A Field study to Estimate the Prevalence of Bovine African Trypanosomosis in Butaleja District, Uganda OAK
JING, Zhang; MAGONA, Joseph W; SAKURAI, Tatsuya; THEKISOE, Oriel M. M; OTIM, Charles P; SUGIMOTO, Chihiro; INOUE, Noboru; 井上, 昇.
Prevalence of bovine trypanosomosis was determined from a total of 203 blood samples collected from Butaleja district, eastern Uganda. All samples were examined by microhematocrit centrifuge test (MHC), PCR and ELISA. ELISA was performed in accordance with the OIE standard procedures using Trypanosoma brucei gambiense procyclic form crude antigens. PCR were utilized to identify the species and the subspecies of trypanosome. The overall prevalence of bovine African trypanosomosis was 8.9% by MHC, and 45.3% by the ELISA. Since substantial number (12 out of 18) of MHC positive samples were negative in the PCR tests, we could not conclude the most epidemic trypanosome species in the studied area. Nevertheless, the PCR results suggests that the most prevalent...

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...

ALTERNATIVE GROWTH SCENARIOS FOR UGANDAN COFFEE TO 2020 AgEcon
You, Liangzhi; Bolwig, Simon.
Coffee is the most important export crop in Uganda and an important source of income among smallholder farmers in large parts of the country. The Robusta type dominates coffee production and Ugandan Robusta is demanded by roasters as a component in certain blends due to its special taste qualities. However, a combination of events outside and within Uganda, especially the collapse of world coffee prices in the late 1990s, are eroding farmer incomes and export revenues and threaten the long-term viability of the industry. In this context, the paper first investigates the challenges faced by the Ugandan coffee industry, namely the decline in the world coffee market, changes in procurement strategies among coffee importers, the rapidly expanding market for...

An economic assessment of banana genetic improvement and innovation in the Lake Victoria Region of Uganda and Tanzania AgEcon
Tushemereirwe, Wilberforce K..
This research report highlights the findings from a set of studies undertaken by the International Food Policy Research Institute, along with several national and international research institutions, to assess the economic impact of improved cultivars and management practices on smallholder farmers in the Lake Victoria Region of Uganda and Tanzania— an area where the cooking banana is both economically and culturally important. Genetic transformation is a promising alternative for improving the resistance of banana plants to the pests and diseases that cause serious economic losses, because bananas, unlike rice, wheat, and maize, are difficult to improve through conventional breeding techniques. The team of researchers posed three broad questions: What is...

Are there customary rights to plants? An inquiry among the Baganda (Uganda), with special attention to gender AgEcon
Howard, Patricia L.; Nabanoga, Gorettie.
Debates around Common Property Resources and Intellectual Property Rights fail to consider traditional and indigenous rights regimes that regulate plant resource exploitation, establish bundles of powers and obligations for heterogeneous groups of users, and create differential entitlements to benefits that are related to social structures. Such rights regimes are important to maintaining biodiversity and to human welfare; failing to recognize them presents dangers. The case study investigates the gendered nature of informal rights to selected tree and plant species that are distinct from, but related to, customary rights to land and trees, and are embedded in cosmology and social norms.

Assessing the Impact of the National Agricultural Advisory Services (NAADS) in the Uganda Rural Livelihoods AgEcon
Benin, Samuel; Nkonya, Ephraim M.; Okecho, Geresom; Pender, John L.; Nahdy, Silim; Mugarura, Samuel; Kato, Edward; Kayobyo, Godfrey.
The National Agricultural Advisory Services (NAADS) program of Uganda is an innovative public-private extension service delivery approach, with the goal of increasing market oriented agricultural production by empowering farmers to demand and control agricultural advisory services. Although initial evaluations of NAADS have been quite favourable, these evaluations have been primary qualitative in nature. This study quantifies the initial impacts of NAADS in the districts and sub-counties where the program was operating by 2005. It is based on descriptive analyses of results of a survey of 116 farmer groups and 894 farmers in sixteen districts where the program was operating at the time and four districts where NAADS had not yet begun operating to control...

