“…Regardless of the causes of cropland abandonment, the concerns related to land degradation remain (Sankey, Massey, Yadav, Congalton, & Tilton, 2018). Therefore, it is important to understand the spatiotemporal patterns of historical cropland abandonment and potential future trends for both food security and sustainable environmental management (Castro, Pedroso, Lautenbach, Villanueva, & Vicens, 2019; Hatna & Bakker, 2011).…”

Urban expansion or poor productivity: Explaining regional differences in cropland abandonment in China during the early 21st century

Cropland abandonment has long been recognized as a marginalization process in rural regions but recently also as a precursor to urbanization in peri-urban regions. This study aimed to evaluate the relative importance of urbanization and poor productivity in cropland abandonment. A thorough investigation was conducted on 345 cities/ towns at the prefecture level or higher in China using 500-m annual maps for 2003-2016. Cropland abandonment was spatiotemporally coupled with the urbanization. At a national scale, approximately 0.55% of the total cropland area (approximately 862 km 2 per year) has been abandoned. Cropland abandonment increased significantly until 2009, declined in the early 2010s, and then leveled off in recent years. In particular, the new first-tier cities suffered the greatest abandonment per capita. However, cropland abandonment was increasingly shifted to lower-tier cities, particularly the high-quality cropland abandonment in the medium-tier cities. Lowquality cropland in rural regions of the medium-and lower-tier cities experienced incessant abandonment. Results showed that the extent of cropland abandonment increased with city sizes described either by population/GDP or by built-up area. High-quality cropland abandonment was more closely related to the built-up area than to population and GDP for total abandonment. Urbanization-induced abandonment in peri-urban areas was dominant for most cities, with exceptions only for a few small cities. Contrary to expectation, cropland abandonment for most cities/ towns in rural regions was not more driven by poor productivity, compared to periurban regions. Our study highlights that urbanization mainly accounted for the regional differences in cropland abandonment in China during the past two decades.

“…Já outras famílias pareciam ser mais afetadas pelas dinâmicas contemporâneas de um novo rural, muito mais híbrido e com características "rurbanas" (CARNEIRO; CASTRO, 2007). Essas famílias "menos rurais" provavelmente podiam lidar, de modo mais consonante ou menos tenso, com as lógicas escolares, e com as formas e funcionamento da escola.…”

O artigo apresenta resultados de uma pesquisa que investigou as condições em que ocorrem as situações de distorção idade-série entre estudantes que residem em territórios rurais. Foram analisadas as percepções de gestores escolares sobre esse fenômeno, em especial o modo como eles explicam sua ocorrência nas escolas. A metodologia utilizada foi qualitativa e envolveu a realização de entrevistas com os gestores de cinco unidades escolares. Os resultados indicam que, na ótica desses profissionais, dois conjuntos de fatores estariam na base do fracasso escolar dos estudantes: fatores extraescolares e fatores escolares, sintetizados como descompassos entre a modalidade de oferta escolar (currículos, tempos e espaços) e a realidade social e cultural vivenciada pelos estudantes em contextos rurais.

“…The problem has aroused the attention of both the Chinese government and researchers in an attempt to understand its root causes and find solutions to slow down the pace of abandonment (Liu et al, 2016; Qin & Liao, 2016; Xu, Deng, Huang, et al, 2019). Farmland abandonment is common in both developed and developing countries and regions, including parts of Europe (Baumann et al, 2011; Dolton‐Thornton, 2021; Price et al, 2015; San Roman Sanz et al, 2013; Zavalloni et al, 2021), Southeast Asia (Fox et al, 2009), Brazil (Castro et al, 2019), and Ecuador (Caulfield et al, 2019). A number of organisations, including the Institute for European Environmental Policy (IEEP), the European Union (EU), and the United Nations Educational, Scientific and Cultural Organisation (UNESCO), have taken measures to avoid further farmland abandonment (Levers et al, 2018).…”

Examining pathways linking rural labour outflows to the abandonment of arable land in China

Against the backdrop of increasing rural labour outflow in China, the marginalisation of agriculture and arable land abandonment has become prevalent. Previous studies have examined the linkages between rural labour outflow and arable land at the national scale but have largely ignored regional differences. Moreover, mechanisms linking rural labour outflow to abandonment have not been analysed systematically. This study uses 2016 China Labour‐force Dynamics Survey data (CLDS) and structural equation models (SEMs) to examine the means by which rural labour outflows affect arable land abandonment regionally. The analysis focuses on the mediating role and the moderating role of land tenure approval (LTA), nonagricultural income (NAI), agricultural mechanisation (AMC), and agricultural production efficiency (APE). There are three major findings. Firstly, in the main grain‐producing areas (MGPA), part‐time labour outflow alone is positively associated with arable land abandonment, while in the main grain‐consuming areas (MGCA), only off‐farm labour is directly related; there is no significant relationship between labour outflow and arable land abandonment in grain production and marketing balance areas (GPMBA). Secondly, part‐time labour does not necessarily lead to reduced levels of mechanisation, although lower APE emerges as an important factor in promoting arable land abandonment. Thirdly, the relationships between off‐farm labour/part‐time labour and arable land abandonment are moderated by LTA in both MGPA and GPMBA, while the moderation effect exists only in the case of part‐time labour in MGCA and GPMBA. We conclude that policies and measures in relation to agriculture and abandonment should be formulated differently for different regions.
