Análise de viabilidade econômica e de risco da fruticultura na região norte Fluminense

The purpose of the research was to determine, through the calculation of net present value and internal return rate, the viability of fruit production in the North area of Rio de Janeiro State, as well as to identify, using the Monte Carlo Method, the risk of each activity. The results show that fruit production can be a good alternative to the region. All the analyzed activities presented satisfactory profitability, and the highest internal return rates found for passion fruit, soursop, pineapple and sugar apple. The variable with greatest effect on profitability was the product sale price, and equally important were labor cost, price of fertilizers and cost of irrigation equipment. Pineapple, cocoanut, sugar apple, passion fruit and soursop practically offered no economic risks, while the greatest risks were presented by mango and guava.

Padrão de desenvolvimento tecnológico dos municípios das Regiões Norte e Noroeste do Rio de Janeiro

The objective of the research was to characterize the degree of technological development of the North and Northwest regions of Rio de Janeiro state. Factor analyzes was used to characterize the degree of technological development. Differences between regions, concerning the technological development, were evidenced by research. A change in the pattern of the technological development, with reduction in relation to the capital-labour, was still observed since the 80s decade. This phenomenon is probably related to decrease of rural credit supply and elevation of its costs.

Estrutura fundiária das regiões Norte e Noroeste do Estado do Rio de Janeiro: 1972 a 1998

The work has as objective to investigate, using data publi-shed by the Institute for Colonization and Land Reform (INCRA), the changes in land distribution in the North and Northwest regions of the Rio de Janeiro state, in the period from 1972 to 1998. The Gini index, the average area, the percentage of the area corresponding to the 5% largest landholders, and the percentage of the area corresponding to the 50% smallest landholders, were used to describe the profile of the land distribution. The results show significant differences between the studied regions. Although both regions have a concentrated agrarian structure, the land distribution is worst in the North region. It was still observed that the agrarian structure of these regions has not presented significative changes in the period.
