| A study that aims to provide comprehensive solutions for the environmental sustainability of pigs | The City Council of Fuente Álamo and the Polytechnic University of Cartagena (UPCT) have signed an agreement by which the chair on 'environmental management for the sustainability of intensive pig farming' is launched.
A chair that will be led by the Research Group Management, Use and Recovery of Soils and Waters of Dr.
Ángel Faz Cano. These investigations will serve to promote comprehensive solutions aimed at the environmental sustainability of pigs, improving the practices and techniques of the sector, as well as promoting the dissemination and knowledge (to the general public, but also within the academic and scientific community) of all related aspects.
with the environmental adaptation of livestock for its sustainability. The municipality of Fuente Álamo represents 80% of the intensive livestock farming in the watershed of the Mar Menor, with 289 pig farms and more than 800,000 pigs.
A scenario in which sustainable livestock farming is governed by Royal Decree 306/2020, which establishes basic rules for the management of intensive pig farms, and Decree Law 2/2019 on the Comprehensive Protection of the Mar Menor. That is why, in the words of the Mayor of Fuente Álamo, Juana María Martínez: "The City Council, concerned about the situation of the Mar Menor and the sector, is launching these studies in the hands of the ranchers and integrating companies that they operate in the municipality, of course, with the support of the Regional Government.
" The event, held in the Agrarian Chamber of Fuente Álamo, was also attended by the Minister of Agriculture, Livestock, Fisheries and the Environment of the Autonomous Community of the Region of Murcia, Antonio Luengo, who stressed that "these studies seek to propose alternatives for the environmental improvement of the sector and promote integral solutions aimed at the environmental sustainability of the pig ". The rector of the UPCT, Alejandro Díaz, has explained that during the first year, the actions will focus on the environmental impact in the subsoil of the storage rafts and slurry evaporation existing on farms, for which it is proposed to study 4-6 representative scenarios in the first 12 months of the chair.
Also, alternatives for sustainable management and recovery of slurry will be analyzed: available technical improvements-emission mitigation-conservation and sustainable nutrition of agricultural soil. In addition to these investigations, expert meetings will be promoted through national and international conferences and seminars; and collaboration will be facilitated in the practical training of UPCT students on the subject of the chair, as well as participation in the scheduled activities of the UPCT Chair and Engineering and Business Campus.
On the other hand, there will be tutorials for the completion of Final Degree Projects, Final Degree and Master's Final Projects, Doctoral Theses and other specific projects of special interest. Lines of work of the chair The researcher Ángel Faz has commented that the first year of execution of the chair, the first line of work will study the 'Environmental impact in the subsoil of the storage rafts and slurry evaporation existing on farms', with the aim of being able to decipher whether there is or has been affection to the subsoil from a certain slurry raft.
For this, the methodology of Martínez and Faz will be used, which proposes the use of the geophysical technique of electrical tomography and is based on the fact that the pattern of the area affected by the slurry corresponds to a region that extends laterally and downwards, the latter will come conditioned to the type of materials that make up the subsoil, since there are materials with waterproof characteristics that retain the slurry in the surface layers.Together with the execution of probes with core extraction for the subsequent physicochemical analysis of the extracted samples, a 3D subsoil and basin map is obtained. The electrical tomography has proven to be an ideal methodology to study the areas of affection in the subsoil by slurry, both in non-waterproofed rafts, as well as those that are, but the coating is damaged or deteriorated, thus not meeting the sealing characteristics.
that are demanded of him.
This line of work aims to study 4 to 6 representative scenarios in the first year of teaching. In addition, a second line of work will be developed that will analyze 'Alternatives for sustainable management and recovery of slurry: available technical improvements-emission mitigation-conservation and sustainable nutrition of agricultural soil'.
With this, the aim is to optimize the management and recovery of slurry, as well as obtaining quality fertilizers / amendments to implement development and soil improvement, carbon sequestration (reduction of carbon footprint) and reuse of purified liquid effluents (water footprint).
, following the principles of circular economy and sustainable nutrition of agricultural land. This study also aims to improve the systems for applying slurry to the soil, seeking to minimize nuisance to neighbors due to odors and mitigating emissions of ammonia and GHG.
In this way, work will be carried out in the context of the implementation of the Technical Improvements Available in pigs. The chair on 'environmental management for the sustainability of intensive pig farming' is financed by the City Council of Fuente Álamo and the pig integrating companies in the municipality: Adespofa, Agropecuarias Casas Nuevas SA, Agropork SL, Cefu SA, Inga Food SA , Juan Jiménez García SAU, Piensos Cartagena SL and Porcisan SA.
