Water, investment and food security
2011
Chartres, Colin J.
Water resources are already very scarce. With further demand from population growth, dietary changes, biofuel production, urbanisation and climate change, it will be extremely difficult to find enough supply to enable an increase in global food production by 70 per cent. There are, however, potential solutions that involve increasing water productivity, improved water storage, more irrigation and re-using waste water. But current investment levels in overseas development aid and spending at country level are unlikely to be sufficient to ensure food security in the relatively short- term, let alone by 2050, when the global population is forecast to be nine billion. This article describes some of the issues that have to be faced to deliver food security and overcome water scarcity, and how these improvements can be achieved through a combination of science, policy and investment.

The measurement of A(, w) can supply useful information as to the chemical and biological stability of food products. In this review the following subjects are treated: (a) mathematical equation suggested in literature to describe water sorption isotherms of food systems. (b) A(, w) of systems with high and low water content. (c) A(, w) prevision in I.M.F. (d) Effect of A(, w) on degradative reactions. | La misura dell'attivita dell'acqua (A(, w)) e in grado di fornire utili indicazioni sulla stabilita chimica e biologica dei prodotti alimentari. Dopo aver definito i concetti di A(, w) e di isoterma di adsorbimento vengono sinteticamente trattati i seguenti aspetti: (a) Espressioni matematiche proposte in letteratura per descrivere le isoterme di adsorbimento dei sistemi alimentari. (b) A(, w) dei sistemi ad alto e basso contenuto in acqua. (c) Previsione dell'A(, w) dei sistemi ad umidita intermedia. (d) Influenza dell'A(, w) sulle principali reazioni degradative.

En esta Monografia se trata el tema de la utilizacion del cloro y sus compuestos como medio de alcanzar los requisitos sanitarios que deben cumplir las aguas utilizadas en la industria alimentaria. Se explica la terminologia empleada en cloracion asi como la quimica del cloro en el agua y su comportamiento en funcion de Ph y temperatura. Se ejemplifican distintos sistemas de cloracion y finalmente se hace referencia a un posible programa de control de la cloracion en planta y a metodos analiticos para la evaluacion del cloro activo.
