# Deforestation Risks Brazil's Agricultural Export Stability New research links Amazon and Cerrado deforestation to critical rainfall reductions affecting soy and beef. - **Source:** [Agência Brasil](https://agenciabrasil.ebc.com.br) - **Published:** 2026-11-11 - **Topic:** [climate](https://brifing.si/c/climate) - **Original article:** - **On Brifing:** https://brifing.si/s/869543c8-7507-416d-8da8-8a191395efb3 ## Climate Impact on Agriculture A study by WRI Brasil reveals that deforestation directly triggers rainfall declines, threatening Brazil's soy and beef production. Presented at the COP31 conference in Turkey, the research highlights how environmental degradation undermines the stability of key agricultural sectors. These findings emphasize the urgent link between ecological preservation and national economic performance. ## Three Decades of Data Researchers analyzed climate trends between 1993 and 2023, focusing on regions critical to exports. The data shows the rainy season shortened by up to 75 days in parts of the Amazon and 45 days in the Cerrado. Simultaneously, days with temperatures exceeding 35°C increased significantly, further stressing local ecosystems and crop development. ## Economic Export Vulnerability China remains the primary buyer of Brazilian soy and beef, importing approximately 70% of soy and over half of the beef. Because these commodities are vital for Brazil's trade surplus, the environmental risks identified in the study pose a direct threat to the country's long-term commercial competitiveness and international trade relations. ## Mechanism of Production Loss The study establishes a clear statistical association between native vegetation loss and reduced rainfall volumes. With less rain, the development window for crops shrinks, and pasture growth for cattle is severely hindered. This environmental shift directly reduces the productivity of the agribusiness sector, which relies on consistent seasonal weather patterns. ## Strategic Risk Management Mariana Oliveira, director at WRI Brasil, stresses that maintaining agricultural competitiveness requires proactive climate risk management. The study argues that the sector's success is inseparable from environmental health. Stakeholders must now prioritize the anticipation of climate-related disruptions to protect the future of Brazil's most significant export-driven industries and global supply chains. ## Proposed Policy Interventions The research recommends accelerating the validation of the Rural Environmental Registry (CAR) to improve land monitoring. Strengthening fiscal oversight and expanding incentives for native vegetation restoration are also proposed as essential steps. These measures aim to optimize production while simultaneously recovering degraded areas to stabilize the regional climate and agricultural output. ## Role of International Cooperation Virginia Antonioli suggests that China, as the primary importer, could play a crucial role in supporting these sustainability efforts. By sharing data to identify environmental risks within supply chains, China can help ensure the long-term viability of its imports. Brazil already possesses the necessary instruments to combat deforestation and restore degraded lands. ## Global Policy Implications The presentation of these findings at COP31 underscores the global importance of Brazil's land-use policies. By linking local deforestation to international food security and trade, the study provides a framework for future climate negotiations. The focus remains on implementing existing tools to mitigate risks for both producers and global consumers. ## Sources covering this story - https://agenciabrasil.ebc.com.br/meio-ambiente/noticia/2026-11/cop-31-estudo-mostra-que-agro-pode-ter-prejuizo-com-desmatamento — --- _Summary written by Brifing from the original reporting.
