A global assessment of the potential impact of climate change on world food supply suggests that doubling of the atmospheric carbon dioxide concentration will lead to only a small decrease in global crop production. But developing countries are likely to bear the brunt of the problem, and simulations of the effect of adaptive measures by farmers imply that these will do little to reduce the disparity between developed and developing countries.(From "Potential impact of climate change on world food supply"

GENEVA, Sep 3 (IPS) - A group of 125 non-governmental organisations from 50 countries is calling on the governments participating in the mini-ministerial trade talks in India over the next two days to reject the further liberalisation of food and rather promote policies that will achieve food security and rural development and safeguard farmers’ livelihoods.The organisations, of which 13 are in Africa, argue in a letter to the 36 countries attending the mini-ministerial meeting that the World Trade Organisation’s (WTO) policies have resulted in "a failed global agricultural system including extremely volatile commodities markets, a lack of global access to nutritious and affordable food, an increase in hunger, and the erosion of farmers’ incomes. "These policies have culminated in the global food crisis we face today, where about 30,000 people die every day of poverty related causes, many due to malnutrition and hunger. The FAO (Food and Agriculture Organisation) estimates that over one billion people are now going hungry, with about 150 million more people experiencing hunger as a result of the current food crisis," expound the organisations.

A main strategy on local policies on energy saving, agriculture and fisheries to lowering importation and not to pay unuseful or obsoleted technologist, in 2010, will decide the future of currency and credit in the international market of the developing countries of the Caribbean area facing to the increasingly economic crisis in United States and the dollar inflation in the midled of a climate change unpredictable. Analysts foresee an increase from 2.5 to 5.5% in global food prices but poor countries will pay much more...
To do otherwise is to fall into extreme poverty(1), incur more debt with a Foreign Powers and sell the national patrimony as happened to Menem's Argentina.
Gualterio Nunez Estrada, Sarasota, Florida, 34,233. (1)"When crop yield results are introduced to the BLS world food trade system model, the combined model and scenario experiments demonstrate that the world, for the most part, appears to be able to continue to feed itself under the SRES scenarios during the rest of this century. However, this outcome is achieved through production in the developed countries (which mostly benefit from climate change) compensating for declines projected, for the most part, for developing nations. While global production appears stable, regional differences in crop production are likely to grow stronger through time, leading to a significant polarisation of effects, with substantial increases in prices and risk of hunger amongst the poorer nations, especially under scenarios of greater inequality (A1FI and A2)."Effects of climate change on global food production under SRES emissions and socio-economic scenarios (From:References and further reading may be available for this article.

The UN World Food Program reported that unit food costs had risen by 50% in five years, with maize costs up 120% over the year to June 2007. The UN FAO estimated that the cost of imported food in 2008 was US$ 1.04 trillion, 26% up on 2007. A FAO / OECD report predicts food price increases of between 20% and 50% over the next ten years, due to reduced subsidies, greater demand for protein, higher production costs and the demand for biofuels. According to the UN FAO the price of dairy products rose 80% and grain 42% during 2007.
