This book investigates food security and the implications of hyper-urbanisation and rapid growth of urban populations in Africa. By means of a series of case studies involving African cities of various sizes, it argues that, while the concept of food security holds value, it needs to be reconfigured to fit the everyday realities and distinctive trajectory of urbanisation in the region. The book goes on to discuss the urban context, where food insecurity is more a problem of access and changing consumption patterns than of insufficient food production. In closing, it approaches food insecurity in Africa as an increasingly urban problem that requires different responses from those applied to rural populations.

In this article, agrofuels are examined in the context of the world food price crisis and the "food sovereignty" proposal for addressing the crisis. Both short- and long-term causes of the crisis are examined, and while agrofuels are presently not a prime causal factor they are clearly contraindicated by the crisis. Food sovereignty, including a moratorium on agrofuels, is argued to offer the best option for managing the crisis.

International audience ; Food safety has become an important food quality attribute.Both food industry and authorities need to be able to trace back and to authenticate food products and raw materials used for food production to comply with legislation and to meet the food safety and food quality requirements. Traceability is increasingly becoming a necessary task in the food industry which is mainly driven by recent food crises and the consequent demands for transparency in the food chain. This is leading to the development of traceability concepts and technologies adapted to different food industry needs. The content of this paper include several aspects such as overseas food traceability system present conditions and development, food traceability system present conditions, problems and prospect in China, put forward the main measures of pushing on food traceability system of china.

Food insecurity can result from various events. While an adequate food supply is necessary, when food is abundant the entitlement to food is limited by endowments, the ability to trade, and potential transfers. This volume considers trends in economic growth, agricultural productivity growth, income and other policies that shape food security

Despite many factors weighing in South Africa's favor on the agricultural front, including having official "food secure" status, millions of households have insufficient access to nutritionally safe food. This is largely a function of poverty, which is particularly pervasive in the rural areas. While the government's largely unsuccessful agricultural development programs have focused on large-scale commercial crops, such as wheat and maize, indigenous and traditional food crops could play a significant role. In this article, multiple criteria analysis is used to identify indigenous and traditional food crops that have the greatest potential to enhance food security in South Africa. The different indigenous and traditional food crops options were rank according to set criteria that were derived from the definition for food security as adopted in the article. Accessibility, affordability and nutrition formed the basis of the definition as subsequently the criteria used to rank the alternatives. Results from the analysis revealed that sorghum, sweet potatoes, and amaranth are among the indigenous and traditional food crops with the greatest potentia
