Dioscoreophyllum cumminsii commonly known as Serendipity berry is one of the African indigenous fruits that has received poor attention from scientific research and funding even though it is a reservoir of many nutritional and medicinal potentials. In Nigeria, as well as in other African countries, Serendipity berry fruit is known as a tasty sweetening protein fruit. The berries contain a water-soluble and highly sweet protein called “Monellin” or “Serendip” which is one of the sweetest known naturally-occurring substances in fruits of plants. Monellin is up to 3,000 times sweeter than sucrose, with its precursor coming from protein and not carbohydrate as in sucrose. Monellin could be used as a substitute to sugar for diabetics, dieters and for a healthier life style. It has the potential of being utilised in the formulation of food and drugs to enhance the diets of other vulnerable groups. Dioscoreophyllum cumminsii is threatened and could go into extinction if appropriate actions for its propagation, production and conservation are not undertaken immediately. Currently, there is dearth of information on the consumption patterns, cultivation, management, advocacy for its valorisation and sustainable conservation of its genetic resources.

“…This equates to 5-7% of the world's trees flora, with five of its countries appearing as the botanically best explored on the continent. These trees produce a large number of Non-Timber Forest Products (NTFPs)-most of which are neglected, underutilized and poorly documented [6,[177][178][179][180][181][182][183][184][185][186][187][188][189][190]. According to Ingram [191], 951 and 706 species are exploited for NTFPs in the Democratic Republic of Congo and Cameroon, respectively, 35% of which are traded locally.…”

This paper follows the transition from ethnobotany to a deeper scientific understanding of the food and medicinal properties of African agroforestry tree products as inputs into the start of domestication activities. It progresses on to the integration of these indigenous trees as new crops within diversified farming systems for multiple social, economic and environmental benefits. From its advent in the 1990s, the domestication of indigenous food and non-food tree species has become a global programme with a strong African focus. This review of progress in the third decade is restricted to progress in Africa, where multi-disciplinary research on over 59 species has been reported in 759 research papers in 318 science publications by scientists from over 833 research teams in 70 countries around the world (532 in Africa). The review spans 23 research topics presenting the recent research literature for tree species of high priority across the continent, as well as that in each of the four main ecological regions: the humid zone of West and Central Africa; the Sahel and North Africa; the East African highlands and drylands; and the woody savannas of Southern Africa. The main areas of growth have been the nutritional/medicinal value of non-timber forest products; the evaluation of the state of natural resources and their importance to local people; and the characterization of useful traits. However, the testing of putative cultivars; the implementation of participatory principles; the protection of traditional knowledge and intellectual property rights; and the selection of elite trees and ideotypes remain under-researched. To the probable detriment of the upscaling and impact in tropical agriculture, there has been, at the international level, a move away from decentralized, community-based tree domestication towards a laboratory-based, centralized approach. However, the rapid uptake of research by university departments and national agricultural research centres in Africa indicates a recognition of the importance of the indigenous crops for both the livelihoods of rural communities and the revitalization and enhanced outputs from agriculture in Africa, especially in West Africa. Thus, on a continental scale, there has been an uptake of research with policy relevance for the integration of indigenous trees in agroecosystems and their importance for the attainment of the UN Sustainable Development Goals. To progress this in the fourth decade, there will need to be a dedicated Centre in Africa to test and develop cultivars of indigenous crops. Finally, this review underpins a holistic approach to mitigating climate change, as well as other big global issues such as hunger, poverty and loss of wildlife habitat by reaping the benefits, or ‘profits’, from investment in the five forms of Capital, described as ‘land maxing’. However, policy and decision makers are not yet recognizing the potential for holistic and transformational adoption of these new indigenous food crop opportunities for African agriculture. Is ‘political will’ the missing sixth capital for sustainable development?

The importance of Vitellaria paradoxa has necessitated its inclusion in the ongoing afforestation project which requires mass production of its seedlings. The shea-butter tree produces oil-rich seeds that are important to cosmetic and food and nutrition industries. It is a deciduous tree which could survive in the dry-savannah and help withstand desert encroachment. However, overexploitation of its timber for firewood and charcoal production made it vulnerable. In-vitro propagation of this species could be a viable means towards its mass propagation. Two plant-hormones: Gibberellic Acid (GA3) and Benzyl Amino Purine (BAP) were used to grow the plant in different combinations making up six treatments (A-F) with 6 replicates in each group. The combinations include 1.5/0, 1.5/1.0, 1.5/1.5, 2.0/0, 2.0/1.0, 2.0/1.5 mg/L of GA3/BAP, which were used to grow 2cm nodal cuttings of the V. paradoxa on half-strength Murashige and Skoog (MS) media. Treatment F (with 2.0/1.5 mg/L GA3/BAP) produced the highest number of leaves (2.4 ± 0.6, 3.2 ± 0.8) and longest shoot length (1.1 ± 0.3 cm, 1.4 ± 0.5 cm) at 4 and 8 Weeks After Inoculation (WAI), respectively. The results of this study showed that application of growth- enhancing hormones for the regeneration of important tree species could provide means for their mass propagation so as to meet the need for afforestation projects. Keywords: Vitellaria paradoxa, Afforestation, In-vitro propagation, Mass propagation.
