Agricultural Market Performance and Determinants of Fertilizer Use in Ethiopia AgEcon
Demeke, Mulat; Kelly, Valerie A.; Jayne, Thomas S.; Said, Ali; Le Vallee, Jean-Charles; Chen, H..
This paper examines how the fertilizer sector in general, and farmers’ demand for fertilizer in particular, has evolved since the introduction of fertilizer sector reforms in Ethiopia. There is much debate in the agricultural development literature about whether fertilizer use in Africa is constrained primarily by poor input distribution systems, by farmers’ lack of knowledge concerning the benefits and correct use of fertilizer, or by lack of effective demand because the product is simply not profitable enough. This paper looks at each of these issues in an effort to understand the relative importance of the different constraints and how well current policies are addressing the problems. It attempts to identify additional policy measures needed to...

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...

Analysis of poverty and its covariates among smallholder farmers in the eastern Hararghe highlands of Ethiopia AgEcon
Bogale, Ayalneh; Korf, Benedikt.
This paper analyses the extent and determinants of rural household poverty in the eastern highlands of Ethiopia. We study 216 households using a household consumption expenditure approach. We are particularly interested in the effects of location-specific and institutional factors (networks) in determining the probability of being poor. Our findings suggest that poverty is location-specific, depends on access to irrigated land (not land per se) and access to non-farm income. Results also indicate that household wellbeing is negatively affected by household size, and positively affected by age of household head. Involvement in governance, social and production related networks is also found to be strongly associated with the probability of a household be...

ASSETS AT MARRIAGE IN RURAL ETHIOPIA AgEcon
Fafchamps, Marcel; Quisumbing, Agnes R..
This paper examines the determinants of assets at marriage in rural Ethiopia. We identify and test three separate processes that determine assets brought to marriage: assortative matching, compensating parental transfers at marriage, and strategic behavior by parents. We find ample evidence for the first, none for the second, and some evidence of the third for brides. We also find no evidence of competition for parental assets among siblings. Results suggest that parents do not transfer wealth to children in ways that compensate for marriage market outcomes. Certain parents, however, give more assets to daughters whenever doing so increases the chances of a daughter marrying a wealthy groom.

Balancing Ecosystem Services and Disservices: Smallholder Farmers’ Use and Management of Forest and Trees in an Agricultural Landscape in Southwestern Ethiopia Ecology and Society
Ango, Tola Gemechu; Department of Human Geography, Stockholm University; tola.gemechu@humangeo.su.se; Senbeta, Feyera; Center for Environment and Development Studies, College of Development Studies, Addis Ababa University ; feyeras@yahoo.com; Hylander, Kristoffer; Department of Ecology, Environment and Plant Sciences, Stockholm University; Kristoffer.Hylander@botan.su.se.
Farmers’ practices in the management of agricultural landscapes influence biodiversity with implications for livelihoods, ecosystem service provision, and biodiversity conservation. In this study, we examined how smallholding farmers in an agriculture-forest mosaic landscape in southwestern Ethiopia manage trees and forests with regard to a few selected ecosystem services and disservices that they highlighted as “beneficial” or “problematic.” Qualitative and quantitative data were collected from six villages, located both near and far from forest, using participatory field mapping and semistructured interviews, tree species inventory, focus group discussions, and observation. The study showed that...

Cereal price instability in Ethiopia: An examination of sources and policy options AgEcon
Shahidur, Rashid; Meron, Assefa.
Managing food price instability is a long standing policy challenge, which, with mixed experiences of agricultural price policy reforms, has re-emerged as a contemporary policy issue. This is particularly true for Ethiopia, where managing food price stability continues to be a formidable policy challenge. The objective of this paper is to examine the underlying causes of cereal price instabilities and to assess the policy options to manage them. It undertakes three tasks: (a) analyzes the sources and degree of cereal price instability, (b) discusses the viability of various policy options, and (c) critically reviews the country’s past, ongoing, and emerging policies for food price stabilization. The results show that the determinants of price...