Benefit-Cost Analysis of Uganda’s Clonal Coffee Replanting Program: An Ex-Ante Analysis AgEcon
Benin, Samuel; You, Liangzhi.
The Ugandan coffee industry is facing some serious challenges, including low international prices in the international coffee market, aging coffee trees and declining productivity, and, more recently, the appearance of coffee-wilt disease, which have all contributed to the decline in both the quantity and value of coffee exports. The government of Uganda, through the Uganda Coffee Development Authority (UCDA), in 1993/94 started a coffee-replanting program to both replace coffee trees that were old or affected by coffee-wilt and expand coffee production into other suitable areas in northern and eastern Uganda. This program seems to be helping to both combat the industry’s problems and reverse the declining trends. However, the UCDA announced in 2004 that...

Sengooba,Theresa; Grumet,Rebecca; Hancock,James; Zawedde,Barbara; Kitandu,Lazaro; Weebadde,Cholani; Karembu,Margaret; Kenya,Eucharia; Meredia,Karim; Nampala,Paul; Ochanda,James O; Quemada,Hector; Rubindamayugi,Mugassa.
Development and deployment of genetically engineered crops requires effective environmental and food safety assessment capacity. In-country expertise is needed to make locally appropriate decisions. In April 2007, biosafety and biotechnology scientists, regulators, educators, and communicators from Kenya, Tanzania, and Uganda, met to examine the status and needs of biosafety training and educational programs in East Africa. Workshop participants emphasized the importance of developing biosafety capacity within their countries and regionally. Key recommendations included identification of key biosafety curricular components for university students; collaboration among institutions and countries; development of informational materials for non-academic...

Combating chronic poverty in Uganda: towards a new strategy AgEcon
Ssewanyana, Sarah N..
Using a panel of 3,572 households in the Northern Uganda Social Action Fund (NUSAF) region interviewed in 2004 and in 2008, the paper provides new evidence on chronic poverty in Uganda. While progress in reducing poverty rates has been impressive from 64.6 percent to 52.2 percent, the levels remain high with a significant number of persistently poor households. Four in every ten households are chronically poor of which 44.9 percent are living in extreme chronic poverty. About 37.8 percent of the households are living in transient poverty of which 67.4 percent escaped poverty during the panel period. The substantial movements out of poverty can perhaps be explained largely by the relative return of peace in the region that enabled households to engage in...

Competitiveness of Kenyan and Ugandan Maize Production: Challenges for the Future AgEcon
Nyoro, James K.; Kirimi, Lilian; Jayne, Thomas S..
The purpose of this study is to assess the costs of maize production in Kenya and Uganda, starting from the fact that there is no single “cost of production” for maize. Cost of production varies according to region, the type of technology package employed, farmers’ management practices, and the weather. In light of this, the study disaggregates cost of production into seven region/technology categories, five in Kenya and two in eastern Uganda, in order to compare the relative competitiveness of maize among these regions and technology packages. Variations in cost of production within each region/technology category reflect differences in farmer management practices and micro-variability in soils and rainfall.

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...

Determinants of social capital formation in rural Uganda: Implications for group-based agricultural extension approaches AgEcon
Katungi, Enid; Machethe, Charles Lepepeule; Smale, Melinda.
Although social capital is a potentially important asset for poverty reduction in developing economies, there has been little analysis of factors affecting its formation in developing countries such as Uganda. This paper analyzes what influences households to join local organizations and the intensity of social networks in central Uganda. Social networks were disaggregated by major activity to gain insight into household access, and the interaction between local organizations and social networks was examined. Probit and ordered probit models were estimated to identify what led households to participate in organizations and the intensity of participation. A negative binomial model was applied to analyze the household intensity of social networks. The...

Developing Poverty Assessment Tools Based on Principal Component Analysis: Results from Bangladesh, Kazakhstan, Uganda, and Peru AgEcon
Zeller, Manfred; Houssou, Nazaire; Alcaraz V., Gabriela; Schwarze, Stefan; Johannsen, Julia.
Developing accurate, yet operational poverty assessment tools to target the poorest households remains a challenge for applied policy research. This paper aims to develop poverty assessment tools for four countries: Bangladesh, Peru, Uganda, and Kazakhstan. The research applies the Principal Component Analysis (PCA) to seek the best set of variables that predict the household poverty status using easily measurable socio-economic indicators. Out of sample validations tests are performed to assess the prediction power of a tool. Finally, the PCA results are compared with those obtained from regressions models. In-sample estimation results suggest that the Quantile regression technique is the first best method in all four countries, except Kazakhstan. The PCA...

