Abstract The province of Aceh at the northern tip of Sumatra has a total area of 5,75 million hectares. Its forest resources are considerably extensive as 60% of its total land area is still considered as ‘forest area’. Non-Timber Forest Products (NTFP) are defined as any wild plant and animal products harvested from forests, e.g., ‘jernang’ or dragon blood (Daemonorops spp.). It is classified as one of the valuable NTFP’s harvested from the forests in Aceh. Its morphological features resemble that of rattan (Calamus spp.), both of which belong to Aracaceae. The red resin of Daemonorops spp. is highly valued in Chinese medicine and possesses anti-inflammatory, anti-tumor, and anti-hemostatic properties. Almost 112 species of Daemonorops spp. exist. However, only 10% produces the red resin. Daemonorops draco, D. mattanensis, D. didymophylla are considered to have significant economic values. Over the past decade, a farmer living in central and western Aceh has cultivated dragon blood plants in small farms and sold the seedlings. In this study, the morphological variations of dragon blood (N=11) from Kuta Panang in central Aceh were assessed, and the Principal Component Analyses (PCA) were applied in order to distinguish the three species. Up to 92% of total variations were significantly explained with PC1, while the remaining were explained with PC2. Among the three species measured with PCA, Daemonorops draco or known as super ‘jernang’, appeared to have more distinctive morphological characteristics, e.g., fruit-, and stem diameter, as well as a number of fruit per trunk. These characteristics would contribute to better yield and field performance.

The City

This article aims to identify and assess the socio-economic and environmental implications of supplying charcoal in the city of Yaounde. To achieve the above-mentioned goal, investigations based on a standardized questionnaire (130 charcoal producers and sellers), formal interviews (7 resource persons), informal discussions, field observations and floristic survey were carried out in Bikok between the last quarter of 2016 and the second quarter of 2017. Bikok, a subdivision located in the neighbourhood of Yaounde is one of the most important supply sites of charcoal for the city. Investigations revealed that, accelerated demographic growth over the past fifty years, unemployment and poverty constitute the main factors for the increase in the production and consumption of charcoal in the city. Poverty, unemployment and the urge for the satisfaction of basic needs constituted the main reasons for involvement of 98.8% of charcoal producers in the activity. The increase in urban demand for charcoal is at the origin of several significant biophysical impacts, including the degradation of forests and soils as well as the decrease in the availability of some Non-Timber Forest Products and animal species. In the survey villages, a total area of 3.1 hectares of forest is cut each year and the average distances from inhabited areas to harvesting areas, increased from 0.8 to 5 km in 10 years. 76.6% of charcoal producers believe that some animal species are increasingly rare in the locality. On the socio-economic level, this activity creates jobs, generates income thereby increasing the living standards of producers and sellers. More than 300 people are involved in this activity who earns on average an income of 3000 to 6000 Central African Franc (XAF) per day. Decrease in the availability of certain NTFPs and damage to the health of producers constituted some of the negative socio-economic impacts of this activity. It is imperative to adopt measures to limit the negative impacts of this activity while ensuring a sustainable supply of charcoal in the city or the use of alternative sources of fuel.

Support Mechanisms

The gathering and commercialisation of non-timber forest products (NTFP) in Europe has repeatedly been praised for its potential to support rural development. However, political support mechanisms explicitly targeting NTFP remain underdeveloped. In this study, we aimed to contribute to the design of support mechanisms by understanding the factors that influence the commercialisation of wild plants by organic farmers. We first developed a conceptual framework based on fifteen factors and then applied the framework to a case study in South Tyrol (Alto Adige), Italy. Semi-structured interviews were conducted with all fourteen members of the Vereinigung Südtiroler Kräuteranbauer (Associazione Coltivatori Sudtirolesi Piante Officinali), who commercialised wild plant species, and the data were then analysed using qualitative content analysis. Agricultural intensification, pesticide drift, limited access to gathering sites suitable for organic certification, legal restrictions, lack of consumer awareness about the additional value of organic wild plant certification, and limited product diversity were perceived as limiting factors; management techniques in organic farming, organic certification, a trend for wild, regional and healthy foods, the availability of training, and favourable cultural values and attitudes towards wild plant gathering were perceived as supportive. This study offers a comprehensive understanding of the many diverse factors that may influence wild plant commercialisation in Europe and beyond and provides guidance on how political support mechanisms could unlock the much heralded potential of wild plant commercialisation for rural development.

