“…The results on G. kola stem cuttings from young plants reveal that it is possible to regenerate entire plant of this species from organs other than the seeds, opening up the possibility of developing superior cultivars for cultivation by African farmers (Leakey 2014b). Stem cuttings of G. kola exhibited a good capacity to produce new shoots and roots, especially in non-mist polypropagators, although a greater number of roots would be beneficial.…”

(2016). Propagation of Garcinia kola (Heckel) by stem and root cuttings. Silva Fennica vol. 50 no. 4 article id 1588. 17 p. http://dx.doi.org/10.14214/sf.1588. Highlights• Roots and branches cuttings from mature forest trees are difficult to sprout.• The highest mean numbers of roots and buds produced were obtained with softwood cuttings.• The aqueous IBA treatment was more effective than the powder in promoting rooting and root development.• Non-mist poly-propagator gave the best propagation results.• Seedling stockplants cut above node 1 promoted most vigorous shoots production. AbstractThe availability of appropriate propagation techniques is a major constraint to the domestication of the forest trees widely used by rural communities; such as Garcinia kola (Heckel). This study tested the ability of root and stem cuttings to regenerate vegetatively when treated with indole-3-butyric acid (IBA), and set in non-mist poly-propagator within a shaded nursery. It found that G. kola is amenable to propagation by softwood stem cuttings. Attention was given to the effect of cutting age (softwood, semi hardwood) and IBA application with regard to the sprouting and rooting efficiency. Bud and leaf emergence time were also investigated, as was the coppicing ability of the stump. Results revealed that roots and branches from mature forest trees did not sprout under any culture conditions. The highest percentages of rooting (70-85%) were obtained with softwood cuttings set in non-mist poly-propagator, regardless of hormonal treatment. The mean numbers of buds (2.9 ± 0.4) and roots (2.6 ± 0.1) produced by softwood cuttings was significantly greater than those obtained in the Control. The best average emergence time of buds (25.1 days ± 9.3) and leaves (36.8days ± 8.4) was obtained with cuttings treated with IBA and set in non-mist poly-propagator against, 54.4 ± 12.5 and 72.6 ± 3.4 days respectively for the Control. In general, non-mist poly-propagator gave the best propagation results. When coppiced, the shoots emerging from stumps with one node were the most vigorous.

“…The idea to develop techniques and strategies for domesticating traditionally important and nutritious tropical trees emerged in the 1980s [21][22][23] based on a strategy to make wise use of genetic resources [24]. Since then, significant progress has been made [25][26][27] with a focus on community-based, participatory tree domestication in Cameroon driven by the farmers themselves [28][29][30][31]. This uses simple, low-technology vegetative propagation protocols [25,32] appropriate for remote locations with poor infrastructure and community-based Rural Resource Centres to provide capacity building and community coordination [33,34].…”

“…Over the last decade, a more hightech approach with key species has also evolved to increase the genetic knowledge and understanding fundamental to the future long-term development of these new crops [43]. However, in the short term, participatory domestication of socially-modified crops within farmer-friendly, wildlife-friendly, and climate-friendly agroforestry systems can clearly make a beneficial quantum leap for the planet and African people [31]. This results from rebooting agricultural production in ways that positively enhance its interactions with the environment and the local populations, thereby avoiding the trade-offs arising from conventional approaches to agricultural intensification [38].…”

International agricultural policies to address hunger and malnutrition in the tropics and sub-tropics have typically been based on approaches to the intensification of farming systems effective in industrialised economies where the social, economic, and environmental conditions and the infrastructure are very different to those in Africa. The consequence of this short-sightedness has been that agricultural productivity, dependent on ecosystem services from natural capital, has declined in Africa due to ecological and environmental collapse. This has undermined the livelihoods of the millions of smallholder farmers living on the brink of the cash economy, leading to severe social injustice. This review summarises advances in smallholder agriculture’s sustainable intensification in the tropics and sub-tropics, leveraging the domestication and commercialisation of wild indigenous tree species that produce nutritious, marketable, and useful food and non-food products. These are grown within diversified and multifunctional farming systems together with conventional food staples and local orphan crops to reduce land degradation, pollution, water extraction, and nutrient mining while promoting services such as pollination and other ecological functions. The benefits arising from this approach simultaneously address hunger, malnutrition, poverty, social injustice, and a stagnant economy, as well as important global issues such as climate change, loss of biodiversity and environmental degradation. Addressing these issues may also reduce the risk of future pandemics of zoonotic diseases, such as COVID-19. This set of serious global issues epitomise our divided and dysfunctional world and calls out for action. Enhancing sustainable smallholder productivity using indigenous and wild foods is an important international policy and business intervention, vital for achieving the 2030 Sustainable Development Goals and the rebalancing of the global economy by restoring natural capital within new African indigenous food industries.

“…AF supplies food for Jemowo with a mean of 3.66. Leakey (2014) stated that AF can be used as food resource both for household and commercial usage and this system can help to generate income like the case in Krinjing with a mean of 3.56 (Figure 5). This finding is also similar to Bado et al (2021).…”

Abstract. Rozaki Z, Rahmawati N, Wijaya O, Mubarok AF, Senge M, Kamarudin MF. 2021. A case study of agroforestry practices and challenges in Mt. Merapi risk and hazard-prone area of Indonesia. Biodiversitas 22: 2511-2518. This paper presents a case study of agroforestry (AF) practices and challenges in Mt. Merapi risk and hazard-prone area of Indonesia. AF has been practiced by farmers in Mt. Merapi risk and hazard-prone area from older generation. Each area in Mt. Merapi has different types of AF such as agrisilviculture, silvopasture, and agrosilvopasture. In the village of Glagaharjo, Yogyakarta, this system has been used for land restoration or conservation. 139 AF adopters were chosen from 269 respondents that have been randomly interviewed from four different areas around Mt. Merapi. Statistical descriptive method using values of mean and percentage were used. Additionally, multinomial Logistic regression was utilized to understand the model. The findings of the study show that the trend of AF is increasing, especially in Glagaharjo, after the 2010 eruption. AF systems are also found to be practiced for mitigation strategies in facing Mt. Merapi hazards and risk, especially for crop protection, and land and water conservation. Promoting AF as one of the coping strategies in facing Mt. Merapi hazards and risk is important as indicated by the results of this study.
