What are the agro-ecological zones in Nigeria?

The country has six distinct agro-ecological zones transiting in south-north direction from the Atlantic coast to the arid savanna of Sahel. These are the Mangrove Swamp, Rainforest, Derived savanna, Guinea savanna, Sudan savanna and Sahel savanna zones.

What is the meaning of agro-ecological zone?

An Agro-ecological Zone is a land resource mapping unit, defined in terms of climate, landform and soils, and/or land cover, and having a specific range of potentials and constraints for land use (FAO 1996). There are several systems for describing Agro-ecological zones in the Tropics.

How many agro-ecological zones are there?

twenty agro-ecological zones
The National Bureau of Soil Survey & Land Use Planning (NBSS&LUP) came up with twenty agro-ecological zones based on the growing period as an integrated criteria of effective rainfall, soil groups, delineated boundaries adjusted to district boundaries with a minimal number of regions.

What are the 5 ecological zones in Africa?

AEZ classification, shown in Figure 1, divides Africa into five ecosystem types depending upon temperature and precipitation: semi-arid, dry savannah, moist savannah, sub-humid, and humid forest.

Where are the agro ecological zones in Africa?

Western zone: covers Kigoma and Tabora regions. Southern highlands zone which includes Mbeya, Iringa, Njombe, Ruvuma, and Rukwa regions. Due to changes in regional administrative boundaries, some regions were not present during the construction of the Agro-ecological map above.

What are the different vegetation zones in Nigeria?

Nigerian vegetation zones. Vegetation usually depends on the climate zones of the country. Vegetation belts in Nigeria reflect the tight link between the vegetation and the country’s climate: Rainforest; Fresh Water Swamp; Sahel Savanna; Short Grass Savanna;

Which is the best definition of agro-ecological zoning?

Specific programmes can then be formulated to provide the most effective support to each zone.. Agro-ecalogical zoning (AEZ), as applied in FAO studies, defines zones on the basis of combinations of soil, landform and climatic characteristics.

How to make an agro-ecological zone inventory?

2.1 analyse length of growing period (LGP); 2.2 define thermal zones; 2.3 compile climatic resource inventory; 2.4 compile soil and landform resource inventory; 2.5 compile present land use inventory; 2.6 combine above to make land resources inventory based on agro-ecological zones or agro-ecological cells.
