A quick review of the production and commercialization of the main vegetables in Brazil and the world from 1970 to 2015
Provedor de dados: Horticultura Brasileira
Autores: Camargo Filho,Waldemar P; Camargo,Felipe P.
ABSTRACT In the biennium 2013-14, the world produced 1,134.27 million tons of vegetables annually. The production of garlic, onion, potato, tomato and watermelon accounted for 66.5% of the total. Brazil, in 2012, considering 40 vegetables, produced around 23 million tons, in 900.0 thousand hectares. Potatoes, tomatoes (table and processing), onions, watermelons, carrots, sweet potatoes, lettuce and cabbage, the main vegetables in Brazil, accounted for 64.0% of the total. This work presents the evolution of production, commercialization, and availability of garlic, onions, potatoes, tomatoes and watermelons in Brazil and in the world. In Brazil, the work focused on two distinct periods: 1970-1990 {when the Support Program for Production and...

The objective of this work was to evaluate a simple, semi‑automated methodology for mapping cropland areas in the state of Mato Grosso, Brazil. A Fourier transform was applied over a time series of vegetation index products from the moderate resolution imaging spectroradiometer (Modis) sensor. This procedure allows for the evaluation of the amplitude of the periodic changes in vegetation response through time and the identification of areas with strong seasonal variation related to crop production. Annual cropland masks from 2006 to 2009 were generated and municipal cropland areas were estimated through remote sensing. We observed good agreement with official statistics on planted area, especially for municipalities with more than 10% of cropland cover (R²...
