“…These results confirm that B. aegyptiaca is a characteristic species of dry areas of tropical Africa and tolerates low precipitation (<1000 mm) but high temperature (≈ 40 C). This corroborates the previous findings that mentioned moisture index arid of the quarter (Mwakapeje et al, 2019) and rainfall driest month (Avaligbé et al, 2021;Hounkpèvi et al, 2016) as the most important ecological factors for some plants distribution. In addition, the soil parameter introduced in the model had a positive impact on the prediction of the habitats for B. aegyptiaca.…”

Effectiveness of Balanites aegyptiaca conservation and sustainable exploitation requires a better knowledge of the intrinsic environmental factors linked with its current and future geographic distribution. This study aimed to map suitable areas for the conservation and domestication of B. aegyptiaca under present‐day and future climate conditions in Benin. A total of 424 occurrence records of B. aegyptiaca were combined with the environmental variables of two climatic scenarios (optimistic RCP 4.5 and pessimistic RCP 8.5) following the biodiversity modeling approach (biomod2). Findings were that under current and future climate conditions (RCP 4.5 and 8.5), almost one‐third of the country's area (protected and non‐protected areas), mainly located in the semiarid zone, presents a high probability of suitable areas for the conservation and domestication of B. aegyptiaca by 2055 time horizon. Exceptionally, a fine portion of medium suitable area for its distribution was found in the coastal area. Whatever the future climatic scenarios, a probable potential extension of the suitable areas (2.52% for RCP 4.5 and 0.43% for RCP 8.5) will be noted, thus emphasizing a positive impact of climate changes on the species. These findings are timely and could be used for setting appropriate management policies targeting the species in Benin.

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?
