Introducción: La ganadería es el sector económico de mayor importancia en el departamento del Caquetá, muchas de las familias rurales dependen de dicha actividad; para ello, la metodología de análisis de vida examina los activos con los que cuentan las comunidades, denominados capitales de la comunidad y el enfoque que usan para suplir sus necesidades humanas fundamentales, las cuales están directamente relacionadas con el entorno y con la capacidad asumida por las familias para poder tener una mayor calidad de vida. Objetivo: Evaluar los medios de sostenibles y la aplicación de los capitales de la comunidad en familias ganaderas del municipio de El Doncello, Caquetá (Colombia). Materiales y métodos: para la recolección de la información se evaluó las familias productoras del municipio de El Doncello (Caquetá); tomando como base las fuentes del Comité Departamental de Ganaderos; para ello, se encuestaron las familias y se hicieron talleres participativos usando la metodología de medios de vida, enmarcando los capitales de la comunidad (humano, natural, financiero, físico y social) y las necesidades humanas fundamentales (básicas, de la persona, del entorno y de acción). Resultados: Se observó que 939 familias dependen económicamente de esta actividad en el municipio, y se encontró tres tipologías de familias: Tipología 1: familias con 101 bovinos, donde el capital financiero es uno de los que mayor aporte presenta dado sus características de generación de ingreso y bienestar a las familias. Las necesidades humanas no están ligadas totalmente a cada una de las tipologías encontradas, sino a sus satisfactores. Conclusiones: Finalmente, este estudio repercute como un primer diagnóstico productivo y de aplicación de medios de vida rurales a comunidades productoras del municipio de El Doncello, que puede servir como base metodológica para futuras investigaciones en el campo.

Through the signing of the peace treaties between the Colombian government and theFARC-EP (Revolutionary Armed Forces of Colombia), the former territorial spaces fortraining and reintegration –AETCR– were created for former combatants. This work aimsto analyze the life strategies of the community of ex-combatants of the “Héctor Ramírez”Population Center Agua Bonita, La Montañita-Caquetá, Colombia, using the livelihoodsmethodology and, from this, to characterize the seven capitals of the community. (human,social, natural, financial, political, cultural and physical). This made it possible to identifylife strategies and generate a quality of life index, obtaining information through surveys,interviews and direct observation of said population. It was found that the AETCR, todaycalled the Populated Center, presents great capacities to adapt to the roots of the ruralcommunities of the municipality, showing great advances in terms of social reconciliation,reintegration into civil life and contributions in cultural issues to the surrounding communities.The main conclusion is that this community of ex-combatants has been adaptingvery well to the needs of the environment and to the good social relationship with thecommunities, which demonstrates their great interest in the reincorporation process andtheir re-socialization to civil life.

Se evaluaron los parámetros hematológicos en la especie Oreochromis niloticus, con peso entre los 120 y 375 g, donde se incluyeron estándares químicos del agua (T°, pH y OD), la morfometría y el diagnóstico hematológico, realizados en la Granja Experimental Santo Domingo de la Universidad de la Amazonia, Florencia- Caquetá-Colombia. Se utilizó un muestreo dirigido y completamente al azar de 32 individuos, la sangre fue extraída por punción cardiaca y colocada en tubos Eppendorf con EDTA. Los frotis sanguíneos se tiñeron con coloración Ema color tinción para su análisis en laboratorio. Se aplicó el InfoStat como método estadístico para el análisis de las variables a medir. Se encontró un total de leucocitos de 1,11 celx105 /mm3 , predominando los neutrófilos con 49,3% seguido de linfocitos con 38,8%, monocitos con 5,9%, eosinófilos con 4,3%, basófilos con 1,7 % y trombocitos con 63,8 % como serie independiente. Para la serie roja se encontró un promedio de eritrocitos de 1,5 celx106 /mm3 , hemoglobina de 7.9 g/dL; hematocrito de 23.3%, proteínas plasmáticas 3,3 g/dL, volumen corpuscular medio 165 (u3 ), hemoglobina corpuscular media 55 (uug) y concentración de hemoglobina corpuscular media de 33.3%. Como conclusión se determinó que algunos individuos presentaron Leucopenia con Linfopenia y trombocitosis. Además, dos individuos presentaron Anemia Microcítica Normocrómica (AMN) y 19 individuos presentaron Anemia Normocitica Normocrómica (ANN). El análisis de Proteínas Totales del Plasma (PPT) determinó que la alta tasa de mortalidad no fue por deficiencia nutricional. Se presentó una similitud positiva entre el VCM y HCM, y de forma negativa con el número total de eritrocitos.

