In the period from April 2019 to March 2020, the project leader (Matthews) visited Bangladesh, India and Thailand for work related to the project.
In collaboration with Dr Md. Anwar Hossain of Bangladesh Agriculture University (BAU), wild taro samples collected by us in 2018 are now being analysed using the same loci studied in other wild populations surveyed in the Philippines, southern China, Taiwan, and Vietnam.
A survey of wild taro populations in and around Bangkok city, in Thailand, was also carried out in collaboration with Dr Duangchai Sookchaloem of Kasetsart University. Leaf samples were collected from across the delta of the Chao Praya river that runs through Bangkok.

In FY 2018 year Dr Matthews joined counterparts in Bangladesh, China and Vietnam for expeditions to Sylhet, Yunnan, and Hue vicinity. He was also able to carry out a brief pilot survey of wild taro populations in the Chao Praya delta area of Thailand, in the vicinity of Bangkok city. RA Etsuko Tabuchi and Dr Matthews visited the Ethnobotany Laboratory of Dr Chunlin Long, at Minzu University, and prepared DNA samples for analysis with the help of his students. The sequences obtained for three chloroplast loci (ACE16, ACE26, ACE39) and one nuclear genome locus (PhyC) are now being analysed.
A combined field report for the field surveys in Bangladesh and Thailand is planned (these surveys were supported by a JSPS grant to Tsukuba University in collaboration with Dr K. Watanabe).

In the period April 2017 to March 2018, PJM was able to visit China, India, Thailand, and Vietnam for fieldwork and research discussions.
The main fieldwork areas were Mekong and Red River deltas, Vietnam, and a transect from Guilin to Guangzhou along a tributary of the Pearl River, China.
Wild taro populations were common in each of these river areas, but in each case there were important differences in ecology and uses. From Guilin to Guangzhou, we may have crossed a northern limit for the natural spread of taro, as it is in this region that the winter frost line marks the boundary between tropical and temperate vegetation zones.
Samples collected will be analysed in collaboration with Dr Nguyen Van Dzu (Department of Ethnobotany, Institute for Ecology and Biological Resources, Hanoi) and Dr Chunlin Long (Ethnobotany Laboratory, Minzu University, Beijing).

Fieldwork takes many forms... sometimes it is what we see while on holiday, while visiting another country for a meeting, or while walking near our own home, wherever that may be.
And sometimes - if we are lucky - it is actual funded fieldwork.
The last kind is best for focused observation in a particular area and time, for an ethnographic, ecological, or other field science study. The other kinds are nevertheless useful, for serendipitous discovery, for thinking, and for discussion.
In this project blog, we can report on all kinds of fieldwork, in relation to the subject of taro, and wild taro especially. Recently (2016-2018), I have travelled in China, India, and Vietnam.
I will say more about these trips as time permits.
