Colin J. Chartres, 'Water, investment and food security', 2014 | 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

Demin, A. P.
Data on the volumes of renewable water resources and the specific dependable water supply are given for countries with the least water resources available. Data on the current volumes of water resources withdrawal, irrigated land area, and the population size in largest world countries are given. Measures taken by various countries with the aim to enhance water resources availability for agriculture are described. The further increase in the area of arable and irrigated lands, with the current technologies still in use in the agriculture, is shown to be inadmissible. The role of reclamation in the ensuring of food safety in Russia is demonstrated.
