Most outdoor plants in Hungarian horticulture are exotas mainly from Middle and East Asia and North America. The flora of China is diversified and has many species because the last glacial period did not reach China. The richness of the Chinese flora was known for Europeans by the missionaries and medics first in 19th cectury. Later some bigger nurseries sent expeditions in China to collect new plants. Nowadays the Hungarian landscape architecture is impossible without Chinese plants.

Le présent document constitue un rapport final de l’étude dont l’objectif peut s’énoncer comme suit : « les zones portuaires peuvent elles être des nurseries de sars ? ». Tenter de répondre à cette question, simple en apparence, nécessite de mener des études aux niveaux populationnel et individuel et ce afin de comprendre les processus sous-jacents. Quatre volets ont été menés. Dans le premier volet, à partir des données issues du projet Nappex, nous avons étudié les changements spatio-temporels d’abondance de quatre espèces de sars dans cinq marinas réparties le long de la façade Méditerranéenne. Dans un second volet, nous avons cherché à comparer les cinétiques de mortalité post-installation de deux espèces de sars en milieu portuaire et naturel. Dans un troisième volet, la croissance et la condition de deux mêmes espèces de sars ont été comparées entre des zones portuaires et des zones naturelles. Enfin, dans un quatrième volet, nous avons cherché à mettre en place des outils pour appréhender la migration des juvéniles des zones portuaires vers les zones naturelles pour rejoindre les populations adultes.

Australian horticulture (fruit and vegetable production) relies upon a seasonal harvest workforce, much of which now consists of temporary migrant workers. This article argues that the composition of this workforce and the character of the work lead towards layered vulnerability, some groups being more exposed to low pay and substandard working conditions than others. Formally at least, employment conditions are generally protected by the federal Horticulture Award (2010). But are decent employment standards consistently observed? The article explores this question, examining three issues. First, does analysis of workforce composition reveal different tiers in the workforce, some more vulnerable than others? Second, do the casual nature of harvest work and the job search processes used by temporary migrant workers create disadvantaged groups? Third, does evidence about pay, working hours and work intensity reveal some workers to be more vulnerable than others? The article concludes with an examination of those factors that appear to be associated with layered vulnerability in the harvest workforce, and considers some policy implications.

Over recent decades, developments in network governance have seen governments around the world cede considerable authority and responsibility to commercial migration intermediaries for recruiting and managing temporary migrant labour. Correspondingly, a by-product of network governance has been the emergence of soft employment regulation in which voluntary codes of conduct supplement hard (enforceable) legal employment standards. This paper explores these developments in the context of temporary migrant workers employed in Australian horticulture. First the paper analyses the growing use of temporary migrant labour in this industry. It then describes how different types of intermediaries interact with this workforce. The paper then outlines both hard and soft employment regulations, and contrasts them with actual employment conditions, questioning how a network governance approach has affected this vulnerable workforce. The paper concludes that changes in network governance of migration and employment relations have emasculated formal legal regulation, leaving market forces to operate without effective or ethical constraints at the expense of the public good.
