“…Incorporating the technical and economic principles of agroecology (Sevilla-Guzmán and Soler 2010) has the potential of not only mitigating GHG emissions, but favoring biodiversity conservation (Altieri 2002), increasing soil organic matter (Simón, Montero, and Bermúdez 2020), decreasing dependency on fossil fuels (SOCLA 2015), maintaining ecosystem services, and reducing pollution associated with agricultural practices, among other effects. (Aguilera et al 2020).…”

This work evaluates and discusses the greenhouse gas (GHG) emissions reduction potential of agroecological policies implemented in public food procurement for school canteens. Using a life cycle analysis (LCA) methodology (cradle-to-grave approach) and the information gathered from the Red Municipal de Comedores Escolares (Local Network of School Canteens) in the municipality of Ames (A Coruña, Galicia, Spain), the results show how organic production, dietary change (less animal protein), seasonal consumption, and packaging reduction, among other measures, can mitigate the climate impact of school meals. The food policies implemented in Ames have allowed mitigating the GHG emissions of local school canteens by 13.4%. Under realistic conditions, this reduction could rise to 40.6% should the agroecological transformation of the food system continue to advance.

“…Por ende, dos de los principios básicos de esa ciencia: optimizar la disponibilidad de nutrientes y garantizar que las condiciones del sistema suelo sean favorables para el desarrollo de las plantas (Snapp, 2017;Aguilera et al, 2020;Hale et al, 2020), podrían estar relacionados directamente con la aplicación del biochar, pues este cumple dichas funciones y evita así la degradación del suelo. Además, diferentes estudios (Mohan et al, 2018;Hale et al, 2020;Saletnik et al, 2018;Ferjani et al, 2020) mencionan que durante el proceso de producción del biochar se generan cenizas, que contienen los micronutrientes que el suelo necesita y evitan la quema de residuos agrícolas.…”

El biochar es una alternativa de acción climática, accesible, de bajo costo y sostenible. Su aplicación como enmienda permite incrementar la fertilidad del suelo y reducir las emisiones de gases de efecto invernadero como el CO 2. Por ende, es necesario implementar el biochar como tecnología de emisión negativa frente al cambio climático, disminuir los impactos negativos en el ambiente y salvaguardar la salud de las personas. La investigación es una revisión de literatura holística y sistemática disponible sobre el uso del biochar como estrategia de mitigación, debido a su capacidad de secuestro de carbono, y sobre el potencial de sus aplicaciones e interacciones que presenta con el clima, la seguridad alimentaria y los componentes del ecosistema. Se encontró que el potencial de secuestro de carbono presentado por el biochar en equivalencias de CO 2 supera las 20 GtCO 2 eq por año. Esto es muy significativo en la búsqueda de tecnologías de emisiones negativas eficientes que ayuden a reducir las emisiones de CO 2 que generan las actividades antropogénicas anualmente.

“…As in other Mediterranean zones, agriculture in central Chile is currently conducted under vulnerable conditions and is characterized by different forms of soil degradation (e.g., soil organic matter decline), water scarcity or overuse, disrupted nutrient cycles, land use change, high dependence on biomass and energy imports, and a prevalence of highly specialized and low-diversity agroecosystems. This scenario of vulnerability is also described by Aguilera et al (2020), who urged the rapid adoption of systemic measures to increase the resilience of production systems and precision agroecological practices with high adaptation potential through the generation of local knowledge based on the integration of scientific and traditional ecological knowledge. Similarly, Ryan and Peigné (2017) concluded that agroecology, as a scientific discipline, will help facilitate efforts to respond to the actual challenges of agricultural production due to of increasingly applied systems thinking and interdisciplinary research approaches.…”

A number of agroecological practices have been proposed for assessing soil quality. Several physical soil properties have been shown to be important for determining soil quality by using the sustainability index (SI) and the cumulative rating approach. The main aim of the study was to determine the effects of different agroecological managements on the physical properties of a Mollisol in the Mediterranean central Chile. In addition, some physical properties were selected to compare the soil quality among different agroecological management practices and highly mechanized intensive systems by using the SI and cumulative rating approaches. An experimental field was defined in an area of 3.5 ha in 2014. Four sites with different agroecological practices were selected in 2019 to assess soil physical properties: rainfed Mediterranean annual prairie - no tillage (1-S), irrigated perennial prairie with deep-root species - no tillage (2-N), irrigated annual and perennial prairie - conventional tillage (4-S), irrigated vegetables and flowers - minimum tillage (4-N); an avocado orchard with traditional management was used as the control. Soil organic carbon and the following soil physical properties were selected to assess SI and CR: bulk density, total porosity, void ratio, air capacity, fast-drainage pores, relative field capacity, hydraulic conductivity, structural stability index and unavailable water pores. The applicability of the selected physical indicators to the SIs of agroecological management practices compared with the control was demonstrated. The cumulative rating index (CR) for each land use showed that all agroecological practices constituted sustainable soil management (25≤CR<30), whereas the avocado orchard showed the least sustainable management (30≤CR<40), and a change in soil use is recommended.
