Description
An account of the resource
La industria de la construcción es una de las principales fuentes de contaminación en la actualidad, y por ello, las leyes destinadas a mitigar su impacto, resultan indispensables frente a problemas estructurales como el cambio climático. En esta investigación se analiza la construcción sostenible en Colombia y el Proyecto de Ley 208 2019 del Congreso de la República para su fomento. Se trata de un estudio cualitativo de tipo documental, enmarcado en el paradigma interpretativo. Se analizaron documentos publicados en los últimos cinco años que facilitaron el estudio del tema, así como la última iniciativa del legislativo colombiano para el fomento de la construcción sostenible. Los hallazgos del análisis evidencian, por un lado, una ausencia de estudios relacionados con el impacto de la industria de la construcción en el contexto colombiano, y por otro, una relación directa entre esta actividad económica, el desarrollo sostenible y el cambio climático. El frente legislativo es un escenario de acción para dar respuesta al complejo problema que se puede articular con la construcción sostenible. Se concluye, que en el país aún es incipiente el desarrollo normativo en la materia, y, por tanto, es necesario dar paso a una política pública de mayor alcance.

Description
An account of the resource
Em função de sua rusticidade, a cultivar IPR Cris é recomendada para sistemas de produção agroecológicos e para a agricultura familiar. Todavia, dada a aparência de seus tubérculos ovalados, gemas rasas e película não áspera, também pode ser utilizada em sistemas convencionais de plantio. 'IPR Cris' tem potencial de consumo para vários tipos de preparo, mas não para fritura industrial. Apresenta moderada resistência de campo para a requeima e não tem sido observada suscetibilidade à sarna comum; com potencial produtivo semelhante às cultivares atualmente em produção. Uma característica interessante que desponta na 'IPR Cris' é seu longo período de dormência, que por um lado desfavorece o plantio dos tubérculos semente na safra seguinte, por outro, garante ao pequeno produtor orgânico um período prolongado para comercialização, sem perda de qualidade dos tubérculos.

Description
An account of the resource
Resumo: Este trabalho tem como objetivo compreender os fatores que levam os jovens a optar por permanecer ou não nos empreendimentos de agricultura familiar localizados em Uberlândia-MG e Piracicaba-SP. A não permanência dos jovens no campo leva à ausência de sucessores, impactando na continuidade desses empreendimentos de agricultura familiar. Foi realizado um estudo de casos qualitativo e descritivo nos dois municípios. Os dados foram coletados por meio de entrevistas em profundidade, semiestruturadas, com proprietários e potenciais sucessores de estabelecimentos de agricultura familiar de Uberlândia e Piracicaba. A análise dos dados foi feita por meio da técnica de análise de conteúdo. As categorias utilizadas para a realização da análise foram: (1) história familiar; (2) estímulos/obstáculos à permanência no campo; e (3) perspectivas/alternativas/possibilidades. Os resultados apontam que existem fatores que tanto fortalecem quanto prejudicam a permanência dos jovens no meio rural. O vínculo familiar, as melhorias de condições de trabalho e de renda e a realização de uma gestão compartilhada entre pais e filhos servem de estímulo ao trabalho do jovem no campo. No entanto, a existência de conflitos, o processo sucessório tardio e sem planejamento e a falta de políticas públicas para o fortalecimento da agricultura familiar podem desestimular a permanência do jovem no meio rural.

Description
An account of the resource
Resumen: Los sistemas de extensión rural públicos juegan un rol central en la seguridad alimentaria, y más aún en un país como Guatemala, que cuenta con un 46,6% de niños menores de cinco años con desnutrición crónica. En este trabajo se exponen los resultados de un estudio orientado a comprender los problemas que limitan los resultados y el impacto del servicio de extensión del Ministerio de Agricultura, Ganadería y Alimentación (Maga) en el oriente del país. Se realizaron 12 entrevistas individuales y 4 grupos focales con extensionistas de la institución en los departamentos de Chiquimula y Zacapa, las cuales fueron analizadas a partir de un proceso de codificación realizado con el apoyo del software Atlas Ti. La muestra y los departamentos fueron seleccionados por razones de accesibilidad y conveniencia. Se concluye que el entorno de politización y corrupción política tiene un papel estructurante en la dinámica del servicio de extensión del Maga, que el sistema de extensión del Maga es sumamente débil a nivel institucional, que existen problemas significativos relacionados con los recursos humanos, y que las prácticas de extensión tienen impacto limitado. Se recomienda generar acciones para fortalecer el sistema de extensión del Maga y diseñar estrategias creativas para formar extensionistas.

