Title A name given to the resource Modelación de la respuesta hidrológica al cambio climático: experiencias de dos cuencas de la zona centro-sur de Chile Creator An entity primarily responsible for making the resource José Luis Arumí, Alejandra Stehr, Patrick Debels, Hernán Alcayaga, Francisco Romero Description An account of the resource Durante los últimos años se ha observado un cambio progresivo de las condiciones climáticas en el mundo, que ha tenido como consecuencia aumentos de la frecuencia y severidad de fenómenos, como inundaciones y sequías. Por lo anterior, es necesario contar con herramientas que permitan tomar decisiones de manera informada. Una forma de evaluar el efecto de un cambio en las precipitaciones y temperaturas respecto de la disponibilidad de agua de una cuenca es utilizar un modelo hidrológico distribuido, el cual, una vez calibrado y validado, es perturbado con cambios (% variación precipitación y Δ de cambio en la temperatura) obtenidos de distintos escenarios climáticos futuros. El objetivo de este trabajo consiste en cuantificar, a partir de simulaciones realizadas mediante un modelo matemático, la sensibilidad de la hidrología de dos subcuencas del río Biobío frente a un amplio set de plausibles escenarios de cambio climático. Además se analiza la amplitud en la respuesta del modelo hidrológico obtenido a partir de los distintos escenarios derivados directamente de diferentes modelos de circulación global (MCG), evaluándose también el impacto de usar variaciones de precipitación y temperatura obtenidas de un modelo de circulación Regional (MCR). Los resultados indican que, para la mayor parte de los escenarios de cambio climático modelados, se producirá una reducción en la magnitud de los caudales medios mensuales y anuales, siendo esta variación mayor en las épocas de primavera y verano. Estos resultados permiten realizar una primera interpretación cualitativa de los potenciales impactos del cambio climático en la disponibilidad de los recursos hídricos en la cuenca del río Biobío.

Title A name given to the resource Alternativas nutricionales eficientes en banano orgánico en la provincia El Oro, Ecuador Creator An entity primarily responsible for making the resource Edgar Lenin Valverde Fonseca, Rigoberto Miguel García Batista, Alexander Moreno Herrera, Alejandro Rafael Socorro Castro Description An account of the resource La problemática de implementar alternativas nutricionales en las plantaciones bananeras es un caso significativo que se presenta como prioridad productiva, social y económica al implementar una agricultura orgánica, limitando el uso de químicos que contaminan las cosechas y el medio ambiente de manera general. El cultivo tradicional del banano utiliza altas dosis de fertilizantes químicos, especialmente Nitrógeno y Potasio, lo que propicia buscar alternativas nutricionales y manejar las plantaciones en una forma más sostenible. La producción de banano orgánico en las áreas de producción tradicional conlleva cambios en la tecnología del cultivo, donde para mantener los requerimientos nutricionales del cultivo y garantizar una producción eficiente, en la que se elevan los costos, se hace necesaria la implementación de nuevas alternativas para lograr un producto de calidad y elevado valor de venta, lo que garantizaría el éxito de las producciones orgánicas, lo que han conllevado a cumplimentar los siguientes objetivos: Relacionar las diferentes fuentes de residuos orgánicos empleadas como suministros de nutrimentos alternativos para plantaciones de banano orgánico y describir alternativas de fertilización orgánica para mantener los requerimientos nutricionales en plantaciones de banano orgánico.

Title A name given to the resource Agroecologia nas políticas públicas e promoção da segurança alimentar e nutricional Creator An entity primarily responsible for making the resource Iracema Ferreira de Moura, Cláudia de Souza, Flaviane Canavesi Description An account of the resource O artigo tem como objetivo apontar avanços, limites e desafios em relação àinstitucionalização da agroecologia no Brasil na perspectiva da garantia da segurança alimentar e nutricional. Para isso, apresentam-se e analisam-se o marco jurídico institucional e as principais políticas públicas que estabelecem as bases para tratar ambos os temas na agenda de governo. O período de análise compreende desde a Política Nacional de Assistência Técnica, em 2003, até o decreto da Política Nacional de Agroecologia e Produção Orgânica, em 2012. No Brasil, vigora a Lei Orgânica de Segurança Alimentar e Nutricional no 11.346/2006, cujas ações de governo em torno do tema culminam com o Direito Humano àAlimentação Adequada. Desde a década de 1980, o movimento agroecológico brasileiro reivindica políticas públicas efetivas para o desenvolvimento rural, na perspectiva da construção de um novo modelo de agricultura em bases sustentáveis, consolidado, sobretudo, pela agricultura familiar. No entanto, somente em 2012, instituiu-se a Política Nacional de Agroecologia e Produção Orgânica com grande interface com as ações de segurança alimentar e nutricional num contexto da hegemonia do agronegócio voltado à exportação de commodities como fator limitante, tanto da transição agroecológica, quanto na garantia da segurança alimentar e nutricional.

