Asegurar un nivel adecuado de salubridad en las personas constituye, para los gobiernos locales, uno de los retos más grandes de afrontar. Uno de estos retos lo constituye una gestión adecuada de la creciente generación de residuos sólidos urbanos, que vienen causando efectos nocivos, algunas veces irreversibles, en los recursos agua, aire y suelo y que además ponen en riesgo la salud e integridad de las personas; esto exige desarrollar e implementar propuestas que aborden el problema de manera integral, desde un enfoque que incorpore la participación de la comunidad, el gobierno y las instituciones locales así como de la aportación del sector privado. Específicamente en la ciudad de Jaén, la generación de residuos, así como su inadecuada recogida, tratamiento y disposición final, han dado como resultado un incremento en los niveles de contaminación, sumado al incumplimient...

Non-destructive methods that accurately estimate leaf area (LA) and leaf weight (LW) are simple and inexpensive, and represent powerful tools in the development of physiological and agronomic research. The objective of this research is to generate mathematical models for estimating the LA and LW of Cinchona officinalis leaves. A total of 220 leaves were collected from C. officinalis plants 10 months after transplantation. Each leaf was measured for length, width, weight, and leaf area. Data for 80% of leaves were used to form the training set, and data for the remaining 20% were used as the validation set. The training set was used for model fit and choice, whereas the validation set al.lowed assessment of the of the model’s predictive ability. The LA and LW were modeled using seven linear regression models based on the length (L) and width (Wi) of leaves. In addition, the models wer...

El árbol de la quina, es un término comúnmente conocido para todas las especies del Género Cinchona. Pese a que representa la riqueza vegetal del Perú, y está plasmada en el escudo nacional, actualmente varias especies de este género, están en peligro de extinción, por lo que alberga una alta importancia ecológica, social, económica y ambiental para nuestro país. Históricamente, la gama natural de Cinchona se registró desde sus inicios como extensa. Las primeras referencias registradas en textos, coinciden la presencia de Cinchona en Sudamérica, dentro del área del llamado “eje de la salud” en el mapa del mundo andino; resaltando su importancia al representar la región como el centro de curación de la antigua área cultural andina central que se extendía desde Ecuador hasta Bolivia. En ese sentido, el Perú realizó esfuerzos para conservar el árbol de la quina, y...

El árbol de la quina o cascarilla (Cinchona spp., Rubiaceae) es un grupo de especies dentro de la familia del café. Este grupo es originario de los Andes, los pueblos indígenas y locales usan la corteza, abundante en quinina, principalmente para fines medicinales para mejorar las fiebres. Con la invasión europea, este género jugó un papel importante social y económico para el desarrollo de los imperios europeos permitiéndoles colonizar regiones tropicales plagadas con malaria. A finales del siglo XIX, el primer cartel farmacéutico se estableció para mantener el monopolio de comercialización de quinina por empresarios de Alemania. Luego el cartel pasó a manos de compañías de los Países Bajos que fue el primer caso de colonización corporativa de la salud pública por una empresa privada. A pesar de la gran importancia biocultural para nuestros pueblos, y económica y farmac...

Hemileia vastatrix is a fungus that causes coffee rust disease and, depending on the level of severity, reduces the photosynthetic capacity of the plant and of new shoots, leading to low coffee yields and even death; its symptoms are visible on the leaf. Systems based on computer algorithms have been developed to predict diseases and pests in coffee. The objective of the manuscript was to analyse the detection of rust occurrence in coffee plantations, through field determinations of climatological, agronomic and crop management variables using data mining algorithms. A systematic review of studies published from 2001 to 2021 was carried out in the Scopus, Ebsco Host and Scielo databases, considering as an inclusion criterion the works that used experimental design in data collection. The studies included in this review were 22, 64% of which came from the top two coffee-roducing countries...

Cinchona officinalis, a native plant species known in Peru as the cinchona tree, has civic importance because it represents the plant wealth of this nation and medicinal importance since it was for more than 300 years the only cure for malaria, and is currently threatened. The aim was to determine the effect of light conditions on the percentage of mortality, height increase, and diameter increase of Cinchona officinalis. In the community of La Cascarilla (5°39’48.87 “S 78°54’35.24 “W), two treatments were installed, forest massif (FM) and enrichment bands (EB). For each treatment, three replicates and 16 plants per replicate were used. Monthly evaluations were carried out in which the number of dead plants, plant height, and diameter were recorded. These parameters were correlated with precipitation, temperature, and photoperiod records of the study area. The results showed th...
