In many cases, the planting of NTFP trees follows a transition from collecting NTFPs in natural forests to integrating the respective trees into agricultural farms with ecological and socio-economic implications. Therefore, understanding the current practice and challenges of current NTFP collection and willingness for cultivation is crucial to effectively use such land-use trajectories for FLR. In this study, we investigate the case of <em>Caesalpinia spinosa</em> (tara), whose fruits provide an emerging NTFP in southern Ecuador. Using household data from 125 households currently collecting tara fruits, we first describe the relatively young production system and then use a Heckman two-step econometric model to identify the factors influencing the expressed willingness to cultivate tara trees on farms and the area to be cultivated. The econometric model results show that the characteristics of tara collection and trade (gender of collectors, distance to the collection site, and management practices) are important determinants of tara cultivation. However, it's the household labor availability and farm characteristics that play a significant role in impacting the willingness to cultivate. The area to be cultivated was mainly influenced by household labor and economic characteristics, and tara collection and trade (management practices) characteristics. Our findings help to understand NTFP-related land-use transitions, thus supporting the design of appropriate and specific policy interventions for the sustainable development of NTFPs.</div></div>","PeriodicalId":12451,"journal":{"name":"Forest Policy and Economics","volume":"170 ","pages":"Article 103366"},"PeriodicalIF":4.0,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142756090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On one hand, the traditional use of firewood for energy results in low energy efficiency and indoor air pollution; On the other hand, it exacerbates problems such as habitat degradation for wildlife and environmental collapse. Although previous studies have explored rural energy source utilization from varies of aspects, there are still limitations in examining the impact of ecological cognition on household behaviors from a spatial correlation perspective. This study conducts a field survey of rural households in the giant panda nature reserves in Sichuan and Shaanxi Provinces to explore the impact of ecological cognition on rural households' firewood collection behaviors. By incorporating a spatial weight matrix, the study further analyzes the spatial spillover effects and the spatial heterogeneity of ecological cognition on rural households' firewood collection. The results show that: (1) ecological cognition significantly reduces firewood collection behaviors; (2) household income also decreases the consumption of firewood energy; (3) ecological cognition exhibits spatial spillover effects on rural households' firewood collection, indicating that household ecological cognition can impact surrounding households' ecological cognition and indirectly affect their firewood collection behaviors; and (4) significant spatial heterogeneity exists inside and outside the protected area. Ecological cognition significantly influences the firewood utilization of rural households within protected areas through spatial spillover effects, whereas its impact outside the protected areas is minimal. Strengthening forest ecological education to further raise ecological awareness, focusing on low-income households to provide energy subsidies, and utilizing the spatial spillover effects to enhance information dissemination channels are recommended for policy implications.</div></div>","PeriodicalId":12451,"journal":{"name":"Forest Policy and Economics","volume":"170 ","pages":"Article 103360"},"PeriodicalIF":4.0,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142756092","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}

With Norway as a case, we map economic instruments used in Norwegian forest governance and examine how they promote or constrain forests' capacity to provide different ecosystem services. Data was collected from a review of policy documents and fiscal budgets, compared with data on trends and condition of ecosystem services from Norwegian forests. Three main results are highlighted. First, the main economic instruments are markets for forest products and amenities, forestry certification schemes, and government expenditures. Second, ecosystem services traded in markets like timber (578 mill €/y) and hunting licenses (74.1 mill €/y) attract the lion's share of forest investments, amounting to around 652.1 mill. Euros per year, whereas aggregated investments in non-market ecosystem services like habitat provision (43.44 mill €/y) and carbon sequestration (2.53 mill €/y) remain an order of magnitude smaller. Third, most instruments target services for which forests show increasing capacity, while some services in poor condition or declining supply, are underprioritized or undermined through investments in competing services. Moreover, our results suggest that the current use of economic instruments primarily aligns with the sustainability pathways of <em>green economy/green growth</em> or <em>nature protection</em>.

Then, a comparative statics analysis of key parameters of dead organic matter and the harvested wood product carbon pool is conducted. The results show that the effect of the carbon pool parameters of dead organic matter and harvested wood products' on the optimal rotation usually depends on the economic environment, such as the discount rate and the time of their changes. Results of our case study indicate that considering the carbon sequestration in multiple carbon pools increases land expectation value and forest land carbon stocks. Meanwhile, different harvest wood products types and decay modes affect the optimal rotation differently. Our results demonstrate that different carbon accounting methodologies should be established for different types of harvested wood products, such as exponential decay for paper and paperboard and chi-square decay for solid wood products.

However, their plantations' productivity lag behind private and government estates. Moreover, these farmers often resort to unsustainable practices. Replanting presents a viable solution to enhance sustainability by bolstering yields and mitigating harmful practices. The Indonesian government, through the Palm Oil Fund Management Agency (BPDPKS), offers subsidies to incentivize farmers to implement replanting. However, replanting program uptake remains low. This study aims to investigate factors underlying the smallholders' propensity to engage in replanting by examining (1) their intention (stated preference) to replant their oil palm plantation with the financing scheme from BPDPKS, and (2) their actual replanting implementation (revealed preference). Combining survey data with in-depth interviews, the research identifies three key factors influencing their decision: a lack of funds and financing access, difficulties in obtaining land ownership certificate and business registration certificates, and challenges to implement good agricultural practices. Encouraging smallholders to participate in the replanting program is crucial for curbing further land expansion, as this expansion poses a significant risk of encroaching on forests and protected areas. Findings from the analysis of both intention and actual implementation provide valuable insights into smallholders' perspectives on replanting, underlining the need for comprehensive policy development and implementation.

In the European Union (EU) 550 million m<sup>3</sup> of wood is harvested annually, and is to a large extent processed by the wood industry. Little is known about the interplay between industrial capacity and the regional availability of timber resources. We compared the capacities from the European Forest Industry Facilities Database (EUFID) with the estimated wood supply from the procurement areas around processing industries, calculated using a spatially explicit resource model (EFISCEN-Space). We found that the estimated total capacity for the available European countries is 427 M m<sup>3</sup> roundwood equivalent (rw. Eq.) for pulp and paper (including both virgin and recycled fibres), 102 M m<sup>3</sup> for bioenergy (only bioenergy plants), and 153 M m<sup>3</sup> for sawmills. We then conducted an in-depth analysis of three case studies: Norway, the Czech Republic, and Germany. Given the current probability of trees being harvested (excluding disturbances) and the hypothetical optimal grading of the logs, the volume for each assortment type is closely aligned with the current capacity of each industry branch, indicating no overcapacity. We found undersupply of softwood of 3.4 M m<sup>3</sup> for the Czech Republic, 1.5 M m<sup>3</sup> for Norway, and 3.8 M m<sup>3</sup> for Germany. At the same time, in Germany, we found an oversupply of hardwood of 3.0 M m<sup>3</sup>. Additionally, a substantial amount of biomass graded as bioenergy was found for Germany and the Czech Republic, potentially serving as fuelwood in households. Concerning wood procurement areas, we concluded that a fixed radius of 100 km from the facility limited the availability of raw material procurement, particularly for bioenergy and pulp and paper mills, suggesting that these two product chains use a broader procurement basin than sawlogs.
