Knowledge about irrigated agricultural area and its geographical distribution are of great importance to water resources management. Evolution of irrigated area according to the irrigation method allows an identification of rational water technologies. The aim of this work was to analyze the information presented in the agricultural census of 1995/1996 and of 2006. Brazil has an area of 4.45 million cultivated hectares with irrigation. It is noticed that according to the 1995/1996 census, the irrigated area increased 1.3 million hectares, a growth of 42%. The Southeast region surpasses the South region which had, in 1995/96, the largest irrigated area. The Northeast region is the third irrigated agricultural area with 22.12 %, while the Central-west and the Northern region together sum 14.7%. According to the agricultural census 2006 classification, sprinkler irrigation (without center pivot) method is the most used,followed by flood, center pivot, other methods, drip and furrow, representing 35.3%, 24.4%, 18.9%, 8.3%, 7.4% and 5.8%, respectively.

La desigualdad regional y productiva puede originarse a partir del proceso de modernización agrícola, donde una parte de los agentes son capaces de incorporar y absorber el contenido tecnológico, pero otros permanecen al margen no solo del entorno organizacional innovador, sino también de los procesos de aprendizaje y difusión de las nuevas técnicas y conocimientos productivos. Aquí se analiza la agricultura familiar, comparándola en términos regionales y por grupos de productores con alto, medio y bajo contenido tecnológico. Además, se calcula el índice de desigualdad productiva (Gini del ingreso bruto) de las regiones Norte, Nordeste, Centro-Oeste, Sudeste y Sur. Se argumenta que, frente a la diferenciación regional, la envergadura de los emprendimientos y los diversos niveles de incremento tecnológico, las políticas públicas deben tender a reducir las diferencias perjudiciales para la difusión de los nuevos conocimientos y el aumento de la productividad de los agentes, proporcionando una mayor inclusión productiva.

This article discusses the policy implications of agricultural modernization implemented by the military - after 1964. This policy, which became known as the Green Revolution, on the one hand contributed to the development of big business, but another caused serious social and environmental impacts. Currently, not only in Brazil but all over the world, have been in a great debate about the need to find alternatives to contain the problems caused to the environment resulting from the use of high technology in the field. One alternative proposed by several researchers is to replace fossil fuels by biofuels. As we believe that the error is in the current model of agricultural production based on mass production, which serves the major markets, the attention in this article, the need to develop an agricultural model designed for small property, with the use of family work and agroecology.

This study examines how the youth's Professional projects in new generation of family farmers are prepared and the perspective of reproduction of the familiar mode of production. The sociological task is to specify the distinctive features of the situation of the youth in family farming, seeking to identify the elements considered in the preparation of their professional projects. Qualitative data were produced by a case study of young farmers who lives in the city of Faxinal do Soturno, a municipality belonging to the fourth colony of Italian immigration in Rio Grande do Sul/Brazil. We performed 36 interviews, consisting of open questions, adopting a semi-structured script, wich were examined by de method of content analysis. Among the results, were observed a context marked by professional projects that breaks with the succession of the family farm work. The negative ratings on agricultural work stand out, particularly on issues related to health, salubrity of work and conditions of aging in rural areas. Family and emotional issues, and also specific aspects of the juvenile condition, marked by the pursuit of autonomy and emancipation, permeate the professional projects in development and show a complex analytical framework, wich amplify the explanatory factors of migration of youth.
