- Dietary diversity, food security, and development projects in low- and middle-income contexts: Findings from 24 countries. Development projects are most effective at improving dietary diversity and food security when they bring together agriculture, nutrition and local communities.
- Enhancing farmers’ access to neglected crop seeds for healthy diets in a changing climate: six recommendations for policy action. Improving farmers’ access to opportunity crop seeds requires coordinated action across seed systems, with researchers, policymakers, seed producers and farming communities all playing complementary roles.
- The effects of seed policies, laws and regulations on farmers’ ability to access and use diverse, locally adapted farmers’ varieties and landraces. Seed policies shape collaboration between farmers, communities and formal seed systems, and regulations can either enable or constrain the exchange of locally adapted varieties that keeps agricultural diversity alive.
- Studying vanishing dietary diversity before it is lost: the World Diet Initiative. The World Diet Initiative brings together nutrition science, ecology and cultural knowledge to understand disappearing food traditions, showing that protecting dietary diversity requires collaboration across disciplines and communities.
- The Spanish Network of Genetic Conservation Units: a cooperative tool for the conservation and sustainable use of forest genetic resources under a changing environment. The Spanish Network of Genetic Conservation Units show how sharing expertise and responsibilities can strengthen forest conservation.
- Strengthening national genebanks through genomics and regional collaboration: Lessons from Latin America and the Caribbean. A regional community of practice is helping national genebanks overcome technical and institutional barriers through shared genomic approaches, turning isolated collections into connected systems for conserving and using crop diversity.
Brainfood: Wild chickpea, Feral brassica, Peruvian cacao, Panamanian cacao, Tree diversity, Healthy diets in PNG
- Genome-wide molecular diversity analyses identify wild Cicer as reservoirs of variations for chickpea improvement. Wild relatives of chickpea harbour a wealth of genetic variation that has yet to be exploited by breeders. But it’s mainly within species.
- Genetic and Morphological Diversity in Spontaneous Populations of Brassica rapa: How Do Feral Populations Differ From Wild Ones? When a crop escapes cultivation, does it become wild again? Apparently not. Pity.
- Genetic structure of traditional cacao reveals four new genetic lineages in indigenous Amazonian sites in Peru. Genetic analysis of traditional cacao maintained by Indigenous communities in the Peruvian Amazon uncovers four previously undescribed genetic lineages.
- Contrasting germplasm composition and propagation practices in the two major cacao-growing areas in Panama. Two of Panama’s principal cacao-growing regions have developed markedly different genetic profiles, reflecting both the varieties farmers cultivate and how they propagate them. I think they have been previously described though.
- Ecological multifunctionality of watersheds increases with tree species richness. Watersheds planted with a greater diversity of tree species perform better across multiple ecological functions simultaneously, including nutrient cycling, soil protection and water regulation.
- Nutrition sensitive poverty and its correlates in Papua New Guinea: incorporating healthy diet targets into poverty measurement. Conventional poverty measures ask whether people can afford basic necessities. Why not ask a more demanding question: can they afford a healthy diet? Hopefully meaning a diverse one.
Nibbles: Cayman coconuts, Wild beans, Breeding Bambara, Aussie genebank, UAE law, EBI, Amazonian ag
- The Cayman Islands bets on a genebank of coconut diversity.
- The Alliance of Bioversity & CIAT’s genebank bets on growth cabinets to save picky wild bean.
- IITA bets on stakeholders to build a better Bambara groundnut. And its genebank, presumably.
- The Australian Seed Bank Partnership bets on, well, seeds.
- The UAE bets on a PGRFA law.
- Ethiopia bet on a national genebank 50 years ago.
- People have been betting on the chagra in the Amazon for 4,500 years.
Brainfood: Seeds through time
- Natufian sickle blades (ca. 15,000–11,700 cal. BP) reveal cereal cultivation ca. 4.5 millennia before domestication. Archaeological evidence from ancient sickle blades suggests that people were harvesting cereal seeds thousands of years before domesticated forms emerged, blurring the line between foraging and farming, and offering fresh insight into the long co-evolution of humans and crops.
- Teosinte alleles enhance nitrogen assimilation and seed protein in maize. Wild relatives continue to provide valuable genetic resources for the improvement of crop seeds.
- Modeling seed germination data to meet biodiversity conservation needs in the Mediterranean. Robust germination models can improve both restoration planning and ex situ conservation by predicting when and how seeds are most likely to establish.
- To grow or not to grow: questioning seed dormancy and thermal germination responses along elevational gradients in four plant taxa. Seed dormancy does not always follow predictable patterns across environmental gradients.
- Delayed Seed Germination as a Strategy to Cope With Environmental Stress and Disturbance. Seed dormancy follows a (fairly) predictable pattern when you look at stress and disturbance.
- Reconsidering how to dry orthodox seeds for improved ex situ conservation outcomes. Conventional wisdom about drying orthodox seeds before storage may deserve re-evaluation, and refining drying protocols could enhance long-term viability and strengthen the effectiveness of seed banks.
- Short periods dominate mast seeding across diverse tree species. A broad analysis of mast seeding reveals that many tree species synchronize seed production over relatively short recurring intervals rather than highly irregular cycles.
Brainfood: Diversity of Oats, Cotton, Sugarcane, Rice, Amaranthus, Vegetables, Agroforestry, Value chains
- Genome-wide comparative diversity uncovers population structure, global distribution, and targets of selection in hexaploid oat. A worldwide survey reveals how oat diversity is structured, spread, and shaped by breeding, helping pinpoint untapped genetic resources for future improvement.
- Genomic diversity and the domestication history of cotton (Gossypium hirsutum). Its genome traces cotton’s journey from its wild origins in Mesoamerica while documenting the genetic narrowing that accompanied domestication.
- Genetic architecture of sugarcane traits in a polyploid genomics framework. New genomic tools finally begin to untangle the diversity of one of agriculture’s most genetically complex crops, exposing the basis of traits breeders have long selected largely in the dark.
- Projected warming will exceed the long-term thermal limits of rice cultivation. Rice has historically thrived within remarkably stable climatic boundaries. Those boundaries are now on course to be crossed across major growing regions, with profound implications for global food security. Diversity to the rescue?
- An inter-specific Amaranthus pangenome captures genetic variation potentially underlying key leafy vegetable traits in this underutilised crop. A rich reservoir of previously hidden diversity emerges from across multiple cultivated amaranths, offering breeders new options for improving a neglected but nutritious vegetable.
- Impact of gardening and nutrition support provided to women in refugee camps in Cox’s Bazar, Bangladesh. Even in one of the world’s most challenging humanitarian settings, greater interspecific crop diversity translated into better diets, improved food security, and enhanced wellbeing.
- Designing perennial crop-based agroforestry systems: specificities, challenges, and opportunities. Diversification does not stop at the field edge: how perennial crops can be combined with trees to deliver productive, resilient, and biodiversity-friendly farming systems.
- Towards Nature Positive supply chains: From biodiversity commitments to organisational action. What would it take to move biodiversity from corporate promises to business practice? Maybe the above examples can help turn aspiration into measurable action.
