A dataset comprising of the spatio-temporal dynamics of the diffusive spread of an agricultural package. The data is made up of radiocarbon data from 735 early Neolithic sites in Europe, the Near East and Anatolia.
“The Caloric Suitability Indices” (CSI) capture the variation in potential crop yield across the globe, as measured in calories per hectare per year. Moreover, in light of the expansion in the set of crops that are available for cultivation in the course of the Columbian Exchange, the CSI indices provide a distinct measure for caloric suitability for the pre-1500 and the post-1500 era.
The CSI indices provide four estimates of caloric suitability for each cell of size 5′× 5 in the world:
The maximum potential caloric yield attainable given the set of crops that are suitable for cultivation in the pre-1500 period.
The maximum potential caloric yield attainable, given the set of crops that are suitable for cultivation in the post-1500 period.
The average potential yields within each cell, attainable given the set of crops that are suitable for cultivation in the pre-1500 period.
The average potential yields within each cell, attainable given the set of crops that are suitable for cultivation in the post-1500 period.
The Caloric Suitability Indices (Galor and Özak, 2016) captures the potential agricultural output (measured in calories) based on crops that were available for cultivation in the Pre-1500CE and Post-1500CE eras. It is available for 5’ by 5’ grid cells and at the country level. The data can be used to assess or account for the exogenous effect of agricultural potential on various economic and social outcomes. The data can be used to assess or account for the exogenous effect of agricultural potential on various economic and social outcomes. An IPython notebook is included to show how it can be used and also compares it with another measure of agricultural suitability. The data is provided as a service to the academic research community (see license for permitted uses).
“The Human Mobility Index (HMI)” that estimates the potential minimum travel time across the globe (measured in hours) accounting for human biological constraints, as well as geographical and technological factors that determined travel time before the widespread use of steam power. In particular, the HMI indices provide a distinct measure of human mobility potential in different eras:
Human Mobility Index (HMI): Mobility on land without seafaring technology. Shows mobility potential on land before the widespread use of steam power.
Human Mobility Index with Seafaring: HMI expanded to allow mobility on a select set of seas for which historical data was available. Shows potential mobility on land and seas before the introduction of ocean-faring ships.
Human Mobility Index with Ocean: HMI expanded to allow mobility on all seas based on CLIWOC (interpolated). Shows potential mobility on land and seas after the introduction of ocean-faring ships, but before the widespread use of steamships.
Based on these cost surfaces, researchers can find the minimum travel times between locations or construct more sophisticated statistics based on these. For example, Ashraf, Galor and Özak (2010) construct measures of pre-historic geographical isolation to study the effect of isolation on development. Similarly, Özak (2010), Depetris-Chauvin and Özak (2016, 2020) and Michalopoulus and Özak (2019) construct potential trade and information flow networks among countries, ethnic groups, cities, and artificial geographical units, to study the origins of the division of labor, and the effect of technological change on isolation and development. Likewise, Depetris-Chauvin and Özak (2019) use these measures to construct artificial states based on Voronoi partitions.
This strategy overcomes the potential mismeasurement of distances generated by using geodesic distances (Özak 2010), for a period when travel time was the most important determinant of transportation costs. Additionally, it removes the potential concern that travel time to the frontier reflects a country’s stage of development, mitigating further possible endogeneity concerns. The research validates these measures by (i) analyzing their association with actual historical travel time; (ii) examining their explanatory power for the location of historical trade routes in the Old World; and (iii) analyzing their association with genetic and cultural distances.
“Iona is a site of exceptional historical, archaeological, and religious interest, and has been since its foundation as a monastery around AD 563. Despite the multiple ways in which Iona has been of interest to scholars and the general public, its complex legacy of place-names has never been the subject of sustained scholarly investigation.
“This project, funded by the AHRC, interrogates the dynamics of the namescape, the historical and changing landscape of names, of Iona and its environs, shedding light on its past and its complex present, and proposing new ways of curating place-names as part of heritage management.”
“There is significant arts and humanities research infrastructure in the UK, consisting of institutes, centres, hubs, research clusters and networks, and professional, learned and scholarly societies with a research focus. However, much of this infrastructure remains invisible, undiscoverable, and unconnected. This project seeks to identify and connect this complex research eco-system in the arts and humanities through the creation of an interactive, online, open access map. Along with a searchable database and application programming interface (API).”
“The sheer number of individual programmes means that creating a union catalogue at item level is not a viable option in the short or medium term. Instead, the Concert Programmes Project aims to create an online database of concert programme holdings in the UK and Ireland at collection level to enable scholars and music lovers to locate material that may be relevant to their research and and interests, and library professionals to identify priorities for collection development and preservation.”
“The Baudelaire Song Project researches and brings together for the first time all the song settings ever of Baudelaire’s poetry, looking at classical music and popular music settings, in French original and in translation, with music scores and in audio format.”
“SPACES OF HOPE: the Hidden History of Community Led Planning in the UK has explored the often-overlooked ways in which local people and organisations have come together to improve their physical and social environments. Since the 1960s a rich but hidden history has emerged of communities campaigning, drawing up their own land-use plans, owning, occupying and developing sites and initiating creative community projects. Bringing together universities, artists and archivists and working in partnership with the Town and Country Planning Association, SPACES OF HOPE: PEOPLES’ PLANS is an AHRC-funded research project that aims to reveal these histories and spark debate about how lessons can be applied to current community place-shaping.”
