Brazil's climate assessment report says global warming won't reduce agricultural production in Brazil

World Agrochemical Network: No matter how the global temperature changes, Brazil's agricultural production will continue to rise. The forecast was made by Nelson Ananias Filho, technical adviser of the Brazilian Federation of Agriculture and Livestock (CNA), at a hearing held by the Agriculture, Livestock, Rural Development and Supply Committee of the Chamber of Deputies.

At the hearing, scientists explained the contents of the first national assessment of climate change. This report summarizes the results of more than 300 Brazilian researchers. The report shows that by 2100, the average temperature will rise by 3-6 degrees Celsius. This will affect rainfall in Brazil: in the southeast and the Mata Atlantica region in the south, rainfall may increase by 30%, while in parts of the Amazon and Katinga drought will occur, with rainfall reduced by up to 40%.

Disagreement

at the hearing, Luiz Carlos Molion, a professor at the Centre for Meteorology at the Federal University of Aragoas, criticized the report by the Brazilian Climate Change Research Group and refuted the findings of most scientists. Molion believes global temperatures will drop over the next 20 years.

He believes that the sun's activity is periodic, the star will enter a period of low activity and emit less heat. In addition, the temperature of several oceans, especially the Pacific Ocean, is also falling, which will also have an impact on the global temperature drop.

Adaptation

the disagreement did not influence CNA consultant Nelson Ananias Filhoa's opinion on climate change. He said: "We will seize every opportunity to increase agricultural production.

Eduardo Assad, a researcher at the Brazilian Agri-Tech Company (Embrapa), was involved in drafting the national assessment report on climate change. He reaffirmed predictions that temperatures could rise across the country.

Assad added another consequence of climate change in Brazil, namely the increased frequency of "extreme events. He said: "What used to be considered normal still occurs and is increasing, with several days of the year when the temperature is surprisingly high, some days when it rains particularly heavily, and some days when the temperature is particularly low. These climatic phenomena can have a strong impact, especially on Brazil's agriculture and the population in the poorest areas".

Embrapa researchers believe that this will adversely affect soybean, corn, coffee and wheat yields in the first place. But on the other hand, rising temperatures are beneficial to grassland growth and sugarcane production.

Eduardo Assad stressed that one way to reduce the impact of climate change on agriculture is to grow adaptive plants. For example, he said, some corn grown in northern Brazil can withstand high temperatures and uncertain rainfall. These corn can be tested in the south. According to his information, these corn grown in the northeast are not as productive as the varieties in the south, but they also provide farmers in that area with an alternative to planting.
