Role of education and extension in the adoption of technology: a study of upland rice and soybean farmers in Central-West Brazil. Agric. Econ., 5: 341-359.This paper explores reduced form determinants of the adoption of certain technologies by upland rice and soybean farmers in the Center-West region of Brazil. We merge community level data on the availability and quality of publicly provided infrastructure, principally extension, to the farm level data containing information on farmer human capital as well as land quantity and quality. By using community level measures of availability and quality of extension, we avoid problems of endogeneity of farm level measures of extension use. We find positive impacts of farmer education on the diffusion process, in accordance with other studies. We also isolate effects of the quality in regional extension investment as measured by the average experience of technical extension staff. These results indicate that investments in human capital of extension workers does have 11 payoff in terms of farmer adoption of improved cultivation practices.

No artigo são exploradas as possibilidades de desenvolvimento dos territórios rurais brasileiros mais pobres. São analisadas as condições de vida dos agricultores locais entrevistados em 7.975 domicílios rurais de 37 territórios de todo o país. Enquanto cerca de 80% dos agricultores revelam ter ativos disponíveis para a produção agropecuária, apenas 20% têm boas condições de comercialização e acesso às políticas agrícolas.
A década de 1970 pode ser considerada o início do processo de modernizaçãoda agricultura brasileira. Esse processo representou uma nova concepção, que visavaa alterar a base técnica da produção e elevar os padrões de produtividade do setor. Oobjetivo geral deste estudo é fundamentado na investigação, por meio de uma medidade produtividade total dos fatores (PTF), dos condicionantes da produtividade daslavouras de cana-de-açúcar, milho e soja nas microrregiões de Goiás, para os períodosde 1985, 1995/96 e 2006. Goiás posicionou-se como um dos principais polos dedesenvolvimento nacional das atividades relacionadas ao agronegócio. As culturasselecionadas representam os principais itens da pauta de produção do estado em termosde área plantada e volume de produção. Para estimar a medida de produtividade, foiutilizado o índice de Malmquist, estimado com o auxílio da metodologia DEA – DataEnvelopment Analysis. Os resultados da pesquisa apontam que entre o período de1985-2006 foram registrados expressivos ganhos em produtividade para as três culturasselecionadas.
