Tea is one of the leading beverage crops cultivated in Bangladesh, expanding rapidly in northern districts and forcing land use change. This study aims to decipher the expansion of tea cultivation and land dynamics transformation to tea land areas in the northern region of Bangladesh by using Landsat 5 TM and Landsat 8 OLI/TIRS surface reflectance images. The supervised support vector machine (SVM) method was used for classification purposes, resulting in three classified maps for the years 2004, 2013 and 2022, having overall accuracies of 91.43 %, 98.67 %, and 98.48 % and kappa coefficients of 89.51, 98.37, and 98.13, respectively. The images were classified into six land use classes: agriculture, tea cultivation area, settlement, waterbody, bare land, and forest. Land transformation results reveal that overall tea land increased by 41.08 % from 2004 to 2022, experiencing a downward trend during 2004–2013, while from 2013 to 2022, a dramatic rise of 70.01 % (equal to 4683.60 ha) tea cultivation area was found in Panchagarh district. The bare land was among the most highly transformed land classes into tea plantations, followed by the forest area. This study provides evidence of transforming underutilized land class into a profitable land use practice, i.e., tea plantation. Thus, cutting-edge technologies would be imperative in land transformation detection for sustainable land management and policy implications for the sustainable development of small landholding livelihoods and the tea industry.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"18 ","pages":"Article 100703"},"PeriodicalIF":2.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142748694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The history of the piñon nut industry is reconstructed from its inception in the mid-19th century in the New Mexico Territory to its heyday in the early 20th century until consumption began to decline in the mid-20th century. Additionally, this paper provides some suggestions for reviving this iconic Southwestern American food. The commercial harvest of piñon nuts primarily involved Native and Mexican Americans. While the economic benefits of piñon nut harvesting were significant, the work was often dangerous, with reports of deaths due to exposure, accidents, and violence. Piñon nut production varied yearly due to the trees’ masting behavior, where trees produce large seed crops intermittently. Although there was considerable interest in cultivation during the early 20th century, slow growth and delayed nut-bearing limited cultivation efforts. Piñon nuts were popular throughout the United States in the late 19th and early 20th centuries, gaining popularity, especially among immigrant communities in New York. In 1918, Fannie Spitz patented a piñon nut-shelling machine, significantly improving processing efficiency and impacting the industry by enabling quicker and more effective removal of kernels. Shelled piñon nuts were now sold for consumption out of hand and also for use in candy production. Farmers experimented with feeding hogs and chickens piñon nuts. However, this practice did not become widespread due to the availability of cheaper corn. Piñon wood was also valued for its use as firewood and in mining as props, though it had limited application as lumber for railroad ties. At the same time, smaller piñon trees gained popularity as Christmas trees. Piñon resin was chewed and also used medicinally in salves. By the mid-20th century, piñon nuts lost popularity to peanuts (<em>Arachis hypogaea</em>), which were marketed more aggressively and produced in higher quantities at lower prices. The piñon industry has struggled with crop variability, low supply, and high prices. Still, it might be revived with improved marketing, working cooperatively and through the construction of a strategic reserve to ensure a steady supply of piñon nuts every year, through both good and bad harvests.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"18 ","pages":"Article 100705"},"PeriodicalIF":2.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142748695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study modeled the future suitable habitats of twelve key multipurpose tree species (MPTS) in Benin under two climate scenarios, Shared Socioeconomic Pathways 245 (SSP245) and 585 (SSP585), based on a 2070 horizon. The research focused on peri‑urban areas (Cotonou, Abomey, Savalou, Parakou, Natitingou, and Kandi) and the protected areas network in Benin. We evaluated environmental variables influencing MPTS distribution, projected habitat changes, identified hotspots, and compared impacts on native versus non-native species. Four modelling algorithms—Generalized Additive Models, Generalized Linear Models, Maximum Entropy, and Random Forest—were used. Climate factors, particularly isothermality (Bio3) and annual precipitation (Bio12), predominantly influenced the distribution of the studied species. The models performed well, with a mean Area Under the Curve (AUC) of 0.88 and a mean True Skill Statistic (TSS) of 0.64. Projections indicated a decline in suitable habitats for 67 % of species, minor changes for 8 %, and increases for 25 %. The effectiveness of protected areas was mixed, with species showing varied responses. Savalou and Abomey peri‑urban areas emerged as key conservation hotspots, underscoring the need to shift conservation focus to these areas. Native species showed greater resilience to future climate conditions, emphasizing the importance of native species and species-specific conservation strategies under changing climates. These findings are relevant for promoting MPTS in Sub-Saharan Africa for sustainable ecological and socio-economic development.