Book (stand-alone)Technical studyEvaluation des ressources forestières ligneuses dans la République Centrafricaine
EC/FAO ACP Collecte de données - Rapport Technique AFDCA/TR/03
1999Also available in:
No results found.A medium-size report that deals with the overall situation of data on fuelwood in the Central African Republic. The report is composed of three main parts; the first section is a short description of the country and the terms of the study. The second part is an evaluation of the country's forest cover while the third part states the forest parameters (number of trees, volume, etc.) followed by a conclusion. -
Book (stand-alone)Technical bookDonnées Statistiques Sur Les Produits Forestiers Non Ligneux en Republique Centrafricaine
EC/FAO ACP collecte et analyse de données - rapport technique : AFDCA/TN/14
1999Also available in:
No results found.Based on the information available in Central Africa, this report identifies the main NWFP available as well as their uses. Their classification and management systems are described as are the main actors involved in harvesting and commercialisation of these products. Finally, the national level of importance of NWFPs is estimated. -

Les difficults recontres dans la gestion des fonds propres des stations ainsi que dans la disponibilit des crdits gouvernementaux d'entretien et de fonctionnement ont fait que l'tat gnral des stations a t en se dtriorant.

Devant cette situation, un effort considrable a t ralis pour remettre en tat satisfaisant les principales structures de production, dans les trois stations principales.

Book (stand-alone)Technical bookLand use/land cover and forest cover mapping in Nigeria 2020
Also available in:
No results found.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. -
Book (stand-alone)Technical bookWest African Land Cover Reference System 2022
Also available in:
No results found.There is an increasing necessity to provide timely and updated information about the status of land resources. It is well-known that land degradation not only results in reduced food production but also in reduced environmental quality, life conditions and health. In West Africa, the most conspicuous symptoms of the negative impact of land degradation on food production are stagnating and declining yields and increasing levels of poverty. There is an increasing need and interest to strengthen regional collaboration for sustainable development through a better understanding of land dynamics. -
Book (series)Evaluation reportMid-term evaluation of the project "Monitoring water productivity by remote sensing as a tool to assess possibilities to reduce water productivity gaps
Project code: GCP/INT/229/NET
2020Also available in:
No results found.While population growth and economic development are putting unprecedented pressure on renewable, but finite water resources, especially in arid regions, scarce land and water resources are affecting food security and sustainable water management. FAO identified the need to implement a digital database built upon remote sensing and information technologies that can monitor and report on agricultural water productivity over Africa and Near East, accessible through the FAO Water Productivity through Open access of Remotely sensed derived data portal (WaPOR). The WaPOR database is now operational at continental level (all African and Near East countries covered by the 250 m spatial resolution data), national level (two beneficiary countries can access the WaPOR database at 100 m resolution) and subnational level with a spatial resolution of about 30 m, so far including eight areas of interest (river basins or irrigation schemes). Water Accounting Plus (WA+) reports based on remote sensing have been completed for three river basins as planned (Litani in Lebanon, Awash in Ethiopia and Jordan basin). An action framework at national level for capacity building and participatory decision making is currently being developed to make effective a “demand-driven” approach based on national and local needs.
