The circular economy presents a vital approach to enhancing climate resilience and sustainable land management by minimizing waste, optimizing resource efficiency, and promoting ecosystem restoration. Effective regulatory innovations play a crucial role in facilitating this transition, ensuring policies support circularity, ecological sustainability, and the rehabilitation of degraded ecosystems. This study adopts a comprehensive framework incorporating the fuzzy Analytical Hierarchy Process (AHP) method to assess and rank factors and sub‐factors essential for regulatory enhancement. Through fuzzy AHP analysis, six key factors and 24 sub‐factors influencing the circular economy were assessed. The findings reveal that economic incentives (R2), the legislative framework (R1), and innovation support (R4) are the most critical factors driving circular economy progress. Additionally, taxation strategies (R21), policy orientation (R11), and legal transparency (R12) emerged as the top‐ranked sub‐factors. By examining climate change as a key driver of land degradation, this study offers valuable insights into regulatory strategies that bolster climate resilience, support sustainable land management, and facilitate the transition toward a circular economy. The findings provide a policy‐oriented framework for enhancing regulatory structures aimed at mitigating environmental degradation and fostering long‐term sustainability.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"21 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144260105","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}

Through workshops with farmers, we identified the types of family farming and their problems, such as pests, diseases, low productivity, land degradation, and lack of resources. The solutions proposed include value‐added projects, better financing, and improved farmer organization. A land suitability analysis for cacao, coffee, maize, and mango revealed that these crops are often grown in low or medium‐suitability areas, causing degradation and low profitability. Significant associations between land suitability and farming types were found. Farmers agreed on the utility of relocating or switching crops based on suitability results. This study provides essential insights for policymakers, researchers, and practitioners to develop strategies for transitioning family farming toward sustainability. The research ensured its findings were grounded in local knowledge by directly involving farmers. The participatory framework empowered farmers as co‐creators, enhancing the relevance and feasibility of proposed interventions. The study provided actionable insights bridging science, policy, and practice. Its scalable methodology offers a valuable model for addressing similar global challenges in marginalized regions.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"17 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144252275","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}

{"title":"Social Dynamics of Perceived Intangible Values Under Ecological Restoration Among Rural Inhabitants in Yan'an, China","authors":"Xinran Zheng, Yu Liu, Yuehan Dou","doi":"10.1002/ldr.5626","DOIUrl":"https://doi.org/10.1002/ldr.5626","url":null,"abstract":"Ecological restoration has been considered and implemented as an effective approach to reverse land degradation, particularly in vulnerable drylands. While there has been a large body of research focusing on the ecological and economic benefits of these projects, few studies have focused specifically on the intangible socio‐cultural values like cultural heritage, identity, and social cohesion in these areas. The difficulty in quantifying these values lies in their subjective perception among individuals and keep changing dynamic social contexts. Therefore, it remains unclear about how local inhabitants perceive the intangible cultural and social benefits provided by dryland ecosystems and how this perception impact community well‐being. This study employs the Cultural Ecosystem Services (CES) framework to evaluate how rural communities perceive the intangible benefits under ecological restoration. We re‐classify the commonly used ten types of CES into four main categories, auto‐responsive/intrinsic, behaviors, meanings and personal. We conducted 466 semi‐structured household interviews across 17 representative villages in Yan'an, China's Loess Plateau region. Through latent class analysis, we identified three distinct perception patterns of CES. Results revealed universal recognition of all CES types, with education and income significantly influencing their perceptions. Certain landscapes like grasslands and villages strongly shaped “sense of place” and social connections, while wetlands and waterfalls had minimal impact. Social engagement, particularly employment, enhanced CES recognition, whereas religious activities showed limited influence. This exploratory study examines the social dynamics of perceived intangible values in dryland ecosystem restoration. Our innovation lies in applying the CES framework to assess these values in dryland areas, using latent class analysis to identify three perception categories linked to demographics, landscapes, and activities. This approach offers targeted suggestions for enhancing CES, supporting ecological restoration policies that value both nature and culture. While our study establishes a foundation, further long‐term research is needed to fully understand the relationship between CES perceptions and ecological restoration outcomes.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"25 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144237751","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}

