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...

Agricultural Growth, Poverty, and Nutrition in Tanzania AgEcon
Pauw, Kalie; Thurlow, James.
Rapid economic growth has failed to significantly improve poverty and nutrition outcomes in Tanzania. This raises concerns over a decoupling of growth, poverty, and nutrition. We link recent production trends to household incomes and caloric availability using a dynamic computable general equilibrium and micro-level poverty and nutrition modules. Results indicate that the structure of economic growth—not the level—is currently constraining the rate of poverty reduction in Tanzania. Agricultural growth has been driven by larger-scale farmers that are less likely to be poor. Growth has further been concentrated in crops grown in only a few regions of the country. Slow expansion of food crops and livestock also explains the weak relationship between...

Agricultural Technology Adoption and Rural Poverty: Application of an Endogenous Switching Regression for Selected East African Countries AgEcon
Asfaw, Solomon; Shiferaw, Bekele A..
Achieving agricultural growth and development and thereby improving rural household welfare will require increased efforts to provide yield enhancing and natural resources conserving technologies. Agricultural research and technological improvements are therefore crucial to increase agricultural productivity and thereby reduce poverty. However evaluation of the impact of these technologies on rural household welfare have been very limited by lack of appropriate methods and most of previous research has therefore failed to move beyond estimating economic surplus and return to research investment. This paper evaluates the potential impact of adoption of modern agricultural technologies on rural household welfare measured by crop income and consumption...

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 poor, remote areas left behind in agricultural development: the case of Tanzania AgEcon
Minot, Nicholas.
In Tanzania, as in many other developing countries, the conventional wisdom is that economic reforms may have stimulated economic growth, but that the benefits of this growth have been uneven, favoring urban households and farmers with good market access. This idea, although quite plausible, has rarely been tested empirically. In this paper, we develop a new approach to measuring trends in poverty and apply it to Tanzania in order to explore the distributional aspects of economic growth and the relationship between rural poverty and market access. We find that, between 1991 and 2003, a period of extensive economic reforms, the overall rate of poverty fell about 9 percentage points. The degree of poverty reduction was similar between rural and urban areas,...

Biogenic Assemblage and Hydrodynamic Settings of the Tidally Dominated Reef Platform Sediments of the Zanzibar Channel OceanDocs
Shaghude, Y.W.; Wannas, K.O.; Mahongo, S.B..
The biogenic assemblage and hydrodynamic settings of the tidally dominated reef platform sediments (TDRPS) east of the Zanzibar channel were investigated in order to characterise the carbonate sediments. Benthic foraminifera were found to be the most important group both in terms of average abundance (> 60 % by weight) and also in terms of spatial distribution with ommon occurrence in all sediments samples. Pelecypods with an average abundance of 8 % were slightly less widely distributed. The remaining groups occurred at lower average abundance and less frequently in the sediments. Current measurements indicated that the maximum current speed is higher during spring than during neap tides. The direction is phase-dependent with flood tidal current...

Biosafety education relevant to genetically engineered crops for academic and non-academic stakeholders in East Africa Electron. J. Biotechnol.
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...

Can REDD+ Reconcile Local Priorities and Needs with Global Mitigation Benefits? Lessons from Angai Forest, Tanzania Ecology and Society
Mustalahti, Irmeli; Development Studies, Department of Political and Economic Studies, University of Helsinki, Finland ; irmeli.mustalahti@helsinki.fi; Bolin, Anna; Independent Research Consultant, UK; bolinanna@gmail.com; Boyd, Emily; Department of Geography and Environmental Science, Whiteknights University of Reading, UK; e.boyd@leeds.ac.uk; Paavola, Jouni ; School of Earth and Environment, University of Leeds, UK; j.paavola@leeds.ac.uk.
The scope of the reducing emissions from deforestation and forest degradation (REDD) mechanism has broadened REDD+ to accommodate different country interests such as natural forests, protected areas, as well as forests under community-based management. In Tanzania the REDD+ mechanism is still under development and pilot projects are at an early stage. In this paper, we seek to understand how local priorities and needs could be met in REDD+ implementation and how these expectations match with global mitigation benefits. We examine the local priorities and needs in the use of land and forest resources in the Angai Villages Land Forest Reserve (AVLFR) in the Liwale District of Lindi Region in Tanzania. Primary data was collected in two villages, Mihumo and...

Climate Volatility and Poverty Vulnerability in Tanzania AgEcon
Ahmed, Syud Amer; Diffenbaugh, Noah S.; Hertel, Thomas W.; Ramankutty, Navin; Rios, Ana R.; Rowhani, Pedram.
Climate volatility will increase in the future, with agricultural productivity expected to become increasingly volatile as well. For Tanzania, where food production and prices are sensitive to the climate, rising climate volatility can have severe implications for poverty. We develop and use an integrated framework to estimate the poverty vulnerabilities of different socio-economic strata in Tanzania under current and future climate. We find that households across various strata are similarly vulnerable to being impoverished when considered in terms of their stratum’s populations, with poverty vulnerability of all groups higher in the 21st Century than in the late 20th Century. When the contributions of the different strata to the national poverty changes...

