Early Rice Project symposium last week

Last week we hosted in London a symposium for the Early Rice Project, 

Investigating the evolution and impact of rice cultivation through the later prehistory of monsoon Asia. We brought in colleagues and collaborators on the archaeology of India, Southeast Asia and China, from countries across several continents, and had a success full exchange, not just on the archaeobotany of the region and new data (much of it generated at UCL through our NERC and ERC projects), but also on the stories of domesaticated fauna, our current understanding of Neolithic spread processes, Mesolithic persistence, demographic growth and the emergence of complex societies and irrigation. What is clear is that there is much new to say about rice, when it first arrived in several regions of monsoon Asia, and as it was transformed into the cornerstone species in the subsistence base of large complex societies. Nevertheless the meeting highlighted also the major gaps in empirical evidence, both geographically and chronologically. We hope to be able to pull this together for publication to further broaden out our dialogue on what we know and what we need to know. There has certainly been a rapid increase in data as the chart (below) of published, or recently counted archaeological spikelet bases indicates (from my introduction presentation)..

Some recent outputs from the Early Rice Project include publication of ancient DNA from charred rice grains from sites in Thailand and India (Castillo, Tanaka et al.), which add some flesh on the skeleton of the Proto-indica hypothesis; and publication of the first of a new generation spatial modelling of the early geography of rice, this one aimed at deducing the most like region (or regions) from which rice originated and spread, in particular the originals of early japonica rice that was so important to the Neolithic developments in China and throughout Southeast Asia (Silva et al. in PLOSone).  See also, the paper on phytoliths as a reflection of weed flora (Weisskopf et al 2014), the first of several in the pipeline that will illustrate new and more robust approaches to determining past rice ecology.