Children's Educational Completion Rates and Dropouts in the Context of Ethiopia's National Poverty Reduction Strategy AgEcon
Woldehanna, Tassew; Jones, Nicola; Tefera, Bekele.
A combination of quantitative and qualitative method was used to analyse the determinants of school completion/dropout of children from primary education. A Cox box proportional hazard model was used analyse the survival of children in primary education. The findings have important implications for the formulation and revising Ethiopian Poverty Reduction Strategy Paper. While the policy focus of the 1996-initiated ESDP and the SDPRP (2002-5) on increasing educational access for all has been broadly successful, children from poor and/or highly indebted families still face significant constraints because they have to contribute to household survival through paid and unpaid work. It is therefore imperative to increase efforts to improve the livelihood options...

Climate change adaptation strategies of maize producers of the Central Rift Valley of Ethiopia JARTS
Ahmed, Musa Hasen.
The impacts of climate change are considered to be strong in countries located in tropical Africa that depend on agriculture for their food, income and livelihood. Therefore, a better understanding of the local dimensions of adaptation strategies is essential to develop appropriate measures that will mitigate adverse consequences. Hence, this study was conducted to identify the most commonly used adaptation strategies that farm households practice among a set of options to withstand the effects of climate change and to identify factors that affect the choice of climate change adaptation strategies in the Central Rift Valley of Ethiopia. To address this objective, Multivariate Probit model was used. The results of the model indicated that the likelihood of...

Climate change impacts on hydrology and water resources of the Upper Blue Nile River Basin, Ethiopia AgEcon
Kim, Ungtae; Kaluarachchi, Jagath J.; Smakhtin, Vladimir U..
The report evaluates the impacts of climate change on the hydrological regime and water resources of the Blue Nile River Basin in Ethiopia. It starts from the construction of the climate change scenarios based on the outcomes of several general circulation models (GCMs), uses a simple hydrological model to convert theses scenarios into runoff, and examines the impacts by means of a set of indices. The results, however uncertain with existing accuracy of climate models, suggest that the region is likely to have the future potential to produce hydropower, increase flow duration, and increase water storage capacity without affecting outflows to the riparian countries in the 2050s.

Collective Action and Vulnerability: Burial Societies in Rural Ethiopia AgEcon
Dercon, Stefan; Hoddinott, John; Krishnan, Pramila; Woldehanna, Tassew.
Collective action can help individuals, groups, and communities achieve common goals, thus contributing to poverty reduction. Drawing on longitudinal household and qualitative community data, the authors examine the impact of shocks on household living standards, study the correlates of participation in groups and formal and informal networks, and discuss the relationship of networks with access to other forms of capital. In this context, they assess how one form of collective action, iddir, or burial societies, help households attenuate the impact of illness. They find that iddir effectively deal with problems of asymmetric information by restricting membership geographically, imposing a membership fee, and conducting checks on how the funds were spent....

Commodity-based Trade and Market Access for Developing Country Livestock Products: The Case of Beef Exports from Ethiopia AgEcon
Rich, Karl M.; Perry, Brian D.; Kaitibie, Simeon.
While Ethiopia is Africa’s largest livestock producer, sanitary and phytosanitary (SPS) barriers and animal diseases have traditionally constrained market access. A system dynamics model examined the feasibility of a proposed SPS certification system under a number of scenarios. Model results indicate that the system may not be viable for beef exports to Middle Eastern markets. However, the binding constraint is high domestic input costs rather than the costs of SPS compliance. Sensitivity analyses reveal that while investments in feed efficiency and animal productivity would enhance Ethiopia’s export competitiveness, the competitive nature of international beef markets may still prevent market access.

Computing Opportunity Costs of Growing Local Varieties for On-farm Conservation: Illustrations Using Sorghum Data from Ethiopia AgEcon
Wale, Edilegnaw; Mburu, John G.; Estrella, Jaime.
The recent shift of emphasis to on-farm conservation is driven by its diverse attractive features - participatory nature, dynamic nature, capacity to maintain not only crop diversity but the knowledge that evolves with it, the chance it offers and the challenge it brings to link conservation with farmers' livelihood. To make it operational, placing incentives and removal of perverse incentives are of critical importance. However, before placing sound incentives compatible to farmers' circumstances, the opportunity costs farmers face when using local varieties of public interest should be understood. This paper empirically examines farmers' opportunity costs of maintaining local varieties of sorghum using a household survey data collected from 198 sorghum...

