The purpose of this thesis is to understand how small scale farmers navigate the market to access and participate in the formal maize market to improve their revenue, utilising the case of the P4P program inKenya. The empirical material was collected during fieldwork in Kenya. Qualitative methods were found to be the most suitable for this thesis. The methods that was utilised were a case study strategy, semi structured interviews, focus groups, observations and analysis of secondary sources. In this study different approaches about farmers’ organisations (FO) and small scale farmers’ access to and participation in markets have been utilised to create an analytical context. The study found that food markets in developing countries are lacking in infrastructure, market information and bank credit. The dynamics of the Kenyan market are even more complicated due to its two different marketing channels. Using collective action has the farmers overcome many of these limitations. One change is in the farmers’ mind set from viewing agriculture as a hobby to a business. The farmers have been criticised for defaulting on their contracts, whereas WFP has been criticised delays in payments. Some FO:s have been more successful than others which are a reflection of the barriers within the P4P program itself.

Very few recent studies have been done in South Africa on the occurrence or prevalence of parasites in humans. Based on the results of routine examinations for parasitic infections conducted in the Microbiology Laboratory of Ampath in Pretoria, this study focuses on the spectrum of parasites diagnosed in samples from humans in Gauteng, North West and Mpumalanga provinces between 2009 and 2010. Database searches for results of samples in which parasites were positively identified were conducted using the laboratory’s internal software system. Data of the positive results were exported and sorted according to date, specimen type, parasite identified, patient age, gender and geographic locality. Results showed that a total of 24 different species of parasites were identified in the laboratory over the two-year period. The overall numbers of parasites identified, according to the data searches, were 863 and 1061 in 2009 and 2010, respectively. The following parasites were identified: Entamoeba coli, Entamoeba histolytica, Endolimax nana, Acanthamoeba sp, Giardia intestinalis, Trichomonas hominis, Trichomonas vaginalis, Chilomastix mesnili, Blastocystis hominis, Cryptosporidium spp, Cystoisospora belli, Sarcocystis sp, Enterobius vermicularis, Ascaris lumbricoides, Trichuris trichiura, ancylostomatids (hookworm), Taenia saginata, Taenia solium, Dipylidium caninum, Inermicapsifer madagascariensis, Bertiella studeri, Schistosoma haematobium, Echinococcus granulosus and Cordylobia anthropophaga. In both years, the majority of cases originated from Gauteng Province followed by North West and Mpumalanga provinces. The data were summarized descriptively and compared with available published records. / Dissertation (MSc)--University of Pretoria, 2013. / gm2014 / Veterinary Tropical Diseases / unrestricted