Title A name given to the resource Las Mujeres y el Mito de la Agricultura de Subsistencia. De la exportación de alimentos a la dependencia alimentaria en el sur de Mozambique Creator An entity primarily responsible for making the resource Albert Farré Description An account of the resource As in many African countries, agriculture has been one of the key issues when debating rural development in Mozambique. One of the current concepts in these debates is the so called subsistence agriculture. In this article we propose an historical perspective to look at changes in rural areas of Southern Mozambique before colonialism, during colonialism and after the independence. By focusing on the evolution of rural markets, social inequalities, kin and other hierarchies that structure rural societies, we propose that concepts as subsistence agriculture and family sector, if used without taking into account historical changes, tend to simplify too much ever changing rural complexities. We conclude that history can help in socioeconomic analysis and a better diagnosis for future policies.

Title A name given to the resource Ecología trófica del jabalí europeo (Sus scrofa) silvestre en Chile Trophic ecology of the wild boar (Sus scrofa) in Chile Creator An entity primarily responsible for making the resource FABIÁN M. JAKSIC, ÓSCAR SKEWES, ROBERTO RODRÍGUEZ Description An account of the resource Documentamos la dieta del jabalí silvestre en el centro-sur de Chile basados en el examen de 20 estómagos colectados en los faldeos de volcán Mocho-Choshuenco (39°54' S, 72°02' O) y en el Parque Nacional Vicente Pérez Rosales (41°03' S, 71°54' O). La dieta está representada por animales, vegetales y hongos. Entre los vegetales y hongos son consumidas tanto las partes epígeas como hipógeas, lo mismo que frutos y semillas. Hongos y rizomas de Gunnera tinctoria constituyen ítemes vegetales cuantitativamente importantes en la alimentación. El jabalí forrajea en general en ambiente boscoso, pero las especies vegetales más frecuentes en la dieta se encuentran en espacios abiertos o fuera del bosque. El ambiente dominado por Chusquea spp. constituye un importante sitio de alimentación. Los roedores de la familia Muridae dominan entre los animales determinados en la dieta del jabalí. Esta situación, sin embargo, parece obedecer a la ocurrencia de una ratada producto de la semillación masiva de Chusquea spp. durante la época de muestreo. Las aves de la familia Rhinocryptidae e invertebrados (en especial larvas del coleóptero Chiasognathus grantii) constituyen parte frecuente de los ítemes animales de la dieta del jabalí. En comparación a estudios en otras partes del mundo, el jabalí silvestre en Chile consume hongos en porcentaje de ocurrencia similar (65 %) a su dieta en Estados Unidos de América pero bastante más alta que su dieta en Europa (5-32 %). En relación al volumen del componente animal, el jabalí en Chile consume más (16,1 %) que en Estados Unidos de América (6 %) y que en Europa (7-13 %)We document the diet of wild boar in south-central Chile based on analysis of 20 stomachs collected on the outskirts of Mocho-Choshuenco volcano (39°54' S, 72°02' W) and of Vicente Pérez Rosales National Park (41°03' S, 71°54' W). The diet incorporates animals, plants and fungi. Among the latter two, both epigeal and hypogeal parts are consumed, together with fruits and seeds. Fungi and rhizomes of Gunnera tinctoria are the most abundant plant items in the diet. The wild boar in Chile forages chiefly in forested environments, but nonetheless the most frequent plant items in its diet are found in open spaces or outside the forest. Environments dominated by bamboos Chusquea spp. constitute important foraging sites. Rodents in the family Muridae prevail among animal items in the wild boar diet. This situation, however, is associated to the occurrence of a mouse outbreak (ratada) resulting from the mast seeding of Chusquea spp. during our study. Birds in the family Rhinocryptidae together with invertebrates (specially Coleopteran larvae of Chiasognathus grantii) made up a sizeable part of the animals in the wild boar diet. In comparison to elsewhere, the wild boar in Chile consumes fungi in a similar percentage of occurence (65 %) as in the United States of America but much higher than in Europe (5-32 %). With regard to the animal component, the wild boar in Chile consumes more (20 % volume) of such items than in the United States of America (6 %) and in Europe (7-13 %) Date A point or period of time associated with an event in the lifecycle of the resource 2007 Subject The topic of the resource South America, Sudamérica, bosque templado, especie invasora, invasive species, mast seeding, mouse outbreak, ratada, semillación masiva, temperate forest Source A related resource from which the described resource is derived Revista Chilena de Historia Natural Publisher An entity responsible for making the resource available BMC Coverage The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant Botany, Zoology Relation A related resource <a href="http://www.scielo.cl/scielo.php?script=sci_arttext&amp;pid=S0716-078X2007000300004" target="_blank" rel="noreferrer noopener">http://www.scielo.cl/scielo.php?script=sci_arttext&amp;pid=S0716-078X2007000300004</a> https://socictopen.socict.org/files/original/6a5870df0b14449bef80d5d1e5224d58.pdf 50e14af60d83ddfc0d1317970b7487cb Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Title A name given to the resource Pinhão-Manso: Uma Alternativa para Produção de Biodiesel na Agricultura Familiar da Amazônia Brasileira. = Jatropha curcas: An alternative for biodiesel production in the Brazilian Amazonian family agriculture. Creator An entity primarily responsible for making the resource José Maria Arcanjo Alves, Ataiza de A. Sousa, Sebastião R. G. da Silva, Guido Nunes Lopes, Oscar José Smiderle, Sadra Cátia Pereira Uchôa Description An account of the resource O pinhão-manso (Jatropha curcas L.), da família Euforbiaceae, é uma espécie que pode ser cultivada em diferentes condições edafoclimáticas. Apresenta valor medicinal, ornamental e na produção de óleo. Atualmente tem aumentado o interesse no conhecimento agronômico desta cultura, visando à seleção e o aprimoramento de variedades mais produtivas e economicamente viáveis, principalmente devido ao alto potencial na produção de óleo para fabricar o biodiesel. Apesar de ainda não ser cultivada comercialmente no Brasil, mostra-se viável para a agricultura familiar das regiões Norte e Nordeste, pois tem alta resistência à seca e boa adaptação as altas temperaturas e insolação, além de produzir em solos ácidos e de baixa fertilidade como os do cerrado da Amazônia. Estudos estão sendo conduzidos com essa cultura no estado de Roraima visando desenvolver tecnologias viáveis de produção para serem adotadas pela agricultura familiar, como uma alternativa promissora na geração de emprego e renda, promovendo a recuperação e proteção de áreas alteradas ou degradadas e permitindo o consórcio com fruteiras nativas e culturas anuais. = The pinhão-manso (Jatropha curcas L.), from the Euforbiaceae famíly, is a species that can be raised in different edafoclimatic conditions. It presents a regular medicinal and ornamental value, and it is also useful for oil production, Nowadays it is increasing the interest in the agronomic knowledge of this culture, mostly related to the selection and improving of more productive and economically feasible varieties, mainly due to its high potencial for biodiesel production. Although this species is not yet cultivated for market use in Brasil, it has shown feasibility for family agriculture in North and Northeast regions, because of its great resistance to draught as well as its good adaptation to high temperatures and insolation. This species can also produce in highly acid and scarcely fertile soils, such as those in the Amazonian savannah. There are various studies in progress dedicated to this culture in Roraima state, and through these studies, it may be achieved a possibility to develop feasible production technologies that could be adopted by family agriculture. That would show a promising alternative for job creation and better income, fostering the recovering and protection of modified areas, and promoting the organization of native fruit and annual cultures consortiums.

