ABSTRACT Worldwide, loss of farmland due to transition to other land uses is recognized as a major challenge. Data from the Land Parcel Identification System (LPIS) are potentially useful to assess agricultural land use dynamics as they contain detailed information on agricultural land use. In this paper, we therefore analyse data from two individual studies, one from Flanders and one from Denmark, to explore whether LPIS data are applicable to assess farmland loss. Our results show that in both Flanders and Denmark, around 4.5% of the total registered farmland area in LPIS was lost in a 5-year period (2008–2013 for Flanders and 2011–2016 for Denmark). Complementary land use data and aerial photo interpretation reveal that the majority of lost registered farmland still was in agricultural use after 5 years. Hence, the confirmed loss was only around 0.5% for Flanders and Denmark. We conclude that both Flemish and Danish LPIS data only with some difficulty are able to quantify loss of farmland and therefore question if LPIS data alone are suitable to assess change in farmland area. The major part of farmland leaving the register is most likely related to a general change in agricultural structure.

应用 LPIS 数据评估农业用地损失——来自法兰德斯和丹麦的经验

摘要 在世界范围内，由于向其他土地用途过渡而导致的农田损失被认为是一项重大挑战。来自地块识别系统 (LPIS) 的数据对于评估农业用地动态可能有用，因为它们包含有关农业用地使用的详细信息。因此，在本文中，我们分析了两项单独研究的数据，一项来自法兰德斯，一项来自丹麦，以探讨 LPIS 数据是否适用于评估农田损失。我们的结果表明，在佛兰德斯和丹麦，LPIS 登记的农田总面积的 4.5% 在 5 年期间丢失（佛兰德斯为 2008-2013 年，丹麦为 2011-2016 年）。补充的土地利用数据和航拍图解显示，5 年后大部分丧失的登记农田仍为农业用途。因此，法兰德斯和丹麦的确认损失仅为 0.5% 左右。我们得出结论，佛兰芒语和丹麦语 LPIS 数据仅在一定程度上能够量化农田损失，因此质疑仅 LPIS 数据是否适合评估农田面积的变化。大部分退出登记的农田很可能与农业结构的总体变化有关。
