Depopulation is a major challenge for many rural inland areas, as is the case in a considerable number of rural municipalities in Galicia (north-western Spain). The pandemic had a considerable impact on internal migration in 2020, but it was far from being anywhere near high enough to reverse the ongoing trend of population decline, highlighting the need for further action. Thus, this paper has a twofold objective: firstly, to propose an index of rural sustainable development for the rural Galician municipalities, and secondly, to identify the factors related to it. In so doing, a composite index stemming from the Benefit of the Doubt methodology has been proposed in the first stage, an index built from four-dimension factors– economic, demographic, social, and environmental. The empirical evidence of this index has been compared with three additional ones (namely, common weights, super-efficiency, and geometric mean and logistic normalization models). In the second stage, the relationship between the composite index and a set of exogenous variables that affect rural development has been analyzed, the data confirming that the rates of female immigration and occupancy in the hospitality sector favors sustainable development, whereas the distance from the provincial capital hinders it. This paper paves the way for an assessment of the potentialities of each territory, and the evidence found allows actions to be supported that generate sustainable progress in rural Galician municipalities and that are useful for tackling this complex problem. • A new rural sustainable development index based on four dimensions is proposed. • Strengths and weaknesses for each Galician rural municipality are identified. • Environmental factors constitute a driver of rural development in Galicia. • Social aspects (i.e., health, education, services) stand out as main weaknesses. • Policies to boost social care and attract childbearing-age inhabitants are paramount.

Wine is the main economic resource in the 'Area of Jerez', located in the south of Spain. It is one of the most important wine tourism destinations in the world. However, its sustainable production process, so strongly influenced by climatic conditions, can be clearly affected by the phenomenon of global warming. The ageing process of "Sherry wine" takes place in buildings known as 'Cathedral warehouses', an example of Nearly-Zero Energy Buildings (NZEBs). For centuries, they have been used to provide specific ecological conditions for biological ageing without any type of mechanical heating/cooling system. The purpose of this paper is to assess the impact of climate change on this production model. For this, the annual thermal behavior of a representative winery was monitored during several years. The first energy simulation model of this type of buildings was developed and validated (daily R2 = 99%; hourly R2 = 97%). Finally, the model was simulated by modifying the outdoor climatic conditions (9 years training data sets) for a climate change scenario, applying the 'morphing' method for the transformation of the weather data. The results show that, by the middle of this century, the average outdoor temperature will increase by 2.3 °C (in summer up to 3.6 °C). As a consequence, the temperature in the ageing zone would exceed the comfort limit for 19% of the year, (up to 34% in hot years). For 2080, the prediction is even worse (average value of 27%). As a result, the microorganisms responsible for this unique process could not maintain their activity. This fact will force the sector to face a harsh reconversion through the adoption of new mechanisms and strategies, which endangers the economic sustainability of an entire region dedicated to this practice. Beyond the specific case, the work highlights the need to evaluate the future behavior of NZEBs through simulation. [Display omitted] • Assess the impact of climate change in a Near Zero Energy Building. • "Cathedral warehouses" will lose their usefulness by the middle of this century. • Comfort limits will be exceeded 19% of the year, interrupting biological ageing. • The economic sustainability of an entire region would be endangered. • The need to evaluate the future behavior of Near Zero Energy Building is highlighted.
