1. Estimating soybean crop areas using spectral-temporal surfaces derived from MODIS images in Mato Grosso, Brazil.
Abstract ? The objective of this work was to evaluate the application of the spectral-temporal response surface (STRS) classification method on Moderate Resolution Imaging Spectroradiometer (MODIS, 250 m) sensor images in order to estimate soybean areas in Mato Grosso state, Brazil. The classification was carried out using the maximum likelihood algorithm (M

2. Condicionantes da produção do tomate de mesa na região de Campinas,SP / Factors that affect tomato production in the region of Campinas,SP
The planting of tomato has a special relevance in Brazil, for its representation in area planted and the second most important vegetable crop growing area, with over three million tons. Thus, it is important to review how it is structured the production system and how it relates to the other links in the chain. The objective of this study was to characterize

3. Uma reflexÃo sobre os possÃveis impactos do crescimento da demanda dos biocombustÃveis na oferta e preÃos das commodities agrÃcolas
The food market has changed. The use of liquid biofuels as an alternative to fossil fuel changed the crop and vegetable oil international markets, adding an important consumer sector of the economy: the energy sector. The rapid growth of biofuels demand and supply has a number of effects on the crop and vegetable oil markets, pressuring upward the agricultur

4. Estimating summer crops area using TM/Landsat-5 data from pre-planting season / Imagens TM/Landsat-5 da época de pré-plantio para a previsão da área de culturas de verão
Estimation of cultivated areas with agricultural crops is important for economic policy making. In Brazil, there is a lack of objective techniques for that purpose. Remote sensing seems to be valuable for crop acreage estimations in a large scale. However, cloud cover at the time of summer season has impaired the use of optical remote sensing images for eval
