It is well known that temporal changes in bivalve body mass are strongly correlated with temporal variations in water temperature and food supply. In order to study the influence of the year-to-year variability of environmental factors on oyster growth, we coupled a biogeochemical sub-model, which simulates trophic resources of oysters (i.e. phytoplankton biomass via chlorophyll a), and an ecophysiological sub-model, which simulates growth and reproduction (i.e. gametogenesis and spawning), using mechanistic bases. The biogeochemical sub-model successfully simulated phytoplankton dynamics using river nutrient inputs and meteorological factors as forcing functions. Adequate simulation of oyster growth dynamics requires a relevant food quantifier compatible...

Child Development: Vulnerability and Resilience
Provedor de dados: 31
Autores: Engle,   Patrice L.; Castle,   Sarah; Menon,   Purnima.
Many of the challenges facing children now are a function of the changing times, including increases in urbanization, political violence, changing family forms, and, in some areas, decreased supplies of adequate food. This paper reviews the evolving nature of these risks. In addition, the paper analyzes the development of formal and informal strategies to ameliorate the vulnerability and promote the resilience of young children to these risks. The paper identifies four stages in the research process regarding risks for children: (1) identification of the risk; (2) clarification of etiology and consequences; (3) recognition of resilience among some individuals; and (4) definition of factors in resilience and implications for intervention.

Globalisation of Indian Diets and the Transformation of Food Supply Systems
Provedor de dados: 31
Autores: Pingali,   Prabhu L.; Khwaja,   Yasmeen.
This paper examines the change in the nature of food demand in India in the last twenty years. It identifies two distinct stages of diet transition associated with the period of economic growth. During the first stage, income-induced diet diversification, consumers move away from inferior goods to superior foods and substitute some traditional staples, especially rice. In the second stage, diet globalisation, the influences of globalisation are much more marked with increased consumption of proteins, sugars and fats. Diet diversification has marked the process of transformation in food production systems. The implications for small and marginal farmers could be serious, unless there are incentives and policies that allow them to move away from subsistence...

NEW CHALLENGES FOR RISK MANAGEMENT IN AGRI-FOOD INDUSTRY
Provedor de dados: 31
Autores: Gerasymenko,   Nataliia; Zhemoyda,   Oleksandr V.
Increasing of population in some part of the world demands appropriate quantity and quality of food supply. It leads agri-food production to changes having many of the characteristics of manufacturing industries. So, together with the advantages we have to manage also different deficiencies. The changing business climate is creating new agriculture with new risks. And some of these risks require new approaches and different perspectives to evaluate and manage them adequately. The new risks create both challenges and opportunities for agri-food producers and those who finance them. Furthermore, the common perception is that vertical linkages through contract production will also reduce risks quality and quantity. The industrialization of agriculture is...
