Recordar también es innovar: Agroecología para la resiliencia alimentaria en Paine, Región Metropolitana, Chile
(Universidad de Chile, 2023)
La triple crisis (climática, pérdida de biodiversidad y contaminación) genera impactos en los sistemas socioecológicos. Los sistemas agroalimentarios convencionales son altamente vulnerables, sin embargo la agroecología demuestra tener alta...
Desafíos locales para la agroecología : un análisis espacial para la recuperación de recursos en la Provincia de Quillota, Chile
(Universidad de Chile, 2021)
modelos productivos más sustentables como el que demuestra la Agroecología, consideramos importante analizar cómo se están gestionando los residuos orgánicos de este sector. Para esto, el estudio de diversos actores: públicos, privados y predios agrícolas...
The management of organic waste from the agricultural sector in Chile still has little study and analysis considering the expansion of monoculture and linear and intensive production of the agricultural sector in recent decades. In order to move to more sustainable production models such as the one demonstrated by Agroecology, we consider it important to analyze how organic waste in this sector is being managed. For this, the study of various actors: public, private and agricultural properties of different scales and a spatial analysis of the province of Quillota in the Valparaíso region, allowed to identify the current management of organic matter in the territory, and to recognize the main barriers for materializing waste management based on a circular economy in the agricultural sector. The multi-scalarity of farm actors, interest and economic capacities have been some of the elements that have shown to give complexity to an eventual transition towards agroecology and agricultural sustainability, accompanied by an insufficient focus on public policies. However, a resource recovery system proves to be an important tool for continuous analysis on the matter....

Considering the expectations generated by new management approaches in food production, this study evaluated the effects of different agroecological practices on some physical properties of a soil belonging to the Rinconada Lo Vial Series (Inceptisol), located in the Maipú Commune, Metropolitan Region, Chile. Four sectors were studied, three of them with agroecological practices (application of various organic amendments as standard management and agroecological crop management) and the remaining one in transition to agroecology (unlike the other sectors, this one maintains fertilizer use), which was sampled to evaluate its stability over time and compare its results with those obtained in the agroecological sectors. Measurements were taken at two depth intervals (0-10 cm and 10-20 cm) with five replicates. The results indicate a low stability in the site in transition to agroecology, which increases its soil bulk density (Da) and decreases its coarse porosity and stability of microaggregates over time. On the other hand, it was observed that the use of swidden crops with the same root system does not generate major changes in soil, while the implementation of a “floral core” with different cultivated species and the consequent root diversity, promotes a higher macroporosity and stability of microaggregates. Finally, the fallow with a history of temporary grassland obtained low levels of both microaggregate stability and coarse porosity, so it is necessary to continue the evaluations of the proposed management over time....

Manejos agroecológicos asociados a la salud del suelo en la producción de hortalizas en Chile
(Universidad de Chile, 2022)

In the context of climate change, in which it is required to generate sustainable production systems to mitigate the difficulties that bring the changes in our climate and produce enough quality food, a bibliographical review about the main agroecological management that influences soil health is made to be implemented by small producers of vegetables in Chile. The work is focused on small producers since they are the most affected by the actual production systems, which required large investments in technology they cannot afford. For this reason, agroecology is considered a useful tool for small producers since it proposes a sustainable system with low production costs which reduces soil contamination and erosion, and offers economical and Ambiental benefits, in addition to the food security for the rural families and their environment. In this work, agroecology science, soil health, and the following agroecological management are conceptualized: conservation tillage systems and agroecosystem diversification. Furthermore, in this work it is possible to observe the effect that the main agroecological management has on soil health improvement by modifying its physical, chemical, and biological properties. Which improves the horticultural production, the plant's health, and the quality of the environment. In conclusion, agroecology and specifically its soil management practices are an important alternative to generate a sustainable production system in times of climate change, which improves the soil and contribution to vegetable production....
