  • Social challenges and opportunities in agroforestry: cocoa farmers’ perspectives 

    Bosselmann, A.S.; Boadi, S.A.; Olwig, M.F.; Asare, R. (Palmgrave Macmillan, 2024)
    Agroforestry practices in cocoa cultivation have historical roots going back to the Mayan sacred groves in Mesoamerica. Today, agroforestry cocoa, i.e., the integration of shade trees, plants and crops in cocoa systems, is promoted as a climate smart practice by public and private institutions. Shaded cocoa can sustain or even increase cocoa yields and the agroforestry systems may provide additional output for household consumption and sale as well as improve the microclimate and soil conditions ...
  • Host plant resistance to insects in pulse crops 

    Togola, A.; Ongom, P.O.; Mohammed, S.B.; Fatokun, C.; Tamo, M.; Boukar, O. (Springer, 2024)
    Pulses are important sources of protein, dietary fiber, vitamins, and minerals for human nutrition and are widely cultivated in many countries around the world. Crops belonging to pulse include mainly chickpeas, mung bean, lentils, pigeon peas, and cowpeas. Pulse production and storage are negatively affected by a variety of biotic and abiotic factors, such as insect pests, diseases, parasites, low soil fertility, heat, and drought. Among these, insect pests have the most significant impact on ...
  • Household economics of cocoa agroforestry: costs and benefits 

    Boadi, S.A.; Bosselmann, A.S.; Owusu, K.; Asare, R.; Olwig, M.F. (Palmgrave Macmillan, 2024)
    Current research suggests that cocoa agroforestry systems could offer stable yields, additional benefits and income from shade trees, despite potential added costs, such as from the purchase of insecticides. There is a paucity of profitability studies of different cocoa agroforestry systems. Only few of them go beyond a narrow focus on cocoa yields to model the entire agroforestry system and thus do not advance our understanding of the socio-economic value of other ecosystem goods. Based on survey ...

    Nair, R.M.; Pujar, M.; Cockel, C.; Scheldeman, X.; Vandelook, F.; van Zonneveld, M.; Takahashi, Y.; Tallury, S.; Oyatomi, O.; Giovannini, P. (Global Crop Diversity Trust, 2023)
  • Designing dioscorea genomes for improved nutritional and pharmaceutical properties 

    Bhattacharjee, R. (Springer, 2023-12-15)
    Dioscorea species, commonly known as “Yams,” belong to family Dioscoreaceae consisting of about 600 species distributed from Africa, Asia, the Caribbean’s South America, and the South Pacific islands. The tuber of this genus is well known for their organoleptic properties, making them the most widely used food for carbohydrate, dietary supplements, and famine food. West Africa represents the region where yams are mostly consumed because of their underground and/or aerial tubers representing valuable ...
  • Cocoa under heat and drought stress 

    Mensah, E.O.; Vaast, P.; Asare, R.; Amoatey, C.A.; Owusu, K.; Asitoakor, B.K.; Ræbild, A. (Springer, 2023)
    Cocoa (Theobroma cacao L.) is an important cash crop in many tropical countries, particularly in West Africa. Heat and drought are both known to affect the physiology of cocoa plants through reduced rates of photosynthesis and transpiration, as well as changed physiological processes such as the functions of photosystems, chlorophyll synthesis, stomatal conductance and expression of heat-shock proteins. This in turn leads to decreased yields and increased risks of mortality under severe heat and ...

  • Agricultural transformation in maize producing areas of Africa 

    Woomer, P.L.; Roobroeck, D.; Mulei, W. (IntechOpen, 2024-01)
    Maize is a critical staple cereal across Sub-Saharan Africa but attempts to improve its productivity in small-scale farming systems often prove disappointing. The 12 key technologies required to overcome poor yields are mostly known, but the manner that they are mobilized, packaged, and delivered requires re-evaluation. Combinations of better varieties and their necessary accompanying inputs must become more available and affordable for an African maize revolution to succeed, and land must be ...
  • Nematode problems in tuber crops and their sustainable management 

    Kolombia, Y.A.; Fabiyi, Y. (Elsevier, 2023)
    In many subtropical and tropical countries, the most significant food commodities produced are those that are grown from tubers and roots (R&T). The R&T include yams (Dioscorea spp. L.), cassava (Manihot esculenta Crantz), and sweet potato (Ipomoea batatas (L.) Lam.) and edible aroids such as Taro (Colocasia esculenta Schott.) and Tannia (Xanthosoma sagittifolium Schott.). These crops represent the second-largest global source of carbohydrates, after cereals, in the tropical world, with a projected ...

  • Technology promotion and scaling in support of commodity value chain development in Africa 

    Woomer, P.L.; Zozo, R.; Lewis, S.; Roobroeck, D. (IntechOpen, 2023-03-07)
    Strengthening the production and processing of key food commodities forms the basis of agricultural development in Africa. These value chains follow a quasi-linear progression across seven main segments: farm planning > land preparation and crop establishment > field production > harvest > post-harvest handling > marketing > and value addition. Each of these consists of sub-segments whose improvement depends upon promotion and adoption of specific modernizing technologies. The technologies either ...
