摘要: The Re-Greening of the West African Sahel has attracted great interdisciplinary interest since it was originally detected in mid-2000s. Studies have investigated vegetation patterns at regional scales using a time series coarse resolution remote sensing analyses. Fewer attempted to explain processes behind these local scales. This research investigates bottom-up driving Sahelian greening northern Central Plateau Burkina Faso—a region recognized as hot spot. objective understand relationship between soil and water conservation (SWC) measures presence trees through comparative case study three village terroirs, which been site long-term human ecology fieldwork. Research specifically tests hypothesis that there is positive SWC tree cover. Methods include high-resolution satellite imagery aerial photos; GIS procedures; chi-square statistical tests. Results indicate that, across all sites, significant association (chi-square = 20.144, p ≤ 0.01). Decomposing this by site, however, points out not uniform. Tree cover strongly associated with investments only one village—the most 39.098, pilot concludes promotes but heavily modified contexts.
