The nuclear war between the two countries will be enough to cause world hunger

If two countries confronted with nuclear weapons, the local consequences were likely to be dramatic: the explosions would directly destroy the population and cause dangerous and persistent radioactive precipitation; however, an international group of researchers had considered the consequences of such a conflict on a broader scale: they had modelled several scenarios of nuclear war to track their impact on climate and food production.

They showed that the amount of soot produced by nuclear weapons into the stratosphere is blocking part of solar radiation, causing temperatures to decrease for at least a decade, which in turn will significantly reduce crop yields."" Lily Xia, a climatologist at Rutger University in New Brunswick, New Jersey, who led the study, said that more than 5 billion people could starve as a result of a nuclear war between the United States and Russia.

The effect would be comparable to the effect of the great volcanic eruptions that our planet experienced in the past: the eruption of Lucky in 1783 in Iceland and the eruption of Tambora in 1815 in Indonesia caused a global decrease in temperature due to the release of sulphuric acid into the stratosphere, leading to serious famine; the team notes that most recently, major fires in Canada in 2017 and Australia in 2019 and 2020 also produced large quantities of soot, which were transported around the world for several months, confirming that the same phenomenon would occur in the event of a nuclear war.

However, the consequences will depend on several factors, such as the number of weapons used, the nature of the targets and the atmosphere, and in this study scientists have considered six different war scenarios, each of which lasted one week and produced a different amount of stratospheric soot. They estimate that a war between India and Pakistan with powerful nuclear arsenals could lead to the release of between 5 and 47 Tog Sogi into the stratosphere. A war between the United States, its allies and Russia, which accounts for more than 90 per cent of the world ' s nuclear arsenal, could lead to the formation of more than 150 Tg sogi.

In each case, they took into account the total amount of food calories available in each country after the war, after the food supplies had been spent.

It is clear that the local impact will be the most significant: the infrastructure will be destroyed and the soil and water in the area will be immediately contaminated with radioactive materials.

Even in the worst-case scenario, the war between India and Pakistan with about 100 nuclear weapons, with a total of 5 Tg sogi emissions, the world's calorie production could fall by 7 per cent in the first five years after the conflict; over 250 million people could die of hunger in the first two years, researchers say. The study suggests that international food trade will be suspended, with each country choosing to meet the needs of its own population rather than export its resources.

The data show regional differences: the countries most affected will be those located in the high latitudes of the northern hemisphere, where already the relatively short season for cultivation of land crops and where cooling will make agriculture virtually impossible; similarly, countries that are currently heavily dependent on imports will be seriously affected. "", researchers note. Only Australia, which will be largely dependent on wheat, seems to be in a better position under any scenario.

Data also show that reducing household food waste may help in the event of a "small" nuclear war, but will not be sufficient in the worst scenarios to compensate for the significant decline in global production caused by climate.
