Furthermore, Bivariate Spatial Autocorrelation Analysis examined the interplay between ESs supply and demand, while an index of supply–demand coordination assessed ecological sustainability. Drawing from these analyses, ecological restoration zones were demarcated within the basin, accompanied by tailored optimization strategies that accounted for human demands, natural resource dynamics, and regional development patterns.

Mangrove ecosystems face risks from challenges such as industrial development and economic instability. In Iran, these ecosystems play a vital role in supporting the livelihoods and well-being of local communities, including the provision of edible aquatic resources, honey production, and fodder for livestock. This research seeks to identify the variables influencing the duality of ecosystem well-being and human well-being (HWB) to contribute to sustainability commitments and support the HWB of local communities. To better understand the effects of mangrove ESs on HWB, Structural Equation Modeling (SEM) and the Social Progress Index have been employed, examining the impact of community perceptions of these services on their attitudes. Ultimately, this research aims to clarify the complexities in the relationship between ESs-HWB of local communities through a structured questionnaire. Data were collected from 400 households across 45 urban and rural settlements. Overall, the results indicated a negative association between mangrove ESs and HWB, however, a positive perception of these ESs was find, which is linked to a favorable community attitude toward mangrove conservation. We used the FIMIX technique to revealed hidden heterogeneity in the data, and the results showed that this relationship varies across regions, influenced by cultural differences and dependence on natural resources. Local factors such as livelihoods and awareness of ESs also play a significant role in shaping community attitudes and behaviors. Our finding suggest that management programs should emphasize awareness-raising and environmentally compatible economic development, particularly through creating added value for local mangrove products, which simultaneously enhance mangrove sustainability and local HWB.</div></div>","PeriodicalId":54898,"journal":{"name":"Journal for Nature Conservation","volume":"84 ","pages":"Article 126827"},"PeriodicalIF":2.2,"publicationDate":"2025-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143180960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Assessing the natural resource dependence (NRD) and livelihood vulnerability of rural households in disaster resettlement regions is crucial for addressing current ecological and livelihood concerns. It serves as a useful guide for future sustainable development. Drawing on data from 657 rural questionnaires in Ankang Prefecture, this article conceptualizes and measures NRD and livelihood vulnerability at the household level. Based on a comparative analysis of NRD and livelihood vulnerability across various types of rural households, ordinary least squares (OLS) regression models were used to investigate the influence of NRD on livelihood vulnerability. The results show that: (1) the NRD kernel density curves of relocated households are steeper than those of non-relocated households, indicating less fluctuation in dependence; (2) the livelihood vulnerability of relocated, voluntarily relocated, and newly relocated households are significantly higher than that of non-relocated, involuntarily relocated, and early relocated households; (3) NRD is significantly and negatively associated with livelihood vulnerability, with energy dependence showing a similar response. Our study indicates that rural households’ dependence on natural resources can effectively reduce their own livelihood vulnerability. Therefore, it is recommended that policymakers improve the NRD of rural households by implementing sustainable resource management strategies, promoting diversified livelihoods, and providing targeted policy support.</div></div>","PeriodicalId":54898,"journal":{"name":"Journal for Nature Conservation","volume":"84 ","pages":"Article 126832"},"PeriodicalIF":2.2,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143181891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We considered five life stages (seedling, sapling, juvenile, immature adult, and reproductive adults), in which seedling and sapling were fitted as regenerants. Recruitment failure occurs mostly in sites in agricultural and intensive pasture areas, in which habitats with a low rate of chronic anthropogenic disturbance showed a higher density of regenerants. In these habitats, marked by recruitment bottlenecks, populations are likely to become locally extinct. The fruit harvesting levels did not affect the density of regenerants.

Wuchang Lake, a gated-controlled lake in the middle and lower Yangtze River floodplain, is an important wintering site for waterbirds on the East Asian–Australasian Flyway. Lake water level control during the wintering period in 2021–2022 was different than that in 2022–2023. We collected waterbird data from two wintering periods, based on functional alpha and beta diversity and waterbird functional groups, we analyzed the impact of water level regulation on wintering waterbird communities. By remote sensing data of foraging habitats we further analyzed the effects of changes in habitat structure to waterbird communities at different water levels. The results showed that during high lake water level, the numbers of deep water swimmers feeding on fish (G3) and swimmers feeding on seeds (G7) increased significantly, the number of large wading birds feeding on fish (G2) decreased significantly. And high lake water level decreased functional richness indices (FRic), functional evenness indices (FEve) and functional divergence indices (FDiv). Among them, in January and February 2023, the functional divergence indices significantly decreased. Functional beta diversity analysis showed that the total dissimilarity among communities decreased significantly in 2022–2023, with the functional nestedness component increasing significantly in October and February and the functional turnover component decreasing significantly in October, December, and February. Generalised linear mixed models (GLMM) showed that high lake level expanded the water area and favored the habitat of swimming birds, while decreased mudflat area, limiting the habitat space for wading birds. In contrast, lake water level decreased to increase the mudflat area and promoted the differences among communities.

Any change in the ecosystem affects the cultural identity and social stability of the resident community. The present study highlights the link between individual cognition and behavior, their conservation value on cultural services, and how this is supported by the economic valuation approach in the Parambikulam Tiger Reserve (PKMTR) of Kerala, India. The study provides evidence of cognitive behavior that contributes to the conservation of an ecosystem by considering both natural (Kannimara teak) and cultural heritage (traditional practices followed by the resident community). The cognitive value of both the Kannimara teak and the cultural heritage from the rituals in the temples, analyzed using qualitative methods, highlights that one’s environmental view plays a key role in influencing general beliefs and behavior, which in turn results in the conservation or degradation of an ecosystem service. The economic value of natural heritage was analyzed using the contingent valuation method. While the mean willingness to pay by the resident communities for natural heritage was found to be Rs 172/household/year, the total value for cultural heritage in PKMTR was estimated at Rs 55,950/year, indicating immense conservation potential for both natural and cultural heritage.