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"19 ","pages":"Article 100744"},"PeriodicalIF":2.7,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study examines the economic implications of Kauri Dieback, affecting the emblematic kauri trees located in the Waitākere Ranges Park in New Zealand, on the local, regional, and national economy through impacted recreational services. Using a risk-assessment framework integrating components of a probabilistic Cost-Benefit-Analysis (CBA), we investigate the impact of a Kauri Dieback outbreak on recreation and related spending. We assess costs based on protection management plans and expected benefits by considering the avoided economic losses from a probable park closure. Our research introduces a novel element by calculating the minimum probability of a park closure that would make protection measures cost effective. These probability thresholds can then be compared with the expert-elicited probabilities of a park closure to economically justify protection measures. A sensitivity analysis examines key assumptions, including the consideration of the indirect and induced impacts from a potential outbreak using economic multipliers. Findings show a low threshold probability range (0.2–8.9 %) for cost-effective interventions under different plausible scenarios. The scenario considering a high expenditure per visitor yields the highest net benefit (NZ$5 billion for a one-year closure), while the lowest net benefit (NZ$76 million for a one-year closure) is associated with the lowest counterpart. It underscores the need for strategic investments to protect kauri trees in a complex economic context, providing valuable insights for policymakers and the community.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"19 ","pages":"Article 100742"},"PeriodicalIF":2.7,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143128467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Remote sensing data was used to map areas prone to forest fires based on factors such as land use/cover type, terrain, and anthropogenic activities. These risk zones were incorporated into the GIS routing decision support system, enabling the generation of optimal routes from fire stations to fire risk zones and reported fire cases. System testing demonstrated the SDSS's capability to provide optimum routing options targeting fire risk hotspots and reported incidents within the plantations. The SDSS facilitated the identification of optimal routes to mitigate transportation costs and provided insights into spatial patterns of fire vulnerability, revealing areas that may be inaccessible within the optimal timeframe. This highlighted the necessity of establishing additional fire stations in high-risk regions to enhance rapid response times.

In Bangladesh, studies have addressed the vulnerability of coastal populations, but they often overlook the Sundarbans mangrove forest resource-dependent communities (SMFRDCs). These marginalized groups, reliant on the forest, frequently face natural disasters such as cyclones, increasing their vulnerability. This study seeks to assess the extent of vulnerability among SMFRDCs and uncover the critical risk factors contributing to it. This cross-sectional survey was conducted in three southwestern coastal districts of Bangladesh: Satkhira, Khulna, and Bagerhat. Data were collected from 782 SMFRDCs in three <em>Upazila</em> (sub-district) of selected coastal districts using a structured interview schedule (SIS) and following a multistage stratified random sampling approach. The data were analyzed using IBM SPSS Statistics v27 for Windows. A one-sample binomial test was performed to assess the prevalence of vulnerability. Additionally, bivariate analyses (Pearson’s Chi-square [χ²], Yates’s Correction for Continuity [χ²_Yates], Phi [<em>φ</em>], and Cramer’s V [<em>φ</em>_c]), and multivariable binary logistic regression (MBLR) were conducted to identify the associated risk factors. The findings of the one-sample binomial indicate that among the coastal <em>Upazila</em>, the vulnerability prevalence was highest in Mongla (53.4 %; 95 % CI: 47.4 % - 59.3 %). Additionally, honey collectors were found to be more vulnerable to natural disasters, with a prevalence of 60.8 % (95 % CI: 52.7 % - 68.6 %) among the SMFRDCs. The MBLR findings indicate that SMFRDCs with over 31 years of experience and involvement in multiple occupations were less vulnerable to natural disasters. Likewise, SMFRDCs with better household materials, transport, and livestock assets were less vulnerable to natural disasters. In contrast, those with medium-to-high domestic assets were more at risk. Additionally, having land and access to loans reduced the likelihood of vulnerability. SMFRDCs with better natural, physical, and political capital were also less vulnerable. The findings show that vulnerability among SMFRDCs varied by geospatial location and occupation. Socio-demographics, household resources, and livelihood capitals were key predictors of the household vulnerability of SMFRDCs. To reduce this vulnerability, it is recommended that organizations – governmental and non-governmental – work together to create comprehensive plans involving SMFRDCs in both planning and implementing disaster risk reduction strategies by addressing individual and community-level factors.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"19 ","pages":"Article 100739"},"PeriodicalIF":2.7,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
