Humans have traditionally sought provisioning services from rural areas, but society is becoming increasingly aware of other services that rural areas provide to human beings, agroecosystem services. At the same time, however, certain dysservices can be identified. The analysis of agroecosystem services and dysservices is a key point to consider in decision-making processes and provides a tool for acting on sustainability. Notwithstanding, few approaches to the dairy sector exist with this focus, and they often do not incorporate the vision of the actors from the entire value chain. The aim of the present paper is to identify agroecosystem services and dysservices deriving from the dairy farming in Galicia (Spain), as perceived by actors linked to this sector. The methodology followed a bottom-up approach (Focus Group) and identified 19 agroecosystem services (S) and 9 dysservices (D) grouped into four main categories: provisioning (6S/0D), environmental quality (5S/5D), rural vitality (6S/2D), and cultural heritage and quality of life (2S/1D). The results show strong awareness of services and dysservices, in particular as regards rural vitality (mainly related to employment and income generation) and environmental services (dyservices linked to intensive systems). We have, however, detected a significant gap in awareness of certain classical environmental services (carbon sequestration of pastures). Finally, one of the innovative findings is the identification of rural vitality services and dysservices, including the social role that farming plays in consolidating the population in rural areas, and in preserving local traditions and culture.

This study analyzes 174 tank milk samples taken from 89 commercial farms located all along the Cantabrian Coast (Green Spain). Sampling was performed in two periods: autumn 2016 and spring 2017. A survey was carried out for every day of sampling to record the average lactating dairy cow production and its diet composition. For each sample, the fatty acid (FA) profile (49 FA plus its main relationships) and nine fat-soluble antioxidant (FSA) profiles (retinol (vitamin A), α- and Υ-tocopherol (vitamin E), all-trans-β-carotene, 9-cis-β-carotene, 13-cis-β-carotene, lutein, zeaxanthin, and β-cryptoxanthin) were determined. The milk production varied between 7.3 and 45.9 liters per cow per day, highlighting the diversity found among production systems. The milk fat content ranged from 2.64% to 4.38% and the protein content from 2.87% to 3.56%. Regarding the fatty acids profile, the percentage of saturated fat varied between 59.95% and 75.99%. The linolenic acid content fluctuated between 0.21 and 1.31 and rumenic acid ranged from 0.20 to 2.47 (g 100 g−1 total FA). The most important correlations between diet and milk FA were always related to the content of fresh grass and total forage (which is defined by both fresh and conserved forage derived from fresh grass (GCF)) in the diet. The content of vaccenic acid, linolenic acid, total omega-3, rumenic acid, and total CLA isomers showed the highest correlation with the proportion of fresh grass in the diet. The antioxidant contents were also highly variable, although correlations with dietary components were lower. The highest correlations were between total forage content (fresh grass (FG) plus GCF) and lutein, all-trans-β-carotene, and 13-cis-β-carotene. Diets without fresh grass had lower omega-3 content, CLA, vaccenic acid, lutein, all-trans-β-carotene, and 13-cis-β-carotene.

Understanding the composition of a cow’s diet through the analysis of its milk is very useful in the linking of the product consumed with the systems involved in its production. The aim of this study is to show the diet–milk composition relationship using correspondence analysis and multiple linear regression analysis. This study analyzed 174 tank milk samples taken from 89 commercial farms located in “Green Spain”. Sampling was performed in two different periods: autumn 2016 and spring 2017. The correspondence analysis allowed for study into the general relationships between diet components and their relationship with the composition of milk (chemical composition, fatty acid profile (FA), and fat-soluble antioxidants (FSA)). The model used to estimate the percentage of fresh grass (FG) in the diet had a high predictive power (Raj 2 > 0.7), and the explanatory variables included in the model were linolenic acid (C18:3-n3), vaccenic acid (trans11-C18:1), and cis12-C18:1. The regression equation was applied to the 174 tank milk samples individually. To evaluate the equation’s predictive capacity, different thresholds for the dry matter percentage of fresh grass in the ration were marked (15%, 20%, 25%, and 30%), above which milk could be considered “grass-fed milk”, and below which, “not grass-fed milk”. The equation is considered valid when it correctly classifies the sample. The highest percentage of success (89.7%) was obtained by marking a threshold of 25% FG. When analyzing the misclassified milk samples, that is, where the equation did not classify the milk sample well according to its fresh grass composition, it was observed that the majority of cases corresponded to milk samples that came from herds fed with fresh grass above the marked threshold (>25%) but with a high content of concentrate in the ration. The conclusion is that the percentage of concentrate in the diet has a very important influence on the fatty acid profile of milk, particularly with respect to fresh grass. This is in such a way that anywhere above a concentrate content of >30%, the equation’s capacity to estimate the percentage of fresh grass decreases.

Vista la relevancia territorial de la producción ecológica en España y el contexto caracterizado por un fuerte aumento en la demanda interna de productos ecológicos, este trabajo tiene por objetivo estudiar en un ámbito local (ciudad de Lugo), los hábitos de consumo hacia los productos ecológicos. Se realizaron 177 encuestas personales directas a finales de 2019 a consumidores en tres tipos de establecimientos comerciales, mediante un muestreo aleatorio estratificado por sexo y edad de población.Los resultados confirman un gran conocimiento de lo que son los productos ecológicos, cuyo consumo se produce en 4 de cada 5. La mayor frecuencia de consumo es una vez por semana, siendo las frutas y verduras el producto más consumido. Factores como la edad, nivel de ingresos, formación, hábitos de vida se correlacionan con el consumo. El origen local del producto es el atributo al que el consumidor presta mayor atención y existe una predisposición a pagar un sobreprecio por un producto ecológico, de media del 44%.

This study characterizes, from a productive and socioeconomic point of view, the cattle farms in Cantabrian Cornice and Spain, besides analyzing recent evolution of the main adjustment indicators between 2007 and 2016. In doing so, we have analyzed the main agricultural magnitudes, relative to the number of farms, land, livestock, labor and economic value of production. The results obtained show a territorial concentration, specialization and productive concentration of the cattle, together with an advance of the structural adjustment process.
