DocumentPropagation and growth from seeds and root segment cuttings of fruit tree-plus Diospyros mespiliformis (Ebenaceae) in Benin West Africa
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The aim of the present experiment was to assess effectiveness of selected propagation methods, early nursery and field performance of D. mespiliformis (Ebenaceae). For instance, effects of seed pretreatment/root segment cuttings diameter, provenance and soil types on germination and growth vigor of the species was investigated using 144 seeds/root segment; laid in 500 g of three different soil types and soaked/planted in polyethylene bags replicated four times in three treatments and laid in 4×3×3 factorial Completely Randomized Design. Emergence of radicle (days), Seedlings/Shoot Height (cm), number of leaves, and Percentage survival were recorded two weekly for a period of 7 months. Time to event seed germination/shooting data analysis, ANOVA two ways and Generalized Mixed effects Model were used to assess effects of origin, pre treatment/diameter and soil types on germination, shooting and growth of Diospyros mespiliformis. Results indicated that propagation of the species can best be done through seeds and root cuttings. The essay revealed that seeds from woodland, savannah and parkland, sowed in compost and clay and pre treated (boiled water, tegument removed) had the highest germination percentage (69.9-86.67 %), while seeds in the control (no treatment, Inundated Forest and sandy) had very low germination of 17-35 %. No seed treatment showed deficiency in the survival and germination of the seeds of Diospyros mespiliformis, while borehole water aided the survival and bring back early (rapid) germination. Regarding RSC, leafy shoots formed percentage varied from 0 % in river sand to 64.6% in clay and compost substrate after 12 weeks. Results reveal also that among the three classes of diameter, shooting height decreases from clay to sandy while the same variable move in inverse order regarding RSC origin.

ArticleThe development prospect of coppiced dalbergia plantation in Indonesia
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Dalbergia latifolia Roxb. is a premium wood traded in the international market as Rosewood, and currently included in the CITES Appendix II. In Indonesia, D. latifolia is suitable and popular to be intercropped within agroforestry system. However, the species is generally considered as too slow-growing to be preferred to timber plantation trees. Thus, promoting private, community and government plantations is necessary to support future timber stock and gene conservation. This study was aimed to examine the possibility of establishing coppiced D. latifolia plantation. This study involved observation and measurement in the field and nursery. Field observation and measurement were carried out both in a private and national forested land in West, Central and East Java of Indonesia, while propagation trials were conducted at a nursery in Bogor–West Java. Field observation indicated that certain population from West Java showed faster growth that in the 3-4-year- the trees reached 15-27 cm in DBH. Vegetative propagation trials showed that root cutting is more prospective that that of shoot cutting (sprouting ability >90%). Experiment on root growth from planting stocks originated from root cutting produced massive lateral roots (total root length 4 m - 8 m within six month). Small roots with 4 m – 5 m in length can be source for producing new individuals. Field observation also revealed that the stumps produced 3 - >20 sprouts that can further utilize as shoot cutting sources and among them (1-3 sprouts) would develop into new individual and take the role as new main stem replacing the previous harvested one. Thus, it is prospective to develop a coppiced plantation of D. latifolia which will be beneficial in term of ecology and economy. The slow-growing tree term previously accepted in general term may not be applied as at suitable habitat they may grow aggressively and categorize as fast growing with the diameter increment can achieve 4–7 cm/year.

Book (stand-alone)Forest business incubation
Towards sustainable forest and farm producer organisation (FFPO) businesses that ensure climate resilient landscapes
2018Also available in:
No results found.Forest business incubation is a support process that accelerates the successful development of sustainable businesses in forest landscapes. There is much to develop. The aggregate gross annual value from smallholder producers within forest landscapes may be as much as US$1.3 trillion. Forest business incubation should be a key mechanism to implement the Paris Agreement on climate and the Sustainable Development Goals (SDGs). It can strengthen economic inclusion of forest and farm producer organisation (FFPO) businesses, increase rural incomes to reduce poverty, diversify those incomes to improve climate resilience, and incentivise forest restoration and sustainable management to mitigate climate change. It can also help improve product availability for established businesses and customers, pool lower-risk investment opportunities for financiers, and help inform policymakers on how best to deliver a win-win-win for the economy, society and the environment. It is that important! Business incubation practice generally has expanded rapidly in recent years. Since the first recorded business incubator was founded in 1959, establishment has risen sharply to more than 7,000 today – primarily in urban centres. They are variably financed through client fees, other business income, public and private grants, and loans. Over time the concept has evolved from primarily one of shared space (first generation) to shared space and mentoring (second generation) to shared space, mentoring and networking (third generation). Business incubators respond to needs that especially occur in newer business such as the lack of premises, facilities, market information, technological knowledge, business-management experience, procedures, finance and legitimacy. Remote forest landscapes present challenges for business incubation. Beyond exacerbating basic business support needs, such landscapes offer low densities of educated entrepreneurs, high logistical costs, scarce infrastructure to differentiate products, and few capable business mentors. These challenges may explain the limited penetration of business incubation thinking into forest landscapes. Forest landscapes also require a different type of service delivery model, because shared space is not often practical, requiring much more attention to on-site client visits, virtual services and field exchanges. The content of this book seeks to show how such challenges can be overcome. Chapter 1 begins by defining and introducing ‘business incubation’ and explaining why forest business incubation might be so important. It also specifies why forest business incubation is so challengingly different from models of urban business incubation. In the subsequent Chapters 2–12, detailed case studies are presented of attempts to deliver business incubation services in forest landscapes. Each case study introduces the incubator and its context, describes its institutional design, details the services it offers, outlines how the incubator-client engagement process is managed, comments on how impact is measured, and concludes with some thoughts and tips on best practice.
