Traditional homegardens (HGs) are considered to harbor high levels of plant diversity and have been therefore characterized as sustainable agro-ecosystems suitable for on-farm (incl. circa situm) conservation of plant genetic resources. While the functional structure of traditional HGs is poorly understood specifically for semi-arid and arid regions, their(More)
Wild edible fruits hold great potential for improving human diets, especially in agricultural societies of the developing world. In Africa, a well-known supplier of such fruits is the baobab (Adansonia digitata L., Malvaceae), one of the most remarkable trees of the world. Several studies in different African countries have highlighted this indigenous fruit(More)
Exotische Früchte aus fernen Ländern erlangen in Deutschland und Europa immer mehr an Bedeutung. Gerade in den Tropen und Subtropen ist die Vielfalt an Fruchtarten enorm groß. Das getrocknete Fruchtfleisch des Baobabs (Adansonia digitata L.) ist seit 2008 als neuartige Lebensmittelzutat für die Europäische Union zugelassen und mehr und mehr Produkte kommen(More)
The isolated Sudanese baobab (Adansonia digitata L.) populations, located at the northernmost limit of the East African distributional range of the species, are regarded as important genetic resources. The morphological variation in fruits of selected baobab trees in Kordofan, Sudan, was evaluated by sampling fruits and assessing their characteristics.(More)
The role of urban agriculture (UA) for the supply of fresh vegetables, fruits and meat for local markets is well known. The periodically flooded Gerif soils on the River Nile banks in the core of Khartoum city harbour vegetable gardens that supply perishable leafy vegetables with a short life cycle. In an effort to assess their sustainability and possible(More)
Iterative domestication processes by humans such as selection, translocation and cultivation are known to affect the morphological and genetic diversity of tree species. Since many of these species occur also in human-created homegardens (HG) this type of agroecosystem therefore represents an ideal setting to study such domestication processes. The(More)
Traditionally agricultural research has given little attention to underutilized or neglected crops. Grewia flavescens Juss., the donkey berry, is a fruit species which is found throughout semi-arid and sub-humid tropical Africa and sometimes cultivated in homegardens. The species is also known for its ornamental value and is used as a vegetable, fodder and(More)
The baobab (Adansonia digitata L.) is a remarkable key tree species with different uses in many African countries. International interest in the species has intensified in recent years. Despite the wide distribution of the baobab in many African regions, the tree has been reported to be absent in Uganda. In 2015 and 2016, research trips in the Central,(More)
Synsepalum dulcificum, an African native shrub, is a valuable species. All plant parts are of medicinal importance whereas the fruit known as magic berry, miracle berry, or sweet berry is consumed fresh. Surprisingly, very little is known on the species in terms of genotypes utilization and breeding. In this review we recalled the uses and importance of the(More)
Management intensification has raised concerns about the sustainability of homegardens in the Nuba Mountains, Sudan. This study aimed at assessing the sustainability of these agroecosystems following the approach of carbon (C) and nutrient balances. Three traditional (low input) and three intensified (high input) homegardens were selected for monitoring of(More)
