Title A name given to the resource Discussions around public policies for food sovereignty and family farming in Misiones (Argentina) Creator An entity primarily responsible for making the resource Mariana Beatriz Arzeno, Rocío del Pilar Deheza, Lucila Muñecas, Aymara Suyai Zanotti Description An account of the resource The aim of this paper is to analyze the policies for food sovereignty in Misiones and its relation to the demands of family farmer’s organizations, taking into account different views on the subject of the actors involved and the actions that are routed from different levels of government. The research is based on primary and secondary information. This analysis reveals divergences between the idea of food sovereignty of provincial government (replacing food imports) and national government (democratization of access) that support intervention strategies to some extent contradictory and distanced from the demands of family farmer’s organizations (centered on the land, to produce food).

Title A name given to the resource Young farmers and generational reproduction in family farming: a case study of young people residing in the municipality of Faxinal Soturno - Brazil Creator An entity primarily responsible for making the resource Lucas Coradini Description An account of the resource This study examines how the youth’s Professional projects in new generation of family farmers are prepared and the perspective of reproduction of the familiar mode of production. The sociological task is to specify the distinctive features of the situation of the youth in family farming, seeking to identify the elements considered in the preparation of their professional projects. Qualitative data were produced by a case study of young farmers who lives in the city of Faxinal do Soturno, a municipality belonging to the fourth colony of Italian immigration in Rio Grande do Sul/Brazil. We performed 36 interviews, consisting of open questions, adopting a semi-structured script, wich were examined by de method of content analysis. Among the results, were observed a context marked by professional projects that breaks with the succession of the family farm work. The negative ratings on agricultural work stand out, particularly on issues related to health, salubrity of work and conditions of aging in rural areas. Family and emotional issues, and also specific aspects of the juvenile condition, marked by the pursuit of autonomy and emancipation, permeate the professional projects in development and show a complex analytical framework, wich amplify the explanatory factors of migration of youth.

Su funcionamiento genera residuos que dada su composición y posibilidad de procesamiento, se convierte en un material de interés para ser aprovechado como materia prima en la elaboración de bioplásticos. La disponibilidad del residuo depende del volumen generado, razón por la cual se estimó la cantidad que produce la agroindustria del país, usando una metodología preestablecida que parte del promedio anual de cultivos, la porción de producción asignada al procesamiento industrial, la tasa de generación de residuos y otros usos competitivos. Se estimó que anualmente la agroindustria del país genera cerca de 2200 millones de kilogramos, los cuales en su mayoría están compuestos por almidón o recursos lignocelulosos, que con transformaciones físicas, químicas o biotecnológicas, pueden emplearse como materia prima, material de relleno o precursor de los bioplásticos.

