essa mesma linha de raciocínio em alguns líderes da igreja, mas os relatos dos jovens expressam que isso não alcançou a prática local. Uma vez que, concebo o pensamento de Hervieu-Leger de que a identidade não é transmitida intacta de pai para filho, mas construída individualmente. Entendo que os jovens estão formando sua própria identidade. Para que essa identidade seja formada de maneira sólida nos princípios adventistas, e aberta as mudanças necessárias da sociedade, se faz necessário, sob minha percepção, uma releitura de Ellen White baseada no pensamento liminar de Walter Mignolo, apresentado e explanado por Adolfo S. Suárez.

UMA ALIANÇA ABOMINÁVEL E PER/VERTIDA? ANOTAÇÕES SUBALTERNAS SOBRE O ARQUIVO DEUTERONÔMICO

O objetivo central desta pesquisa é avaliar os valores e possibilidades da aliança pregada no Deuteronômio. Para tanto, procuro captar a necessária tensão de qualquer tipo de aliança. Faço esse exercício, primeiramente, no próprio campo da hermenêutica. Sugiro uma leitura subalterna que agregue diferentes lutas no interior das interpretações libertárias (feminista, queer e pós-colonial). Nesse ínterim, forjo o trabalho do exegeta orgânico , a saber, aquele intérprete que articula vozes dissidentes para fazer frente às estruturas sistêmicas de subordinação. Após essa proposição teórica, avalio o Deuteronômio enquanto discursos concatenados em forma de arquivo. A principal sugestão é de que os textos deuteronômicos foram coletados ou produzidos em prol de um ideal de berit aliança . Esse ideal origina-se do material agora disposto em 4,44-26+28: um contrato comunitário atávico com Yhvh. Esse resultado é possibilitado pela crítica retórica ao texto e seus interesses propagandísticos desde o nascedouro arquivístico. Após uma comparação honesta com os tratados do Antigo Oriente Próximo, não se pode mais negar a pedagogia da obediência intrínseca ao contrato. A isso chamo, muitas vezes, de colusão do povo santo . A crítica retórica, entretanto, não encaminha apenas uma reificação desse ideal de berit, ao apontar, antes, para o debate interno da comunidade. Um contrato retórico, afinal, guarda em si, memórias silenciadas para que a propaganda se efetive. Nesse momento é que busco colisões de memórias, em especial, dentro das perícopes proibitivas do contrato. Todo o lixo deuteronômico, por assim dizer, está assinalado por duas fórmulas básicas: ki to abat yhvh eis uma abominação para Yhvh e ubi arta ha-ra mi-qirbeka exterminarás o per/vertido do teu meio . Dedico-me aos textos marcados por essas fórmulas, ao fomentar uma episódica unificação de abomináveis e per/vertidos . Avalio a luta particular de cada um/a, para então, propor uma agenda subalterna que promova a justiça social por reconhecimento e redistribuição. A aliança abominável e per/vertida intra-Deuteronômio apresenta uma proposta radicalmente democrática (i) em favor de uma cultura aberta ao Outro e (ii) contra estruturas autoritárias piramidais. Assinalo, portanto, que com essa dupla tática, os valores imperiais de hierarquização e subtração da irmandade deuteronômica são retoricamente postos em debate na comunidade.

Cadmium in the environment and high risk population groups

Cadmium has been widely used in various industries for the past fifty years, with current world production standing at around 16,755 tonnes per year. Very little cadmium is ever recycled and the ultimate fate of all cadmium is the environment. In view of reports that cadmium in the environment is increasing, this thesis aims to identify population groups 'at risk' of receiving dietary intakes of cadmium up to or above the current Food and Agricultural Organisation/World Health Organisation maximum tolerable intake of 70 ug/day. The study involves the investigation of one hundred households (260 individuals) who grow a large proportion of their vegetable diet in garden soils in the Borough of Walsall, part of an urban/industrial area in the United Kingdom. Measurements were made of the cadmium levels in atmospheric deposition, soil, house dust, diet and urine from the participants. Atmospheric deposition of cadmium was found to be comparable with other urban/industrial areas in the European Community, with deposition rates as high as 209 g ha-1 yr-1. The garden soils of the study households were found to contain up to 33 mg kg-1 total cadmium, eleven times the highest level usually found in agricultural soils. Dietary intakes of cadmium by the residents from food were calculated to be as high as 68 ug/day. It is suggested that with intakes from other sources, such as air, adventitious ingestion, smoking and occupational exposure, total intakes of cadmium may reach or exceed the FAO/WHO limit. Urinary excretion of cadmium amongst a non-smoking, non-occupationally exposed sub-group of the study population was found to be significantly higher than that of a similar urban population who did not rely on home-produced vegetables. The results from this research indicate that present levels of cadmium in urban/industrial areas can increase dietary intakes and body burdens of cadmium. As cadmium serves no useful biological function and has been found to be highly toxic, it is recommended that policy measures to reduce human exposure on the European scale be considered.

