Contextualization: Life Cycle Assessment [LCA] is a useful tool for assessing the potential environmental impacts of a product. Due to the growing interest in climate change mitigation and on the implementation of sustainable practices of production, it is interesting to study the environmental profile of essential oil products and similar products to identify shortcomings in current technologies and possibilities for ...

Results and conclusions: The area has two types of vegetation cover, three hydrological soil groups and an average NC of 59.29, demonstrating a moderately high runoff potential and a moderate infiltration capacity; the available annual water supply was 42573.6 m3. The behavior of water availability depends on anthropic activities inside and outside the wetland as well as on the precipitation regime.

Contextualization: The floristic analysis of the components associated with the cocoa crop is considered as a keystone to design relevant agroforestry models. Knowledge gap: In the Pacific Coast of Nariño, traditional agroforestry systems of cocoa have a diversity of secondary species; however, there are few studies that have identified and characterized their economic and environmental benefits.  Purpose: The objective ...

ABSTRACT   Contextualization: Invasive plants such as the thorny broom (Ulex europaeus), negatively impact biodiversity and the normal development of ecosystems in the territories where it is present. Likewise, there are effects on agricultural fields, reducing the area to be cultivated, which has repercussions on the decrease in harvests. Knowledge gap: Reason why, it is pertinent to develop low-cost and effective ...

Contextualization: For more than a century, coffee has been the main product of the national economy, also the one that has had the greatest incidence in the socioeconomic development of Colombia; for this reason, it is relevant to check up the biotic and abiotic factors that affect coffee production, especially in the department of Norte de Santander. The coffee-growing zone of the department is located between 6º56'42" ...

Contextualization: the poultry red mite (Dermanyssus gallinae) is an ectoparasite that affects the health     , generates stress in the population, and decreases the growth rate of laying hens.      Therefore, lowers the quality of the eggs.  Knowledge gap: the control of D. gallinae is done with synthetic contact acaricides, but this parasite has generated resistance to them. That situation requires the development ...

Contextualization: Solid ruminal activators (SRA) that improve fermentation conditions in the rumen microorganisms of the cattle, used as feed additives, have gained importance in the nurturing of ruminants. They promote animal production rates and replace growth promoters, such as antibiotics, that can affect animal production and influence on their consumers microbiota; consequently, they can strongly affect human ...

La palabra Métodoestesis (Los caminos del sentir) creada por Ana Patricia Noguera, nombra las trayectorias epistémicas que se describen en este artículo. La primera es la propuesta Ecosistema – Cultura, elaborada por Augusto Ángel-Maya, uno de los creadores del Pensamiento Ambiental Latinoamericano. En ella, Augusto de apartó del modelo de Desarrollo Sostenible, para pensar lo ambiental como lo emergente de las ...

Los contaminantes emergentes constituyen un grupo de sustancias cuya regulación está siendo abordada, debido al incremento de su presencia en cuerpos de agua asociado principalmente a las acciones antropogénicas. Estos compuestos caracterizados como disruptores endocrinos a bajas concentraciones causan daños irreversibles en los ecosistemas y están siendo objeto de estudio especialmente en las últimas dos décadas. Para ...

El desarrollo económico descontrolado y la sobreexplotación de los recursos naturales han aumentado los niveles de contaminación sobre el recurso hídrico a pesar que existen diferentes tecnologías para el tratamiento de residuos líquidos, uno de los más utilizados es el tratamiento primario avanzado, el cual consiste en la coagulación/floculación y sedimentación de materiales particulados presentes en el agua. Este ...
