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...

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...

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...

Understanding the Stability of Forest Reserve Boundaries in the West Mengo Region of Uganda Ecology and Society
Vogt, Nathan D; Indiana University Center for Institutions, Population, and Environmental Change; navogt@indiana.edu; Banana, Abwoli Y; Makerere University: Uganda Forest Resources and Institutions Center (UFRIC); banana@forest.mak.ac.ug; Gombya-Ssembajjwe, William; Makerere University: Uganda Forest Resources and Institutions Center (UFRIC); ufric@starcom.co.ug; Bahati, Joseph; Makerere University: Uganda Forest Resources and Institutions Center (UFRIC); bahati@forest.mak.ac.ug.
Despite heavy pressure and disturbance, state property regimes have stemmed deforestation within protected areas of the West Mengo region of Uganda for over 50 yr. In this manuscript, we reconstruct the process of creation and maintenance of forest reserve boundaries in the West Mengo region of Uganda to identify why these boundaries have largely remained stable over the long term under conditions in which they may be predicted to fail. The dramatic boundary stability in West Mengo we attribute to key aspects of institutional design and enforcement of boundaries.

Vulnerability to Weather Disasters: the Choice of Coping Strategies in Rural Uganda Ecology and Society
Helgeson, Jennifer F; London School of Economics and Political Science, Department of Geography and Environment; The Grantham Research Institute on Climate Change and the Environment; j.helgeson@lse.ac.uk; Dietz, Simon; London School of Economics and Political Science, Department of Geography and Environment; The Grantham Research Institute on Climate Change and the Environment; s.dietz@lse.ac.uk; Hochrainer-Stigler, Stefan; IIASA - International Institute for Applied Systems Analysis; hochrain@iiasa.ac.at.
When a natural disaster hits, the affected households try to cope with its impacts. A variety of coping strategies, from reducing current consumption to disposing of productive assets, may be employed. The latter strategies are especially worrisome because they may reduce the capacity of the household to generate income in the future, possibly leading to chronic poverty. We used the results of a household survey in rural Uganda to ask, first, what coping strategies would tend to be employed in the event of a weather disaster, second, given that multiple strategies can be chosen, in what combinations would they tend to be employed, and, third, given that asset-liquidation strategies can be particularly harmful for the future income prospects of households,...

GPS and GIS Methods in an African Rain Forest: Applications to Tropical Ecology and Conservation Ecology and Society
Dominy, Nathaniel J; University of Hong Kong; njdominy@hkusua.hku.hk; Duncan, Brean; Dynamac Corporation, Kennedy Space Center; DuncaBW@kscems.ksc.nasa.gov.
Since the completion of the Navstar Global Positioning System (GPS) in 1995, the integration of GPS and Geographical Information Systems (GIS) technology has expanded to a great number of ecological and conservation applications. In tropical rain forest ecology, however, the technology has remained relatively neglected, despite its great potential. Notwithstanding cost, this is principally due to (1) the difficulty of quality satellite reception beneath a dense forest canopy, and (2) a degree of spatial error unacceptable to fine-scale vegetation mapping. Here, we report on the technical use of GPS/GIS in the rain forest of Kibale National Park, Uganda, and the methodology necessary to acquire high-accuracy spatial measurements. We conclude that the...

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...

CONCURRENT TRYPANOSOMOSIS, THEILERIOSIS, ANAPLASMOSIS AND HELMINTHOSIS IN FRIESIAN, ZEBU AND SAHIWAL CATTLE IN UGANDA OAK
Magona, J. W.; Mayende, J. S. P..
An epidemiological investigation was conducted on mixed farms in Tororo and Soroti districts of Uganda from January to February 2000 to determine the cause of reported persistent mortality of cattle. Blood and faecal examination of 98 cattle comprised of 33 Friesians, 58 Zebu and 7 Sahiwal was undertaken. Results revealed 7 (7.1%) cattle had trypanosome infection, mainly due to Trypanosoma vivax and T. brucei, 17 (17.3%) had Fasciola infection, 28 (28.6%) had gastrointestinal nematode infection, 33 (33.7%) had Theileria parva infection and 13 (13.3%) had Anaplasma marginale infection. Mixed infections were detected in 24.5%, 30%, 20.6% and 43% of all cattle, Friesians, Zebu and Sahiwal respectively. Anaemia (PCV<25) was detected in 21%, 24%, 19% and 14%...

