COLONIZAÇÃO EUROPEIA NO NW DO RIO GRANDE DO SUL primeiros sinais de desequilíbrios ambientais Adriana Fátima Canova Motter Ciencias de la Tierra Paisagem Paisagem Colonização Colonização Degradação Ambiental Este artigo aborda as primeiras décadas de transformação da paisagem no noroeste do Rio Grande do Sul, no século XX, após a entrada de imigrantes europeus e seus descentes. Basicamente, a transformação da paisagem na área de estudo teve dois momentos distintos, com características diferenciadas, principalmente na intensidade das ações de intervenção no espaço. O primeiro, nas primeiras décadas, no qual os imigrantes utilizaram basicamente o fogo e instrumentos manuais (serrotes, machados, enxadas, entre outros) para a derrubada da mata e produção agrícola, e um segundo, após a segunda metade do século, com a intensificação da intervenção pela modernização da agricultura. Este, tão somente aprofundou os desequilíbrios ambientais que já vinham ocorrendo de forma menos acentuada no momento anterior, porém preocupante, especialmente na degradação do solo e da água e no ataque de “pragas” à produção agrícola, abordados neste artigo. 2015 artículo científico 1984-2201 https://www.redalyc.org/articulo.oa?id=273639441007 pt http://www.redalyc.org/revista.oa?id=2736 Mercator - Revista de Geografia da UFC application/pdf Universidade Federal do Ceará Mercator - Revista de Geografia da UFC (Brasil) Num.1 Vol.14
