Exploring Andalusia's Rich Heritage through Surveys: Pastoral Livestock Farming as a Tourist Attraction Resource.

This study aimed to analyze the interest, willingness to pay, and profile of tourists participating in specific agrotourism activities linked to extensive livestock farming in order to encourage the development of those activities that are most demanded by tourists, as well as to support the proposals for improvements to promote this kind of tourism in the region of Andalusia (Spain). For this purpose, a survey was conducted, which was organized into six sections: (i) sociodemographic data, (ii) general aspects of tourism, (iii) rural tourism, (iv) livestock farming and tourism, (v) benefits of extensive livestock farming, and (vi) tourism activities linked to livestock farming. A total of 892 responses were received, out of which 753 were analyzed.

Energetic and Monetary Analysis of Efficiency in Family-Owned Dairy Goat Production Systems in Andalusia (Southern Spain).

The family-owned dairy goat sector in Andalusia presents great diversity. Taking into account the particularities of their economic strategies, which are focused on generating net value added and a stable long-term remuneration for family labor, this work aims to expand the scarce existing knowledge on the energetic and economic profiles of the different caprine management systems in a context of climate and energy crisis. For this purpose, twenty-one farms, representatives of the four typologies of the Andalusian dairy goat system, were monitored for one year: pastoral systems, grazing systems with high feed supply, indoor systems with associated crops, and indoor systems without associated crops.

Evaluation of batch mesophilic anaerobic digestion of waste Euro banknotes for methane Production: Preliminary studies and kinetic approach.

The European Central Bank is striving to find environmentally friendly alternative methods of waste disposal. In 2020, it decided to end the disposal of Waste Euro Banknotes (W€B) in landfills and planned to use them for recycling and/or energy recovery. Despite being recognized as an effective tool in a circular economy model, there are no reported studies on the use of W€B as a substrate in anaerobic digestion (AD).

A Comparative Analysis of Carbon Footprint in the Andalusian Autochthonous Dairy Goat Production Systems.

The small ruminant livestock sector faces the challenge of reducing greenhouse gas (GHG) emissions. Carbon footprint (CF) studies on dairy goats, the most widely used indicator to quantify the impact of livestock farming on global warming, are still few. The aim of this study was to calculate the CF of the different production systems of autochthonous dairy goat breeds presently occurring in Andalusia (S Spain) and identify systems and practices that can minimize their environmental impact in these terms.

Reuse of the digestate obtained from the biomethanization of olive mill solid waste (OMSW) as soil amendment or fertilizer for the cultivation of forage grass (Lolium rigidum var. Wimmera).

The principal by-product from the two-phase olive oil production process is olive mill solid waste (OMSW). It is a highly-pollutant by-product, not only because of its characteristics, but also because of the considerable volume of OMSW which is generated, amounting to 2 to 4 million tons per year in Spain. The anaerobic digestion of this by-product is a well-studied process, and results in the generation of biogas, methane and carbon dioxide mainly of high calorific values (20-25 MJ m), and an effluent or digestate.
