The present paper synthesizes the main concepts inherent to landscape multifunctionality, highlights the importance of their multiple functions in the structuring of the territories, and focuses the key role played by land use/land cover changes as "driving forces" of landscape transformation dynamics. The methodological approach consisted in the analysis of land use, between 1990 and 2007, in the "dairy region" of Entre-Douro-e-Minho, located in the Northwestern Portugal and around the Porto

... tropolitan Area. This area has a high agricultural potential, and is characterized by its intensive and mechanized farming, specialized in milk production, and by a high concentration of farms, and by the existence of a competitive and dynamic agri-food industry. Abstract Pacific Island countries are spread over a vast area of the Pacific Ocean, occupying an area over 30 million km2. Smallness, remoteness and vulnerability are the major problems affecting the 22 Pacific Island Countries and Territories. The Pacific Island countries are particularly vulnerable to the impacts of global warming. Among other issues they are exposed to more intense natural hazards, such as tropical cyclones, extreme flood events, and droughts that easily can lead to disasters. In a recent report, the UN Food and Agriculture Organization alerted that such disasters can severely reduce food production in Pacific island nations and called for urgent measures to adapt to expected losses (FAO, 2008). In Social Science ideas about vulnerability to natural disasters have emerged in the past three decades following Amartya Sen's publication on famine (Sen CADERNOS CURSO DE DOUTORAMENTO EM GEOGRAFIA FLUP I 2013 60 disaster risk management / reduction into national policies, strategies, programs and budgets. This paper looks into the patterns of livelihood and food security and how it is affected by extreme flood events in Nadi, a tourist town in western Viti Levu of Fiji Islands. The question is if emigrations/ resettlement in particular cases are feasible options, e.g. for places like Nadi or even whole nations such as Kiribati or Tuvalu. This paper is a small summary of my PhD project's pilot case study area, Nadi in Fiji Islands. The aim of the paper is to show systematically, how vulnerable can Nadi Area become during and after an extreme flood event. The final PhD thesis research question is to analysing extreme flood events and their impacts on livelihood and food security in Nadi area in Fiji.
