Round potato (Solanum tuberosum) production in southern highlands of Tanzania: Are smallholder farmers becoming commercial?

August 2012

The subsistence production is chosen by farmers because it is subjectively the best option. However, subsistence farming on small and fragmented plots risks not reaching even farmers’ own food requirements, let alone producing a surplus. Therefore, it would have been expected that farmers would be commercialising production of profitable food crops. One of the more profitable food crops than many others as studies...

Quantification of Dothistroma septosporum spores by real-time polymerase chain reaction (PCR)

May 2012

Many fungal plant pathogens can be spread over long distances by airborne or rain splash spore dispersal. These spores can infect susceptible hosts causing disease and in some cases mortality and for this reason spore monitoring followed by control is needed. Air sampling can be combined with modern sensitive molecular methods such as quantitative polymerase chain reaction (qPCR), real-time PCR (West et al., 2008,...

Seasonality in cocoa spot and forward markets: Empirical evidence

May 2012

This paper first describes the main features of supply and demand in cocoa spot markets. A state- variable model is proposed to describe the random evolution of cocoa forward curves over time, which essentially adapts to agricultural commodities, introduced by Borovkova and Geman (2006) for energy. In contrast to most of the literature on the subject, the first state variable is not the spot price, as it combines...
