- ItemOpen AccessPolíticas públicas locales: una pieza clave para la transición agroecológica(Servicio de Publicaciones. Universidad de Murcia, 2025) López-García, D.; Di Paula, M.; Cruz Maceín, José Luis; Sin departamento asociadoThe local scale and the territorialization of food policies are gaining interest as central elements for addressing the challenge of achieving a more sustainable and just food system. The main responsibilities for food policy lie with the Ministry of Agriculture, Fisheries and Food, and their implementation in the territory is the task of regional governments. This organization allows for the articulation of the entire agri-food system. However, the impetus that local food policies can provide at each link of the food chain is increasingly necessary. This article reflects on the areas where local policies are currently having an impact and how they can promote the agroecological transition. To this end, the results obtained from interviews conducted with political decision-makers (n=10) from municipalities in the Community of Madrid are systematized. All interviewees are council members and councillors who currently hold positions of responsibility, or who left these roles in the last municipal elections. Specifically, the degree to which the agroecological approach is present in the discourse of these council members is reviewed, as well as the level of prominence they assume in the agri-food sector within an urbanized context like the entire Madrid region. The conclusions suggest that regardless of the territory’s political orientation and agricultural vocation, there is great potential at the local scale to drive the agroecological transition. However, this requires articulating a system that integrates the different roles of the three administrative scales: Ministry, Autonomous Community, and Municipality.
- ItemOpen AccessEvolución de las propiedades físicas y químicas de un suelo de regadío en la conversión de tradicional a ecológico(Servicio de Publicaciones. Universidad de Murcia, 2025) Virto-González, D.; Mateos, I.; González-Barragán, María Isabel; Sin departamento asociadoThe present work analyzes the evolution of the physicochemical properties of irrigated soil during the conversion process from traditional to organic agricultural practices. The studied farm is located at the University School of Agricultural Engineering INEA (Valladolid). This irrigated farm was converted to organic agriculture in 2006. The study covers the period from 2004 to 2020. The agricultural practices adopted for the conversion to organic included: elimination of fertilizers (using organic sheep manure when it was the turn for potatoes in the rotation), crop rotation (incorporating legumes in alternate years), elimination of tillage, and incorporation of crop residues from the previous harvest. Three distinct plots within the INEA farm were monitored. Periodic analyses of key parameters such as pH, nitrogen, phosphorus, potassium, organic matter, and carbon/nitrogen ratio, among others, were conducted. The results obtained reveal significant changes in the chemical properties of the soil, showing an improvement in its quality, with an increase in organic matter and nutrients and a decrease in salts. This study provides a comprehensive view of soil quality parameters, which have environmental and agronomic benefits for adopting more sustainable approaches in agriculture. The findings contribute to scientific knowledge about the importance of soil management in promoting more environmentally friendly and resilient agricultural systems in the long term.
- ItemOpen AccessEstudio de la repercusión del color en las propiedades nutricionales de las zanahorias de 19 producción ecológica(Servicio de Publicaciones. Universidad de Murcia, 2025) Zambrano, T.; Esteve Ciudad, Patricia; García-Martínez, M.D.; Raigón, María Dolores; Sin departamento asociadoThe carrot (Daucus carota) is a widely consumed and appreciated vegetable around the world. Its importance lies not only in its culinary versatility and sweet, earthy flavor but also in its nutritional value and health benefits. Carrots are highly valued for their abundant β-carotene content, a precursor of vitamin A. The diversity of carrot colors ranges from the classic orange to purple, yellow, and white. The orange carrot is known as the Nantes type, while the others are known by their color (white, yellow, and purple). Each color indicates the presence of different phytochemical compounds, which can have specific health benefits. Therefore, understanding the relationship between color, the quantification of compounds and the nutritional properties of carrots is essential to maximize their nutritional and health potential. The main objective of this study is to evaluate how the color of carrots produced using ecological techniques influences their nutritional content and potential health benefits. The results indicate that color does not influence the concentrations of fiber and fat, but it does affect the contents of carbohydrates, protein, vitamin C, carotenoids, and anthocyanins. Furthermore, while the concentration of total polyphenols is not influenced by carrot color, the total antioxidant capacity is higher in purple carrots.
- ItemOpen AccessResiliencia antes las crisisrecientes de la ganadería caprina agroecológica. Un estudio de caso en la Sierra de Cádiz(Servicio de Publicaciones. Universidad de Murcia, 2025) Mancilla Leytón, Juan Manuel; Prat Benhamou, Alicia; Lizarralde, Joseba; Martín Collado, Daniel; Morales Jerrett, Eduardo; Mena Guerrero, Yolanda; Sin departamento asociadoFrom an agroecological perspective, a sustainable agroecosystem is characterised by attributes, including resilience. The aim of this study was to determine the influence of different shocks and trends on the management and results of an agroecological pastoral dairy goat farm in the Sierra de Cádiz and to analyse the key elements of its resilience. Information was collected for 6 years (2018 to 2023) and technical, economic and environmental indicators were generated with the AmalteUS programme, which were analysed and discussed with the farmer and their perception of resilience was also addressed. From 2020 onwards, there was an increase in production costs as a result first of a change in management, and then of an increase in the price of concentrates and energy due to the war in Ukraine. This increase in costs was not sufficiently compensated by income, resulting in a continuous decrease in disposable income between 2019 and 2022. However, in 2023, this situation was reversed and the farmer managed not only to overcome the crisis, but also to reach the profitability levels he had before the crisis. The key elements for the resilience of this livestock farming were: having natural reserves (grazing surface) and capital, having competent technical staff, having a genetically good herd, carrying out a correct technical-economic management and being related to different entities with which to contrast their management strategies.
- ItemOpen AccessAnálisis de metales pesados en chufa de producción ecológica y convencional como un 5 potencial indicador de calidad(Servicio de Publicaciones. Universidad de Murcia, 2025) Castell Zeising, Vicente; Noguera, P.; García-Martínez, M.D.; Raigón, María Dolores; Sin departamento asociadoThe tiger nut (Cyperus esculentus L.) is a perennial herbaceous plant from the Cyperaceae family. It is traditionally cultivated in the region of L’Horta de València. A small tuber (also called tiger nut) is harvested for human consumption, either raw (dried or hydrated) or for making horchata (a refreshing beverage obtained by mixing the extract of crushed tiger nuts with water and sweetened to taste). Locally, there is growing concern about the quality of tiger nuts for making horchata and the risks, both environmental and to human health, due to possible exposure during cultivation and the consequent risk of absorption by the plant. The environmental conflict is magnified by the persistence in the L’Horta ecosystem of soils with appreciable concentrations of heavy metals, affecting everything from the metabolic processes of organisms to environmental processes that impact public health. The main objective of this study is to analyze the composition of fresh tiger nuts and assess the risk of exposure and accumulation of heavy metals, distinguishing between tiger nuts produced using ecological and conventional techniques. The results show the presence of cadmium, lead y mercuric in tiger nut tubers, with no distinction between the two production systems, although the concentrations are very low to constitute a health risk.
