Factors affecting agricultural production in Tigray Region, Northern Ethiopia

Bihon Kassa Abrha 07 1900 (has links)
This study investigates the factors affecting agricultural production of farm households in the National Regional State of Tigray, Ethiopia. The major primary sources of data for the study were farm household surveys, focus group discussions and key informant interviews. The study revealed that the annual average crop production of respondents was found to be below the standard annual food requirement recommended by the international organizations. The proportion of irrigated land to total cultivated land was only 11per cent. The proportion of irrigated land in the two districts is lower than 11.27 per cent at the regional level. The utilization of chemical fertilizers for the majority of the respondents was below the recommended standard for the region. Although the farmers were interested in using improved seeds, the supplied varieties were not based on their preferences. Extension agents were mainly engaged in activities which were not related to their professions. The farm income model result showed that landholding size (p<0.0001), possession of oxen(p<0.0001), amount of fertilizer(p=0.010), improved seeds(p=0.002), irrigation(p=0.028), soil quality(p=0.019), village distance to the district market(p=0.066), average distance of plots from the homestead (p=0.023) and crop rotation(p=0.016) were determinant variables. Farmers were engaged in off-farm activities to fulfill the cash requirements in credit constrained conditions. The laws of the region do not allow farmers to be out of their localities for more than two years and the farmerswere restricted to renting out only half of their land. This discouraged farmers from off-farm participation for fear of land confiscation. In the Probit model, the determinant variables of off-farm participation were: irrigation (p=0.001), age (p=0.007), amount of money borrowed (p=0.078), village distance to the wereda market (p=0.055), fear of land confiscation (p=0.023) and access to electricity (p=0.044). It is recommended that if farmers are to use chemical fertilizers, they should be supplied with High Yielding Varieties (HYV)and enough water through access to irrigation. Furthermore, farmers should be allowed to have long term off-farm employment to augment the farming sector. / Development Studies / D. Litt. et Phil. (Development Studies)

Farmers' collective action and agricultural transformation in Ethiopia

Etenesh Bekele Asfaw 08 1900 (has links)
Rural Ethiopia rolled-out a program for the establishment of farmers’ collective action groups known as ‘Farmers’ Development Groups’ (FDGs), in 2007, based on presumed common interest of smallholder farmers. Although the government trusts that FDGs fetch fast and widescale agricultural transformation as part of the participatory agricultural extension system, systematic study and evidence on what motivates smallholder farmers to act collectively, the group dynamics, long term impact and transformative potential of the agricultural extension groups is scarce. Using the expectancy-value theory in social-psychology, this study explores what drives smallholders to act collectively; their participation level and benefits in groups, particularly for women and the youth; and the extent to which farmers’ groups attain intended agricultural transformation goals of productivity and commercialization. The study collected a mix of qualitative and quantitative data in 2016, through 46 key informant interviews; 8 focus group discussions with farmers, and a survey of randomly selected 120 smallholder farmers (30 percent women) in four sample woredas (districts) of Ethiopia. The findings of the study are drawn through a content analysis, and descriptive and correlation analysis of the qualitative and quantitative data, respectively. The study findings show that social identity, and not ‘common interest’ motivates smallholder farmers to join and participate in FDGs. The study provides evidence that participation in FDGs enhances smallholder farmers’ adoption and use of agricultural technologies, where 96 and 84 percent of the farmers who received extension messages in the group on crop and livestock production, respectively, applied the message. Consequently, by 2015 more than 85 percent of the survey respondent farmers reported above 10 percent increase in crop and livestock productivity. Nevertheless, the nature of the incremental changes brought by the collective actions are not transformative, nor sustainable. Extension groups have limited contribution to commercialization of smallholders, where only 20 percent of the FDG members participate in output marketing. More so, FDGs avail limited collective opportunity for the landless youth, and married female farmers in a rural society where difference in power, status and privilege prevail. It also limits deviation of thought among the rural community. Limited access to inputs and technology; large family size; limited access to farm land; over dependence of the extension system on ‘model’ farmers and public extension agents, and poorly designed sustainability features bound the transformative potential of FDGs. The study forwards a set of five recommendations to unleash the potential of FDGs: reconsider the group design to be identity congruent; ensure inclusiveness for young and female farmers; empower and motivate voluntary group leaders; encourage collective marketing and; invest in sustainability features of the group. / Development Studies / Ph.

Prospects of sustainable land management amidst interlocking challenges in the Upper Beshillo Catchments, Northeastern Highlands of Ethiopia

