- Mike Jackson wants to know how many crop varieties you can name. Please tell him. My number is 42.
- This is what CRISPR looks like. In an infographic, that is.
- Japan’s rice terraces were better for biodiversity when they were, you know, full of rice.
- A Wendell Berry biopic?
- Yep, more on eating insects. It’s definitely a thing now.
CCAFS tells the world how agriculture can adapt to climate change
The CGIAR Research Program on Climate Change, Agriculture and Food Security has prepared syntheses papers on two of the topics related to agriculture that are being considered by UNFCCC’s Subsidiary Body for Scientific and Technological Advice (SBSTA) in 2016. The topics have incredibly unwieldy and confusing titles. They boil down, I think, to agricultural practices, technologies and institutions to enhance productivity and resilience sustainably, but you can read all the subordinate clauses in the CCAFS blog post which announces the publication of their reports.
Of course, what we want to know here is whether crop diversity is adequately highlighted among the said practices, technologies and institutions. The answer is, as ever, kinda sorta. The following is from the info note associated with the first paper, “Agricultural practices and technologies to enhance food security, resilience and productivity in a sustainable manner: Messages to the SBSTA 44 agriculture workshops.”
Crop-specific innovations complement other practices that aim to improve crop production under climate change, e.g. soil management, agroforestry, and water management. Crop-specific innovations include breeding of more resilient crop varieties, diversification and intensification.
Examples include the Drought Tolerant Maize for Africa initiative, disease- and heat-resistant chickpea varieties in India, improved Brachiaria in Brazil, hardy crossbreeds of native sheep and goats in Kenya, as well as changes in the crops being grown, such as moves from potato into organic quinoa, milk and cheese, trout, and vegetables in the Peruvian highlands.
The other paper, “Adaptation measures in agricultural systems: Messages to the SBSTA 44 Agriculture Workshops,” focuses on structures, processes and institutions. I particularly liked the emphasis on the importance on indigenous knowledge and extension systems. But why no mention of genebanks? Especially as Bioversity’s Seeds of Needs Project was nicely featured as a case study in the first paper. Here, after all is a concrete example of institutions — national and international genebanks — linking up to farmers to deliver crop diversity in the service of adaptation.

- The origins of our diet. It’s the interactions, stupid.
- Barley as superfood. No, not the fermented kind.
- More diverse freshwaters give higher fish yields.
- European earthworm diversity mapped. No word on relationship with yields. Surprisingly difficult to see any correlation with agricultural intensification.
- It’s been a bad time for livestock (and therefore people) in Mongolia and in Ethiopia.

- Opportunities and Threats to Harmonisation of Plant Breeders’ Rights in Africa: ARIPO and SADC. While the intention of ARIPO and SADC is to create a single internal market for protected varieties in Africa, “the end result may look quite differently.”
- Evaluation of Resistance to Ralstonia solanacearum in Tomato Genetic Resources at Seedling Stage. Out of 285 varieties from 21 countries in the Korean genebank, 4 may be resistant to bacterial wilt.
- Following the Open-Source Trail Outside the Digital World: The Case of Open-Source Seeds. “…by not rejecting the idea of property, including intellectual property, but rather attempting to manage it differently, it creates its own enclosures.”
- Grain protein concentration and harvestable protein under future climate conditions. A study of 108 spring barley accessions. Higher CO2 and temperatures lead to higher protein concentrations but lower yields, so lower harvestable protein. The good news is that there’s variation in the response of varieties.
- How can we harness quantitative genetic variation in crop root systems for agricultural improvement? Apparently we still don’t have a mechanistic understanding of root growth, and we’ll need it if we’re going to improve function.
- Bambara Groundnut for Food Security in the Changing African Climate. It’s nutritious, it’s drought tolerant, and it can be intercropped. What’s not to like?
- Neutral and functional marker based genetic diversity in kodo millet (Paspalum scrobiculatum L.). Indian material falls into 4 groups, with Bihar being very diverse. African genepool and wild species should be useful in broadening base in India.
- Origin, Dispersal, and Current Global Distribution of Cacao Genetic Diversity. We’ve come to the limit of the usefulness of the Pound Collection.
- Exploring the role of local heirloom germplasm in expanding western Washington dry bean production. 24 bean varieties have been grown in the area for 20–130 years, representing a useful starting point for participatory plant breeding.
- Growing Cassava (Manihot esculenta) in Mato Grosso, Brazil: Genetic Diversity Conservation in Small–Scale Agriculture. Lots of diversity within communities, and differences among communities. Varieties with same name not necessarily genetically similar.
- Establishment of an in vitro propagation and transformation system of Balanites aegyptiaca. So?
- Mapping cropland-use intensity across Europe using MODIS NDVI time series. Four indicators show highest cropping intensity in Germany, Poland, and the eastern European Black Earth regions, and lowest in eastern Europe outside the Black Earth region. Interesting to mash this up with agricultural biodiversity? Like earthworms?
Building a prize-winning cassava house
We often say that crop diversity is the foundation of food security, but you have to actually build a house on a foundation, to get the full benefit. So it’s instructive occasionally to consider all the myriad other things that have to go right for crop diversity to have an impact, quite apart from breeding. And it’s great to see recognition for an organization that works on a number of those things: the Queen’s Anniversary Prize was just awarded to the UK’s University of Greenwich for the cassava work of the Natural Resources Institute, which includes everything from pest and disease control to processing and product development. Congratulations!
And if you still want to read something about how to use cassava diversity to provide the foundation for all that cool stuff NRI does, The Economist has you covered.
