But an October study shows deforestation is hurting farmers too. The report shows that the practice of clear-cutting (removing all trees from a given area) in the Brazilian Amazon reduced crop yields, resulting in economic losses of about $1bn between 2006 and 2019, and threatening global food security. When ancient forests become plains, a delicate balance of water cycles is destroyed. As trees respire, they convert water into vapour, forming large, dense rain clouds that cool the region. This moisture-recycling process also influences atmospheric circulation, which plays a key role in temperature regulation (调节) in the Amazon basin. The effects are clearest where more than 80% of the forest has been cleared. The rainy season has been delayed by 76 days since 1980. Between 1999 and 2019, rainfall fell by 40% in the soybean season and 23% at maize time. Maximum air temperatures rose by 2.5 ℃ over the same period. Less rain and hotter days mean smaller harvests and lower incomes. Preventing further deforestation in Brazil’s southern Amazon could slow this. If clear-cutting continues, farmers may lose up to $1bn a year. Reforesting could even reverse (逆转) rainfall trends: if state of Pará were to reforest 55,000 km2, the rain could come on average five days earlier and up to 19 in some areas, adding 152mm annual rainfall. For now, though, that seems like a tall order. Agricultural firms tend to treat such reports with scepticism. Despite the rising costs of adapting to drier conditions, farmers question the link between lower yields and climate change or deforestation. Britaldo Soares-Filho, a researcher at UFMG and the report’s lead author, hopes that focusing on the financial impact of deforestation can bring critics round. Sustainable farming practices, he argues, are in the economic interests of agribusiness. 1.What can be inferred about the role of water cycles in paragraph 3 A. Increase regional temperatures. B.
