  Citation × Citation Citation Abstract Copy Title: Aquaculture and Food Security - Can Fish Farming Fill the Gap? Author: Troell, Max While aquaculture has provided economic and nutritional benefits to millions, there are concerns that unconstrained sector expansion and intensification, coupled with its ecological and social impacts, globalization of markets, and climate change, may have undesirable impacts on the resilience of social-ecological systems. A significant part of the aquaculture expansion is expected to occur in coastal areas, where it directly affects resource systems already experiencing large pressure from human activities. Thus, there is a risk that the anticipated benefits from aquaculture may come at the expense of increased pressure on coastal ecosystem services, thus jeopardizing coastal people’s food security and livelihoods. Further, intensification may also indirectly increase the dependence on marine ecosystems through usage of fish resources as feeds. The practice of intensive farming of fish and crustaceans is characterised by inputs of high quality resources and energy and release of effluents. The industry continues to improve performance through research on food development and system designs, and recent initiative, the “Aquaculture dialogue”, attempts to identify sustainability criteria for a selection of cultured species. In addition FAO have recently moved beyond their earlier established “code of conducts” and are now developing a broader systematic perspective on aquaculture, i.e. “Ecosystem approach to aquaculture”. This presentation will discuss how aquaculture may impact on social-ecological resilience, more broadly and also in connection to coastal aquaculture development, and specifically considers the intensification of production methods. In connection to this some recent sustainability tools/indicators will briefly be discussed out from this perspective. Title: Aquaculture and Food Security - Can Fish Farming Fill the Gap?

  Citation × Citation Citation Abstract Copy Title: Impact of a marine protected area to fishery profitability and income distribution. Some evidence from the Gulf of Thailand (Mu Ko Chumphon National Park versus Chumphon Province) Author: Weigel, Jean-Yves, Noel, Jean-Francois, Morand, Pierre, Guillotreau, Patrice, Mawongwai, Thunthada Methodological difficulties, particularly when multifleet-multispecies fisheries are active, explain pro parte a weak research effort on the socio-economic impact of fishery activities after the implementation of a marine protected area. Two components of the socio-economic impact have been prioritized: the fishing unit profitability and the fishery household income distribution by comparing a marine protected area (Mu Ko Chumpon National Park) and an unprotected area (Chumphon Province) in Thailand. One can distinguish three phases: a bibliographical analysis, the carrying out of fishers village monographs and of a sample-based survey of fishery households. The sampling unit was the fishery household forming one or several fishing units defined by a métier (an association of a fleet, a main fishing gear, target species): 126 households forming 225 fishing units have been surveyed. The positive impact of the MPA on fishery profitability is shown by a principal component analysis which indicates that there is a lower proportion of fishing units harvesting inside or in adjacent areas of the MPA (insiders who are benefitting from implicit access rights) which face negative profit than those fishing remote from the MPA but in Chumphon Province (outsiders). This positive impact is confirmed by the performance of Chi-square tests: the insiders have relatively higher profit per fishing day than outsiders and Chi-square tests show a greater homogeneity of profits per fishing day and a lower variability for the insiders. A steady social impact from the MPA on fishery income distribution is revealed by the measure of concentration using an Herfindhal index and Lorenz curves which show the more egalitarian structure of insiders regarding the operating profit and the income per fishery household.
