In Myanmar, agroforestry-based community forests (ACFs) have been implemented since 2013 to reforest areas encroached upon by agriculture in state forests. This study aimed to improve ACF implementation by analyzing farmers’ perceptions of the contributions of ecosystem services, including provisioning, regulating, supporting, and cultural services, to their livelihoods. We surveyed 291 households by using a questionnaire including closed and open-ended questions, and conducted forest inventories across 42 sample plots. The methods for analyzing social data included descriptive statistics, partial proportional odds model, and qualitative co-occurrence analysis. With regard to forest data, we analyzed species composition, above-ground biomass, and canopy cover. Farmers perceived provisioning ecosystem services as the most important, followed by regulating services. Socioeconomic factors significantly shaped these perceptions: education, particularly at secondary and higher levels, positively influenced the perceived importance of regulating services, whereas household income negatively influenced the perceived importance of cultural services. In contrast, larger landholdings were linked to greater perceived importance of cultural services. Despite the high perceived importance of provisioning services, the actual contribution of ACFs to provisioning services and their economic potential remained low, highlighting the need to enhance these ecosystem functions. We discuss options for improving provisioning services as well as other ecosystem services based on farmers’ needs and values. Among these options is the incorporation of fast-growing native tree species that can generate both short- and long-term income through timber and non-timber forest products. Overall, this study demonstrates that applying the ecosystem services framework to assess farmers’ perceptions and the current contributions of ACFs provides valuable insights into their limited socio-economic benefits and their ecological role in supporting environmental stability.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"25 ","pages":"Article 101272"},"PeriodicalIF":2.9,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147850247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ethnobotanical data were collected from 140 informants, stratified by gender, age, and education, using semi-structured questionnaires to document plant uses, perceived threats, and conservation strategies. Vegetation surveys were conducted in 31 plots across protected areas (17 plots, 900 m²) and agroforestry systems (14 plots, 2500 m²), with all individuals measured for basal diameter, diameter at breast height, total height, and pruning intensity. Generalized linear mixed models (GLMMs) and generalized linear models (GLMs) were used to test the effects of sociodemographic characteristics on plant use and perceived benefits, while Fisher’s exact tests were used to examine associations with perceived population trends. Population structure was analyzed through diameter-class distributions, supplemented by slope, permutation index, and consecutive class quotients. Leaves were the most exploited organ (Index Value of Organs = 72.3%), primarily for food. Most informants (75%) reported a population decline due to drought, low regeneration, and intensive exploitation. Vegetation data revealed higher tree densities in protected areas, but consistently low juvenile abundance and high pruning intensity across land-use types (69.9 ± 27.6%–71.9 ± 32.2%). Diameter-class distributions showed unimodal structures dominated by medium-sized individuals, indicating limited recruitment. These findings highlight the dietary and medicinal importance of this species while underscoring threats from intensive pruning and poor regeneration.

We used structural equation modeling to investigate the mediating role of understory plant diversity in African mahogany plantations on the effect of plantation traits (size, age, isolation) on arthropod diversity and plant herbivory rates. We found lower herbivory rates in larger plantations but no direct effect of plantation age and isolation on herbivory rates. However, we found indirect effects of plantation traits on understory plant herbivory rates, mediated by effects on plant species richness and its influence on phylogenetic diversity. Plantation age, size, and isolation indirectly reduced herbivory rates by increasing species richness. Phylogenetic diversity was positively associated with species richness and thus was also directly negatively associated with herbivory rates. Altogether, our findings underscore the importance of considering plantation traits and their spatial context in managing biodiversity and ecosystem services in human-modified tropical ecosystems. The biotic processes demonstrated in the understory communities of forest plantations are similar to those found in native forests.

