Summary
The livestock sector is currently facing a crucial moment, as it grapples with the challenge of finding solutions that allow for more efficient and sustainable production while ensuring animal welfare. Particularly in pig fattening, it is essential to provide adequate facilities that meet quality standards in terms of air, temperature, humidity, and control of gases and microorganisms. The quality of the environment in livestock facilities directly affects the health and well-being of the animals. An unsuitable environment can increase stress, susceptibility to diseases, and hinder the normal development of pigs. Environmental control promotes healthy growth, feed efficiency, and overall performance. Environmental care is an increasingly relevant aspect, as sector-specific legislation becomes stricter in terms of environmental regulations, and consumers demand more animal products that come from animals raised under optimal conditions. This implies reducing the negative impact of greenhouse gas emissions and other pollutants generated by livestock activities. To achieve these goals, it is necessary to carry out an environmental characterization of livestock facilities and understand how these conditions relate to productive outcomes and animal welfare. Only through a comprehensive analysis of these factors will it be possible to establish appropriate parameters that ensure a balance between productive efficiency and respect for animal welfare.

Summary
In recent years, the structure of the European farms has undergone significant changes: the decrease in the number of farms and the increase in the average farm size, and the ageing of farm owners. As the number of successions and traditional farm entry pathway is decreasing, the number of people starting their agricultural career without previous experience are starting to find their niche. These are referred to as new entrants (NE) in agriculture, people who have no family ties or previous experience in the sector and who access the sector, in many cases, bringing skills and experience in various fields, together with other very particular characteristics. In order to find out the current status and characteristics of this profile in Galicia, an exhaustive review of the academic literature was carried out, and an attempt was made to adopt a definition of what a new entrant is. Subsequently, through the design of a questionnaire based on the characteristics of NEs in Europe, data were collected from a sample of new entrants in Galicia over the last ten years and analysed quantitatively and qualitatively. Once the results were obtained, possible patterns were interpreted and identified which, although close to the European NE profile, also show particular characteristics. Our results showcase a high heterogenity in terms of land tenure, labour origin or profitability, as well as showing a clear commitment to agroecology. This study opens a window into further research that will also put more effort into the qualitative characterisation and externalities that mould these people in the agricultural sector.

Technical-economic analysis of galician grazing beef farms

Summary
Beef production faces new challenges that compromise its viability. Challenges that range from the achievement of economic profitability, conditioned by the unfavourable evolution of the relationship between received and paid prices, to the need of face greater environmental demands. With this negative context, the need arises to study the profitability of the sector, focusing on grazing livestock, since they combine cost reduction and environmental sustainability. Furthermore, these types of livestock farms are crucial at territorial level, due to the great impact in rural areas both economically and socially. This prevents depopulation due to the dynamization that the activity entails. However, it must be considered that there are different models of grazing beef farms, with different profitability, which is why they must be characterized in typologies. For this reason, a double multivariate analysis was carried out (analysis of principal components and hierarchical clusters) based on data collected (from the year 2022) from farms within the framework of the “Carne de Vacún a Pasto” Operational Group. Thus, the farms are classified according to their profitability, and then link this with the management of the farm. The objective is to determine which are the most profitable management models and to know the possibility of exporting them to other cases, improving profitability to allow sustainability over time. In addition, it is necessary to know the limitations they have to continue with the activity in the future, as well as know the reasons that hinder organic production, which constitutes an interesting market at the present and with growth potential. To gain a deeper understanding of the farms, a survey was proposed, which would serve to understand the operation of the farms the problems they encounter, both in daily operation and in the future.

Summary
Photogrammetry is a widely used technique, and although many of its applications have already been explored, there are still areas where its potential could be useful. From this perspective, society's concern for landscape preservation is growing, making the assessment of visual impact of new infrastructures increasingly relevant for any project. That's why in this research, its applicability for obtaining infographics of projected elements in the Careón Wind Farm, between the municipal terms of Toques (A Coruña) and Palas de Rei (Lugo), was studied. From the constructed elements present, the geometric precision of the proposed methodology is verified using two techniques. In the first, contrast points (checkpoints) are used to compare the observed location with the expected location. In the second, aerial photogrammetry is performed to generate a mesh of the elements of interest that overlay on oriented images. This demonstrates the geometric assurances provided by SfM photogrammetry for infographic development. All of this entails previous work in photography planning and scene georeferencing, determining both the perspectives to be taken in the study area and the camera parameters or target distribution, followed by image processing with specific software. The results regarding the accuracy of the infographics showed better responses for distant perspectives than for short and medium distances. Therefore, this technique could be implemented for environmental impact assessment using photographs taken on site as an efficient, cost-effective, and precise method.

Summary
This project will be carried out with the aim of constructing a wine industry for the establishment of a winery with a capacity of 40,000 liters per year of Mencía wine with D.O. Ribeira Sacra, which will be located in the Chantada Industrial Park, in Chantada, Lugo. For the construction and design of the building, all relevant conditions have been taken into account: legal, food industry, those of the promoter, etc. In the production line, 40,000 liters of Mencía red wine will be produced, for which 65,000 kg of grapes are required. The raw material will go through all the necessary activities to leave the winery ready for commercialization. The stages that will be carried out during the production process are as follows: grape maturation and harvest, prefermentative operations (pressing, must refrigeration, sulfiting, and static cold settling, as well as all the auxiliary operations and controls that accompany them), fermentative operations (alcoholic fermentation and wine racking, each with its due controls), and postfermentative operations (wine refrigeration, tartaric stabilization, filtration with horizontal disc filters, bottling, storage, and dispatch). This is detailed in the corresponding annexes, process engineering, and implementation of the production process, where the necessary machinery for the correct development of the process activities is also cited. All calculations for the construction of the building will also be carried out, as well as all the necessary installations (electrical, plumbing, sanitation, refrigeration, and fire protection installations). We include a budget document, detailing the costs for the project, which amount to €983,406.10, as well as an economic evaluation study where it is determined that the project is economically viable, and an annex for the work schedule, where it is calculated that the duration of the project will be 86 days.
