Crop genetic erosion: understanding and responding to loss of crop diversity
https://hdl.handle.net/10568/115281
Abstract
Crop diversity underpins the productivity, resilience, and adaptive capacity of agriculture. Loss of this diversity, termed crop genetic erosion, is therefore concerning. While alarms regarding evident declines in crop diversity have been raised for over a century, the magnitude, trajectory, drivers, and significance of these losses remain insufficiently understood. We outline the various definitions, measurements…

Greenhouse gas emissions from cattle dung depositions in two Urochloa forage fields with contrasting biological nitrification inhibition (BNI) capacity
https://hdl.handle.net/10568/115387
Abstract
Grazing-based production systems are a source of soil greenhouse gas (GHG) emissions triggered by excreta depositions. The adoption of Urochloa forages (formerly known as Brachiaria) with biological nitrification inhibition (BNI) capacity is a promising alternative to reduce nitrous oxide (N2O) emissions from excreta patches. However, how…

Characterization of phytoene synthases from cassava and their involvement in abiotic stress-mediated responses
https://hdl.handle.net/10568/115388
Abstract
Abiotic stress stimuli induce the increased synthesis of abscisic acid (ABA), which is generated through the cleavage of xanthophyll precursors. To cope with the increased xanthophyll demand, maize and rice contain a third stress-induced gene copy, coding for phytoene synthase (PSY), which catalyzes the first carotenoid-specific reaction in the pathway. To investigate whether this…

Soil recovery of alluvial gold mine spoils in the Peruvian Amazon using Stylosanthes guianensis, a promising cover crop
https://hdl.handle.net/10568/115589
Abstract
The Amazon is an important reservoir of biodiversity and carbon but it is under pressure by multiple threats such as artisanal and small-scale gold mining (ASGM). In Peru ASGM has degraded 90,000 ha of old growth forest since the eighties, leaving vast areas as wastelands. As most ASGM in the region is illegal, efforts to recover degraded areas have been scant. Here we…

Using seminatural and simulated habitats for seed germination ecology of banana wild relatives
https://hdl.handle.net/10568/115683
Abstract
Ecologically meaningful seed germination experiments are constrained by access to seeds and relevant environments for testing at the same time. This is particularly the case when research is carried out far from the native area of the studied species. Here, we demonstrate an alternative—the use of glasshouses in botanic gardens as simulated-natural habitats to extend the ecological interpretation…

Varietal threat index for monitoring crop diversity on farms in five agro-ecological regions in India
https://hdl.handle.net/10568/115711
Abstract
Our knowledge about the status of agrobiodiversity on farms is still very limited. While several studies to assess the crop genetic diversity on farms have been undertaken, there are no systematic documentation and monitoring practices for varietal diversity in space and time. Achieve ment of the agrobiodiversity Aichi Target 13, established under the Biodiversity Strategy Plan 2011–2020,…

Has continued exposure to banana Xanthomonas Wilt worsened farmers’ welfare over time? Evidence from banana-producing households in Uganda
https://hdl.handle.net/10568/115828
Abstract
The livelihoods of millions of banana-farming households have been affected by Banana Xanthomonas Wilt (BXW) in Uganda for nearly two decades. The disease has no known cure, all banana cultivars grown are susceptible to it and it is endemic in all banana-producing regions in the country. This study analysed the long-term impact of the disease on the…

CONTEXT
The Greater Mekong Subregion has been undergoing rapid agricultural transformation over the last decades, as traditional diverse subsistence-oriented agriculture is evolving towards intensified commercial production systems. Negative environmental impacts often include deforestation, nutrient pollution, and…

Conservation status assessment of banana crop wild relatives using species distribution modelling
https://hdl.handle.net/10568/115913
Abstract
Aim: Crop wild relatives (CWR) are an essential source of genetic material for the improvement of certain traits in related crop species. Despite their importance, increasing public, scientific and political support, large gaps exist in the amount of genetic material collected and conserved of many CWR. Here, we construct a dataset on the distribution of wild banana species (Musa spp.) and…

Abstract
Urochloa (including Brachiaria, Megathyrus and some Panicum) tropical grasses are native to Africa and are now, after selection and breeding, planted worldwide, particularly in South America, as important forages with huge potential for further sustainable improvement and conservation of grasslands. We aimed to develop an optimized approach to…