<p><strong>Abstract</strong><br />Nowadays, more and more people are turning to modern and contemporary style when it comes to choosing furniture for their homes, offices, restaurants, or hotels. In the past we might tend to back the use of natural elements, and one of the many popular products are bamboo. Bamboo as one of the most important non-timber forest products and fastest-growing plants in the world. As it known that bamboo craft is a folk craft products that has been around for a long time and developed hereditary, therefore we should preserve it. At first the user<br />of bamboo furniture is from the family environment which later evolved to reach a wider market. Many craftsmen developed an appreciation of the existing ones to create a new design that is estimated to sell in the market. The hope is to make<br />our bamboo furniture craft products can compete with the products of other countries.</p><p><br /><strong>Abstrak</strong><br />Saat ini semakin banyak orang yang beralih ke gaya modern dan kontemporer dalam memilih mebel untuk rumah tinggal mereka, kantor, restoran, atau bahkan hotel. Dahulu mungkin kita cenderung untuk memilih desain dan gaya klasik, tetapi sekarang ini orang cenderung kembali mempergunakan unsur-unsur alam, dan salah satu produk alam yang banyak digemari adalah bambu. Bambu sebagai salah satu produk non-kayu yang penting serta tanaman yang pertumbuhannya paling cepat di dunia. Seperti diketahui bahwa kerajinan bambu merupakan produk kerajinan rakyat yang telah ada sejak lama dan dikembangkan secara turun temurun, maka sudah<br />selayaknya hal ini perlu dilestarikan. Pada mulanya pemakai kerajinan mebel bambu hanyalah dari lingkungan keluarga yang kemudian berkembang hingga mencapai lingkungan pasar yang lebih luas. Banyak para pengrajin mengembangkan apresiasi yang sudah ada dengan membuat desain baru yang diperkirakan akan laku di pasaran.

Pyrus hopeiensis is a valuable but endangered wild resource in the genus Pyrus. It has been listed as one of the 120 wild species with tiny population in China. The specie has been little studied. A preliminary study of propagation modes in P. hopeiensis was performed through seed propagation, hybridization, self-crossing trials, bud grafting, branch grafting, and investigations of natural growth. The results showed that the population size of P. hopeiensis was very small, the distribution range was limited, and the habitat was extremely degraded. In the wild population, natural hybridization and root tiller production were the major modes of propagation. Whole genome re-sequencing of the 23 wild and cultivated accessions from Pyrus species collected was performed using an Illumina HiSeq sequencing platform. The sequencing depth range was 26.56x−44.85x and the average sequencing depth was 32x. Phylogenetic tree and principal component analyses (PCA) based on SNPs showed that the wild Pyrus species, such as PWH06, PWH07, PWH09, PWH10, PWH13, and PWH17, were closely related to both P. hopeiensis HB-1 and P. hopeiensis HB-2. Using these results in combination with morphological characteristics, it speculated that P. hopeiensis populations may form a natural hybrid group with frequent gene exchanges between and within groups. A selective elimination analysis on the P. hopeiensis population were performed using Fst and π radio and a total of 381 overlapping genes including SAUR72, IAA20, HSFA2, and RKP genes were obtained. These genes were analyzed by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) function enrichment. And four KEGG pathways, including lysine degradation, sphingolipid metabolism, other glycan degradation, and betaine biosynthesis were significantly enriched in the P. hopeiensis population. Our study provided information on genetic variation, evolutionary relationships, and gene enrichment in P. hopeiensis population. These data will help reveal the evolutionary history and origin of P. hopeiensis and provide guidelines for subsequent research on the locations of functional genes.

Abstract The genus Pinus is classified as one of the most widely distributed genera of conifer trees, that are majorly distributed in the Northern and Southern hemispheres. Pinus merkusii is the only member of the genus Pinus that is adapted in the tropics and grows naturally in south Equator. Its natural distribution found through-out Southeast Asia, e.g. in Indonesia; particularly on Sumatran Island. Three native strains are known on Sumatra: Aceh, Kerinci, and Tapanuli; with the first one is known as the largest population among the three and grows naturally on the high altitudes. The wood has been utilized in building construction, while the resin collected is classified as one of the most valuable Non Timber Forest Products (NTFP) worth up to US $ 50 million/year and applied in many industries. Planting of citron grass (Cymbopogon sp.) has been ’booming’ over the past seven years in the middle regions of Aceh due to its attractive selling price. As consequences, many Pinus trees have been logged and demanded as fire woods in the distillation process of citron grass. Thus, the citron grass’ plantation has been directly threatening the existence of Pinus forests. Therefore, in-situ conservation effort should be started from now on. Here, we would like to report the morphological variation (N= 15 traits) of natural Pinus (e.g., plant height, diameter of main stem, number of crowns per branch, etc.). The morphological data collected were then analysed with the Principal Component Analyses (PCA), in order to cluster the major agronomical parameters among them. This morphological data would be complemented and benefitted the efforts in the genetic study of Aceh Pinus.