AllerTOP - a server for in silico prediction of allergens

Background: Allergy is a form of hypersensitivity to normally innocuous substances, such as dust, pollen, foods or drugs. Allergens are small antigens that commonly provoke an IgE antibody response. There are two types of bioinformatics-based allergen prediction. The first approach follows FAO/WHO Codex alimentarius guidelines and searches for sequence similarity. The second approach is based on identifying conserved allergenicity-related linear motifs. Both approaches assume that allergenicity is a linearly coded property. In the present study, we applied ACC pre-processing to sets of known allergens, developing alignment-independent models for allergen recognition based on the main chemical properties of amino acid sequences.Results: A set of 684 food, 1,156 inhalant and 555 toxin allergens was collected from several databases. A set of non-allergens from the same species were selected to mirror the allergen set. The amino acids in the protein sequences were described by three z-descriptors (z1, z2 and z3) and by auto- and cross-covariance (ACC) transformation were converted into uniform vectors. Each protein was presented as a vector of 45 variables. Five machine learning methods for classification were applied in the study to derive models for allergen prediction. The methods were: discriminant analysis by partial least squares (DA-PLS), logistic regression (LR), decision tree (DT), naïve Bayes (NB) and k nearest neighbours (kNN). The best performing model was derived by kNN at k = 3. It was optimized, cross-validated and implemented in a server named AllerTOP, freely accessible at http://www.pharmfac.net/allertop. AllerTOP also predicts the most probable route of exposure. In comparison to other servers for allergen prediction, AllerTOP outperforms them with 94% sensitivity.Conclusions: AllerTOP is the first alignment-free server for in silico prediction of allergens based on the main physicochemical properties of proteins. Significantly, as well allergenicity AllerTOP is able to predict the route of allergen exposure: food, inhalant or toxin. © 2013 Dimitrov et al.; licensee BioMed Central Ltd.

Land resource requirements for bioenergy in India

This study presents a two stage process to determine suitable areas to grow fuel crops: i) FAO Agro Ecological Zones (AEZ) procedure is applied to four Indian states of different geographical characteristics; and ii) Modelling the growth of candidate crops with GEPIC water and nutrient model, which is used to determine potential yield of candidate crops in areas where irrigation water is brackish or soil is saline. Absence of digital soil maps, paucity of readily available climate data and knowledge of detailed requirements of candidate crops are some of the major problems, of which, a series of detailed maps will evaluate true potential of biofuels in India.

Half-degree gridded nitrogen and phosphorus fertilizer use for global agriculture production during 1900-2013

In addition to enhance agricultural productivity, synthetic nitrogen (N) and phosphorous (P) fertilizer application in croplands dramatically altered global nutrient budget, water quality, greenhouse gas balance, and their feedbacks to the climate system. However, due to the lack of geospatial fertilizer input data, current Earth system/land surface modeling studies have to ignore or use over-simplified data (e.g., static, spatially uniform fertilizer use) to characterize agricultural N and P input over decadal or century-long period. We therefore develop a global time-series gridded data of annual synthetic N and P fertilizer use rate in croplands, matched with HYDE 3,2 historical land use maps, at a resolution of 0.5º latitude by longitude during 1900-2013. Our data indicate N and P fertilizer use rates increased by approximately 8 times and 3 times, respectively, since the year 1961, when IFA (International Fertilizer Industry Association) and FAO (Food and Agricultural Organization) survey of country-level fertilizer input were available. Considering cropland expansion, increase of total fertilizer consumption amount is even larger. Hotspots of agricultural N fertilizer use shifted from the U.S. and Western Europe in the 1960s to East Asia in the early 21st century. P fertilizer input show the similar pattern with additional hotspot in Brazil. We find a global increase of fertilizer N/P ratio by 0.8 g N/g P per decade (p< 0.05) during 1961-2013, which may have important global implication of human impacts on agroecosystem functions in the long run. Our data can serve as one of critical input drivers for regional and global assessment on agricultural productivity, crop yield, agriculture-derived greenhouse gas balance, global nutrient budget, land-to-aquatic nutrient loss, and ecosystem feedback to the climate system.

Usuários de crack, instituições e modos de subjetivação: estudo das práticas e da eficácia terapêutica em uma comunidade terapêutica religiosa (RN)

This anthropological research has as main goal to grasp the meanings and perceptions - mode of subjectivity - of crack users in relation to the proposals of Therapeutic Communities (TC) of religious character. The work emphasizes the analysis of Therapeutic Communities of Rio Grande do Norte state, studying a particular organization, called Anzóis da Dor. I intend to analyze qualitative data, focusing on an analysis of the discursive content of speeches and the observation of social interaction, which results in an ethnographic text characterized by a dense description. In relation to the dissertation’s specific goals, we seek to present a general overview of the emergence and development of Therapeutic Communities – encompassing general and local considerations - and pointing out to the dynamics of religious healing systems of these institutions, besides the principles that guide them. In methodological terms, I conducted the partial mapping of therapeutic communities located in Rio Grande do Norte state; interviews with Therapeutic Communities coordinators, visits, participant observation in one of these institutions as well as some interviews with crack users and people close to these social agents in relation to the Therapeutic Communities and the treatment offered by them