Pérez Díaz, Ana Lucia Vásquez Vela, Agustín Cerna Mendoza, Manuel Santiago Doria Bolaños, Luís Arévalo López, João Luiz Lopes Monteiro Neto, Wilson F Guerra Arévalo, Sara Thiele Moreira Sobral, Carlos Abanto-Rodríguez Description An account of the resource La utilización de extractos vegetales como insecticidas naturales es una alternativa eficiente y ecológicamente viable para el uso directo en el control de plagas. En el estudio se evaluó el efecto de diferentes concentraciones de resina de Jatropha curcas en el control de larvas de Hypsipyla grandella Zéller, para el efecto en un Diseño Completamente al Azar (DCA), en esquema de parcelas subdivididas, se evaluaron cinco tratamientos, en tres repeticiones y 10 discos foliares de S. macrophylla por unidad experimental. Las parcelas principales consistieron en cinco concentraciones (%) de resina de J. curcas: T1:0; T2: 10; T3: 20; T4: 30; y T5: 40 y las subparcelas en los tiempos de evaluación (horas): 6, 12, 18 y 24 en el transcurso del día. Como variables medidas se incluyeron el consumo del disco foliares-CDF (%), el incremento de consumo foliar-ICF (%), la sobrevivencia-SL (%), la mortandad – ML (%), el número de orificios foliares-NOF y actividad larval-AL (%). La resina de J. curcas en concentración de 40% ocasiona en larvas de H. grandella una mortalidad de 67% y una actividad larval < 30%). Los resultados indican que las concentraciones de extracto de J. curcas ocasionaron efectos significativos en todas las variables evaluadas, no obstante, las concentraciones menores fueron menos eficientes en el control de larvas. Se concluye que la resina de J. curcas es un bioinsecticida potencial en el control de larvas de H. grandella presentando los mejores resultados en concentraciones > 30%.
