Remembering Dorothy Tamasia, barefoot banana curator of the Solomon Islands
Some bad news from Tony Jansen, via Facebook. He has kindly given us permission to reproduce his post here. This comes after more sad news from the Pacific just a few weeks ago.
I’m very sad to hear the tragic news that my very good friend Dorothy Tamasia has died. I dont know the hows or whats, only that she was too young. She was the true embodiment of the barefoot curator and lived out her life in very basic conditions with her people in the highlands of central Makira and passionately collected, protected and shared across her island and throughout the Solomon Islands over 108 varieties of bananas that she took part in collecting with Kastom Gaden Association. She was trained in morphological descriptors and management of germplasm collections despite having little formal education. Her work in documenting and maintaining her banana collection led to Solomon Islands being recognised as holding one of the largest remaining and least documented collection of banana diversity in the world – and she was a leading figure in a revival in banana diversity and its cultural connections in Makira through diversity fairs and other events.
Banana is the staple food in Makira. Dorothy was a hero for conservation in use of plant genetic resources and she dedicated much of her too short life to that purpose. She took part in pioneering work to test and promote high vitamin A fei banana varieties. A poster from that work can be seen here and she was part of banana diversity work supported variously by ACIAR, the SPC Centre for Pacific Crops and Trees (CePaCT) and Seed Savers Network.
I last saw her in late 2011 after making the 4 hour walk to her village from the coast — which has no roads and is one of the most remote parts of a remote country. She was happy, and had recently started a bush early-childhood pre-school in a leaf house in a remote riverside location where she lived on her own with her children. The room was full of brightly coloured creations from nearby village children who came to her school — and surrounded by her bananas and her cacao farm. She was excited to be studying early childhood education. She was also busy duplicating, on her own, the banana collection she had maintained for almost a decade — back breaking work with no reward other than the custodianship that she treasured. She had a deep grasp of the issues including the controversy around crop genetic resources. She chose to keep above all of it and just continue her humble work that she knew was the right thing and a useful thing to do.
Dorothy was a beautiful person and a kind hearted and generous soul. I hope that in her death her life work and commitment to the Solomon Islands indigenous plant genetic resources and to food security for her people will be acknowledged and that the collections she had maintained will be supported to continue.
Speaking truth to power
And much good does it do.

Vavilov all over
Just a quick reminder that the BBC’s wonderful From Roots to Riches programme, charting the history of botany, tackles Nikolai Vavilov today. Coincidentally, one of Vavilov’s stamping grounds, Central Asia, has been featuring prominently at the 2014 Festival of Fruit, on now in Portland. Megan Lynch has been tweeting the hell out of it. Well worth following.

Brainfood: Luffa diversity, Pyrennean landraces, Sorghum diversity, Eucalypt diversity, French wheat, Genomic breeding, Hotspots, Protected areas, Apple diversity
- Population structure and diversity in cultivated and wild Luffa species. Luffa hermaphrodita is the closest wild species.
- Factors Enhancing Landrace in Situ Conservation in Home Gardens and Fields in Vall de Gósol, Catalan Pyrenees, Iberian Peninsula. It’s not just about landrace performance.
- Sorghum Genetic Resources: Conservation and Diversity Assessment for Enhanced Utilization in Sorghum Improvement. 236,000 accessions, 38,000 at ICRISAT alone, of which 3 have proved useful. Wait, what?
- Genetic Diversity in Eucalypts. It’s high, and needs to be used.
- Explaining the decrease in the genetic diversity of wheat in France over the 20th century. Because breeding.
- Animal-breeding schemes using genomic information need breeding plans designed to maximise long-term genetic gains. You can’t just wing it.
- Remaining natural vegetation in the global biodiversity hotspots. 15%, and fragmented.
- Targeting Global Protected Area Expansion for Imperiled Biodiversity. Increasing protected area coverage to Aichi targets would do little to achieve threatened species coverage in situ, at least for vertebrates.
- Phenotypic evaluation and characterization of a collection of Malus species. German apple collection characterized the old school way, and none the worse for that.
