This study underscores the abundant biomass resources in the Gambella region, primarily composed of savanna and woody savanna, which encompass 77 % of the land area, consisting mainly of forest and agricultural waste. Leveraging these resources can ensure a renewable and sustainable cooking energy supply, aligning with Sustainable Development Goals (SDGs) related to clean energy and environmental conservation. Consequently, this thesis endeavors to identify optimal sites for establishing solar-powered non-wooden biomass briquetting plants across the region. Various spatial and non-spatial datasets, including solar radiation, slope, land use/land cover (LULC), and proximity to roads, rivers, and towns, were utilized for area delineation and mapping. Parameters such as solar radiation, slope, and river streams were derived from 30 m resolution digital elevation models (DEMs). The Analytical Hierarchy Process (AHP) was employed to calculate criteria weights for overlay analysis, resulting in a suitable solar farm site map. The study reveals that land use/land cover exerts the most significant influence, with a weight of 46.58 %, followed by solar radiation strength (20.42 %), slope (15.52 %), proximity to roads (8.26 %), proximity to rivers (5.46 %), and proximity to towns (3.77 %). By integrating parameter suitability and weight assignment in ArcGIS spatial analysis, a suitability map was generated, highlighting highly suitable areas predominantly along the North-South axis through central Gambella. This area covers approximately 12,094.49 km², constituting 47 % of the study area. These findings have practical implications, as they can inform local policymakers and actors in strategically addressing the region's dire need for sustainable cooking energy. This contribution can support the development of localized renewable energy strategies and promote long-term energy security in line with local energy policies.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"19 ","pages":"Article 100732"},"PeriodicalIF":2.7,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142706167","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}

We illustrate this via a case study: the Basque Country in Spain. Drawing on 33 qualitative in-depth semistructured interviews conducted in 2022 and 2023 with a wide variety of forestry actors, we aim to a) identify who the potential actors are that can trigger a change toward sustainable forest management, b) explore actors’ interactions and knowledge interchange that can foster a transformation toward sustainable forest management, and c) understand the opportunities and barriers that the main actors face to achieve sustainable forest plantation management. Our results show that a) those who may have the ability to induce a change in the forestry sector of the Basque Country are landowners, rangers and private sector companies; b) mutual learning happens in the day-to-day practices of forest plantation management while academic knowledge does not reach policy and practice; and c) barriers are related to managerial, political and individual dimensions that impair the way towards “close to nature” management and a “circular bioeconomy”, such as a perceived lack of supporting policies and knowledge, as well as increasing land abandonment. Opportunities to pose a potential way forward are, among others, forest plantations of native species providing high-quality timber, and opening access to additional markets, such as the ones funding the diversity of contributions that forest plantations may bring to people.

Here, we combine tree-ring data with biometric equation modeling to analyze how annual biomass increment varies according to tree age, species, latitude, and germination year. We generated 26,225 estimates of annual biomass increments for 136 individual trees, representing two evergreen gymnosperm conifer species (<em>Picea abies</em> (L.)

Annual biomass increments varied considerably between species, years and among individual trees within stands. On average, biomass increment remained positive throughout the lifespan across trees, species, and latitudes. Age-specific biomass increment was higher in the deciduous than in the evergreen species and declined with increasing latitude within species. For spruce and beech, biomass increment increased significantly with germination year, possibly reflecting faster growth in recent times in response to a warmer climate.

This Commentary paper identifies recent forest therapy offers and research in Asia and Europe that focus on the therapeutic effects of forests and examine their underlying rationales, practices, and status.

Based on a scoping review on forest therapy offers and research, we found that countries such as Japan and South Korea are ahead of European countries in the professionalization of forest therapy offers and respective studies. While the number of studies that demonstrate the positive health benefits of forests are increasing, there is a lack of understanding the link with forest management approaches and forest and health policies.

To assess the short-term effects of prescribed fires on soil fungal communities, we collected soil samples from both burned and unburned plots 12 months post-burning to perform genomic DNA analyses. Our findings indicate that prescribed burning does not significantly alter fungal diversity or composition, with only litter saprotrophs showing significantly higher levels of abundance in burned areas than in unburned areas. Valuable edible fungi persisted post-burning, suggesting that prescribed burning could be used to reduce wildfire fuel loads while preserving fungal biodiversity and valuable edible fungi.

They include: (1) distribution through the provincial revenue and expenditure budget (APBD), (2) distribution through intermediary institutions (LEMTARA), and (3) direct distribution or transfer to beneficiaries. Each mechanism is evaluated on effectiveness, efficiency, and equity, considering bureaucratic processes and stakeholder capacities. The study utilizes public deliberation by involving relevant stakeholders at the national and Jambi province levels and expert judgment by purposively selecting based on certain criteria to help determine the optimal mechanism as the reference for achieving Indonesia's climate mitigation goals and the administrative intricacies involved. The findings suggest that direct distribution to beneficiaries is the most efficient and equitable, although using LEMTARA is deemed slightly more effective for targeted fund allocation. The study provides recommendations for policy makers on enhancing institutional capacities and integrating flexible inclusive mechanisms to optimize JREDD+ benefit distribution at the sub-national level.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"18 ","pages":"Article 100726"},"PeriodicalIF":2.7,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142652226","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}
