A decade of landscape management tools (LMT) implementation: land cover change assessment using UAS-BASED IMAGERY – A CASE STUDY in an oil palm plantation in Mapiripán, Meta, Colombia
In Colombia, oil palm is an important economic sector of the agroindustry. The main challenges are to ensure palm oil production growth and maintain the local environment and a sustainable agricultural landscape. We conducted a landscape analysis on an exemplary palm oil plantation to assess the landscape structure and land-use change between 2009 and 2019. The case study is done in the Macondo oil palm plantation, located in Mapiripán, Meta, in the eastern zone of Colombia with a total area of 5,853 hectares. The landscape analysis is based on a 2009 land cover maps GIS analysis. First, the land cover map of the plantation was divided into grid cells of 500 by 500 meters. Second, we applied landscape metrics for the landscape structure assessment and calculated a k-means cluster analysis. The grid cells were clustered into nine (9) similarity groups based on landscape metrics. Four (4) squares per group, in a total of 36, were selected as a sample of the plantation. For each selected square, we took aerial photography at a height of 100 meters to create the orthophotos. The aerial photographs were taken using Unmanned Aerial Systems (UAS), in this case, a DJI drone, and enabled us to take over 10,800 aerial photographs in 10 days. Aerial photography provides detailed and up-to-date information on land cover and land use change, which is essential for monitoring and decision-making. This landscape analysis enables plantation managers to monitor land cover change and the implemented Landscape Management Tools (LMT) within the plantation.
