This article first examines the theoretical applicability of resilience in the context of cultivated land use systems and subsequently introduces a specific concept of cultivated land system resilience (CLSR). Focusing on the middle reaches of the Yangtze River, a major grain-producing area in China, the study constructs a measurement system that encompasses five dimensions: endowment of production, socioeconomic factors, scale structure, ecological pressure, and food security. This system is used to evaluate the spatio-temporal evolution and influencing mechanisms of CLSR in the region from 2001 to 2020. The results indicate that the level of CLSR increased by 7.2% overall and exhibits a distinct spatial pattern, with high-value areas expanding from the center to the surrounding regions. Furthermore, CLSR shows a positive spatial correlation with rising levels of agglomeration. The spatial heterogeneity of CLSR is influenced by the interaction of various factors, resulting in a partially nonlinear two-factor enhancement. The influence of each factor varies between different time periods, shifting from ecological pressure to scale structure, ultimately affecting food security. Thus, the resilience perspective offers greater explanatory power to identify key vulnerabilities in the regional cropland system. This approach can improve the efficient allocation of cropland resources and promote sustainable and healthy development at the regional level.</p>\u0000 </div>","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"35 17","pages":"5425-5438"},"PeriodicalIF":3.6,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142405347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Visible and near-infrared (Vis-NIR) near-Earth remote sensing spectroscopy has become an effective alternative to the traditional time-consuming and costly methods due to its high-resolution and nondestructive application, but it is vulnerable to the redundancy of spectral information and the overlap between bands. This study delves into the potential of optimal spectral parameters for estimating SOC in arid lakeside oases, using Bosten Lake in Xinjiang, China, as a focal point. Soil samples (0–10 cm, 10–20 cm, 20–30 cm, 30–40 cm) were collected, and their SOC content and hyperspectral reflectance were measured. The spectral data underwent preprocessing techniques, including continuum removal (CR), standard normal variate (SNV), and continuous wavelet transform (CWT). SOC content was predicted using back propagation neural network models constructed based on one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D) correlation coefficients. Results showcased the effectiveness of the CWT method in accentuating potential spectral information and enhancing variable correlation. Among the indices, 3D exhibited the highest performance (<i>R</i>² = 0.82, RPD = 2.02 for TDI-1 at 0–10 cm; <i>R</i>² = 0.85, RPD = 2.28 for TDI-2 at 10–20 cm; <i>R</i>² = 0.83, RPD = 2.24 for TDI-1 at 20–30 cm; <i>R</i>² = 0.86, RPD = 2.53 for TDI-4 at 30–40 cm), followed by 2D and then 1D. These insights offer guidance for future strategies in hyperspectral data preprocessing and spectral index determination, facilitating SOC spatial distribution mapping and advancing sustainable agricultural planning. They also have implications for determining the spatial distribution of SOC content based on spatial interpolation, which would contribute to regional agricultural planning and sustainable development.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"226 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142385781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is still a limited understanding of these specific factors, particularly in the context of the Czech Republic. This study investigates the perceptions and determinants influencing the adoption of SCPs among farmers in the Czech Republic. We analyzed 358 randomly selected farm households using probit and multivariate probit models. Our results show that a significant number of farmers perceive soil degradation as an important problem, attributing it to factors such as low soil nutrient content, declining soil humus, water and wind erosion. The results of our analysis showed positive associations for perceived effectiveness and profitability, indicating that farmers tend to adopt practices such as minimum tillage, mulching, mixed cropping, cover cropping, and continuous soil cover when these methods are perceived to be effective and profitable. Conversely, negative associations are found for perceptions of soil degradation and education, suggesting potential barriers to adoption with higher levels of perceived soil degradation and education. The study also highlights the complex interplay of information sources on adoption, with both positive and negative trends. In light of these findings, we propose recommendations, including that awareness campaigns should be tailored to address perceptions of soil degradation, and that the use of peer networks and information dissemination from research institutions can bridge the gap between scientific recommendations and on‐farm practices. Policy makers and agricultural extension services should work together to develop targeted strategies that take into account regional differences in the factors influencing adoption and ultimately promote widespread adoption of SCPs.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"226 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142385539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a novel contribution in the form of a model-based analysis, grounded in fieldwork from the Yellow River Delta, which assesses the potential of native <i>Suaeda salsa</i> as an alternative for coastal protection. Our approach is distinctive in that it not only compares the flow velocity reduction effects of <i>S. alterniflora</i> and <i>S. salsa</i>, but also evaluates the efficacy of three distinct planting patterns in managing tidal dynamics.

This study compared pore structure characteristics in the root detritusphere of soils of contrasting texture and mineralogy subjected to &gt; 6 years of contrasting vegetation: monoculture switchgrass and polyculture prairie systems. Soil samples were collected from five experimental sites in the US Midwest representing three soil types. Soil texture and mineralogy were measured using a hydrometer and x-ray powder diffraction, respectively. The intact cores were scanned with x-ray computed micro-tomography to identify visible soil pores, biopores, and particulate organic matter (POM). We specifically focused on pore structure within the detritusphere around the POM of root origin. Results showed that the detritusphere of coarser textured soils, characterized by high sand and quartz contents, had lower porosity in the vicinity of POM compared with finer textured soils. POM vicinities in finer textured soils had high proportions of large (&gt; 300 μm diameter) pores, and their pores were better connected than in the coarser soils. Lower porosity in the outer (&gt; 1 mm) parts of the detritusphere of switchgrass than of prairie suggested soil compaction by roots, with the effect especially pronounced in the coarser soils.

Although there have been some previous studies on the stoichiometry of biocrust subsoil in grazing systems, further research is needed to assess the effects of varying grazing intensities. Four grazing gradients were established to investigate the change mechanism of biocrust subsoil stoichiometry under grazing conditions, considering its seasonal response. These findings revealed that biocrusts' coverage and their chlorophyll content showed a parabolic trend of increasing and then decreasing with the increase in grazing intensity. At the same time, their standard response thresholds to grazing intensity ranged from 2.67 to 5.33 sheep/ha. Moreover, the premise that the biocrust is damaged by grazing trampling has become a consensus; our study found that the biocrust still played an important role, although its structure was destroyed because of its greenness (BG) increased. The influence of grazing intensity on the biocrust subsoil stoichiometry is unquestionable; in addition, they are influenced by a combination of vegetation (10% and 19%) and environmental influences (6% and 18%). Furthermore, it was observed that these changes did not compensate for the reproduction and development of biocrusts in grazing-induced trampling damage. In this study, the integrated consideration of biocrusts into the grazing system fully affirmed its essential role.

This study investigates the relationship between ES multifunctionality and HWB in rapidly urbanizing regions, using the Yangtze River Delta Urban Agglomeration in China as a case study. We quantified ES multifunctionality with the Gini-Simpson Diversity Index and identified ES multifunctional types using the bundle approach. We also calculated both the HWB mean score and HWB evenness score with the improved radar chart method, examining their relationships with ES multifunctionality through Spearman correlation analysis and the Kruskal–Wallis rank-sum test. Results showed that (1) ES multifunctionality exhibited varied relationships with HWB indicators, but overall showed significant negative associations with both HWB mean score and HWB evenness score.

(3) HWB mean score and HWB evenness score were generally higher in the peri-urban bundle while lower in the agriculture and forest bundles. Our findings suggest that peri-urban landscapes can provide relatively higher and more balanced levels of HWB in urban agglomerations.
