Gendered trends in commercializing and diversifying smallholder farming systems in East Africa]Intensifying inequality? Gendered trends in commercializing and diversifying smallholder farming systems in East Africa

New technologies must be developed in sub-Saharan Africa which are sustainable and economically viable. This paper discusses a methodology for measuring the agricultural sustainability and economic viability of tropical farming systems for new technology evaluation. The approach is based on the c...

A longterm experiment was conducted on Alfisols at Ibadan, Nigeria, to assess agricultural productivity and sustainability of different farming systems. The experiment, conducted for a 10 year period from 1979 to 1988, was implemented in two phases. The effects of methods of land clearing on crop...

Soil and water conservation (SWC) practices like that of erosion control and soil fertility measures were commonly practiced in the semiarid region of southern Mali since the 1980s. The SWC practices were mainly meant to increase water availability in the subsurface, reduce farm water runoff and ...

Seed systems have an important role in the distribution of high-quality seed and improved varieties. The structure of seed networks also helps to determine the epidemiological risk for seedborne disease. We present a new approach for evaluating the epidemiological role of nodes in seed networks, ...


Buddenhagen, C.Hernández Nopsa, J.F.Andersen, Kelsey F.Andrade-Piedra, J.L.Forbes, G.Kromann, P.Thomas-Sharma, SaraUseche, PilarGarrett, K.A.[Epidemic network analysis for mitigation of invasive pathogens in seed systems: potato in Ecuador]Epidemic network analysis for mitigation of invasive pathogens in seed systems: potato in Ecuador

Background and aims Replacing paddy rice by upland systems such as maize cultivation is an on-going trend in SE Asia caused by increasing water scarcity and higher demand for meat. How such land management changes will feedback on soil C and N cycles and soil greenhouse gas emissions is not well...

This chapter discusses four species of grain legumes of the lowland tropics—that is, peanuts, pigeon peas, cowpeas, and mung beans. Various aspects of these species, such as plant improvement, plant protection, growth processes, and management are described. These four species made up 87% of both...

This article provides an assessment of the potential impact of operationalizing agricultural innovation platforms (IPs) in the Sudan Savannah zone of Nigeria on adoption of improved maize/legume crop varieties, as measured by the potential outcome approach. The results show that, if the whole pop...

Maize (Zea mays L.) hybrids resistant to Striga hermonthica (Del) Benth and tolerant to drought are vital to the sustainability of productivity of the maize-based farming systems of West and Central Africa (WCA). Thirty-six diallel crosses derived from nine early maturing white maize inbreds were...
