The present review retraces the steps of the industrial and agriculture revolution that have taken place up to the present day, giving ideas and considerations for the future. This paper analyses the specific challenges facing agriculture along the farming supply chain to permit the operative implementation of Industry 4.0 guidelines. The subsequent scientific value is an investigation of how Industry 4.0 approaches can be improved and be pertinent to the agricultural sector. However, industry is progressing at a much faster rate than agriculture. In fact, already today experts talk about Industry 5.0. On the other hand, the 4.0 revolution in agriculture is still limited to a few innovative firms. For this reason, this work deals with how technological development affects different sectors (industry and agriculture) in different ways. In this innovative background, despite the advantages of industry or agriculture 4.0 for large enterprises, small- and medium-sized enterprises (SMEs) often face complications in such innovative processes due to the continuous development in innovations and technologies. Policy makers should propose strategies, calls for proposals with aim of supporting SMEs to invest on these technologies and making them more competitive in the marketplace.

Swimming pools are together an exemplificative outcome of urban sprawl and an indicator of socio-spatial polarizations in metropolitan regions. A comparative analysis of the spatial distribution of pools in three Mediterranean cities (Barcelona, Rome and Athens) provides an alternative reading of recent urbanization in southern Europe, questioning the supposed homogeneity in socioeconomic patterns and processes across the region. In the present study, the socio-spatial structure underlying dispersed urban expansion in these three cities was studied using 53 background indicators at the spatial scale of municipalities. Four indicators were proposed to study variability in the spatial distribution of pools. Relevant differences between cities were observed in the density of pools, reflecting heterogeneous patterns of dispersed urbanization and class segregation: socioeconomic polarization in Athens, settlement scattering and social mix in Rome and a more balanced socio-spatial structure in Barcelona. The spatial distribution of pools in the three cities was found associated with different socioeconomic factors, outlining the role of spatial disparities between high-income and low-income neighbourhoods, the diverging economic base and place-specific attributes. Results from Barcelona, Rome and Athens case studies provide contrasting views of the relationship between class segregation and the local socioeconomic context. The resulting patterns of sprawl reflect distinct urban models belying the supposed homogeneity of the ‘Mediterranean city’ archetype.
