Abstract The adverse climate change effects motivate searches for renewable energy sources. Among them, ethanol from sugarcane stands out. Currently, the state of Sao Paulo is responsible for more than half of Brazilian ethanol production. Considering the increasing demand for ethanol in the future, the influence of climate change effects on cultivation should be assessed. To identify areas suitable for expansion, the Brazilian government carried out the Sugarcane Agroecological Zoning (AEZ-Sugarcane); however, it did not consider future scenarios of climate change. In this context, this work aimed to model the sugarcane expansion in Sao Paulo in the years 2041 and 2060 to map low-risk areas based on climate change scenarios, in addition to comparing the expansion areas from the model with suitable AEZ-Sugarcane areas. Additionally, this work aimed to analyze recommended expansion areas by AEZ-Sugarcane according to future climate suitability. Sugarcane cultivation registers a massive expansion trend of 123% and 145% in the years 2041 and 2060, respectively, more prominent for the West, Northwest and North regions. In the years 2041 and 2060, the amount of expansion areas mapped in this study coinciding with those recommended by the AEZ-Sugarcane are 74% and 71% of the total modeled. Although in 2041-2060 all states are classified as low climate risk according to the AEZ-Sugarcane adopted methodology, it is estimated that 45% and 3% areas classified as suitable by AEZ-Sugarcane will require rescue irrigation, considering each of the two future scenarios studied.

巴西圣保罗州计划扩大甘蔗种植面积的适应性:一项基于气候变化影响的研究

摘要 不利的气候变化影响促使人们寻找可再生能源。其中,甘蔗乙醇最为突出。目前,圣保罗州占巴西乙醇产量的一半以上。考虑到未来对乙醇的需求不断增加,应评估气候变化对种植的影响。为确定适合扩展的区域,巴西政府实施了甘蔗农业生态区划(AEZ-Sugarcane);然而,它没有考虑气候变化的未来情景。在此背景下,这项工作旨在模拟 2041 年和 2060 年圣保罗的甘蔗扩张,以根据气候变化情景绘制低风险区域,此外还将模型中的扩张区域与合适的 AEZ-甘蔗区域进行比较。此外,这项工作旨在根据未来的气候适宜性分析 AEZ-Sugarcane 推荐的扩展区域。甘蔗种植在 2041 年和 2060 年分别出现 123% 和 145% 的大规模扩张趋势,西部、西北和北部地区更为突出。在 2041 年和 2060 年,本研究绘制的扩展区域数量与 AEZ-Sugarcane 推荐的数量一致,分别为建模总数的 74% 和 71%。尽管根据 AEZ-Sugarcane 采用的方法,所有州在 2041-2060 年都被归类为低气候风险,但考虑到两个未来情景研究。甘蔗种植在 2041 年和 2060 年分别出现 123% 和 145% 的大规模扩张趋势,西部、西北和北部地区更为突出。在 2041 年和 2060 年,本研究绘制的扩展区域数量与 AEZ-Sugarcane 推荐的数量一致,分别为建模总数的 74% 和 71%。尽管根据 AEZ-Sugarcane 采用的方法,所有州在 2041-2060 年都被归类为低气候风险,但考虑到两个未来情景研究。甘蔗种植在 2041 年和 2060 年分别出现 123% 和 145% 的大规模扩张趋势,西部、西北和北部地区更为突出。在 2041 年和 2060 年,本研究绘制的扩展区域数量与 AEZ-Sugarcane 推荐的数量一致,分别为建模总数的 74% 和 71%。尽管根据 AEZ-Sugarcane 采用的方法,所有州在 2041-2060 年都被归类为低气候风险,但考虑到两个未来情景研究。本研究中绘制的扩展区域数量与 AEZ-Sugarcane 推荐的数量一致,分别为建模总数的 74% 和 71%。尽管根据 AEZ-Sugarcane 采用的方法,所有州在 2041-2060 年都被归类为低气候风险,但考虑到两个未来情景研究。本研究中绘制的扩展区域数量与 AEZ-Sugarcane 推荐的数量一致,分别为建模总数的 74% 和 71%。尽管根据 AEZ-Sugarcane 采用的方法,所有州在 2041-2060 年都被归类为低气候风险,但考虑到两个未来情景研究。