Welfare distribution and poverty in Uganda, 1992 to 2000 AgEcon
Okidi, John A.; Okwi, Paul O.; Ddumba-Ssentamu, John.
This study covers a period of far-reaching economic reform policies and programs in Uganda. Measures of inequality and stochastic dominance analysis are applied to a series of regionally representatives national household surveys data to shed light on the patterns of inter-temporal changes in levels and distribution of welfare in Uganda. Stochastic dominance analysis of welfare distribution reveals that Ugandan households were better off in 2000 and 1997 than in 1992 irrespective of the choice of a poverty line. Using a sub-regional panel data set that was constructed on the basis of rural/urban categorization we estimate elasticities of poverty with respect to growth to illustrate that deliberate policies focusing on welfare distribution would...

How Best to Target the Poor? An operational targeting of the poor using indicator-based proxy means tests AgEcon
Houssou, Nazaire; Zeller, Manfred; Alcaraz V., Gabriela; Johannsen, Julia; Schwarze, Stefan.
This paper seeks to answer an operational development question: how best to target the poor? In their endeavor, policy makers, program managers, and development practitioners face the daily challenge of targeting policies, projects, and services at the poorer strata of the population. This is also the case for microfinance institutions that seek to estimate the poverty outreach among their clients. This paper addresses these challenges. Using household survey data from Uganda, we estimate four alternative models for improving the identification of the poor in the country. Furthermore, we analyze the model sensitivity to different poverty lines and test their validity using bootstrapped simulation methods. While there is bound to be some errors, no...

Gender, Social Capital and Information Exchange in Rural Uganda AgEcon
Katungi, Enid; Smale, Melinda.
Changing agricultural research and extension systems mean that informal mechanisms of information diffusion are often the primary source of information about improved seed and practices for farmers in sub-Saharan Africa. This paper investigates the interactions between gender, social capital and information exchange in rural Uganda. Within the framework of farmer-to-farmer models, we conceptualize the informal information diffusion process to comprise social capital accumulation and information exchange. We assume that each agent participates in information exchange with a fixed (predetermined) level of social capital and examine how endowments of social capital influence information exchange, paying close attention to gender differences. A multinomial...

The paradox of household resource endowment and land productivity in Uganda AgEcon
Ainembabazi, John Herbert; Angelsen, Arild.
The paper investigates the conflicting findings in empirical studies linking land productivity to plot size, livestock ownership, investment in farm assets, and land improvement practices. The conflicting impacts found are partly as a result of different model specifications, the type of data used – panel or cross sectional data – and possibly due to imperfections in rural markets. We control for these problems using household and plot level panel data from rural farmers in Uganda. We find that ownership of cattle has a negative and significant impact on land productivity. Investment in farm related assets, land improvements and other small livestock, however, significantly increases productivity. The conflicting impacts are a result of measurement error....

LINKAGES BETWEEN POVERTY AND LAND MANAGEMENT IN RURAL UGANDA: EVIDENCE FROM THE UGANDA NATIONAL HOUSEHOLD SURVEY, 1999/00 AgEcon
Pender, John L.; Ssewanyana, Sarah N.; Edward, Kato; Nkonya, Ephraim M..
This study investigates the impacts of rural poverty on farmers' land management decisions, crop production and incomes, based upon analysis of data from the 1999/2000 Uganda National Household Survey. We find that the impacts of rural poverty on land management, crop production and income depend upon the type of poverty (i.e., what asset or access factor is constrained) and the type of land management considered. Ugandan households that are poorer in terms of access to land use labor more intensively and are less likely to use several land management practices and inputs, though among households that do use non-labor inputs, land-poor households use many of these inputs more intensively. As a result, land-poor households obtain higher value of crop...

Of What Merit is Improved Inputs use in Uganda's Maize Productivity? AgEcon
Okoboi, Geofrey.
This paper used the Uganda National Household Survey (UNHS) dataset of 2005/06 to examine the productivity of improved inputs used by smallholder maize farmers in Uganda. Yield and gross profit functions were estimated with the stochastic frontier model. Results revealed a significant effect improved inputs use on yield but not gross profit. Farmers who used commercial improved seed with fertiliser obtained superior yield but lower gross profit compared to farmers who planted recycled seed (of improved variety) without fertiliser. Furthermore, if the opportunity cost of own land and labour inputs in maize production were imputed, overall, farmers made economic losses. Based on the prevailing farmers’ production technology and market conditions, maize...

The potential gains from geographical targeting of anti-poverty programs in Uganda AgEcon
Kraybill, David S.; Bashaasha, Bernard.
Governments do not have enough resources to make anti-poverty programs available to everyone in many African countries. Targeting the poorest populations could increase the efficiency of available program resources. Anti-poverty programs could target either households or geographical areas. This study compares the potential poverty reduction impact of these two approaches in Uganda. The impact of various policy changes on the poverty rate in Uganda is simulated using the estimated parameters of an econometric model of household consumption. The policies examined are family-planning, increased primary school attendance, increased secondary school attendance, expansion of formal employment and micro-enterprise expansion. The results reveal gains in poverty...

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...

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...