We examined: soil pH, texture, enzyme activity, and C, N, P, K, CaCO₃ contents, Zn, Pb and Cd contamination of soils and grasses and biomass, lignin, Ca, K, P, Na contents of grasses. SOM stabilisation was evaluated through the analysis of the humic acids (HAs) composition and optical properties. In all soils, the mean C stocks ranged from 5.8 to 10.3 kg/m² and were similar to these in the reference soils, but the HAs of the brownfield soils had a more aliphatic structure and lower maturity, thus less stabilised SOM than the reference soils. High C accumulation in brownfield soils resulted from the high biomass, especially roots, of the well-adapted plants covering these soils, which were also rich in lignin, accumulated as a protection against stress. A lower SOM stabilisation of brownfield soils than of reference ones was caused by their high TMs contamination, but it differed according to the combined effects of both: the soil age (being more stabilised in older soils) and a disturbance degree (more stabilised in less disturbed industrial soils than mine ones).","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"8 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144260104","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}

In this regard, the study made use of GIS‐based multi‐criteria evaluation to determine livestock grazing suitability and degradation risks in the semi‐arid Dawa watershed, integrating five relevant biophysical parameters (land use/cover, rainfall, water accessibility, slope, and soil type) with socio‐economic indicators derived from expert informant surveys. Importantly, land use/cover classification recorded an accuracy of 98.3% (kappa = 0.97), confirming the soundness of the methodology. Among the species assessed, camels were found to have a fair share of appropriate rangelands, 72% moderately suitable, and 20% highly suitable, thus emphasizing the potential for specific management approaches targeting this species. Furthermore, with the three assembled socio‐economic variables including service accessibility (<jats:italic>β</jats:italic> = 0.65), infrastructure quality (<jats:italic>β</jats:italic> = 0.61), and market accessibility (<jats:italic>β</jats:italic> = 0.40), multiple regression analysis showed these were useful in explaining 78.9% of variance in rangeland suitability.

Previous studies have shown that aerated irrigation improves crop nitrogen absorption and utilization. However, the mechanisms behind the interaction of water and nitrogen under aerated drip irrigation and its impact on crop WUE remain unclear. This study conducted a 2‐years greenhouse experiment with spring‐summer and autumn‐winter tomato to investigate the effects of water and nitrogen coupling on leaf carbon (C) and nitrogen content, photosynthetic characteristics, plant dry matter accumulation, yield, and WUE. The experiment included three irrigation levels (W1, 50% ET&lt;jats:sub&gt;c&lt;/jats:sub&gt;; W2, 75% ET&lt;jats:sub&gt;c&lt;/jats:sub&gt;; W3, 100% ET&lt;jats:sub&gt;c&lt;/jats:sub&gt;) and three nitrogen application rates (N1, 0 kg ha&lt;jats:sup&gt;−1&lt;/jats:sup&gt;; N2, 150 kg ha&lt;jats:sup&gt;−1&lt;/jats:sup&gt;; N3, 250 kg ha&lt;jats:sup&gt;−1&lt;/jats:sup&gt;).

Under deficit irrigation, nitrogen application increased leaf carbon content by 2.17% and nitrogen content by 9.34%, improved leaf photosynthetic capacity, and increased &lt;jats:italic&gt;P&lt;/jats:italic&gt;&lt;jats:sub&gt;&lt;jats:italic&gt;n&lt;/jats:italic&gt;&lt;/jats:sub&gt; by 15.57% and &lt;jats:italic&gt;G&lt;/jats:italic&gt;&lt;jats:sub&gt;&lt;jats:italic&gt;s&lt;/jats:italic&gt;&lt;/jats:sub&gt; by 19.32%. The W2 treatment demonstrated more significant improvement compared to W1. The W3N3 treatment produced the highest plant dry matter accumulation for both tomato types, with no significant difference from W2N3 (&lt;jats:italic&gt;p&lt;/jats:italic&gt; &gt; 0.05). The W2N3 treatment produced the highest yield, 8.67%–9.13% higher than W3N3. The highest WUE occurred in W2N3 for spring‐summer tomato and W1N3 for autumn‐winter tomato. Although W1N3 had 1.02% higher WUE than W2N3, it had a 15.25% lower yield. Thus, W2N3 is recommended as the optimal water‐nitrogen management strategy for greenhouse tomato production.

