Análise das sustentabilidade no processo produtivo de hortaliças realizado por agricultores familiares na comunidade de Várzea Cumprida dos Oliveiras - Pombal /PB.

Abstract

Climatic phenomena observed lately in different points of the earth , where regions have high temperatures , and other thermometers reach negative numbers never before seen . Can signify a warning from nature to mankind on the effects that human activities cause to the ecosystem . Among the various factors that may explain these phenomena are rampant population growth , globalization and rising consumption in immeasurable proportions. Based on these, the need arises for studies and research showing vigorous and immediate action on the resolution or mitigation of impacts to the environment . Thus , the study on the Community of Lowland Long of Olives in the municipality of Pombal , high Paraiba backwoods , aims to analyze the sustainability of the production process vegetables that family agriculture develops , from the social, economic , institutional / technological and environmental . As research methodology questionnaires were applied in situ , forty (40 ) producing families of vegetables , and laboratory analyzes to identify water quality and some vegetables grown . The data collected with the questionnaire were translated into indicators , using the method of UNDP / UN (1998 ) , whose results ranged from 0 (zero ) to 100 ( one hundred) and were divided into four grades of sustainabilities : critical , bad , good and excellent. They were then applied to the mathematical formula called GSI ( Global Sustainability Index ) developed by González and Carvajal (2002 ) . The results point to the social and economic dimensions with good rates , almost excellent for sustainability , with 71 % and 74 % , respectively. Have the institutional / technological and environmental dimensions , both were considered bad for sustainability , with their percentages, 47 % and 27 % . In the case of the environmental dimension , the result approached the very critical situation , which is 25 % . With the results of the calculated dimensions IGS was 54.75 % , meaning a good point index sustainable view. Thus , the results obtained indicate that the activity of horticulture in the community studied , is on the threshold field of sustainability , ie with index slightly above average needed to sustainability aspects . It is necessary to review the actions of the dimensions worked mainly environmental , aiming to steadily strengthen the productive process vegetables in the community with sustainable practices .