Resumen Este ensayo académico pretende articular epistemológicamente el conocimiento indígena y el discurso ético-político de la salud colectiva a través de la propuesta de la ecología de saberes de Boaventura de Souza Santos. Indudablemente la incursión del conocimiento indígena en las universidades como una nueva agenda académica, requiere que en salud se profundice en el dialogo entre el saber popular y el conocimiento científico. Esta discusión plantea un reto para la salud colectiva desde la justicia cognitiva, la decolonialidad y el conocimiento situado.

Resumen: Mostramos la importancia de los canales alternativos de comercialización del sector de la Agricultura Familiar como herramienta para el desarrollo rural, relevando una experiencia de comercialización alternativa para productores familiares de La Matanza, provincia de Buenos Aires, Argentina: la “Feria del Productor al Consumidor: la soberanía alimentaria entra a las aulas”, en la Universidad Nacional de La Matanza. Aplicamos metodología cualitativa con trabajo de campo etnográfico (entrevistas a feriantes, extensionistas, visitantes y consumidores, y observaciones realizadas durante ediciones de la feria y reuniones de la asamblea de feriantes). También utilizamos datos secundarios de fuentes bibliográficas y estadísticas nacionales sobre agricultura familiar y ferias en Argentina. Debatimos sobre desarrollo rural en Argentina y las funciones estratégicas de la comercialización en la AF. Describimos la situación de las ferias de la AF en Argentina y analizamos la experiencia presentada. Concluimos que este sector productivo, a pesar de su relativa informalidad, debe ser considerado por su aporte económico al desarrollo nacional y su rol fundamental de proveedor de alimentos al mercado interno. Estos agricultores requieren políticas diferenciales que consideren sus particulares características. Por otra parte, reconocemos que estas ferias contribuyen al desarrollo rural como potente instrumento de comercialización alternativa para el sector, mejoran intercambios entre actores, reflejado en el incremento del capital social.

Description
An account of the resource
Foram avaliados durante três anos os efeitos de tratamentos de fogo e pastejo sobre a dinâmica da vegetação de uma pastagem natural localizada em Santa Maria, na região da Depressão Central, Rio Grande do Sul. Foi considerada a hipótese de resiliência, resultado das espécies componentes da pastagem terem evoluído sob influência de tais distúrbios. O experimento foi composto por oito parcelas experimentais submetidas a combinações de níveis de pastejo (pastejado, excluído) e de fogo (queimado, não-queimado), em duas posições de relevo (encosta, baixada). A análise multivariada dos dados de composição de espécies foi baseada em ordenação e testes de aleatorização. A vegetação sob efeito de pastejo, independente da queima, apresentou trajetórias direcionais, enquanto sob exclusão as trajetórias foram caóticas. O efeito do pastejo parece ser determinante da dinâmica vegetacional (P=0,077).

Resumo: A agricultura biológica cria um mercado para bens e serviços ambientais, e os produtores podem ser recompensados pela sua gestão agroambiental através de preços premium e pela Política Agrícola Comum (PAC). O objetivo deste trabalho foi caracterizar os agricultores da Região Centro de agricultura do ponto de vista socioeconómico, além de avaliar a propensão para a mudança do modo produtivo para a agricultura biológica e identificar as principais dificuldades para a mudança. Foi realizado o estudo dos efeitos das políticas agrícolas na evolução da agricultura biológica. Foram realizados estudos através de entrevistas presenciais resultando em dois estudos de caso. Os estudos de caso apresentam metodologias distintas, mas complementares. O trabalho revelou que a PAC contribuiu para o desenvolvimento deste setor e os dados alcançados permitem aos investigadores desenvolver técnicas para que os agricultores possam superar os obstáculos e aumentar a competitividade da cadeia de valor. A renovação geracional e o aumento da dimensão da exploração são factores a considerar para o progresso da agricultura biológica. É necessário gerar formação adequada às necessidades e fornecer informações precisas e reais sobre as dificuldades e benefícios desse modo de agricultura.

