    Land use/land cover and forest cover mapping in Nigeria 2020

    Within the framework of a Technical Assistance (TA) Agreement (UTF/NIR/066/NIR), the Food and Agriculture Organization of the United Nations (FAO), provided technical support to the Federal Government of Nigeria to undertake a number of activities, which included land use/land cover analysis and production of an updated land cover/land use map for Nigeria. An existing national classification system, adopted by FORMECU in 1998, and comprising 36 classes was aggregated into 12 classes and used for this purpose. A land use/land cover map for 1995 based on the 12 classes was also produced. The land use/land cover analysis were undertaken in SEPAL and SEPAL-CEO (SEPAL-Collect Earth Online) which is an open-source, cloud-based platform. Map mosaics for 2006 and 2016 were produced from free Landsat images extracted from the SEPAL archives and classification was then undertaken to Collect Earth Online using the 12 aggregated land use/land cover classes. The procedure required the use of higher resolution images such as SPOT 5, GeoEye, and IKONOS images. A total of 1667 training data points were collected across the 12 land cover classes over the entire country. Fieldwork (ground-truthing) was carried out in six states to verify and clarify unresolved areas especially among savannas and arable land, tree crop plantation and forest plantation, freshwater forest and mangrove; and led to the collection of 252 additional training data points.

    This pioneering study by FAO and many partners presents preliminary results of the first pilot global assessment of trees, forest and land use in the world at global and continent level. More than 500 experts with knowledge of the land and land uses in specific regions conducted the assessment, using freely available satellite imagery and a newly developed survey methodology.
