Remote sensing analysis of water harvesting through contour trenches and terraces in Burundi

Evaluating the results of large‐scale land and water management project is key to ensuring their replicability and long‐term sustainability. The present work was developed within the Burundi Landscape Restoration and Resilience Project by the WorldBank (PRRPB), active from 2019 to 2024, where slow‐forming terraces were implemented together with rainwater harvesting trenches on contour lines. Such works were developed in two “communes” of the country, namely Isare and Buhinyuza, with opposite climatic conditions. For the dryer and hotter commune of Buhinyuza, the present work utilizes a set of remote sensing datasets and indicators to monitor the effects of PRRPB project, using the Google Earth Engine cloud computing platform.