Title A name given to the resource Incidência de pragas e doenças em agroecossistemas de café orgânico de agricultores familiares em Poço Fundo-MG Incidence of plagues and diseases in agroecossystems of organic coffee of familiar farmers in Poço Fundo-MG Creator An entity primarily responsible for making the resource Márcia Martins, Antônio Nazareno Guimarães Mendes, Maria Inês Nogueira Alvarenga Description An account of the resource Objetivando-se determinar a incidência de pragas Leucoptera coffeella (GUÉRIN-MENÉVILLE, 1842) e Hypothenemus hampei (FERRARI, 1867) e doenças Hemileia vastatrix (BERK e BROOME, 1869) e Cercospora coffeicola (BERK e CURTIS, 1880), durante o período de janeiro de 2001 a dezembro de 2002, foram selecionados três agroecossistemas com produção de café orgânico conduzidos por agricultores familiares do município de Poço Fundo-MG. O agroecossistema I possui 2.200 pés da cultivar 'Catuaí Vermelho' em espaçamento 2,5 x 1,3 m (0,72 ha). O agroecossistema II possui 2.000 pés ('Catuaí Vermelho') em espaçamento 2,8 x 1,0 m (0,56 ha). O agroecossistema III possui 1.100 pés ('Icatu Amarelo') em espaçamento 3,0 x 0,9 m (0,36 ha). A determinação da incidência de L. coffeella, C. coffeicola e H. vastatrix foi realizada mediante levantamentos mensais. A determinação da infecção por C. coffeicola em frutos foi realizada nos meses de abril, maio e junho de 2001 e 2002. O levantamento da infestação por H. hampei foi realizado nos meses de janeiro a junho/julho de cada ano. Determinou-se que a infestação por L. coffeella ultrapassou 20% no terço superior (principalmente no período seco). A infestação por H. hampei atingiu o nível de dano somente no agroecossistema I, em 2001, e no agroecossistema III, em 2002. A infecção por H. vastatrix no agroecossistema III não atingiu nível de dano em conseqüência da tolerância da cultivar ('Icatu') à infecção por esse fungo; porém, nos agroecossistemas I e II ('Catuaí Vermelho'), a infecção na lavoura ultrapassou o nível de 10% (principalmente no período seco). A infecção por C. coffeicola em folhas e frutos atingiu níveis elevados (período seco). A produtividade do agroecossistema I, em 2001, foi de 510 Kg ha-1 e, em 2002, de 2.340 Kg ha-1; no agroecossistema II, em 2001, foi de 420 Kg ha-1 e, em 2002, de 1.290 Kg ha-1; e, no agroecossistema III, foi praticamente zero, em 2001, e em 2002, de 2.010 Kg ha-1.Having as an aim the determination of insect plagues, Leucoptera coffeella (GUÉRIN-MENÉVILLE, 1842) and Hypothenemus hampei (FERRARI, 1867) and diseases incidence Hemileia vastatrix (BERK e BROOME, 1869) and Cercospora coffeicola (BERK e CURTIS, 1880) during the period from January of 2001 to December of 2002, three agroecosystems with production of organic coffee conducted by familiar farmers of the city of Poço Fundo-MG were selected. The agroecosystem I possesses 2.200 plants of the cultivar 'Red Catuai' spaced 2,5 x 1,3 m (0,72 ha). The agroecosystem II has 2.000 plants ('Red Catuai') spaced 2,8 x 1,0 m (0,56 ha). The agroecosystem III possesses 1.100 feet ('Yellow Icatu') spaced 3,0 x 0,9 m (0,36 ha). The determination of the incidence of L. coffeella, C. coffeicola and H. vastatrix was accomplished starting from monthly surveys. The determination of the infection for C. coffeicola in fruits was accomplished in the months of April, May and June of 2001 and 2002. The survey of the infestation by H. hampei was accomplished from January to June/July of each year. It was determined that the infestation by L. coffeella has reached over 20% in the upper third (mainly during the dry period). The infestation by H. hampei has reached the damage level only in the agroecosystem I on 2001 and agroecosystem III on 2002. The infection by H. vastatrix in the agroecosystem III did not reach the damage level due to the tolerance of the cultivar ('Yellow Icatu') to the infection by this fungus, however, the agroecosystem I and II ('Red Catuai') the infection in the field exceeded 10% (dry period). The infection by C. coffeicola in leaves and fruits reached high levels (dry period). The productivity of the agroecosystem I was 510 Kg ha-1 on 2001 and 2.340 Kg ha-1 on 2002, in the agroecosystem II, it was 420 Kg ha-1 on 2001 and 1.290 Kg ha-1 on 2002, and in the agroecosystem III, it was practically zero on 2001 and 2.010 Kg ha-1 on 2002.

