“…These countries are attempting to boost agricultural output while depleting their natural resource base. Over the last 50 years, most regions in Iran have continued to expand and intensify their land use activities [8]. Deforestation and agricultural expansion have been the dominant patterns of land cover change over the last five centuries [5].…”

Land use change is the most important cause of disturbances in the natural environment. It increases the severity of natural disasters such as floods, dust storms, etc. Moreover, it also leads to major unnatural events such as water, soil, and air pollution and land subsidence. Land use change can take many forms in different parts of the world. The vast majority of these changes are the result of erroneous and unscientific policies that may be beneficial in the short term, but have negative long-term impact on human societies and the environment. Wrong policies lead to erroneous and short-term development and, in the long run, irreversible socioeconomic and environmental challenges. In this chapter, the process of land use change, driving forces (political decisions, technological development, etc.), causes, and effects of changes were all considered in a socio-ecological system in northeastern Iran (As a representative of the hyper-arid, arid, and semiarid regions of Iran). The discussion is captured in a framework reflecting driving forces, pressures, state of affairs, responses, and impacts (DPSIR framework).

“…For example, the UK proposed the "Green Belt Policy" to restrict the loss of cropland and China implemented the "Basic Cropland Protection Policy" to prevent the disorderly urban sprawl (Cullingworth, 2014;Wang et al, 2022b). In the fields of land use science and landscape studies, cropland is consistently a popular issue for researchers (Sarparast et al, 2020;Zhou et al, 2021). Numerous cropland-related topics have been assessed by previous studies from the micro to macro scale, including cropland conversion encroaching with urban expansion and ecological land loss (Ke et al, 2018;Tu et al, 2021), interaction with ecosystem services (Ke et al, 2019;Wang et al, 2020), displacement (Yang et al, 2020), abandonment (Yan et al, 2009;Han and Song, 2020), driving forces (Prabhakar, 2021;Uisso and Tanrıvermiş, 2021), and expansion and intensification (Zabel et al, 2019;Nzabarinda et al, 2021).…”

How Does Different Cropland Expansion Trajectories Affect Cropland Fragmentation? Insights From Three Urban Agglomerations in Yangtze River Economic Belt, China

et al. 2022

A clear understanding of cropland expansion dynamics and their effects is vital for cropland protection and food security. However, the trajectories of cropland expansion have been less discussed. This study referred to the modes of landscape expansion and assessed the cropland expansion trajectory in three urban agglomerations in the Yangtze River Economic Belt and its impact on cropland fragmentation. Specifically, we identified three cropland expansion trajectories using the landscape expansion index, namely, infilling, edge-expansion, and outlying. Moreover, the surface relief amplitude model was employed to characterize the relief amplitude effect on cropland expansion trajectories. By coupling landscape metrics (e.g., patch density, landscape shape index, the largest patch index, and aggregation index) and Spearman correlation analysis, the relationship between cropland expansion trajectories and cropland fragmentation was assessed. Results show that (1) three urban agglomerations experience cropland expansion, in which the edge-expansion trajectory is primary, followed by infilling and outlying trajectories; (2) the cumulative frequency curve indicates that infilling and edge-expansion trajectories are likely to be distributed in low topographic relief amplitude regions, while the outlying trajectory is located in relatively higher topographic relief amplitude regions; and (3) infilling and edge-expansion trajectories contribute to a significantly positive relationship with the decrease of cropland fragmentation, while the outlying trajectory has a negative relationship with cropland fragmentation. This research highlights that cropland protection policies should considerably focus on the trajectory of cropland expansion, not only request the total area of cropland in a dynamic balance.
