Sustainable rural food systems for poor and vulnerable people need to be locally adapted to enhance food security. This requires participatory action research that considers the entire food value chain (FVC). This paper presents an assessment of the feasibility and potential success of upgrading strategies (UPS) for enhancing food security based on a study that was part of a larger participatory research project in two regions of Tanzania. The authors present the results relating to natural resource management and crop production. The results for natural resources show that enhanced soil water management was rated as high for the semi-arid Dodoma region. For the Morogoro region, the experts favoured soil fertility-improving UPS, such as conservation agriculture and agroforestry. Assessments of food production for both regions indicated the importance of intercropping, manure input, pest and disease control and cover crops. Assessments differed greatly between the two different climatic regions, and to a lesser extent between the nationality of the experts and their gender. This highlights the importance of including different South-North and female-male awareness in assessments. Implementation feasibility assessments of UPS indicated that the most suitable approaches were rainwater harvesting for semi-arid and conservation agriculture for subhumid regions respectively. Local and/or regional stakeholders and experts should be involved in developing and assessing site-adapted UPS for enhancing Tanzanian FVCs.

Outlook on Agriculture | Year: 2015

Food security is one of the main goals of rural poor people. To enhance food security in this context, participatory action research can help to ensure sustained success while considering entire food value chains (FVC). This paper assesses the feasibility and potential success of upgrading strategies (UPS) as well as their assessment criteria as developed by German and Tanzanian agricultural scientists. The results form part of a larger participatory research project conducted in two climatically representative regions of Tanzania: semi-arid Dodoma and subhumid Morogoro. This paper presents the findings with respect to food processing, waste management and bioenergy, along with income generation and market participation. Assessments on other components of the FVC, including natural resource management, crop production and consumption, are reported by Graef et al (2015). The assessments for food processing revealed preferences for preservation techniques, oil extraction processes and food storage devices for the semi-arid region. In contrast, in the subhumid region, the experts favoured food storage devices and preservation techniques. Assessments of waste management and bioenergy UPS for both regions indicated the importance of animal feed from crop residues, crop residues as mulch and compost from food waste, although with somewhat different priorities. Assessments on income generation and markets in both regions revealed preferences for savings and credit cooperatives and communication techniques, but also indicated that warehouse receipt systems and guarantee systems had a high impact. Assessments differed between the two different climatic regions, and to some extent also between the nationality of experts and their gender. The authors therefore attach importance to integrating different South-North and female-male awareness in assessments among scientists. Moreover, local and/or regional stakeholders and experts should be involved in developing site-adapted UPS for enhancing FVCs.

Food Security | Year: 2010

Low rainfall has been blamed for the recent crop failure in Kongwa district, within Tanzania's Central Zone, when 310 out of a total of 331.2 mm of rainfall were concentrated into the first 4 months (November to February) of the 2008-09 cropping season. In May 2009, farmers in this district, expected yields from early maturing (short/intermediate) varieties of sorghum, such as Macia and Pato that were late planted in January and February, to be less than 250 kg/ha. They complained that late delivery of seed of these varieties had led to the poor yields. Records kept by thirty seven subsistence farmers throughout the cropping season indicated that an average of 62 kg of sorghum grain of both early and late maturing varieties was harvested per household by June 2009. This is sufficient for just 14 day's food supply for an average household comprising three adults, two adolescents (aged 10-18 years) and two children (aged less than 10 years). In addition, each household had accrued financial losses, averaging Tsh64, 527.65 (€33.79) from expenditure on wasted inputs. Furthermore, the high incidence of Covered Kernel Smut in sorghum fields suggested that farmers had been supplied with contaminated seed, while the limited availability of seed of the Striga-resistant sorghum varieties, Hakika and Wahi, had allowed this parasitic weed to flourish in their fields. It was estimated that these two pests could have caused sorghum losses in excess of 50%. Each household that was impoverished by this crop failure will have to raise an average of Tsh436, 070 (€228.36) to cover its grain deficit until June 2010. © Springer Science+Business Media B.V. & International Society for Plant Pathology 2010.