Asnake Yimam Yesuph 06 1900 (has links)
Land degradation is a great threat to the Beshlo Catchment in Blue Nile Basisn, not merely as an environmental issue, but also a social and economic problem. In Gedalas Watershed (one of the micro catchments of Beshelo), land degradation, mediated by both biophysical and socio-economic drivers, is among the major environmental sustainability and social-economic development threats in the area. The threat is manifested in depletion of natural vegetations, water, soil and other natural resources; disruption of ecosystem functions, processes, integrity, and services. Given its particular vulnerability, watershed management activities have been in operation since the mid-1970s. Recently, the idea of Sustainable land management through integrated watershed development program has been initiated with the objective of reducing land degradation risks and ensuring food security at both the nationwide and family circle. Despite these investments and efforts, real evidences of success and failures of such efforts were not satisfactory explored. The objectives of this study were, therefore, to analyze the existing status and future prospects of sustainable land management and evaluates its implication on the environmental integrities and the local livelihoods specific to Gedalas watershed. For this effect, the study investigated the dynamics, deriving forces and implications of LULC, soil erosion and soil fertility status of the watershed, current status of watershed management practices, pertinent challenges and opportunities for practicing land management technologies and approaches that might help meet the sustainability requirements of SLM practices. In addition, the study explored factors that determine the willingness of farming households to undertake SLM practice. As the study carried in the coupled human-environment system of rural landscapes, interdisciplinary geographical approaches which integrats social and natural science methodologies were employed to deal with issues of land degradation-and-rehabilitation status comprehensively. The general findings of the study show that though it would be dificult to measure all the composite aspects of land degradation, some of the parameters considered in this study revealed that land degradation is a perpetuating challenge in the watershed. It is evidenced from the overall undesirable land use/cover changes i.e transition of 21.25% of Afro/sub alpine landscapes, 17.59% of the grasslands and 8% of shrub lands to either to cultivated land or settlement areas over the 1973–2017 period, which have unintended negative socio-ecological repercussions on the watershed; high annual mean soil loss value (which range from 37t/ha/year average values to 393 t/ha/yr soil loss rates on water courses) that exceed threshold level and a wide gap between the need for SLM and the actual achievement of SLM practices,including limited adherence to the idea behind contemporary land management policies and implementation principles and approaches. The study further revealed the presence of opportunities as well as a myriad of challenges that need to be tackled in order to achieve sustainable land management goals. The study colcludes that, though, some encouraging progresses have been observed in the SLM project sites; land degradation has remained a problem in the watershed. This calls for strenuous efforts to promote and assist wide scale adoption of SLM practices that address the pervasive land degradation problem and achieve land degradation neutrality as highlighted in sustainable development goals. / Department of Geography / Ph.

Challenges and opportunities of development in Ethiopia through urban-rural economic linkages (URELs)

Berhanu Zeleke Gobaw 07 1900 (has links)
The transformation of rural people and land to urban land and culture is a natural discourse and inevitable process. In the process, more than half of the current world population are living in urban centres. The number of urban centres and their population is rapidly increasing while the situation of integrated development of urban centres and rural areas such URELs for sustainable development have given less attention in agricultural based countries (ABCs). Multi-disciplinary (agriculture and agro-industries) integration, multi-spatial (urban centre and its hinterlands) linkages, multiscalar (micromeso and macro) levels, multi-actors and stakeholders involvement are the noteworthy innovations in the field of development studies. This study mainly focused on URELs for agribusiness and value chains under the development themes of governance and development as well as contemporary debates. Policies, institutional settings and practical implementation strategies of integrated and balanced development discourse of basic sectoral and urban-rural economic linkages (URELs) missed in ABCs such as Ethiopia‟s comprehensive development policy ADLI neglecting the rapidly growing urban centres. Owing to this, this study is designed to examine the challenges and problems, status and agribusiness and efficiencies of URELs for exploring theoretical empirical model for virtuous circle URELs. Methodologically, the study used sequential explanatory mixed methods research and cross-sectional survey design. The sequential approach was quantitative method, qualitative method and integrating the two findings on interpretation and discussion. The findings present truncated BPLs and FPLs of agriculture and agroindustries. It was was mainly due to poor and greater ranges of efficiency from TE, AE and EE for both agriculture and agro-industries, form of government as ethnic-federalism and regionalism, violation of the existing institutional frameworks, dejure-defacto discrminatin, government businesses, policy and institutional settings, lack of R&D, many paradoxical acts and poor resources mobilization and utilization. These problems and challenges are taken as potential opportunities for improvement and new lens of developing empirical model. The overall recommendation lies on creating enabling environment for virtuous circle URELs and integrated regional development using regional development approach, avoiding illegal interventions, import-export balance, proper resource mobilization and utilization. / Development Studies / D.

Livelihoods and coping strategies of rural households in Abela Lida Peasant Association of Shebedino District, Southern Ethiopia

Kemeria Barsenga Kedir 05 1900 (has links)
Executive summary: last page (unnumbered) / The Sustainable Livelihood framework approach is a comprehensive method for determination of food insecurity and poverty at household level. The objective of this study was to determine the livelihood strategies and the coping mechanisms used by rural households in Abela Lida PA, Shebedino district, Southern Ethiopia. This study used both qualitative and quantitative methods to estimate the contribution of different resources to total food access and cash income, detailing expenditure patterns, asset holdings and capacity to cope with shocks. Simple random sampling was used for selecting 72 households for the survey. The data was collected during the hunger season using the checklists designed for livelihood and coping strategies. The study showed only 30% households had all the adults as working members, due to poor work skill, low awareness and lack of job opportunities. The main sources of income are sale of cash crops mainly coffee (55.6%) followed by sale of cash crops plus livestock (18%), labour (12.5%), PSNP (8.3%). The average annual income for the households was found to be birr 4,727.92 (~$293.34) and agriculture is the main livelihood strategy. Awareness and access to basic social services has improved and escalated price of staple foods, has negatively affected poor households and safety net beneficiaries who rely on purchase. Seasonality has also affected agricultural activities, prices and employment opportunities. The increase in fuel price was found to be the main shock followed by coffee price fluctuations and failure in purchasing power of money. About (63%) households faced shortage of food or money to buy food, medical expenses, cooking fuel and school fees. / Agriculture, Animal Health and Human Ecology / M.A. (Human Ecology)
