(Thymelaeaceae) is valued in many cultures because of its distinctive fragrance and its use in incense, perfumery, and traditional medicine. Large-scale harvesting from natural populations caused rapid depletion of the species in the wild, and the species is now listed as “Critically Endangered” and almost extinct in the wild. The promotion of this species in agroforestry systems may pave the way for its conservation. The present study aimed to quantify the growth and coppicing ability of agarwood under monoculture and polyculture stands. Monoculture stands aged more than 20 years, and stem girth (1.37 m above ground) of 60–70 cm had the highest growth increment of 3.73 cm yr−1. Monoculture stands (>10 years old) also recorded higher number of coppicing stocks than polyculture stands. The highest coppice growth increment (4.07 cm yr−1) was recorded in the 70–80 cm stem girth in monoculture stands. Based on the results, we recommend the promotion of agarwood trees with good coppice management in forestry programs to conserve the species while also meeting the economic needs of rural communities.","PeriodicalId":54313,"journal":{"name":"Journal of Sustainable Forestry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45145266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this area, however, this forest cover is declining due to natural causes associated with a change in the hydrosedimentological dynamics. Multitemporal assessment was performed to quantify the forest loss. Landsat images from the years 1986, 1998, 2003, 2013, and 2018 were downloaded and a supervised classification was performed using four cover classes: “Pterocarpus officinalis,” “other vegetation,” “waterbody,” and “bare land.” The results showed that the vegetation cover of Pterocarpus officinalis forest had an initial extent of 865.26 ha in 1986; for the 1986–1998 period, the reduction was 60.30 ha; for the 1998–2003 period, it was 399.15 ha; and for the 2003–2013 period, it was 78.30 ha. Contrary to previous periods, in the 2013–2018 period, 79.65 ha of forest was recovered. In conclusion, Pterocarpus officinalis forest lost approximately 50% of its cover during the 1986–2018 period. This information is of great importance for government and management entities for decision-making in the conservation and restoration of this forest.","PeriodicalId":54313,"journal":{"name":"Journal of Sustainable Forestry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41469595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent times, WEFs have been threatened by over-exploitation, land-use changes, and biodiversity loss. This study aims to (1) identify and document wild edible fruit plant species, (2) investigate the patterns of knowledge, use, and management of WEFs in the Ulu Masen protected area; and (3) assess threats to wild edible fruit plant species and recommend possible management scenarios for their conservation. The study was conducted in six villages of Pantai Ceuremen subdistrict, Southeast Aceh, Indonesia, namely Sikundo, Jambak, Canggai, Lawet, Pulo Tungoh, and Keutambang. The plant materials were randomly collected from the study area, while local knowledge was gathered through a semi-structured survey and in-depth interviews involving 209 respondents that were selected using random sampling. A total of 53 wild edible fruit plants from 30 genera and 21 families were found to be commonly used. Syzygium pycnanthum, Syzygium littorale, Syzygium polyanthum, Garcinia xanthochymus, Baccaurea polyneura, Flacourtia rukam, Sandoricum koetjape, and Baccaurea racemosa were the most important species for local communities in the study area. The WEFs in the study area is influenced by a variety of factors, primarily agricultural expansion, which means that conservation practices need to be improved through the implementation of management strategies, prioritizing species currently used by local communities. Management strategies based on traditional knowledge, such as community-based forest management systems (CBFMS) are being considered for future conservation, and they are also being implemented in other developing countries with similar circumstances.","PeriodicalId":54313,"journal":{"name":"Journal of Sustainable Forestry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41819126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alike several other technologies, the adoption status of agroforestry innovations in sub-Saharan Africa is considered poor. Studies have shown that plethora of biophysical and socioeconomic variables affect adoption of agroforestry innovations. In these studies, the contribution of psychological variables determining the voluntary decision-making on agroforestry adoption decisions is often neglected and marginally explored. This paper aims at exploring the role of psychological variables for the sustained agroforestry adoption intention. We employed the Theory of Planned Behavior (TPB) to predict sustained agroforestry adoption intentions of 327 farmers in the Amhara region of Ethiopia. Intention for sustained agroforestry woodlots adoption is assessed by employing the confirmatory factor analysis. Farmers’ intention to sustain adoption of agroforestry woodlot innovations is principally driven by their positive evaluation of the cash and livelihood benefits of the innovations (attitude) compared to traditional farming, their own capability to produce the innovations and accessibility of resources (perceived behavioral control), and the farmers’ perception of pressure and expectations from experts and important others (subjective norms). By employing TPB, this study brings a theoretical contribution to the TPB framework and measurement guidelines, unveils limitations of applying confirmatory factor analysis in a ‘new’ (woodlots) context and suggests data-based policy and development implications.","PeriodicalId":54313,"journal":{"name":"Journal of Sustainable Forestry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46875254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assessed species composition and carbon stock in two different agroforestry practices (traditional and improved) adopted in the mid-hills of Nepal. We found higher species richness and dominancy of Citrus synenssis (fruit species) in the improved practice, whereas we found higher species evenness, diversity, and dominance of Ficus clavata (fodder species) in the traditional practice. 0.35 of the similarity index between the two practices indicated that there was 65% difference in species number between the two practices. The improved practice had larger trees with higher frequency compared to traditional practice. The carbon inventory reflected that the total carbon stock between the two practices was insignificant, whereas the total biomass carbon was significantly higher in the improved practice than in the traditional practice. Therefore, improvement in traditional practices has the potential to increase biomass and sequester more carbon within the same unit of land. However, maintaining species diversity is a concern in the improved practice. We suggest policymakers and concerned stakeholders for prioritizing improved agroforestry practice and maintain species diversity while designing strategies for agroforestry promotion and climate change mitigation.","PeriodicalId":54313,"journal":{"name":"Journal of Sustainable Forestry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59595472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Local knowledge is key to help smallholder farmers to cope with climate change and variability to attain sustainable forest management. However, there is limited understanding of what shapes human adaptation to climate change in various sectors at local level including forestry in sub-Saharan Africa. Therefore, this study explored the awareness, knowledge and perception of forest-dependent communities on climate change and variability around Phirilongwe and Mchinji forest reserves in Malawi. Empirical data was collected using household surveys (n = 422), key informant interviews (16), and focus group discussions (8). Results suggest that 60% of respondents in Mchinji were aware of climate change as compared to only 35% in Mangochi. Results record that respondents perceived increased erratic rainfall, high temperatures and strong winds and changes in seasons. The main factors influencing their climate perception includes possession of farming skills (p = .002), Education (P = .04), gender (P = .002) and possession of livestock keeping skills (p = .02). However, the cube root stratification method indicates that their level of knowledge falls in the low-level category. Although negligible proportion of climate skepticisms was exposed, a strong belief in anthropogenic causes of climate change and willingness to adopt environmental friendly intervention measures were revealed. However, the presence of the believers in the cultural and spiritual causes of climate change in the study area presents a challenge to mobilize them toward implementation of climate intervention measures and forest management. We therefore recommend their participation in the climate adaptation intervention designs and multiple use of various strategies and methods that will help to address their livelihoods at the same time improve their climate information and knowledge.","PeriodicalId":54313,"journal":{"name":"Journal of Sustainable Forestry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44904316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
