Wani, S P | Boomiraj, K
Climate Change is real and its implications are going to be borne by the poorest of the poor. If climatic change is accompanied by an increase in climate variability, many agricultural Producers will experience define hardships and increased risk. The Sat regions, which have economies largely based on weather-sensitive agricultural productions systems, are particularly vulnerable to climate change...............................

The role of water in food quality decay Texte intégral
2010
Laura Piazza
The impact of water on food thermodynamics and physics, and therefore on its quality, is more important than any other food chemical component. When fundamentals of chemical kinetics apply, the rates of the reactions that are responsible of food quality decay can be described as a function of food composition and of other external elements interacting with foods. Among them, water activity and water content have been widely used to determine the role of water in the kinetic reactions of deterioration. Recently, researchers have found limitations in using the water activity parameter. According to them, the role of water in foods can be better described by evaluating the role in the stability of the quality attributes of the non-equilibrium states of amorphous food products. Following this approach, the dynamics of the changes are described in kinetics terms and can be efficiently better predicted by the glass transition temperature more than by the water activity. The glass transition, which is a second order transition in amorphous materials from the glassy to the rubbery state, is primarily dependent on water which is a plasticizer and is responsible for the physical state of multiphase systems (as foods are) together with the temperature. The subject of the role of water in the decay of food quality will be presented in this paper according to the principles of food material science.

In recent years, a greater level of integration of the world economy and an opening of national markets to trade has impacted virtually all areas of society. The process of globalization has the potential to generate long-term benefits for developing countries, including enhanced technology and knowledge transfers and new fina- ing options supporting agricultural and economic development. However, risks of political and economic instability, increased inequality, and losses in agricultural income and production for countries that subsidize their agricultural and other e- nomic sectors threaten to offset potential benefits. Globalization can also have a profound impact on the water sector – in terms of allocation and use of water – and thus on food security as well. Other global change processes, particularly climate change, are also likely to have far-reaching impacts on water and food security, and societies around the world. To discuss these issues in-depth, the International Food Policy Research Institute, the Third World Centre for Water Management, Mexico, and the Tropical Agricultural Research and Higher Education Center (CATIE), Costa Rica, held a three-day International Conference on “Globalization and Trade: Implications for Water and Food Security,” at CATIE’s Turrialba, Costa Rica, headquarters under the auspices of the CGIAR Challenge Program on Water and Food in 2005. The workshop set out to identify the major risks and emerging issues facing developing countries related to global economic and environmental change impacts on water and food security.
