“…Climate change and urbanization leads to increased population movements in many parts of the world (Kam et al, 2021; Zhang, 2015), and the impact of migration on ecosystems has become a relevant topic, in particular in developing countries (Montgomery, 2008; Li et al, 2016; Ghanem, 2018; Andersson and Siegel, 2020). One of the most recent studies used global population density datasets supported by mobile phone data to track population movements in China, concluding that rural outmigration caused a large carbon sink at the national scale of China (Zhang et al, 2022a).…”

“…At 1 × 1 km scale, the trends in population density during 2000-2015) show that 57.6% of the study area has an increasing population density, mostly concentrated in areas of rapid urbanization like the Chengdu-Chongqing region, the Pearl River Delta region, the Wuhan city circle, and the Changsha-Zhuzhou-Xiangtan city cluster. In contrast, population density in the border area between Sichuan and Chongqing decreases.…”

China karst is a global hotspot of increasing vegetation cover, with ecological conservation projects being considered as the main driver. New research using global datasets also indicates that rural outmigration has contributed to increasing biomass at national scale. However, the link between rural outmigration and vegetation cover increase has not been established at regional scale, and it remains unclear as to whether increases in biomass do, in fact, improve the environmental conditions. In this study, we use local field and statistical data on population density and rocky desertification areas to study population movements and changes in aboveground biomass in relation to rocky desertification in South China karst during 2000–2017. Our results show that the urban population in this region increased by 8.3 million people between 2005 and 2015, and the rural population decreased by 4.8 million people. We find that aboveground biomass increased most in rural areas with low human pressure, and that there was an almost linear relationship between increase in biomass and rural outmigration, with the highest increase in aboveground biomass density (1.5 MgC ha−1 yr−1) observed in areas where rural outmigration was highest, and the lowest increase in aboveground biomass density (1.1 MgC ha−1 yr−1) where rural outmigration was lowest. Rocky desertification areas decreased with a higher level of rural outmigration. Using local field data, our study confirmed that rural outmigration can generate a carbon sink at regional scale by reducing rocky desertification.

“…For example, with respect to indicators, Chao et al evaluated the e-commerce labor, professional skills training, and the number of mobile phones per capita [ 55 ]. Furthermore, Zhang et al selected policy guidance, spatial compactness, and facility convenience as indicators [ 56 ], and Cao et al selected indicators such as digital infrastructure, local finance, the industrial structure, technological innovation, and educational level [ 57 ]. This study utilizes the level of digital village construction as the target layer; it utilizes institutions, human resources, and technology as sub-target layers; and it contains five criteria layers and 17 evaluation indicators.…”

Regional unevenness in the construction of digital villages: A case study of China

In regard to the comprehensive promotion of rural revitalization, the construction of digital villages is a crucial development. Because the construction of digital villages is considerably novel, the existing studies mainly focus on the theoretical aspects pertaining to the rational and practical robustness of digital villages, and with regard to regional unevenness, the number of studies that consider the current characteristics, absolute gaps, and impact mechanisms pertaining to the construction of digital villages is insufficient. Based on the regional unevenness that characterizes digital village construction, this study proposes a research framework for digital technology-enabled village construction, which integrates three major factors, namely technology, institutions, and human resources; thus, the comprehensive assessment pertaining to the level of digital village construction is enhanced. This study, which applies the aforementioned research framework, constructs an index system for evaluating the construction level of digital villages, and to reveal the characteristics pertaining to regional heterogeneity and the main influencing factors pertaining to the construction level of digital villages in China (study period; 2015–2020), it utilizes the Dagum Gini coefficient method and the spatial econometric model. Consequently, the researchers observe the following: First, the level of digital village construction in China exhibits a “W-shaped” recovery growth. Second, with respect to the regional level, the eastern region exhibits the highest level of digital village construction, followed by central and western regions; furthermore, we observe that the eastern and western regions account for the greatest intra-regional variation, and that with regard to the overall difference, the inter-regional gap represents the main causative factor. Finally, with regard to influencing factors, technology and innovation capabilities, occupational differentiation of farmers, economic development significantly contribute to the level of digital village construction, whereas fiscal autonomy exerts a significant inhibiting effect. In regard to the level of digital village construction, the research framework and results may provide a novel analytical framework for examining the main sources of regional unevenness, and it may also provide a reference for decision-making, which can influence the construction of digital villages in China as well as in other countries.

“…In addition, as a result of uncontrolled urban sprawl in the regions in question, degenerative changes in rural landscapes are gradually taking place, especially their strong homogenization [ 86 ]. Therefore, the spatial arrangement of peripheral areas of cities and suburban villages is subject to progressive, usually unfavorable transformations [ 98 , 99 ]. In this perspective, it is important to have a comprehensive understanding of peri-urban agriculture and its changes over time and space.…”

The article presents an overview of research conducted in recent years, i.e., from 2004 until now. The study has been prompted by the threat of drought over large land areas which, as a result of current climate change, may lead to desertification in dry and hot regions of the world. For the same reason, large areas of farmland are affected by drought stress. At the same time, rising air temperatures result in a significant intensification of evaporation and a gradual increase in soil salinity. This applies in particular to acres of farmland, forested areas, and green areas of cities, as well as degraded land or brownfields. As the crop stability is threatened, the food base of the world’s population is at risk and, additionally, in areas of industrial districts, people’s health is in decline. Due to these multistress conditions for plant growth, we propose a review of the current literature which addresses the possibility of counteracting these unfavorable phenomena through the appropriate selection of plant species and, when only applicable, also through specific agroecological treatments. A selection of herbaceous and woody plants useful for cultivation on saline marginal lands was proposed.
