We take note of your communication following the report by Dr. Paolo Bazzoffi regarding the copyright infringement of the paper ‘Effectiveness of the GAEC cross-compliance standard short-term measures for runoff water control on sloping land (temporary ditches and grass strips) in controlling soil erosion’ (Authors: Bazzoffi, Ciancaglini, Laruccia), that can be found at the following address: https://www.agronomy.it/index.php/agro/ article/view/ija.2011.6.s1.e3.
The title of the retracted publication is: ‘Temporary ditches are effective in reducing soil erosion in hilly areas. An evaluation with the RUSLE model’ (Authors: Francaviglia, Neri), that can be found at the following address: https://www.agronomy.it/index. php/agro/article/view/1762).
The undersigned authors thoroughly agree with the points raised by Dr. Paolo Bazzoffi in relation to the copyright infringement.
In particular, we agree that the original paper ‘Effectiveness of the GAEC cross compliance standard short-term measures for runoff water control on sloping land (temporary ditches and grass strips) in controlling soil erosion’ was not clearly indicated as original data source in the paper ‘Temporary ditches are effective in reducing soil erosion in hilly areas. An evaluation with the RUSLE model’.
We also recognize that we did not give credit to Dr. Paolo Bazzoffi of the original methodology, particularly: i) the original materials and methods; ii) the GIS elaboration; and iii) the original data and results.
The authors declare that:
- they considered the opportunity to review the data published by Dr. Bazzoffi et al. shown in Table 7 of their original publication after a data re-elaboration, as shown in Table 3 of the publication to be retracted, with the aim to provide a statistical comparison of erosion in hilly agricultural land among the Italian Regions, as well as introducing an evaluation of the weight of the parameters implemented in the RUSLE model using a multiple regression technique;
- they are aware of not having adequately recognized the copyrights of Dr. Bazzoffi and co-authors Ciancaglini and Laruccia.
For these reasons, and as requested, we retract the paper ‘Temporary ditches are effective in reducing soil erosion in hilly areas. An evaluation with the RUSLE model’ from publication. We apologize to Dr. Bazzoffi, Dr. Ciancaglini and Dr. Laruccia for the unpleasant inconvenience caused. We also take the opportunity to thank Dr. Paolo Bazzoffi for coordinating the EFFICOND and MONACO projects, in which we participated in various work packages, offering the possibility of a valuable and constructive work experience.

Sincerely,
Rosa Francaviglia and Ulderico Neri

我们注意到您在 Paolo Bazzoffi 博士关于论文 ' Effective of the GAEC cross-compliance-standards of runoff water control on the 坡地（临时沟渠和草带）的有效性的报告后的来信土壤侵蚀”（作者：Bazzoffi、Ciancaglini、Laruccia），可在以下地址找到：https://www.agronomy.it/index.php/agro/article/view/ija.2011.6.s1.e3。
收回的出版物的标题是：“临时沟渠可以有效减少丘陵地区的水土流失。” 使用 RUSLE 模型进行的评估（作者：Francaviglia，Neri），可在以下地址找到：https://www.agronomy.it/index。php/agro/article/view/1762）。
下面署名的作者完全同意 Paolo Bazzoffi 博士提出的有关侵犯版权的观点。
特别是，我们同意原论文《坡地（临时沟渠和草带）径流水控制控制水土流失的短期措施的有效性论文 '临时沟渠可有效减少丘陵地区的水土流失。使用 RUSLE 模型进行评估'。
我们也承认我们没有将原始方法学归功于 Paolo Bazzoffi 博士，特别是：i) 原始材料和方法；ii) GIS 细化；iii) 原始数据和结果。
作者声明：
- 他们考虑了审查 Bazzoffi 博士等人发表的数据的机会。数据重新阐述后显示在其原始出版物的表 7 中，如要收回的出版物表 3 所示，旨在提供意大利地区之间丘陵农地侵蚀的统计比较，并引入使用多元回归技术评估 RUSLE 模型中实现的参数的权重；
- 他们意识到没有充分承认 Bazzoffi 博士以及共同作者 Ciancaglini 和 Laruccia 的版权。
出于这些原因，并根据要求，我们撤回了论文“临时沟渠可有效减少丘陵地区的水土流失。使用 RUSLE 模型进行评估' 来自出版物。对于给您带来的不便，我们向 Bazzoffi 博士、Ciancaglini 博士和 Laruccia 博士道歉。我们也借此机会感谢 Paolo Bazzoffi 博士协调 EFFICOND 和 MONACO 项目，我们参与了各种工作包，提供了宝贵和建设性的工作经验的可能性。

此致，
Rosa Francaviglia 和 Ulderico Neri