En particular, los géneros Azotobacter y Azospirillum son utilizados como agentes promotores de crecimiento vegetal debido a su capacidad para fijar nitrógeno atmosférico y producir hormonas de tipo indólico. Por tal razón, en este estudio se aislaron bacterias diazotróficas de los géneros Azotobacter y Azospirillum a partir de la rizósfera de cultivos de algodón en el Espinal (Tolima). Las poblaciones microbianas se caracterizaron fenotípicamente en los medios de cultivo semiespecíficos: Ashby y LG (Azotobacter sp.) y NFb, LGI y Batata (Azospirillum sp.). La promoción de crecimiento vegetal se determinó mediante la actividad de la enzima nitrogenasa por medio de la técnica de reducción de acetileno y producción de índoles por el método colorimétrico de Salkowsky. Se obtuvieron 9 aislamientos tentativos de Azotobacter sp. y 4 de Azospirillum sp. Se presentaron diferencias significativas en la prueba de reducción de acetileno con las cepas presuntivas de Azotobacter sp.: NAT 9 (206.43 nmol C2H2 mL-1.h-1), NAT 4, (292.77 nmol C2H2 mL-1.h-1), y NAT 6 (460.60 nmol C2H2 mL-1.h-1) y en la producción de índoles de las cepas NAT 19 (19.87 μg.mL-1) y NAT 13 (20.08 μg.mL-1). Por su eficiencia in vitro en la promoción de crecimiento vegetal se seleccionaron las cepas NAT9, NAT4, NAT6, NAT19 y NAT13 para ser evaluadas como principio activo en futuros inoculantes para el algodón en esta zona del departamento del Tolima. Palabras clave: fijación biológica de nitrógeno; producción de índoles; promoción del crecimiento vegetal;  biofertilizantes. Abstract: As part of strategies for sustainable agriculture, it is necessary to reduce the use of synthetic nitrogen fertilisers through the use of biofertilisers. In particular, the genera Azotobacter and Azospirillum are used as plant growth promoters because of their ability to fix atmospheric nitrogen and indolic type hormones. For this reason, in this study were isolated diazotrophic bacteria of the genera Azotobacter and Azospirillum from the rhizosphere of cotton crops in Espinal (Tolima). The microbial populations were characterized phenotypically in specific semi culture media: Ashby and LG (Azotobacter sp.) and NFb, LGI and Batata (Azospirillum sp.). The promotion of plant growth was determined by the enzyme nitrogenase activity through acetylene reduction technique and production of indoles by the salkowsky colorimetric method. 9 isolates were obtained tentative Azotobacter sp. and 4 of Azospirillum sp. Significant differences in acetylene reduction test with presumptive strains of Azotobacter sp.: NAT 9 (206.43 nmol C2H2 mL-1.h-1), NAT, 4, (292.77 nmol C2H2 mL-1.h-1), and NAT 6 (460.60 nmol C2H2 mL-1.h-1) and indole production strains NAT 19 (19.87 μg.mL-1) and NAT 13 (20.08 μg.mL-1). In vitro efficiency in promoting plant growth were selected strains NAT9, NAT4, NAT6, NAT19 and NAT13 to be evaluated as active in future inoculants on cotton in this part of the department of Tolima.

Title A name given to the resource Eficiencia técnica en la agricultura familiar: Análisis envolvente de datos (DEA) versus a proximación de fronteras estocásticas (SFA) Creator An entity primarily responsible for making the resource Ramiro Rodríguez Sperat, María Pía Brugiafreddo, Erica Raña Description An account of the resource El presente trabajo estudia la eficiencia técnica en la agricultura familiar, tomando como caso de estudio las explotaciones que producen leche de cabra en la cuenca lechera caprina de Santiago del Estero, y utilizando el Análisis Envolvente de Datos (DEA) y la Aproximación de Fronteras Estocásticas (SFA). En relación a la eficiencia de los productores estudiados, se observa que la cuenca lechera caprina de Santiago del Estero cuenta con índices de eficiencia técnica promedio de 0.567 (utilizando DEA CRS), 0.693 (utilizando DEA VRS) y 0.745 (utilizando SFA). Mediante la comparación de los resultados se observa que no existirían diferencias en los resultados entre DEA (VRS) y SFA, en cambio si se observan diferencias al comparar los resultados de DEA (CRS) y SFA. En ese marco, no se encontraron fundamentos para utilizar uno u otro método para los estudios de eficiencia en la agricultura familiar, debiéndose tomar la decisión de que método utilizar para cada caso en particular, de acuerdo al tipo de información disponible, la formación de cada investigador y la aplicación que se busque dar a los resultados.
