ADOPTION OF MAIZE AND WHEAT TECHNOLOGIES IN EASTERN AFRICA: A SYNTHESIS OF THE FINDINGS OF 22 CASE STUDIES AgEcon
Doss, Cheryl R.; Mwangi, Wilfred; Verkuijl, Hugo; De Groote, Hugo.
This paper synthesizes the findings of 22 micro-level studies on technology adoption carried out by the International Maize and Wheat Improvement Center (CIMMYT) with national agricultural research systems in Ethiopia, Kenya, Tanzania, and Uganda from 1996-1999. The authors found that technology adoption is taking place across Eastern Africa but considerable scope remains to improve the productivity of smallholder agriculture in higher potential regions with high levels of adoption. Extension was the variable most highly correlated with technology adoption, and extension services continue to play an important role in disseminating information on new varieties and how to manage them. Despite the usefulness of the micro-study results, especially for priority...

Strategies for Sustainable Land Management and Poverty Reduction in Uganda AgEcon
Nkonya, Ephraim M.; Pender, John L.; Jagger, Pamela; Sserunkuuma, Dick; Kaizzi, Crammer; Ssali, Henry.
Poverty reduction is one of the overarching objectives of most of Sub-Saharan Africa and other low-income countries. Accordingly, one of IFPRI’s major research themes focuses on policies and strategies for poverty reduction. This research report contributes knowledge to that theme. It also contributes to IFPRI’s ongoing investigation of policies and strategies that foster broad-based and environmentally sustainable agricultural and rural development. In Uganda, where soil erosion and depletion of soil nutrients are widespread, land degradation is a major cause of declining productivity and increasing poverty. In this study, Ephraim Nkonya and his colleagues measure the relative merits of various household income strategies and land management practices in...

The Impact of Coffee Price Changes on Rural Households in Uganda AgEcon
Bussolo, Maurizio; Godart, Olivier; Lay, Jann; Thiele, Rainer.
Based on household survey data, this paper investigates the impact on coffee and non-coffee households of the pronounced coffee price fluctuations in Uganda during the 1990s. As expected, the price boom of the early 1990s was associated with substantial poverty reduction for coffee farmers. More strikingly, their poverty incidence continued to go down when prices fell again. This may be explained by a combination of factors: first, coffee production increased after 1995, probably as a delayed response to improved price incentives; second, there is evidence of consumption smoothing among specialized coffee farmers; and third, coffee farmers diversified into alternative crops. Non-coffee farmers seem to have benefited from the income generated through the...

Waste to energy technologies for solid waste management a case study of Uganda CIGR Journal
Miito, Gilbert John; Banadda, Noble.
Municipal solid waste management is one of the major environmental problems of developing countries. Investments in solid waste management would not only translate into jobs and income but also a cleaner environment. Over years a number of solid waste management technologies have been carried out in many developing parts of the world. Some were successful in generating lasting impacts on the improvement of solid waste management, however, many technologies failed due to unsustainability. This is partly attributed to differences in waste characteristics between developed countries and the less developed countries and the resource constraints in less developed countries. On the other hand, less developed countries are also known for being energy deprived and...

Investigating the effect of different loading densities on selected properties of dried coffee using a GHE dryer CIGR Journal
Menya, Emmanuel; Komakech, A. J..
Despite coffee being one of the leading cash crops in Uganda contributing 20%-30% of the total export earnings, it is mainly dried on bare earth surfaces hence its drastic decline in quality.  A possible alternative solution is utilization of the greenhouse effect (GHE) solar dryer.  This research was aimed at investigating the effect of different loading densities on selected properties of dried coffee using a GHE dryer that was designed and constructed at Makerere University Agricultural Research Institute Kabanyolo (MUARIK).  The research involved determining the drying time for the loading densities of 5, 10 and 20 kg m-2 as well as analyzing the coffee quality at the end of the drying period.  Three experimental runs were set up in the months of June...

Design of waste stabilization ponds for dairy processing plants in Uganda CIGR Journal
Menya, Emmanuel; Wangi, G. M.; Amanyire, F.; Ebangu, B..
Waste stabilization ponds (WSP) were designed to treat 287.5 m3 day-1 of wastewater generated from processing of 100 m3 of milk per day.  The design involved use of existing models including those developed by Mara to size the anaerobic, facultative and maturation ponds.  The design temperature was 250C.  The anaerobic pond was designed based on volumetric organic loading rate while facultative pond was designed based on surface loading rate.  On the other hand, the maturation pond was designed based on the number of coliform bacteria removed per 100 mL of wastewater.  The anaerobic pond was designed to remove 70% BOD, facultative pond-75% and maturation pond-25% BOD.  In addition, the maturation pond was designed to have a coliform bacteria removal...