Development and Dissemination of Improved Cassava Varieties in Uganda: Analysis of Adoption Rates, Variety Attributes and Speed of Adoption AgEcon
Abele, Steffen; Twine, Edgar; Ntawuruhunga, Pheneas; Baguma, Yonah; Kanobe, Charles; Bua, Anthony.
The transition out of extreme poverty and hunger in agrarian economies requires an understanding of how new agricultural technologies are adopted by poor farmers. In Uganda, improved germplasm from the cassava breeding program has generated new varieties that are increasingly being grown by farmers. Although considerable success has been achieved in adoption of these varieties in general, there is increasing pressure on breeding and technology dissemination programs to improve the targeting of their efforts. This paper identifies the specific cassava varieties adopted thus far and their desirable and undesirable attributes. In addition, it determines the adoption rates of these varieties and the factors that have influenced the speed of adoption of the...

DEVELOPMENT PATHWAYS AND LAND MANAGEMENT IN UGANDA: CAUSES AND IMPLICATIONS AgEcon
Pender, John L.; Jagger, Pamela; Nkonya, Ephraim M.; Sserunkuuma, Dick.
This paper investigates the patterns and determinants of change in livelihood strategies (“development pathways”), land management practices, agricultural productivity, resource and human welfare conditions in Uganda since 1990, based upon a community-level survey conducted in 107 villages. The pattern of agricultural development since 1990 involved increasing specialization and commercialization of economic activities, consistent with local comparative advantages and market liberalization. This pattern was associated with changes in land use and agricultural practices, including expansion of cultivated area, grazing lands and woodlots at the expense of forest and wetlands; increased ownership of cattle but declining ownership of other livestock; and...

Economics of Fish Marketing in Central Uganda: A Preliminary Analysis AgEcon
Bukenya, James O.; Hyuha, Theodora; Twinamasiko, Julius; Molnar, Joseph J..
The paper examines profitability and market performance of small-scale fish traders selected randomly from a cross-section of nine fish markets in four districts in Central Uganda. Data were collected through a structured questionnaire which was designed to solicit information on traders’ socio-economic characteristics, marketing characteristics, operating costs and returns, and problems associated with fish marketing in the study area. Percentages were used to describe the socio-economic characteristics, market characteristic and problems associated with fish marketing while gross profit and marketing performance models were used to determine profitability, marketing margin and operational efficiency, respectively. The results suggest that fish trade is...

Effectiveness of agricultural extension with respect to farm size: The case of Uganda AgEcon
Betz, Michael R..
Raising the incomes of agricultural households is central to reducing poverty in Uganda. In many areas of the country agriculture has encroached into marginal or fragile lands, leaving little room for the expansion of agricultural lands (Kraybill, Bashaasha, and Betz 2009). Additionally, soil degradation has become a barrier to agricultural productivity (Pender et al. 2004), especially in the Eastern region of the country. Farmers now look for alternatives that will increase output without further depleting soil fertility or expanding into fragile lands. Agricultural extension is the primary government mechanism through which developing country governments attempt to improve the knowledge and methods that farmers use to increase output; However, many...

Evaluating the Impact of Land Tenure and Titling on Access to Credit in Uganda AgEcon
Petracco, Carly K.; Pender, John L..
Increasing smallholder farmers’ access to credit is a paramount concern in Africa in general and in Uganda in particular, as a means to help modernize agriculture. We use matching impact evaluation methods to assess four pair-wise comparisons: i) households who have freehold land with vs. without a title, ii) households who have customary land with vs. without a customary certificate, iii) households with a title or certificate having freehold vs. customary tenure, and iv) households without a title or certificate having freehold vs. customary tenure. Each comparison is then evaluated for the impact on access to any form of credit, formal credit and informal credit. Two matching methods were used and the results compared to test the robustness of the...
