To elucidate how differences in land ownership affect farmers' ecological protection behaviors on owned versus leased land, this paper develops a conceptual model linking land leasing with the adoption of sustainable agricultural practices, which is grounded in the duration of land contracts. An empirical analysis was conducted using data from 71373 samples collected through the China National Agricultural Product Cost and Benefits Survey (CNACBS) from 2004 to 2022. The results indicate that farmers with a greater proportion of leased land are less likely to adopt ecological farming practices. Specifically, leasing land significantly increases the use of fertilizers and pesticides by maize growers, whereas the use of manure decreases. However, land title certification can effectively mitigate the inhibitory effect of leased land on farmers' farmland ecological protection behaviors. Additionally, farmers with experiences of tenancy insecurity, due to past instability in land tenure and policy changes, exhibit a more conservative approach to long-term investments and continuous management of land. Compared with those in plains regions, farmers in mountainous areas are more inclined to adopt strategies that excessively use fertilizers and pesticides to maximize short-term economic benefits.</div></div>","PeriodicalId":17933,"journal":{"name":"Land Use Policy","volume":"153 ","pages":"Article 107547"},"PeriodicalIF":6.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research proposes a Green Infrastructure (GI) planning approach to enhance flood control and resilience in the flood-prone Yeoksam-dong region of Gangnam, Seoul, South Korea. A mixed-method approach was employed, incorporating both residents’ preferences and hydrological simulations using the Stormwater Management Model (SWMM) to assess the effectiveness of various GI controls. Key GI co-benefits were identified through importance–performance analysis (IPA) and fuzzy weight rankings. Based on these, three GI scenarios were developed and evaluated for their flood mitigation potential. Scenario 1 (infiltration trench, rain garden, and rain barrel) emerged as the most effective, reducing surface runoff by 18.56 % and achieving the best cost-benefit ratio of 1.01 over a 10-year period. Scenario 2 (bio-retention, pervious pavement, and green roof), while less effective in terms of flood mitigation, may still offer ecological and social co-benefits. The study also conducted a sensitivity analysis, which confirmed Scenario 1’s robustness across various levels of imperviousness, making it a highly adaptable solution for urban settings. This research highlights the importance of community engagement in GI planning and demonstrates how integrating hydrological performance with socioeconomic benefits can enhance urban resilience. By aligning with the 4Rs of resilience; robustness, redundancy, resourcefulness, and rapidity, this study provides actionable insights for policymakers and urban planners seeking cost-effective, scalable solutions for flood-prone areas. The findings underscore the value of multifunctional GI controls in not only reducing flood risks but also promoting long-term sustainability and community well-being.</div></div>","PeriodicalId":17933,"journal":{"name":"Land Use Policy","volume":"153 ","pages":"Article 107535"},"PeriodicalIF":6.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We quantified tropical tree cover dynamics across eight regions in four tropical countries, examining how these patterns relate to FT and how they vary between climates and forest types. Each country represented a different stage in the FT trajectory. We combined Landsat-derived time-series from 1990 to 2020 with Sentinel-2-based land cover classification to distinguish between mature natural forests (MF), second-growth forests (SF), tree plantations (TP), and their dynamics. During this period, 50 % of MF was lost, while tree cover gains averaged 16 % across regions; SF contributed 23 % and TP 12 % of total tree cover by 2020. SF steadily increased, yet its average lifespan was only 10 years, limiting its ecological contributions compared to MF. The studied regions followed the theoretical FT trajectory: the Ghanaian regions were in early transition (pre-inflection), Mexican regions were in late transition (pre-inflection), and the Australian and Brazilian (São Paulo state) regions were in post-transition (post-inflection). Evaluating FT while including or excluding TP results in different conclusions about the FT trajectory of a region or country. MF was lower in dry (from 55 % in the 1990s to 23 % in 2020) than in wet (from 73 % in the 1990s to 35 % in 2020) forest regions. SF gains were higher in dry (31 %) than in wet (23 %) regions, though SF increases did not compensate for MF loss, resulting in reduced biodiversity and ecological functioning. Hence, halting deforestation and protecting young forests are equally crucial. Evaluating FT excluding TP and quantifying SF persistence may have far-reaching consequences for how to evaluate tree cover by not only evaluating tree cover quantity, but also tree cover quality. Our findings can inform policymakers to design smart policy mixes that sequence the right policy instruments at the right time. Local people must participate in forest restoration strategies and issues of equity, justice and power imbalances must be addressed to facilitate FT. Dissecting FT increases our understanding of the underlying forest cover dynamics, which can lead to better policies for protecting local people`s livelihoods, halt deforestation, and facilitate FT to restore the natural world upon which people`s lives and society depend.</div></div>","PeriodicalId":17933,"journal":{"name":"Land Use Policy","volume":"153 ","pages":"Article 107545"},"PeriodicalIF":6.0,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143715955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of the new eco-schemes, alongside the AECM, raises questions regarding 1) the acceptance of eco-schemes by farmers, and 2) the impact on adoption of AECM. Would farmers prefer to continue with familiar measures or opt for the new, less restrictive, and shorter eco-schemes? To address these questions, two discrete choice experiments (a stated preference method) were conducted on a sample of 360 farmers with previous AECM experience. These experiments focus exclusively on grassland-related measures, as they are available in both contract forms, eco-schemes and AECM. The results reveal a general aversion to voluntary agri-environmental measures. However, farmers are more inclined to implement the new eco-schemes rather than the more familiar AECM, especially when the compensation of the latter is conditional on the environmental results.

Studies on acquisition costs are non-existent in the peatland scientific literature, while the sale price of peatlands could increase restoration costs, hampering the feasibility of operation works. Given the need for spatially explicit information for restoration planning, we use the first stage of the hedonic prices method to provide a model that measures the price of French peatlands and its determinants, at a national scale. Real peatland sales from the DVF+ database (Cerema) are exploited. The parcels selected in the model are distributed along a gradient of elevation, state of degradation and intensity of land use. Predictions of peatland prices are then made in the Cotentin-Bessin and jurassian massif regions to check the validity of the model. The average peatland price is 3014 €/ha but it varies greatly between regions. The main results indicate that intensive land use (crops) and increasing slope raise the selling price, while elevation, increasing distance to settlement and moor land use lower it. The prediction results are encouraging for a nationwide use of peatland prices in restoration planning programs. This study will also help get a better understanding of implications of peatland acquisition in restoration and total costs.

However, previous studies problematized the double impacts of urban expansion on vegetation growth at a specific time, ignoring the dynamic relationships and evolving thresholds of indirect impacts over time. Here, a novel three-dimensional (3D) conceptual framework was proposed to explain the dynamic relationships between urban expansion and vegetation growth across China’s urban agglomerations (UAs) from 2000 to 2021. The corresponding thresholds of indirect impacts of urban expansion on vegetation growth were also quantified. Double-S thresholds of vegetation growth responses to urban expansion were found over time, including urban expansion intensity (UEI) and vegetation index (VI) thresholds. These thresholds showed strong climate dependence across climate zones, with higher UEI thresholds in humid zones and lower VI thresholds in semi-arid zones. Human activities explained higher contributions than climate change in the variations in double-S thresholds of indirect impacts. Based on above analysis, a sustainable land management framework was proposed to promote land restoration by integrating the dynamic impacts and double-S thresholds of urban expansion on vegetation growth. Furthermore, zoning management strategies were provided for precision land restoration across climate zones, including reducing negative direct impacts and enhancing positive indirect impacts.
