    • Adaptation strategies to climate change and impacts on household income and food security: evidence from Sahelian region of Niger 

      Zakari, S.; Ibro, G.; Moussa, B.; Abdoulaye, T. (2022-03-01)
      Sahelian countries, particularly Niger, are more vulnerable to climate change due to the high dependence of most of their populations on rain-fed agriculture and limited capacities to respond to climate variability and change. This paper examines the factors influencing climate change adaptation strategies and the impacts on household income and food security in rural Niger. For this purpose, we collected data from 1783 valid rural households in four main agricultural regions of Niger. The results ...

    • Strategizing research and development investments in climate change adaptation for root, tuber and banana crops in the African Great Lakes Region: a spatial prioritisation and targeting framework 

      Vandamme, E.; Manners, R.; Adewopo, J.; Thiele, G.; Friedmann, M.; Thornton, P. (2022-10-22)
      CONTEXT Given the significance of climate change impacts on farming communities, large investments are made by research and development actors, including farmers themselves, to adapt agricultural systems. A data-driven approach is required to guide these investments and maximize their impact. In the African Great Lakes Region (GLR), root, tuber and banana (RT&B) crops are a vital component of smallholder farming systems, but little is known about strategies to mitigate climate change impacts on ...

    • Taro in west Africa: status, challenges, and opportunities 

      Oladimeji, J.J.; Kumar, P.L.; Abe, A.; Vetukuri, R.R.; Bhattacharjee, R. (2022-09-01)
      Taro is an ancient nutritional and medicinal crop woven into the fabric of the socio-economic life of those living in the tropics and sub-tropics. However, West Africa (WA), which has been a major producer of the crop for several decades, is experiencing a significant decline in production as a result of taro leaf blight (TLB), a disease caused by Phytophthora colocasiae Raciborski. A lack of research on taro in WA means that available innovative technologies have not been fully utilized to provide ...

    • Population genomics of yams: evolution and domestication of Dioscorea species 

      Sugihara, Y.; Kudoh, A.; Oli, M.T.; Takagi, H.; Natsume, S.; Shimizu, M.; Abe, A.; Asiedu, R.; Asfaw, A.; Adebola, P.O.; Terauchi, R. (Springer, 2021)
      Yam is a collective name of tuber crops belonging to the genus Dioscorea. Yam is important not only as a staple food crop but also as an integral component of society and culture of the millions of people who depend on it. However, due to its regional importance, yam has long been regarded as an “orphan crop” lacking a due global attention. Although this perception is changing with recent advances in genomics technologies, domestication processes of most yam species are still ambiguous. This is ...

    • CRISPR-Cas9-based genome editing of banana 

      Tripathi, L.; Ntui, V.O.; Tripathi, J.N. (Springer, 2020)
      Genome editing is an emerging powerful new breeding tool, which can be applied for genetic improvement of banana for important agronomic traits such as resistance to biotic stresses, adaptation to climate change, and high yielding. Banana is an important staple food and cash crop, feeding millions of people in tropical and subtropical countries. Recently, CRISPR-Cas9-based genome editing system has been established for banana in a few laboratories. Here, we describe the procedures for generation ...

    • Abundance and diversity of tomato rhizosphere microbes and their effect on bacterial wilt disease 

      Nampamya, D. (Makerere University, 2019-12)
      The use of land for agricultural production is always accompanied with changes in microbial diversity and emergency of new pathogens. Microbial imbalances and unevenness have enhanced multiplication of pathogens and proliferation of many soil borne diseases, which are tedious to control. Biocontrols are promising and environmentally friendly agents against such diseases. However, microbiome composition and land use management have been mentioned as core factors in effectiveness of biocontrols. ...

    • The forest-based farming system: highly diverse, annual and perennial systems under threat 

      Hauser, S.; Norgrove, L.; Tollens, E.; Nolte, C.; Robiglio, V.; Gockowski, J. (Routledge, 2019)
      African forest-based farming systems (FBFS) are the starting point for most humid zone farming systems; they exist only at low population densities and, depending on population growth, are a relatively short transition phase into more sedentary systems with higher levels of specialization. FBFS provide a wide range of food and non-food products for many of which no alternative sources exist. FBFS farmers are highly food secure yet poorly connected to markets and service providers, thus severely ...

    • The tricot citizen science approach applied to on-farm variety evaluation: methodological progress and perspectives 

      van Etten, J.; Abidin, E.; Arnaud, D.; Brown, E.; Carey, E.; Laporte, M.-L.; López-Noriega, I.; Madriz, B.; Manners, R.; Ortiz-Crespo, B.; Quirós, C.; de Sousa, K.; Teeken, B.; Tufan, H.A.; Ulzen, J.; Valle-Soto, J. (International Potato Center, 2020-12)
      Tricot (triadic comparisons of technologies) is a citizen science approach for testing technology options in their use environments, which is being applied to on-farm testing of crop varieties. Over the last years, important progress has been made on the tricot methodology of which an overview is given. Trial dimensions depend on several factors but tricot implies that plot size is as small as possible to include farmers with small plots (yet avoiding excessive interplot competition) while many ...

    • Critical slope length for soil loss mitigation in maize-bean cropping systems in SW Kenya 

      Koomson, E.; Muoni, T.; Marohn, C.; Nziguheba, G.; Öborn, I.; Cadisch, G. (2020)
      Soil erosion and land fragmentation threaten agricultural production of sub-Saharan African highlands. At our study site in Western Kenya, farm size is mostly < 2 ha, laid out in narrow strips in slope direction and ploughed downhill. Soil conservation measures like hedgerows and green manures can reduce effective slope length for erosion, but compete with crops for space and labour. Knowledge of critical slope length can minimise interventions and trade–offs. Hence, a maize–bean intercrop (MzBn) ...

    • The root and tuber crop farming system: diversity, complexity and productivity potential 

      Adjei-Nsiah, S.; Asumugha, G.; Njukwe, E.; Akoroda, M. (Routledge, 2020)
      The root and tuber crop farming system occurs in west and central Africa, bounded on the southern, wetter side by the tree crop farming system and on the northern, drier side by the cereal-root crop mixed farming system. The root and tuber crop farming system occupies an estimated 236 million ha and has an estimated human population of 112 million, of whom over 50 per cent live in rural areas. Poverty is relatively high with about half the rural population earning less than US$1.25 per day. The ...