CONSUMPTION INSURANCE AND VULNERABILITY TO POVERTY: A SYNTHESIS OF THE EVIDENCE FROM BANGLADESH, ETHIOPIA, MALI, MEXICO, AND RUSSIA AgEcon
Skoufias, Emmanuel; Quisumbing, Agnes R..
This paper synthesizes the results of five studies using household panel data from Bangladesh, Ethiopia, Mali, Mexico and Russia, which examine the extent to which households are able through formal and/or informal arrangements to insure their consumption from specific economic shocks and fluctuations in their real income. Building on the recent literature of consumption smoothing and risk sharing, the degree of consumption insurance is defined by the degree to which the growth rate of household consumption covaries with the growth rate of household income. All the cases studies show that food consumption is better insured than nonfood consumption from idiosyncratic shocks. Adjustments in nonfood consumption appear to act as a mechanism for partially...

Crop Coefficient of Haricot Bean at Melkassa, Central Rift Valley of Ethiopia JARTS
Laike, Samson; Kombolcha Agricultural Technical and Vocational Education Training College, Ethiopia; Tilahun, Ketema; P.O. Box 45, Alemaya University, Ethiopia; fax: 0251-5-610713, email: ketematilahun@yahoo.com; Hordofa, Tilahun; Melkassa Agricultural Research Center, Ethiopia.
Crop coefficient (Kc), the ratio of potential crop evapotranspiration to reference evapotranspiration, is an important parameter in irrigation planning and management. However, this information is not available for many important crops. A study was carried out at the experimental farm of Melkassa Agricultural Research Center of Ethiopian Agricultural Research Organization, which is located in a semi arid climate. Four drainage type lysimeters were used to measure the daily evapotranspiration of haricot bean, Awash Melka variety on a clay loam soil. Crop coefficient was developed from measured crop evapotranspiration and reference evapotranspiration calculated using weather data. The measured values of crop coefficient for the crop were 0.34, 0.70, 1.01 and...

CROP DIVERSITY AS THE DERIVED OUTCOME OF FARMERS' 'SURVIVAL FIRST' MOTIVES IN ETHIOPIA: WHAT ROLE FOR ON-FARM CONSERVATION OF SORGHUM GENETIC RESOURCES? AgEcon
Wale, Edilegnaw; Virchow, Detlef.
Crop genetic resources are the building blocks of sustainable agricultural development due to their relevance not only as inputs for variety development but also as indigenous crop insurance mechanisms through traditional variety portfolio management. Their continuous survival is, however, threatened by natural and human driven factors. This threat has induced the need for designing conservation measures. Among the in situ and ex situ conservation options available to conserve crop genetic resources, on-farm conservation has recently attracted enormous attention. To make this option operational, placing incentives (that link conservation with utilization) and removal of perverse incentives are believed to be crucial so that landraces of no immediate...

Crop-Livestock Interactions in Smallholders’ Market Participation: Evidence from Crop-Livestock Mixed Systems in Ethiopia AgEcon
Jaleta, Moti; Gebremedhin, Berhanu.
Most studies on smallholder market participation decisions analyze crop or livestock market participation separately. However, in mixed crop-livestock farming systems, smallholders’ participation decisions in crop and livestock markets may not be separate as a household’s position in one market may be influenced by its position in the other. Where there is limited income from off-farm and/or non-farm activities, household cash requirements for crop production or household consumption are usually met by selling livestock. Similarly, livestock purchase is usually financed by income from crop sales. However, to what extent the position in one market influences the other is still not well explored in the literature. The aim of this paper is to investigate the...

Dairy development in Ethiopia AgEcon
Ahmed, Mohamed A. M.; Ehui, Simeon K.; Assefa, Yemesrach.
Ethiopia holds large potential for dairy development due to its large livestock population, the favorable climate for improved, high-yielding animal breeds, and the relatively disease-free environment for livestock. Given the considerable potential for smallholder income and employment generation from high-value dairy products, development of the dairy sector in Ethiopia can contribute significantly to poverty alleviation and nutrition in the country. Like other sectors of the economy, the dairy sector in Ethiopia has passed through three phases or turning points, following the economic and political policy in the country. In the most recent phase, characterized by the transition towards market-oriented economy, the dairy sector appears to be moving...