Coastal Aquaculture Developments in Tanzania: Sustainable and Non-sustainable Experiences OceanDocs
Bryceson, I..
Coastal aquaculture of seaweeds and prawns has developed in Tanzania during the past two decades. Farming of Eucheuma seaweeds commenced in 1989 along the east coast of Zanzibar and it has since expanded to other areas. This form of aquaculture does not pollute the environment with feeds, wastes or other chemicals, although there are some negative interactions causing inhibition of surrounding biota, but which appear to be relatively mild. Monoculture may result in some self-inhibition and disease vulnerability over time. The socio-economic impacts of seaweed farming was initially overwhelmingly positive, providing income to women from relatively poor remote villages. Annual production reached 7000 tonnes constituting an important earning of foreign...

Collective Action Initiatives to Improve Marketing Performance: Lessons from Farmer Groups in Tanzania AgEcon
Barham, James; Chitemi, Clarence.
The primary inquiry of this study is to identify and understand the underlying factors that enable smallholder farmer groups to improve their market situation. The specific objective of this paper is to examine to what extent certain group characteristics and asset endowments facilitate collective action initiatives to improve group marketing performance. This objective is approached through an evaluation of a government-led program in Tanzania, which is attempting to increase smallholder farmers’ incomes and food security through a market-oriented intervention. Findings suggest that more mature groups with strong internal institutions, functioning group activities, and a good asset base of natural capital are more likely to improve their market situation....

Commodity prices, structural constraints and food price shocks in Tanzania AgEcon
Conforti, Piero; Sarris, Alexander H..
This paper explores the impact of the recent soar in world commodity prices on economic activity and household welfare in Tanzania, and the possible policy responses to that shock. The analysis is based on a single country computable general equilibrium model that includes considerable factor market and household details, as well as marketing margins between producers, consumers and foreign markets. Results indicate that the Tanzanian economy may fail to benefit from the opportunities arising from the increase in world agricultural prices, as this would imply a considerable reduction in most production activities, but the few that are directly export oriented. Policies can counteract only to a limited extent these negative impacts. Tariff and domestic tax...

Conservation and Unscripted Development: Proximity to Park Associated with Development and Financial Diversity Ecology and Society
Baird, Timothy D.; Virginia Tech; tbaird@vt.edu.
Decades of research on the social dynamics of biodiversity conservation has shown that parks and protected areas have added hardship to rural communities throughout much of the developing world. Nonetheless, some recent studies have found evidence of poverty alleviation near protected areas. To build on these conflicting accounts, I use a comparative, mixed-methods design to examine opportunistic, unplanned, i.e., unscripted, development in indigenous communities near Tarangire National Park (TNP) in northern Tanzania. I ask the questions: (1) How is proximity to TNP related to community-level infrastructural development? (2) How has the process of development changed over time? and (3) How is proximity to TNP related to infrastructure-related social...

Consumer Perception of Sorghum Variety Attributes in the Lake Zone Tanzania AgEcon
Mafuru, January M.; Norman, David W.; Fox, J.S.
Many sorghum varieties have been developed by research institutes in an effort to address food security problems in the semi-arid areas of Tanzania. Although sorghum is better adapted to drier areas than maize, farmer adoption rates for sorghum varieties are always lower than that of maize. In addition, maize based food is more acceptable to urban consumers than sorghum based food. In this study consumer evaluated quality attributes of sorghum ugali based on different varieties in order to determine marketing potential relating to the different improved sorghum varieties. A total of 231 consumers, randomly selected from urban and rural areas participated in a food panel to evaluate ugali prepared from five sorghum varieties (three improved, two local)....

Consumer preferences as drivers of the common bean trade in Tanzania: A marketing perspective AgEcon
Mishili, Fulgence J.; Temu, Anna A.; Fulton, Joan R.; Lowenberg-DeBoer, James.
The objective of this study was to determine the impact of bean grain quality characteristics on market price. The data was collected from retail markets in Tanzania. Hedonic pricing provides a statistical estimate of premiums and discounts. Implications for development of bean markets include: i) extension agents should identify cost-effective ways to educate producers on targeting urban market niches based on consumer preferences for varieties, ii) breeding for bruchid resistant beans and use of appropriate storage technologies would alleviate the problems of storage damage, and iii) requiring a portfolio of grain quality characteristics to fit consumer preferences in local markets.
