This paper presents an analysis of the social actors networking towards the feasibility of using native biodiversity for food production based on an empirical study conducted in South Brazil. Specifically, the North Coast Region has had a series of environmental problems resulting in conflicts on the use of resources. The search for solutions and public debate brought together farmers’ organizations, social movements, NGOs, government agencies, and academic groups. Recently, some of these actors established a common platform to raise food production based on native species of fruits giving rise to the ‘agrobiodiversity network’ in part by the activation of pre-existing networks but also requiring the entry of new players. On the other hand, forming agreements between different actors to consolidate the network has been difficult especially about the issue of rules that limit the access to native species and those that regulate food processing. The analysis has shown that the involved actors are amplifying the dialogues and collective learning processes thus building a common ground and shared beliefs.

AbstractAny assessment of whether or not Saccharum species are native or introduced in New Guinea require an evolutionary (in a geological sense), geophysical and climatological assessment of the island. Like many of the land masses circling the Pacific (in the volcanically active region known as the ‘ring of fire’) New Guinea is geologically young, with the island in its modern form not pre-dating 2 Ma. Novel modelling of the 74 ka youngest Toba supereruption indicates a potential extinction level tsunami and loss of habitat. The late Pleistocene megafaunal mass extinction and the last glacial maximum (33–16 ka) are two global effects that would have significantly altered the flora on New Guinea; though the implications of these events on New Guinea have not previously been studied. Even if the genus Saccharum was established on the island during pre-historic times the consequences of Toba and other global climate change events means that it would have been eliminated from New Guinea and would have had to be re-introduced during the period of human colonization. Indeed, given the evolution of Saccharum’s immediate ancestors in Africa and Indochina it is most parsimonious to conclude that it was never native to New Guinea, but was introduced by humans relatively recently.Little work has been done on palaeotsunami evidence and ancient tsunami modelling in New Guinea. However, the recent recognition that the Aitape skull (dating to about 6 ka) may have been the victim of a tsunami (Goff et al. 2017) show that, in the past, tsunami have pen etrated significantly (about 10 km in this case) into the interior of the island to have a profound effect on biodiversity. This tsunami would have left the north coast of the island impoverished of plant life for several decades after.
