Do tourists disperse weed seed? A global review of unintentional human-mediated terrestrial seed dispersal on clothing,vehicles and horses

Human-mediated seed dispersal is recognised as an important, but under-researched, issue. To assess the potential for tourists to act as unintentional seed dispersal agents, we reviewed published and unpublished data on seed dispersal via clothing, vehicles (cars) and in/on horses and donkeys, all of which can be used by tourists. Seeds from 754 species of terrestrial plants have been collected from these vectors, 15% of which are internationally recognised environmental weeds. Seeds were collected from personal clothing and equipment (228 species), the fur of donkeys and horses (42 species), horse dung (216 species) and vehicles (505 species). Most were herbs (429 species) or graminoids (237 species) and native to Europe. Annual Poa, White Clover, Kentucky Bluegrass and Yorkshire Fog were the most frequent species. There have been eight studies specifically on tourists, which identified 12 species on clothing, 26 on vehicles and 133 from horse dung. Methods that minimise the risk of tourists as human-mediated dispersal agents may therefore be appropriate for some tourism activities/destinations: suggestions are made. Further sampling using standardised experimental techniques is required to assess the relative risk associated with specific tourist activities and locations and determine which, and how much, seed is transported.

The power of video to trigger innovation: rice processing in central Benin

Participatory plant breeding began in developing countries and now some European farmers and scientists are proposing its suitability in contributing to sustainable agriculture. This paper uses both genetics and sociology to determine the conditions required. A review of the sustainability of projects implemented in developing countries initiated discussion of an organic durum wheat participatory breeding programme, which is currently being implemented in the south of France. The analysis highlighted the need for the critical participation of experts from different horizons in a socio-technical network. Multi-level interactions and cross-linked learning processes about breeding methods and sociological concepts are needed for effective communication between different stakeholders and scientific disciplines. This approach enables implementation of a range of different action systems in which the production of relevant knowledge and rules addresses the issue of the sustainable development of diverse agro-food systems, rather than the generalization of one model.
