Climate crisis in Latin America threatens world food

HeatThe dry And this Floodsincreasing due to climate change, Crops destroyed in Latin America in 2021, According to the latest report of World Meteorological Organization (WMO).

Warming is intensifying in Latin America and the CaribbeanAccording to the second report on “Climatic Conditions in Latin America and the Caribbean”, temperatures in the region have increased by an average of 0.2 °C per decade between 1991 and 2021, compared with an average of 0.1 °C per decade between 1961 and 1990. developed. of WMO, published Friday.

“The report shows that, unfortunately, hydro-meteorological hazards – such as droughts, heat waves, cold waves, tropical cyclones and floods – have caused hundreds of lives lost, severe damage to agricultural production and infrastructure. and has caused population displacement, the WMO Secretary General said, peteri talas, This is a statement.

Slight fall in global food prices may bring relief to buyers

“In South America, the continued degradation of the Amazon rainforest remains a main cause of concern. Looking at the role of forest type in the carbon cycle, for both region and global climate. ,

The planet has already reached temperatures of 1.1 °C above the pre-industrial average and greenhouse gas concentrations in the atmosphere continue to rise. Developing countries, like many countries in South America, are most affected by the consequences of global warming, mainly due to carbon emissions released by developed countries.

Below average rainfall in major agricultural producers such as Chile, Brazil, Uruguay and Paraguay According to research by the Food and Agriculture Organization (FAO) of the United Nations cited in the report, the South American cereal crop has decreased by 2.6% in the 2020-2021 season compared to the previous season. Changes in rainfall patterns were partly related to La Nia, while climate change has played a major role in at least some extreme weather events in the region.

a Drought in Chile continues into 2021 According to the WMO, for the 13th year in a row, it remains the region’s longest drought in at least 1,000 years. The latest report from the Intergovernmental Panel on Climate Change (IPCC) says there is moderate certainty that droughts in central Chile can be attributed to human influence.

Grain exports, 80% of which pass through the Paraná River, were affected even after water levels fell to their lowest level since 1940.

According to the IPCC’s “Sixth Assessment Report”, climate impacts in the region are expected to worsen as precipitation patterns are changing, temperatures are rising, the Andean glaciers are melting and the continent’s two large oceans – the Pacific and the Atlantic. – It’s getting hot. and the resulting acidification of carbon dioxide.

In addition, deforestation

las The rate of deforestation in the Brazilian Amazon rainforest has doubled from the 2009-2018 average and reached the highest level since 2009, according to the report. Tropical forests have also been affected by fires: in 2021, 75,000 fires were reported, most of which were linked to human activity.

In 2021, floods were also recorded in the Brazilian Amazon, affecting more than 450,000 people and causing approximately US$40 million in damage. In the states of Bahia and Minas Gerais, the flood caused approximately US$3.1 billion in damage and affected more than 800,000 people.

“The The intensity of climate change and the combined effects of the COVID-19 pandemic not only have affected the biodiversity of the region, They have also halted decades of progress against poverty, food insecurity and the reduction of inequalities in the region,” Mario Simoli, interim executive secretary of the Economic Commission for Latin America and the Caribbean (ECLAC), said in a statement.