Revegetation stages (0–2, 3–5, 6–8, and 9–11 years) were evaluated and compared to native tropical forest reference soils over 4 years, during the dry season. After 9–11 years, soil organic carbon (SOC), microbial biomass carbon (MBC), and enzymatic activity in revegetated soils reached levels similar to reference conditions. In early stages (0–2 years), microbial carbon was a key component, but from year 3 onward, plant‐derived organic material likely contributed to increased SOC.

These films potentially disrupt the soil structure, hinder nutrient cycling, and deteriorate soil quality. However, there is still a substantial knowledge gap in understanding how real-world waste polyethylene films (WPEFs), with varied shapes and sizes, influence soil quality and plant performance in the fields. This study investigated the effects of WPEFs on soil quality, crop growth, and changes in plastic characteristics. In situ soil incubation was conducted for 4 months under natural field conditions, and lettuce (<i>Lactuca sativa</i>) was cultivated during the period. Soils with 0%–2% of WPEFs were analyzed for physicochemical and biological properties, and lettuces from each soil condition were analyzed for growth indicators after harvest. WPEFs were examined for physicochemical changes using FTIR and SEM. After the incubation, the WPEF 2.0 treatment reduced soil bulk density significantly, from 1.03 to 0.77 g/cm³, and decreased microaggregates (&lt; 500 μm) from 22.2% to 17.2%. Meanwhile, the urease activity increased by up to 208.5% at WPEF 0.5. Although the major chemical properties remained relatively stable, lettuce growth was suppressed considerably. At WPEF 2.0, shoot height decreased by 45%, whereas total fresh and dry biomass declined by 58% and 46%, respectively. The findings suggest that the reduction in plant growth performance is driven by WPEF-induced changes in soil physical properties, particularly reduced bulk density and disrupted aggregate stability. The combined effects of soil structure and enzymatic imbalances might have contributed to the observed adverse effects on plant growth.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"20 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144260103","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}

Large-scale land-use changes disrupt hydrological processes and alter soil properties, consequently affecting the distribution of soil inorganic carbon (SIC). This study comprehensively analyzes the vertical distribution and controlling factors of SIC across one-meter profiles in various hydrogeologic units (HGUs) and land-use types (LUTs) from 100 soil profiles in the Sangong River watershed, Xinjiang, China. Our findings reveal that the alluvial-pluvial plain stores more SIC than the alluvial-pluvial fan at depths of 0–100 cm. Among land-use types, shrubland exhibits the highest SIC stock (SICD) in the topsoil (0–20 cm), while cropland shows greater SICD in deeper layers (20–60 and 60–100 cm). Importantly, HGUs significantly influence SIC distribution at depths of 0–20 and 20–60 cm, whereas the effect of LUTs on topsoil SIC is less pronounced, suggesting a dominant role of hydraulic connectivity and pedogenic processes. In contrast, LUTs significantly influence SICD in the subsoil (60–100 cm), with HGUs having a diminished effect. These results underscore the complex interplay between hydrogeological conditions and land use in shaping SIC distribution, particularly highlighting that the hydraulic connectivity governed by HGUs weakens at greater depths. Understanding these dynamics is essential for predicting SIC behavior and soil carbon balance in dryland ecosystems amidst evolving land-use and hydrological conditions.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"42 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144237394","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}