Abstract. Sungkawati M, Hidayati L, Daryono BS, Purnomo. 2019. Phenetic analysis of Curcuma spp. in Yogyakarta, Indonesia based on morphological and anatomical characters. Biodiversitas 20: 2340-2347. Curcuma spp., also known as ginger (Zingiberaceae), has economic value in traditional medicine. However, its many morphological variations cause difficulties in identification and classification. Therefore, observation of its morphological and anatomical characteristics, and of the phenetic relationships between Curcuma species, is important. This research aims to determine the specific characteristics of Curcuma spp. and to examine its phenetic relationships based on morphological and anatomical characteristics. The research was conducted in July 2018-February 2019 in the Bantul, Gunungkidul, Sleman and Karanganyar regions. Observation of the anatomical characteristics was conducted on the leaves and rhizomes and the data analyzed according to descriptive and quantitative/numerical methods. Clustering analysis with the Gower General Similarity Coefficient and Principal Component Analysis (PCA) was performed to determine the role of each character in groupings. The results of the research found seven species from 23 OTUs observed (C. aeruginosa, C. domestica, C. manga and C. xanthorrhiza, each with four OTUs; C. soloensis and C. zedoaria, with three OTUs each; and C. heyneana with one OTU) and showed that specific morphological characteristics were found in the flesh color rhizome, pseudostem color and midrib color. Specific anatomical characteristics were evident in the secretion cell color and the presence of trichomes on the leaves and rhizomes. The dendrogram shows a 0.70 phenon line consisting of two groups, group A (C. soloensis and C. domestica) fused in a 0.760 similarity index, and group B (C. aeruginosa, C. mangga, C. heyneana, C. soloensis, C. xanthorrhiza and C. zedoaria) fused in a 0.654 similarity index, which means that C. soloensis and C. domestica have a close phenetic relationship. The 0.80 phenon line consisted of five groups: C. domestica, C. soloensis, C. xanthorrhiza, C. zedoaria-C. mangga-C. heyneana and C. aeruginosa.

Protected Areas (PAs) are created for the protection and maintenance of biological diversity, but many of Ghana’s PAs are subjectto severe pressures and threats, the main pressures being the illegal extraction of natural resources. Rattans are indisputablyone of the most important Non-Timber Forest Products (NTFPs) in Ghana’s Protected Areas that is without doubt one of thereasons for which it has drawn the attention of researchers. In this study the illegal rattan extraction patterns in the AnkasaConservation Area (ACA) in Ghana was inspected. Simple random sampling and Snowball sampling techniques were used. Datacollection employed the use of semi-structured questionnaires, interviews and field enumeration of rattans as well as an analysisof Effective Patrol Man-days (EPMDS) from 2004 to 2012. The results showed a significant positive correlation (r = 0.75, p<0.05, r2 = 0.557) between patrol effort and rattan extraction encounters. In addition, there was a general reduction in illegalrattan extraction encounters from 2004 to 2012 at a rate of 4.3 per year. The highest illegal rattan extraction incidences wererecorded in 2006 (76 encounters), 2005 (35 encounters), 2008 (22 encounters), 2004 (18 encounters) and the least incidencewere recorded in both 2010 (3 encounters) and 2011 (3 encounters).The research also revealed that Eremospatha macrocarpawas the most extracted rattan species followed by Laccosperma secundiflorum. The major rattan extraction and trade routesoriginate in the northern parts and in the area east of the reserve and also south of Draw River Forest Reserve. Generally, rattanpoaching in Ankasa Conservation Area has declined, but there are still human incursions in the northern part of the reserve. Thestudy recommended an intensification of patrols in the north of the reserve. Also, enrichment planting and Agroforestry practicesof inter-cropping rattans with seasonal crops should be pursued vigorously for the local communities.

This study sought to: (1) identify the types and sources of Non-Timber Forest Products (NTFPs) traded; (2) find the frequencyof the NTFPs trade and (3) identify the challenges in NTFPs trading in the Sunyani Municipality. The survey was carried outfrom February, 2014 to April, 2014 mainly at the Sunyani Central and Nana Bosoma Markets in the Sunyani Municipality. Thetarget population comprised NTFPs collectors (gatherers), sellers and consumers. Respondents were purposively sampled. Atotal of 100 respondents were engaged in this study. The NTFPs were grouped into six categories namely; food, medicine,building materials, packaging materials, artefacts and domestic utensils. Key informants’ interviews were also conducted atthe Sunyani Forest Services Division to triangulate the data already gathered. Statistical Package for Social Sciences was usedto analyze the data obtained. The study demonstrated that domestic utensils (37%), food (33%), medicinal products (12%),packaging materials (9%), artefacts (6%) and building materials (3%) were the types of NTFPs traded in the two market centers.The results also showed that majority of the respondents (77%) harvest their NTFPs from forest lands as against 23% whoharvest from communal lands. A significant proportion of the respondents (52%) traded in above 40 kg of NTFPs and only 4%were seen trading in 10 kg of NTFPs. The study further highlighted that food (28%) and domestic utensils (26%) were regularlybrought to the market centers on weekly basis whilst significant proportions of medicinal products (9%), building materials(3%) and artefacts (4%) were brought to the market venues on monthly basis. Cumbersome permit procedure (40%), increasedmarket demand (15%) and financial constraints (20%) were identified as some of the challenges encountered in NTFPs tradingin the Sunyani Municipality. To ensure strict monitoring and sustainability of the resource, there is the need for sensitizationprogramme on the importance of NTFPs in rural livelihood and why their conservation is vital in meeting the needs of thepresent generation whilst not undermining their potential in supplying the needs of future generations.