Guided by a social-ecological systems and value chain framework, 252 semi-structured interviews and nine focus group discussions were conducted in total of 36 locations with harvesters, processor-traders, and consumers. Key findings are that bamboo continues to be harvested unsustainably, mainly from national forest lands, with cultivated sources and plantations playing a marginal role. Processing remains basic, with informal trade predominating on the roadside (33%) and markets (6%). Bamboo contributes 3448,632 FCFA (39%) to annual household incomes for processor-traders and is of secondary importance for collectors, providing 757,596 FCFA (26%) annually. Value-adding remains low, although consumers generally like bamboo products, rating them competitively, as affordable and durable but not high-quality. Social-ecological factors, including the nature of the resource system, governance, characteristics of users in the chain, and their interactions contribute to the overexploitation of bamboo resources. These findings suggest research, conservation, development and policy interventions are needed to improve governance: developing and enforcing a dedicated bamboo policy, improved resource management through knowledge and capacity building, promoting higher-value bamboo products to increase value and incomes, cultivating bamboo, particularly on degraded land to support restoration and carbon trading, could ensure long-term socio-economic and ecological sustainability of the chain.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"25 ","pages":"Article 101264"},"PeriodicalIF":2.9,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147798051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We bridge this policy and academic gap by analyzing panel data from 24 African countries between 2000 and 2022 using fixed and random effects econometric models. The analysis revealed that domestic credit to the private sector significantly accelerates deforestation. This suggests that expansionary financial policies without conditions for forest sustainability could intensify deforestation in Africa. However, the impact of institutional quality on deforestation presents mixed effects. While government effectiveness reduces forest loss, other indicators, such as political stability, voice and accountability, control of corruption, and the rule of law, are paradoxically associated with increased deforestation in Africa. Based on these findings, the study proposes a \"Green Domestic Credit\" model that links financial expansion with forest safeguards, including support for climate-smart agriculture. The study highlights the importance of reassessing African-specific financial expansionary policies and environmental sustainability for promoting inclusive growth.

Fortunately, urban forests are an effective solution to these problems. However, the differential capacity of various forest types to purify air pollutants and modulate human comfort remains inadequately quantified along the urban-rural transect. Thus, this study quantified the spatiotemporal heterogeneity in forest-mediated mitigation of air pollutants and modulation of human comfort along the urban-rural transect by field measurement. The results revealed that the capability of urban forests to mitigate pollution and enhance human comfort depended collectively on their position on the transect, season, and forest type. Along the urban-rural transect in Nanchang, the atmosphere purification capacity decreased sequentially from suburban to exurban to urban core regions. Seasonally, purification capacity was lowest during summer. Regarding forest types, coniferous forests were the primary source of negative air ions in urban areas, effectively improving air quality in both suburban and exurban regions. In contrast, evergreen broadleaf forests were particularly effective at enhancing urban air quality and thermal comfort. These context-dependent results suggest: (1) Increasing broad-leaved forest coverage in densely populated urban cores to prioritize urban heat island (UHI) mitigation; (2) Prioritizing coniferous forests in industrially active suburban areas for targeted air pollution; and (3) Focusing on expanding mixed-species forests in exurban regions to maintain the ecological advantage of high negative air ion concentrations. These findings provide empirical evidence for optimizing urban forest configurations through strategic spatiotemporal zoning and conifer-broadleaf ratio adjustments to maximize air quality regulation services.

Here, we systematically reviewed 111 publications and conducted a meta-analysis of 59 studies to develop a global synthesis of teak-specific biomass and C accounting parameters. The compiled dataset is geographically uneven, with most studies originating from Asia and comparatively limited data from Africa and Latin America. Our results revealed that stems account for the majority of total tree biomass (66.9 %), followed by branches (16.6 %), roots (12.8 %), and foliage (≤ 3.7 %), indicating predominant C allocation in long-lived woody components. The pooled mean BEF was 1.66, and the mean RSR was 0.23. Mean C concentrations were 48.9 % in stem biomass, 44.2 % in understorey vegetation, and 42.8 % in litter. However, heterogeneity was consistently high across studies, indicating substantial variability associated with differences in site conditions, stand characteristics, and methodological approaches. These findings demonstrate that uniform application of BEF, RSR, and CCF can introduce systematic bias in teak C estimates. We recommend the adoption of species- and site-specific parameters, inclusion of coarse woody debris, and standardized, depth-explicit soil protocols to improve accuracy and comparability.
