Massive expectations for MOOC on climate change adaptation

UNDP, FAO and UNITAR have just announced a Massive Open Online Course (MOOC) on National Adaptation Plans Building Climate Resilience in Agriculture. It starts 13 November.

If you want to learn from development professionals currently engaged in national adaptation planning and agriculture, then this 6-week course is for you.

I opened the syllabus with trepidation, but it does look like the role of agricultural biodiversity will be addressed.

If any of our readers decides to take the course, we’d be happy to help them share their experiences here.

Nibbles: Millets galore, Human diversity & ag, Super farmers, Extinction is forever, Indian nutrition maps, Future Food competition, Banana viruses, Cassava in Brazil & Africa, Sugar book, Fairchild & Irma, Vegetable ROI, Embrapa beans, Certified coffee, Legal pot, Native American foods

Today’s new genome is pearl millet. The most climate-smart of crops? Now, to process it more easily.
Finger millet is not too bad either.
Agriculture was good for human diversity, at least in Papua New Guinea. Elsewhere, maybe not so much.
Julio Hancco Mamani grows 400 potato varieties up in the Andes (but how did it all start?). And Rahibai Soma Popere “15 varieties of rice, nine varieties of pigeon pea and sixty varieties of vegetables, besides many oil seeds” in Maharashtra.
“West Bengal government encourages cultivation of extinct rice varieties.” Wait, what?
Presumably not extinct like silphium.
India’s first nutrition atlas will maybe tells us where more Rahibai Soma Poperes are most needed.
Future Food includes seeds.
Cleaning up bananas.
Would love to have been on the “Brazilian Cassava Learning Journey.” Tanzania next?
The bitter side of sugar.
Fairchild Tropical Botanic Garden damaged by Irma.
Research on vegetables really pays off, vegetable researchers say.
Brazilian bean catalog launched.
Certifying coffee seeds.
Pot next?
Closely followed by Navajo tea.

Brainfood: Baobab nutrition, New wild cucumber, Strawberry diversity, Sahelian threats, MTAs, CC & yields

Nutritional variation in baobab (Adansonia digitata L.) fruit pulp and seeds based on Africa geographical regions. Malawi has the most nutritious types.
A valid name for the Xishuangbanna gourd, a cucumber with carotene-rich fruits. Cucumis sativus L. var. xishuangbannanensis Qi & Yuan ex S.S.Renner, var. nov., if you must know.
Population genetic analysis of a global collection of Fragaria vesca using microsatellite markers. The Icelandic are different from the other European populatons.
Spatially explicit multi-threat assessment of food tree species in Burkina Faso: A fine-scale approach. All species threatened everywhere, but especially by climate change.
Use and Misuse of Material Transfer Agreements: Lessons in Proportionality from Research, Repositories, and Litigation. Horses for courses.
Temperature increase reduces global yields of major crops in four independent estimates. “Without CO2 fertilization, effective adaptation, and genetic improvement, each degree-Celsius increase in global mean temperature would, on average, reduce global yields of wheat by 6.0%, rice by 3.2%, maize by 7.4%, and soybean by 3.1%.”

Brainfood: Eggplant germplasm, CC threat, Impact metrics, Drought & seeds, Burundi cattle, Wild chickpea, Banana collecting, Bambara groundnut diversity, CIP cryo, USA PGR policy, Australian forages, ILRI seed testing, Nepal intensification, Maize and CC

World Vegetable Center Eggplant Collection: Origin, Composition, Seed Dissemination and Utilization in Breeding. 3,200 accessions from 90 countries, covering all 3 cultivated species, but not enough wild relatives.
An integrated framework to identify wildlife populations under threat from climate change. Need to know about landscape connectivity, and genomic data would be useful too.
Research impact: a narrative review. There are lots of methods, and the indirect ones are sometimes the best.
Orthodox seeds and resurrection plants: two of a kind? Resurrection plants have reactivated the ancient seed drought tolerance program in vegetative tissues.
Effect of genetic European taurine ancestry on milk yield of Ankole-Holstein crossbred dairy cattle in mixed smallholders system of Burundi highlands. European ancestry good for milk yield.
First insights into the biochemical and molecular response to cold stress in Cicer microphyllum, a crop wild relative of chickpea (Cicer arietinum). High altitude Himalayan species found to have frost tolerance.
Banana Collecting Mission in the Autonomous Region Of Bougainville (AROB), Papua New Guinea. 13 days, 61 accessions. Hard work.
Morphological Characterisation of Selected African Accessions of Bambara Groundnut (Vigna subterranea (L.) Verdc.). 3 out of 300 out of 1973 have high yield potential. Hard work.
A large-scale viability assessment of the potato cryobank at the International Potato Center (CIP). They’re getting better at it. Hard work.
Deep Seeded Problems: A Look At Seed Bank Regulations. The USA should engage internationally on crop diversity conservation. Hard work.
Australian Pastures Genebank – Temperate Species Regeneration. Hard work.
Medium-term seed storage of 50 genera of forage legumes and evidence-based genebank monitoring intervals. Hard seeds are hard work.
Agricultural Land Use Intensity and Determinants in Different Agroecological Regions in Central Nepal Himalaya. Location, location, location.
Maize Diversity and Climate Change. To investigate the local adaptation of landraces, which you need for adaptation to climate change, you need the synergy that comes from genomics and phenomics in coordinated fashion.

Brainfood: Maize trifecta, Montado grazing, Indian CWR, Amazonian cassava, Better breeding, Australian CWR, Apple routes, Citrus routes, African chickens, Ancient African ag, Ancient Mayan ag

Genotyping-by-sequencing highlights original diversity patterns within a European collection of 1191 maize flint lines, as compared to the maize USDA genebank. “The joint analysis of collections by GBS offers opportunities for a global diversity analysis of maize inbred lines.”
Genetic Diversity among Selected Elite CIMMYT Maize Hybrids in East and Southern Africa. It could, and should, be more.
Genetic diversity and intra-racial structure of Chilean Choclero corn (Zea mays L.) germplasm revealed by simple sequence repeat markers (SSRs). There’s diversity within the race. More than in Europe or elite African hybrids? Er, well…
The effect of grazing exclusion over time on structure, biodiversity, and regeneration of high nature value farmland ecosystems in Europe. Both undergrazing and overgrazing are bad for the Portuguese montado.
Wild Relatives of Cultivated Plants in India. Huge book, much of it on Google Books.
Farmer variety exchange along Amazonian rivers influences the genetic structure of manioc maintained in a regional Brazilian GeneBank. No structure among the 5 main Amazonian rivers.

Reconstructing Asian faunal introductions to eastern Africa from multi-proxy biomolecular and archaeological datasets. Mid-first millennium CE, or 3000 BCE? For chickens and rats, the former.
