Chapter 8 situates Livorno amidst a larger picture of competition in the central Mediterranean. It analyzes the spread of free ports by considering the two axes along which Italian ports liberalized during the early modern period: hospitality toward merchants and openness toward goods. Despite much institutional variation, a maritime free trade zone was in existence by the mid-eighteenth century. The intellectual legacy of free ports such as Livorno was nonetheless ambivalent. Though some Enlightenment thinkers used free ports to formulate general theories of free trade, others believed they promoted the subjection of state policy to foreign merchants.

Quantitative Examination

Chapter 6 offers a quantitative examination of the commercial development of Livorno, showing how it plugged local and regional exchange networks into the currents of global commerce. Livorno was at the epicenter of the reorganization of maritime trade in the Tyrrhenian and throughout the Mediterranean. Despite dense connections between north-central Italy and the free port, however, international commerce did not substantially affect productive relations in the hinterland. North-central Italy remained an autonomous region; rather than a colonial outpost subservient to northern capitalism, Livorno was a large marketplace connecting otherwise distinct economies. The Tuscan city’s success in organizing trade eventually provoked a competitive response by neighboring ports.

Free Port

Chapter 5 examines the creation of the classic free port, which taxed only for commercial services. The latter half of the seventeenth century inaugurated an age of conscious experimentation in economic policy. Amidst intensified commercial competition throughout the central Mediterranean, the Medici regime launched a panel of interventions aimed at improving the grand duchy’s economic position. For Livorno, this program culminated in the reform of 1676, which eliminated import/export duties and simplified collection procedures. This reform constituted an important moment in the development of commodity markets and secured Livorno’s role in brokering trade between northwestern Europe, Italy, and the Levant.

First Arrival

The Central Mediterranean is the most deadly body of water in the Mediterranean Sea with at least 15,062 fatalities recorded by International Organization of Migration between 2014 and 2018. This article aims at highlighting the rise of a variety of new civil society actors engaged in the rescue of people undertaking dangerous journeys across the sea in the attempt of reaching the southern European shores. The peculiarity of the humanitarian space at sea and its political relevance are pointed out to illustrate the unfolding of the maritime border management on the Central Mediterranean route and its relation with the activity of the civil society rescue vessels. The theoretical aspiration of the article is to question the role of a proactive civil humanitarianism at sea, discussing the emergence of different political and social meanings around humanitarianism at the EU’s southern maritime border. In recent years, the increasing presence of new citizens-based organizations at sea challenges the nexus between humanitarian and emergency approaches adopted to implement security-oriented policies. This essay draws on the findings of a broader comparative work on a variety of civil society actors engaged in the search and rescue operations on the maritime route between Libya and Europe, focusing in particular on Italy as country of first arrival. The fieldwork covers a period of time going between 2016 and 2018. The research methodology is built on a multisited ethnography, the conduct of semidirective and informal interviews with both state and nonstate actors, and the analysis of various reports unraveling the social and political tensions around rescue at sea on the Central Mediterranean route.

Abstract Chlorine is a minor element present in obsidians in quantities greater than in average igneous rocks. The chlorine concentration in obsidians is generally low, of the order of tenths of wt %, but it exhibits an appreciable differentiation among geological sources. Despite these characteristics, chlorine has rarely been taken into consideration as a possible indicator of obsidian provenance and it does not appear in the chemical analytical tables accompanying the geochemical characterisation of obsidian samples. In this work, after an overview of chlorine geochemistry and cycle, we present thirty-one new electron microprobe (EPMA) analyses, including Cl, of geologic obsidians sampled from the four sources of the Central Mediterranean, exploited in prehistoric times (Monte Arci, Palmarola, Lipari and Pantelleria). The results are compared with 175 new EPMA analyses, including Cl, of archaeological obsidians already characterised in previous work and of known provenance. As such it was possible to ascertain that each source has a characteristic chlorine concentration, showing the utility of its use in the studies of obsidian provenance. Furthermore, given that the solubility of chlorine in silicate melts is correlated to its alkali content, in particular sodium, we assessed the efficacy of simple binary graphs Cl vs Na2O to better constrain the provenance of the obsidian samples.

A satellite algorithm able to identify Dust Aerosols (DA) is applied for a climatological investigation of Dust Aerosol Episodes (DAEs) over the greater Mediterranean Basin (MB), one of the most climatologically sensitive regions of the globe. The algorithm first distinguishes DA among other aerosol types (such as Sea Salt and Biomass Burning) by applying threshold values on key aerosol optical properties describing their loading, size and absorptivity, namely Aerosol Optical Depth (AOD), Aerosol Index (AI) and Ångström Exponent (α). The algorithm operates on a daily and 1° × 1° geographical cell basis over the 15-year period 2005–2019. Daily gridded spectral AOD data are taken from Moderate Resolution Imaging Spectroradiometer (MODIS) Aqua Collection 6.1, and are used to calculate the α data, which are then introduced into the algorithm, while AI data are obtained by the Ozone Monitoring Instrument (OMI) -Aura- Near-UV aerosol product OMAERUV dataset. The algorithm determines the occurrence of Dust Aerosol Episode Days (DAEDs), whenever high loads of DA (higher than their climatological mean value plus two/four standard deviations for strong/extreme DAEDs) exist over extended areas (more than 30 pixels or 300,000 km2). The identified DAEDs are finally grouped into Dust Aerosol Episode Cases (DAECs), consisting of at least one DAED. According to the algorithm results, 166 (116 strong and 50 extreme) DAEDs occurred over the MB during the study period. DAEDs are observed mostly in spring (47%) and summer (38%), with strong DAEDs occurring primarily in spring and summer and extreme ones in spring. Decreasing, but not statistically significant, trends of the frequency, spatial extent and intensity of DAECs are revealed. Moreover, a total number of 98 DAECs was found, primarily in spring (46 DAECs) and secondarily in summer (36 DAECs). The seasonal distribution of the frequency of DAECs varies geographically, being highest in early spring over the eastern Mediterranean, in late spring over the central Mediterranean and in summer over the western MB.

Olive tree with its main final product, olive oil, is an important element of Mediterranean history, considered the emblematic fruit of a civilization. Despite its wide diffusion and economic and cultural importance, its evolutionary and phylogenetic history is still difficult to clarify. As part of the Mediterranean basin, Algeria was indicated as a secondary diversification center. However, genetic characterization studies from Maghreb area, are currently underrepresented. In this context, we characterized 119 endemic Algerian accessions by using 12 microsatellite markers with the main goal to evaluate the genetic diversity and population structure. In order to provide new insights about the history of olive diversification events in the Central-Western Mediterranean basin, we included and analyzed a sample of 103 Italian accessions from Sicily and, a set of molecular profiles of cultivars from the Central-Western Mediterranean area. The phylogenetic investigation let us to evaluate genetic relationships among Central-Mediterranean basin olive germplasm, highlight new synonymy cases to support the importance of vegetative propagation in the cultivated olive diffusion and consolidate the hypothesis of more recent admixture events occurrence. This work provided new information about Algerian germplasm biodiversity and contributed to clarify olive diversification process.
