AGROBIODIVERSITY AND ENVIRONMENTAL SERVICES: PROSPECTS FOR ECOLOGICAL MANAGEMENT AGROECOSYSTEMS OF THE STATE OF PARÁ

Abstract

ABSTRACT: Agrobiodiversity, or agricultural diversity, is an important part of biodiversity and encompasses all elements that interact in agricultural production and is an essential component of sustainable agricultural systems. Thus, this work aimed to analyze the prospects for sustainable management of soil and pests in agroecosystems Pará, through the maintenance of agrobiodiversity in productive activities. We used data from 143 municipalities in Pará, from the 2006 Agricultural Census, provided by the Brazilian Institute of Geography and Statistics (IBGE) and the Municipalities Annual Production (MAP) for the same year. We used factor analysis, an important technique of multivariate statistical analysis, which were estimated by factor scores, which were estimated indexes used in the analysis. To calculate the IDA Performance Index (Agricultural) and 17 variables were used in the IDP Performance Index (Livestock) were used five variables, referring to all 143 municipalities in Pará. In the search for sustainable agricultural systems in the state of Pará, low-input and energy-efficient strategy is to restore the diversity of the agricultural landscape in and around the agricultural establishment, in which diversity can be improved over time, which can be achieved through crop rotation for example, and in space, one can optimize the form of cover crops, adopt polycultures, agroforestry systems, hedgerows, conservation of forest fragments, riparian corridors and, among other .   KEY-WORDS: agriculture, farming family, sustainability.
