Abstract: Dietary behaviours and practices: Determinants, action, outcomes Although public policies have for many years spearheaded information campaigns about how eating affects health, rising obesity rates show that the expected effects have yet to be achieved. Why consumers do not practically comply with nutritional recommendations? This question lead the ministry in charge of Agriculture, Food and Fisheries to require in 2010 an updated state of knowledge for peer-reviewed literature and to commission INRA to undertake a collective scientific expertise on dietary behaviours. The aim was to investigate the multiple determinants of behaviours and how behaviours form and change in individuals according to social class and age, but also collectively over a long period of time.

Mielke","doi":"10.1051/OCL.2012.0470","DOIUrl":"https://doi.org/10.1051/OCL.2012.0470","url":null,"abstract":"In a globalised world, the trade of goods and services constitute the heart of the economic system. But the trade patterns may show extreme diversity depending upon the nature of the concerned products. The technical and functional constraints do impose their laws, particularly when they relate to biological products/commodities. The term globalization is generally used to describe a complex process of international integration. When referring to oilseeds, the term must also relate to agriculture and human nutritional requirements for a rising human population spread all over the world, particularly in large urban environment.With an annual harvest of about 450 Mn T, oilseeds are naturally “globalized” in their production patterns. The complexity of their production schemes associated with the diversity of their usage on widespread geographical regions gives this group of commodities a unique role on the world markets. This process of opened trade channels has enabled the sector to meet the supply requirements of a quickly rising demand coming from both the population and all the industrial usages including alternative “green” energy.However, for the time being, demand growth has not been fully counter-balanced by production growth. As a consequence, unless some strict reallocation of acreage is effectively organized or new high yielding technologies are developed, it is a fact that vegetable oil will keep a strong demand base for a long time, compounded by the mechanical demand from economic growth in highly populated emerging economies. The balancing of supply and demand is expected to remain a tight exercise every year. At the end of the day, the future of the entire industry largely lies in technology because the final stake is to ensure the proper feeding of a 9 billion people population in a not too far future.","PeriodicalId":19493,"journal":{"name":"Oléagineux, Corps gras, Lipides","volume":"15 1","pages":"249-260"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81788072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Just as Europe did more than a century ago, China woke up and is about to regain the place in the economy it used to occupy at the beginning of the 19th century. In 2009, China was one of the fourth biggest buyers of agricultural lands in the world with Saudi Arabia, the United Arab Emirates and South Korea. Just as Europe did in 1945, over the last three decades China has built coastal infrastructures such as harbours, highways, airports, encouraging the mobility of people, goods and information. Cities and buildings have developed; there has been industrialization, supply of goods and services to consumers... and finally development of a middle class, especially on the East coast. Or more precisely two middle classes – an upper middle class (105 millions of consumers, with an income of 4 800$ to 12 500$/year) and a lower middle class (190 millions of consumers, with an income of 3 000$ to 4 800$/year) –, both responsible for the actual evolution of food consumption in China. Traditional consumption of rice is decreasing, just as potatoes did after the 60’s in France; meat and milk consumption (pork, chicken) are soaring. Consequently, the explosion of demand and changes in diets are increasing the strains on world agricultural commodity markets. Nobody knows if China is living the last days of these Golden Years (its gross domestic product (GDP) drop from 14 % to 8 % between 2007 and 2012) or if it is just a step before a new take-off based this time on Central China, after the one based on the East coast. And what about the consequences of the ageing of the Chinese population and of the ‘‘one child’’ policy on future changing lifestyles?","PeriodicalId":19493,"journal":{"name":"Oléagineux, Corps gras, Lipides","volume":"41 1","pages":"299-303"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80815143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thanks to the positive image that it acquired due to its health benefits, olive oil is more and more appreciated in countries where its consumption is recent and non traditional. On the contrary, in Mediterranean countries, namely in Tunisia, other vegetable oils and fats tend to substitute olive oil, which is more expensive.

Food transition then occurred for part of Chinese citizens, meaning more meat consumption and less grain consumption. Many factors explained this transition. As China’s economy grew rapidly, peoples’ average income have been rising and cities have been growing at a rapid pace. Foreign investments in retail also have played a major role. But some gaps remain throughout the country: income inequality between rural and urban, between people living on the coast and in-land people, among generations. . . Food transition is not over yet for an important part of the Chinese population.China was able to feed its population until the beginning of the 21st century. But the imports of soybean and milk products have widened its food trade deficit since 2004. The crisis that has been affecting the global economy for the past 4 years might force the Chinese authorities to boost home consumption to be able to maintain the economic growth. This move would mean more imports and might have big consequences on food international trade in the years to come.","PeriodicalId":19493,"journal":{"name":"Oléagineux, Corps gras, Lipides","volume":"54 1","pages":"290-299"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75292532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several elements of explanation have been put forward to explain this crisis, including traditional ones such as imbalance supply/demand and stocks, energy effect, dollar effect ; and new factors such as biofuels, financial speculation and low interest rates, export bans. Various arguments linked to this food crisis have also questioned the global nature of food security issue : global insecurity (with the urban food riots), humanitarian (with the worsening situation of the bottom billion), cross-sectoral (with the relationships between agriculture and other related issues such as environment, health, trade rules and market impacts, etc.). Several initiatives have insisted on the need to address more seriously the problem at the global level. Indeed, lack of global coordination on food security has been recognized as a major problem. This lack of coordination could be understood both at the substantive level (i.e. between the different issue-areas which are part of the food security problem) and at the institutional level (i.e. between the different international organizations in charge of food security) leading to the fragmentation of global food security governance. This paper respectively analyses these two dimensions of fragmentation in order to assess the extent to which current global initiatives better address coordination needs for global food security.","PeriodicalId":19493,"journal":{"name":"Oléagineux, Corps gras, Lipides","volume":"43 1","pages":"276-282"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86634476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They display a combination of phenotypic traits of the wild and domesticated forms of the species and infest between 15 and 20% of fields of sunflower crop in this area, although at variable levels. When the infestation is strong, it affects seed yield and oil quality. Molecular studies showed that weedy sunflowers most probably resulted from accidental crop-wild hybridization during the seed production process and from the introduction of the resulting hybrids into commercial seed lots. Multiple independent introductions were at the source of the number of infested fields observed nowadays. The temporal dynamics of the infestation of a field and the detailed conditions for its success remain largely unknown. The flowering synchrony between crops and weeds is substantial, even if a variable fraction of the weeds (15-55%) flower completely outside the crop flowering period. Molecular survey of adult weedy plants and their progenies showed that crop-toweed gene flow occurs, at a rate that can reach 35 %on average, at the peak of the crop flowering period. We draw perspectives on the durability of herbicide-tolerant sunflower varieties as a solution to control these weeds, and call for more studies tackling weed management from an evolutionary lens.","PeriodicalId":19493,"journal":{"name":"Oléagineux, Corps gras, Lipides","volume":"40 1","pages":"304-312"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85399058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