Description
An account of the resource
A study on the spatial distribution of the major weeds in maize was carried out in 2007 and 2008 in a field located in Golegã (Ribatejo region, Portugal). The geo-referenced sampling focused on 150 points of a 10 x 10 m mesh covering an area of 1.5 ha, before herbicide application and before harvest. In the first year, 40 species (21 botanical families) were identified at seedling stage and only 22 during the last observation. The difference in species richness can be attributed to maize monoculture favouring reduction in species number. Three of the most representative species were selected for the spatial distribution analysis: Solanum nigrum, Chenopodium album and Echinochloa crus-galli. The three species showed an aggregated spatial pattern and spatial stability over both years, although the herbicide effect is evident in the distribution of some of them in the space. These results could be taken into account when planning site-specific treatments in maize.

Old grapevine (Vitis vinifera L.) accessions are a source of genes that could be rescued for use per se or in modern breeding programs. The first step in this rescuing is collecting and characterizing the germplasm from a particular region. This study presents the genetic characterization of 21 grapevine accessions collected from the Atacama Desert in the far North of Chile. Characterization was based on 12 microsatellites (Simple Sequence Repeats, or SSRs) supplemented with Amplified Fragment Length Polymorphic (AFLP) markers. Most of the collected accessions produced red berries and shared the genetic characteristics of the cv. País, an old genotype found throughout America. However, among those red-berried accessions, one showed a severe abortive phenotype (22S7), and another (6S4) differed from ‘País’ in one allele. Both could be examples of somatic mutations, even though no variations in their AFLP patterns were found. On the other hand, the only accession with red berries that exhibited genetic characteristics different from those of ‘País’ (5CN) corresponded to ‘Gros Colman’, a supposedly Georgian genotype introduced to this region by the mid-20th century. Greater genetic diversity was detected among the white and pink accessions, which were classified into five clades based on their SSR allelic patterns. Of these genotypes, 11Si was identified as ‘Emperatriz’ or ‘Red Seedless’, an Argentinean variety; accessions 16H1 and 17H2 corresponded to a product of crossing ‘País’ and ‘Muscat of Alexandria’; and, finally, accession 20S5 was identified as ‘Ahmeur bou Ahmeur’, an Algerian genotype harboring pink berries. Two seeded genotypes harboring small and large white berries were not identified as known varieties. The possible use of these accessions for breeding to enhance survival in the harsh environment of the Atacama Desert is discussed.Las accesiones de vid (Vitis vinifera L.) de antigua data son una fuente de variantes génicas que pueden ser rescatadas para su uso directo o su incorporación en programas de fitomejoramiento. La primera etapa de este rescate es la colecta y caracterización del germoplasma propio de una región particular. Este estudio describe la caracterización genética de 21 accesiones de vid colectadas en el desierto de Atacama, en el Norte de Chile. La caracterización se basó en 12 marcadores de microsatélites (SSR), complementado con marcadores de tipo fragmentos amplificados de largo variable (AFLP). La mayoría de las accesiones colectadas con bayas negras corresponden al genotipo ‘País’, un cultivar antiguo que se encuentra distribuido en toda América. Sin embargo, entre las accesiones de baya negra, una de ellas mostró un fenotipo abortivo severo (22S7), y otro (6S4) difirió en un alelo con respecto a ‘País’. Ambos podrían ser ejemplos de mutaciones somáticas, aun cuando no fue posible detectar variaciones en sus patrones de AFLP. Por otra parte, la única accesión con bayas negras que exhibió características genéticas diferentes a ‘País’ correspondió a ‘Gros Colman’ (5CN), un genotipo supuestamente proveniente de Georgia, Rusia, introducido en esta región a mediados del siglo XX. Una mayor diversidad genética fue detectada entre las accesiones de bayas blancas y rosadas, que se clasificaron en cinco clados en base a sus alelos de microsatélites. De estos genotipos, 11Si se identificó como ‘Emperatriz’ o ‘Red Seedless’, una variedad de origen argentino, mientras que las accesiones 16H1 y 17H2 correspondieron a un cruzamiento de ‘Moscatel de Alejandría’ × ‘País’. Por último, la accesión 20S5 se identificó como ‘Ahmeur bou Ahmeur’, un genotipo argelino de bayas de color rosado. Dos genotipos semillados de bayas blancas, pequeñas o grandes, no se asimilaron con alguna variedad conocida. Se discute también la posibilidad de utilizar algunas de estas accesiones en fitomejoramiento, para aumentar la tolerancia a estreses propios del ambiente del desierto de Atacama.
