Última A comparative analysis of the technical efficiency of rain-fed and smallholder irrigation in Ethiopia AgEcon Makombe, Godswill; Namara, Regassa E.; Hagos, Fitsum; Awulachew, Seleshi Bekele; Ayana, Mekonnen; Bossio, Deborah A.. Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains...

M.; NASCIMENTO, T.. O presente trabalho teve como objetivo descrever e avaliar, de maneira global e quantitativa, o uso de indicadores de desempenho destinados a orientar intervencoes para o aprimoramento do desempenho em projetos de irrigacao. Com a implementacao do programa de pesquisa sobre avaliacao do desempenho da irrigacao no Brasil (Projeto RPIP-Brasil) uma das areas-piloto selecionadas foi o Distrito de Irrigacao Senador Nilo Coelho. Varios indicadores relacionados a area irrigada, ao requerimento e fornecimento de agua, a energia e a tarifa de agua, foram quantificados e analisados, apresentando um perfil do desempenho do perimetro irrigado, alem de apresentarem resultados promissores ao longo dos anos verificando-se, tambem, uma interdependencia entre eles.

Ano: 2001 URL: http://www.alice.cnptia.embrapa.br/alice/handle/doc/134430 Importance of irrigated agriculture to the Ethiopian economy: Capturing the direct net benefits of irrigation AgEcon Hagos, Fitsum; Makombe, Godswill; Namara, Regassa E.; Awulachew, Seleshi Bekele. Irrigation development has been identified as a means to stimulate economic growth and rural development in Ethiopia. However, little attempt has been made to quantify the contribution of irrigation to national income. Using data from selected irrigation schemes, representing small, medium and large-scale schemes of modern or traditional typologies; the present coverage and planned growth of irrigation, actual and expected contributions of irrigation to the national economy were quantified following the approach of adjusted gross margin analysis. Our results show that irrigation yields 219.7% higher income compared to the rainfed system while its current and future contribution to agricultural GDP is estimated to be about 5.7 and 12% although irrigation...

A. V.; NOEL, A.; CAVALCANTI, E. de B.; ARAUJO, J. L. P.; FRAGA, A. F.. Para amenizar o fenomeno das secas que, frequentemente, provoca perdas das producoes agricolas na regiao semi-arida do Nordeste brasileiro, gerando fome, miseria e exodo rural, o governo tem implantado diversos perimetros irrigados ou investido em locais com potencial para desenvolver agropecuaria de sequeiro na regiao. Atraves dessas iniciativas, o governo tem criado importantes centros de producao agricola, no que diz respeito as pequenas, medias e grandes empresas de producao de frutas e hortalicas. Nas areas de irrigacao publica onde foram assentados um grande numero de familias de baixa renda, esse desenvolvimento nao tem se dado de forma uniforme para todos os colonos e as razoes apresentadas sao diversas.
