Do your efforts engage and impact local custodians of agrobiodiversity?
We are happy to pass on this request from Simran Sethi. Do get in touch with her, you wont regret it.
I am an environmental journalist focusing on the loss of biodiversity in our food system. This erosion of agrobiodiversity echoes through every part of our food system. It strips soil, seed, pollinators, crops, livestock and aquatic life of their ability to adapt to changes in the environment—and puts our entire food supply at risk.
This extinction of food is a process, not a singular event. It is buried in the soil, hidden within feedlots and immersed in the ocean. I addressed some of this in my recent TEDx talk on seeds as the buried foundations of food, but seek to highlight this issue more broadly in my upcoming book “Endangered Food: The Erosion of What and How We Eat.” Because eating is both an agricultural and cultural act, my narrative is focused on conservation through consumption; specifically, on efforts to save foods by eating them.
And this is where I seek your assistance. I recognize this issue is complex and that consumption presents its own set of challenges. As those intimately involved in biodiversity preservation, you have firsthand knowledge of the ways in which your efforts engage and impact custodian farmers and local communities. Food is the embodied history and cultural identity through which the public can understand and address the global challenge of genetic erosion. To that end, I welcome any case studies on the expansion of underutilized species (both on farms and in markets) and/or examples of eating as a compelling and delicious way to support biodiversity and reshape the future of food through lived experience.
I can be reached for any questions or comments on simran “at” simransethi.com. Thank you for your consideration.
Nibbles: Trees, Gates on CG, Gardens, NUS surveys, GMOs, Free range livestock, Tasty fish, Traditional potatoes
- Britain gets a tree seed bank. Wait, it didn’t already have one? St Helena seems to, sort of. And Cameroon. And why they’re needed more than ever; and more. Although in Brazil trees can be the bad guys.
- Bill Gates praises CIMMYT, and the CGIAR as a whole.
- A Renaissance garden recreated in NYC.
- A survey on moringa. And one on achocha and oca.
- And speaking of deconstructing weird crops, how about saffron?
- Yet another one of those GMOs-are-not-as-bad-as-you-think pieces. Is any of this getting through, I wonder?
- Free range pigs in Kenya and the USA.
- Speaking of free range livestock… Well, a species distantly related to livestock anyway. Oh, and here’s another restoration story, from another continent.
- Free range glass eels too. And salmon, after a fashion.
- Traditional potatoes in fancy Lima restaurants. Maybe with pork or fish?
Suha Ashtar RIP
Dr Devra Jarvis of Bioversity International, formerly the International Plant Genetic Resources Institute, reminisces about her late friend and colleague, Dr Suha Ashtar, on behalf of the global on-farm team.
It is with great sadness that we heard of the passing of Suha Ashtar on 17 April 2013 in Aleppo. Suha was one of the first members of the “in situ family” that over the years worked at Bioversity International to establish a scientific basis for on farm conservation of crop biodiversity, together with colleagues from Burkina Faso, Ethiopia, Hungary, Mexico, Morocco, Peru and Vietnam. I remember my first meeting with Suha, when we were interviewing for the various regional staff to help me coordinate the global in situ programme, and being impressed by her lively and bright manner and her ability to forcefully express her own ideas and opinions. I still remember a short trip into the Italian countryside the core in situ project group took in a mini-bus, together with our donor, and the heated discussions about how the project should go, not to mention the calls for me to drive more slowly, as the back of the bus was shaking back and forth! Going through some old photos, I found a lovely one of Suha at the group dinner of a global meeting we had in Pokhara, Nepal in 1999 with colleagues from over 20 countries about working to support farmers in the assessment, management and gaining benefits from the conservation and use of traditional crop varieties. The dinner had followed long discussions and a hike up the hills nearby to meet with some local women and men farmers’ groups. Suha will be sorely missed by her colleagues and friends, and by myself especially as one of her first supervisors, when she was just setting out, young, intelligent and full of energy to start her career.
Conserving Prunus africana?
I’ve been sitting on it for a while, but a paper which AoB Blog discussed back in January led me to uncover a whole load of stuff on Prunus africana. The African Cherry Tree does not rate a leaflet in the African Food Tree Species series, perhaps because it’s not a, well, food tree, but that doesn’t mean it’s not important.
Chemicals extracted from the tree’s bark are used in a range of pharmaceutical products to treat enlarged prostate (benign prostatic hyperplasia), an extremely common condition that affects up to half of men aged over 50.
Hence various efforts to develop sustainable harvesting methods. And also an interesting series of diversity and demographic studies:
- Phylogeography of the Afromontane Prunus africana reveals a former migration corridor between East and West African highlands: “The high genetic similarity found between western Uganda and west African populations indicates that a former Afromontane migration corridor may have existed through Equatorial Africa.”
- Structural diversity and regeneration of the endangered Prunus africana (Rosaceae) in Zimbabwe: “…poor regeneration, fewer P. africana trees in small and large size classes, dominance of positive height and diameter differentiation and high mingling.”
- Divergent pattern of nuclear genetic diversity across the range of the Afromontane Prunus africana mirrors variable climate of African highlands: “The observed patterns indicate divergent population history across the continent most likely associated to Pleistocene changes in climatic conditions. The high genetic similarity between populations of West Africa with population of East Africa west of the Eastern Rift Valley … provides further evidence for a historical migration route. Contrasting estimates of recent and historical gene flow indicate a shift of the main barrier to gene flow from the Lake Victoria basin to the Eastern Rift Valley…”
- Modelling the potential distribution of endangered Prunus africana (Hook.f.) Kalkm. in East Africa: “Prunus africana distribution is thus highly vulnerable to a warming climate and highlights the fact that both in-situ and ex-situ conservation will be a solution to global warming.”
Maybe we could do with some more seed behaviour data. But it would seem there is now plenty of diversity, demographic and sustainable harvesting information on which to base a comprehensive conservation strategy. Is someone coming up with one?
