Spatial determinants of abandonment of large-scale arable lands and managed grasslands in Slovakia during the periods of post-socialist transition and European Union accession

Exploring the Factors Driving Seasonal Farmland Abandonment: A Case Study at the Regional Level in Hunan Province, Central China

“…Low-yield land is often abandoned first. This finding also confirms the previous findings at the parcel level [9,48].…”

“…It has brought about many positive effects, such as forest re-growth [3], recovery of ecosystem services [4], and enhancement of carbon sink capacity and biodiversity [3,[5][6][7]. However, many negative effects have also been found, including the disappearance of traditional farming practices; loss of habitats with high ecological, cultural, and aesthetic value; increased risk of wildfires; and species invasion [8][9][10][11][12][13]. What is worthy of more attention is the consequent challenges for food security, especially in areas where arable land is highly scarce, such as China and Japan [12,14].…”

Mapping Secondary Forest Succession on Abandoned Agricultural Land with LiDAR Point Clouds and Terrestrial Photography

“…The accuracy assessment showed vertical and horizontal root mean square errors (RMSEs) of 0.10 m and 0.23 m, respectively [75]. Within the ISOK project, the data were already classified according to the American Society for Photogrammetry and Remote Sensing standards [76] into ground (class 2), low (3), medium (4) and high (5) vegetation, buildings (6), low points (7), model key-points (8), water (9) and others. Data classification in ISOK was performed automatically, but the classification process was followed by a visual inspection and manual correction of misclassified points.…”

“…For more than 100 years, Europe has experienced an increase in forest cover [2][3][4] due to afforestation and forest expansion on abandoned agricultural land. The latter has played a significant role in land cover changes in Europe over the past several decades [5][6][7][8], particularly in marginal mountain areas [9][10][11][12][13][14]. The Polish Carpathians have experienced a gradual decline of agricultural areas since World War II that accelerated after the collapse of the Soviet Union and related socio-economic transformations [15][16][17][18] as well as a significant increase in fallow or abandoned agricultural land with visible signs of forest succession.…”

中国2000-2010年耕地低效转化的空间特征

“…。 其次，在农牧交错带等特定地区，受降水波动的影响，种植业与牧业交替进行，耕地向 草地转化时常发生。最后，至关重要的影响来自城市化的快速发展。随着大量农村剩余 劳动力向城市转移，加上农地流转不畅，人为导致的耕地撂荒现象日益严重 [3][4] 。从土地 利用变化的结果来看，在一定时间内，上述 3 种情况均表现为耕地向草地、灌木或裸地 的转化 [2,5] 。这种利用方式由集约型向粗放型、产出效益趋于减少的转化可以认为是耕地 的低效转化。耕地低效转化不仅影响粮食产量，还对生物多样性、土壤恢复、碳汇等具 有重要影响 [6][7] 。因此，利用高精度遥感数据分析耕地低效转化的空间分布特征，既可以 揭示我国土地利用变化的现状和问题，又有助于进一步探究其相关效应，为制定保证区 [8] 。相对而言，对于耕地撂荒 （Cropland Abandonment） 、农牧转化等造 成耕地低效转化的研究关注较少，且"撂荒"的含义也不确定 [7,[9][10][11] 。比如 Lieskovský等将 欧洲 CORINE Land Cover 分类系统中原有耕地转化为灌木或草本植物、少植被或无植被 覆盖的空地、内陆湿地的部分作为撂荒耕地 [12][13][14] Table 3 The regional decomposition of Theil Index and its percentage contribute …”
