Status and drivers of village poultry production and its efficiency in Ethiopia
In many developing countries like Ethiopia village poultry makes up a large part of the national poultry meat and egg production and plays important roles economically, nutritionally, and socio-culturally. Households in Ethiopia have not fully benefitted from the potential of village poultry as little attention is given to the sub-sector from research and development efforts. The little research and development efforts tend to explore improvements largely via technical approaches by overlooking the socio-economic and institutional context under which the producers operate. This study aims to identify the technical, household, infrastructural and institutional drivers or barriers that influence village poultry production and its productivity in Ethiopia. Across sectional survey of 5004 households was undertaken in the four highland regions of Ethiopia. Descriptive statistics and econometric tools such as probit and Heckman’s two stage models and their marginal effects were used to analyze the status and driving factors of village poultry production and productivity. Distance to all weather roads decreased flock size and the probability of poultry ownership. Contact with development agents and participation in training increased flock size and the probability of purchasing inputs and adopting commercial breeds. Flock size and ownership of commercial breeds raised households’ likelihood of purchasing poultry input. Our results indicate that research and development efforts have to improve not only production performance through better use of inputs and technologies but also have to equally emphasize increasing the benefits for smallholder producers by providing infrastructural and institutional support to proper target households.
期刊介绍:
The NJAS - Wageningen Journal of Life Sciences, published since 1952, is the quarterly journal of the Royal Netherlands Society for Agricultural Sciences. NJAS aspires to be the main scientific platform for interdisciplinary and transdisciplinary research on complex and persistent problems in agricultural production, food and nutrition security and natural resource management. The societal and technical challenges in these domains require research integrating scientific disciplines and finding novel combinations of methodologies and conceptual frameworks. Moreover, the composite nature of these problems and challenges fits transdisciplinary research approaches embedded in constructive interactions with policy and practice and crossing the boundaries between science and society. Engaging with societal debate and creating decision space is an important task of research about the diverse impacts of novel agri-food technologies or policies. The international nature of food and nutrition security (e.g. global value chains, standardisation, trade), environmental problems (e.g. climate change or competing claims on natural resources), and risks related to agriculture (e.g. the spread of plant and animal diseases) challenges researchers to focus not only on lower levels of aggregation, but certainly to use interdisciplinary research to unravel linkages between scales or to analyse dynamics at higher levels of aggregation.
NJAS recognises that the widely acknowledged need for interdisciplinary and transdisciplinary research, also increasingly expressed by policy makers and practitioners, needs a platform for creative researchers and out-of-the-box thinking in the domains of agriculture, food and environment. The journal aims to offer space for grounded, critical, and open discussions that advance the development and application of interdisciplinary and transdisciplinary research methodologies in the agricultural and life sciences.
