As a result, the wetlands have begun a significant, linear decline with 67.9% water mirror loss in a nine-year period. There is also a direct relationship between wetland loss, and decreases in precipitation, and anthropization processes. It was determined, from the anthropic factor analysis, that that livestock and agricultural land use are those which cause the greatest negative effect on wetland decline in the studied area. 2018 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49658894044 https://www.redalyc.org/journal/496/49658894044/ https://www.redalyc.org/journal/496/49658894044/html/ https://www.redalyc.org/journal/496/49658894044/49658894044.epub https://www.redalyc.org/journal/496/49658894044/movil 10.15446/dyna.v85n207.69963 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.207 Vol.85 |
