Description

  • The Authors present an analysis of land cover with the application of classification techniques and probability sampling of satellite imagery for estimating forest extent and deforestation in Lake Maracaibo Basin
  • The principal findings shows a drastic decrease in forest cover as a result of anthropogenic agricultural and urban expansion, ranging from low to high rates, and differences in patterns between Venezuela and Colombia.
  • Specific findings include: current forest cover is 29,710 km2, 61% of forests belong to Venezuela and 39% falls within the Colombian region, deforestation levels was low in 85% of the basin but high deforestation (<2.5%/y) was found in three sub-basins.
  • This paper indicates that deforestation drivers in these regions can be attributed to agricultural, cattle ranching and urban expansion, also there are areas affected by the construction of roads and infrastructure for tourism expansion.