This paper analyzed the importance of productive projects in the reintegration process of ex-combatants of the Revolutionary Armed Forces of Colombia (FARC), in the rural settlement “Héctor Ramírez” located in Caquetá, after the signing of the Colombian peace process in 2017. In this regard, the research was characterized by being a descriptive study as a qualitative approach, using the semi-structured interview as a data collection instrument applied to ex-combatants to recognize their expectations about the productive projects that they have been developing in the camp. It was found that ex-combatants reinvest the earnings received in productive projects to achieve, under their criteria, possibilities of growth and financial return for the long term. In addition, they hope that the Colombian government will support the improvement of the commercialization processes of the products generated in the different projects. In this way, the standards of well-being at the personal and community level will be improved.

Cocoa (Theobroma cacao L.) is one of the main species of the peasant agroforestry system in many regions of Colombia and is considered one of the crops with the greatest economic projection, given its industrial demand and food importance. Production yields in the country are limited by various factors, with fungal diseases being a major challenge. Consequently, there is a strong need to develop safe and effective phytosanitary solutions to manage these diseases, reduce losses, and enhance productivity. The objective of the present study was to evaluate the antifungal potential of 4 concentrations (500, 1000, 2000 and 5000 ppm) of root, leaf and stem extracts of the Piper peltatum plant for the control of the fungus Moniliophthora roreri. For this, the fungus was collected and isolated from cocoa pods (T. cacao) and morphologically characterized. The results allowed to determine that P. peltatum in root extracts presents total phenol values ​​of 63 mg A.G g-1 and flavonoids of 74.88 mg CAT/g-1 and antioxidant activity greater than 200 mg Tx/g-1, ABTS. with values ​​of 300 mg Tx/g-1 and FRAP greater than 100 mg AA/g-1. Finally, the concentrations of Piper peltatum extracts showed an inhibition of mycelial growth greater than 88% in all concentrations and plant organs evaluated, highlighting the high potential of Piper peltatum as a controlling agent of Moniliophthora roreri in Cocoa crops in the Colombian Amazon region.

South American Leaf Blight (SALB) is the primary limitation to the establishment of new rubber (Hevea brasiliensis) crops in Latin America. This study aimed to assess the temporal dynamics of resistance to SALB in 99 elite Colombian genotypes and the IAN 873 cultivar (control) of H. brasiliensis in small-scale clone trials conducted under conditions with a high disease prevalence in the northwestern Colombian Amazon. Resistance monitoring was carried out on a monthly basis and analyzed over five climatic periods. Three variables were recorded: attack severity (AT, ranging from 0 to 4), reaction type (TR, ranging from 1 to 6) and stromal density (ST, ranging from 0 to 4). The maximum scores for TR and ST were used to classify the level of resistance of the genotypes. Highly significant differences in the mean values of AT, TR and ST among the genotypes, across the periods, and in the interaction between genotype and period were found. Over time, an increase in symptoms (AT) and signs (TR and ST) of SALB was observed. During the rainy periods, SALB intensity was highest, resulting in a leaf area affected ranging from 16 to 30%. Eight genotypes showed partial resistance (PR) (TR < 5 and ST < 2), while 16 genotypes demonstrated complete resistance (CR) (TR < 3 and ST = 0), and 76 genotypes were highly susceptible (HS) (TR > 5 or ST > 2). The temporal analysis identified 23 Colombian superior genotypes with varying degrees of SALB resistance, which can be a valuable breeding resource for improving SALB management in the Colombian Amazon region.
